+
+Welcome to cJSON.
+
+cJSON aims to be the dumbest possible parser that you can get your job done with.
+It's a single file of C, and a single header file.
+
+JSON is described best here: http://www.json.org/
+It's like XML, but fat-free. You use it to move data around, store things, or just
+generally represent your program's state.
+
+
+First up, how do I build?
+Add cJSON.c to your project, and put cJSON.h somewhere in the header search path.
+For example, to build the test app:
+
+gcc cJSON.c test.c -o test -lm
+./test
+
+
+As a library, cJSON exists to take away as much legwork as it can, but not get in your way.
+As a point of pragmatism (i.e. ignoring the truth), I'm going to say that you can use it
+in one of two modes: Auto and Manual. Let's have a quick run-through.
+
+
+I lifted some JSON from this page: http://www.json.org/fatfree.html
+That page inspired me to write cJSON, which is a parser that tries to share the same
+philosophy as JSON itself. Simple, dumb, out of the way.
+
+Some JSON:
+{
+    "name": "Jack (\"Bee\") Nimble", 
+    "format": {
+        "type":       "rect", 
+        "width":      1920, 
+        "height":     1080, 
+        "interlace":  false, 
+        "frame rate": 24
+    }
+}
+
+Assume that you got this from a file, a webserver, or magic JSON elves, whatever,
+you have a char * to it. Everything is a cJSON struct.
+Get it parsed:
+	cJSON *root = cJSON_Parse(my_json_string);
+
+This is an object. We're in C. We don't have objects. But we do have structs.
+What's the framerate?
+
+	cJSON *format = cJSON_GetObjectItem(root,"format");
+	int framerate = cJSON_GetObjectItem(format,"frame rate")->valueint;
+
+
+Want to change the framerate?
+	cJSON_GetObjectItem(format,"frame rate")->valueint=25;
+	
+Back to disk?
+	char *rendered=cJSON_Print(root);
+
+Finished? Delete the root (this takes care of everything else).
+	cJSON_Delete(root);
+
+That's AUTO mode. If you're going to use Auto mode, you really ought to check pointers
+before you dereference them. If you want to see how you'd build this struct in code?
+	cJSON *root,*fmt;
+	root=cJSON_CreateObject();	
+	cJSON_AddItemToObject(root, "name", cJSON_CreateString("Jack (\"Bee\") Nimble"));
+	cJSON_AddItemToObject(root, "format", fmt=cJSON_CreateObject());
+	cJSON_AddStringToObject(fmt,"type",		"rect");
+	cJSON_AddNumberToObject(fmt,"width",		1920);
+	cJSON_AddNumberToObject(fmt,"height",		1080);
+	cJSON_AddFalseToObject (fmt,"interlace");
+	cJSON_AddNumberToObject(fmt,"frame rate",	24);
+
+Hopefully we can agree that's not a lot of code? There's no overhead, no unnecessary setup.
+Look at test.c for a bunch of nice examples, mostly all ripped off the json.org site, and
+a few from elsewhere.
+
+What about manual mode? First up you need some detail.
+Let's cover how the cJSON objects represent the JSON data.
+cJSON doesn't distinguish arrays from objects in handling; just type.
+Each cJSON has, potentially, a child, siblings, value, a name.
+
+The root object has: Object Type and a Child
+The Child has name "name", with value "Jack ("Bee") Nimble", and a sibling:
+Sibling has type Object, name "format", and a child.
+That child has type String, name "type", value "rect", and a sibling:
+Sibling has type Number, name "width", value 1920, and a sibling:
+Sibling has type Number, name "height", value 1080, and a sibling:
+Sibling hs type False, name "interlace", and a sibling:
+Sibling has type Number, name "frame rate", value 24
+
+Here's the structure:
+typedef struct cJSON {
+	struct cJSON *next,*prev;
+	struct cJSON *child;
+
+	int type;
+
+	char *valuestring;
+	int valueint;
+	double valuedouble;
+
+	char *string;
+} cJSON;
+
+By default all values are 0 unless set by virtue of being meaningful.
+
+next/prev is a doubly linked list of siblings. next takes you to your sibling,
+prev takes you back from your sibling to you.
+Only objects and arrays have a "child", and it's the head of the doubly linked list.
+A "child" entry will have prev==0, but next potentially points on. The last sibling has next=0.
+The type expresses Null/True/False/Number/String/Array/Object, all of which are #defined in
+cJSON.h
+
+A Number has valueint and valuedouble. If you're expecting an int, read valueint, if not read
+valuedouble.
+
+Any entry which is in the linked list which is the child of an object will have a "string"
+which is the "name" of the entry. When I said "name" in the above example, that's "string".
+"string" is the JSON name for the 'variable name' if you will.
+
+Now you can trivially walk the lists, recursively, and parse as you please.
+You can invoke cJSON_Parse to get cJSON to parse for you, and then you can take
+the root object, and traverse the structure (which is, formally, an N-tree),
+and tokenise as you please. If you wanted to build a callback style parser, this is how
+you'd do it (just an example, since these things are very specific):
+
+void parse_and_callback(cJSON *item,const char *prefix)
+{
+	while (item)
+	{
+		char *newprefix=malloc(strlen(prefix)+strlen(item->name)+2);
+		sprintf(newprefix,"%s/%s",prefix,item->name);
+		int dorecurse=callback(newprefix, item->type, item);
+		if (item->child && dorecurse) parse_and_callback(item->child,newprefix);
+		item=item->next;
+		free(newprefix);
+	}
+}
+
+The prefix process will build you a separated list, to simplify your callback handling.
+The 'dorecurse' flag would let the callback decide to handle sub-arrays on it's own, or
+let you invoke it per-item. For the item above, your callback might look like this:
+
+int callback(const char *name,int type,cJSON *item)
+{
+	if (!strcmp(name,"name"))	{ /* populate name */ }
+	else if (!strcmp(name,"format/type")	{ /* handle "rect" */ }
+	else if (!strcmp(name,"format/width")	{ /* 800 */ }
+	else if (!strcmp(name,"format/height")	{ /* 600 */ }
+	else if (!strcmp(name,"format/interlace")	{ /* false */ }
+	else if (!strcmp(name,"format/frame rate")	{ /* 24 */ }
+	return 1;
+}
+
+Alternatively, you might like to parse iteratively.
+You'd use:
+
+void parse_object(cJSON *item)
+{
+	int i; for (i=0;i<cJSON_GetArraySize(item);i++)
+	{
+		cJSON *subitem=cJSON_GetArrayItem(item,i);
+		// handle subitem.	
+	}
+}
+
+Or, for PROPER manual mode:
+
+void parse_object(cJSON *item)
+{
+	cJSON *subitem=item->child;
+	while (subitem)
+	{
+		// handle subitem
+		if (subitem->child) parse_object(subitem->child);
+		
+		subitem=subitem->next;
+	}
+}
+
+Of course, this should look familiar, since this is just a stripped-down version
+of the callback-parser.
+
+This should cover most uses you'll find for parsing. The rest should be possible
+to infer.. and if in doubt, read the source! There's not a lot of it! ;)
+
+
+In terms of constructing JSON data, the example code above is the right way to do it.
+You can, of course, hand your sub-objects to other functions to populate.
+Also, if you find a use for it, you can manually build the objects.
+For instance, suppose you wanted to build an array of objects?
+
+cJSON *objects[24];
+
+cJSON *Create_array_of_anything(cJSON **items,int num)
+{
+	int i;cJSON *prev, *root=cJSON_CreateArray();
+	for (i=0;i<24;i++)
+	{
+		if (!i)	root->child=objects[i];
+		else	prev->next=objects[i], objects[i]->prev=prev;
+		prev=objects[i];
+	}
+	return root;
+}
+	
+and simply: Create_array_of_anything(objects,24);
+
+cJSON doesn't make any assumptions about what order you create things in.
+You can attach the objects, as above, and later add children to each
+of those objects.
+
+As soon as you call cJSON_Print, it renders the structure to text.
+
+
+
+The test.c code shows how to handle a bunch of typical cases. If you uncomment
+the code, it'll load, parse and print a bunch of test files, also from json.org,
+which are more complex than I'd care to try and stash into a const char array[].
+
+
+Enjoy cJSON!

+Creative Commons Legal Code
+
+CC0 1.0 Universal
+
+    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
+    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+    HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+    surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+    warranties of any kind concerning the Work, express, implied,
+    statutory or otherwise, including without limitation warranties of
+    title, merchantability, fitness for a particular purpose, non
+    infringement, or the absence of latent or other defects, accuracy, or
+    the present or absence of errors, whether or not discoverable, all to
+    the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+    that may apply to the Work or any use thereof, including without
+    limitation any person's Copyright and Related Rights in the Work.
+    Further, Affirmer disclaims responsibility for obtaining any necessary
+    consents, permissions or other rights required for any use of the
+    Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+    party to this document and has no duty or obligation with respect to
+    this CC0 or use of the Work.

+<p>FatFs is a generic FAT/exFAT file system module for small embedded systems. The FatFs module is written in compliance with ANSI C (C89) and completely separated from the disk I/O layer. Therefore it is independent of the platform. It can be incorporated into small microcontrollers with limited resource, such as 8051, PIC, AVR, ARM, Z80, 78K and etc. Also Petit FatFs module for tiny microcontrollers is available <a href="http://elm-chan.org/fsw/ff/00index_p.html">here</a>.</p>
+
+<h4>Features</h4>
+<ul>
+ <li>Windows compatible FAT/exFAT file system.</li>
+ <li>Platform independent. Easy to port.</li>
+ <li>Very small footprint for program code and work area.</li>
+ <li>Various <a href="en/config.html">configuration options</a> to support for:
+  <ul>
+   <li>Multiple volumes (physical drives and partitions).</li>
+   <li>Multiple ANSI/OEM code pages including DBCS.</li>
+   <li>Long file name in ANSI/OEM or Unicode.</li>
+   <li>exFAT file system.</li>

+<h3>How to Port</h3>
+
+<h4>Basic considerations</h4>
+<p>The FatFs module is assuming following conditions on portability.</p>
+<ul>
+<li>ANSI C<br>
+The FatFs module is a middleware written in ANSI C (C89). There is no platform dependence, so long as the compiler is in compliance with ANSI C.</li>
+<li>Size of integer types<br>
+The FatFs module assumes that size of <tt>char</tt>/<tt>short</tt>/<tt>long</tt> are 8/16/32 bit and <tt>int</tt> is 16 or 32 bit. These correspondence are defined in <tt>integer.h</tt>. This will not be a problem on most compilers. When a conflict with existing definitions is occured, you must resolve it with care.</li>
+</ul>
+
+<h4>System organizations</h4>
+<p>The dependency diagram shown below is a typical but not specific configuration of the embedded system with FatFs module.</p>
+<p><img src="../res/modules.png" width="580" height="280" alt="dependency diagram"></p>
+<p>(a) If a working disk module with FatFs disk interface is provided, nothing else will be needed. (b) To attach existing disk drivers with different interface, glue functions are needed to translate the interfaces between FatFs and the drivers.</p>
+<p><img src="../res/funcs.png" width="750" height="420" alt="functional diagram"></p>
+
+<h4>The functions required</h4>
+<p>You need to provide only low level disk I/O functions required by FatFs module and nothing else. If a working disk module for the target system is already existing, you need to write only glue functions to attach it to the FatFs module. If not, you need to port any other disk module or write it from scratch. Most of defined functions are not that always required. For example, disk write function is not required at read-only configuration. Following table shows which function is required depends on the configuration options.</p>
+<table class="lst2">
+<tr><th>Function</th><th>Required when</th><th>Note</th></tr>
+<tr><td>disk_status<br>disk_initialize<br>disk_read</td><td>Always</td><td rowspan="5">Disk I/O functions.<br>Samples available in ffsample.zip.<br>There are many implementations on the web.</td></tr>
+<tr><td>disk_write<br>get_fattime<br>disk_ioctl (CTRL_SYNC)</td><td>_FS_READONLY == 0</td></tr>

+<tr><td>disk_ioctl (GET_SECTOR_SIZE)</td><td>_MAX_SS != _MIN_SS</td></tr>

+<h3>Long File Name</h3>
+<p>FatFs module supports long file name (LFN). The two different file names, short file name (SFN) and LFN, of a file is transparent on the API except for <tt>f_readdir</tt> function. The support for LFN is disabled by default. To enable the LFN, set <tt><a href="config.html#use_lfn">_USE_LFN</a></tt> to 1, 2 or 3, and add <tt>option/unicode.c</tt> to the project. The LFN requiers a certain working buffer in addition. The buffer size can be configured by <tt><a href="config.html#max_lfn">_MAX_LFN</a></tt> according to the available memory. The length of an LFN will be up to 255 characters, so that the <tt>_MAX_LFN</tt> should be set to 255 for all file names. If the size of working buffer is insufficient for the input file name, the file function fails with <tt>FR_INVALID_NAME</tt>. When use any re-entry to the API with LFN is enabled, <tt>_USE_LFN</tt> must be set to 2 or 3. In this case, the file function allocates the working buffer on the stack or heap. The working buffer occupies <tt>(_MAX_LFN + 1) * 2</tt> bytes and additional 608 bytes when exFAT enabled.</p>

+<p>When the LFN is enabled, the module size will be increased depends on the configured code page. Right table shows how much code size increased when LFN is enabled with some code pages. Especially, in the CJK region, tens of thousands of characters are being used. Unfortunately, it requires a huge OEM-Unicode bidirectional conversion table and the module size will be drastically increased as shown in the table. As the result, the FatFs with LFN enebled with those code pages will not able to be ported on the most 8-bit MCU systems.</p>
+<p>Note that the support for LFN on the FAT volume is a patent of Microsoft Corporation. This is not the case on FAT32 but most FAT32 drivers come with the support for LFN. FatFs can switch the LFN on/off by configuration option. When enable LFN on the commercial products, you will need to be licensed by Microsoft depends on the final destination of the products.</p>

+
+<div class="para doc" id="unicode">
+<h3>Unicode API</h3>
+<p>By default, FatFs uses ANSI/OEM code set on the API even at LFN configuration. FatFs can also switch the character encoding on the API to Unicode by configuration option <tt><a href="config.html#lfn_unicode">_LFN_UNICODE</a></tt>. This means that FatFs supports the full featured LFN specification. The data type <tt>TCHAR</tt> specifies strings on the API is an alias of <tt>char</tt>(ANSI/OEM) or <tt>WCHAR</tt>(UTF-16). For more information, refer to the description in the <a href="filename.html#uni">file name</a>.</p>

+<div class="para doc" id="exfat">
+<h3>exFAT File System</h3>
+<p>The exFAT (Microsoft's Extended File Allocation Table) file system is a replacement of the FAT file system which has been widely used in the embedded systems and consumer devices. It is adopted by SDA (SD Association) as a recommended file system for high capacity SD cards (&gt;32GB) and they are being shipped with this format, so that the exFAT will soon become one of the standard file systems for removable media.</p>
+<p>The exFAT file system allows the file size larger than 4 GiB limit what FAT file system allows upto and some file system overhead, especially file allocation delay, are reduced as well. This feature improves the write throughput to the file. However a problem on the current implementation of FatFs is that write throughput at writing to the growing edge of the fragmented file gets less than the throughput on the FAT volume. Pre-allocating a contiguous block with <tt>f_expand</tt> function may be a workaround of this problem.</p>
+<p>Note that the exFAT is a patent of Microsoft Corporation. The exFAT function of FatFs is an implementation based on US. Pat. App. Pub. No. 2009/0164440 A1. FatFs module can swich the exFAT on/off by configuration option. When enable the exFAT on the commercial products, you will need to be licensed by Microsoft depends on the final destination of the products.</p></div>
+<p><em>Remark: Enabling exFAT discards C89 compatibility because of need for 64-bit integer type.</em></p>
+
+<div class="para doc" id="reentrant">
+<h3>Re-entrancy</h3>
+<p>The file operations to the different volume is always re-entrant regardless of configurations except when LFN enabled with static working buffer. It can work simultaneously without any mutual exclusion.</p>
+<p>The file operations to the same volume is not re-entrant but it can also be configured thread-safe by option <tt><a href="config.html#fs_reentrant">_FS_REENTRANT</a></tt>. It enables to control exclusive use of each file system object. In this case, also the OS dependent synchronization object control functions, <tt>ff_cre_syncobj/ff_del_syncobj/ff_req_grant/ff_rel_grant</tt>, needed to be added to the project. There are some examples in the <tt>option/syscall.c</tt>.</p>
+<p>When a file function is called while the volume is being accessed by other task, the file function to the volume will be suspended until that task leaves the file function. If the wait time exceeded a period defined by <tt>_TIMEOUT</tt>, the file function will abort with <tt>FR_TIMEOUT</tt>. The timeout function might not be supported on the some RTOSs.</p>
+<p>There is an exception on the re-entrancy for <tt>f_mount/f_mkfs/f_fdisk</tt> function. These volume management functions are not re-entrant to the same volume and corresponding physical drive. When use these functions, other tasks need to avoid to access the volume.</p>
+<p>Note that this section describes on the re-entrancy of the FatFs module itself. The <tt>_FS_REENTRANT</tt> controls only exclusive use of each file system object and it does not that prevent to re-enter the low level disk functions. For example, only <tt>disk_status</tt> function can be re-entered at single volume system and any disk function can be re-entered at multiple volume system. Thus the low level disk I/O layer must be always thread-safe when any FatFs API is re-entered by two or more tasks.</p>
+</div>
+
+<div class="para doc" id="dup">
+<h3>Duplicated File Access</h3>
+<p>FatFs module does not support the read/write collision control of duplicated open to a file. The duplicated open is permitted only when each of open method to a file is read mode. The duplicated open with one or more write mode to a file is always prohibited, and also open file must not be renamed or deleted. A violation of these rules can cause data colluption.</p>
+<p>The file lock control can be enabled by <tt><a href="config.html#fs_lock">_FS_LOCK</a></tt> option. The value of option defines the number of open objects to manage simultaneously. In this case, if any open, rename or remove that violating the file shareing rule that described above is attempted, the file function will rejected with <tt>FR_LOCKED</tt>. If number of open objects, files and sub-directories, is equal to <tt>_FS_LOCK</tt>, an extra <tt>f_open/f_opendir</tt> function will fail with <tt>FR_TOO_MANY_OPEN_FILES</tt>.</p>
+</div>
+
+<div class="para doc" id="fs1">
+<h3>Performance Effective File Access</h3>
+<p>For good read/write throughput on the small embedded systems with limited size of memory, application programmer should consider what process is done in the FatFs module. The file data on the volume is transferred in following sequence by <tt>f_read</tt> function.</p>
+<p>Figure 1. Sector misaligned read (short)<br>
+<img src="../res/f1.png" width="490" height="110" alt="">
+</p>
+<p>Figure 2. Sector misaligned read (long)<br>
+<img src="../res/f2.png" width="490" height="140" alt="">
+</p>
+<p>Figure 3. Fully sector aligned read<br>
+<img src="../res/f3.png" width="490" height="119" alt="">
+</p>
+<p>The file I/O buffer is a sector buffer to read/write a part of data on the sector. The sector buffer is either file private sector buffer on each file object or shared sector buffer in the file system object. The buffer configuration option <tt><a href="config.html#fs_tiny">_FS_TINY</a></tt> determins which sector buffer is used for the file data transfer. When tiny buffer configuration (1) is selected, data memory consumption is reduced <tt>_MAX_SS</tt> bytes each file object. In this case, FatFs module uses only a sector buffer in the file system object for file data transfer and FAT/directory access. The disadvantage of the tiny buffer configuration is: the FAT data cached in the sector buffer will be lost by file data transfer and it must be reloaded at every cluster boundary. However it will be suitable for most application from view point of the decent performance and low memory comsumption.</p>
+<p>Figure 1 shows that a partial sector, sector misaligned part of the file, is transferred via the file I/O buffer. At long data transfer shown in Figure 2, middle of transfer data that covers one or more sector is transferred to the application buffer directly. Figure 3 shows that the case of entier transfer data is aligned to the sector boundary. In this case, file I/O buffer is not used. On the direct transfer, the maximum extent of sectors are read with <tt>disk_read</tt> function at a time but the multiple sector transfer is divided at cluster boundary even if it is contiguous.</p>
+<p>Therefore taking effort to sector aligned read/write accesss eliminates buffered data transfer and the read/write performance will be improved. Besides the effect, cached FAT data will not be flushed by file data transfer at the tiny configuration, so that it can achieve same performance as non-tiny configuration with small memory footprint.</p>

+<h3>Considerations on Flash Memory Media</h3>
+<p>To maximize the write performance of flash memory media, such as SDC, CFC and U Disk, it must be controlled in consideration of its characteristitcs.</p>
+<h4>Using Mutiple-Sector Write</h4>
+<div class="rset">
+Figure 6. Comparison between Multiple/Single Sector Write<br>
+<img src="../res/f6.png" width="630" height="148" alt="fig.6">
+</div>
+<p>The write throughput of the flash memory media becomes the worst at single sector write transaction. The write throughput increases as the number of sectors per a write transaction as shown in Figure 6. This effect more appers at faster interface speed and the performance ratio often becomes grater than ten. <a href="../res/rwtest2.png">This graph</a> is clearly explaining how fast is multiple block write (W:16K, 32 sectors) than single block write (W:100, 1 sector), and also larger card tends to be slow at single block write. Number of write transactions also affects life time of the flash memory media. When compared at same amount of write data, the single sector write in Figure 6 above wears flash memory media 16 times more than multiple sector write in Figure 6 below. Single sector write is pretty pain for the flash memory media.</p>
+<p>Therefore the application program should write the data in large block as possible. The ideal write chunk size and alighment is size of sector, and size of cluster is the best. Of course all layers between the application and the storage device must have consideration on multiple sector write, however most of open-source memory card drivers lack it. Do not split a multiple sector write request into single sector write transactions or the write throughput gets poor. Note that FatFs module and its sample disk drivers supprt multiple sector read/write operation. </p>
+<h4>Forcing Memory Erase</h4>
+<p>When remove a file with <tt>f_unlink</tt> function, the data clusters occupied by the file are marked 'free' on the FAT. But the data sectors containing the file data are not that applied any process, so that the file data left occupies a part of the flash memory array as 'live block'. If the file data can be erased on removing the file, those data blocks will be turned into the free block pool. This may skip internal block erase operation to the data block on next write operation. As the result the write performance might be improved. FatFs can manage this function by setting <tt><a href="config.html#use_trim">_USE_TRIM</a></tt> to 1. Note that this is an expectation of internal process of the storage device and not that always effective. Most applications will not need this function. Also <tt>f_unlink</tt> function can take a time when remove a large file.</p>

+
+<div class="para doc" id="critical">
+<h3>Critical Section</h3>
+<p>If a write operation to the FAT volume is interrupted due to an accidental failure, such as sudden blackout, incorrect media removal and unrecoverable disk error, the FAT structure on the volume can be broken. Following images shows the critical section of the FatFs module.</p>
+<div class="lset">

+<img src="../res/f5.png" width="320" height="436" alt="fig.5">
+</div>
+<br class="clr">
+<p>An interruption in the red section can cause a cross link; as a result, the object being changed can be lost. If an interruption in the yellow section is occured, there is one or more possibility listed below.</p>
+<ul>
+<li>The file data being rewrited is collapsed.</li>
+<li>The file being appended returns initial state.</li>
+<li>The file created as new is gone.</li>
+<li>The file created as new or overwritten remains but no content.</li>
+<li>Efficiency of disk use gets worse due to lost clusters.</li>
+</ul>
+<p>Each case does not affect the files that not opened in write mode. To minimize risk of data loss, the critical section can be minimized by minimizing the time that file is opened in write mode or using <tt>f_sync</tt> function as shown in Figure 5.</p>

+<h3>Volume/Drive Configurations</h3>
+
+<h4 id="volumes">_VOLUMES</h4>
+<p>This option configures number of volumes (logical drives, from 1 to 10) to be used.</p>
+
+<h4 id="str_volume_id">_STR_VOLUME_ID</h4>
+<p>Disable (0) or Enable (1). This option switches the support for string volume ID. When enabled, also pre-defined strings in <tt>_VOLUME_STRS</tt> can be used as drive identifier in the path name.</p>
+
+<h4 id="volume_strs">_VOLUME_STRS</h4>
+<p>This option defines the drive ID strings for each logical drives. Number of items must not be less than <tt>_VOLUMES</tt>. Valid characters for the drive ID string are: A-Z and 0-9.</p>
+
+<h4 id="multi_partition">_MULTI_PARTITION</h4>
+<p>Disable (0) or Enable (1). This option switches multi-partition function. By default (0), each logical drive number is bound to the same physical drive number and only an FAT volume in the physical drive is mounted. When enabled, each logical drive is bound to the partition on the physical drive listed in the user defined partition resolution table <tt>VolToPart[]</tt>. Also <tt>f_fdisk</tt> funciton will be available. For more information, read <a href="filename.html#vol">here</a>.</p>
+
+<h4 id="max_ss">_MIN_SS, _MAX_SS</h4>
+<p>This set of options defines the size of sector on low level disk I/O interface, <tt>disk_read</tt> and <tt>disk_write</tt> function. Valid values are 512, 1024, 2048 and 4096. <tt>_MIN_SS</tt> defines minimum sector size and <tt>_MAX_SS</tt> defines the maximum sector size. Always set both 512 for any type of memory card and harddisk. But a larger value may be required for on-board flash memory and some type of optical media. When <tt>_MAX_SS &gt; _MIN_SS</tt>, FatFs is configured to variable sector size and <tt>GET_SECTOR_SIZE</tt> command must be implemented to the <tt>disk_ioctl</tt> function.</p>
+
+<h4 id="use_trim">_USE_TRIM</h4>
+<p>Disable (0) or Enable (1). This option switches ATA-TRIM function. To enable Trim function, also <tt>CTRL_TRIM</tt> command should be implemented to the <tt>disk_ioctl</tt> function.</p>
+
+<h4 id="fs_nofsinfo">_FS_NOFSINFO</h4>
+<p>0 to 3. If you need to know correct free space on the FAT32 volume, set bit 0 of this option, and <tt>f_getfree</tt> function at first time after volume mount will force a full FAT scan. Bit 1 controls the use of last allocated cluster number.</p>

+<h3>System Configurations</h3>
+
+<h4 id="fs_tiny">_FS_TINY</h4>
+<p>Normal (0) or Tiny (1). At the tiny configuration, size of the file object <tt>FIL</tt> is reduced <tt>_MAX_SS</tt> bytes. Instead of private data buffer eliminated from the file object, common sector buffer in the file system object <tt>FATFS</tt> is used for the file data transfer.</p>
+
+<h4 id="fs_exfat">_FS_EXFAT</h4>
+<p>This option switches support for the exFAT file system in addition to the FAT file system, Enabled(1) or Disabled(1). To enable this feature, also LFN must be enabled and configureing <tt>_LFN_UNICODE = 1</tt> and <tt>_MAX_LFN = 255</tt> is recommended for full-featured exFAT function. Note that enabling exFAT discards C89 compatibility because of need for 64-bit integer type.</p>
+
+<h4 id="fs_nortc">_FS_NORTC</h4>
+<p>Use RTC (0) or Do not use RTC (1). This option controls timestamp function. If the system does not have an RTC function or valid timestamp is not needed, set <tt>_FS_NORTC</tt> to 1 to disable the timestamp function. Any object modified by FatFs will have a fixed timestamp defined by <tt>_NORTC_MON</tt>, <tt>_NORTC_MDAY</tt> and <tt>_NORTC_YEAR</tt>. To use the timestamp function, set <tt>_FS_NORTC = 0</tt> and add <tt>get_fattime</tt> function to the project to get the current time form real-time clock. This option has no effect at read-only configuration.</p>
+
+<h4 id="nortc_time">_NORTC_MON, _NORTC_MDAY, _NORTC_YEAR</h4>
+<p>This set of options defines the time to be used at no RTC systems. This option has no effect at read-only configuration or <tt>_FS_NORTC = 0</tt>.</p>
+
+<h4 id="fs_lock">_FS_LOCK</h4>
+<p>This option switches file lock function to control duplicated file open and illegal operations to open objects. Note that the file lock function is independent of re-entrancy. This option must be 0 at read-only configuration.</p>
+<table class="lst1">
+<tr><th>Value</th><th>Description</th></tr>
+<tr><td>0</td><td>Disable file lock function. To avoid collapsing file by wrong file operation, application program needs to avoid illegal open, remove and rename to the open objects.</td></tr>
+<tr><td>&gt;0</td><td>Enable file lock function. The value defines how many files/sub-directories can be opened simultaneously under the file lock control. Illigal operations to the open object will be rejected with <tt>FR_LOCKED</tt>.</td></tr>
+</table>
+
+<h4 id="fs_reentrant">_FS_REENTRANT</h4>
+<p>Disable (0) or Enable (1). This option switches the re-entrancy (thread safe) of the FatFs module itself. Note that file/directory access to the different volume is always re-entrant and it can work simultaneously regardless of this option but volume control functions. <tt>f_mount</tt>, <tt>f_mkfs</tt> and <tt>f_fdisk</tt>, are always not re-entrant. Only file/directory access to the same volume, in other words, exclusive use of each file system object, is under control of this function. To enable this feature, also user provided synchronization handlers, <tt>ff_req_grant</tt>, <tt>ff_rel_grant</tt>, <tt>ff_del_syncobj</tt> and <tt>ff_cre_syncobj</tt>, need to be added to the project. Sample code is available in <tt>option/syscall.c</tt>.</p>
+
+<h4 id="fs_timeout">_FS_TIMEOUT</h4>
+<p>Number of time ticks to abort the file function with <tt>FR_TIMEOUT</tt> when wait time is too long. This option has no effect when <tt>_FS_REENTRANT = 0</tt>.</p>
+
+<h4 id="sync_t">_SYNC_t</h4>
+<p>This option defines O/S dependent sync object type. e.g. <tt>HANDLE</tt>, <tt>ID</tt>, <tt>OS_EVENT*</tt>, <tt>SemaphoreHandle_t</tt> and etc. A header file for O/S definitions needs to be included somewhere in the scope of <tt>ff.c</tt>. This option has no effect when <tt>_FS_REENTRANT = 0</tt>.</p>

+<h4>Description</h4>
+<p>The data read/write operation to the storage devices is done in unit of <em>sector</em>. FatFs supports the sector size in range of from 512 to 4096 bytes. When FatFs is configured to fixed sector size (<tt>_MIN_SS == MAX_SS</tt>, this will be the most case), the read/write function must work at that sector size. When FatFs is configured to variable sector size (<tt>_MIN_SS != MAX_SS</tt>), sector size is inquired with <tt>disk_ioctl</tt> function following <tt>disk_initialize</tt> function.</p>
+<p>The memory address specified by <tt class="arg">buff</tt> is not that always aligned to word boundary because the argument is defined as <tt>BYTE*</tt>. The unaligned read/write request can occure at <a href="appnote.html#fs1">direct transfer</a>. If the bus architecture, especially DMA controller, does not allow unaligned memory access, it should be solved in this function. There are some workarounds described below to avoid this issue.</p>
+<ul>
+<li>Convert word transfer to byte transfer in this function if needed. - Recommended.</li>
+<li>On the <tt>f_read</tt> calls, avoid long read request that includes a whole of sector. - Any direct transfer never occures.</li>
+<li>On the <tt>f_read</tt> calls, make sure that <tt>(((UINT)data &amp; 3) == (f_tell(fp) &amp; 3))</tt> is true. - Word alignment of <tt>buff</tt> is guaranteed.</li>
+</ul>
+<p>Generally, a multiple sector transfer request must not be split into single sector transactions to the storage device, or you will not get good read throughput.</p>

+<p>The specified memory address is not that always aligned to word boundary because the type of pointer is defined as <tt>BYTE*</tt>. For more information, refer to the description of <a href="dread.html"><tt>disk_read</tt></a> function.</p>
+<p>Generally, a multiple sector transfer request must not be split into single sector transactions to the storage device, or you will never get good write throughput.</p>
+<p>FatFs expects delayed write function of the disk control layer. The write operation to the media does not need to be completed when return from this function by what write operation is in progress or data is only stored into the write-back cache. But write data on the <tt class="arg">buff</tt> is invalid after return from this function. The write completion request is done by <tt>CTRL_SYNC</tt> command of <tt><a href="dioctl.html">disk_ioctl</a></tt> function. Therefore, if a delayed write function is implemented, the write throughput will be improved.</p>

+<h4>Description</h4>
+<p>The <tt>f_expand</tt> function prepares or allocates a contiguous data area to the file. When <tt class="arg">opt</tt> is 1, the function allocates a contiguous data area to the file. Unlike expansion of file by <tt>f_lseek</tt> function, the file must be truncated prior to use this function and read/write pointer of the file stays at top of the file after the function. The file content allocated with this function is <em>undefined</em> because no data is written to the file in this process. The function can fail with <tt>FR_DENIED</tt> due to some reasons below.</p>
+<ul>
+<li>No free contiguous space was found.</li>
+<li>Size of the file was not zero.</li>
+<li>The file has been opened in read-only mode.</li>
+<li>Not allowable file size. (&gt;= 4GiB on FAT volume)</li>
+</ul>
+<p>When <tt class="arg">opt</tt> is 0, the function finds a contiguous data area and set it as suggested point for next allocation instead of allocating it to the file. The next cluster allocation is started at top of the contiguous area found by this function. Thus the write file is guaranteed be contiguous and no allocation delay until the size reaches that size at least unless any other changes to the volume is performed.</p>
+<p>The contiguous file would have an advantage at time-critical read/write operations. It reduces some overheads in the file system and the storage media caused by random access due to fragmented file data. Especially, at the exFAT volume, any FAT access for the contiguous file is completely eliminated and storage media will be accessed sequentially.</p>
+<p>Also the contiguous file data can be easily accessed directly via low-level disk functions but it is not recommended in consideration for future compatibility.</p>

+<title>FatFs - Path Names</title>
+</head>
+
+<body>
+<h1>Path Names</h1>
+
+<div class="para doc" id="nam">
+<h3>Format of the path names</h3>
+<p>The format of path name on the FatFs module is similer to the filename specs of DOS/Windos as follows:</p>
+<pre>"[<em>drive</em>:][/]<em>directory</em>/<em>file</em>"</pre>
+<p>The FatFs module supports long file name (LFN) and 8.3 format file name (SFN). The LFN can be used when (<tt><a href="config.html#use_lfn">_USE_LFN</a> != 0</tt>). The sub directories are separated with a \ or / in the same way as DOS/Windows API. Duplicated separators are skipped and ignored. Only a difference is that the logical drive is specified in a numeral with a colon. When drive number is omitted, the drive number is assumed as <em>default drive</em> (drive 0 or current drive).</p>
+<p>Control characters (<tt>'\0'</tt> to <tt>'\x1F'</tt>) are recognized as end of the path name. Leading/embedded spaces in the path name are valid as a part of the name at LFN configuration but the space is recognized as end of the path name at non-LFN configuration. Trailing spaces and dots are ignored at both configurations.</p>
+<p>In default configuration (<tt><a href="config.html#fs_rpath">_FS_RPATH</a> == 0</tt>), it does not have a concept of current directory like OS oriented file system. All objects on the volume are always specified in full path name that follows from the root directory. Dot directory names (<tt>".", ".."</tt>) are not allowed. Heading separator is ignored and it can be exist or omitted. The default drive is fixed to drive 0.</p>
+<p>When relative path is enabled (<tt>_FS_RPATH &gt;= 1</tt>), specified path is followed from the root directory if a heading separator is exist. If not, it is followed from the current directory of the drive set by <a href="chdir.html">f_chdir</a> function. Dot names are also allowed for the path names. The default drive is the current drive set by <a href="chdrive.html">f_chdrive</a> function.</p>
+<table class="lst2">
+<tr><td>Path name</td><td>_FS_RPATH == 0</td><td>_FS_RPATH &gt;= 1</td></tr>
+<tr class="lst3"><td>file.txt</td><td>A file in the root directory of the drive 0</td><td>A file in the current directory of the current drive</td></tr>
+<tr><td>/file.txt</td><td>A file in the root directory of the drive 0</td><td>A file in the root directory of the current drive</td></tr>
+<tr><td></td><td>The root directory of the drive 0</td><td>The current directory of the current drive</td></tr>
+<tr><td>/</td><td>The root directory of the drive 0</td><td>The root directory of the current drive</td></tr>
+<tr><td>2:</td><td>The root directory of the drive 2</td><td>The current directory of the drive 2</td></tr>
+<tr><td>2:/</td><td>The root directory of the drive 2</td><td>The root directory of the drive 2</td></tr>
+<tr><td>2:file.txt</td><td>A file in the root directory of the drive 2</td><td>A file in the current directory of the drive 2</td></tr>
+<tr><td>../file.txt</td><td>Invalid name</td><td>A file in the parent directory</td></tr>
+<tr><td>.</td><td>Invalid name</td><td>This directory</td></tr>
+<tr><td>..</td><td>Invalid name</td><td>Parent directory of the current directory (*)</td></tr>
+<tr><td>dir1/..</td><td>Invalid name</td><td>The current directory</td></tr>
+<tr><td>/..</td><td>Invalid name</td><td>The root directory (sticks the top level)</td></tr>
+</table>
+<p>When option <tt><a href="config.html#str_volume_id">_STR_VOLUME_ID</a></tt> is specified, also pre-defined strings can be used as drive identifier in the path name instead of a numeral. e.g. <tt>"sd:file1.txt"</tt>, <tt>"ram:swapfile.dat"</tt> and DOS/Windows style drive letter, of course.</p>
+<p><em>Remark: In this revision, double dot name <tt>".."</tt> cannot follow the parent directory on the exFAT volume. It will work as <tt>"."</tt> and stay there.</em></p>
+</div>
+
+<div class="para doc" id="case">
+<h3>Legal Characters and Case Sensitivity</h3>
+<p>On the FAT file system, legal characters for file name are, <tt>0-9 A-Z ! # $ % &amp; ' ( ) - @ ^ _ ` { } ~</tt> and extended characters (<tt>\x80</tt>-<tt>\xFF</tt>). Under LFN supported system, also white space and <tt>+ , ; = [ ]</tt> are legal for the file name and the white spaces and periods can be placed anywhere in the name except for end of the name string.</p>
+<p>FAT file system is case-insensitive to the object names on the volume. All object names are compared in case-insensitive. For example, these three names, <tt>file.txt</tt>, <tt>File.Txt</tt> and <tt>FILE.TXT</tt>, are identical. This is applied to also extended charactres. When an object is created on the FAT volume, upper converted name is recorded to the SFN entry, and the raw name is recorded to the LFN entry.</p>
+<p>As for the DBCS language MS-DOS, it was case-sensitive to the extended characters. To follow this specification, FatFs works with case-sensitive to the extended characters at only non-LFN with DBCS configuration (DOS/DBCS specs). But at LFN configuration, FatFs works with case-insensitive to all characters (WindowsNT specs). This can cause a problem on compatibility with Windows system when an object with extended characters is created on the volume at non-LFN and DBCS configuration; therfore the object names with DBCS extended characters should not be used on the FAT volume shared by those systems.</p>
+</div>
+
+<div class="para doc" id="uni">
+<h3>Unicode API</h3>
+<p>The path names are input/output in either ANSI/OEM code or Unicode depends on the configuration options. The type of arguments which specify the path names are defined as <tt>TCHAR</tt>. It is an alias of <tt>char</tt> by default. The code set used to the path name string is ANSI/OEM specifid by <tt><a href="config.html#code_page">_CODE_PAGE</a></tt>. When <tt><a href="config.html#lfn_unicode">_LFN_UNICODE</a></tt> is set to 1, the type of the <tt>TCHAR</tt> is switched to <tt>WCHAR</tt> to support Unicode (UTF-16 encoding). In this case, the full-featured LFN specification is supported and the Unicode specific characters, such as ✝☪✡☸☭, can also be used for the path name. It also affects data types and encoding of the string I/O functions. To define literal strings, <tt>_T(s)</tt> and <tt>_TEXT(s)</tt> macro are available to select either ANSI/OEM or Unicode automatically. The code shown below is an example to define the literal strings.</p>
+<pre>
+ f_open(fp, "filename.txt", FA_READ);      <span class="c">/* ANSI/OEM string */</span>
+ f_open(fp, L"filename.txt", FA_READ);     <span class="c">/* Unicode string */</span>
+ f_open(fp, _T("filename.txt"), FA_READ);  <span class="c">/* Changed by configuration */</span>
+</pre>
+</div>
+
+<div class="para doc" id="vol">
+<h3>Volume Management</h3>
+<p>FatFs module needs dynamic work area, <em>file system object</em>, for each volume (logical drive). It is registered/unregistered to the FatFs module by <tt>f_mount</tt> function. By default, each logical drive is bound to the physical drive with the same drive number and an FAT volume on the drive is serched by the volume mount process. It reads boot sectors and checks it if it is an FAT boot sector in order of sector 0 as SFD format, 1st partition, 2nd partition, 3rd partition and 4th partition as FDISK format.</p>
+<p>When <tt><a href="config.html#multi_partition">_MULTI_PARTITION</a> == 1</tt> is specified by configuration option, each individual logical drive is bound to the partition on the physical drive specified by volume management table. The volume management table must be defined by user to resolve the relationship between logical drives and partitions. Following code is an example of a volume management table.</p>
+<pre>
+Example: Logical drive 0-2 are tied to three pri-partitions on the physical drive 0 (fixed drive)
+         Logical drive 3 is tied to an FAT volume on the physical drive 1 (removable drive)
+
+PARTITION VolToPart[] = {
+    {0, 1},     <span class="c">/* "0:" ==> Physical drive 0, 1st partition */</span>
+    {0, 2},     <span class="c">/* "1:" ==> Physical drive 0, 2nd partition */</span>
+    {0, 3},     <span class="c">/* "2:" ==> Physical drive 0, 3rd partition */</span>
+    {1, 0}      <span class="c">/* "3:" ==> Physical drive 1, auto detection */</span>
+};
+</pre>
+<div><img src="../res/f7.png" width="828" height="288" alt="relationship between logical drive and physical drive"></div>
+<p>There are some considerations on using multi-partition configuration.</p>
+<ul>
+<li>The physical drive that has two or more mounted partitions must be non-removable. Media change while a system operation is prohibited.</li>
+<li>Only four primary partitions can be specified. Extended partition is not supported.</li>
+<li>Windows does not support multiple volumes on the removable storage. Only first parition will be recognized.</li>
+</ul>

+<h4>Description</h4>
+<p>The <tt>f_lseek</tt> function moves the file read/write pointer of an open file. The offset can be specified in only origin from top of the file. When an offset beyond the file size is specified at write mode, the file size is expanded to the specified offset. The file data in the expanded area is <em>undefined</em> because no data is written to the file in this process. This is suitable to pre-allocate a cluster chain quickly, for fast write operation. When a contiguous data area needs to be allocated to the file, use <tt>f_expand</tt> function instead. After the <tt>f_lseek</tt> function succeeded, the current read/write pointer should be checked in order to make sure the read/write pointer has been moved correctry. In case of the read/write pointer is not the expected value, either of followings has been occured.</p>
+<ul>
+<li>End of file. The specified <tt class="arg">ofs</tt> was clipped at end of the file because the file has been opened in read-only mode.</li>
+<li>Disk full. There is no free space on the volume to expand the file.</li>
+</ul>
+<p>The fast seek function enables fast backward/long seek operations without FAT access by using an on-memory CLMT (cluster link map table). It is applied to <tt>f_read</tt> and <tt>f_write</tt> function as well, however, the file size cannot be expanded by <tt>f_write</tt>, <tt>f_lseek</tt> function while the file is in fast seek mode.</p>
+<p>The fast seek function is enabled when the member <tt>cltbl</tt> in the file object is not NULL. The CLMT must be created into the <tt>DWORD</tt> array prior to use the fast seek function. To create the CLMT, set address of the <tt>DWORD</tt> array to the member <tt>cltbl</tt> in the open file object, set the size of array in unit of items to the first item and call the <tt>f_lseek</tt> function with <tt class="arg">ofs</tt><tt> = CREATE_LINKMAP</tt>. After the function succeeded and CLMT is created, no FAT access is occured in subsequent <tt>f_read</tt>, <tt>f_write</tt>, <tt>f_lseek</tt> function to the file. The number of items used or required is returned into the first item of the array. The number of items to be used is (number of the file fragments + 1) * 2. For example, when the file is fragmented in 5, 12 items in the array will be used. If the function failed with <tt>FR_NOT_ENOUGH_CORE</tt>, the given array size is insufficient for the file.</p>

+<h4>Description</h4>
+<p>The FAT sub-type, FAT12/FAT16/FAT32, of FAT volume except exFAT is determined by only number of clusters on the volume and nothing else, according to the FAT specification issued by Microsoft. Thus which FAT sub-type is selected, is depends on the volume size and the specified cluster size. In case of the combination of FAT type and cluter size specified by argument cannot be valid on the volume, the function will fail with <tt>FR_MKFS_ABORTED</tt>.</p>
+<p>The allocation unit, also called 'cluster', is a unit of disk space allocation for files. When the size of allocation unit is 32768 bytes, a file with 100 bytes in size occupies 32768 bytes of disk space. The space efficiency of disk usage gets worse as increasing size of allocation unit, but, on the other hand, the read/write performance increases as the size of allocation unit. Therefore the allocation unit is a trade-off between space efficiency and performance. For the large storages in GB order, 32768 bytes or larger cluster (this is automatically selected by default) is recommended for most case unless extremely many files are created on a volume.</p>
+<p>There are two disk formats, FDISK and SFD. The FDISK format is usually used for harddisk, MMC, SDC, CFC and U Disk. It can divide a physical drive into one or more partitions with a partition table on the MBR (maser boot record, the first sector of the physical drive). The SFD (super-floppy disk) is non-partitioned disk format. The FAT volume starts at the first sector of the physical drive without any disk partitioning. It is usually used for floppy disk, Microdrive, optical disk and most type of super-floppy media. Some systems support only either one of two formats and other is not supported.</p>
+<p>When <tt>FM_SFD</tt> is not specified, a primary partition occupies whole drive space is created and then the FAT volume is created in it. When <tt>FM_SFD</tt> is specified, the FAT volume occupies from the first sector of the drive is created.</p>
+<p>If the logical drive to be formatted is bound to the specific partition (1-4) by support of multiple partition, <tt><a href="config.html#multi_partition">_MULTI_PARTITION</a></tt>, the FAT volume is created into the partition and <tt>FM_SFD</tt> flag is ignored. The physical drive needs to be partitioned with <tt>f_fdisk</tt> function or any other partitioning tools prior to create the FAT volume with this function.</p>

The volume mount process will be attempted at subsequent file access functions if the file system object is not initialized. (delayed mounting)</p>
+<p>If implementation of the disk I/O layer lacks media change detection, application program needs to perform a <tt>f_mount</tt> function after each media change to force cleared the file system object.</p>

+<h4>Description</h4>
+<p>The <tt>f_readdir</tt> function reads a directory item, informations about the object. All items in the directory can be read in sequence by <tt>f_readdir</tt> function calls. Dot entries (<tt>"."</tt> and <tt>".."</tt>) in the sub-directory are filtered out and they will never appear in the read items. When all directory items have been read and no item to read, a nul string is stored into the <tt>fno-&gt;fname[]</tt> without any error. When a null pointer is given to the <tt class="arg">fno</tt>, the read index of the directory object is rewinded.</p>
+<p>When support of long file name (LFN) is enabled, a member <tt>altname[]</tt> is defined in the file information structure to store the short file name of the object. In case of the some conditions listed below, short file name is stored into the <tt>fname[]</tt> and <tt>altname[]</tt> has a null string.</p>
+<ul>
+<li>The item has no long file name. (Not the case at exFAT volume)</li>
+<li>Setting of <tt>_MAX_LFN</tt> is insufficient for the long file name. (Not the case at <tt>_MAX_LFN == 255</tt>)</li>
+<li>The long file name contains any character not allowed in ANSI/OEM code. (Not the case at <tt>_LFN_UNICODE == 1</tt>)</li>
+</ul>
+<p>There is a problem on reading a directory of exFAT volume. The exFAT does not support short file name. This means no name can be returned on the condition above. If it is the case, a "?" is returned as file name to indicate that the object is not accessible. To avoid this problem, configure FatFs <tt>_LFN_UNICODE = 1</tt> and <tt>_MAX_LFN = 255</tt> to support the full feature of LFN specification.</p>

+<li>Spaces can be contained anywhere in the volume label. Trailing spaces are truncated off at FAT volume.</li>
+<li>Period is not allowed.</li>
+<li>Up to 11 bytes long as conversion of OEM code page at FAT volume.</li>
+<li>Up to 11 characters long at exFAT volume. Case information is preserved.</li>
+</ul>
+<p>Remark: The standard system (Windows) has a problem at handling of the volume label with a heading <tt>\xE5</tt> on the FAT volume. To avoid this problem, this function rejects such volume label as invalid name.</p>

+<h4>Description</h4>
+<p>The <tt>f_sync</tt> function performs the same process as <tt>f_close</tt> function but the file is left opened and can continue read/write/seek operations to the file. This is suitable for the applications that open files for a long time in write mode, such as data logger. Performing <tt>f_sync</tt> function of periodic or immediataly after <tt>f_write</tt> function can minimize the risk of data loss due to a sudden blackout or an unintentional media removal. For more information, refer to <a href="appnote.html#critical">application note</a>.</p>
+<p>However there is no sense in <tt>f_sync</tt> function immediataly before <tt>f_close</tt> function because it performs <tt>f_sync</tt> function in it. In other words, the differnce between those functions is that the file object is invalidated or not.</p>

+<h3>ポーティングの際に配慮すべきこと</h3>
+
+<h4>ポーティングの際の前提条件</h4>
+<p>FatFsモジュールはポータビリティに関して次の点を前提としています。</p>
+<ul>
+<li>処理系はANSI C準拠であること。<br>
+FatFsモジュールはANSI C(C89)準拠で記述されているので、普通のCコンパイラなら特に処理系依存になる点はありません。</li>
+<li>char/short/longのサイズは、それぞれ8/16/32ビットで、intは16または32ビットであること。<br>
+これについても、まっとうな処理系なら問題ないはずです。FatFsモジュールで使用されるサイズを明示する整数型が integer.h 内で定義されていますが、既存の定義と衝突した場合はユーザによって解決されなければなりません。</li>
+</ul>
+
+<h4>システム構成</h4>
+<p>下に示す依存関係図は、FatFsモジュール利用の組み込みシステムにおける代表的な構成を示します。</p>
+<p><img src="../res/modules.png" width="580" height="280" alt="システム構成図"></p>
+<p>(a) FatFs用に書かれたディスク モジュールがある場合は、そのまま追加するだけです。 (b) しかし、多くの既存のディスク モジュールはそのAPIをFatFsに合わせるため、グルー関数が必要になるでしょう。</p>
+<p><img src="../res/funcs.png" width="750" height="420" alt="functional diagram"></p>
+
+<h4>ユーザの作成する関数</h4>
+<p>ポーティング作業は、要求されるデバイス制御関数を用意することが全てで、それ以外にすることは何もありません。既に動作しているデバイス制御モジュールがあるなら、そのインターフェースをFatFsに合わせるかグルー関数を介してつなぐだけで済みますが、無い場合はほかから移植するか最初から書くかする必要があります。定義されている全ての関数が常に必要なわけではありません。例えば、リード オンリ構成では書き込み系関数は必要ありません。次の表に構成オプションと要求される関数の対応を示します。</p>
+<table class="lst2">
+<tr><th>必要な関数</th><th>必要となる条件</th><th>備考</th></tr>
+<tr><td>disk_status<br>disk_initialize<br>disk_read</td><td>常時</td><td rowspan="5">ffsample.zip (サンプル)<br>その他web上に多数</td></tr>
+<tr><td>disk_write<br>get_fattime<br>disk_ioctl (CTRL_SYNC)</td><td>_FS_READONLY == 0</td></tr>
+<tr><td>disk_ioctl (GET_SECTOR_COUNT)<br>disk_ioctl (GET_BLOCK_SIZE)</td><td>_USE_MKFS == 1</td></tr>

+<h3>長いファイル名</h3>
+<p>FatFsモジュールは、長いファイル名(LFN)をサポートします。ファイルに付けられた2つの異なる名前(短いファル名と長いファイル名)は、<tt>f_readdir</tt>関数を除くファイル操作関数において透過です。デフォルト構成では、LFN機能はOFFになっています。LFN機能を有効にするには、<tt><a href="config.html#use_lfn">_USE_LFN</a></tt>を1,2または3に設定し、<tt>option/unicode.c</tt>をプロジェクトに追加します。LFN機能は、加えてある程度のワーク エリア(LFN操作バッファ)を必要とします。バッファ長は使用できるメモリに応じて<tt><a href="config.html#max_lfn">_MAX_LFN</a></tt>で構成されることができます。LFNの長さは最大255文字に達するので、LFN完全対応のためには<tt>_MAX_LFN</tt>は255に設定されるべきです。与えられたファイル名に対してバッファ長が不足した場合、ファイル関数は<tt>FR_INVALID_NAME</tt>で失敗します。</p>
+<p>ファイル関数に再入を行う条件の下でLFN機能を使用する場合は、<tt>_USE_LFN</tt>は2または3に設定されなければなりません。この場合、ファイル関数はワーク エリアを動的に確保(スタックまたはヒープ)します。ワーク エリアのサイズは、<tt>(_MAX_LFN + 1) * 2</tt>バイト(exFAT利用時はさらに+608バイト)になるので、スタック等のサイズはそれを考慮した十分な余裕がなければなりません。</p>

+<p>LFN機能の上手な使い方は、それを使わないということです。実際、組み込み用途ではLFN機能がどうしても必要になるということはほとんど無いはずです。LFNを有効にすると、選択されたコード ページに応じてモジュール サイズが増大します。右の表に各コード ページにおけるLFNを有効にしたときのモジュール サイズの違いを示します。特に、CJK地域では数万の文字が使われていますが、不幸なことにそれは巨大なOEM－Unicode相互変換テーブルを要求し、モジュール サイズは劇的に増大します。その結果、それらのコード ページにおいてLFNを有効にしたFatFsモジュールは、多くの8ビット マイコンにインプリメントすることができません。</p>
+<p>LFN機能のハードルはそれだけではありません。マイクロソフト社はFATファイルシステムについていくつかの特許を保有しています。いずれもLFN機能の実装に関するもので、その利用に対して$0.25/unitのライセンス料を要求しています。このため、商用製品でLFN機能を利用する場合は、製品の最終仕向地によってはライセンスが必要になります。最近のFAT32ドライバの多くはLFN機能を含んでいるため、それらの使用に当たってライセンスが必要になりますが、FatFsは構成オプションでLFN機能を任意にON/OFFできるため、無効にしてライセンス問題を回避することもできます。</p>

+<h3>exFATファイルシステム</h3>
+<p>exFAT(Microsoft's Extended File Allocation Table)ファイルシステムは、既に組み込みシステムや情報家電で広く使われているFATファイルシステムを置き換える目的で開発されました。exFATは、64GiB以上のSDメモリ カードで標準ファイルシステムに採用されるなど、FATに並びリムーバブル メディアの標準ファイルシステムの一つとなりつつあります。</p>
+<p>exFATボリュームでは、FATボリュームで制約となっていた4GiB以上のサイズのファイルを扱え、ファイルシステムのオーバーヘッド(特にファイル アロケーション ディレイ)も大幅に低減され、書き込みスループットがFATより向上しています。しかし、現リビジョンのFatFsでは、実装上の理由から不連続ファイルへのサイズ拡大を伴う書き込み時のとき、スループットがFATより低下します。<tt>f_expand</tt>関数による連続領域の割り当て機能は、この問題の回避に有効かもしれません。</p>
+<p>exFATはマイクロソフト社が開発したものなので、マイクロソフト社はexFATについていくつかの特許を保有しています。FatFsのexFAT機能は、それの US. Pat. App. Pub. No. 2009/0164440 A1 に基づいた実装です。このため、商用製品でexFAT機能を利用する場合、製品の最終仕向地によってはライセンスが必要になります。最近のFATドライバの多くはexFAT機能を含んでいるため、それらの使用に当たってライセンスが必要になりますが、FatFsは構成オプションでexFAT機能を任意にON/OFFできるため、無効にしてライセンス問題を回避することもできます。</p>

+<h3>リエントランシー</h3>
+<p>互いに異なるボリュームに対するファイル操作は、<tt>_USE_LFN == 1</tt>を除いて構成にかかわらずリエントラントで、常に同時平行に動作できます。</p>
+<p>同じボリュームに対してはデフォルトではリエントラントではありませんが、<tt><a href="config.html#fs_reentrant">_FS_REENTRANT</a></tt>でリエントラント(スレッド セーフ)にすることはできます。この場合、OS依存の同期オブジェクト操作関数<tt>ff_cre_syncobj, ff_del_syncobj, ff_req_grant, ff_rel_grant</tt>関数もまたプロジェクトに追加されなければなりません。サンプル コードと解説は<tt>option/syncobj.c</tt>にあります。</p>
+<p>この場合、あるタスクがボリュームを使用中に他のタスクからそのボリュームに対するファイル関数が呼び出されると、そのアクセスは先のタスクがファイル関数を抜けるまでサスペンドされます。待ち時間が<tt>_TIMEOUT</tt>で指定された期間を越えた場合、その関数は<tt>FR_TIMEOUT</tt>でアボートします。いくつかのRTOSではタイムアウト機能はサポートされないかも知れません。</p>
+<p>ひとつの例外が<tt>f_mount, f_mkfs, f_fdisk</tt>関数にあります。これらのボリューム制御関数は同じボリューム(または関連する物理ドライブ)に対してリエントラントではありません。これらの関数を使用するときは、アプリケーション レベルで排他制御しなければなりません。</p>
+<p>注: このセクションはFatFsモジュールそれ自体のリエントランシーについて説明しています。<tt>_FS_REENTRANT</tt>は、各ファイルシステム オブジェクトの排他制御を行うのみで、下位のディスク関数への再入を防止するものではありません。たとえば、シングル ボリューム構成では<tt>disk_status</tt>関数のみ再入される可能性があり、マルチ ボリューム構成ではどのディスク関数も再入される可能性があります。このように、複数のタスクから同時にFatFs APIを使う条件では、ディスクI/Oモジュールはスレッド セーフである必要があります。</p>

+<p><tt><a href="config.html#fs_lock">_FS_LOCK</a></tt>に1以上の値(値は同時に管理できるファイル数)をセットすることで多重アクセス制御機能が有効になり、ファイル単位のアクセス制御を自動で行うこともできます。この場合、上記のルールを破ったオープン・リネーム・削除を試みると、その関数は<tt>FR_LOCKED</tt>で失敗します。また、<tt>_FS_LOCK</tt>を越える数のファイルやサブ ディレクトリを同時にオープンしようとすると、<tt>FR_TOO_MANY_OPEN_FILES</tt>で失敗します。</p>

+<p>図1はセクタの一部のデータがファイルI/Oバッファを経由で転送されることを示します。図2に示される長いデータの転送では、転送データの中間の1セクタまたはそれ以上のセクタにまたがる転送データがアプリケーション バッファに直接転送されています。図3は転送データ全体がセクタ境界にアライメントされている場合を示しています。この場合、ファイルI/Oバッファは使用されません。直接転送においては最大の範囲のセクタが<tt>disk_read</tt>関数で一度に読み込まれますが、クラスタ境界を越えるマルチ セクタ転送はそれが隣接であっても行われません。</p>
+<p>このように、セクタにアライメントしたファイルの読み書きへの配慮はバッファ経由のデータ転送を避け、読み書き性能は改善されるでしょう。その効果に加え、タイニー構成でキャッシュされたFATデータがファイル データの転送によりフラッシュされず、非タイニー構成と同じ性能を小さなメモリ フットプリントで達成できます。</p>

+<h3>フラッシュ メモリの特性への配慮</h3>
+<p>HDDなどのディスク メディアとは異なり、SDCやCFCなどのフラッシュ メモリ メディアの性能を引き出すには、その特性を意識した制御が必要になります。</p>
+<h4>マルチ セクタ書き込み</h4>
+<div class="rset">
+図6. マルチ/シングル セクタ ライトの比較<br>
+<img src="../res/f6.png" width="630" height="148" alt="fig.6">
+</div>
+<p>フラッシュ メモリ メディアの書き込み速度はシングル セクタ書き込みの時に最も低いものになり、一回のトランザクションで転送されるセクタ数が大きくなるほど書き込み速度は向上します(図6)。この効果はバス速度が高速になるほど大きく、10倍以上の差が現れることも珍しくありません。<a href="../res/rwtest2.png">テスト結果</a>は、マルチ セクタ書き込み(W:16K, 32 sectors)がシングル セクタ書き込み(W:100, 1 sector)よりどの程度速いかを明確に示しています。大容量メディアほどシングル セクタ書き込みが遅くなる点もまた重要です。書き込みトランザクションの回数はまた、メディアの寿命にも影響してきます。つまり、同じ量のデータを書き込む場合、図6上のシングル セクタ書き込みは、図6下のマルチ セクタ書き込みに比べて16倍早くフラッシュ メモリ メディアを消耗させてしまうということです。</p>
+<p>このように、アプリケーションはなるべく大きなブロック(クラスタ サイズまたは2の累乗セクタ境界にアライメントした)で読み書きを行う必要があります。もちろん、アプリケーションからメディアに至る全てのレイヤがマルチ セクタ転送に対応していないと意味がありません。残念ながら、既存のオープン ソースのドライバの多くはマルチ セクタ転送に未対応です。なお、FatFsモジュールおよびサンプル ドライバはマルチ セクタ転送に対応しています。</p>
+<h4>明示的なメモリ消去</h4>
+<p>通常のファイル消去では、記録されたデータに対して何らかの処理が行われるわけではなく、単にFAT上にその領域を未使用と記録しているだけです。このため、ファイルが消去されたあともそれらは有効なデータ ブロックとしてフラッシュ メモリ上に残ります。そこで、ファイルを消去するとき、占有していたデータ セクタを明示的に消去(つまり未使用ブロックにする)することにより、メディア内の空きブロックを増やすことができます。これにより、次にそのブロックに書き込むときの消去動作が無くなり、書き込み性能が向上する可能性があります。また、ウェアレベリングに使えるブロックが増え、メディアの耐久性も向上するかも知れません。この機能を有効にするには、<tt><a href="config.html#use_trim">_USE_TRIM</a></tt>に1を設定します。これはフラッシュ メモリ ドライブの内部動作に期待した制御なので、効果があるとは限りません。また、ファイル消去の時間が延びることも考慮に入れるべきです。</p>
+</div>
+
+<div class="para doc" id="critical">
+<h3>クリチカル セクション</h3>
+<p>ストレージ上のFAT構造を操作している途中で、停電、不正なメディアの取り外し、回復不能なデータ エラー等の障害が発生すると、処理が中途半端な状態で中断され、その結果としてFATボリュームの構造が破壊される可能性があります。次にFatFsモジュールにおけるクリチカル セクションと、その間の障害により起きうるエラーの状態を示します。</p>

+<br class="clr">
+<p>赤で示したセクションを実行中に中断が発生した場合、クロス リンクが発生して操作中のファイルやディレクトリが失われる可能性があります。黄色で示したセクションを実行中に中断が発生した場合、次のうちいずれかまたは複数の結果が生じる可能性があります。</p>
+<ul>
+<li>ファイルの一部を書き換え中: 書き換えが中途半端な状態となり、結果データが破壊される。</li>
+<li>追記モードでデータ記録中: ファイルが記録開始の前の状態に戻る。</li>

+<li>新規または上書きで作成したファイルに記録中: ファイルの長さがゼロになって残る。</li>
+<li>これらの障害の結果、ロスト クラスタが発生してボリュームの利用効率が悪化する。</li>
+</ul>
+<p>いずれの場合も操作の対象でないファイルには影響はありません。これらのクリチカル セクションは、ファイルを書き込みモードで開いている時間を最小限にするか、<tt>f_sync</tt>関数を適宜使用することで図5のようにリスクを最小化することができます。</p>

+<h3>FatFsのライセンスについて</h3>
+<p>FatFsは、作者(ChaN)の個人プロジェクトとして開発されています。現在までのリビジョンにおいてコントリビューターはいないため、作者以外の書いたソース コードは含まれません。ソース ファイルにライセンス条件が記述されているので、利用の際はそれに従うこと。原文は英語ですが、参考までに以下に日本語訳を示しておきます。</p>
+<pre>
+/*----------------------------------------------------------------------------/
+/  FatFs - Generic FAT file system module  R0.12a                             /

+/ Copyright (C) 2016, ChaN, all right reserved.
+/
+/ FatFsモジュールはオープンソースソフトウェアです。FatFsの再配布および使用は、
+/ ソースコードかバイナリ形式か、また変更の有無にかかわらず、次の条件が満たされ
+/ る場合に限り許可されます。
+/
+/ 1. ソースコードで再配布するときは、その中に上記の著作権表示、この条件、および

+/----------------------------------------------------------------------------*/
+</pre>
+<p>このようにFatFsはBSDライクなライセンスとしていますが、一つ大きな違いがあります。FatFsは主に組み込み向けとして開発されたため、バイナリ形式(ソース コードを含まない形式全て)での再配布については、商用での使いやすさを考慮して配布時の条件を設けていません。つまり、バイナリ配布の場合は、FatFsおよびそのライセンス文書についてドキュメントに明記してもしなくてもかまいません。これは、一条項BSDライセンスと等価ということです。もちろん、GNU GPLなどほとんど全てのオープン ソース ライセンスの下のプロジェクトにおいて共存可能です。FatFsからフォークを作成し公開する場合は、矛盾しない他のオープン ソース ライセンス(GNU GPLや修正BSDライセンスなど)に変更することも可能です。</p>

+<p>ボリュームID文字列を定義します。<tt>_VOLUMES</tt>で設定された個数の文字列を<tt>"RAM","SD","CF",...</tt> のように挙列します。使用可能な文字はA～Zおよび0～9で、先頭の項目が論理ドライブ0に対応します。</p>
+
+<h4 id="multi_partition">_MULTI_PARTITION</h4>
+<p>マルチ区画機能の設定(0:無効 または 1:有効)。無効のときは、個々の論理ドライブは同じ番号の物理ドライブに1:1で対応し、それぞれの物理ドライブ中の最初の区画に結びつけられます。マルチ区画機能を有効にすると、論理ドライブはそれぞれ任意の物理ドライブの任意の区画に結びつけることができます。マッピングは、ユーザ定義の変換テーブル<tt>VolToPart[]</tt>によって行います。また、<tt>f_fdisk</tt>関数が利用可能になります。詳しくは、<a href="filename.html#vol">こちら</a>を参照してください。</p>
+
+<h4 id="max_ss">_MIN_SS、_MAX_SS</h4>

+<p>exFATのサポート(0:使用しない または 1:使用する)。exFATを使用するには、LFN機能を有効にしなければなりません。また、exFATの完全サポートのためには、<tt>_LFN_UNICODE = 1</tt>と<tt>_MAX_LFN = 255</tt>の設定が推奨されます。exFAT機能では64ビット整数を使用するため、これを有効にするとC89(ANSI C)互換が失われます。</p>
+
+<h4 id="fs_nortc">_FS_NORTC</h4>
+<p>RTC機能の使用の設定(0:使用する または 1:使用しない)。システムがRTC(カレンダ時計)をサポートしない場合は、1をセットします。この場合、FatFsが変更を加えたオブジェクトのタイムスタンプはデフォルトの日時を持ちます。RTCが使用可能なときは、0を設定し、<tt>get_fattime</tt>関数をプロジェクトに加えます。リード オンリ構成ではこのオプションは意味を持ちません。</p>

+</table>
+
+<h4 id="fs_reentrant">_FS_REENTRANT</h4>
+<p>リエントランシーの設定(0:無効 または 1:有効)。このオプションは、FatFsモジュール自体のリエントランシー(スレッド セーフ)の設定をします。異なるボリュームに対するファイル アクセスはこのオプションに関係なく常にリエントラントで、<tt>f_mount</tt>、<tt>f_mkfs</tt>、<tt>f_fdisk</tt>などのボリューム操作関数はこのオプションに関係なく常にリエントラントではありません。同じボリュームに対するファイル アクセス(つまり、ファイル システム オブジェクトの排他使用)のみがこのオプションの制御下にあります。このオプションを有効にしたときは、同期関数である<tt>ff_req_grant</tt>、<tt>ff_rel_grant</tt>、<tt>ff_del_syncobj</tt>、<tt>ff_cre_syncobj</tt>をプロジェクトに追加する必要があります。サンプルが<tt>option/syscall.c</tt>にあります。</p>

+<h4 id="fs_timeout">_FS_TIMEOUT</h4>
+<p>タイムアウト時間の設定。待ち合わせ時間が長いときに<tt>FR_TIMEOUT</tt>でファイル関数をアボートする時間を設定します。<tt>_FS_REENTRANT</tt>が0のときは意味を持ちません。</p>
+
+<h4 id="sync_t">_SYNC_t</h4>
+<p>O/S定義の同期オブジェクトの型を設定します。例: <tt>HANDLE</tt>、<tt>ID</tt>、<tt>OS_EVENT*</tt>、<tt>SemaphoreHandle_t</tt>など。また、O/S機能のヘッダ ファイルを<tt>ff.c</tt>のスコープ内にインクルードする必要があります。<tt>_FS_REENTRANT</tt>が0のときは意味を持ちません。</p>

+<h4>解説</h4>
+<p>ストレージ デバイスに対するデータの読み書きは、セクタ単位で行われます。FatFsでは512～4096バイトのセクタ サイズをサポートします。固定セクタ サイズ構成(<tt>_MIN_SS == MAX_SS</tt>)のときは、暗黙的にそのセクタ サイズで動作しなければなりません。可変セクタ サイズ構成(<tt>_MIN_SS &lt; MAX_SS</tt>)のときは、<tt>disk_initialize</tt>関数に続いて<tt>disk_ioctl</tt>関数でセクタ サイズを問い合わせてくるので、それに対して正しい値を返す必要があります。</p>
+<p><tt class="arg">buff</tt>は<tt>BYTE</tt>型なので、指定されるアドレスは<em>常にワード アライメントされているとは限りません</em>。非アライメント アドレスへの転送は、<a href="appnote.html#fs1">直接転送</a>において発生することがあります。もしも、ハードウェア上の制約でそのような転送が不可能なときは、この関数内で二段転送するなどして解決するか、または別の方法で対応しなければなりません。次にいくつかの対応方法を示します(いずれか一つでOK)。</p>
+<ul>
+<li>この関数内で解決する - 推奨</li>
+<li>全ての<tt>f_read()</tt>において、セクタ全体を含む転送を避ける - 直接転送が発生しない</li>
+<li><tt>f_read(fp, data, btr, &amp;br)</tt>において、<tt>(((UINT)data &amp; 3) == (f_tell(fp) &amp; 3))</tt>を満足させる - 直接転送での<tt class="arg">buff</tt>のワード アライメントが保証される</li>
+</ul>
+<p>一般的に、複数セクタの転送要求は、ストレージ デバイスに対して可能な限りマルチ セクタ転送しなければなりません。複数のシングル セクタ読み出しに分解された場合、スループットが低下することがあります。</p>

+<li>ファイルのサイズが0ではなかった。</li>

+<li>指定されたファイル サイズが無効。(FATボリューム上で &gt;=4GiB)</li>
+</ul>
+<p><tt class="arg">opt</tt>に0を指定したときは、連続したデータ領域を探すのみで、その時点ではファイルへの割り当てを行わず、代わりにそれを検索開始ポイントとしてファイル システム オブジェクトにセットします。これにより、そのボリューム上で別の操作(FAT変更を伴う)が行われない限り、書き込まれるファイルは少なくともそのサイズまでは連続性が保証され、遅延無く書き込めることになります。</p>
+<p>時間的制約のあるファイル読み書き操作において、連続データ領域を割り当てられたファイルは有利となります。これは、分割されたファイルによりもたらされる無用なランダム アクセスが減ることにより、ファイル システムやストレージ デバイスの処理のオーバーヘッドが削減されるからです。特にexFATボリューム上の連続ファイルでは一切のFATアクセスが発生せず、効率的なシーケンシャル アクセスが行えます。</p>

+<title>FatFs - パス名のフォーマット</title>
+</head>
+
+<body>
+<h1>パス名のフォーマット</h1>
+<div class="para doc" id="nam">
+<h3>ファイル ディレクトリ名</h3>
+<p>FatFsモジュールでは、パス名によるファイル、ディレクトリ、ドライブの指定方法はDOS/Windows APIとほぼ同じです。パス名のフォーマットは次の通りです。</p>
+<pre>"[論理ドライブ番号:][/]ディレクトリ名/ファイル名"</pre>
+<p>FatFsモジュールは長いファイル名(LFN)および8.3形式ファイル名(SFN)に対応しています。LFNは、(<tt><a href="config.html#use_lfn">_USE_LFN</a> &gt; 0</tt>)のとき使用可能になります。ディレクトリ セパレータにはDOS/Windows APIと同じく<tt>'/'</tt>と<tt>'\'</tt>を使用します。連続したセパレータは無視され1個として扱われます。唯一の違いは、論理ドライブの指定だけです。論理ドライブ番号は、<tt>'0'</tt>～<tt>'9'</tt>の一文字の数字とコロンで指定し、省略した場合は<em>デフォルト ドライブ</em>(0またはカレント ドライブ)が選択されます。</p>
+<p>ヌル文字や制御文字(<tt>'\0'</tt>～<tt>'\x1F'</tt>)は、パス名の終端として認識されます。パス名に先行あるいは中に含まれるスペースは、LFN構成では名前の一部として有効ですが、非LFN構成ではスペースはパス名の終端として認識されます。</p>
+<p>標準構成(<tt><a href="config.html#fs_rpath">_FS_RPATH</a> == 0</tt>)のときは、全てのオブジェクトがルート ディレクトリから辿る絶対パスで指定されます。OS指向なカレント ディレクトリという概念は無く、またドット ディレクトリ(<tt>"."</tt>や<tt>".."</tt>)は使用できません。パス名先頭のセパレータは無視されます。デフォルト ドライブ番号は常に0になります。</p>
+<p>相対パスを有効(<tt>_FS_RPATH &gt;= 1</tt>)にしたときは、先行するセパレータの有無によって検索開始ディレクトリが変わり、セパレータがある場合はルート ディレクトリから、無い場合は<a href="chdir.html"><tt>f_chdir</tt></a>関数で設定されるカレント ディレクトリからになります。またパス名にドット ディレクトリが使用できます。デフォルト ドライブ番号は<a href="chdrive.html"><tt>f_chdrive</tt></a>関数で設定された値となります。</p>
+<table class="lst2">
+<tr><td>パス名の例</td><td>_FS_RPATH == 0</td><td>_FS_RPATH &gt;= 1</td></tr>
+<tr class="lst3"><td>file.txt</td><td>ドライブ0のルート ディレクトリ下のファイル</td><td>カレント ドライブのカレント ディレクトリ下のファイル</td></tr>
+<tr><td>/file.txt</td><td>ドライブ0のルート ディレクトリ下のファイル</td><td>カレント ドライブのルート ディレクトリ下のファイル</td></tr>
+<tr><td></td><td>ドライブ0のルート ディレクトリ</td><td>カレント ドライブのカレント ディレクトリ</td></tr>
+<tr><td>2:</td><td>ドライブ2のルート ディレクトリ</td><td>ドライブ2のカレント ディレクトリ</td></tr>
+<tr><td>2:file1.txt</td><td>ドライブ2のルート ディレクトリ下のファイル</td><td>ドライブ2のカレント ディレクトリ下のファイル</td></tr>
+<tr><td>2:/</td><td>ドライブ2のルート ディレクトリ</td><td>ドライブ2のルート ディレクトリ</td></tr>
+<tr><td>../file.txt</td><td>無効</td><td>親ディレクトリ下のファイル</td></tr>
+<tr><td>.</td><td>無効</td><td>このディレクトリ</td></tr>
+<tr><td>..</td><td>無効</td><td>カレント ディレクトリの親ディレクトリ</td></tr>
+<tr><td>dir1/..</td><td>無効</td><td>カレント ディレクトリ</td></tr>
+<tr><td>/..</td><td>無効</td><td>ルート ディレクトリ(その上は辿れない)</td></tr>
+</table>
+<p>また、<tt><a href="config.html#str_volume_id">_STR_VOLUME_ID</a></tt>オプションを有効にすることでドライブ番号の識別には数字のほか、<tt>"sd:file1.txt"</tt>や<tt>"ram:swapfile.dat"</tt>のように、任意の文字列(もちろんDOS/Windowsライクなドライブ文字も)を使用することも可能になります。</p>
+<p><em>【注意】現リビジョン(R0.12)では、exFATボリューム上においてダブル ドット<tt>".."</tt>はシングル ドット<tt>"."</tt>として機能し、親ディレクトリを辿ることはできません。</em></p>
+</div>
+
+<div class="para doc" id="case">
+<h3>使用可能な文字と大文字小文字の識別</h3>
+<p>FATファイル システムでファイル名に使用可能な文字は、<tt>0～9 A～Z ! # $ % &amp; ' ( ) - @ ^ _ ` { } ~</tt>および拡張文字(<tt>\x80</tt>～<tt>\xFF</tt>)となっています。LFN拡張ではこれらに加え、<tt>+ , ; = [ ]</tt>およびスペースが使用可能になり、スペースとピリオドはファイル名の末尾を除く任意の位置に挿入できます。</p>
+<p>FATファイル システムでは、パス名についてケース インセンシティブです。たとえば、<tt>file.txt, File.Txt, FILE.TXT</tt>の3つの名前は同じ物として扱われます。これは、ASCII文字だけでなく拡張文字についても適用されます。ファイルが作成される際、SFNエントリには全て大文字に変換された名前が記録されます。LFN対応システムでは、LFNエントリには大文字変換されない名前が記録されます。</p>
+<p>古い日本語MS-DOSでは拡張文字(いわゆる全角文字)についてはケース センシティブでした。FatFsモジュールではこれにしたがい、非LFN構成で文字コードにDBCSが選択されたときに限り、拡張文字に対して大文字変換を行わずにSFNエントリに記録および検索されます(日本語MSDOS仕様)。LFN構成では拡張文字についても大文字変換を行います(WindowsNT仕様)。このため、非LFN構成で全角小文字を含む名前でファイルを作成すると、Windowsでそのファイルを開けなくなるなどの互換性問題を起こすので、それらのシステムで相互利用するボリューム上ではDBCS拡張文字の使用は避けるべきです。</p>
+</div>
+
+<div class="para doc" id="uni">
+<h3>Unicode API</h3>
+<p>ファイル関数の入出力のうちファイル名やパス名を指定する引数の型は、<tt>TCHAR</tt>で定義されていますが、これは通常は<tt>char</tt>のエリアスになっています。そして、<tt><a href="config.html#code_page">_CODE_PAGE</a></tt>で指定されるANSI/OEMコード(SBCSまたはDBCS)の文字列として扱われます。ファイル名入出力をUnicodeとする構成(<tt><a href="config.html#lfn_unicode">_LFN_UNICODE</a> == 1</tt>)にしたときは、<tt>TCHAR</tt>はワイド文字(<tt>WCHAR, unsigned short</tt>)に切り替わり、パス名の入出力にUnicodeを使用するようになります。これによりLFN規格に完全対応となり、ファイル名としてANSI/OEMコードにない文字(たとえば ✝☪✡☸☭など)も使用できます。この設定は文字列入出力関数においては、データ型とファイル上のエンコーディングに影響を与えます。リテラル文字列を定義するとき、次に示すように<tt>_T(s)</tt>および<tt>_TEXT(s)</tt>マクロを使ってANSI/OEMとUnicodeを自動切り替えすることができます。</p>
+<pre>
+ f_open(fp, "filename.txt", FA_READ);      <span class="c">/* ANSI/OEM専用コード */</span>
+ f_open(fp, L"filename.txt", FA_READ);     <span class="c">/* Unicode専用コード */</span>
+ f_open(fp, _T("filename.txt"), FA_READ);  <span class="c">/* 両用コード(自動切り替え) */</span>
+</pre>
+</div>
+
+<div class="para doc" id="vol">
+<h3>ボリューム管理</h3>
+<p>デフォルトの構成では、それぞれの論理ドライブは同じ番号の物理ドライブに1:1で結びつけられていて、自動検出機能によりその物理ドライブ上の一つのFATボリュームがマウントされます。FATボリュームの検出は、セクタ0(SFD)、第一区画～第四区画(FDISK)の順に行われます。</p>
+<p><tt><a href="config.html#multi_partition">_MULTI_PARTITION</a></tt>に1を指定すると、それぞれの論理ドライブに対して個別に物理ドライブ番号と区画を指定できるようになります。この構成では、論理ドライブと区画の対応を解決するためのテーブルを次に示すように定義する必要があります。</p>
+<pre>
+例:論理ドライブ0～2を物理ドライブ0(非リムーバブル)の3つの基本区画に割り当て、
+   論理ドライブ3を物理ドライブ1(リムーバブル)に割り当てる場合。
+
+PARTITION VolToPart[] = {
+    {0, 1},     <span class="c">/* "0:" ==> 物理ドライブ 0, 第1区画 */</span>
+    {0, 2},     <span class="c">/* "1:" ==> 物理ドライブ 0, 第2区画 */</span>
+    {0, 3},     <span class="c">/* "2:" ==> 物理ドライブ 0, 第3区画 */</span>
+    {1, 0}      <span class="c">/* "3:" ==> 物理ドライブ 1, 自動検出 */</span>
+};
+</pre>
+<div><img src="../res/f7.png" width="828" height="288" alt="論理ドライブと物理ドライブの関係"></div>
+<p>複数区画指定を使用する場合、次の点に注意しなければなりません。
+<ul>
+<li>複数のマウントされた区画を持つ物理ドライブは、非リムーバブルでなければならず、システム動作中のメディア交換は禁止。</li>
+<li>基本区画のみマウント可能で、拡張区画内の区画には対応しない。</li>
+<li>Windowsは、リムーバブル ドライブでは複数区画をサポートせず、先頭区画のみ認識する。</li>

+<h4>解説</h4>
+<p>ファイルのリード/ライト ポインタ(次に読み出し・書き込みされるバイトのオフセット)を移動します。オフセットの原点はファイル先頭です。書き込みモードでファイル サイズより大きな値を指定すると、そこまでファイル サイズが拡張され、拡張された部分のデータは未定義となります。データを遅延無く高速に書き込みたいときは、予めこの関数で必要なサイズまでファイル サイズを拡張しておくと良いでしょう。ファイルに連続したデータ領域を割り当てる必要があるときは、<tt>f_expand</tt>関数を使用してください。<tt>f_lseek</tt>関数が正常終了したあとは、リード/ライト ポインタが正しく移動したかチェックするべきです。リード/ライト ポインタが指定より小さいときは、次の原因が考えられます。</p>
+<ul>
+<li>非書き込みモードまたは高速シーク モードのため、ファイル サイズでクリップされた。</li>
+<li>ファイル拡張中にディスクが満杯になった。</li>
+</ul>
+<p>高速シーク モードは、ファイルのクラスタ配置情報(CLMT)をメモリ上に保持しておくことにより、FATにアクセスすることなく後方シークやロング シークを高速に行う機能で、シーク動作のほか<tt>f_read/f_wtite</tt>関数の動作にも適用されます。ファイルが高速シーク モードの間は<tt>f_wtite/f_lseek</tt>関数によるファイル サイズの拡張はできません。</p>
+<p>高速シーク モードは、ファイル オブジェクトのメンバ<tt>cltbl</tt>(<tt>f_open</tt>関数でNULLになる)にNULL以外を設定したとき有効になるので、まずCLMTを作成しておく必要があります。これを作成するには、まずCLMT格納バッファ(<tt>DWORD</tt>型配列)を準備し、<tt>cltbl</tt>にそのポインタをセットします。そして、配列の先頭要素にその配列のサイズ(要素数)を入れ、<tt>f_lseek</tt>関数を<tt class="arg">ofs</tt>に<tt>CREATE_LINKMAP</tt>を指定して呼び出します。関数が成功するとCLMTが作成され、以降の<tt>f_read/f_write/f_lseek</tt>関数ではFATへのアクセスは発生しません。CLMTの先頭要素には実際に使用した(または必要となる)要素数が返されます。使用される要素数は、(ファイルの分割数 + 1) * 2 です。たとえば、ファイルが5つのフラグメントに分断されているときは、12要素が使用されます。<tt>FR_NOT_ENOUGH_CORE</tt>で失敗したときは、配列サイズが不足です。</p>

+<h4>説明</h4>
+<p>exFAT以外のボリュームのFATタイプ(FAT12/FAT16/FAT32)は、そのボリューム上の<em>クラスタ数によってのみ決定</em>される決まり[FAT仕様書より]になっていて、それ以外の要因はありません。したがって、どのFATタイプになるかはボリューム サイズとクラスタ サイズに依存します。そのボリュームのサイズにおいて、指定されたFATタイプとクラスタ サイズの組み合わせが成立し得ないときは、関数は<tt>FR_MKFS_ABORTED</tt>で失敗します。</p>
+<p>クラスタとは、データ格納領域の管理の単位のことで、これを単位にファイルにデータ領域が割り当てられます。たとえば、クラスタ サイズが32768のときは、100バイトのファイルも32768バイトのスペースを消費することになります。このように、クラスタ サイズを大きくするほどボリュームの利用効率が悪くなりますが、その一方で読み書きの性能は上がります。クラスタ サイズによる利用効率と性能はトレード オフの関係にあります。GBクラスのストレージでは、極端に多くのファイルを扱わない限り32768バイト以上に(デフォルト指定ではそのようになる)しておくとよいでしょう。</p>
+<p>パーテーション形式には、FDISK形式とSFD形式の二通りあります。FDISK形式は、ハードディスク、マルチメディアカード、SDカード、CFカード、USBメモリなどで標準的に使用されます。FDISK形式では一台の物理ドライブ上に一つまたは複数の区画を作成することができ、区画管理情報はMBR(物理ドライブの先頭セクタ)に記録されます。SFD形式は単に何の分割も行わない形式で、ボリュームは物理ドライブの先頭セクタから開始します。SFD形式は、フロッピー ディスク、マイクロドライブ、光学ディスク、およびその他スーパー フロッピー メディアで標準的に使用されています。システムによっては、FDISK形式またはSFD形式のどちらか一方のみをサポートし他方をサポートしません。</p>
+<p><tt>FM_SFD</tt>が指定されないときはFDISK形式となり、その物理ドライブ全体を占める1個の基本区画(パーテーション)が作成され、その中にFATボリュームが作成されます。<tt>FM_SFD</tt>が指定されたときはSFD形式となり、FATボリュームがその物理ドライブの先頭セクタからベタで作成されます。</p>
+<p>マルチ パーテーション機能(<tt><a href="config.html#multi_partition">_MULTI_PARTITION</a></tt>)により、その論理ドライブが特定の区画(1～4)に結び付けられている場合は、その区画の中にFATボリュームが作成されます。<tt>FM_SFD</tt>の指定は無視され、その物理ドライブはこれに先立ち、<tt>f_fdisk</tt>関数または他のツールで適切に区画設定されている必要があります。</p>

+<h4>解説</h4>
+<p>FatFsモジュールでは、それぞれの論理ドライブに<em>ファイル システム オブジェクト</em>というワーク エリアが必要です。この関数は論理ドライブにファイル システム オブジェクトを登録したり抹消したりします。何らかのファイル関数を使用する前に、この関数でその論理ドライブのファイル システム オブジェクトを与えておかなければなりません。<tt class="arg">fs</tt>にヌル ポインタを指定すると、その論理ドライブのファイル システム オブジェクトの登録は抹消されるだけです。登録抹消されたファイル システム オブジェクトのメモリは解放できます。操作の対象の論理ドライブ上に開かれたままのファイルやディレクトリがあった場合、それらに対して作成された構造体は全て無効になります。この関数の内部処理は次のような順に行われます。</p>
+<ol>
+<li>対象の論理ドライブを<tt class="arg">path</tt>から得る。</li>
+<li>登録されているファイル システム オブジェクトがあるときは、それをクリア(無効化)し、登録を解除する。</li>
+<li><tt class="arg">fs</tt>が有効なポインタのときは、そのファイル システム オブジェクトをクリアし、登録する。</li>
+<li>マウント動作が指定されているときは、それを実行する。</li>
+</ol>
+<p><tt class="arg">opt</tt>に0を指定すると、マウント動作(物理ドライブの初期化、FATボリュームの検索、BPBを解析しファイル システム オブジェクトを初期化)は行われず、関数は物理ドライブの状態に関わらず常に成功します。関数内では下位レイヤへのアクセスは発生せず、指定されたファイル システム オブジェクトをクリア(無効化)し、そのアドレスを内部配列に登録するだけです。単に登録済みのファイル システム オブジェクトをクリアする目的にも使えます。実際のマウント動作は、ボリュームへのアクセス(パス名を渡すもの全て)が行われたときに、次のうちいずれかの条件が真の場合に行われます。</p>
+<ul>
+<li>ファイル システム オブジェクトがクリア(無効)状態(<tt>f_mount</tt>関数の実行による)</li>
+<li>物理ドライブが未初期化状態(システム リセットやメディアの交換による)</li>
+</ul>
+<p><tt class="arg">opt</tt>に1を指定すると、ファイル システムオブジェクトの登録に続きマウント動作が行われます。メディアが無いなどの理由でマウント動作に失敗すると対応するエラーを返しファイル システム オブジェクトはクリア状態のままになりますが、登録自体は有効なので続いてボリュームへのアクセスがあれば再びマウント動作が実行されます。</p>
+<p>下位レイヤの実装上メディア交換の検出がサポートされない(<tt>disk_status</tt>関数に反映されない)ときは、アプリケーションはメディア交換の後この関数でファイル システム オブジェクトを明示的にクリアし、マウント動作が正常に行えるようにする必要があります。</p>

+</ul>
+<p>exFATボリュームのディレクトリを読み出すとき、構成によっては問題が発生します。exFATでは短いファイル名がサポートされません。つまり、上記の条件のとき代わりに返すファイル名が無いということです。このような場合は<tt>fname[]</tt>に"?"が返され、そのオブジェクトにアクセスできないことを示します。この問題を避けるには、FatFsの構成を<tt>_LFN_UNICODE = 1</tt>および<tt>_MAX_LFN = 255</tt>として長いファイル名に完全対応とする必要があります。</p>

+R0.12b (September 4, 2016)
+  Improved f_rename() to be able to rename objects with the same name but case.
+  Fixed an error in the case conversion teble of code page 866. (ff.c)
+  Fixed writing data is truncated at the file offset 4GiB on the exFAT volume. (appeared at R0.12)
+  Fixed creating a file in the root directory of exFAT volume can fail. (appeared at R0.12)
+  Fixed f_mkfs() creating exFAT volume with too small cluster size can collapse unallocated memory. (appeared at R0.12)
+  Fixed wrong object name can be returned when read directory at Unicode cfg. (appeared at R0.12)
+  Fixed large file allocation/removing on the exFAT volume collapses allocation bitmap. (appeared at R0.12)
+  Fixed some internal errors in f_expand() and f_lseek(). (appeared at R0.12)
+
+R0.12a (July 10, 2016)
+  Added support for creating exFAT volume with some changes of f_mkfs().
+  Added a file open method FA_OPEN_APPEND. An f_lseek() following f_open() is no longer needed.
+  f_forward() is available regardless of _FS_TINY.

+ * message has been received and is ready for processing", bit 1 might mean "The
+ * application has queued a message that is ready for sending onto the CAN
+ * network", and bit 2 might mean "It is time to send a SYNC message onto the
+ * CAN network" etc.  A task can then test the bit values to see which events
+ * are active, and optionally enter the Blocked state to wait for a specified
+ * bit or a group of specified bits to be active.  To continue the CAN bus
+ * example, a CAN controlling task can enter the Blocked state (and therefore
+ * not consume any processing time) until either bit 0, bit 1 or bit 2 are
+ * active, at which time the bit that was actually active would inform the task
+ * which action it had to take (process a received message, send a message, or
+ * send a SYNC).
+ *
+ * The event groups implementation contains intelligence to avoid race
+ * conditions that would otherwise occur were an application to use a simple
+ * variable for the same purpose.  This is particularly important with respect
+ * to when a bit within an event group is to be cleared, and when bits have to

+ * Message buffers build functionality on top of FreeRTOS stream buffers.
+ * Whereas stream buffers are used to send a continuous stream of data from one
+ * task or interrupt to another, message buffers are used to send variable
+ * length discrete messages from one task or interrupt to another.  Their
+ * implementation is light weight, making them particularly suited for interrupt
+ * to task and core to core communication scenarios.
+ *
+ * ***NOTE***:  Uniquely among FreeRTOS objects, the stream buffer
+ * implementation (so also the message buffer implementation, as message buffers
+ * are built on top of stream buffers) assumes there is only one task or
+ * interrupt that will write to the buffer (the writer), and only one task or
+ * interrupt that will read from the buffer (the reader).  It is safe for the
+ * writer and reader to be different tasks or interrupts, but, unlike other
+ * FreeRTOS objects, it is not safe to have multiple different writers or
+ * multiple different readers.  If there are to be multiple different writers
+ * then the application writer must place each call to a writing API function
+ * (such as xMessageBufferSend()) inside a critical section and set the send
+ * block time to 0.  Likewise, if there are to be multiple different readers
+ * then the application writer must place each call to a reading API function
+ * (such as xMessageBufferRead()) inside a critical section and set the receive
+ * timeout to 0.
+ *
+ * Message buffers hold variable length messages.  To enable that, when a
+ * message is written to the message buffer an additional sizeof( size_t ) bytes
+ * are also written to store the message's length (that happens internally, with
+ * the API function).  sizeof( size_t ) is typically 4 bytes on a 32-bit
+ * architecture, so writing a 10 byte message to a message buffer on a 32-bit
+ * architecture will actually reduce the available space in the message buffer
+ * by 14 bytes (10 byte are used by the message, and 4 bytes to hold the length
+ * of the message).

+ *
+ * For advanced users only.
+ *
+ * The sbRECEIVE_COMPLETED() macro is called from within the FreeRTOS APIs when
+ * data is read out of a message buffer or stream buffer.  If there was a task
+ * that was blocked on the message or stream buffer waiting for data to arrive
+ * then the sbRECEIVE_COMPLETED() macro sends a notification to the task to
+ * remove it from the Blocked state.  xMessageBufferReceiveCompletedFromISR()
+ * does the same thing.  It is provided to enable application writers to
+ * implement their own version of sbRECEIVE_COMPLETED(), and MUST NOT BE USED AT
+ * ANY OTHER TIME.
+ *
+ * See the example implemented in FreeRTOS/Demo/Minimal/MessageBufferAMP.c for
+ * additional information.
+ *
+ * @param xStreamBuffer The handle of the stream buffer from which data was
+ * read.
+ *
+ * @param pxHigherPriorityTaskWoken *pxHigherPriorityTaskWoken should be
+ * initialised to pdFALSE before it is passed into
+ * xMessageBufferReceiveCompletedFromISR().  If calling
+ * xMessageBufferReceiveCompletedFromISR() removes a task from the Blocked state,
+ * and the task has a priority above the priority of the currently running task,
+ * then *pxHigherPriorityTaskWoken will get set to pdTRUE indicating that a
+ * context switch should be performed before exiting the ISR.
+ *
+ * @return If a task was removed from the Blocked state then pdTRUE is returned.
+ * Otherwise pdFALSE is returned.

+ * interrupt that will read from the buffer (the reader).  It is safe for the
+ * writer and reader to be different tasks or interrupts, but, unlike other
+ * FreeRTOS objects, it is not safe to have multiple different writers or
+ * multiple different readers.  If there are to be multiple different writers
+ * then the application writer must place each call to a writing API function
+ * (such as xStreamBufferSend()) inside a critical section and set the send
+ * block time to 0.  Likewise, if there are to be multiple different readers
+ * then the application writer must place each call to a reading API function
+ * (such as xStreamBufferRead()) inside a critical section and set the receive
+ * block time to 0.

+ * empty.  xStreamBufferReceive() will return immediately if xTicksToWait is
+ * zero.  The block time is specified in tick periods, so the absolute time it

+ * Internally, within the FreeRTOS implementation, tasks use two blocks of

+ *
+ * See xTaskCreateStatic() for a version that does not use any dynamic memory

+ *
+ * xTaskCreate() can only be used to create a task that has unrestricted

+ * variables the stack can hold - not the number of bytes.  For example, if

+ * will be allocated for stack storage.
+ *
+ * @param pvParameters Pointer that will be used as the parameter for the task

+ * next executes.  See vTaskDelayUntil() for an alternative API function designed

+ * Creates a new software timer instance, and returns a handle by which the

+ *
+ * Internally, within the FreeRTOS implementation, software timers use a block
+ * of memory, in which the timer data structure is stored.  If a software timer
+ * is created using xTimerCreate() then the required memory is automatically
+ * dynamically allocated inside the xTimerCreate() function.  (see
+ * http://www.freertos.org/a00111.html).  If a software timer is created using
+ * xTimerCreateStatic() then the application writer must provide the memory that
+ * will get used by the software timer.  xTimerCreateStatic() therefore allows a
+ * software timer to be created without using any dynamic memory allocation.
+ *
+ * Timers are created in the dormant state.  The xTimerStart(), xTimerReset(),
+ * xTimerStartFromISR(), xTimerResetFromISR(), xTimerChangePeriod() and
+ * xTimerChangePeriodFromISR() API functions can all be used to transition a
+ * timer into the active state.
+ *
+ * @param pcTimerName A text name that is assigned to the timer.  This is done
+ * purely to assist debugging.  The kernel itself only ever references a timer
+ * by its handle, and never by its name.
+ *
+ * @param xTimerPeriodInTicks The timer period.  The time is defined in tick
+ * periods so the constant portTICK_PERIOD_MS can be used to convert a time that
+ * has been specified in milliseconds.  For example, if the timer must expire
+ * after 100 ticks, then xTimerPeriodInTicks should be set to 100.
+ * Alternatively, if the timer must expire after 500ms, then xPeriod can be set
+ * to ( 500 / portTICK_PERIOD_MS ) provided configTICK_RATE_HZ is less than or
+ * equal to 1000.
+ *
+ * @param uxAutoReload If uxAutoReload is set to pdTRUE then the timer will
+ * expire repeatedly with a frequency set by the xTimerPeriodInTicks parameter.
+ * If uxAutoReload is set to pdFALSE then the timer will be a one-shot timer and
+ * enter the dormant state after it expires.
+ *
+ * @param pvTimerID An identifier that is assigned to the timer being created.
+ * Typically this would be used in the timer callback function to identify which
+ * timer expired when the same callback function is assigned to more than one
+ * timer.
+ *
+ * @param pxCallbackFunction The function to call when the timer expires.
+ * Callback functions must have the prototype defined by TimerCallbackFunction_t,
+ * which is	"void vCallbackFunction( TimerHandle_t xTimer );".
+ *
+ * @return If the timer is successfully created then a handle to the newly
+ * created timer is returned.  If the timer cannot be created (because either
+ * there is insufficient FreeRTOS heap remaining to allocate the timer
+ * structures, or the timer period was set to 0) then NULL is returned.

+ * Creates a new software timer instance, and returns a handle by which the
+ * created software timer can be referenced.
+ *
+ * Internally, within the FreeRTOS implementation, software timers use a block
+ * of memory, in which the timer data structure is stored.  If a software timer
+ * is created using xTimerCreate() then the required memory is automatically
+ * dynamically allocated inside the xTimerCreate() function.  (see
+ * http://www.freertos.org/a00111.html).  If a software timer is created using
+ * xTimerCreateStatic() then the application writer must provide the memory that
+ * will get used by the software timer.  xTimerCreateStatic() therefore allows a
+ * software timer to be created without using any dynamic memory allocation.
+ *
+ * Timers are created in the dormant state.  The xTimerStart(), xTimerReset(),
+ * xTimerStartFromISR(), xTimerResetFromISR(), xTimerChangePeriod() and
+ * xTimerChangePeriodFromISR() API functions can all be used to transition a
+ * timer into the active state.
+ *
+ * @param pcTimerName A text name that is assigned to the timer.  This is done
+ * purely to assist debugging.  The kernel itself only ever references a timer
+ * by its handle, and never by its name.
+ *
+ * @param xTimerPeriodInTicks The timer period.  The time is defined in tick
+ * periods so the constant portTICK_PERIOD_MS can be used to convert a time that
+ * has been specified in milliseconds.  For example, if the timer must expire
+ * after 100 ticks, then xTimerPeriodInTicks should be set to 100.
+ * Alternatively, if the timer must expire after 500ms, then xPeriod can be set
+ * to ( 500 / portTICK_PERIOD_MS ) provided configTICK_RATE_HZ is less than or
+ * equal to 1000.
+ *
+ * @param uxAutoReload If uxAutoReload is set to pdTRUE then the timer will
+ * expire repeatedly with a frequency set by the xTimerPeriodInTicks parameter.
+ * If uxAutoReload is set to pdFALSE then the timer will be a one-shot timer and
+ * enter the dormant state after it expires.
+ *
+ * @param pvTimerID An identifier that is assigned to the timer being created.
+ * Typically this would be used in the timer callback function to identify which
+ * timer expired when the same callback function is assigned to more than one
+ * timer.
+ *
+ * @param pxCallbackFunction The function to call when the timer expires.
+ * Callback functions must have the prototype defined by TimerCallbackFunction_t,
+ * which is "void vCallbackFunction( TimerHandle_t xTimer );".
+ *
+ * @param pxTimerBuffer Must point to a variable of type StaticTimer_t, which
+ * will be then be used to hold the software timer's data structures, removing
+ * the need for the memory to be allocated dynamically.
+ *
+ * @return If the timer is created then a handle to the created timer is
+ * returned.  If pxTimerBuffer was NULL then NULL is returned.
+ *
+ * Example usage:
+ * @verbatim
+ *
+ * // The buffer used to hold the software timer's data structure.
+ * static StaticTimer_t xTimerBuffer;
+ *
+ * // A variable that will be incremented by the software timer's callback

+ * Ideally an interrupt service routine (ISR) is kept as short as possible, but

+ * xTimerPendFunctionCallFromISR() can be used to defer processing of a function
+ * to the RTOS daemon task.
+ *
+ * A mechanism is provided that allows the interrupt to return directly to the

+ *
+ * @param xFunctionToPend The function to execute from the timer service/

+ *
+ * @param pvParameter1 The value of the callback function's first parameter.
+ * The parameter has a void * type to allow it to be used to pass any type.
+ * For example, unsigned longs can be cast to a void *, or the void * can be
+ * used to point to a structure.
+ *
+ * @param ulParameter2 The value of the callback function's second parameter.
+ *
+ * @param pxHigherPriorityTaskWoken As mentioned above, calling this function
+ * will result in a message being sent to the timer daemon task.  If the
+ * priority of the timer daemon task (which is set using
+ * configTIMER_TASK_PRIORITY in FreeRTOSConfig.h) is higher than the priority of
+ * the currently running task (the task the interrupt interrupted) then
+ * *pxHigherPriorityTaskWoken will be set to pdTRUE within
+ * xTimerPendFunctionCallFromISR(), indicating that a context switch should be
+ * requested before the interrupt exits.  For that reason
+ * *pxHigherPriorityTaskWoken must be initialised to pdFALSE.  See the
+ * example code below.
+ *
+ * @return pdPASS is returned if the message was successfully sent to the
+ * timer daemon task, otherwise pdFALSE is returned.

+			2) Incorrect interrupt priority assignment, especially on Cortex-M
+			   parts where numerically high priority values denote low actual
+			   interrupt priorities, which can seem counter intuitive.  See
+			   http://www.freertos.org/RTOS-Cortex-M3-M4.html and the definition
+			   of configMAX_SYSCALL_INTERRUPT_PRIORITY on
+			   http://www.freertos.org/a00110.html
+			3) Calling an API function from within a critical section or when
+			   the scheduler is suspended, or calling an API function that does
+			   not end in "FromISR" from an interrupt.
+			4) Using a queue or semaphore before it has been initialised or

+			   before vTaskStartScheduler() has been called?).

+Each real time kernel port consists of three files that contain the core kernel
+components and are common to every port, and one or more files that are
+specific to a particular microcontroller and/or compiler.
+
+
++ The FreeRTOS/Source/Portable/MemMang directory contains the five sample
+memory allocators as described on the http://www.FreeRTOS.org WEB site.
+
++ The other directories each contain files specific to a particular
+microcontroller or compiler, where the directory name denotes the compiler
+specific files the directory contains.
+
+
+
+For example, if you are interested in the [compiler] port for the [architecture]
+microcontroller, then the port specific files are contained in
+FreeRTOS/Source/Portable/[compiler]/[architecture] directory.  If this is the
+only port you are interested in then all the other directories can be
+ignored.

+ * Platform abstraction layer API to set the bitrate/speed(KHz) of I2C master.
+ * <br>
+ *
+ *<b>API Details:</b>
+ * - Sets the bitrate of I2C master if the I2C bus is free, else it returns busy status #PAL_STATUS_I2C_BUSY<br>
+ * - The bus is released after the setting the bitrate.<br>
+ * - This API must take care of setting the bitrate to I2C master's maximum supported value. 
+ * - Eg. In XMC4500, the maximum supported bitrate is 400 KHz. If the supplied bitrate is greater than 400KHz, the API will 
+ *   set the I2C master's bitrate to 400KHz.
+ * - Use the #PAL_I2C_MASTER_MAX_BITRATE macro to specify the maximum supported bitrate value for the target platform.
+ * - If upper_layer_event_handler is initialized, the upper layer handler is invoked with the respective event 
+ *   status listed below.
+ *   - #PAL_I2C_EVENT_BUSY when I2C bus in busy state
+ *   - #PAL_I2C_EVENT_ERROR when API fails to set the bit rate 
+ *   - #PAL_I2C_EVENT_SUCCESS when operation is successful
+ *<br>
+ *
+ *<b>User Input:</b><br>
+ * - The input #pal_i2c_t  p_i2c_context must not be NULL.<br>
+ *
+ * \param[in] p_i2c_context  Pointer to the pal i2c context
+ * \param[in] bitrate        Bitrate to be used by i2c master in KHz

+
+  2016-12-15: David van Moolenbroek
+  * opt.h, tcp: added LWIP_HOOK_TCP_ISN() to implement less predictable initial

+(STABLE-2.0.0)
+
+  ++ New features:
+
+  2016-07-27: Simon Goldschmidt
+  * opt.h, timeouts.h/.c: added LWIP_TIMERS_CUSTOM to override the default
+    implementation of timeouts
+
+  2016-07-xx: Dirk Ziegelmeier
+  * Large overhaul of doxygen documentation
+
+  2016-04-05: Simon Goldschmidt
+  * timers.h/.c: prepare for overriding current timeout implementation: all
+    stack-internal caclic timers are avaliable in the lwip_cyclic_timers array
+
+  2016-03-23: Simon Goldschmidt
+  * tcp: call accept-callback with ERR_MEM when allocating a pcb fails on
+    passive open to inform the application about this error
+    ATTENTION: applications have to handle NULL pcb in accept callback!
+
+  2016-02-22: Ivan Delamer
+  * Initial 6LoWPAN support
+
+  2016-02-XX to 2016-03-XX: Dirk Ziegelmeier
+  * Cleanup TCPIP thread sync methods in a way that it is possibe to use them
+    in arbitrary code that needs things to be done in TCPIP thread. Used to
+    decouple netconn, netif, ppp and 6LoWPAN from LWIP core.
+
+  2016-02-XX: Dirk Ziegelmeier
+  * Implement dual-stack support in RAW, UDP and TCP. Add new IP address
+    type IPADDR_ANY_TYPE for this. Netconn/Socket API: Dual-stack is
+    automatically supported when an IPv6 netconn/socket is created.
+
+  2015-12-26: Martin Hentschel and Dirk Ziegelmeier
+  * Rewrite SNMP agent. SNMPv2c + MIB compiler.
+
+  2015-11-12: Dirk Ziegelmeier
+  * Decouple SNMP stack from lwIP core and move stack to apps/ directory.
+    Breaking change: Users have to call snmp_init() now!
+
+  2015-11-12: Dirk Ziegelmeier
+  * Implement possibility to declare private memory pools. This is useful to
+    decouple some apps from the core (SNMP stack) or make contrib app usage
+    simpler (httpserver_raw)
+
+  2015-10-09: Simon Goldschmidt
+  * started to move "private" header files containing implementation details to
+    "lwip/priv/" include directory to seperate the API from the implementation.
+
+  2015-10-07: Simon Goldschmidt
+  * added sntp client as first "supported" application layer protocol implementation
+    added 'apps' folder
+
+  2015-09-30: Dirk Ziegelmeier
+  * snmp_structs.h, mib_structs.c, mib2.c: snmp: fixed ugly inheritance
+    implementation by aggregating the "base class" (struct mib_node) in all
+    derived node classes to get more type-safe code
+
+  2015-09-23: Simon Goldschmidt
+  * netif.h/.c, nd6.c: task #13729: Convert netif addresses (IPv4 & IPv6) to
+    ip_addr_t (so they can be used without conversion/temporary storage)
+
+  2015-09-08: Dirk Ziegelmeier
+  * snmp: Separate mib2 counter/table callbacks from snmp agent. This both cleans
+    up the code and should allow integration of a 3rd party agent/mib2. Simple
+    counters are kept in MIB2_STATS, tree/table change function prototypes moved to
+    snmp_mib2.h.
+
+  2015-09-03: Simon Goldschmidt
+  * opt.h, dns.h/.c: DNS/IPv6: added support for AAAA records
+
+  2015-09-01: Simon Goldschmidt
+  * task #12178: hardware checksum capabilities can be configured per netif
+   (use NETIF_SET_CHECKSUM_CTRL() in your netif's init function)
+
+  2015-08-30: Simon Goldschmidt
+  * PBUF_REF with "custom" pbufs is now supported for RX pbufs (see pcapif in
+    contrib for an example, LWIP_SUPPORT_CUSTOM_PBUF is required)
+
+  2015-08-30: Simon Goldschmidt
+  * support IPv4 source based routing: define LWIP_HOOK_IP4_ROUTE_SRC to point
+    to a routing function
+
+  2015-08-05: Simon Goldschmidt
+  * many files: allow multicast socket options IP_MULTICAST_TTL, IP_MULTICAST_IF
+    and IP_MULTICAST_LOOP to be used without IGMP
+
+  2015-04-24: Simon Goldschmidt
+  * dhcp.h/c, autoip.h/.c: added functions dhcp/autoip_supplied_address() to
+    check for the source of address assignment (replacement for NETIF_FLAG_DHCP)
+
+  2015-04-10: Simon Goldschmidt
+  * many files: task #13480: added LWIP_IPV4 define - IPv4 can be disabled,
+    leaving an IPv6-only stack
+
+  2015-04-09: Simon Goldschmidt
+  * nearly all files: task #12722 (improve IPv4/v6 address handling): renamed
+    ip_addr_t to ip4_addr_t, renamed ipX_addr_t to ip_addr_t and added IP
+    version; ip_addr_t is used for all generic IP addresses for the API,
+    ip(4/6)_addr_t are only used internally or when initializing netifs or when
+    calling version-related functions
+
+  2015-03-24: Simon Goldschmidt
+  * opt.h, ip4_addr.h, ip4.c, ip6.c: loopif is not required for loopback traffic
+    any more but passed through any netif (ENABLE_LOOPBACK has to be enabled)
+
+  2015-03-23: Simon Goldschmidt
+  * opt.h, etharp.c: with ETHARP_TABLE_MATCH_NETIF== 1, duplicate (Auto)-IP
+    addresses on multiple netifs should now be working correctly (if correctly
+    addressed by routing, that is)
+
+  2015-03-23: Simon Goldschmidt
+  * etharp.c: Stable etharp entries that are about to expire are now refreshed
+    using unicast to prevent unnecessary broadcast. Only if no answer is received
+    after 15 seconds, broadcast is used.
+
+  2015-03-06: Philip Gladstone
+  * netif.h/.c: patch #8359 (Provide utility function to add an IPv6 address to
+    an interface)
+
+  2015-03-05: Simon Goldschmidt
+  * netif.c, ip4.c, dhcp.c, autoip.c: fixed bug #37068 (netif up/down handling
+    is unclear): correclty separated administrative status of a netif (up/down)
+    from 'valid address' status
+    ATTENTION: netif_set_up() now always has to be called, even when dhcp/autoip
+    is used!
+
+  2015-02-26: patch by TabascoEye
+  * netif.c, udp.h/.c: fixed bug #40753 (re-bind UDP pcbs on change of IP address)
+
+  2015-02-22: chrysn, Simon Goldschmidt
+  * *.*: Changed nearly all functions taking 'ip(X)_addr_t' pointer to take
+    const pointers (changed user callbacks: raw_recv_fn, udp_recv_fn; changed
+    port callbacks: netif_output_fn, netif_igmp_mac_filter_fn)
+
+  2015-02-19: Ivan Delamer
+  * netif.h, dhcp.c: Removed unused netif flag for DHCP. The preferred way to evaluate
+    if DHCP is active is through netif->dhcp field.
+
+  2015-02-19: Ivan Delamer
+  * netif.h, slipif.c, ppp.c: Removed unused netif flag for point to point connections
+
+  2015-02-18: Simon Goldschmidt
+  * api_lib.c: fixed bug #37958 "netconn API doesn't handle correctly
+    connections half-closed by peer"
+
+  2015-02-18: Simon Goldschmidt
+  * tcp.c: tcp_alloc() prefers killing CLOSING/LAST_ACK over active connections
+    (see bug #39565)
+
+  2015-02-16: Claudius Zingerli, Sergio Caprile
+  * opt.h, dhcp.h/.c: patch #8361 "Add support for NTP option in DHCP"
+
+  2015-02-14: Simon Goldschmidt
+  * opt.h, snmp*: added support for write-access community and dedicated
+    community for sending traps
+
+  2015-02-13: Simon Goldschmidt
+  * opt.h, memp.c: added hook LWIP_HOOK_MEMP_AVAILABLE() to get informed when
+    a memp pool was empty and an item is now available
+
+  2015-02-13: Simon Goldschmidt
+  * opt.h, pbuf.h/.c, etharp.c: Added the option PBUF_LINK_ENCAPSULATION_HLEN to
+    allocate additional header space for TX on netifs requiring additional headers
+
+  2015-02-12: chrysn
+  * timers.h/.c: introduce sys_timeouts_sleeptime (returns the time left before
+    the next timeout is due, for NO_SYS==1)

+    with defined offset"
+
+  2015-02-11: Frederick Baksik
+  * opt.h, def.h, others: patch #8423 "arch/perf.h" should be made an optional item
+
+  2015-02-11: Simon Goldschmidt
+  * api_msg.c, opt.h: started to implement fullduplex sockets/netconns
+    (note that this is highly unstable yet!)
+
+  2015-01-17: Simon Goldschmidt
+  * api: allow enabling socket API without (public) netconn API - netconn API is
+    still used by sockets, but keeping it private (static) should allow better
+    compiler optimizations
+
+  2015-01-16: Simon Goldschmidt
+  * tcp_in.c: fixed bug #20506 "Initial congestion window is very small" again
+    by implementing the calculation formula from RFC3390
+
+  2014-12-10: Simon Goldschmidt
+  * api: added option LWIP_NETCONN_SEM_PER_THREAD to use a semaphore per thread
+    instead of using one per netconn and per select call
+
+  2014-12-08: Simon Goldschmidt
+  * ip6.h: fixed bug #43778: IPv6 header version not set on 16-bit platform
+    (macro IP6H_VTCFL_SET())
+
+  2014-12-08: Simon Goldschmidt
+  * icmp.c, ip4.c, pbuf.c, udp.c, pbuf.h: task #11472 Support PBUF_REF for RX
+    (IPv6 and IPv4/v6 reassembly might not work yet)
+
+  2014-11-06: Simon Goldschmidt
+  * sockets.c/.h, init.c: lwip_socket_init() is not needed any more
+    -> compatibility define
+
+  2014-09-16: Simon Goldschmidt
+  * dns.c, opt.h: reduced ram usage by parsing DNS responses in place
+
+  2014-09-16: Simon Goldschmidt
+  * pbuf.h/.c: added pbuf_take_at() and pbuf_put_at()
+
+  2014-09-15: Simon Goldschmidt
+  * dns.c: added source port randomization to make the DNS client more robust
+    (see bug #43144)
+
+  2013-09-02: Simon Goldschmidt
+  * arch.h and many other files: added optional macros PACK_STRUCT_FLD_8() and
+    PACK_STRUCT_FLD_S() to prevent gcc 4 from warning about struct members that
+    do not need packing
+
+  2013-08-19: Simon Goldschmidt
+  * netif.h: bug #42998: made NETIF_MAX_HWADDR_LEN overridable for some special
+    networks
+
+  2013-03-17: Simon Goldschmidt (patch by Ghobad Emadi)

+    with VLAN headers via hook function LWIP_HOOK_VLAN_SET and to check them
+    via hook function LWIP_HOOK_VLAN_CHECK
+
+  2014-02-20: Simon Goldschmidt (based on patch by Artem Pisarenko)
+  * patch #7885: modification of api modules to support FreeRTOS-MPU
+    (don't pass stack-pointers to other threads)
+
+  2014-02-05: Simon Goldschmidt (patch by "xtian" and "alex_ab")
+  * patch #6537/#7858: TCP window scaling support
+
+  2014-01-17: Jiri Engelthaler

+    IPv6 ICMP's
+
+  2012-08-22: Sylvain Rochet
+  * New PPP stack for lwIP, developed in ppp-new branch.
+    Based from pppd 2.4.5, released 2009-11-17, with huge changes to match
+    code size and memory requirements for embedded devices, including:
+    - Gluing together the previous low-level PPP code in lwIP to pppd 2.4.5, which
+      is more or less what pppd sys-* files are, so that we get something working
+      using the unix port.
+    - Merged some patchs from lwIP Git repository which add interesting features
+      or fix bugs.
+    - Merged some patchs from Debian pppd package which add interesting features
+      or fix bugs.
+    - Ported PPP timeout handling to the lwIP timers system
+    - Disabled all the PPP code using filesystem access, replaced in necessary cases
+      to configuration variables.
+    - Disabled all the PPP code forking processes.
+    - Removed IPX support, lwIP does not support IPX.
+    - Ported and improved random module from the previous PPP port.
+    - Removed samba TDB (file-driven database) usage, because it needs a filesystem.
+    - MS-CHAP required a DES implementation, we added the latest PolarSSL DES
+      implementation which is under a BSD-ish license.
+    - Also switched to PolarSSL MD4,MD5,SHA1 implementations, which are meant to be
+      used in embedded devices with reduced memory footprint.
+    - Removed PPP configuration file parsing support. 
+    - Added macro definition EAP_SUPPORT to make EAP support optional.
+    - Added macro definition CHAP_SUPPORT to make CHAP support optional.
+    - Added macro definition MSCHAP_SUPPORT to make MSCHAP support optional.
+    - Added macro definition PAP_SUPPORT to make PAP support optional.
+    - Cleared all Linux syscall calls.
+    - Disabled demand support using a macro, so that it can be ported later.
+    - Disabled ECP support using a macro, so that it can be ported later.
+    - Disabled CCP support using a macro, so that it can be ported later.
+    - Disabled CBCP support using a macro, so that it can be ported later.
+    - Disabled LQR support using a macro, so that it can be ported later.
+    - Print packet debug feature optional, through PRINTPKT_SUPPORT
+    - Removed POSIX signal usage.
+    - Fully ported PPPoS code from the previous port.
+    - Fully ported PPPoE code from the previous port.
+    - Fully ported VJ compression protocol code from the previous port.
+    - Removed all malloc()/free() use from PPP, replaced by stack usage or PBUF.
+    - Disabled PPP server support using a macro, so that it can be ported later.
+    - Switched all PPP debug to lwIP debug system.
+    - Created PPP Control Block (PPP PCB), removed PPP unit integer everywhere,
+      removed all global variables everywhere, did everything necessary for
+      the PPP stack to support more than one PPP session (pppd only support
+      one session per process).
+    - Removed the statically allocated output buffer, now using PBUF.
+    - Improved structure size of all PPP modules, deep analyze of code to reduce
+      variables size to the bare minimum. Switched all boolean type (char type in
+      most architecture) to compiler generated bitfields.
+    - Added PPP IPv6 support, glued lwIP IPv6 support to PPP.
+    - Now using a persistent netif interface which can then be used in lwIP
+      functions requiring a netif.
+    - Now initializing PPP in lwip_init() function.
+    - Reworked completely the PPP state machine, so that we don't end up in
+      anymore in inconsistent state, especially with PPPoE.
+    - Improved the way we handle PPP reconnection after disconnect, cleaning
+      everything required so that we start the PPP connection again from a
+      clean state.
+    - Added PPP holdoff support, allow the lwIP user to wait a little bit before
+      reconnecting, prevents connection flood, especially when using PPPoL2TP.
+    - Added PPPoL2TP LAC support (a.k.a. UDP tunnels), adding a VPN client
+      feature to lwIP, L2TP being a widely used tunnel protocol.
+    - Switched all used PPP types to lwIP types (u8t, u16t, u32t, ...)
+    - Added PPP API "sequential" thread-safe API, based from NETIFAPI.
+
+  2011-07-21: Simon Goldschmidt
+  * sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes
+    ioctl/FIONREAD return the size of the next pending datagram.
+
+  2011-05-25: Simon Goldschmidt
+  * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c,
+    combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4
+    and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP
+    code so that the code is more readable.
+
+  2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt)
+  * nearly the whole stack: Finally, we got decent IPv6 support, big thanks to
+    Ivan! (this is work in progress: we're just post release anyway :-)
+
+
+  ++ Bugfixes:
+
+  2016-08-23: Simon Goldschmidt
+  * etharp: removed ETHARP_TRUST_IP_MAC since it is insecure and we don't need
+    it any more after implementing unicast ARP renewal towards arp entry timeout
+
+  2016-07-20: Simon Goldschmidt
+  * memp.h/.c: fixed bug #48442 (memp stats don't work for MEMP_MEM_MALLOC)
+
+  2016-07-21: Simon Goldschmidt (patch by Ambroz Bizjak)
+  * tcp_in.c, tcp_out.c: fixed bug #48543 (TCP sent callback may prematurely

+    SYN/FIN in snd_buf counter
+
+  2016-07-19: Simon Goldschmidt
+  * etharp.c: fixed bug #48477 (ARP input packet might update static entry)

+  * tcp_in.c: fixed bug #48476 (TCP sent callback called wrongly due to picking
+    up old pcb->acked

+
+  2016-04-05: Simon Goldschmidt
+  * netconn/socket API: fixed bug# 43739 (Accept not reporting errors about
+    aborted connections): netconn_accept() returns ERR_ABRT (sockets: ECONNABORTED)
+    for aborted connections, ERR_CLSD (sockets: EINVAL) if the listening netconn
+    is closed, which better seems to follow the standard.
+
+  2016-03-23: Florent Matignon
+  * dhcp.c: fixed bug #38203: DHCP options are not recorded in all DHCP ack messages
+
+  2016-03-22: Simon Goldschmidt
+  * tcp: changed accept handling to be done internally: the application does not
+    have to call tcp_accepted() any more. Instead, when delaying accept (e.g. sockets
+    do), call tcp_backlog_delayed()/tcp_backlog_accepted() (fixes bug #46696)
+
+  2016-03-22: Simon Goldschmidt

+  * api_msg.c: fixed bug #47448 (netconn/socket leak if RST is received during close)
+
+  2016-03-17: Joel Cunningham
+  * api_msg.c: don't fail closing a socket/netconn when failing to allocate the
+    FIN segment; blocking the calling thread for a while is better than risking
+    leaking a netconn/socket (see bug #46701)
+
+  2016-03-16: Joel Cunningham
+  * tcp_out.c: reset rto timer on fast retransmission

+    of all address parts
+
+  2015-08-28: Simon Goldschmidt
+  * tcp.c, tcp_in.c: fixed bug #44023: TCP ssthresh value is unclear: ssthresh
+    is set to the full send window for active open, too, and is updated once
+    after SYN to ensure the correct send window is used
+
+  2015-08-28: Simon Goldschmidt
+  * tcp: fixed bug #45559: Window scaling casts u32_t to u16_t without checks
+
+  2015-08-26: Simon Goldschmidt
+  * ip6_frag.h/.c: fixed bug bug #41009: IPv6 reassembly broken on 64-bit platforms:
+    define IPV6_FRAG_COPYHEADER==1 on these platforms to copy the IPv6 header
+    instead of referencing it, which gives more room for struct ip6_reass_helper
+
+  2015-08-25: Simon Goldschmidt

+
+  2015-02-18: Simon Goldschmidt

+    connected
+
+  2015-02-17: Simon Goldschmidt
+  * tcp_impl.h, tcp_out.c, tcp.c, api_msg.c: fixed bug #37614 "Errors from

+    can call tcp_txnow() (from tcpip_thread!) to try to send again if TX buffers
+    are available again.

+    netif is available through ip_current_input_netif() if required.

+    for LWIP_TCPIP_CORE_LOCKING==1
+
+  2015-02-10: Simon Goldschmidt
+  * netconn/socket api: fixed bug #44225 "closing TCP socket should time out

+    no-copy data with odd length
+
+  2014-12-10: Simon Goldschmidt
+  * sockets.c, tcp.c, others: fixed bug #43797 set/getsockopt: SO_SNDTIMEO/SO_RCVTIMEO
+    take int as option but should take timeval (LWIP_SO_SNDRCVTIMEO_STANDARD==0 can
+    be used to revert to the old 'winsock' style behaviour)
+    Fixed implementation of SO_ACCEPTCONN to just look at the pcb state

+ 2011-09-11: Simon Goldschmidt
+  * opt.h, tcp_impl.h, tcp.c, udp.h/.c: Added a config option to randomize

+
+  2011-07-21: Simon Goldschmidt (patch by hanhui)
+  * ip4.c, etharp.c, pbuf.h: bug #33634 ip_forward() have a faulty behaviour:

+    Also added code to allow ip_forward() to forward non-broadcast packets to
+    the input netif (set IP_FORWARD_ALLOW_TX_ON_RX_NETIF==1).
+
+  2011-06-26: Simon Goldschmidt (patch by Cameron Gutman)

+(STABLE-1.4.0)
+
+  ++ New features:
+
+  2011-03-27: Simon Goldschmidt
+  * tcp_impl.h, tcp_in.c, tcp_out.c: Removed 'dataptr' from 'struct tcp_seg' and

+
+  2010-11-21: Simon Goldschmidt
+  * dhcp.c/.h: Added a function to deallocate the struct dhcp from a netif
+    (fixes bug #31525).
+
+  2010-07-12: Simon Goldschmidt (patch by Stephane Lesage)
+  * ip.c, udp.c/.h, pbuf.h, sockets.c: task #10495: Added support for
+    IP_MULTICAST_LOOP at socket- and raw-API level.
+
+  2010-06-16: Simon Goldschmidt
+  * ip.c: Added an optional define (LWIP_IP_ACCEPT_UDP_PORT) that can allow
+    link-layer-addressed UDP traffic to be received while a netif is down (just
+    like DHCP during configuration)
+
+  2010-05-22: Simon Goldschmidt
+  * many many files: bug #27352: removed packing from ip_addr_t, the packed
+    version is now only used in protocol headers. Added global storage for
+    current src/dest IP address while in input functions.
+
+  2010-05-16: Simon Goldschmidt
+  * def.h: task #10391: Add preprocessor-macros for compile-time htonl
+    calculation (and use them throughout the stack where applicable)
+
+  2010-05-16: Simon Goldschmidt
+  * opt.h, memp_std.h, memp.c, ppp_oe.h/.c: PPPoE now uses its own MEMP pool
+    instead of the heap (moved struct pppoe_softc from ppp_oe.c to ppp_oe.h)
+
+  2010-05-16: Simon Goldschmidt
+  * opt.h, memp_std.h, dns.h/.c: DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses its own
+    MEMP pool instead of the heap
+
+  2010-05-13: Simon Goldschmidt
+  * tcp.c, udp.c: task #6995: Implement SO_REUSEADDR (correctly), added
+    new option SO_REUSE_RXTOALL to pass received UDP broadcast/multicast
+    packets to more than one pcb.
+
+  2010-05-02: Simon Goldschmidt
+  * netbuf.h/.c, sockets.c, api_msg.c: use checksum-on-copy for sending
+    UDP data for LWIP_NETIF_TX_SINGLE_PBUF==1
+
+  2010-04-30: Simon Goldschmidt
+  * udp.h/.c, pbuf.h/.c: task #6849: added udp_send(_to/_if) functions that
+    take a precalculated checksum, added pbuf_fill_chksum() to copy data
+    into a pbuf and at the same time calculating the checksum for that data
+
+  2010-04-29: Simon Goldschmidt
+  * ip_addr.h, etharp.h/.c, autoip.c: Create overridable macros for copying
+    2-byte-aligned IP addresses and MAC addresses
+
+  2010-04-28: Patch by Bill Auerbach
+  * ip.c: Inline generating IP checksum to save a function call
+
+  2010-04-14: Simon Goldschmidt
+  * tcpip.h/.c, timers.c: Added an overridable define to get informed when the
+    tcpip_thread processes messages or timeouts to implement a watchdog.
+
+  2010-03-28: Simon Goldschmidt
+  * ip_frag.c: create a new (contiguous) PBUF_RAM for every outgoing
+    fragment if LWIP_NETIF_TX_SINGLE_PBUF==1
+
+  2010-03-27: Simon Goldschmidt
+  * etharp.c: Speedup TX by moving code from find_entry to etharp_output/
+    etharp_query to prevent unnecessary function calls (inspired by
+    patch #7135).
+
+  2010-03-20: Simon Goldschmidt
+  * opt.h, tcpip.c/.h: Added an option to disable tcpip_(un)timeout code
+    since the linker cannot do this automatically to save space.
+
+  2010-03-20: Simon Goldschmidt
+  * opt.h, etharp.c/.h: Added support for static ARP table entries
+
+  2010-03-14: Simon Goldschmidt

+    when creating TCP segments, not when (re-)transmitting them.
+
+  2010-03-07: Simon Goldschmidt
+  * sockets.c: bug #28775 (select/event_callback: only check select_cb_list
+    on change) plus use SYS_LIGHTWEIGHT_PROT to protect the select code.
+    This should speed up receiving data on sockets as the select code in
+    event_callback is only executed when select is waiting.
+
+  2010-03-06: Simon Goldschmidt
+  * tcp_out.c: task #7013 (Create option to have all packets delivered to
+    netif->output in one piece): Always copy to try to create single pbufs
+    in tcp_write.
+
+  2010-03-06: Simon Goldschmidt
+  * api.h, api_lib.c, sockets.c: task #10167 (sockets: speed up TCP recv
+    by not allocating a netbuf): added function netconn_recv_tcp_pbuf()
+    for tcp netconns to receive pbufs, not netbufs; use that function
+    for tcp sockets.
+
+  2010-03-05: Jakob Ole Stoklundsen / Simon Goldschmidt
+  * opt.h, tcp.h, tcp_impl.h, tcp.c, tcp_in.c, tcp_out.c: task #7040:
+    Work on tcp_enqueue: Don't waste memory when chaining segments,
+    added option TCP_OVERSIZE to prevent creating many small pbufs when
+    calling tcp_write with many small blocks of data. Instead, pbufs are
+    allocated larger than needed and the space is used for later calls to
+    tcp_write.
+
+  2010-02-21: Simon Goldschmidt
+  * stats.c/.h: Added const char* name to mem- and memp-stats for easier
+    debugging.
+
+  2010-02-21: Simon Goldschmidt
+  * tcp.h (and usages), added tcp_impl.h: Splitted API and internal
+    implementation of tcp to make API usage cleare to application programmers
+
+  2010-02-14: Simon Goldschmidt/Stephane Lesage
+  * ip_addr.h: Improved some defines working on ip addresses, added faster
+    macro to copy addresses that cannot be NULL
+
+  2010-02-13: Simon Goldschmidt
+  * api.h, api_lib.c, api_msg.c, sockets.c: task #7865 (implement non-
+    blocking send operation)
+
+  2010-02-12: Simon Goldschmidt
+  * sockets.c/.h: Added a minimal version of posix fctl() to have a
+    standardised way to set O_NONBLOCK for nonblocking sockets.
+
+  2010-02-12: Simon Goldschmidt
+  * dhcp.c/.h, autoip.c/.h: task #10139 (Prefer statically allocated
+    memory): added autoip_set_struct() and dhcp_set_struct() to let autoip
+    and dhcp work with user-allocated structs instead of callin mem_malloc
+
+  2010-02-12: Simon Goldschmidt/Jeff Barber
+  * tcp.c/h: patch #6865 (SO_REUSEADDR for TCP): if pcb.so_options has
+    SOF_REUSEADDR set, allow binding to endpoint in TIME_WAIT
+
+  2010-02-12: Simon Goldschmidt
+  * sys layer: task #10139 (Prefer statically allocated memory): converted
+    mbox and semaphore functions to take pointers to sys_mbox_t/sys_sem_t;
+    converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
+    task #7212: Add Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX
+    to let sys.h use binary semaphores instead of mutexes - as before)
+
+  2010-02-09: Simon Goldschmidt (Simon Kallweit)
+  * timers.c/.h: Added function sys_restart_timeouts() from patch #7085
+    (Restart system timeout handling)
+
+  2010-02-09: Simon Goldschmidt
+  * netif.c/.h, removed loopif.c/.h: task #10153 (Integrate loopif into
+    netif.c) - loopif does not have to be created by the port any more,
+    just define LWIP_HAVE_LOOPIF to 1.
+
+  2010-02-08: Simon Goldschmidt
+  * inet.h, ip_addr.c/.h: Added reentrant versions of inet_ntoa/ipaddr_ntoa
+    inet_ntoa_r/ipaddr_ntoa_r
+
+  2010-02-08: Simon Goldschmidt
+  * netif.h: Added netif_s/get_igmp_mac_filter() macros
+
+  2010-02-05: Simon Goldschmidt
+  * netif.h: Added function-like macros to get/set the hostname on a netif
+
+  2010-02-04: Simon Goldschmidt
+  * nearly every file: Replaced struct ip_addr by typedef ip_addr_t to
+    make changing the actual implementation behind the typedef easier.
+
+  2010-02-01: Simon Goldschmidt
+  * opt.h, memp_std.h, dns.h, netdb.c, memp.c: Let netdb use a memp pool
+    for allocating memory when getaddrinfo() is called.
+
+  2010-01-31: Simon Goldschmidt
+  * dhcp.h, dhcp.c: Reworked the code that parses DHCP options: parse
+    them once instead of parsing for every option. This also removes
+    the need for mem_malloc from dhcp_recv and makes it possible to
+    correctly retrieve the BOOTP file.
+
+  2010-01-30: simon Goldschmidt
+  * sockets.c: Use SYS_LIGHTWEIGHT_PROT instead of a semaphore to protect
+    the sockets array.
+
+  2010-01-29: Simon Goldschmidt (patch by Laura Garrett)
+  * api.h, api_msg.c, sockets.c: Added except set support in select
+    (patch #6860)
+
+  2010-01-29: Simon Goldschmidt (patch by Laura Garrett)
+  * api.h, sockets.h, err.h, api_lib.c, api_msg.c, sockets.c, err.c:
+    Add non-blocking support for connect (partly from patch #6860),
+    plus many cleanups in socket & netconn API.
+
+  2010-01-27: Simon Goldschmidt
+  * opt.h, tcp.h, init.c, api_msg.c: Added TCP_SNDQUEUELOWAT corresponding
+    to TCP_SNDLOWAT and added tcp_sndqueuelen() - this fixes bug #28605
+
+  2010-01-26: Simon Goldschmidt
+  * snmp: Use memp pools for snmp instead of the heap; added 4 new pools.
+
+  2010-01-14: Simon Goldschmidt
+  * ppp.c/.h: Fixed bug #27856: PPP: Set netif link- and status-callback
+    by adding ppp_set_netif_statuscallback()/ppp_set_netif_linkcallback()
+
+  2010-01-13: Simon Goldschmidt
+  * mem.c: The heap now may be moved to user-defined memory by defining
+    LWIP_RAM_HEAP_POINTER as a void pointer to that memory's address
+    (patch #6966 and bug #26133)
+
+  2010-01-10: Simon Goldschmidt (Bill Auerbach)
+  * opt.h, memp.c: patch #6822 (Add option to place memory pools in
+    separate arrays)
+
+  2010-01-10: Simon Goldschmidt

+    LWIP_RAND() for lwip-wide randomization (to be defined in cc.h)
+
+  2009-12-31: Simon Goldschmidt
+  * tcpip.c, init.c, memp.c, sys.c, memp_std.h, sys.h, tcpip.h
+    added timers.c/.h: Separated timer implementation from semaphore/mbox
+    implementation, moved timer implementation to timers.c/.h, timers are
+    now only called from tcpip_thread or by explicitly checking them.
+    (TASK#7235)
+
+  2009-12-27: Simon Goldschmidt
+  * opt.h, etharp.h/.c, init.c, tcpip.c: Added an additional option
+    LWIP_ETHERNET to support ethernet without ARP (necessary for pure PPPoE)
+
+
+  ++ Bugfixes:
+

+    use EALRADY instead of -1
+
+  2011-03-13: Simon Goldschmidt
+  * api_lib.c: netconn_accept: return ERR_ABRT instead of ERR_CLSD if the

+
+  2010-01-31: Simon Goldschmidt
+  * netif.c: Don't call the link-callback from netif_set_up/down() since
+    this invalidly retriggers DHCP.
+
+  2010-01-29: Simon Goldschmidt
+  * ip_addr.h, inet.h, def.h, inet.c, def.c, more: Cleanly separate the
+    portability file inet.h and its contents from the stack: moved htonX-
+    functions to def.h (and the new def.c - they are not ipv4 dependent),
+    let inet.h depend on ip_addr.h and not the other way round.

+    hosts table. New configuration options DNS_LOCAL_HOSTLIST and
+    DNS_LOCAL_HOSTLIST_IS_DYNAMIC. Also, DNS_LOOKUP_LOCAL_EXTERN() can be defined
+    as an external function for lookup.
+
+  2009-04-15 Simon Goldschmidt
+  * dhcp.c: patch #6763: Global DHCP XID can be redefined to something more unique
+
+  2009-03-31 Kieran Mansley
+  * tcp.c, tcp_out.c, tcp_in.c, sys.h, tcp.h, opts.h: add support for

+
+  2009-02-11 Simon Goldschmidt (suggested by Gottfried Spitaler)
+  * opt.h, memp.h/.c: added MEMP_MEM_MALLOC to use mem_malloc/mem_free instead
+    of the pool allocator (can save code size with MEM_LIBC_MALLOC if libc-malloc
+    is otherwise used)
+
+  2009-01-28 Jonathan Larmour (suggested by Bill Bauerbach)
+  * ipv4/inet_chksum.c, ipv4/lwip/inet_chksum.h: inet_chksum_pseudo_partial()

+
+  2008-12-03 Simon Goldschmidt (base on patch from Luca Ceresoli)
+  * autoip.c: checked in (slightly modified) patch #6683: Customizable AUTOIP

+  * mem.c, opt.h, stats.h: fixed bug #21433: Calling mem_free/pbuf_free from
+    interrupt context isn't safe: LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT allows
+    mem_free to run between mem_malloc iterations. Added illegal counter for
+    mem stats.
+
+  2008-06-27 Simon Goldschmidt
+  * stats.h/.c, some other files: patch #6483: stats module improvement:
+    Added defines to display each module's statistic individually, added stats

+
+  2008-06-17 Simon Goldschmidt

+    modified version of patch # 6370: Moved loopif code to netif.c so that
+    loopback traffic is supported on all netifs (all local IPs).
+    Added option to limit loopback packets for each netifs.

+    SO(F)_BROADCAST filter for all API layers. Avoid the unindented reception
+    of broadcast packets even when this option wasn't set. Port maintainers
+    which want to enable this filter have to set IP_SOF_BROADCAST=1 in opt.h.
+    If you want this option also filter broadcast on recv operations, you also
+    have to set IP_SOF_BROADCAST_RECV=1 in opt.h.

+
+  2008-03-26 Simon Goldschmidt
+  * tcp_in.c, tcp.c: fixed bug #22249: division by zero could occur if a remote

+
+
+(STABLE-1.3.0)
+
+  ++ New features:
+
+  2008-03-10 Jonathan Larmour
+  * inet_chksum.c: Allow choice of one of the sample algorithms to be
+    made from lwipopts.h. Fix comment on how to override LWIP_CHKSUM.
+
+  2008-01-22 Frédéric Bernon
+  * tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in 
+    TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names.
+
+  2008-01-14 Frédéric Bernon
+  * rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675 "Enable
+    to refuse data on a TCP_EVENT_RECV call". Important, behavior changes for the
+    tcp_recv callback (see rawapi.txt).
+
+  2008-01-14 Frédéric Bernon, Marc Chaland
+  * ip.c: Integrate patch #6369" ip_input : checking before realloc".
+  
+  2008-01-12 Frédéric Bernon
+  * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
+    netconn::sem per netconn::op_completed like suggested for the task #7490
+    "Add return value to sys_mbox_post".
+
+  2008-01-12 Frédéric Bernon
+  * api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE,
+    DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues
+    sizes), like suggested for the task #7490 "Add return value to sys_mbox_post".
+
+  2008-01-10 Frédéric Bernon
+  * tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490
+    "Add return value to sys_mbox_post". tcpip_callback is always defined as
+    "blocking" ("block" parameter = 1).
+
+  2008-01-10 Frédéric Bernon
+  * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
+    netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490
+    "Add return value to sys_mbox_post".
+
+  2008-01-05 Frédéric Bernon
+  * sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h:
+    Introduce changes for task #7490 "Add return value to sys_mbox_post" with some
+    modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
+    indicate the number of pointers query by the mailbox. There is three defines
+    in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the 
+    netconn::acceptmbox. Port maintainers, you can decide to just add this new 
+    parameter in your implementation, but to ignore it to keep the previous behavior.
+    The new sys_mbox_trypost function return a value to know if the mailbox is
+    full or if the message is posted. Take a look to sys_arch.txt for more details.
+    This new function is used in tcpip_input (so, can be called in an interrupt
+    context since the function is not blocking), and in recv_udp and recv_raw.
+
+  2008-01-04 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
+  * rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c,
+    tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the
+    "backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add
+    documentation in the rawapi.txt file.
+
+  2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
+  * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer
+
+  2007-12-31 Frédéric Bernon, Luca Ceresoli
+  * autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets
+    in autoip". The change in etharp_raw could be removed, since all calls to
+    etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
+    wrong in the future.
+
+  2007-12-30 Frédéric Bernon, Tom Evans
+  * ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address
+    Filtering" reported by Tom Evans.
+
+  2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
+  * tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
+    sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
+    applications have to call 'tcp_accepted(pcb)' in their accept callback to
+    keep accepting new connections.
+
+  2007-12-13 Frédéric Bernon
+  * api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"
+    by err_t type. Add a new err_t code "ERR_INPROGRESS".
+
+  2007-12-12 Frédéric Bernon
+  * dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
+    are the one which have ram usage.
+
+  2007-12-05 Frédéric Bernon
+  * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
+    set of variables (=0) or a local one (=1). In this last case, your port should
+    provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
+    which have to do a copy of "h" and return a pointer ont the "per-thread" copy.
+
+  2007-12-03 Simon Goldschmidt
+  * ip.c: ip_input: check if a packet is for inp first before checking all other
+    netifs on netif_list (speeds up packet receiving in most cases)
+
+  2007-11-30 Simon Goldschmidt
+  * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
+    UDP: move a (connected) pcb selected for input to the front of the list of
+    pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
+    a packet.
+
+  2007-11-28 Simon Goldschmidt
+  * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
+
+  2007-11-25 Simon Goldschmidt
+  * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
+    algorithm.
+
+  2007-11-24 Simon Goldschmidt
+  * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
+    to the new file netdb.c; included lwip_getaddrinfo.
+
+  2007-11-21 Simon Goldschmidt
+  * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
+    based on the MTU of the netif used to send. Enabled by default. Disable by
+    setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
+
+  2007-11-19 Frédéric Bernon
+  * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
+    received match the name query), implement DNS_USES_STATIC_BUF (the place where
+    copy dns payload to parse the response), return an error if there is no place
+    for a new query, and fix some minor problems.
+
+  2007-11-16 Simon Goldschmidt
+  * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
+    removed files: core/inet.c, core/inet6.c
+    Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
+    inet and chksum part; changed includes in all lwIP files as appropriate
+
+  2007-11-16 Simon Goldschmidt
+  * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
+    dns resolver function for netconn api (netconn_gethostbyname) and socket api
+    (gethostbyname/gethostbyname_r).
+
+  2007-11-15 Jim Pettinato, Frédéric Bernon
+  * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
+    requests with RAW api interface. Initialization is done in lwip_init() with
+    build time options. DNS timer is added in tcpip_thread context. DHCP can set
+    DNS server ip addresses when options are received. You need to set LWIP_DNS=1
+    in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
+    some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
+    list with points to improve.
+
+  2007-11-06 Simon Goldschmidt
+  * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
+    enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
+    for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
+
+  2007-11-06 Simon Goldschmidt
+  * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
+    core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
+    implementation from netconn api applications.
+
+  2007-11-03 Frédéric Bernon
+  * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
+    RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
+    by default). Netconn API users can use the netconn_recv_bufsize macro to access
+    it. This is a first release which have to be improve for TCP. Note it used the
+    netconn::recv_avail which need to be more "thread-safe" (note there is already
+    the problem for FIONREAD with lwip_ioctl/ioctlsocket).
+
+  2007-11-01 Frédéric Bernon, Marc Chaland
+  * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:
+    Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
+    layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
+    layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
+    Note that previous "copy" parameter for "write" APIs is now called "apiflags".
+
+  2007-10-24 Frédéric Bernon
+  * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than 
+    TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
+    some code (like we have talk in "patch #5919 : Create compile switch to remove
+    select code"), but it could be done later.
+
+  2007-10-08 Simon Goldschmidt
+  * many files: Changed initialization: many init functions are not needed any
+    more since we now rely on the compiler initializing global and static
+    variables to zero!
+
+  2007-10-06 Simon Goldschmidt
+  * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
+    to enqueue the received pbufs so that multiple packets can be reassembled
+    simultaneously and no static reassembly buffer is needed.
+
+  2007-10-05 Simon Goldschmidt
+  * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
+    all netifs (or ports) can use it.
+
+  2007-10-05 Frédéric Bernon
+  * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the 
+    common function to reduce a little bit the footprint (for all functions using
+    only the "netif" parameter).
+
+  2007-10-03 Frédéric Bernon
+  * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
+    netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
+    a little bit the footprint (for all functions using only the "netif" parameter).
+
+  2007-09-15 Frédéric Bernon
+  * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
+    option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
+    netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
+    IP_MULTICAST_TTL and IP_MULTICAST_IF.
+
+  2007-09-10 Frédéric Bernon
+  * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
+    even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
+    each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
+    decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
+    call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
+    or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
+    This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
+    snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
+    when it's queried (any direct call to "sysuptime" is changed by a call to 
+    snmp_get_sysuptime).
+
+  2007-09-09 Frédéric Bernon, Bill Florac
+  * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
+    and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
+    if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
+    igmp_report_groups() is now called inside netif_set_link_up() (need to have
+    LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait
+    the next query message to receive the matching multicast streams).
+
+  2007-09-08 Frédéric Bernon
+  * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
+    IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
+    Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).
+    Enable to access to these fields with LWIP_TCP=0.
+
+  2007-09-05 Frédéric Bernon
+  * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,
+    ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
+    LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
+    Be careful, disabling ICMP make your product non-compliant to RFC1122, but
+    help to reduce footprint, and to reduce "visibility" on the Internet.
+
+  2007-09-05 Frédéric Bernon, Bill Florac
+  * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list
+    for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new
+    parameters have to be provided: a task name, and a task stack size. For this
+    one, since it's platform dependant, you could define the best one for you in
+    your lwipopts.h. For port maintainers, you can just add these new parameters
+    in your sys_arch.c file, and but it's not mandatory, use them in your OS
+    specific functions.
+
+  2007-09-05 Frédéric Bernon
+  * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings
+    inside init.c for task #7142 "Sanity check user-configurable values".
+
+  2007-09-04 Frédéric Bernon, Bill Florac
+  * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by
+    memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
+    value). It will avoid potential fragmentation problems, use a counter to know
+    how many times a group is used on an netif, and free it when all applications
+    leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
+    check if LWIP_IGMP!=0).
+
+  2007-09-03 Frédéric Bernon
+  * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
+    Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
+    the netif's "init" function). Use the "imr_interface" field (for socket layer)
+    and/or the "interface" field (for netconn layer), for join/leave operations.
+    The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
+    This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).
+
+  2007-08-30 Frédéric Bernon
+  * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
+    from api/api_lib". Now netbuf API is independant of netconn, and can be used
+    with other API (application based on raw API, or future "socket2" API). Ports
+    maintainers just have to add src/api/netbuf.c in their makefile/projects.
+
+  2007-08-30 Frédéric Bernon, Jonathan Larmour
+  * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
+    user-configurable values".
+
+  2007-08-29 Frédéric Bernon
+  * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
+    igmp_start is call inside netif_add. Now, igmp initialization is in the same
+    spirit than the others modules. Modify some IGMP debug traces.
+
+  2007-08-29 Frédéric Bernon
+  * Add init.h, init.c, Change opt.h, tcpip.c: Task  #7213 "Add a lwip_init function"
+    Add lwip_init function to regroup all modules initializations, and to provide
+    a place to add code for task #7142 "Sanity check user-configurable values".
+    Ports maintainers should remove direct initializations calls from their code,
+    and add init.c in their makefiles. Note that lwip_init() function is called
+    inside tcpip_init, but can also be used by raw api users since all calls are
+    disabled when matching options are disabled. Also note that their is new options
+    in opt.h, you should configure in your lwipopts.h (they are enabled per default).
+
+  2007-08-26 Marc Boucher
+  * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL
+    since they can under certain circumstances be called with an invalid conn
+    pointer after the connection has been closed (and conn has been freed). 
+
+  2007-08-25 Frédéric Bernon (Artem Migaev's Patch)
+  * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".
+    Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
+
+  2007-08-22 Frédéric Bernon
+  * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK
+    to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.
+
+  2007-08-22 Frédéric Bernon
+  * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
+    ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the 
+    name is tcpip_input (we keep the name of 1.2.0 function).
+
+  2007-08-17 Jared Grubb
+  * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool 
+    settings into new memp_std.h and optional user file lwippools.h. This adds
+    more dynamic mempools, and allows the user to create an arbitrary number of
+    mempools for mem_malloc.
+
+  2007-08-16 Marc Boucher
+  * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
+    otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
+    close the connection.
+
+  2007-08-16 Marc Boucher
+  * sockets.c: lwip_accept(): check netconn_peer() error return.
+
+  2007-08-16 Marc Boucher
+  * mem.c, mem.h: Added mem_calloc().
+
+  2007-08-16 Marc Boucher
+  * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
+    for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
+    and starving other message types.
+    Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API
+
+  2007-08-16 Marc Boucher
+  * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
+    type and flgs (later renamed to flags).
+    Use enum pbuf_flag as pbuf_type.  Renumber PBUF_FLAG_*.
+    Improved lwip_recvfrom().  TCP push now propagated.
+
+  2007-08-16 Marc Boucher
+  * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
+    provided by etharp.
+
+  2007-08-16 Marc Boucher
+  * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
+    etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
+    Added PPPoE support and various PPP improvements.
+
+  2007-07-25 Simon Goldschmidt
+  * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
+    making netbuf_copy_partial use this function.
+
+  2007-07-25 Simon Goldschmidt
+  * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
+    2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
+    other stacks.
+
+  2007-07-13 Jared Grubb (integrated by Frédéric Bernon)
+  * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
+    a link callback in the netif struct, and functions to handle it. Be carefull
+    for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
+    if you want to be sure to be compatible with future changes...
+
+  2007-06-30 Frédéric Bernon
+  * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
+
+  2007-06-21 Simon Goldschmidt
+  * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
+    LWIP_AUTOIP =0 and =1 to remove redundant code.
+
+  2007-06-21 Simon Goldschmidt
+  * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
+    MEM_USE_POOLS to use 4 pools with different sized elements instead of a
+    heap. This both prevents memory fragmentation and gives a higher speed
+    at the cost of more memory consumption. Turned off by default.
+
+  2007-06-21 Simon Goldschmidt
+  * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
+    netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
+    int to be able to send a bigger buffer than 64K with one time (mainly
+    used from lwip_send).
+
+  2007-06-21 Simon Goldschmidt
+  * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
+    into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
+
+  2007-06-21 Simon Goldschmidt
+  * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
+    netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
+    changes on low memory or empty send-buffer.
+
+  2007-06-18 Simon Goldschmidt
+  * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
+    of 6 to avoid loading netif->hwaddr_len every time (since this file is only
+    used for ethernet and struct eth_addr already had a defined length of 6).
+
+  2007-06-17 Simon Goldschmidt
+  * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
+    to disable UDP checksum generation on transmit.
+
+  2007-06-13 Frédéric Bernon, Simon Goldschmidt
+  * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
+    pointers or parameters, and let the possibility to redefined it in cc.h. Use
+    this macro to check "conn" parameter in api_msg.c functions.
+
+  2007-06-11 Simon Goldschmidt
+  * sockets.c, sockets.h: Added UDP lite support for sockets
+
+  2007-06-10 Simon Goldschmidt
+  * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
+    by default) to switch off UDP-Lite support if not needed (reduces udp.c code
+    size)
+
+  2007-06-09 Dominik Spies (integrated by Frédéric Bernon)
+  * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
+    AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
+    LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
+    (see TODO mark in the source code).
+
+  2007-06-09 Simon Goldschmidt
+  * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
+    etharp_output() to match netif->output so etharp_output() can be used
+    directly as netif->output to save one function call.
+
+  2007-06-08 Simon Goldschmidt
+  * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
+    NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
+    added initialization of those to ethernetif, slipif and loopif.
+
+  2007-05-18 Simon Goldschmidt
+  * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
+    (defaulting to off for now) that can be set to 0 to send fragmented
+    packets by passing PBUF_REFs down the stack.
+
+  2007-05-23 Frédéric Bernon
+  * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
+    connections, such present in patch #5959.
+
+  2007-05-23 Frédéric Bernon
+  * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
+    code in only one part...
+
+  2007-05-18 Simon Goldschmidt
+  * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
+    elements to overflow. This is achieved by adding some bytes before and after
+    each pool element (increasing their size, of course), filling them with a
+    prominent value and checking them on freeing the element.
+    Set it to 2 to also check every element in every pool each time memp_malloc()
+    or memp_free() is called (slower but more helpful).
+
+  2007-05-10 Simon Goldschmidt
+  * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
+    PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
+    code size.
+
+  2007-05-11 Frédéric Bernon
+  * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
+    Include a function pointer instead of a table index in the message to reduce
+    footprint. Disable some part of lwip_send and lwip_sendto if some options are
+    not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
+
+  2007-05-10 Simon Goldschmidt
+  * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
+    \ extern "C" {' in all header files. Now you can write your application using
+    the lwIP stack in C++ and simply #include the core files. Note I have left
+    out the netif/ppp/*h header files for now, since I don't know which files are
+    included by applications and which are for internal use only.
+
+  2007-05-09 Simon Goldschmidt
+  * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
+    memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
+    situations where some compilers might inline the copy and save a function
+    call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().
+
+  2007-05-08 Simon Goldschmidt
+  * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
+    to be overriden in case the C-library malloc implementation is not protected
+    against concurrent access.
+
+  2007-05-04 Simon Goldschmidt (Atte Kojo)
+  * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
+    multiple packets to the same host.
+
+  2007-05-04 Frédéric Bernon, Jonathan Larmour
+  * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
+    to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
+    netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
+    sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
+    Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
+    these fields are now renamed "addr" & "port".
+
+  2007-04-11 Jonathan Larmour
+  * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
+    sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
+    with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
+    by the port in sys_arch.h if desired.
+
+  2007-04-06 Frédéric Bernon, Simon Goldschmidt
+  * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
+    allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
+    clients, using new functions from netifapi.h. Disable as default (no port change to do).
+
+  2007-04-05 Frédéric Bernon
+  * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.
+
+  2007-04-04 Simon Goldschmidt
+  * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
+    use this for and architecture-independent form to tell the compiler you intentionally
+    are not using this variable. Can be overriden in cc.h.
+
+  2007-03-28 Frédéric Bernon
+  * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
+    define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
+    string, point on one of your's ethernetif field, or alloc a string you will free yourself).
+    It will be used by DHCP to register a client hostname, but can also be use when you call
+    snmp_set_sysname.
+
+  2007-03-28 Frédéric Bernon
+  * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to 
+    initialize a network interface's flag with. It tell this interface is an ethernet
+    device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
+    Support for IPv4" section 4.6) when interface is "up" with netif_set_up().
+
+  2007-03-26 Frédéric Bernon, Jonathan Larmour
+  * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
+    time if you only use PPP or SLIP. The default is enable. Note we don't have to call 
+    etharp_init in your port's initilization sequence if you use tcpip.c, because this call
+    is done in tcpip_init function.
+
+  2007-03-22 Frédéric Bernon
+  * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
+    new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
+    your lwipopts.h. More, unused counters are not defined in the stats structs, and not 
+    display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
+    but never used. Fix msg_in.c with the correct #if test for a stat display.
+
+  2007-03-21 Kieran Mansley
+  * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com). 
+    Provides callback on netif up/down state change.
+
+  2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds
+  * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c,
+    ip.c, netif.h, tcpip.c, opt.h:
+    New configuration option LWIP_IGMP to enable IGMP processing. Based on only one 
+    filter per all network interfaces. Declare a new function in netif to enable to
+    control the MAC filter (to reduce lwIP traffic processing).
+
+  2007-03-11 Frédéric Bernon
+  * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
+    be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
+    unless you know what you're doing (default are RFC1122 compliant). Note
+    that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.
+
+  2007-03-08 Frédéric Bernon
+  * tcp.h: Keepalive values can be configured at compile time, but don't change
+    this unless you know what you're doing (default are RFC1122 compliant).
+
+  2007-03-08 Frédéric Bernon
+  * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h:
+    Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO
+    on UDP sockets/netconn.
+
+  2007-03-08 Simon Goldschmidt
+  * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time.
+
+  2007-03-06 Frédéric Bernon
+  * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h: 
+    Implement SO_RCVTIMEO on UDP sockets/netconn.
+
+  2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt)
+  * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated
+    on the stack and remove the API msg type from memp
+
+  2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
+  * sockets.h, sockets.c: Move socket initialization to new
+    lwip_socket_init() function.
+    NOTE: this changes the API with ports. Ports will have to be
+    updated to call lwip_socket_init() now.
+
+  2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
+  * api_lib.c: Use memcpy in netbuf_copy_partial.
+
+
+  ++ Bug fixes:
+
+  2008-03-17 Frédéric Bernon, Ed Kerekes
+  * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
+    some problems to fill the IP header on some targets, use now the
+    ip.h macros to do it).
+
+  2008-03-13 Frédéric Bernon
+  * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
+    (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
+    TCP connection caused a crash. Note that using (lwip_)recvfrom
+    like this is a bit slow and that using (lwip)getpeername is the
+    good lwip way to do it (so, using recv is faster on tcp sockets).
+
+  2008-03-12 Frédéric Bernon, Jonathan Larmour
+  * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's
+    recv_raw() does not consume data", and the ping sample (with
+    LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom
+    returned the IP payload, without the IP header).
+
+  2008-03-04 Jonathan Larmour
+  * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors
+  and/or warnings on some systems where mem_size_t and size_t differ.
+  * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc.
+
+  2008-03-04 Kieran Mansley (contributions by others) 
+  * Numerous small compiler error/warning fixes from contributions to
+    mailing list after 1.3.0 release candidate made.
+
+  2008-01-25 Cui hengbin (integrated by Frédéric Bernon)
+  * dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures.
+
+  2008-01-15 Kieran Mansley
+  * tcp_out.c: BUG20511.  Modify persist timer to start when we are
+    prevented from sending by a small send window, not just a zero
+    send window.
+
+  2008-01-09 Jonathan Larmour
+  * opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid
+    conflict with Linux system headers.
+
+  2008-01-06 Jonathan Larmour
+  * dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP
+    address entirely on receiving a DHCPNAK, and restarting discovery.
+
+  2007-12-21 Simon Goldschmidt
+  * sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail
+    is not protected" by using new macros for interlocked access to modify/test
+    netconn->recv_avail.
+
+  2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev)
+  * tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state)
+
+  2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
+  * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling
+    of silly window avoidance and prevent lwIP from shrinking the window)
+
+  2007-12-04 Simon Goldschmidt
+  * tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last
+    data packet was lost): add assert that all segment lists are empty in
+    tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED
+    state from LAST_ACK in tcp_process
+
+  2007-12-02 Simon Goldschmidt
+  * sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET
+    If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now
+    has to be set to 0 in lwipopts.h
+
+  2007-12-02 Simon Goldschmidt
+  * api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always
+    allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen
+    netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox.
+    This is a fix for thread-safety and allocates all items needed for a netconn
+    when the netconn is created.
+
+  2007-11-30 Simon Goldschmidt
+  * udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple
+    netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed
+    to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same
+    port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address)
+
+  2007-11-27 Simon Goldschmidt
+  * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by
+    letting ip_route only use netifs that are up.
+
+  2007-11-27 Simon Goldschmidt
+  * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF
+    and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and
+    sockets block most operations once they have seen a fatal error.
+
+  2007-11-27 Simon Goldschmidt
+  * udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the
+    netif to send as an argument (to be able to send on netifs that are down).
+
+  2007-11-26 Simon Goldschmidt
+  * tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs
+    arrive out-of-order
+
+  2007-11-21 Simon Goldschmidt
+  * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early
+    Fixed the nagle algorithm; nagle now also works for all raw API applications
+    and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY'
+
+  2007-11-12 Frédéric Bernon
+  * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most
+    of the netconn_peer and netconn_addr processing is done inside tcpip_thread
+    context in do_getaddr.
+
+  2007-11-10 Simon Goldschmidt
+  * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
+    happen any time). Now the packet simply isn't enqueued when out of memory.
+
+  2007-11-01 Simon Goldschmidt
+  * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
+    TCP_MSS if that is smaller) as long as no MSS option is received from the
+    remote host.
+
+  2007-11-01 Simon Goldschmidt
+  * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
+    is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
+    sending our configured TCP_MSS instead of the one received).
+
+  2007-11-01 Simon Goldschmidt
+  * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
+    calculated based on the configured TCP_MSS, not on the MSS option received
+    with SYN+ACK.
+
+  2007-10-09 Simon Goldschmidt
+  * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
+    short and also was generated wrong if checksum coverage != tot_len;
+    receive: checksum was calculated wrong if checksum coverage != tot_len
+
+  2007-10-08 Simon Goldschmidt
+  * mem.c: lfree was not updated in mem_realloc!
+
+  2007-10-07 Frédéric Bernon
+  * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
+    crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
+    this change cause an API breakage for netconn_addr, since a parameter
+    type change. Any compiler should cause an error without any changes in
+    yours netconn_peer calls (so, it can't be a "silent change"). It also
+    reduce a little bit the footprint for socket layer (lwip_getpeername &
+    lwip_getsockname use now a common lwip_getaddrname function since 
+    netconn_peer & netconn_addr have the same parameters).
+
+  2007-09-20 Simon Goldschmidt
+  * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
+    by checking  tcp_tw_pcbs also
+
+  2007-09-19 Simon Goldschmidt
+  * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
+
+  2007-09-15 Mike Kleshov
+  * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
+
+  2007-09-06 Frédéric Bernon
+  * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
+    it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
+    already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
+    if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.
+
+  2007-08-30 Frédéric Bernon
+  * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces, 
+    and fix some coding style.
+
+  2007-08-28 Frédéric Bernon
+  * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
+    kind of packets. These packets are considered like Ethernet packets (payload 
+    pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets 
+    are considered like IP packets (payload pointing to iphdr).
+
+  2007-08-27 Frédéric Bernon
+  * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
+    problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
+    and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
+
+  2007-08-24 Kieran Mansley
+  * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy
+    compiler (Paradigm C++)
+
+  2007-08-09 Frédéric Bernon, Bill Florac
+  * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
+    Introduce IGMP_STATS to centralize statistics management.
+
+  2007-08-09 Frédéric Bernon, Bill Florac
+  * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
+    packet on a udp pcb binded on an netif's IP address, and not on "any".
+
+  2007-08-09 Frédéric Bernon, Bill Florac
+  * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
+    This is mainly on using lookup/lookfor, and some coding styles...
+
+  2007-07-26 Frédéric Bernon (and "thedoctor")
+  * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages.
+
+  2007-07-25 Simon Goldschmidt
+  * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
+    tcp_output fails in tcp_close, the code in do_close_internal gets simpler
+    (tcp_output is called again later from tcp timers).
+
+  2007-07-25 Simon Goldschmidt
+  * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
+    copy_from_pbuf, which illegally modified the given pbuf.
+
+  2007-07-25 Simon Goldschmidt
+  * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs:
+    changed snd_queuelen++ to snd_queuelen += pbuf_clen(p).
+
+  2007-07-24 Simon Goldschmidt
+  * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the
+    correct state (must be CLOSED).
+
+  2007-07-13 Thomas Taranowski (commited by Jared Grubb)
+  * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed
+    allocation. It now returns NULL.
+
+  2007-07-13 Frédéric Bernon
+  * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
+    all error cases.
+
+  2007-07-13 Frédéric Bernon
+  * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed,
+    because current code doesn't follow rawapi.txt documentation.
+
+  2007-07-13 Kieran Mansley
+  * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in
+    out of sequence processing of received packets
+
+  2007-07-03 Simon Goldschmidt
+  * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
+    assumption is made that this pbuf is in one piece (i.e. not chained). These
+    assumptions clash with the possibility of converting to fully pool-based
+    pbuf implementations, where PBUF_RAM pbufs might be chained.
+
+  2007-07-03 Simon Goldschmidt
+  * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems
+    when closing tcp netconns: removed conn->sem, less context switches when
+    closing, both netconn_close and netconn_delete should safely close tcp
+    connections.
+
+  2007-07-02 Simon Goldschmidt
+  * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c,
+    tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
+    to cache ARP table indices with each pcb instead of single-entry cache for
+    the complete stack.
+
+  2007-07-02 Simon Goldschmidt
+  * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent
+    warnings when assigning to smaller types.
+
+  2007-06-28 Simon Goldschmidt
+  * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing.
+
+  2007-06-28 Simon Goldschmidt
+  * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if
+    a segment contained chained pbufs)
+
+  2007-06-28 Frédéric Bernon
+  * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
+    a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
+    possible to define this macro in your own lwipopts.h to always use C library's
+    rand(). Note that autoip_create_rand_addr doesn't use this macro.
+
+  2007-06-28 Frédéric Bernon
+  * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option
+    LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications
+    in api_lib/api_msg (use pointers and not type with table, etc...) 
+
+  2007-06-26 Simon Goldschmidt
+  * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines.
+
+  2007-06-25 Simon Goldschmidt
+  * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload
+    for udp packets with no matching pcb.
+
+  2007-06-25 Simon Goldschmidt
+  * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match
+    could get udp input packets if the remote side matched.
+
+  2007-06-13 Simon Goldschmidt
+  * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get
+    changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0.
+
+  2007-06-13 Simon Goldschmidt
+  * api_msg.c: pcb_new sets conn->err if protocol is not implemented
+    -> netconn_new_..() does not allocate a new connection for unsupported
+    protocols.
+
+  2007-06-13 Frédéric Bernon, Simon Goldschmidt
+  * api_lib.c: change return expression in netconn_addr and netconn_peer, because
+    conn->err was reset to ERR_OK without any reasons (and error was lost)...
+
+  2007-06-13 Frédéric Bernon, Matthias Weisser
+  * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename
+    MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid
+    some macro names collision with some OS macros.
+
+  2007-06-11 Simon Goldschmidt
+  * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0,
+    create checksum over the complete packet. On RX, if it's < 8 (and not 0),
+    discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both
+    UDP & UDP Lite.
+
+  2007-06-11 Srinivas Gollakota & Oleg Tyshev
+  * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags"
+    where TCP flags wasn't initialized in tcp_keepalive.
+
+  2007-06-03 Simon Goldschmidt
+  * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function
+    registered, p->payload was modified without modifying p->len if sending
+    icmp_dest_unreach() (had no negative effect but was definitively wrong).
+
+  2007-06-03 Simon Goldschmidt
+  * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp
+    re-used the input pbuf even if that didn't have enough space to include the
+    link headers. Now the space is tested and a new pbuf is allocated for the
+    echo response packet if the echo request pbuf isn't big enough.
+
+  2007-06-01 Simon Goldschmidt
+  * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread.
+
+  2007-05-23 Frédéric Bernon
+  * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
+    allocated by do_listen if success) and netconn_accept errors handling. In
+    most of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
+    by ASSERT, except for netconn_delete.
+
+  2007-05-23 Frédéric Bernon
+  * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return
+    an error code if it's impossible to fetch a pbuf on a TCP connection (and not
+    directly close the recvmbox).
+
+  2007-05-22 Simon Goldschmidt
+  * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of
+    bound but unconnected (and non-listening) tcp_pcbs.
+
+  2007-05-22 Frédéric Bernon
+  * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only
+    used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
+    sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
+    like "sys_timeout" in their application threads.
+
+  2007-05-22 Frédéric Bernon
+  * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see
+    which parameters are used by which do_xxx function, and to avoid "misusing"
+    parameters (patch #5938).
+
+  2007-05-22 Simon Goldschmidt
+  * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938:
+    changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto
+    is only 8 bits wide. This affects the api, as there, the protocol was
+    u16_t, too.
+
+  2007-05-18 Simon Goldschmidt
+  * memp.c: addition to patch #5913: smaller pointer was returned but
+    memp_memory was the same size -> did not save memory.
+
+  2007-05-16 Simon Goldschmidt
+  * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns
+    != ERR_OK.
+
+  2007-05-16 Simon Goldschmidt
+  * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same
+    as the one of the netif used for sending to prevent sending from old
+    addresses after a netif address gets changed (partly fixes bug #3168).
+
+  2007-05-16 Frédéric Bernon
+  * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work
+    with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in 
+    tcpip_init) because we have to be sure that network interfaces are already
+    added (mac filter is updated only in igmp_init for the moment).
+
+  2007-05-16 Simon Goldschmidt
+  * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls
+    into sys_arch_sem_wait calls to prevent timers from running while waiting
+    for the heap. This fixes bug #19167.
+
+  2007-05-13 Simon Goldschmidt
+  * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines
+    for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from
+    tcp.h to sockets.h.
+
+  2007-05-07 Simon Goldschmidt
+  * mem.c: Another attempt to fix bug #17922.
+
+  2007-05-04 Simon Goldschmidt
+  * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy()
+    implementation so that it can be reused (don't allocate the target
+    pbuf inside pbuf_copy()).
+
+  2007-05-04 Simon Goldschmidt
+  * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem
+    to save a little RAM (next pointer of memp is not used while not in pool).
+
+  2007-05-03 "maq"
+  * sockets.c: Fix ioctl FIONREAD when some data remains from last recv.
+    (patch #3574).
+
+  2007-04-23 Simon Goldschmidt
+  * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results
+    in NULL reference for incoming TCP packets". Loopif has to be configured
+    (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()
+    (multithreading environments, e.g. netif->input() = tcpip_input()) or
+    putting packets on a list that is fed to the stack by calling loopif_poll()
+    (single-thread / NO_SYS / polling environment where e.g.
+    netif->input() = ip_input).
+
+  2007-04-17 Jonathan Larmour
+  * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold
+    the difference between two u16_t's.
+  * sockets.h: FD_SETSIZE needs to match number of sockets, which is
+    MEMP_NUM_NETCONN in sockets.c right now.
+
+  2007-04-12 Jonathan Larmour
+  * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580).
+
+  2007-04-12 Kieran Mansley
+  * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission
+    timer is reset to fix bug#19434, with help from Oleg Tyshev.
+
+  2007-04-11 Simon Goldschmidt
+  * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than
+    previously thought need to be copied (everything but PBUF_ROM!). Cleaned up
+    pbuf.c: removed functions no needed any more (by etharp).
+
+  2007-04-11 Kieran Mansley
+  * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix
+    "Constant is long" warnings with 16bit compilers.  Contributed by
+    avatar@mmlab.cse.yzu.edu.tw
+
+  2007-04-05 Frédéric Bernon, Jonathan Larmour
+  * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on
+    the mailbox is active". Now, the post is only done during a connect, and do_send,
+    do_write and do_join_leave_group don't do anything if a previous error was signaled.
+
+  2007-04-03 Frédéric Bernon
+  * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output
+    packets. See patch #5834.
+
+  2007-03-30 Frédéric Bernon
+  * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add
+    missing  pcb allocations checking (in do_bind, and for each raw_new). Fix style.
+
+  2007-03-30 Frédéric Bernon
+  * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with
+    others environment defines (these were too "generic").
+
+  2007-03-28 Frédéric Bernon
+  * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call
+    result and can cause a crash. lwip_send now check netbuf_ref result.
+
+  2007-03-28 Simon Goldschmidt
+  * sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple
+    definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is
+    defined. This is the way it should have been already (looking at
+    doc/sys_arch.txt)
+
+  2007-03-28 Kieran Mansley
+  * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS +
+    IP and TCP headers *and* physical link headers
+
+  2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov)
+  * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
+    to send some garbage. It is not a definitive solution, but the patch does solve
+    the problem for most cases.
+
+  2007-03-22 Frédéric Bernon
+  * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).
+
+  2007-03-22 Frédéric Bernon
+  * api_lib.c: somes resources couldn't be freed if there was errors during
+    netconn_new_with_proto_and_callback.
+
+  2007-03-22 Frédéric Bernon
+  * ethernetif.c: update netif->input calls to check return value. In older ports,
+    it's a good idea to upgrade them, even if before, there could be another problem
+    (access to an uninitialized mailbox).
+
+  2007-03-21 Simon Goldschmidt
+  * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
+    by casting to unsigned).
+
+  2007-03-21 Frédéric Bernon
+  * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
+    api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
+    dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
+    Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
+    faster and more reliable communication between api_lib and tcpip.
+
+  2007-03-21 Frédéric Bernon
+  * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.
+
+  2007-03-21 Frédéric Bernon
+  * api_msg.c, igmp.c, igmp.h: Fix C++ style comments
+
+  2007-03-21 Kieran Mansley
+  * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
+    IP and TCP headers
+
+  2007-03-21 Kieran Mansley
+  * Fix all uses of pbuf_header to check the return value.  In some
+    cases just assert if it fails as I'm not sure how to fix them, but
+    this is no worse than before when they would carry on regardless
+    of the failure.
+
+  2007-03-21 Kieran Mansley
+  * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and
+    comment out missing header include in icmp.c
+
+  2007-03-20 Frédéric Bernon
+  * memp.h, stats.c: Fix stats_display function where memp_names table wasn't
+    synchronized with memp.h.
+
+  2007-03-20 Frédéric Bernon
+  * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input,
+    tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with 
+    network interfaces. Also fix a compiler warning.
+
+  2007-03-20 Kieran Mansley
+  * udp.c: Only try and use pbuf_header() to make space for headers if
+    not a ROM or REF pbuf.
+
+  2007-03-19 Frédéric Bernon
+  * api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
+    and api_msg_post().
+
+  2007-03-19 Frédéric Bernon
+  * Remove unimplemented "memp_realloc" function from memp.h.
+
+  2007-03-11 Simon Goldschmidt
+  * pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused
+    memory corruption.
+
+  2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov)
+  * api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251
+    (missing `const' qualifier in socket functions), to get more compatible to
+    standard POSIX sockets.
+
+  2007-03-11 Frédéric Bernon (based on patch from Dmitry Potapov)
+  * sockets.c: Add asserts inside bind, connect and sendto to check input
+    parameters. Remove excessive set_errno() calls after get_socket(), because
+    errno is set inside of get_socket(). Move last sock_set_errno() inside
+    lwip_close.
+
+  2007-03-09 Simon Goldschmidt
+  * memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory
+    was allocated too small.
+
+  2007-03-06 Simon Goldschmidt
+  * tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
+    the stack from concurrent access.
+
+  2007-03-06 Frédéric Bernon, Dmitry Potapov
+  * tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy
+    call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
+
+  2007-03-06 Simon Goldschmidt
+  * ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files
+    if IP_FRAG == 0 and IP_REASSEMBLY == 0
+
+  2007-03-06 Frédéric Bernon, Simon Goldschmidt
+  * opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
+    option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput.
+    Allow to do ARP processing for incoming packets inside tcpip_thread
+    (protecting ARP layer against concurrent access). You can also disable
+    old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.
+    Older ports have to use tcpip_ethinput.
+
+  2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov)
+  * err.h, err.c: fixed compiler warning "initialization dircards qualifiers
+    from pointer target type"
+
+  2007-03-05 Frédéric Bernon
+  * opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
+    ETHARP_TRUST_IP_MAC, review SO_REUSE)
+
+  2007-03-04 Frédéric Bernon
+  * api_msg.c: Remove some compiler warnings : parameter "pcb" was never
+    referenced.
+
+  2007-03-04 Frédéric Bernon
+  * api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
+    Dmitry Potapov).
+    The api_msg struct stay on the stack (not moved to netconn struct).
+
+  2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov)
+  * pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if
+    SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available)
+    Also fixed cast warning in pbuf_alloc()
+
+  2007-03-04 Simon Goldschmidt
+  * etharp.c, etharp.h, memp.c, memp.h, opt.h: Fix BUG#11400 - don't corrupt
+    existing pbuf chain when enqueuing multiple pbufs to a pending ARP request
+
+  2007-03-03 Frédéric Bernon
+  * udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
+    It is static, and never used in udp.c except udp_init().
+
+  2007-03-02 Simon Goldschmidt
+  * tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
+    tcpip_thread() to tcpip_init(). This way, raw API connections can be
+    initialized before tcpip_thread is running (e.g. before OS is started)
+
+  2007-03-02 Frédéric Bernon
+  * rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call
+    interval.
+
+  2007-02-28 Kieran Mansley 
+  * pbuf.c: Fix BUG#17645 - ensure pbuf payload pointer is not moved
+    outside the region of the pbuf by pbuf_header()
+
+  2007-02-28 Kieran Mansley 
+  * sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero
+    when supplied timeout is also non-zero 
+
+(STABLE-1.2.0)
+
+  2006-12-05 Leon Woestenberg
+  * CHANGELOG: Mention STABLE-1.2.0 release.
+
+  ++ New features:
+
+  2006-12-01 Christiaan Simons
+  * mem.h, opt.h: Added MEM_LIBC_MALLOC option.
+    Note this is a workaround. Currently I have no other options left.
+
+  2006-10-26 Christiaan Simons (accepted patch by Jonathan Larmour)
+  * ipv4/ip_frag.c: rename MAX_MTU to IP_FRAG_MAX_MTU and move define
+    to include/lwip/opt.h.
+  * ipv4/lwip/ip_frag.h: Remove unused IP_REASS_INTERVAL.
+    Move IP_REASS_MAXAGE and IP_REASS_BUFSIZE to include/lwip/opt.h.
+  * opt.h: Add above new options.
+
+  2006-08-18 Christiaan Simons
+  * tcp_{in,out}.c: added SNMP counters.
+  * ipv4/ip.c: added SNMP counters.
+  * ipv4/ip_frag.c: added SNMP counters.
+
+  2006-08-08 Christiaan Simons
+  * etharp.{c,h}: added etharp_find_addr() to read
+    (stable) ethernet/IP address pair from ARP table
+
+  2006-07-14 Christiaan Simons
+  * mib_structs.c: added
+  * include/lwip/snmp_structs.h: added
+  * netif.{c,h}, netif/ethernetif.c: added SNMP statistics to netif struct
+
+  2006-07-06 Christiaan Simons
+  * snmp/asn1_{enc,dec}.c added
+  * snmp/mib2.c added
+  * snmp/msg_{in,out}.c added
+  * include/lwip/snmp_asn1.h added
+  * include/lwip/snmp_msg.h added
+  * doc/snmp_agent.txt added
+
+  2006-03-29 Christiaan Simons
+  * inet.c, inet.h: Added platform byteswap support.
+    Added LWIP_PLATFORM_BYTESWAP define (defaults to 0) and
+    optional LWIP_PLATFORM_HTONS(), LWIP_PLATFORM_HTONL() macros.
+
+  ++ Bug fixes:
+
+  2006-11-30 Christiaan Simons
+  * dhcp.c: Fixed false triggers of request_timeout.
+
+  2006-11-28 Christiaan Simons
+  * netif.c: In netif_add() fixed missing clear of ip_addr, netmask, gw and flags.
+
+  2006-10-11 Christiaan Simons
+  * api_lib.c etharp.c, ip.c, memp.c, stats.c, sys.{c,h} tcp.h:
+    Partially accepted patch #5449 for ANSI C compatibility / build fixes.
+  * ipv4/lwip/ip.h ipv6/lwip/ip.h: Corrected UDP-Lite protocol
+    identifier from 170 to 136 (bug #17574).
+
+  2006-10-10 Christiaan Simons
+  * api_msg.c: Fixed Nagle algorithm as reported by Bob Grice.
+
+  2006-08-17 Christiaan Simons
+  * udp.c: Fixed bug #17200, added check for broadcast
+    destinations for PCBs bound to a unicast address.
+
+  2006-08-07 Christiaan Simons
+  * api_msg.c: Flushing TCP output in do_close() (bug #15926).
+
+  2006-06-27 Christiaan Simons
+  * api_msg.c: Applied patch for cold case (bug #11135).
+    In accept_function() ensure newconn->callback is always initialized.
+
+  2006-06-15 Christiaan Simons
+  * mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748),
+    facilitate printing of mem_size_t and u16_t statistics.
+
+  2006-06-14 Christiaan Simons
+  * api_msg.c: Applied patch #5146 to handle allocation failures
+    in accept() by Kevin Lawson.
+
+  2006-05-26 Christiaan Simons
+  * api_lib.c: Removed conn->sem creation and destruction 
+    from netconn_write() and added sys_sem_new to netconn_new_*.
+
+(STABLE-1_1_1)
+
+  2006-03-03  Christiaan Simons
+  * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
+    access and added pbuf_alloc() return value checks.
+
+  2006-01-01  Leon Woestenberg <leon.woestenberg@gmx.net>
+  * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
+    now handled by the checksum routine properly.
+
+  2006-02-27  Leon Woestenberg <leon.woestenberg@gmx.net>
+   * pbuf.c: Fix alignment; pbuf_init() would not work unless
+     pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
+
+  2005-12-20  Leon Woestenberg <leon.woestenberg@gmx.net>
+  * tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
+    submitted by Mitrani Hiroshi.
+
+  2005-12-15  Christiaan Simons
+  * inet.c: Disabled the added summing routine to preserve code space.
+
+  2005-12-14  Leon Woestenberg <leon.woestenberg@gmx.net>
+  * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
+    Added Curt McDowell's optimized checksumming routine for future
+    inclusion. Need to create test case for unaliged, aligned, odd,
+    even length combination of cases on various endianess machines.
+
+  2005-12-09  Christiaan Simons
+  * inet.c: Rewrote standard checksum routine in proper portable C.
+
+  2005-11-25  Christiaan Simons
+  * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
+  * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
+    u32_t, s32_t typedefs. This solves most debug word-length assumes.
+
+  2005-07-17 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * inet.c: Fixed unaligned 16-bit access in the standard checksum
+    routine by Peter Jolasson.
+  * slipif.c: Fixed implementation assumption of single-pbuf datagrams.
+
+  2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
+  * tcp_{out|in}.c: Applied patch fixing unaligned access.
+
+  2005-01-04 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
+
+  2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * udp.c: UDP pcb->recv() was called even when it was NULL.
+
+(STABLE-1_1_0)
+
+  2004-12-28 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * etharp.*: Disabled multiple packets on the ARP queue.
+    This clashes with TCP queueing.
+
+  2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * etharp.*: Fixed race condition from ARP request to ARP timeout.
+    Halved the ARP period, doubled the period counts.
+    ETHARP_MAX_PENDING now should be at least 2. This prevents
+    the counter from reaching 0 right away (which would allow
+    too little time for ARP responses to be received).
+
+  2004-11-25 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * dhcp.c: Decline messages were not multicast but unicast.
+  * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
+    Do not try hard to insert arbitrary packet's source address,
+    etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD. 
+    etharp_query() now always DOES call ETHARP_TRY_HARD so that users
+    querying an address will see it appear in the cache (DHCP could
+    suffer from this when a server invalidly gave an in-use address.)
+  * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
+    comparing network addresses (identifiers), not the network masks
+    themselves.
+  * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
+    IP address actually belongs to the network of the given interface.
+
+  2004-11-24 Kieran Mansley <kjm25@cam.ac.uk>
+  * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
+
+(STABLE-1_1_0-RC1)
+
+  2004-10-16 Kieran Mansley <kjm25@cam.ac.uk>
+  * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
+    even if one is already pending, if the rcv_wnd is above a threshold
+    (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
+    delayed ACK in order to open the window if the stack is only receiving data.
+
+  2004-09-12 Kieran Mansley <kjm25@cam.ac.uk>
+  * tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
+
+  2004-08-20 Tony Mountifield <tony@softins.co.uk>
+  * etharp.c: Make sure the first pbuf queued on an ARP entry
+    is properly ref counted.
+
+  2004-07-27 Tony Mountifield <tony@softins.co.uk>
+  * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
+    warnings about comparison.
+  * pbuf.c: Stopped compiler complaining of empty if statement
+    when LWIP_DEBUGF() empty.  Closed an unclosed comment.
+  * tcp.c: Stopped compiler complaining of empty if statement
+    when LWIP_DEBUGF() empty.
+  * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
+  * inet.c: Added a couple of casts to quiet the compiler.
+    No need to test isascii(c) before isdigit(c) or isxdigit(c).
+
+  2004-07-22 Tony Mountifield <tony@softins.co.uk>
+  * inet.c: Made data types consistent in inet_ntoa().
+    Added casts for return values of checksum routines, to pacify compiler.
+  * ip_frag.c, tcp_out.c, sockets.c, pbuf.c
+    Small corrections to some debugging statements, to pacify compiler.
+
+  2004-07-21 Tony Mountifield <tony@softins.co.uk>
+  * etharp.c: Removed spurious semicolon and added missing end-of-comment.
+  * ethernetif.c Updated low_level_output() to match prototype for
+    netif->linkoutput and changed low_level_input() similarly for consistency.
+  * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
+    of raw_recv() in raw.h and so avoid compiler error.
+  * sockets.c: Added trivial (int) cast to keep compiler happier.
+  * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
+
+(STABLE-1_0_0)
+
+  ++ Changes:
+
+  2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
+    your cc.h file defines this either 1 or 0. If non-defined,
+    defaults to 1.
+  * .c: Added <string.h> and <errno.h> includes where used.
+  * etharp.c: Made some array indices unsigned.
+
+  2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * netif.*: Added netif_set_up()/down().
+  * dhcp.c: Changes to restart program flow.
+
+  2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * etharp.c: In find_entry(), instead of a list traversal per candidate, do a
+    single-pass lookup for different candidates. Should exploit locality.
+
+  2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * tcp*.c: Cleaned up source comment documentation for Doxygen processing.
+  * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
+  * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
+    the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.
+
+  ++ Bug fixes:
+
+  2004-04-27 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
+    suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
+    non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
+    is to prefix the 14-bit Ethernet headers with two padding bytes.
+
+  2004-04-23 Leon Woestenberg <leon.woestenberg@gmx.net>
+  * ip_addr.c: Fix in the ip_addr_isbroadcast() check.
+  * etharp.c: Fixed the case where the packet that initiates the ARP request
+    is not queued, and gets lost. Fixed the case where the packets destination
+    address is already known; we now always queue the packet and perform an ARP
+    request.
+
+(STABLE-0_7_0)
+
+  ++ Bug fixes:
+
+  * Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
+  * Fixed TCP bug in dequeueing of FIN from out of order segment queue.
+  * Fixed two possible NULL references in rare cases.
+
+(STABLE-0_6_6)
+
+  ++ Bug fixes:
+
+  * Fixed DHCP which did not include the IP address in DECLINE messages.
+
+  ++ Changes:
+
+  * etharp.c has been hauled over a bit.
+
+(STABLE-0_6_5)
+
+  ++ Bug fixes:
+
+  * Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
+  * Packets sent from ARP queue had invalid source hardware address.
+
+  ++ Changes:
+
+  * Pass-by ARP requests do now update the cache.
+
+  ++ New features:
+
+  * No longer dependent on ctype.h.
+  * New socket options.
+  * Raw IP pcb support.
+
+(STABLE-0_6_4)
+
+  ++ Bug fixes:
+
+  * Some debug formatters and casts fixed.
+  * Numereous fixes in PPP.
+
+  ++ Changes:
+
+  * DEBUGF now is LWIP_DEBUGF
+  * pbuf_dechain() has been re-enabled.
+  * Mentioned the changed use of CVS branches in README.
+
+(STABLE-0_6_3)
+
+  ++ Bug fixes:
+
+  * Fixed pool pbuf memory leak in pbuf_alloc().
+    Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
+    Reported by Savin Zlobec.
+
+  * PBUF_POOL chains had their tot_len field not set for non-first
+    pbufs. Fixed in pbuf_alloc().
+
+  ++ New features:
+
+  * Added PPP stack contributed by Marc Boucher
+
+  ++ Changes:
+
+  * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
+
+  * ARP queueuing now queues the latest packet instead of the first.
+    This is the RFC recommended behaviour, but can be overridden in
+    lwipopts.h.
+
+(0.6.2)
+
+  ++ Bugfixes:
+
+  * TCP has been fixed to deal with the new use of the pbuf->ref
+    counter.
+
+  * DHCP dhcp_inform() crash bug fixed.
+
+  ++ Changes:
+
+  * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
+    pbuf_refresh(). This has sped up pbuf pool operations considerably.
+    Implemented by David Haas.
+
+(0.6.1)
+
+  ++ New features:
+
+  * The packet buffer implementation has been enhanced to support
+    zero-copy and copy-on-demand for packet buffers which have their
+    payloads in application-managed memory.
+    Implemented by David Haas.
+
+    Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
+    if an outgoing packet can be directly sent on the link, or perform
+    a copy-on-demand when necessary.
+
+    The application can safely assume the packet is sent, and the RAM
+    is available to the application directly after calling udp_send()
+    or similar function.
+
+  ++ Bugfixes:
+
+  * ARP_QUEUEING should now correctly work for all cases, including
+    PBUF_REF.
+    Implemented by Leon Woestenberg.
+
+  ++ Changes:
+
+  * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
+    to a '0.0.0.0' IP address.
+
+  * The packet buffer implementation is changed. The pbuf->ref counter
+    meaning has changed, and several pbuf functions have been
+    adapted accordingly.
+
+  * netif drivers have to be changed to set the hardware address length field
+    that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
+    See the contrib/ports/c16x cs8900 driver as a driver example.
+
+  * netif's have a dhcp field that must be initialized to NULL by the driver.
+    See the contrib/ports/c16x cs8900 driver as a driver example.
+
+(0.5.x) This file has been unmaintained up to 0.6.1. All changes are
+  logged in CVS but have not been explained here.
+
+(0.5.3) Changes since version 0.5.2
+
+  ++ Bugfixes:
+
+  * memp_malloc(MEMP_API_MSG) could fail with multiple application
+    threads because it wasn't protected by semaphores.
+
+  ++ Other changes:
+
+  * struct ip_addr now packed.
+
+  * The name of the time variable in arp.c has been changed to ctime
+    to avoid conflicts with the time() function.
+
+(0.5.2) Changes since version 0.5.1
+
+  ++ New features:
+
+  * A new TCP function, tcp_tmr(), now handles both TCP timers.
+
+  ++ Bugfixes:
+
+  * A bug in tcp_parseopt() could cause the stack to hang because of a
+    malformed TCP option.
+
+  * The address of new connections in the accept() function in the BSD
+    socket library was not handled correctly.
+
+  * pbuf_dechain() did not update the ->tot_len field of the tail.
+
+  * Aborted TCP connections were not handled correctly in all
+    situations.
+
+  ++ Other changes:
+
+  * All protocol header structs are now packed.
+
+  * The ->len field in the tcp_seg structure now counts the actual
+    amount of data, and does not add one for SYN and FIN segments.
+
+(0.5.1) Changes since version 0.5.0
+
+  ++ New features:
+
+  * Possible to run as a user process under Linux.
+
+  * Preliminary support for cross platform packed structs.
+
+  * ARP timer now implemented.
+
+  ++ Bugfixes:
+
+  * TCP output queue length was badly initialized when opening
+    connections.
+
+  * TCP delayed ACKs were not sent correctly.
+
+  * Explicit initialization of BSS segment variables.
+
+  * read() in BSD socket library could drop data.
+
+  * Problems with memory alignment.
+
+  * Situations when all TCP buffers were used could lead to
+    starvation.
+
+  * TCP MSS option wasn't parsed correctly.
+
+  * Problems with UDP checksum calculation.
+
+  * IP multicast address tests had endianess problems.
+
+  * ARP requests had wrong destination hardware address.
+
+  ++ Other changes:
+
+  * struct eth_addr changed from u16_t[3] array to u8_t[6].
+
+  * A ->linkoutput() member was added to struct netif.
+
+  * TCP and UDP ->dest_* struct members where changed to ->remote_*.
+
+  * ntoh* macros are now null definitions for big endian CPUs.
+
+(0.5.0) Changes since version 0.4.2
+
+  ++ New features:
+
+  * Redesigned operating system emulation layer to make porting easier.
+
+  * Better control over TCP output buffers.
+
+  * Documenation added.
+
+  ++ Bugfixes:
+
+  * Locking issues in buffer management.
+
+  * Bugfixes in the sequential API.
+
+  * IP forwarding could cause memory leakage. This has been fixed.
+
+  ++ Other changes:
+
+  * Directory structure somewhat changed; the core/ tree has been
+    collapsed.
+
+(0.4.2) Changes since version 0.4.1
+
+  ++ New features:
+
+  * Experimental ARP implementation added.
+
+  * Skeleton Ethernet driver added.
+
+  * Experimental BSD socket API library added.
+
+  ++ Bugfixes:
+
+  * In very intense situations, memory leakage could occur. This has
+    been fixed.
+
+  ++ Other changes:
+
+  * Variables named "data" and "code" have been renamed in order to
+    avoid name conflicts in certain compilers.
+
+  * Variable++ have in appliciable cases been translated to ++variable
+    since some compilers generate better code in the latter case.
+
+(0.4.1) Changes since version 0.4
+
+  ++ New features:
+
+  * TCP: Connection attempts time out earlier than data
+    transmissions. Nagle algorithm implemented. Push flag set on the
+    last segment in a burst.
+
+  * UDP: experimental support for UDP-Lite extensions.
+
+  ++ Bugfixes:
+
+  * TCP: out of order segments were in some cases handled incorrectly,
+    and this has now been fixed. Delayed acknowledgements was broken
+    in 0.4, has now been fixed. Binding to an address that is in use
+    now results in an error. Reset connections sometimes hung an
+    application; this has been fixed.
+
+  * Checksum calculation sometimes failed for chained pbufs with odd
+    lengths. This has been fixed.
+
+  * API: a lot of bug fixes in the API. The UDP API has been improved
+    and tested. Error reporting and handling has been
+    improved. Logical flaws and race conditions for incoming TCP
+    connections has been found and removed.
+
+  * Memory manager: alignment issues. Reallocating memory sometimes
+    failed, this has been fixed.
+
+  * Generic library: bcopy was flawed and has been fixed.
+
+  ++ Other changes:
+
+  * API: all datatypes has been changed from generic ones such as
+    ints, to specified ones such as u16_t. Functions that return
+    errors now have the correct type (err_t).
+
+  * General: A lot of code cleaned up and debugging code removed. Many
+    portability issues have been fixed.
+
+  * The license was changed; the advertising clause was removed.
+
+  * C64 port added.
+
+  * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
+    Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
+    fixing bugs!
+
+(0.4) Changes since version 0.3.1
+
+  * Memory management has been radically changed; instead of
+    allocating memory from a shared heap, memory for objects that are
+    rapidly allocated and deallocated is now kept in pools. Allocation
+    and deallocation from those memory pools is very fast. The shared
+    heap is still present but is used less frequently.
+
+  * The memory, memory pool, and packet buffer subsystems now support
+    4-, 2-, or 1-byte alignment.
+
+  * "Out of memory" situations are handled in a more robust way.
+
+  * Stack usage has been reduced.
+
+  * Easier configuration of lwIP parameters such as memory usage,
+    TTLs, statistics gathering, etc. All configuration parameters are
+    now kept in a single header file "lwipopts.h".
+
+  * The directory structure has been changed slightly so that all
+    architecture specific files are kept under the src/arch
+    hierarchy.
+
+  * Error propagation has been improved, both in the protocol modules
+    and in the API.
+
+  * The code for the RTXC architecture has been implemented, tested
+    and put to use.
+
+  * Bugs have been found and corrected in the TCP, UDP, IP, API, and
+    the Internet checksum modules.
+
+  * Bugs related to porting between a 32-bit and a 16-bit architecture
+    have been found and corrected.
+
+  * The license has been changed slightly to conform more with the
+    original BSD license, including the advertisement clause.
+
+(0.3.1) Changes since version 0.3
+
+  * Fix of a fatal bug in the buffer management. Pbufs with allocated
+    RAM never returned the RAM when the pbuf was deallocated.
+
+  * TCP congestion control, window updates and retransmissions did not
+    work correctly. This has now been fixed.
+
+  * Bugfixes in the API.
+
+(0.3) Changes since version 0.2
+
+  * New and improved directory structure. All include files are now
+    kept in a dedicated include/ directory.
+
+  * The API now has proper error handling. A new function,
+    netconn_err(), now returns an error code for the connection in
+    case of errors.
+
+  * Improvements in the memory management subsystem. The system now
+    keeps a pointer to the lowest free memory block. A new function,
+    mem_malloc2() tries to allocate memory once, and if it fails tries
+    to free some memory and retry the allocation.
+
+  * Much testing has been done with limited memory
+    configurations. lwIP now does a better job when overloaded.
+
+  * Some bugfixes and improvements to the buffer (pbuf) subsystem.
+
+  * Many bugfixes in the TCP code:
+
+    - Fixed a bug in tcp_close().
+
+    - The TCP receive window was incorrectly closed when out of
+      sequence segments was received. This has been fixed.
+
+    - Connections are now timed-out of the FIN-WAIT-2 state.
+
+    - The initial congestion window could in some cases be too
+      large. This has been fixed.
+
+    - The retransmission queue could in some cases be screwed up. This
+      has been fixed.
+
+    - TCP RST flag now handled correctly.
+
+    - Out of sequence data was in some cases never delivered to the
+      application. This has been fixed.
+
+    - Retransmitted segments now contain the correct acknowledgment
+      number and advertised window.
+
+    - TCP retransmission timeout backoffs are not correctly computed
+      (ala BSD). After a number of retransmissions, TCP now gives up
+      the connection.
+
+  * TCP connections now are kept on three lists, one for active
+    connections, one for listening connections, and one for
+    connections that are in TIME-WAIT. This greatly speeds up the fast
+    timeout processing for sending delayed ACKs.
+
+  * TCP now provides proper feedback to the application when a
+    connection has been successfully set up.
+
+  * More comments have been added to the code. The code has also been
+    somewhat cleaned up.
+
+(0.2) Initial public release.

+INTRODUCTION
+
+lwIP is a small independent implementation of the TCP/IP protocol
+suite that has been developed by Adam Dunkels at the Computer and
+Networks Architectures (CNA) lab at the Swedish Institute of Computer
+Science (SICS).
+
+The focus of the lwIP TCP/IP implementation is to reduce the RAM usage
+while still having a full scale TCP. This making lwIP suitable for use
+in embedded systems with tens of kilobytes of free RAM and room for
+around 40 kilobytes of code ROM.
+
+
+FEATURES
+
+  * IP (Internet Protocol, IPv4 and IPv6) including packet forwarding over
+    multiple network interfaces
+  * ICMP (Internet Control Message Protocol) for network maintenance and debugging
+  * IGMP (Internet Group Management Protocol) for multicast traffic management
+  * MLD (Multicast listener discovery for IPv6). Aims to be compliant with 
+    RFC 2710. No support for MLDv2
+  * ND (Neighbor discovery and stateless address autoconfiguration for IPv6).
+    Aims to be compliant with RFC 4861 (Neighbor discovery) and RFC 4862
+    (Address autoconfiguration)
+  * UDP (User Datagram Protocol) including experimental UDP-lite extensions
+  * TCP (Transmission Control Protocol) with congestion control, RTT estimation
+    and fast recovery/fast retransmit
+  * raw/native API for enhanced performance
+  * Optional Berkeley-like socket API
+  * DNS (Domain names resolver)
+
+
+APPLICATIONS
+
+  * HTTP server with SSI and CGI
+  * SNMPv2c agent with MIB compiler (Simple Network Management Protocol)
+  * SNTP (Simple network time protocol)
+  * NetBIOS name service responder
+  * MDNS (Multicast DNS) responder
+  * iPerf server implementation

+
+
+DEVELOPMENT
+
+lwIP has grown into an excellent TCP/IP stack for embedded devices,
+and developers using the stack often submit bug fixes, improvements,
+and additions to the stack to further increase its usefulness.
+
+Development of lwIP is hosted on Savannah, a central point for
+software development, maintenance and distribution. Everyone can
+help improve lwIP by use of Savannah's interface, Git and the
+mailing list. A core team of developers will commit changes to the
+Git source tree.
+
+The lwIP TCP/IP stack is maintained in the 'lwip' Git module and
+contributions (such as platform ports) are in the 'contrib' Git module.
+
+See doc/savannah.txt for details on Git server access for users and
+developers.
+
+The current Git trees are web-browsable:
+  http://git.savannah.gnu.org/cgit/lwip.git
+  http://git.savannah.gnu.org/cgit/lwip/lwip-contrib.git
+
+Submit patches and bugs via the lwIP project page:
+  http://savannah.nongnu.org/projects/lwip/
+
+Continuous integration builds (GCC, clang):
+  https://travis-ci.org/yarrick/lwip-merged
+
+
+DOCUMENTATION
+
+Self documentation of the source code is regularly extracted from the current
+Git sources and is available from this web page:
+  http://www.nongnu.org/lwip/
+
+There is now a constantly growing wiki about lwIP at
+  http://lwip.wikia.com/wiki/LwIP_Wiki
+
+Also, there are mailing lists you can subscribe at
+  http://savannah.nongnu.org/mail/?group=lwip
+plus searchable archives:
+  http://lists.nongnu.org/archive/html/lwip-users/
+  http://lists.nongnu.org/archive/html/lwip-devel/
+
+lwIP was originally written by Adam Dunkels:
+  http://dunkels.com/adam/
+
+Reading Adam's papers, the files in docs/, browsing the source code
+documentation and browsing the mailing list archives is a good way to
+become familiar with the design of lwIP.

+This file lists major changes between release versions that require
+ports or applications to be changed. Use it to update a port or an
+application written for an older version of lwIP to correctly work
+with newer versions.
+
+
+(git master)
+
+  * [Enter new changes just after this line - do not remove this line]
+
+(2.0.1)
+
+  ++ Application changes:
+
+  * UDP does NOT receive multicast traffic from ALL netifs on an UDP PCB bound to a specific
+    netif any more. Users need to bind to IP_ADDR_ANY to receive multicast traffic and compare 
+    ip_current_netif() to the desired netif for every packet.
+    See bug #49662 for an explanation.
+
+(2.0.0)
+
+  ++ Application changes:
+
+  * Changed netif "up" flag handling to be an administrative flag (as opposed to the previous meaning of
+    "ip4-address-valid", a netif will now not be used for transmission if not up) -> even a DHCP netif
+    has to be set "up" before starting the DHCP client
+  * Added IPv6 support (dual-stack or IPv4/IPv6 only)
+  * Changed ip_addr_t to be a union in dual-stack mode (use ip4_addr_t where referring to IPv4 only).
+  * Major rewrite of SNMP (added MIB parser that creates code stubs for custom MIBs);
+    supports SNMPv2c (experimental v3 support)
+  * Moved some core applications from contrib repository to src/apps (and include/lwip/apps)
+
+  +++ Raw API:
+    * Changed TCP listen backlog: removed tcp_accepted(), added the function pair tcp_backlog_delayed()/
+      tcp_backlog_accepted() to explicitly delay backlog handling on a connection pcb
+
+  +++ Socket API:
+    * Added an implementation for posix sendmsg()
+    * Added LWIP_FIONREAD_LINUXMODE that makes ioctl/FIONREAD return the size of the next pending datagram
+
+  ++ Port changes
+
+  +++ new files:
+    * MANY new and moved files! 
+    * Added src/Filelists.mk for use in Makefile projects
+    * Continued moving stack-internal parts from abc.h to abc_priv.h in sub-folder "priv"
+      to let abc.h only contain the actual application programmer's API
+
+  +++ sys layer:
+    * Made LWIP_TCPIP_CORE_LOCKING==1 the default as it usually performs better than
+      the traditional message passing (although with LWIP_COMPAT_MUTEX you are still
+      open to priority inversion, so this is not recommended any more)
+    * Added LWIP_NETCONN_SEM_PER_THREAD to use one "op_completed" semaphore per thread
+      instead of using one per netconn (these semaphores are used even with core locking
+      enabled as some longer lasting functions like big writes still need to delay)
+    * Added generalized abstraction for itoa(), strnicmp(), stricmp() and strnstr()
+      in def.h (to be overridden in cc.h) instead of config 
+      options for netbiosns, httpd, dns, etc. ...
+    * New abstraction for hton* and ntoh* functions in def.h.
+      To override them, use the following in cc.h: 
+      #define lwip_htons(x) <your_htons>
+      #define lwip_htonl(x) <your_htonl>
+
+  +++ new options:
+     * TODO
+
+  +++ new pools:
+     * Added LWIP_MEMPOOL_* (declare/init/alloc/free) to declare private memp pools
+       that share memp.c code but do not have to be made global via lwippools.h
+     * Added pools for IPv6, MPU_COMPATIBLE, dns-api, netif-api, etc.
+     * added hook LWIP_HOOK_MEMP_AVAILABLE() to get informed when a memp pool was empty and an item
+       is now available
+
+  * Signature of LWIP_HOOK_VLAN_SET macro was changed
+
+  * LWIP_DECLARE_MEMORY_ALIGNED() may be used to declare aligned memory buffers (mem/memp)
+    or to move buffers to dedicated memory using compiler attributes
+
+  * Standard C headers are used to define sized types and printf formatters
+    (disable by setting LWIP_NO_STDINT_H=1 or LWIP_NO_INTTYPES_H=1 if your compiler
+    does not support these)
+
+
+  ++ Major bugfixes/improvements
+
+  * Added IPv6 support (dual-stack or IPv4/IPv6 only)
+  * Major rewrite of PPP (incl. keep-up with apache pppd)
+    see doc/ppp.txt for an upgrading how-to
+  * Major rewrite of SNMP (incl. MIB parser)
+  * Fixed timing issues that might have lead to losing a DHCP lease
+  * Made rx processing path more robust against crafted errors
+  * TCP window scaling support
+  * modification of api modules to support FreeRTOS-MPU (don't pass stack-pointers to other threads)
+  * made DNS client more robust
+  * support PBUF_REF for RX packets
+  * LWIP_NETCONN_FULLDUPLEX allows netconn/sockets to be used for reading/writing from separate
+    threads each (needs LWIP_NETCONN_SEM_PER_THREAD)
+  * Moved and reordered stats (mainly memp/mib2)
+
+(1.4.0)
+
+  ++ Application changes:
+
+  * Replaced struct ip_addr by typedef ip_addr_t (struct ip_addr is kept for
+    compatibility to old applications, but will be removed in the future).
+
+  * Renamed mem_realloc() to mem_trim() to prevent confusion with realloc()
+
+  +++ Raw API:
+    * Changed the semantics of tcp_close() (since it was rather a
+      shutdown before): Now the application does *NOT* get any calls to the recv
+      callback (aside from NULL/closed) after calling tcp_close()
+
+    * When calling tcp_abort() from a raw API TCP callback function,
+      make sure you return ERR_ABRT to prevent accessing unallocated memory.
+      (ERR_ABRT now means the applicaiton has called tcp_abort!)
+
+  +++ Netconn API:
+    * Changed netconn_receive() and netconn_accept() to return
+      err_t, not a pointer to new data/netconn.
+
+  +++ Socket API:
+    * LWIP_SO_RCVTIMEO: when accept() or recv() time out, they
+      now set errno to EWOULDBLOCK/EAGAIN, not ETIMEDOUT.
+
+    * Added a minimal version of posix fctl() to have a
+      standardised way to set O_NONBLOCK for nonblocking sockets.
+
+  +++ all APIs:
+    * correctly implemented SO(F)_REUSEADDR
+
+  ++ Port changes
+
+  +++ new files:
+
+    * Added 4 new files: def.c, timers.c, timers.h, tcp_impl.h:
+
+    * Moved stack-internal parts of tcp.h to tcp_impl.h, tcp.h now only contains
+      the actual application programmer's API
+  
+    * Separated timer implementation from sys.h/.c, moved to timers.h/.c;
+      Added timer implementation for NO_SYS==1, set NO_SYS_NO_TIMERS==1 if you
+      still want to use your own timer implementation for NO_SYS==0 (as before).
+
+  +++ sys layer:
+
+    * Converted mbox- and semaphore-functions to take pointers to sys_mbox_t/
+      sys_sem_t;
+
+    * Converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
+
+    * Added Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX to let sys.h use
+      binary semaphores instead of mutexes - as before)
+
+  +++ new options:
+
+     * Don't waste memory when chaining segments, added option TCP_OVERSIZE to
+       prevent creating many small pbufs when calling tcp_write with many small
+       blocks of data. Instead, pbufs are allocated larger than needed and the
+       space is used for later calls to tcp_write.
+
+     * Added LWIP_NETIF_TX_SINGLE_PBUF to always copy to try to create single pbufs
+       in tcp_write/udp_send.
+
+    * Added an additional option LWIP_ETHERNET to support ethernet without ARP
+      (necessary for pure PPPoE)
+
+    * Add MEMP_SEPARATE_POOLS to place memory pools in separate arrays. This may
+      be used to place these pools into user-defined memory by using external
+      declaration.
+
+    * Added TCP_SNDQUEUELOWAT corresponding to TCP_SNDLOWAT
+
+  +++ new pools:
+
+     * Netdb uses a memp pool for allocating memory when getaddrinfo() is called,
+       so MEMP_NUM_NETDB has to be set accordingly.
+
+     * DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses a memp pool instead of the heap, so
+       MEMP_NUM_LOCALHOSTLIST has to be set accordingly.
+
+     * Snmp-agent uses a memp pools instead of the heap, so MEMP_NUM_SNMP_* have
+       to be set accordingly.
+
+     * PPPoE uses a MEMP pool instead of the heap, so MEMP_NUM_PPPOE_INTERFACES
+       has to be set accordingly
+
+  * Integrated loopif into netif.c - loopif does not have to be created by the
+    port any more, just define LWIP_HAVE_LOOPIF to 1.
+
+  * Added define LWIP_RAND() for lwip-wide randomization (needs to be defined
+    in cc.h, e.g. used by igmp)
+
+  * Added printf-formatter X8_F to printf u8_t as hex
+
+  * The heap now may be moved to user-defined memory by defining
+    LWIP_RAM_HEAP_POINTER as a void pointer to that memory's address
+
+  * added autoip_set_struct() and dhcp_set_struct() to let autoip and dhcp work
+    with user-allocated structs instead of calling mem_malloc
+
+  * Added const char* name to mem- and memp-stats for easier debugging.
+
+  * Calculate the TCP/UDP checksum while copying to only fetch data once:
+    Define LWIP_CHKSUM_COPY to a memcpy-like function that returns the checksum
+
+  * Added SO_REUSE_RXTOALL to pass received UDP broadcast/multicast packets to
+    more than one pcb.
+
+  * Changed the semantics of ARP_QUEUEING==0: ARP_QUEUEING now cannot be turned
+    off any more, if this is set to 0, only one packet (the most recent one) is
+    queued (like demanded by RFC 1122).
+
+  
+  ++ Major bugfixes/improvements
+
+  * Implemented tcp_shutdown() to only shut down one end of a connection
+  * Implemented shutdown() at socket- and netconn-level
+  * Added errorset support to select() + improved select speed overhead
+  * Merged pppd to v2.3.11 (including some backported bugfixes from 2.4.x)
+  * Added timer implementation for NO_SYS==1 (may be disabled with NO_SYS_NO_TIMERS==1
+  * Use macros defined in ip_addr.h to work with IP addresses
+  * Implemented many nonblocking socket/netconn functions
+  * Fixed ARP input processing: only add a new entry if a request was directed as us
+  * mem_realloc() to mem_trim() to prevent confusion with realloc()
+  * Some improvements for AutoIP (don't route/forward link-local addresses, don't break
+    existing connections when assigning a routable address)
+  * Correctly handle remote side overrunning our rcv_wnd in ooseq case
+  * Removed packing from ip_addr_t, the packed version is now only used in protocol headers
+  * Corrected PBUF_POOL_BUFSIZE for ports where ETH_PAD_SIZE > 0
+  * Added support for static ARP table entries
+

+1 Introduction
+
+This document describes some guidelines for people participating
+in lwIP development.
+
+2 How to contribute to lwIP
+
+Here is a short list of suggestions to anybody working with lwIP and 
+trying to contribute bug reports, fixes, enhancements, platform ports etc.
+First of all as you may already know lwIP is a volunteer project so feedback
+to fixes or questions might often come late. Hopefully the bug and patch tracking 
+features of Savannah help us not lose users' input.
+
+2.1 Source code style:
+
+1. do not use tabs.
+2. indentation is two spaces per level (i.e. per tab).
+3. end debug messages with a trailing newline (\n).
+4. one space between keyword and opening bracket.
+5. no space between function and opening bracket.
+6. one space and no newline before opening curly braces of a block.
+7. closing curly brace on a single line.
+8. spaces surrounding assignment and comparisons.
+9. don't initialize static and/or global variables to zero, the compiler takes care of that.
+10. use current source code style as further reference.
+
+2.2 Source code documentation style:
+
+1. JavaDoc compliant and Doxygen compatible.
+2. Function documentation above functions in .c files, not .h files.
+   (This forces you to synchronize documentation and implementation.)
+3. Use current documentation style as further reference.
+ 
+2.3 Bug reports and patches:
+
+1. Make sure you are reporting bugs or send patches against the latest
+   sources. (From the latest release and/or the current Git sources.)
+2. If you think you found a bug make sure it's not already filed in the
+   bugtracker at Savannah.
+3. If you have a fix put the patch on Savannah. If it is a patch that affects
+   both core and arch specific stuff please separate them so that the core can
+   be applied separately while leaving the other patch 'open'. The preferred way
+   is to NOT touch archs you can't test and let maintainers take care of them.
+   This is a good way to see if they are used at all - the same goes for unix
+   netifs except tapif.
+4. Do not file a bug and post a fix to it to the patch area. Either a bug report
+   or a patch will be enough.
+   If you correct an existing bug then attach the patch to the bug rather than creating a new entry in the patch area.
+5. Patches should be specific to a single change or to related changes. Do not mix bugfixes with spelling and other
+   trivial fixes unless the bugfix is trivial too. Do not reorganize code and rename identifiers in the same patch you
+   change behaviour if not necessary. A patch is easier to read and understand if it's to the point and short than
+   if it's not to the point and long :) so the chances for it to be applied are greater. 
+
+2.4 Platform porters:
+
+1. If you have ported lwIP to a platform (an OS, a uC/processor or a combination of these) and
+   you think it could benefit others[1] you might want discuss this on the mailing list. You
+   can also ask for Git access to submit and maintain your port in the contrib Git module.

+/**
+ * @page pitfalls Common pitfalls
+ *
+ * Multiple Execution Contexts in lwIP code
+ * ========================================
+ *
+ * The most common source of lwIP problems is to have multiple execution contexts
+ * inside the lwIP code.
+ * 
+ * lwIP can be used in two basic modes: @ref lwip_nosys (no OS/RTOS 
+ * running on target system) or @ref lwip_os (there is an OS running
+ * on the target system).
+ *
+ * Mainloop Mode
+ * -------------
+ * In mainloop mode, only @ref callbackstyle_api can be used.
+ * The user has two possibilities to ensure there is only one 
+ * exection context at a time in lwIP:
+ *
+ * 1) Deliver RX ethernet packets directly in interrupt context to lwIP
+ *    by calling netif->input directly in interrupt. This implies all lwIP 
+ *    callback functions are called in IRQ context, which may cause further
+ *    problems in application code: IRQ is blocked for a long time, multiple
+ *    execution contexts in application code etc. When the application wants
+ *    to call lwIP, it only needs to disable interrupts during the call.
+ *    If timers are involved, even more locking code is needed to lock out
+ *    timer IRQ and ethernet IRQ from each other, assuming these may be nested.
+ *
+ * 2) Run lwIP in a mainloop. There is example code here: @ref lwip_nosys.
+ *    lwIP is _ONLY_ called from mainloop callstacks here. The ethernet IRQ
+ *    has to put received telegrams into a queue which is polled in the
+ *    mainloop. Ensure lwIP is _NEVER_ called from an interrupt, e.g.
+ *    some SPI IRQ wants to forward data to udp_send() or tcp_write()!
+ *
+ * OS Mode
+ * -------
+ * In OS mode, @ref callbackstyle_api AND @ref sequential_api can be used.
+ * @ref sequential_api are designed to be called from threads other than
+ * the TCPIP thread, so there is nothing to consider here.
+ * But @ref callbackstyle_api functions must _ONLY_ be called from
+ * TCPIP thread. It is a common error to call these from other threads
+ * or from IRQ contexts. ​Ethernet RX needs to deliver incoming packets
+ * in the correct way by sending a message to TCPIP thread, this is
+ * implemented in tcpip_input().​​
+ * Again, ensure lwIP is _NEVER_ called from an interrupt, e.g.
+ * some SPI IRQ wants to forward data to udp_send() or tcp_write()!
+ * 
+ * 1) tcpip_callback() can be used get called back from TCPIP thread,
+ *    it is safe to call any @ref callbackstyle_api from there.
+ *
+ * 2) Use @ref LWIP_TCPIP_CORE_LOCKING. All @ref callbackstyle_api
+ *    functions can be called when lwIP core lock is aquired, see
+ *    @ref LOCK_TCPIP_CORE() and @ref UNLOCK_TCPIP_CORE().
+ *    These macros cannot be used in an interrupt context!
+ *    Note the OS must correctly handle priority inversion for this.

+Multicast DNS for lwIP
+
+Author: Erik Ekman
+
+
+Note! The MDNS responder does not have all features required by the standards.
+See notes in src/apps/mdns/mdns.c for what is left. It is however usable in normal
+cases - but watch out if many devices on the same network try to use the same
+host/service instance names.
+
+
+How to enable:
+==============
+
+MDNS support does not depend on DNS.
+MDNS supports using IPv4 only, v6 only, or v4+v6.
+
+To enable MDNS responder, set
+  LWIP_MDNS_RESPONDER = 1
+in lwipopts.h and add src/apps/mdns/mdns.c to your list of files to build.
+
+The max number of services supported per netif is defined by MDNS_MAX_SERVICES,
+default is 1.
+
+Increase MEMP_NUM_UDP_PCB by 1. MDNS needs one PCB.
+Increase LWIP_NUM_NETIF_CLIENT_DATA by 1 (MDNS needs one entry on netif).
+
+MDNS with IPv4 requires LWIP_IGMP = 1, and preferably LWIP_AUTOIP = 1.
+MDNS with IPv6 requires LWIP_IPV6_MLD = 1, and that a link-local address is
+generated.
+
+The MDNS code puts its structs on the stack where suitable to reduce dynamic
+memory allocation. It may use up to 1kB of stack.
+
+MDNS needs a strncasecmp() implementation. If you have one, define
+LWIP_MDNS_STRNCASECMP to it. Otherwise the code will provide an implementation
+for you.
+
+
+How to use:
+===========
+
+Call mdns_resp_init() during system initialization.
+This opens UDP sockets on port 5353 for IPv4 and IPv6.
+
+
+To start responding on a netif, run
+  mdns_resp_add_netif(struct netif *netif, char *hostname, u32_t dns_ttl)
+
+The hostname will be copied. If this returns successfully, the netif will join
+the multicast groups and any MDNS/legacy DNS requests sent unicast or multicast
+to port 5353 will be handled:
+- <hostname>.local type A, AAAA or ANY returns relevant IP addresses
+- Reverse lookups (PTR in-addr.arpa, ip6.arpa) of netif addresses
+  returns <hostname>.local
+Answers will use the supplied TTL (in seconds)
+MDNS allows UTF-8 names, but it is recommended to stay within ASCII,
+since the default case-insensitive comparison assumes this.
+
+It is recommended to call this function after an IPv4 address has been set,
+since there is currently no check if the v4 address is valid.
+
+Call mdns_resp_netif_settings_changed() every time the IP address
+on the netif has changed.
+
+To stop responding on a netif, run
+  mdns_resp_remove_netif(struct netif *netif)
+
+
+Adding services:
+================
+
+The netif first needs to be registered. Then run
+  mdns_resp_add_service(struct netif *netif, char *name, char *service,
+      u16_t proto, u16_t port, u32_t dns_ttl,
+      service_get_txt_fn_t txt_fn, void *txt_userdata);
+
+The name and service pointers will be copied. Name refers to the name of the
+service instance, and service is the type of service, like _http
+proto can be DNSSD_PROTO_UDP or DNSSD_PROTO_TCP which represent _udp and _tcp.
+If this call returns successfully, the following queries will be answered:
+- _services._dns-sd._udp.local type PTR returns <service>.<proto>.local
+- <service>.<proto>.local type PTR returns <name>.<service>.<proto>.local
+- <name>.<service>.<proto>.local type SRV returns hostname and port of service
+- <name>.<service>.<proto>.local type TXT builds text strings by calling txt_fn
+  with the supplied userdata. The callback adds strings to the reply by calling
+  mdns_resp_add_service_txtitem(struct mdns_service *service, char *txt,
+   int txt_len). Example callback method:
+
+   static void srv_txt(struct mdns_service *service, void *txt_userdata)
+   {
+     res = mdns_resp_add_service_txtitem(service, "path=/", 6);
+     LWIP_ERROR("mdns add service txt failed\n", (res == ERR_OK), return);
+   }
+
+  Since a hostname struct is used for TXT storage each single item can be max
+  63 bytes long, and  the total max length (including length bytes for each
+  item) is 255 bytes.
+
+If your device runs a webserver on port 80, an example call might be:
+
+  mdns_resp_add_service(netif, "myweb", "_http"
+      DNSSD_PROTO_TCP, 80, 3600, srv_txt, NULL);
+
+which will publish myweb._http._tcp.local for any hosts looking for web servers,
+and point them to <hostname>.local:80
+
+Relevant information will be sent as additional records to reduce number of
+requests required from a client.
+
+Removing services is currently not supported. Services are removed when the
+netif is removed.

+MQTT client for lwIP
+
+Author: Erik Andersson

+
+-----------------------------------------------------------------
+1. Initial steps, reserve memory and make connection to server:
+
+1.1: Provide storage
+
+Static allocation:
+  mqtt_client_t static_client;
+  example_do_connect(&static_client);
+
+Dynamic allocation:
+  mqtt_client_t *client = mqtt_client_new();
+  if(client != NULL) {
+    example_do_connect(&client);
+  }
+  
+1.2: Establish Connection with server
+
+void example_do_connect(mqtt_client_t *client)
+{
+  struct mqtt_connect_client_info_t ci;
+  err_t err;
+  
+  /* Setup an empty client info structure */
+  memset(&ci, 0, sizeof(ci));
+  
+  /* Minimal amount of information required is client identifier, so set it here */ 
+  ci.client_id = "lwip_test";
+  
+  /* Initiate client and connect to server, if this fails immediately an error code is returned
+     otherwise mqtt_connection_cb will be called with connection result after attempting 
+     to establish a connection with the server. 
+     For now MQTT version 3.1.1 is always used */

+  err = mqtt_client_connect(client, ip_addr, MQTT_PORT, mqtt_connection_cb, 0, &ci);
+  
+  /* For now just print the result code if something goes wrong
+  if(err != ERR_OK) {
+    printf("mqtt_connect return %d\n", err);
+  }
+}
+
+Connection to server can also be probed by calling mqtt_client_is_connected(client) 
+
+-----------------------------------------------------------------
+2. Implementing the connection status callback
+
+
+static void mqtt_connection_cb(mqtt_client_t *client, void *arg, mqtt_connection_status_t status)
+{
+  err_t err;
+  if(status == MQTT_CONNECT_ACCEPTED) {

+     notifying user, retry subscribe or disconnect from server */
+  printf("Subscribe result: %d\n", result);
+}

+3. Implementing callbacks for incoming publish and data
+
+/* The idea is to demultiplex topic and create some reference to be used in data callbacks
+   Example here uses a global variable, better would be to use a member in arg
+   If RAM and CPU budget allows it, the easiest implementation might be to just take a copy of

+  } else if(topic[0] == 'A') {

+    inpub_id = 1;
+  } else {
+    /* For all other topics */
+    inpub_id = 2;
+  }
+}
+
+static void mqtt_incoming_data_cb(void *arg, const u8_t *data, u16_t len, u8_t flags)
+{
+  printf("Incoming publish payload with length %d, flags %u\n", len, (unsigned int)flags);
+
+  if(flags & MQTT_DATA_FLAG_LAST) {
+    /* Last fragment of payload received (or whole part if payload fits receive buffer

+

+4. Using outgoing publish
+
+
+void example_publish(mqtt_client_t *client, void *arg)
+{
+  const char *pub_payload= "PubSubHubLubJub";
+  err_t err;
+  u8_t qos = 2; /* 0 1 or 2, see MQTT specification */
+  u8_t retain = 0; /* No don't retain such crappy payload... */
+  err = mqtt_publish(client, "pub_topic", pub_payload, strlen(pub_payload), qos, retain, mqtt_pub_request_cb, arg);
+  if(err != ERR_OK) {
+    printf("Publish err: %d\n", err);
+  }
+}
+
+/* Called when publish is complete either with sucess or failure */
+static void mqtt_pub_request_cb(void *arg, err_t result)
+{
+  if(result != ERR_OK) {
+    printf("Publish result: %d\n", result);
+  }
+}
+
+-----------------------------------------------------------------
+5. Disconnecting
+
+Simply call mqtt_disconnect(client)

+ */
+ppp_free(ppp);
+
+
+
+3 PPPoS input path (raw API, IRQ safe API, TCPIP API)
+=====================================================
+
+Received data on serial port should be sent to lwIP using the pppos_input()
+function or the pppos_input_tcpip() function.
+
+If NO_SYS is 1 and if PPP_INPROC_IRQ_SAFE is 0 (the default), pppos_input()
+is not IRQ safe and then *MUST* only be called inside your main loop.
+
+Whatever the NO_SYS value, if PPP_INPROC_IRQ_SAFE is 1, pppos_input() is IRQ
+safe and can be safely called from an interrupt context, using that is going
+to reduce your need of buffer if pppos_input() is called byte after byte in
+your rx serial interrupt.
+
+if NO_SYS is 0, the thread safe way outside an interrupt context is to use
+the pppos_input_tcpip() function to pass input data to the lwIP core thread
+using the TCPIP API. This is thread safe in all cases but you should avoid
+passing data byte after byte because it uses heavy locking (mailbox) and it
+allocates pbuf, better fill them !
+
+if NO_SYS is 0 and if PPP_INPROC_IRQ_SAFE is 1, you may also use pppos_input()
+from an RX thread, however pppos_input() is not thread safe by itself. You can
+do that *BUT* you should NEVER call pppos_connect(), pppos_listen() and
+ppp_free() if pppos_input() can still be running, doing this is NOT thread safe
+at all. Using PPP_INPROC_IRQ_SAFE from an RX thread is discouraged unless you
+really know what you are doing, your move ;-)
+
+
+/*
+ * Fonction to call for received data
+ *
+ * ppp, PPP control block
+ * buffer, input buffer
+ * buffer_len, buffer length in bytes
+ */
+void pppos_input(ppp, buffer, buffer_len);
+
+or
+
+void pppos_input_tcpip(ppp, buffer, buffer_len);
+
+
+
+4 Thread safe PPP API (PPPAPI)
+==============================
+
+There is a thread safe API for all corresponding ppp_* functions, you have to
+enable LWIP_PPP_API in your lwipopts.h file, then see
+include/netif/ppp/pppapi.h, this is actually pretty obvious.
+
+
+
+5 Notify phase callback (PPP_NOTIFY_PHASE)
+==========================================
+
+Notify phase callback, enabled using the PPP_NOTIFY_PHASE config option, let
+you configure a callback that is called on each PPP internal state change.
+This is different from the status callback which only warns you about
+up(running) and down(dead) events.
+
+Notify phase callback can be used, for example, to set a LED pattern depending
+on the current phase of the PPP session. Here is a callback example which
+tries to mimic what we usually see on xDSL modems while they are negotiating
+the link, which should be self-explanatory:
+
+static void ppp_notify_phase_cb(ppp_pcb *pcb, u8_t phase, void *ctx) {
+  switch (phase) {
+
+  /* Session is down (either permanently or briefly) */
+  case PPP_PHASE_DEAD:
+    led_set(PPP_LED, LED_OFF);
+    break;
+
+  /* We are between two sessions */
+  case PPP_PHASE_HOLDOFF:
+    led_set(PPP_LED, LED_SLOW_BLINK);
+    break;
+
+  /* Session just started */
+  case PPP_PHASE_INITIALIZE:
+    led_set(PPP_LED, LED_FAST_BLINK);
+    break;
+
+  /* Session is running */
+  case PPP_PHASE_RUNNING:
+    led_set(PPP_LED, LED_ON);
+    break;
+
+  default:
+    break;
+  }
+}
+
+
+
+6 Upgrading from lwIP <= 1.4.x to lwIP >= 2.0.x
+===============================================
+
+PPP API was fully reworked between 1.4.x and 2.0.x releases. However porting
+from previous lwIP version is pretty easy:
+
+* Previous PPP API used an integer to identify PPP sessions, we are now
+  using ppp_pcb* control block, therefore all functions changed from "int ppp"
+  to "ppp_pcb *ppp"
+
+* struct netif was moved outside the PPP structure, you have to provide a netif
+  for PPP interface in pppoX_create() functions
+
+* PPP session are not started automatically after you created them anymore,
+  you have to call ppp_connect(), this way you can configure the session before
+  starting it.
+
+* Previous PPP API used CamelCase, we are now using snake_case.
+
+* Previous PPP API mixed PPPoS and PPPoE calls, this isn't the case anymore,
+  PPPoS functions are now prefixed pppos_ and PPPoE functions are now prefixed
+  pppoe_, common functions are now prefixed ppp_.
+
+* New PPPERR_ error codes added, check you have all of them in your status
+  callback function
+
+* Only the following include files should now be used in user application:
+  #include "netif/ppp/pppapi.h"
+  #include "netif/ppp/pppos.h"
+  #include "netif/ppp/pppoe.h"
+  #include "netif/ppp/pppol2tp.h"
+
+  Functions from ppp.h can be used, but you don't need to include this header
+  file as it is already included by above header files.
+
+* PPP_INPROC_OWNTHREAD was broken by design and was removed, you have to create
+  your own serial rx thread
+
+* PPP_INPROC_MULTITHREADED option was misnamed and confusing and was renamed
+  PPP_INPROC_IRQ_SAFE, please read the "PPPoS input path" documentation above
+  because you might have been fooled by that
+
+* If you used tcpip_callback_with_block() on ppp_ functions you may wish to use
+  the PPPAPI API instead.
+
+* ppp_sighup and ppp_close functions were merged using an optional argument
+  "nocarrier" on ppp_close.
+
+* DNS servers are now only remotely asked if LWIP_DNS is set and if
+  ppp_set_usepeerdns() is set to true, they are now automatically registered
+  using the dns_setserver() function so you don't need to do that in the PPP
+  callback anymore.
+
+* PPPoS does not use the SIO API anymore, as such it now requires a serial
+  output callback in place of sio_write
+
+* PPP_MAXIDLEFLAG is now in ms instead of jiffies

+Raw TCP/IP interface for lwIP
+
+Authors: Adam Dunkels, Leon Woestenberg, Christiaan Simons
+
+lwIP provides three Application Program's Interfaces (APIs) for programs
+to use for communication with the TCP/IP code:
+* low-level "core" / "callback" or "raw" API.
+* higher-level "sequential" API.
+* BSD-style socket API.
+
+The raw API (sometimes called native API) is an event-driven API designed
+to be used without an operating system that implements zero-copy send and
+receive. This API is also used by the core stack for interaction between
+the various protocols. It is the only API available when running lwIP
+without an operating system.
+
+The sequential API provides a way for ordinary, sequential, programs
+to use the lwIP stack. It is quite similar to the BSD socket API. The
+model of execution is based on the blocking open-read-write-close
+paradigm. Since the TCP/IP stack is event based by nature, the TCP/IP
+code and the application program must reside in different execution
+contexts (threads).
+
+The socket API is a compatibility API for existing applications,
+currently it is built on top of the sequential API. It is meant to
+provide all functions needed to run socket API applications running
+on other platforms (e.g. unix / windows etc.). However, due to limitations
+in the specification of this API, there might be incompatibilities
+that require small modifications of existing programs.
+
+** Multithreading
+
+lwIP started targeting single-threaded environments. When adding multi-
+threading support, instead of making the core thread-safe, another
+approach was chosen: there is one main thread running the lwIP core
+(also known as the "tcpip_thread"). When running in a multithreaded
+environment, raw API functions MUST only be called from the core thread
+since raw API functions are not protected from concurrent access (aside
+from pbuf- and memory management functions). Application threads using
+the sequential- or socket API communicate with this main thread through
+message passing.
+
+      As such, the list of functions that may be called from
+      other threads or an ISR is very limited! Only functions
+      from these API header files are thread-safe:
+      - api.h
+      - netbuf.h
+      - netdb.h
+      - netifapi.h
+      - pppapi.h
+      - sockets.h
+      - sys.h
+
+      Additionaly, memory (de-)allocation functions may be
+      called from multiple threads (not ISR!) with NO_SYS=0
+      since they are protected by SYS_LIGHTWEIGHT_PROT and/or
+      semaphores.
+
+      Netconn or Socket API functions are thread safe against the
+      core thread but they are not reentrant at the control block
+      granularity level. That is, a UDP or TCP control block must
+      not be shared among multiple threads without proper locking.
+
+      If SYS_LIGHTWEIGHT_PROT is set to 1 and
+      LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT is set to 1,
+      pbuf_free() may also be called from another thread or
+      an ISR (since only then, mem_free - for PBUF_RAM - may
+      be called from an ISR: otherwise, the HEAP is only
+      protected by semaphores).
+
+
+** The remainder of this document discusses the "raw" API. **
+
+The raw TCP/IP interface allows the application program to integrate
+better with the TCP/IP code. Program execution is event based by
+having callback functions being called from within the TCP/IP
+code. The TCP/IP code and the application program both run in the same
+thread. The sequential API has a much higher overhead and is not very
+well suited for small systems since it forces a multithreaded paradigm
+on the application.
+
+The raw TCP/IP interface is not only faster in terms of code execution
+time but is also less memory intensive. The drawback is that program
+development is somewhat harder and application programs written for
+the raw TCP/IP interface are more difficult to understand. Still, this
+is the preferred way of writing applications that should be small in
+code size and memory usage.
+
+All APIs can be used simultaneously by different application
+programs. In fact, the sequential API is implemented as an application
+program using the raw TCP/IP interface.
+
+Do not confuse the lwIP raw API with raw Ethernet or IP sockets.
+The former is a way of interfacing the lwIP network stack (including
+TCP and UDP), the later refers to processing raw Ethernet or IP data
+instead of TCP connections or UDP packets.
+
+Raw API applications may never block since all packet processing
+(input and output) as well as timer processing (TCP mainly) is done
+in a single execution context.
+
+--- Callbacks
+
+Program execution is driven by callbacks functions, which are then
+invoked by the lwIP core when activity related to that application
+occurs. A particular application may register to be notified via a
+callback function for events such as incoming data available, outgoing
+data sent, error notifications, poll timer expiration, connection
+closed, etc. An application can provide a callback function to perform
+processing for any or all of these events. Each callback is an ordinary
+C function that is called from within the TCP/IP code. Every callback
+function is passed the current TCP or UDP connection state as an
+argument. Also, in order to be able to keep program specific state,
+the callback functions are called with a program specified argument
+that is independent of the TCP/IP state.
+
+The function for setting the application connection state is:
+
+- void tcp_arg(struct tcp_pcb *pcb, void *arg)
+
+  Specifies the program specific state that should be passed to all
+  other callback functions. The "pcb" argument is the current TCP
+  connection control block, and the "arg" argument is the argument
+  that will be passed to the callbacks.
+
+  
+--- TCP connection setup
+
+The functions used for setting up connections is similar to that of
+the sequential API and of the BSD socket API. A new TCP connection
+identifier (i.e., a protocol control block - PCB) is created with the
+tcp_new() function. This PCB can then be either set to listen for new
+incoming connections or be explicitly connected to another host.
+
+- struct tcp_pcb *tcp_new(void)
+
+  Creates a new connection identifier (PCB). If memory is not
+  available for creating the new pcb, NULL is returned.
+
+- err_t tcp_bind(struct tcp_pcb *pcb, ip_addr_t *ipaddr,
+                 u16_t port)
+
+  Binds the pcb to a local IP address and port number. The IP address
+  can be specified as IP_ADDR_ANY in order to bind the connection to
+  all local IP addresses.
+
+  If another connection is bound to the same port, the function will
+  return ERR_USE, otherwise ERR_OK is returned.
+
+- struct tcp_pcb *tcp_listen(struct tcp_pcb *pcb)
+
+  Commands a pcb to start listening for incoming connections. When an
+  incoming connection is accepted, the function specified with the
+  tcp_accept() function will be called. The pcb will have to be bound
+  to a local port with the tcp_bind() function.
+
+  The tcp_listen() function returns a new connection identifier, and
+  the one passed as an argument to the function will be
+  deallocated. The reason for this behavior is that less memory is
+  needed for a connection that is listening, so tcp_listen() will
+  reclaim the memory needed for the original connection and allocate a
+  new smaller memory block for the listening connection.
+
+  tcp_listen() may return NULL if no memory was available for the
+  listening connection. If so, the memory associated with the pcb
+  passed as an argument to tcp_listen() will not be deallocated.
+
+- struct tcp_pcb *tcp_listen_with_backlog(struct tcp_pcb *pcb, u8_t backlog)
+
+  Same as tcp_listen, but limits the number of outstanding connections
+  in the listen queue to the value specified by the backlog argument.
+  To use it, your need to set TCP_LISTEN_BACKLOG=1 in your lwipopts.h.
+
+- void tcp_accept(struct tcp_pcb *pcb,
+                  err_t (* accept)(void *arg, struct tcp_pcb *newpcb,
+                                   err_t err))
+
+  Specified the callback function that should be called when a new
+  connection arrives on a listening connection.
+
+- err_t tcp_connect(struct tcp_pcb *pcb, ip_addr_t *ipaddr,
+                    u16_t port, err_t (* connected)(void *arg,
+                                                    struct tcp_pcb *tpcb,
+                                                    err_t err));
+
+  Sets up the pcb to connect to the remote host and sends the
+  initial SYN segment which opens the connection. 
+
+  The tcp_connect() function returns immediately; it does not wait for
+  the connection to be properly setup. Instead, it will call the
+  function specified as the fourth argument (the "connected" argument)
+  when the connection is established. If the connection could not be
+  properly established, either because the other host refused the
+  connection or because the other host didn't answer, the "err"
+  callback function of this pcb (registered with tcp_err, see below)
+  will be called.
+
+  The tcp_connect() function can return ERR_MEM if no memory is
+  available for enqueueing the SYN segment. If the SYN indeed was
+  enqueued successfully, the tcp_connect() function returns ERR_OK.
+
+
+--- Sending TCP data
+
+TCP data is sent by enqueueing the data with a call to
+tcp_write(). When the data is successfully transmitted to the remote
+host, the application will be notified with a call to a specified
+callback function.
+
+- err_t tcp_write(struct tcp_pcb *pcb, const void *dataptr, u16_t len,
+                  u8_t apiflags)
+
+  Enqueues the data pointed to by the argument dataptr. The length of
+  the data is passed as the len parameter. The apiflags can be one or more of:
+  - TCP_WRITE_FLAG_COPY: indicates whether the new memory should be allocated
+    for the data to be copied into. If this flag is not given, no new memory
+    should be allocated and the data should only be referenced by pointer. This
+    also means that the memory behind dataptr must not change until the data is
+    ACKed by the remote host
+  - TCP_WRITE_FLAG_MORE: indicates that more data follows. If this is omitted,
+    the PSH flag is set in the last segment created by this call to tcp_write.
+    If this flag is given, the PSH flag is not set.
+
+  The tcp_write() function will fail and return ERR_MEM if the length
+  of the data exceeds the current send buffer size or if the length of
+  the queue of outgoing segment is larger than the upper limit defined
+  in lwipopts.h. The number of bytes available in the output queue can
+  be retrieved with the tcp_sndbuf() function.
+
+  The proper way to use this function is to call the function with at
+  most tcp_sndbuf() bytes of data. If the function returns ERR_MEM,
+  the application should wait until some of the currently enqueued
+  data has been successfully received by the other host and try again.
+
+- void tcp_sent(struct tcp_pcb *pcb,
+                err_t (* sent)(void *arg, struct tcp_pcb *tpcb,
+                u16_t len))
+
+  Specifies the callback function that should be called when data has
+  successfully been received (i.e., acknowledged) by the remote
+  host. The len argument passed to the callback function gives the
+  amount bytes that was acknowledged by the last acknowledgment.
+
+  
+--- Receiving TCP data
+
+TCP data reception is callback based - an application specified
+callback function is called when new data arrives. When the
+application has taken the data, it has to call the tcp_recved()
+function to indicate that TCP can advertise increase the receive
+window.
+
+- void tcp_recv(struct tcp_pcb *pcb,
+                err_t (* recv)(void *arg, struct tcp_pcb *tpcb,
+                               struct pbuf *p, err_t err))
+
+  Sets the callback function that will be called when new data
+  arrives. The callback function will be passed a NULL pbuf to
+  indicate that the remote host has closed the connection. If
+  there are no errors and the callback function is to return
+  ERR_OK, then it must free the pbuf. Otherwise, it must not
+  free the pbuf so that lwIP core code can store it.
+
+- void tcp_recved(struct tcp_pcb *pcb, u16_t len)
+
+  Must be called when the application has received the data. The len
+  argument indicates the length of the received data.
+
+
+--- Application polling
+
+When a connection is idle (i.e., no data is either transmitted or
+received), lwIP will repeatedly poll the application by calling a
+specified callback function. This can be used either as a watchdog
+timer for killing connections that have stayed idle for too long, or
+as a method of waiting for memory to become available. For instance,
+if a call to tcp_write() has failed because memory wasn't available,
+the application may use the polling functionality to call tcp_write()
+again when the connection has been idle for a while.
+
+- void tcp_poll(struct tcp_pcb *pcb, 
+                err_t (* poll)(void *arg, struct tcp_pcb *tpcb),
+                u8_t interval)
+
+  Specifies the polling interval and the callback function that should
+  be called to poll the application. The interval is specified in
+  number of TCP coarse grained timer shots, which typically occurs
+  twice a second. An interval of 10 means that the application would
+  be polled every 5 seconds.
+
+
+--- Closing and aborting connections
+
+- err_t tcp_close(struct tcp_pcb *pcb)
+
+  Closes the connection. The function may return ERR_MEM if no memory
+  was available for closing the connection. If so, the application
+  should wait and try again either by using the acknowledgment
+  callback or the polling functionality. If the close succeeds, the
+  function returns ERR_OK.
+
+  The pcb is deallocated by the TCP code after a call to tcp_close(). 
+
+- void tcp_abort(struct tcp_pcb *pcb)
+
+  Aborts the connection by sending a RST (reset) segment to the remote
+  host. The pcb is deallocated. This function never fails.
+
+  ATTENTION: When calling this from one of the TCP callbacks, make
+  sure you always return ERR_ABRT (and never return ERR_ABRT otherwise
+  or you will risk accessing deallocated memory or memory leaks!
+
+
+If a connection is aborted because of an error, the application is
+alerted of this event by the err callback. Errors that might abort a
+connection are when there is a shortage of memory. The callback
+function to be called is set using the tcp_err() function.
+
+- void tcp_err(struct tcp_pcb *pcb, void (* err)(void *arg,
+       err_t err))
+
+  The error callback function does not get the pcb passed to it as a
+  parameter since the pcb may already have been deallocated.
+
+
+--- UDP interface
+
+The UDP interface is similar to that of TCP, but due to the lower
+level of complexity of UDP, the interface is significantly simpler.
+
+- struct udp_pcb *udp_new(void)
+
+  Creates a new UDP pcb which can be used for UDP communication. The
+  pcb is not active until it has either been bound to a local address
+  or connected to a remote address.
+
+- void udp_remove(struct udp_pcb *pcb)
+
+  Removes and deallocates the pcb.  
+  
+- err_t udp_bind(struct udp_pcb *pcb, ip_addr_t *ipaddr,
+                 u16_t port)
+
+  Binds the pcb to a local address. The IP-address argument "ipaddr"
+  can be IP_ADDR_ANY to indicate that it should listen to any local IP
+  address. The function currently always return ERR_OK.
+
+- err_t udp_connect(struct udp_pcb *pcb, ip_addr_t *ipaddr,
+                    u16_t port)
+
+  Sets the remote end of the pcb. This function does not generate any
+  network traffic, but only set the remote address of the pcb.
+
+- err_t udp_disconnect(struct udp_pcb *pcb)
+
+  Remove the remote end of the pcb. This function does not generate
+  any network traffic, but only removes the remote address of the pcb.
+
+- err_t udp_send(struct udp_pcb *pcb, struct pbuf *p)
+
+  Sends the pbuf p. The pbuf is not deallocated.
+
+- void udp_recv(struct udp_pcb *pcb,
+                void (* recv)(void *arg, struct udp_pcb *upcb,
+                                         struct pbuf *p,
+                                         ip_addr_t *addr,
+                                         u16_t port),
+                              void *recv_arg)
+
+  Specifies a callback function that should be called when a UDP
+  datagram is received.
+  
+
+--- System initalization
+
+A truly complete and generic sequence for initializing the lwIP stack
+cannot be given because it depends on additional initializations for
+your runtime environment (e.g. timers).
+
+We can give you some idea on how to proceed when using the raw API.
+We assume a configuration using a single Ethernet netif and the
+UDP and TCP transport layers, IPv4 and the DHCP client.
+
+Call these functions in the order of appearance:
+
+- lwip_init()
+
+  Initialize the lwIP stack and all of its subsystems.
+
+- netif_add(struct netif *netif, const ip4_addr_t *ipaddr,
+            const ip4_addr_t *netmask, const ip4_addr_t *gw,
+            void *state, netif_init_fn init, netif_input_fn input)
+
+  Adds your network interface to the netif_list. Allocate a struct
+  netif and pass a pointer to this structure as the first argument.
+  Give pointers to cleared ip_addr structures when using DHCP,
+  or fill them with sane numbers otherwise. The state pointer may be NULL.
+
+  The init function pointer must point to a initialization function for
+  your Ethernet netif interface. The following code illustrates its use.
+  
+  err_t netif_if_init(struct netif *netif)
+  {
+    u8_t i;
+    
+    for (i = 0; i < ETHARP_HWADDR_LEN; i++) {
+      netif->hwaddr[i] = some_eth_addr[i];
+    }
+    init_my_eth_device();
+    return ERR_OK;
+  }
+  
+  For Ethernet drivers, the input function pointer must point to the lwIP
+  function ethernet_input() declared in "netif/etharp.h". Other drivers
+  must use ip_input() declared in "lwip/ip.h".
+  
+- netif_set_default(struct netif *netif)
+
+  Registers the default network interface.
+
+- netif_set_link_up(struct netif *netif)
+
+  This is the hardware link state; e.g. whether cable is plugged for wired
+  Ethernet interface. This function must be called even if you don't know
+  the current state. Having link up and link down events is optional but
+  DHCP and IPv6 discover benefit well from those events.
+
+- netif_set_up(struct netif *netif)
+
+  This is the administrative (= software) state of the netif, when the
+  netif is fully configured this function must be called.
+
+- dhcp_start(struct netif *netif)
+
+  Creates a new DHCP client for this interface on the first call.
+  
+  You can peek in the netif->dhcp struct for the actual DHCP status.
+
+- sys_check_timeouts()
+
+  When the system is running, you have to periodically call
+  sys_check_timeouts() which will handle all timers for all protocols in
+  the stack; add this to your main loop or equivalent.
+
+
+--- Optimalization hints
+
+The first thing you want to optimize is the lwip_standard_checksum()
+routine from src/core/inet.c. You can override this standard
+function with the #define LWIP_CHKSUM <your_checksum_routine>.
+
+There are C examples given in inet.c or you might want to
+craft an assembly function for this. RFC1071 is a good
+introduction to this subject.
+
+Other significant improvements can be made by supplying
+assembly or inline replacements for htons() and htonl()
+if you're using a little-endian architecture.
+#define lwip_htons(x) <your_htons>
+#define lwip_htonl(x) <your_htonl>
+If you #define them to htons() and htonl(), you should
+#define LWIP_DONT_PROVIDE_BYTEORDER_FUNCTIONS to prevent lwIP from
+defining hton*/ntoh* compatibility macros.
+
+Check your network interface driver if it reads at
+a higher speed than the maximum wire-speed. If the
+hardware isn't serviced frequently and fast enough
+buffer overflows are likely to occur.
+
+E.g. when using the cs8900 driver, call cs8900if_service(ethif)
+as frequently as possible. When using an RTOS let the cs8900 interrupt
+wake a high priority task that services your driver using a binary
+semaphore or event flag. Some drivers might allow additional tuning
+to match your application and network.
+
+For a production release it is recommended to set LWIP_STATS to 0.
+Note that speed performance isn't influenced much by simply setting
+high values to the memory options.
+
+For more optimization hints take a look at the lwIP wiki.
+
+--- Zero-copy MACs
+
+To achieve zero-copy on transmit, the data passed to the raw API must
+remain unchanged until sent. Because the send- (or write-)functions return
+when the packets have been enqueued for sending, data must be kept stable
+after that, too.
+
+This implies that PBUF_RAM/PBUF_POOL pbufs passed to raw-API send functions
+must *not* be reused by the application unless their ref-count is 1.
+
+For no-copy pbufs (PBUF_ROM/PBUF_REF), data must be kept unchanged, too,
+but the stack/driver will/must copy PBUF_REF'ed data when enqueueing, while
+PBUF_ROM-pbufs are just enqueued (as ROM-data is expected to never change).
+
+Also, data passed to tcp_write without the copy-flag must not be changed!
+
+Therefore, be careful which type of PBUF you use and if you copy TCP data
+or not!

+Daily Use Guide for using Savannah for lwIP
+
+Table of Contents:
+
+1 - Obtaining lwIP from the Git repository
+2 - Committers/developers Git access using SSH
+3 - Merging a development branch to master branch
+4 - How to release lwIP
+
+
+
+1 Obtaining lwIP from the Git repository
+----------------------------------------
+
+To perform an anonymous Git clone of the master branch (this is where
+bug fixes and incremental enhancements occur), do this:
+ git clone git://git.savannah.nongnu.org/lwip.git
+
+Or, obtain a stable branch (updated with bug fixes only) as follows:
+ git clone --branch DEVEL-1_4_1 git://git.savannah.nongnu.org/lwip.git
+
+Or, obtain a specific (fixed) release as follows:
+ git clone --branch STABLE-1_4_1 git://git.savannah.nongnu.org/lwip.git
+
+
+2 Committers/developers Git access using SSH
+--------------------------------------------
+
+The Savannah server uses SSH (Secure Shell) protocol 2 authentication and encryption.
+As such, Git commits to the server occur through a SSH tunnel for project members.
+To create a SSH2 key pair in UNIX-like environments, do this:
+ ssh-keygen -t dsa
+
+Under Windows, a recommended SSH client is "PuTTY", freely available with good
+documentation and a graphic user interface. Use its key generator.
+
+Now paste the id_dsa.pub contents into your Savannah account public key list. Wait
+a while so that Savannah can update its configuration (This can take minutes).
+
+Try to login using SSH:
+ ssh -v your_login@git.sv.gnu.org
+
+If it tells you:
+ Linux vcs.savannah.gnu.org 2.6.32-5-xen-686 #1 SMP Wed Jun 17 17:10:03 UTC 2015 i686
+
+ Interactive shell login is not possible for security reasons.
+ VCS commands are allowed.
+ Last login: Tue May 15 23:10:12 2012 from 82.245.102.129
+ You tried to execute:
+ Sorry, you are not allowed to execute that command.
+ Shared connection to git.sv.gnu.org closed.
+
+then you could login; Savannah refuses to give you a shell - which is OK, as we
+are allowed to use SSH for Git only. Now, you should be able to do this:
+ git clone your_login@git.sv.gnu.org:/srv/git/lwip.git
+
+After which you can edit your local files with bug fixes or new features and
+commit them. Make sure you know what you are doing when using Git to make
+changes on the repository. If in doubt, ask on the lwip-members mailing list.
+
+(If SSH asks about authenticity of the host, you can check the key
+fingerprint against https://savannah.nongnu.org/git/?group=lwip
+
+
+3 - Merging a development branch to master branch
+-------------------------------------------------
+
+Merging is a straightforward process in Git. How to merge all changes in a
+development branch since our last merge from main:
+
+Checkout the master branch:
+ git checkout master
+
+Merge the development branch to master:
+ git merge your-development-branch
+
+Resolve any conflict.
+
+Commit the merge result.
+ git commit -a
+
+Push your commits:
+ git push
+
+
+4 How to release lwIP
+---------------------
+
+First, tag the release using Git: (I use release number 1.4.1 throughout
+this example).
+ git tag -a STABLE-1_4_1
+
+Share the tag reference by pushing it to remote:
+ git push origin STABLE-1_4_1
+
+Prepare the release:
+ cp -r lwip lwip-1.4.1
+ rm -rf lwip-1.4.1/.git lwip-1.4.1/.gitattributes
+
+Archive the current directory using tar, gzip'd, bzip2'd and zip'd.
+ tar czvf lwip-1.4.1.tar.gz lwip-1.4.1
+ tar cjvf lwip-1.4.1.tar.bz2 lwip-1.4.1
+ zip -r lwip-1.4.1.zip lwip-1.4.1
+
+Now, sign the archives with a detached GPG binary signature as follows:
+ gpg -b lwip-1.4.1.tar.gz
+ gpg -b lwip-1.4.1.tar.bz2
+ gpg -b lwip-1.4.1.zip
+
+Upload these files using anonymous FTP:
+ ncftp ftp://savannah.gnu.org/incoming/savannah/lwip
+ ncftp> mput *1.4.1.*
+
+Additionally, you may post a news item on Savannah, like this:
+
+A new 1.4.1 release is now available here:
+http://savannah.nongnu.org/files/?group=lwip&highlight=1.4.1
+
+You will have to submit this via the user News interface, then approve
+this via the Administrator News interface.

+SNMPv1 agent for lwIP
+
+Author: Christiaan Simons
+
+This is a brief introduction how to use and configure the SNMP agent.
+Note the agent uses the raw-API UDP interface so you may also want to
+read rawapi.txt to gain a better understanding of the SNMP message handling.
+
+0 Agent Capabilities
+====================
+
+SNMPv1 per RFC1157
+  This is an old(er) standard but is still widely supported.
+  For SNMPv2c and v3 have a greater complexity and need many
+  more lines of code. IMHO this breaks the idea of "lightweight IP".
+
+  Note the S in SNMP stands for "Simple". Note that "Simple" is
+  relative. SNMP is simple compared to the complex ISO network
+  management protocols CMIP (Common Management Information Protocol)
+  and CMOT (CMip Over Tcp).
+
+MIB II per RFC1213
+  The standard lwIP stack management information base.
+  This is a required MIB, so this is always enabled.
+  When builing lwIP without TCP, the mib-2.tcp group is omitted.
+  The groups EGP, CMOT and transmission are disabled by default.
+  
+  Most mib-2 objects are not writable except:
+  sysName, sysLocation, sysContact, snmpEnableAuthenTraps.
+  Writing to or changing the ARP and IP address and route
+  tables is not possible.
+ 
+  Note lwIP has a very limited notion of IP routing. It currently
+  doen't have a route table and doesn't have a notion of the U,G,H flags.
+  Instead lwIP uses the interface list with only one default interface
+  acting as a single gateway interface (G) for the default route.
+
+  The agent returns a "virtual table" with the default route 0.0.0.0
+  for the default interface and network routes (no H) for each
+  network interface in the netif_list.
+  All routes are considered to be up (U).
+
+Loading additional MIBs
+  MIBs can only be added in compile-time, not in run-time.
+  There is no MIB compiler thus additional MIBs must be hand coded.
+
+Large SNMP message support
+  The packet decoding and encoding routines are designed
+  to use pbuf-chains. Larger payloads than the minimum
+  SNMP requirement of 484 octets are supported if the 
+  PBUF_POOL_SIZE and IP_REASS_BUFSIZE are set to match your
+  local requirement.
+
+1 Building the Agent
+====================
+
+First of all you'll need to add the following define
+to your local lwipopts.h:
+
+#define LWIP_SNMP               1
+
+and add the source files in lwip/src/core/snmp
+and some snmp headers in lwip/src/include/lwip to your makefile.
+
+Note you'll might need to adapt you network driver to update
+the mib2 variables for your interface.
+
+2 Running the Agent
+===================
+
+The following function calls must be made in your program to
+actually get the SNMP agent running.
+
+Before starting the agent you should supply pointers
+to non-volatile memory for sysContact, sysLocation,
+and snmpEnableAuthenTraps. You can do this by calling
+
+snmp_set_syscontact()
+snmp_set_syslocation()
+snmp_set_snmpenableauthentraps()
+
+Additionally you may want to set
+
+snmp_set_sysdescr()
+snmp_set_sysobjid() (if you have a private MIB)
+snmp_set_sysname()
+
+Also before starting the agent you need to setup
+one or more trap destinations using these calls:
+
+snmp_trap_dst_enable();
+snmp_trap_dst_ip_set();
+
+In the lwIP initialisation sequence call snmp_init() just after
+the call to udp_init().
+
+Exactly every 10 msec the SNMP uptime timestamp must be updated with
+snmp_inc_sysuptime(). You should call this from a timer interrupt
+or a timer signal handler depending on your runtime environment.
+
+An alternative way to update the SNMP uptime timestamp is to do a call like
+snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but call to
+a lower frequency). Another one is to not call snmp_inc_sysuptime() or
+snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
+This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
+snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
+when it's queried (any function which need "sysuptime" have to call
+snmp_get_sysuptime).
+
+
+3 Private MIBs
+==============
+
+If want to extend the agent with your own private MIB you'll need to
+add the following define to your local lwipopts.h:
+
+#define SNMP_PRIVATE_MIB        1
+
+You must provide the private_mib.h and associated files yourself.
+Note we don't have a "MIB compiler" that generates C source from a MIB,
+so you're required to do some serious coding if you enable this!
+
+Note the lwIP enterprise ID (26381) is assigned to the lwIP project,
+ALL OBJECT IDENTIFIERS LIVING UNDER THIS ID ARE ASSIGNED BY THE lwIP
+MAINTAINERS!
+
+If you need to create your own private MIB you'll need
+to apply for your own enterprise ID with IANA: http://www.iana.org/numbers.html 
+
+You can set it by passing a struct snmp_obj_id to the agent
+using snmp_set_sysobjid(&my_object_id), just before snmp_init().
+
+Note the object identifiers for thes MIB-2 and your private MIB
+tree must be kept in sorted ascending (lexicographical) order.
+This to ensure correct getnext operation.
+
+An example for a private MIB is part of the "minimal Unix" project:
+contrib/ports/unix/proj/minimal/lwip_prvmib.c
+
+The next chapter gives a more detailed description of the
+MIB-2 tree and the optional private MIB.
+
+4 The Gory Details
+==================
+
+4.0 Object identifiers and the MIB tree.
+
+We have three distinct parts for all object identifiers:
+
+The prefix
+  .iso.org.dod.internet
+
+the middle part 
+  .mgmt.mib-2.ip.ipNetToMediaTable.ipNetToMediaEntry.ipNetToMediaPhysAddress
+
+and the index part
+  .1.192.168.0.1
+
+Objects located above the .internet hierarchy aren't supported.
+Currently only the .mgmt sub-tree is available and
+when the SNMP_PRIVATE_MIB is enabled the .private tree
+becomes available too.
+
+Object identifiers from incoming requests are checked
+for a matching prefix, middle part and index part
+or are expanded(*) for GetNext requests with short
+or inexisting names in the request.
+(* we call this "expansion" but this also
+resembles the "auto-completion" operation)
+
+The middle part is usually located in ROM (const)
+to preserve precious RAM on small microcontrollers.
+However RAM location is possible for a dynamically
+changing private tree.
+
+The index part is handled by functions which in
+turn use dynamically allocated index trees from RAM.
+These trees are updated by e.g. the etharp code
+when new entries are made or removed form the ARP cache.

+sys_arch interface for lwIP
+
+Author: Adam Dunkels
+        Simon Goldschmidt
+
+The operating system emulation layer provides a common interface
+between the lwIP code and the underlying operating system kernel. The
+general idea is that porting lwIP to new architectures requires only
+small changes to a few header files and a new sys_arch
+implementation. It is also possible to do a sys_arch implementation
+that does not rely on any underlying operating system.
+
+The sys_arch provides semaphores, mailboxes and mutexes to lwIP. For the full
+lwIP functionality, multiple threads support can be implemented in the
+sys_arch, but this is not required for the basic lwIP
+functionality. Timer scheduling is implemented in lwIP, but can be implemented
+by the sys_arch port (LWIP_TIMERS_CUSTOM==1).
+
+In addition to the source file providing the functionality of sys_arch,
+the OS emulation layer must provide several header files defining
+macros used throughout lwip.  The files required and the macros they
+must define are listed below the sys_arch description.
+
+Semaphores can be either counting or binary - lwIP works with both
+kinds. Mailboxes should be implemented as a queue which allows multiple messages
+to be posted (implementing as a rendez-vous point where only one message can be
+posted at a time can have a highly negative impact on performance). A message
+in a mailbox is just a pointer, nothing more. 
+
+Semaphores are represented by the type "sys_sem_t" which is typedef'd
+in the sys_arch.h file. Mailboxes are equivalently represented by the
+type "sys_mbox_t". Mutexes are represented by the type "sys_mutex_t".
+lwIP does not place any restrictions on how these types are represented
+internally.
+
+Since lwIP 1.4.0, semaphore, mutexes and mailbox functions are prototyped in a way that
+allows both using pointers or actual OS structures to be used. This way, memory
+required for such types can be either allocated in place (globally or on the
+stack) or on the heap (allocated internally in the "*_new()" functions).
+
+The following functions must be implemented by the sys_arch:
+
+- void sys_init(void)
+
+  Is called to initialize the sys_arch layer.
+
+- err_t sys_sem_new(sys_sem_t *sem, u8_t count)
+
+  Creates a new semaphore. The semaphore is allocated to the memory that 'sem'
+  points to (which can be both a pointer or the actual OS structure).
+  The "count" argument specifies the initial state of the semaphore (which is
+  either 0 or 1).
+  If the semaphore has been created, ERR_OK should be returned. Returning any
+  other error will provide a hint what went wrong, but except for assertions,
+  no real error handling is implemented.
+
+- void sys_sem_free(sys_sem_t *sem)
+
+  Deallocates a semaphore.
+
+- void sys_sem_signal(sys_sem_t *sem)
+
+  Signals a semaphore.
+
+- u32_t sys_arch_sem_wait(sys_sem_t *sem, u32_t timeout)
+
+  Blocks the thread while waiting for the semaphore to be
+  signaled. If the "timeout" argument is non-zero, the thread should
+  only be blocked for the specified time (measured in
+  milliseconds). If the "timeout" argument is zero, the thread should be
+  blocked until the semaphore is signalled.
+
+  If the timeout argument is non-zero, the return value is the number of
+  milliseconds spent waiting for the semaphore to be signaled. If the
+  semaphore wasn't signaled within the specified time, the return value is
+  SYS_ARCH_TIMEOUT. If the thread didn't have to wait for the semaphore
+  (i.e., it was already signaled), the function may return zero.
+
+  Notice that lwIP implements a function with a similar name,
+  sys_sem_wait(), that uses the sys_arch_sem_wait() function.
+
+- int sys_sem_valid(sys_sem_t *sem)
+
+  Returns 1 if the semaphore is valid, 0 if it is not valid.
+  When using pointers, a simple way is to check the pointer for != NULL.
+  When directly using OS structures, implementing this may be more complex.
+  This may also be a define, in which case the function is not prototyped.
+
+- void sys_sem_set_invalid(sys_sem_t *sem)
+
+  Invalidate a semaphore so that sys_sem_valid() returns 0.
+  ATTENTION: This does NOT mean that the semaphore shall be deallocated:
+  sys_sem_free() is always called before calling this function!
+  This may also be a define, in which case the function is not prototyped.
+
+- void sys_mutex_new(sys_mutex_t *mutex)
+
+  Creates a new mutex. The mutex is allocated to the memory that 'mutex'
+  points to (which can be both a pointer or the actual OS structure).
+  If the mutex has been created, ERR_OK should be returned. Returning any
+  other error will provide a hint what went wrong, but except for assertions,
+  no real error handling is implemented.
+
+- void sys_mutex_free(sys_mutex_t *mutex)
+
+  Deallocates a mutex.
+
+- void sys_mutex_lock(sys_mutex_t *mutex)
+  
+  Blocks the thread until the mutex can be grabbed.
+
+- void sys_mutex_unlock(sys_mutex_t *mutex)
+
+  Releases the mutex previously locked through 'sys_mutex_lock()'.
+
+- void sys_mutex_valid(sys_mutex_t *mutex)
+
+  Returns 1 if the mutes is valid, 0 if it is not valid.
+  When using pointers, a simple way is to check the pointer for != NULL.
+  When directly using OS structures, implementing this may be more complex.
+  This may also be a define, in which case the function is not prototyped.
+
+- void sys_mutex_set_invalid(sys_mutex_t *mutex)
+
+  Invalidate a mutex so that sys_mutex_valid() returns 0.
+  ATTENTION: This does NOT mean that the mutex shall be deallocated:
+  sys_mutex_free() is always called before calling this function!
+  This may also be a define, in which case the function is not prototyped.
+
+- err_t sys_mbox_new(sys_mbox_t *mbox, int size)
+
+  Creates an empty mailbox for maximum "size" elements. Elements stored
+  in mailboxes are pointers. You have to define macros "_MBOX_SIZE"
+  in your lwipopts.h, or ignore this parameter in your implementation
+  and use a default size.
+  If the mailbox has been created, ERR_OK should be returned. Returning any
+  other error will provide a hint what went wrong, but except for assertions,
+  no real error handling is implemented.
+
+- void sys_mbox_free(sys_mbox_t *mbox)
+
+  Deallocates a mailbox. If there are messages still present in the
+  mailbox when the mailbox is deallocated, it is an indication of a
+  programming error in lwIP and the developer should be notified.
+
+- void sys_mbox_post(sys_mbox_t *mbox, void *msg)
+
+  Posts the "msg" to the mailbox. This function have to block until
+  the "msg" is really posted.
+
+- err_t sys_mbox_trypost(sys_mbox_t *mbox, void *msg)
+
+  Try to post the "msg" to the mailbox. Returns ERR_MEM if this one
+  is full, else, ERR_OK if the "msg" is posted.
+
+- u32_t sys_arch_mbox_fetch(sys_mbox_t *mbox, void **msg, u32_t timeout)
+
+  Blocks the thread until a message arrives in the mailbox, but does
+  not block the thread longer than "timeout" milliseconds (similar to
+  the sys_arch_sem_wait() function). If "timeout" is 0, the thread should
+  be blocked until a message arrives. The "msg" argument is a result
+  parameter that is set by the function (i.e., by doing "*msg =
+  ptr"). The "msg" parameter maybe NULL to indicate that the message
+  should be dropped.
+
+  The return values are the same as for the sys_arch_sem_wait() function:
+  Number of milliseconds spent waiting or SYS_ARCH_TIMEOUT if there was a
+  timeout.
+
+  Note that a function with a similar name, sys_mbox_fetch(), is
+  implemented by lwIP. 
+
+- u32_t sys_arch_mbox_tryfetch(sys_mbox_t *mbox, void **msg)
+
+  This is similar to sys_arch_mbox_fetch, however if a message is not
+  present in the mailbox, it immediately returns with the code
+  SYS_MBOX_EMPTY. On success 0 is returned.
+
+  To allow for efficient implementations, this can be defined as a
+  function-like macro in sys_arch.h instead of a normal function. For
+  example, a naive implementation could be:
+    #define sys_arch_mbox_tryfetch(mbox,msg) \
+      sys_arch_mbox_fetch(mbox,msg,1)
+  although this would introduce unnecessary delays.
+
+- int sys_mbox_valid(sys_mbox_t *mbox)
+
+  Returns 1 if the mailbox is valid, 0 if it is not valid.
+  When using pointers, a simple way is to check the pointer for != NULL.
+  When directly using OS structures, implementing this may be more complex.
+  This may also be a define, in which case the function is not prototyped.
+
+- void sys_mbox_set_invalid(sys_mbox_t *mbox)
+
+  Invalidate a mailbox so that sys_mbox_valid() returns 0.
+  ATTENTION: This does NOT mean that the mailbox shall be deallocated:
+  sys_mbox_free() is always called before calling this function!
+  This may also be a define, in which case the function is not prototyped.
+
+If threads are supported by the underlying operating system and if
+such functionality is needed in lwIP, the following function will have
+to be implemented as well:
+
+- sys_thread_t sys_thread_new(char *name, void (* thread)(void *arg), void *arg, int stacksize, int prio)
+
+  Starts a new thread named "name" with priority "prio" that will begin its
+  execution in the function "thread()". The "arg" argument will be passed as an
+  argument to the thread() function. The stack size to used for this thread is
+  the "stacksize" parameter. The id of the new thread is returned. Both the id
+  and the priority are system dependent.
+
+When lwIP is used from more than one context (e.g. from multiple threads OR from
+main-loop and from interrupts), the SYS_LIGHTWEIGHT_PROT protection SHOULD be enabled!
+
+- sys_prot_t sys_arch_protect(void)
+
+  This optional function does a "fast" critical region protection and returns
+  the previous protection level. This function is only called during very short
+  critical regions. An embedded system which supports ISR-based drivers might
+  want to implement this function by disabling interrupts. Task-based systems
+  might want to implement this by using a mutex or disabling tasking. This
+  function should support recursive calls from the same task or interrupt. In
+  other words, sys_arch_protect() could be called while already protected. In
+  that case the return value indicates that it is already protected.
+
+  sys_arch_protect() is only required if your port is supporting an operating
+  system.
+
+- void sys_arch_unprotect(sys_prot_t pval)
+
+  This optional function does a "fast" set of critical region protection to the
+  value specified by pval. See the documentation for sys_arch_protect() for
+  more information. This function is only required if your port is supporting
+  an operating system.
+
+For some configurations, you also need:
+
+- u32_t sys_now(void)
+
+  This optional function returns the current time in milliseconds (don't care
+  for wraparound, this is only used for time diffs).
+  Not implementing this function means you cannot use some modules (e.g. TCP
+  timestamps, internal timeouts for NO_SYS==1).
+
+
+Note:
+
+Be careful with using mem_malloc() in sys_arch. When malloc() refers to
+mem_malloc() you can run into a circular function call problem. In mem.c
+mem_init() tries to allcate a semaphore using mem_malloc, which of course
+can't be performed when sys_arch uses mem_malloc.
+

+Additional files required for the "OS support" emulation layer:
+-------------------------------------------------------------------------------
+
+cc.h       - Architecture environment, some compiler specific, some
+             environment specific (probably should move env stuff 
+             to sys_arch.h.)
+
+  Typedefs for the types used by lwip -
+    u8_t, s8_t, u16_t, s16_t, u32_t, s32_t, mem_ptr_t
+
+  Compiler hints for packing lwip's structures -
+    PACK_STRUCT_FIELD(x)
+    PACK_STRUCT_STRUCT
+    PACK_STRUCT_BEGIN
+    PACK_STRUCT_END
+
+  Platform specific diagnostic output -
+    LWIP_PLATFORM_DIAG(x)    - non-fatal, print a message.
+    LWIP_PLATFORM_ASSERT(x)  - fatal, print message and abandon execution.
+    Portability defines for printf formatters:
+    U16_F, S16_F, X16_F, U32_F, S32_F, X32_F, SZT_F
+
+  "lightweight" synchronization mechanisms -
+    SYS_ARCH_DECL_PROTECT(x) - declare a protection state variable.
+    SYS_ARCH_PROTECT(x)      - enter protection mode.
+    SYS_ARCH_UNPROTECT(x)    - leave protection mode.
+
+  If the compiler does not provide memset() this file must include a
+  definition of it, or include a file which defines it.
+
+  This file must either include a system-local <errno.h> which defines
+  the standard *nix error codes, or it should #define LWIP_PROVIDE_ERRNO
+  to make lwip/arch.h define the codes which are used throughout.
+
+
+perf.h     - Architecture specific performance measurement.
+  Measurement calls made throughout lwip, these can be defined to nothing.
+    PERF_START               - start measuring something.
+    PERF_STOP(x)             - stop measuring something, and record the result.
+
+sys_arch.h - Tied to sys_arch.c
+
+  Arch dependent types for the following objects:
+    sys_sem_t, sys_mbox_t, sys_thread_t,
+  And, optionally:
+    sys_prot_t
+

+	    The web page you are watching was served by a simple web
+	    server running on top of the lightweight TCP/IP stack <a
+	    href="http://www.sics.se/~adam/lwip/">lwIP</a>.
+	  </p>
+	  <p>
+	    lwIP is an open source implementation of the TCP/IP
+	    protocol suite that was originally written by <a
+	    href="http://www.sics.se/~adam/lwip/">Adam Dunkels
+	    of the Swedish Institute of Computer Science</a> but now is
+	    being actively developed by a team of developers
+	    distributed world-wide. Since it's release, lwIP has
+	    spurred a lot of interest and has been ported to several
+	    platforms and operating systems. lwIP can be used either
+	    with or without an underlying OS.
+	  </p>
+	  <p>
+	    The focus of the lwIP TCP/IP implementation is to reduce
+	    the RAM usage while still having a full scale TCP. This
+	    makes lwIP suitable for use in embedded systems with tens
+	    of kilobytes of free RAM and room for around 40 kilobytes
+	    of code ROM.
+	  </p>
+	  <p>
+	    More information about lwIP can be found at the lwIP
+	    homepage at <a
+	    href="http://savannah.nongnu.org/projects/lwip/">http://savannah.nongnu.org/projects/lwip/</a>
+	    or at the lwIP wiki at <a

+/**
+ * @defgroup httpd HTTP server
+ * @ingroup apps
+ *
+ * This httpd supports for a
+ * rudimentary server-side-include facility which will replace tags of the form
+ * <!--#tag--> in any file whose extension is .shtml, .shtm or .ssi with
+ * strings provided by an include handler whose pointer is provided to the
+ * module via function http_set_ssi_handler().
+ * Additionally, a simple common
+ * gateway interface (CGI) handling mechanism has been added to allow clients
+ * to hook functions to particular request URIs.
+ *
+ * To enable SSI support, define label LWIP_HTTPD_SSI in lwipopts.h.
+ * To enable CGI support, define label LWIP_HTTPD_CGI in lwipopts.h.
+ *
+ * By default, the server assumes that HTTP headers are already present in
+ * each file stored in the file system.  By defining LWIP_HTTPD_DYNAMIC_HEADERS in
+ * lwipopts.h, this behavior can be changed such that the server inserts the
+ * headers automatically based on the extension of the file being served.  If
+ * this mode is used, be careful to ensure that the file system image used
+ * does not already contain the header information.
+ *
+ * File system images without headers can be created using the makefsfile
+ * tool with the -h command line option.
+ *
+ *
+ * Notes about valid SSI tags
+ * --------------------------
+ *
+ * The following assumptions are made about tags used in SSI markers:
+ *
+ * 1. No tag may contain '-' or whitespace characters within the tag name.
+ * 2. Whitespace is allowed between the tag leadin "<!--#" and the start of
+ *    the tag name and between the tag name and the leadout string "-->".
+ * 3. The maximum tag name length is LWIP_HTTPD_MAX_TAG_NAME_LEN, currently 8 characters.
+ *
+ * Notes on CGI usage
+ * ------------------
+ *
+ * The simple CGI support offered here works with GET method requests only
+ * and can handle up to 16 parameters encoded into the URI. The handler
+ * function may not write directly to the HTTP output but must return a
+ * filename that the HTTP server will send to the browser as a response to
+ * the incoming CGI request.
+ *
+ *
+ *
+ * The list of supported file types is quite short, so if makefsdata complains
+ * about an unknown extension, make sure to add it (and its doctype) to
+ * the 'g_psHTTPHeaders' list.

+This directory contains a script ('makefsdata') to create C code suitable for
+httpd for given html pages (or other files) in a directory.
+
+There is also a plain C console application doing the same and extended a bit.
+
+Usage: htmlgen [targetdir] [-s] [-i]s
+   targetdir: relative or absolute path to files to convert
+   switch -s: toggle processing of subdirectories (default is on)
+   switch -e: exclude HTTP header from file (header is created at runtime, default is on)
+   switch -11: include HTTP 1.1 header (1.0 is default)
+
+  if targetdir not specified, makefsdata will attempt to
+  process files in subdirectory 'fs'.

+ * @defgroup snmp SNMPv2c agent
+ * @ingroup apps
+ * SNMPv2c compatible agent\n
+ * There is also a MIB compiler and a MIB viewer in lwIP contrib repository
+ * (lwip-contrib/apps/LwipMibCompiler).\n
+ * The agent implements the most important MIB2 MIBs including IPv6 support
+ * (interfaces, UDP, TCP, SNMP, ICMP, SYSTEM). IP MIB is an older version
+ * whithout IPv6 statistics (TODO).\n
+ * Rewritten by Martin Hentschel <info@cl-soft.de> and
+ * Dirk Ziegelmeier <dziegel@gmx.de>\n
+ * Work on SNMPv3 has started, but is not finished.\n
+ *
+ * 0 Agent Capabilities
+ * ====================
+ * 
+ * Features:
+ * ---------
+ * - SNMPv2c support.
+ * - Low RAM usage - no memory pools, stack only.
+ * - MIB2 implementation is separated from SNMP stack.
+ * - Support for multiple MIBs (snmp_set_mibs() call) - e.g. for private MIB.
+ * - Simple and generic API for MIB implementation.
+ * - Comfortable node types and helper functions for scalar arrays and tables.
+ * - Counter64, bit and truthvalue datatype support.
+ * - Callbacks for SNMP writes e.g. to implement persistency.
+ * - Runs on two APIs: RAW and netconn.
+ * - Async API is gone - the stack now supports netconn API instead,
+ *   so blocking operations can be done in MIB calls.
+ *   SNMP runs in a worker thread when netconn API is used.
+ * - Simplified thread sync support for MIBs - useful when MIBs
+ *   need to access variables shared with other threads where no locking is
+ *   possible. Used in MIB2 to access lwIP stats from lwIP thread.
+ * 
+ * MIB compiler (code generator):
+ * ------------------------------
+ * - Provided in lwIP contrib repository.
+ * - Written in C#. MIB viewer used Windows Forms.
+ * - Developed on Windows with Visual Studio 2010.
+ * - Can be compiled and used on all platforms with http://www.monodevelop.com/.
+ * - Based on a heavily modified version of of SharpSnmpLib (a4bd05c6afb4)
+ *   (https://sharpsnmplib.codeplex.com/SourceControl/network/forks/Nemo157/MIBParserUpdate).
+ * - MIB parser, C file generation framework and LWIP code generation are cleanly
+ *   separated, which means the code may be useful as a base for code generation
+ *   of other SNMP agents.
+ * 
+ * Notes:
+ * ------
+ * - Stack and MIB compiler were used to implement a Profinet device.
+ *   Compiled/implemented MIBs: LLDP-MIB, LLDP-EXT-DOT3-MIB, LLDP-EXT-PNO-MIB.
+ * 
+ * SNMPv1 per RFC1157 and SNMPv2c per RFC 3416
+ * -------------------------------------------
+ *   Note the S in SNMP stands for "Simple". Note that "Simple" is
+ *   relative. SNMP is simple compared to the complex ISO network
+ *   management protocols CMIP (Common Management Information Protocol)
+ *   and CMOT (CMip Over Tcp).
+ * 
+ * MIB II
+ * ------
+ *   The standard lwIP stack management information base.
+ *   This is a required MIB, so this is always enabled.
+ *   The groups EGP, CMOT and transmission are disabled by default.
+ * 
+ *   Most mib-2 objects are not writable except:
+ *   sysName, sysLocation, sysContact, snmpEnableAuthenTraps.
+ *   Writing to or changing the ARP and IP address and route
+ *   tables is not possible.
+ * 
+ *   Note lwIP has a very limited notion of IP routing. It currently
+ *   doen't have a route table and doesn't have a notion of the U,G,H flags.
+ *   Instead lwIP uses the interface list with only one default interface
+ *   acting as a single gateway interface (G) for the default route.
+ * 
+ *   The agent returns a "virtual table" with the default route 0.0.0.0
+ *   for the default interface and network routes (no H) for each
+ *   network interface in the netif_list.
+ *   All routes are considered to be up (U).
+ * 
+ * Loading additional MIBs
+ * -----------------------
+ *   MIBs can only be added in compile-time, not in run-time.
+ *  
+ * 
+ * 1 Building the Agent
+ * ====================
+ * First of all you'll need to add the following define
+ * to your local lwipopts.h:
+ * \#define LWIP_SNMP               1
+ * 
+ * and add the source files your makefile.
+ * 
+ * Note you'll might need to adapt you network driver to update
+ * the mib2 variables for your interface.
+ * 
+ * 2 Running the Agent
+ * ===================
+ * The following function calls must be made in your program to
+ * actually get the SNMP agent running.
+ * 
+ * Before starting the agent you should supply pointers
+ * for sysContact, sysLocation, and snmpEnableAuthenTraps.
+ * You can do this by calling
+ * 
+ * - snmp_mib2_set_syscontact()
+ * - snmp_mib2_set_syslocation()
+ * - snmp_set_auth_traps_enabled()
+ * 
+ * You can register a callback which is called on successful write access: 
+ * snmp_set_write_callback().
+ * 
+ * Additionally you may want to set
+ * 
+ * - snmp_mib2_set_sysdescr()
+ * - snmp_set_device_enterprise_oid()
+ * - snmp_mib2_set_sysname()
+ * 
+ * Also before starting the agent you need to setup
+ * one or more trap destinations using these calls:
+ * 
+ * - snmp_trap_dst_enable()
+ * - snmp_trap_dst_ip_set()
+ * 
+ * If you need more than MIB2, set the MIBs you want to use
+ * by snmp_set_mibs().
+ * 
+ * Finally, enable the agent by calling snmp_init()
+ *

+ * @file
+ * Common functions used throughout the stack.
+ *
+ * These are reference implementations of the byte swapping functions.
+ * Again with the aim of being simple, correct and fully portable.
+ * Byte swapping is the second thing you would want to optimize. You will
+ * need to port it to your architecture and in your cc.h:
+ *
+ * \#define lwip_htons(x) your_htons
+ * \#define lwip_htonl(x) your_htonl
+ *
+ * Note lwip_ntohs() and lwip_ntohl() are merely references to the htonx counterparts.
+ * 
+ * If you \#define them to htons() and htonl(), you should
+ * \#define LWIP_DONT_PROVIDE_BYTEORDER_FUNCTIONS to prevent lwIP from
+ * defining htonx/ntohx compatibility macros.
+
+ * @defgroup sys_nonstandard Non-standard functions
+ * @ingroup sys_layer
+ * lwIP provides default implementations for non-standard functions.
+ * These can be mapped to OS functions to reduce code footprint if desired.
+ * All defines related to this section must not be placed in lwipopts.h,
+ * but in arch/cc.h!
+ * These options cannot be \#defined in lwipopts.h since they are not options
+ * of lwIP itself, but options of the lwIP port to your system.

+/**
+ * @file
+ * DNS - host name to IP address resolver.
+ *
+ * @defgroup dns DNS
+ * @ingroup callbackstyle_api
+ *
+ * Implements a DNS host name to IP address resolver.
+ *
+ * The lwIP DNS resolver functions are used to lookup a host name and
+ * map it to a numerical IP address. It maintains a list of resolved
+ * hostnames that can be queried with the dns_lookup() function.
+ * New hostnames can be resolved using the dns_query() function.
+ *
+ * The lwIP version of the resolver also adds a non-blocking version of
+ * gethostbyname() that will work with a raw API application. This function
+ * checks for an IP address string first and converts it if it is valid.
+ * gethostbyname() then does a dns_lookup() to see if the name is
+ * already in the table. If so, the IP is returned. If not, a query is
+ * issued and the function returns with a ERR_INPROGRESS status. The app
+ * using the dns client must then go into a waiting state.
+ *
+ * Once a hostname has been resolved (or found to be non-existent),
+ * the resolver code calls a specified callback function (which
+ * must be implemented by the module that uses the resolver).
+ * 
+ * Multicast DNS queries are supported for names ending on ".local".
+ * However, only "One-Shot Multicast DNS Queries" are supported (RFC 6762
+ * chapter 5.1), this is not a fully compliant implementation of continuous
+ * mDNS querying!
+ *
+ * All functions must be called from TCPIP thread.
+ * 
+ * @see @ref netconn_common for thread-safe access.

+/**
+ * @defgroup pbuf Packet buffers (PBUF)
+ * @ingroup infrastructure
+ *
+ * Packets are built from the pbuf data structure. It supports dynamic
+ * memory allocation for packet contents or can reference externally
+ * managed packet contents both in RAM and ROM. Quick allocation for
+ * incoming packets is provided through pools with fixed sized pbufs.
+ *
+ * A packet may span over multiple pbufs, chained as a singly linked
+ * list. This is called a "pbuf chain".
+ *
+ * Multiple packets may be queued, also using this singly linked list.
+ * This is called a "packet queue".
+ *
+ * So, a packet queue consists of one or more pbuf chains, each of
+ * which consist of one or more pbufs. CURRENTLY, PACKET QUEUES ARE
+ * NOT SUPPORTED!!! Use helper structs to queue multiple packets.
+ *
+ * The differences between a pbuf chain and a packet queue are very
+ * precise but subtle.
+ *
+ * The last pbuf of a packet has a ->tot_len field that equals the
+ * ->len field. It can be found by traversing the list. If the last
+ * pbuf of a packet has a ->next field other than NULL, more packets
+ * are on the queue.
+ *
+ * Therefore, looping through a pbuf of a single packet, has an
+ * loop end condition (tot_len == p->len), NOT (next == NULL).
+ *
+ * Example of custom pbuf usage for zero-copy RX:
+  @code{.c}

+ *             being used in a single thread. If the pbuf gets queued,

+ * SNMP output message processing (RFC1157).
+ *
+ * Output responses and traps are build in two passes:
+ *
+ * Pass 0: iterate over the output message backwards to determine encoding lengths
+ * Pass 1: the actual forward encoding of internal form into ASN1
+ *
+ * The single-pass encoding method described by Comer & Stevens
+ * requires extra buffer space and copying for reversal of the packet.
+ * The buffer requirement can be prohibitively large for big payloads
+ * (>= 484) therefore we use the two encoding passes.

+ * In the netconn implementation, there are three ways to block a client:

+ * - accept mbox (sys_arch_mbox_fetch(&conn->acceptmbox, &accept_ptr, 0); in netconn_accept())
+ * - receive mbox (sys_arch_mbox_fetch(&conn->recvmbox, &buf, 0); in netconn_recv_data())
+ * - send queue is full (sys_arch_sem_wait(LWIP_API_MSG_SEM(msg), 0); in lwip_netconn_do_write())
+ * 
+ * The events have to be seen as events signaling the state of these mboxes/semaphores. For non-blocking
+ * connections, you need to know in advance whether a call to a netconn function call would block or not,
+ * and these events tell you about that.
+ * 
+ * RCVPLUS events say: Safe to perform a potentially blocking call call once more. 
+ * They are counted in sockets - three RCVPLUS events for accept mbox means you are safe
+ * to call netconn_accept 3 times without being blocked.
+ * Same thing for receive mbox.
+ * 
+ * RCVMINUS events say: Your call to to a possibly blocking function is "acknowledged".
+ * Socket implementation decrements the counter.
+ * 
+ * For TX, there is no need to count, its merely a flag. SENDPLUS means you may send something.
+ * SENDPLUS occurs when enough data was delivered to peer so netconn_send() can be called again.
+ * A SENDMINUS event occurs when the next call to a netconn_send() would be blocking.

+ * Compressed packet format:

+ * numbers have changed (bottom 5 bits).  The next octet is a
+ * conversation number that associates a saved IP/TCP header with
+ * the compressed packet.  The next two octets are the TCP checksum
+ * from the original datagram.  The next 0 to 15 octets are
+ * sequence number changes, one change per bit set in the header
+ * (there may be no changes and there are two special cases where
+ * the receiver implicitly knows what changed -- see below).
+ *
+ * There are 5 numbers which can change (they are always inserted
+ * in the following order): TCP urgent pointer, window,
+ * acknowlegement, sequence number and IP ID.  (The urgent pointer
+ * is different from the others in that its value is sent, not the
+ * change in value.)  Since typical use of SLIP links is biased
+ * toward small packets (see comments on MTU/MSS below), changes
+ * use a variable length coding with one octet for numbers in the
+ * range 1 - 255 and 3 octets (0, MSB, LSB) for numbers in the
+ * range 256 - 65535 or 0.  (If the change in sequence number or
+ * ack is more than 65535, an uncompressed packet is sent.)

+ * Packet types (must not conflict with IP protocol version)
+ *
+ * The top nibble of the first octet is the packet type.  There are
+ * three possible types: IP (not proto TCP or tcp with one of the
+ * control flags set); uncompressed TCP (a normal IP/TCP packet but
+ * with the 8-bit protocol field replaced by an 8-bit connection id --
+ * this type of packet syncs the sender & receiver); and compressed
+ * TCP (described above).
+ *
+ * LSB of 4-bit field is TCP "PUSH" bit (a worthless anachronism) and
+ * is logically part of the 4-bit "changes" field that follows.  Top
+ * three bits are actual packet type.  For backward compatibility
+ * and in the interest of conserving bits, numbers are chosen so the
+ * IP protocol version number (4) which normally appears in this nibble

+The lwIP PPP support is based from pppd 2.4.5 (http://ppp.samba.org) with
+huge changes to match code size and memory requirements for embedded devices.
+
+Anyway, pppd has a mature codebase for years and the average commit count
+is getting low on their Git repository, meaning that we can follow what
+is happening on their side and merge what is relevant for lwIP.
+
+So, here is the pppd follow up, so that we don't get away too far from pppd.
+
+
+== Patch fetched from from pppd Debian packages ==
+
+This has nothing to do with pppd, but we merged some good patch from
+Debian and this is a good place to be.
+
+- LCP adaptive echo, so that we don't send LCP echo request if we
+  are receiving data from peer, can be enabled by setting PPP_LCP_ADAPTIVE
+  to true.
+ 
+- IPCP no/replace default route option, were added in the early stage of
+  the ppp port, but it wasn't really helpful and was disabled when adding
+  the new API ppp_set_default() call, which gives the lwIP user control over
+  which one is the default interface, it was actually a requirement if you
+  are doing PPP over PPP (i.e. PPPoL2TP, VPN link, over PPPoE, ADSL link).
+
+- using rp-pppoe pppd exits with EXIT_OK after receiving a timeout waiting
+  for PADO due to no modem attached, bug reported to pppd bug tracker, fixed
+  in Debian but not in the latest (at the time when the port were started)
+  pppd release.
+
+
+== Commits on pppd ==
+
+2010-03-06 - Document +ipv6 and ipv6cp-accept-local

+
+2010-03-07 - rp_pppoe: Copy acName and pppd_pppoe_service after option parsing
+  cab58617fd9d328029fffabc788020264b4fa91f
+
+Don't care, is a patch for pppd/plugins/rp-pppoe/plugin.c which is not part
+of the port.
+
+
+2010-08-23 - set and reset options to control environment variables
+             for scripts.
+  2b6310fd24dba8e0fca8999916a162f0a1842a84
+
+We can't fork processes in embedded, therefore all the pppd process run
+feature is disabled in the port, so we don't care about the new
+"environment variables" pppd feature.
+
+
+2010-08-23 - Nit: use _exit when exec fails and restrict values to 0-255
+             per POSIX.
+  2b4ea140432eeba5a007c0d4e6236bd0e0c12ba4
+
+Again, we are not running as a heavy process, so all exit() or _exit() calls
+were removed.
+
+
+2010-08-23 - Fix quote handling in configuration files to be more like shell
+             quoting.
+  3089132cdf5b58dbdfc2daf08ec5c08eb47f8aca
+
+We are not parsing config file, all the filesystem I/O stuff were disabled
+in our port.
+
+
+2010-08-24 - rp-pppoe: allow MTU to be increased up to 1500
+  fd1dcdf758418f040da3ed801ab001b5e46854e7
+
+Only concern changes on RP-PPPoE plugin, which we don't use.
+
+
+2010-09-11 - chat: Allow TIMEOUT value to come from environment variable
+  ae80bf833e48a6202f44a935a68083ae52ad3824
+
+See 2b6310fd24dba8e0fca8999916a162f0a1842a84.
+
+
+2011-03-05 - pppdump: Fix printfs with insufficient arguments
+  7b8db569642c83ba3283745034f2e2c95e459423
+
+pppdump is a ppp tool outside pppd source tree.
+
+
+2012-05-06 - pppd: Don't unconditionally disable VJ compression under Linux
+  d8a66adf98a0e525cf38031b42098d539da6eeb6
+
+Patch for sys-linux.c, which we don't use.
+
+
+2012-05-20 - Remove old version of Linux if_pppol2tp.h

+  08ef47ca532294eb428238c831616748940e24a2
+
+This is an interesting patch. However it consumes much more memory for
+MSCHAP and I am not sure if the benefit worth it. The PPP client can
+always start the authentication again if it failed for whatever reason.
+
+
+2012-05-20 - scripts: Make poff ignore extra arguments to pppd
+  18f515f32c9f5723a9c2c912601e04335106534b
+
+Again, we are not running scripts.

+  845cda8fa18939cf56e60b073f63a7efa65336fc
+
+This is just a patch that adds plugins hooks for IPv6, the plugin interface
+was disabled because we don't have .so plugins in embedded.
+
+
+2012-05-20 - pppd: Enable IPV6 by default and fix some warnings
+  0b6118239615e98959f7e0b4e746bdd197533248
+
+Change on Makefile for IPv6, warnings were already cleared during port.
+

+  fe149de624f96629a7f46732055d8f718c74b856
+
+We never ported IPX support. lwIP does not support IPX.
+
+
+2015-03-25 - pppd: Fix ccp_options.mppe type
+  234edab99a6bb250cc9ecd384cca27b0c8b475ce
+
+We found that while working on MPPE support in lwIP, that's our patch ;-)
+
+
+2015-03-24 - pppd: Fix ccp_cilen calculated size if both deflate_correct and deflate_draft are enabled
+  094cb8ae4c61db225e67fedadb4964f846dd0c27
+
+We found that while working on MPPE support in lwIP, that's our patch ;-)

+ * Original version by James Carlson
+ *
+ * This implementation of EAP supports MD5-Challenge and SRP-SHA1
+ * authentication styles.  Note that support of MD5-Challenge is a
+ * requirement of RFC 2284, and that it's essentially just a
+ * reimplementation of regular RFC 1994 CHAP using EAP messages.
+ *
+ * As an authenticator ("server"), there are multiple phases for each
+ * style.  In the first phase of each style, the unauthenticated peer
+ * name is queried using the EAP Identity request type.  If the
+ * "remotename" option is used, then this phase is skipped, because
+ * the peer's name is presumed to be known.
+ *
+ * For MD5-Challenge, there are two phases, and the second phase
+ * consists of sending the challenge itself and handling the
+ * associated response.
+ *

+About PolarSSL files into lwIP PPP support
+------------------------------------------
+
+This folder contains some files fetched from the latest BSD release of
+the PolarSSL project (PolarSSL 0.10.1-bsd) for ciphers and encryption
+methods we need for lwIP PPP support.
+
+The PolarSSL files were cleaned to contain only the necessary struct
+fields and functions needed for lwIP.
+
+The PolarSSL API was not changed at all, so if you are already using
+PolarSSL you can choose to skip the compilation of the included PolarSSL
+library into lwIP.
+
+If you are not using the embedded copy you must include external
+libraries into your arch/cc.h port file.
+
+Beware of the stack requirements which can be a lot larger if you are not
+using our cleaned PolarSSL library.

+ *
+ * This is an arch independent SLIP netif. The specific serial hooks must be
+ * provided by another file. They are sio_open, sio_read/sio_tryread and sio_send
+ *
+ * Usage: This netif can be used in three ways:\n
+ *        1) For NO_SYS==0, an RX thread can be used which blocks on sio_read()
+ *           until data is received.\n
+ *        2) In your main loop, call slipif_poll() to check for new RX bytes,
+ *           completed packets are fed into netif->input().\n
+ *        3) Call slipif_received_byte[s]() from your serial RX ISR and
+ *           slipif_process_rxqueue() from your main loop. ISR level decodes
+ *           packets and puts completed packets on a queue which is fed into
+ *           the stack from the main loop (needs SYS_LIGHTWEIGHT_PROT for
+ *           pbuf_alloc to work on ISR level!).

+= mbed TLS 2.4.2 branch released 2017-03-08
+
+Security
+   * Add checks to prevent signature forgeries for very large messages while
+     using RSA through the PK module in 64-bit systems. The issue was caused by
+     some data loss when casting a size_t to an unsigned int value in the
+     functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
+     mbedtls_pk_sign(). Found by Jean-Philippe Aumasson.
+   * Fixed potential livelock during the parsing of a CRL in PEM format in
+     mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
+     characters after the footer could result in the execution of an infinite
+     loop. The issue can be triggered remotely. Found by Greg Zaverucha,
+     Microsoft.
+   * Removed MD5 from the allowed hash algorithms for CertificateRequest and
+     CertificateVerify messages, to prevent SLOTH attacks against TLS 1.2.
+     Introduced by interoperability fix for #513.
+   * Fixed a bug that caused freeing a buffer that was allocated on the stack,
+     when verifying the validity of a key on secp224k1. This could be
+     triggered remotely for example with a maliciously constructed certificate
+     and potentially could lead to remote code execution on some platforms.
+     Reported independently by rongsaws and Aleksandar Nikolic, Cisco Talos
+     team. #569 CVE-2017-2784
+
+Bugfix
+   * Fix output certificate verification flags set by x509_crt_verify_top() when
+     traversing a chain of trusted CA. The issue would cause both flags,
+     MBEDTLS_X509_BADCERT_NOT_TRUSTED and MBEDTLS_X509_BADCERT_EXPIRED, to be
+     set when the verification conditions are not met regardless of the cause.
+     Found by Harm Verhagen and inestlerode. #665 #561
+   * Fix the redefinition of macro ssl_set_bio to an undefined symbol
+     mbedtls_ssl_set_bio_timeout in compat-1.3.h, by removing it.
+     Found by omlib-lin. #673
+   * Fix unused variable/function compilation warnings in pem.c, x509_crt.c and
+     x509_csr.c that are reported when building mbed TLS with a config.h that
+     does not define MBEDTLS_PEM_PARSE_C. Found by omnium21. #562
+   * Fix incorrect renegotiation condition in ssl_check_ctr_renegotiate() that
+     would compare 64 bits of the record counter instead of 48 bits as indicated
+     in RFC 6347 Section 4.3.1. This could cause the execution of the
+     renegotiation routines at unexpected times when the protocol is DTLS. Found
+     by wariua. #687
+   * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing
+     the input string in PEM format to extract the different components. Found
+     by Eyal Itkin.
+   * Fixed potential arithmetic overflow in mbedtls_ctr_drbg_reseed() that could
+     cause buffer bound checks to be bypassed. Found by Eyal Itkin.
+   * Fixed potential arithmetic overflows in mbedtls_cipher_update() that could
+     cause buffer bound checks to be bypassed. Found by Eyal Itkin.
+   * Fixed potential arithmetic overflow in mbedtls_md2_update() that could
+     cause buffer bound checks to be bypassed. Found by Eyal Itkin.
+   * Fixed potential arithmetic overflow in mbedtls_base64_decode() that could
+     cause buffer bound checks to be bypassed. Found by Eyal Itkin.
+   * Fixed heap overreads in mbedtls_x509_get_time(). Found by Peng
+     Li/Yueh-Hsun Lin, KNOX Security, Samsung Research America.
+   * Fix potential memory leak in mbedtls_x509_crl_parse(). The leak was caused
+     by missing calls to mbedtls_pem_free() in cases when a
+     MBEDTLS_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
+     fix proposed by Guido Vranken. #722
+   * Fixed the templates used to generate project and solution files for Visual
+     Studio 2015 as well as the files themselves, to remove a build warning
+     generated in Visual Studio 2015. Reported by Steve Valliere. #742
+   * Fix a resource leak in ssl_cookie, when using MBEDTLS_THREADING_C.
+     Raised and fix suggested by Alan Gillingham in the mbed TLS forum. #771
+   * Fix 1 byte buffer overflow in mbedtls_mpi_write_string() when the MPI
+     number to write in hexadecimal is negative and requires an odd number of
+     digits. Found and fixed by Guido Vranken.
+   * Fix unlisted DES configuration dependency in some pkparse test cases. Found
+     by inestlerode. #555
+
+= mbed TLS 2.4.1 branch released 2016-12-13
+
+Changes
+   * Update to CMAC test data, taken from - NIST Special Publication 800-38B -
+     Recommendation for Block Cipher Modes of Operation: The CMAC Mode for
+     Authentication – October  2016
+
+= mbed TLS 2.4.0 branch released 2016-10-17
+
+Security
+   * Removed the MBEDTLS_SSL_AEAD_RANDOM_IV option, because it was not compliant
+     with RFC-5116 and could lead to session key recovery in very long TLS
+     sessions. "Nonce-Disrespecting Adversaries Practical Forgery Attacks on GCM in
+     TLS" - H. Bock, A. Zauner, S. Devlin, J. Somorovsky, P. Jovanovic.
+     https://eprint.iacr.org/2016/475.pdf
+   * Fixed potential stack corruption in mbedtls_x509write_crt_der() and
+     mbedtls_x509write_csr_der() when the signature is copied to the buffer
+     without checking whether there is enough space in the destination. The
+     issue cannot be triggered remotely. Found by Jethro Beekman.
+
+Features
+   * Added support for CMAC for AES and 3DES and AES-CMAC-PRF-128, as defined by
+     NIST SP 800-38B, RFC-4493 and RFC-4615.
+   * Added hardware entropy selftest to verify that the hardware entropy source
+     is functioning correctly.
+   * Added a script to print build environment info for diagnostic use in test
+     scripts, which is also now called by all.sh.
+   * Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the user to
+     configure the maximum length of a file path that can be buffered when
+     calling mbedtls_x509_crt_parse_path().
+   * Added a configuration file config-no-entropy.h that configures the subset of
+     library features that do not require an entropy source.
+   * Added the macro MBEDTLS_ENTROPY_MIN_HARDWARE in config.h. This allows users
+     to configure the minimum number of bytes for entropy sources using the
+     mbedtls_hardware_poll() function.
+
+Bugfix
+   * Fix for platform time abstraction to avoid dependency issues where a build
+     may need time but not the standard C library abstraction, and added
+     configuration consistency checks to check_config.h
+   * Fix dependency issue in Makefile to allow parallel builds.
+   * Fix incorrect handling of block lengths in crypt_and_hash.c sample program,
+     when GCM is used. Found by udf2457. #441
+   * Fix for key exchanges based on ECDH-RSA or ECDH-ECDSA which weren't
+     enabled unless others were also present. Found by David Fernandez. #428
+   * Fix for out-of-tree builds using CMake. Found by jwurzer, and fix based on
+     a contribution from Tobias Tangemann. #541
+   * Fixed cert_app.c sample program for debug output and for use when no root
+     certificates are provided.
+   * Fix conditional statement that would cause a 1 byte overread in
+     mbedtls_asn1_get_int(). Found and fixed by Guido Vranken. #599
+   * Fixed pthread implementation to avoid unintended double initialisations
+     and double frees. Found by Niklas Amnebratt.
+   * Fixed the sample applications gen_key.c, cert_req.c and cert_write.c for
+     builds where the configuration MBEDTLS_PEM_WRITE_C is not defined. Found
+     by inestlerode. #559.
+   * Fix mbedtls_x509_get_sig() to update the ASN1 type in the mbedtls_x509_buf
+     data structure until after error checks are successful. Found by
+     subramanyam-c. #622
+   * Fix documentation and implementation missmatch for function arguments of
+     mbedtls_gcm_finish(). Found by cmiatpaar. #602
+   * Guarantee that P>Q at RSA key generation. Found by inestlerode. #558
+   * Fix potential byte overread when verifying malformed SERVER_HELLO in
+     ssl_parse_hello_verify_request() for DTLS. Found by Guido Vranken.
+   * Fix check for validity of date when parsing in mbedtls_x509_get_time().
+     Found by subramanyam-c. #626
+   * Fix compatibility issue with Internet Explorer client authentication,
+     where the limited hash choices prevented the client from sending its
+     certificate. Found by teumas. #513
+   * Fix compilation without MBEDTLS_SELF_TEST enabled.
+
+Changes
+   * Extended test coverage of special cases, and added new timing test suite.
+   * Removed self-tests from the basic-built-test.sh script, and added all
+     missing self-tests to the test suites, to ensure self-tests are only
+     executed once.
+   * Added support for 3 and 4 byte lengths to mbedtls_asn1_write_len().
+   * Added support for a Yotta specific configuration file -
+     through the symbol YOTTA_CFG_MBEDTLS_TARGET_CONFIG_FILE.
+   * Added optimization for code space for X.509/OID based on configured
+     features. Contributed by Aviv Palivoda.
+   * Renamed source file library/net.c to library/net_sockets.c to avoid
+     naming collision in projects which also have files with the common name
+     net.c. For consistency, the corresponding header file, net.h, is marked as
+     deprecated, and its contents moved to net_sockets.h.
+   * Changed the strategy for X.509 certificate parsing and validation, to no
+     longer disregard certificates with unrecognised fields.
+
+= mbed TLS 2.3.0 branch released 2016-06-28
+
+Security
+   * Fix missing padding length check in mbedtls_rsa_rsaes_pkcs1_v15_decrypt
+     required by PKCS1 v2.2
+   * Fix potential integer overflow to buffer overflow in
+     mbedtls_rsa_rsaes_pkcs1_v15_encrypt and mbedtls_rsa_rsaes_oaep_encrypt
+     (not triggerable remotely in (D)TLS).
+   * Fix a potential integer underflow to buffer overread in 
+     mbedtls_rsa_rsaes_oaep_decrypt. It is not triggerable remotely in
+     SSL/TLS.
+
+Features
+   * Support for platform abstraction of the standard C library time()
+     function.
+
+Bugfix
+   * Fix bug in mbedtls_mpi_add_mpi() that caused wrong results when the three
+     arguments where the same (in-place doubling). Found and fixed by Janos
+     Follath. #309
+   * Fix potential build failures related to the 'apidoc' target, introduced
+     in the previous patch release. Found by Robert Scheck. #390 #391
+   * Fix issue in Makefile that prevented building using armar. #386
+   * Fix memory leak that occured only when ECJPAKE was enabled and ECDHE and
+     ECDSA was disabled in config.h . The leak didn't occur by default.
+   * Fix an issue that caused valid certificates to be rejected whenever an
+     expired or not yet valid certificate was parsed before a valid certificate
+     in the trusted certificate list.
+   * Fix bug in mbedtls_x509_crt_parse that caused trailing extra data in the 
+     buffer after DER certificates to be included in the raw representation.
+   * Fix issue that caused a hang when generating RSA keys of odd bitlength
+   * Fix bug in mbedtls_rsa_rsaes_pkcs1_v15_encrypt that made null pointer
+     dereference possible.
+   * Fix issue that caused a crash if invalid curves were passed to
+     mbedtls_ssl_conf_curves. #373
+   * Fix issue in ssl_fork_server which was preventing it from functioning. #429
+   * Fix memory leaks in test framework
+   * Fix test in ssl-opt.sh that does not run properly with valgrind
+   * Fix unchecked calls to mmbedtls_md_setup(). Fix by Brian Murray. #502
+
+Changes
+   * On ARM platforms, when compiling with -O0 with GCC, Clang or armcc5,
+     don't use the optimized assembly for bignum multiplication. This removes
+     the need to pass -fomit-frame-pointer to avoid a build error with -O0.
+   * Disabled SSLv3 in the default configuration.
+   * Optimized mbedtls_mpi_zeroize() for MPI integer size. (Fix by Alexey
+     Skalozub).
+   * Fix non-compliance server extension handling. Extensions for SSLv3 are now
+     ignored, as required by RFC6101.
+
+= mbed TLS 2.2.1 released 2016-01-05
+
+Security
+   * Fix potential double free when mbedtls_asn1_store_named_data() fails to
+     allocate memory. Only used for certificate generation, not triggerable
+     remotely in SSL/TLS. Found by Rafał Przywara. #367
+   * Disable MD5 handshake signatures in TLS 1.2 by default to prevent the
+     SLOTH attack on TLS 1.2 server authentication (other attacks from the
+     SLOTH paper do not apply to any version of mbed TLS or PolarSSL).
+     https://www.mitls.org/pages/attacks/SLOTH
+
+Bugfix
+   * Fix over-restrictive length limit in GCM. Found by Andreas-N. #362
+   * Fix bug in certificate validation that caused valid chains to be rejected
+     when the first intermediate certificate has pathLenConstraint=0. Found by
+     Nicholas Wilson. Introduced in mbed TLS 2.2.0. #280
+   * Removed potential leak in mbedtls_rsa_rsassa_pkcs1_v15_sign(), found by
+     JayaraghavendranK. #372
+   * Fix suboptimal handling of unexpected records that caused interop issues
+     with some peers over unreliable links. Avoid dropping an entire DTLS
+     datagram if a single record in a datagram is unexpected, instead only
+     drop the record and look at subsequent records (if any are present) in
+     the same datagram. Found by jeannotlapin. #345
+
+= mbed TLS 2.2.0 released 2015-11-04
+
+Security
+   * Fix potential double free if mbedtls_ssl_conf_psk() is called more than
+     once and some allocation fails. Cannot be forced remotely. Found by Guido
+     Vranken, Intelworks.
+   * Fix potential heap corruption on Windows when
+     mbedtls_x509_crt_parse_path() is passed a path longer than 2GB. Cannot be
+     triggered remotely. Found by Guido Vranken, Intelworks.
+   * Fix potential buffer overflow in some asn1_write_xxx() functions.
+     Cannot be triggered remotely unless you create X.509 certificates based
+     on untrusted input or write keys of untrusted origin. Found by Guido
+     Vranken, Intelworks.
+   * The X509 max_pathlen constraint was not enforced on intermediate
+     certificates. Found by Nicholas Wilson, fix and tests provided by
+     Janos Follath. #280 and #319
+
+Features
+   * Experimental support for EC J-PAKE as defined in Thread 1.0.0.
+     Disabled by default as the specification might still change.
+   * Added a key extraction callback to accees the master secret and key
+     block. (Potential uses include EAP-TLS and Thread.)
+
+Bugfix
+   * Self-signed certificates were not excluded from pathlen counting,
+     resulting in some valid X.509 being incorrectly rejected. Found and fix
+     provided by Janos Follath. #319
+   * Fix build error with configurations where ECDHE-PSK is the only key
+     exchange. Found and fix provided by Chris Hammond. #270
+   * Fix build error with configurations where RSA, RSA-PSK, ECDH-RSA or
+     ECHD-ECDSA if the only key exchange. Multiple reports. #310
+   * Fixed a bug causing some handshakes to fail due to some non-fatal alerts
+     not being properly ignored. Found by mancha and Kasom Koht-arsa, #308
+   * mbedtls_x509_crt_verify(_with_profile)() now also checks the key type and
+     size/curve against the profile. Before that, there was no way to set a
+     minimum key size for end-entity certificates with RSA keys. Found by
+     Matthew Page of Scannex Electronics Ltd.
+   * Fix failures in MPI on Sparc(64) due to use of bad assembly code.
+     Found by Kurt Danielson. #292
+   * Fix typo in name of the extKeyUsage OID. Found by inestlerode, #314
+   * Fix bug in ASN.1 encoding of booleans that caused generated CA
+     certificates to be rejected by some applications, including OS X
+     Keychain. Found and fixed by Jonathan Leroy, Inikup.
+
+Changes
+   * Improved performance of mbedtls_ecp_muladd() when one of the scalars is 1
+     or -1.
+
+= mbed TLS 2.1.2 released 2015-10-06
+
+Security
+   * Added fix for CVE-2015-5291 to prevent heap corruption due to buffer
+     overflow of the hostname or session ticket. Found by Guido Vranken,

+   * Expanded configurability of security parameters in the SSL module with
+     mbedtls_ssl_conf_dhm_min_bitlen() and mbedtls_ssl_conf_sig_hashes().
+   * Introduced a concept of presets for SSL security-relevant configuration
+     parameters.
+
+API Changes
+   * The library has been split into libmbedcrypto, libmbedx509, libmbedtls.
+     You now need to link to all of them if you use TLS for example.
+   * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
+     Some names have been further changed to make them more consistent.
+     Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
+     provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
+   * Renamings of fields inside structures, not covered by the previous list:
+     mbedtls_cipher_info_t.key_length -> key_bitlen
+     mbedtls_cipher_context_t.key_length -> key_bitlen
+     mbedtls_ecp_curve_info.size -> bit_size
+   * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
+   * The following _init() functions that could return errors have
+     been split into an _init() that returns void and another function that
+     should generally be the first function called on this context after init:
+     mbedtls_ssl_init() -> mbedtls_ssl_setup()
+     mbedtls_ccm_init() -> mbedtls_ccm_setkey()
+     mbedtls_gcm_init() -> mbedtls_gcm_setkey()
+     mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)()
+     mbedtls_ctr_drbg_init()  -> mbedtls_ctr_drbg_seed()
+     Note that for mbedtls_ssl_setup(), you need to be done setting up the
+     ssl_config structure before calling it.
+   * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
+     ssl_set_session() and ssl_set_client_transport_id(), plus
+     ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
+     (see rename.pl and compat-1.3.h above) and their first argument's type
+     changed from ssl_context to ssl_config.
+   * ssl_set_bio() changed signature (contexts merged, order switched, one
+     additional callback for read-with-timeout).
+   * The following functions have been introduced and must be used in callback
+     implementations (SNI, PSK) instead of their *conf counterparts:
+     mbedtls_ssl_set_hs_own_cert()
+     mbedtls_ssl_set_hs_ca_chain()
+     mbedtls_ssl_set_hs_psk()
+   * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
+     using mbedtls_ssl_set_hostname().
+   * mbedtls_ssl_conf_session_cache() changed prototype (only one context
+     pointer, parameters reordered).
+   * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
+     place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
+   * The SSL debug callback gained two new arguments (file name, line number).
+   * Debug modes were removed.
+   * mbedtls_ssl_conf_truncated_hmac() now returns void.
+   * mbedtls_memory_buffer_alloc_init() now returns void.
+   * X.509 verification flags are now an uint32_t. Affect the signature of:
+     mbedtls_ssl_get_verify_result()
+     mbedtls_x509_ctr_verify_info()
+     mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
+     mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
+   * The following functions changed prototype to avoid an in-out length
+     parameter:
+     mbedtls_base64_encode()
+     mbedtls_base64_decode()
+     mbedtls_mpi_write_string()
+     mbedtls_dhm_calc_secret()
+   * In the NET module, all "int" and "int *" arguments for file descriptors
+     changed type to "mbedtls_net_context *".
+   * net_accept() gained new arguments for the size of the client_ip buffer.
+   * In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now
+     return void.
+   * ecdsa_write_signature() gained an addtional md_alg argument and
+     ecdsa_write_signature_det() was deprecated.
+   * pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
+   * Last argument of x509_crt_check_key_usage() and
+     mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
+   * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
+     available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
+   * Test certificates in certs.c are no longer guaranteed to be nul-terminated
+     strings; use the new *_len variables instead of strlen().
+   * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
+     mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
+     length parameter to include the terminating null byte for PEM input.
+   * Signature of mpi_mul_mpi() changed to make the last argument unsigned
+   * calloc() is now used instead of malloc() everywhere. API of platform
+     layer and the memory_buffer_alloc module changed accordingly.
+     (Thanks to Mansour Moufid for helping with the replacement.)
+   * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
+     (support for renegotiation now needs explicit enabling in config.h).
+   * Split MBEDTLS_HAVE_TIME into MBEDTLS_HAVE_TIME and MBEDTLS_HAVE_TIME_DATE
+     in config.h
+   * net_connect() and net_bind() have a new 'proto' argument to choose
+     between TCP and UDP, using the macros NET_PROTO_TCP or NET_PROTO_UDP.
+     Their 'port' argument type is changed to a string.
+   * Some constness fixes
+
+Removals
+   * Removed mbedtls_ecp_group_read_string(). Only named groups are supported.
+   * Removed mbedtls_ecp_sub() and mbedtls_ecp_add(), use

+   * Removed test DHM parameters from the test certs module.
+   * Removed the PBKDF2 module (use PKCS5).
+   * Removed POLARSSL_ERROR_STRERROR_BC (use mbedtls_strerror()).
+   * Removed compat-1.2.h (helper for migrating from 1.2 to 1.3).
+   * Removed openssl.h (very partial OpenSSL compatibility layer).
+   * Configuration options POLARSSL_HAVE_LONGLONG was removed (now always on).
+   * Configuration options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 have
+     been removed (compiler is required to support 32-bit operations).
+   * Configuration option POLARSSL_HAVE_IPV6 was removed (always enabled).
+   * Removed test program o_p_test, the script compat.sh does more.
+   * Removed test program ssl_test, superseded by ssl-opt.sh.
+   * Removed helper script active-config.pl
+
+New deprecations
+   * md_init_ctx() is deprecated in favour of md_setup(), that adds a third
+     argument (allowing memory savings if HMAC is not used)
+
+Semi-API changes (technically public, morally private)
+   * Renamed a few headers to include _internal in the name. Those headers are
+     not supposed to be included by users.
+   * Changed md_info_t into an opaque structure (use md_get_xxx() accessors).
+   * Changed pk_info_t into an opaque structure.
+   * Changed cipher_base_t into an opaque structure.
+   * Removed sig_oid2 and rename sig_oid1 to sig_oid in x509_crt and x509_crl.
+   * x509_crt.key_usage changed from unsigned char to unsigned int.
+   * Removed r and s from ecdsa_context
+   * Removed mode from des_context and des3_context
+
+Default behavior changes
+   * The default minimum TLS version is now TLS 1.0.
+   * RC4 is now blacklisted by default in the SSL/TLS layer, and excluded from the
+     default ciphersuite list returned by ssl_list_ciphersuites()
+   * Support for receiving SSLv2 ClientHello is now disabled by default at
+     compile time.
+   * The default authmode for SSL/TLS clients is now REQUIRED.
+   * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
+     enabled in the default configuration, this is only noticeable if using a
+     custom config.h
+   * Default DHM parameters server-side upgraded from 1024 to 2048 bits.
+   * A minimum RSA key size of 2048 bits is now enforced during ceritificate
+     chain verification.
+   * Negotiation of truncated HMAC is now disabled by default on server too.
+   * The following functions are now case-sensitive:
+     mbedtls_cipher_info_from_string()
+     mbedtls_ecp_curve_info_from_name()
+     mbedtls_md_info_from_string()
+     mbedtls_ssl_ciphersuite_from_string()
+     mbedtls_version_check_feature()
+
+Requirement changes
+   * The minimum MSVC version required is now 2010 (better C99 support).
+   * The NET layer now unconditionnaly relies on getaddrinfo() and select().
+   * Compiler is required to support C99 types such as long long and uint32_t.
+
+API changes from the 1.4 preview branch
+   * ssl_set_bio_timeout() was removed, split into mbedtls_ssl_set_bio() with
+     new prototype, and mbedtls_ssl_set_read_timeout().
+   * The following functions now return void:
+     mbedtls_ssl_conf_transport()
+     mbedtls_ssl_conf_max_version()
+     mbedtls_ssl_conf_min_version()
+   * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
+     instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
+     an example implementation, see mbedtls_timing_delay_context and
+     mbedtls_timing_set/get_delay().
+   * With UDP sockets, it is no longer necessary to call net_bind() again
+     after a successful net_accept().
+
+Changes
+   * mbedtls_ctr_drbg_random() and mbedtls_hmac_drbg_random() are now
+     thread-safe if MBEDTLS_THREADING_C is enabled.
+   * Reduced ROM fooprint of SHA-256 and added an option to reduce it even
+     more (at the expense of performance) MBEDTLS_SHA256_SMALLER.

+Security
+   * Fix remotely-triggerable uninitialised pointer dereference caused by
+     crafted X.509 certificate (TLS server is not affected if it doesn't ask
+     for a client certificate) (found using Codenomicon Defensics).

+= Version 0.99-pre5 released on 2011-05-26
+Features
+   * Added additional Cipher Block Modes to symmetric ciphers
+     (AES CTR, Camellia CTR, XTEA CBC) including the option to
+     enable and disable individual modes when needed
+   * Functions requiring File System functions can now be disabled
+     by undefining POLARSSL_FS_IO
+   * A error_strerror function() has been added to translate between
+     error codes and their description.
+   * Added mpi_get_bit() and mpi_set_bit() individual bit setter/getter
+     functions.
+   * Added ssl_mail_client and ssl_fork_server as example programs.
+
+Changes
+   * Major argument / variable rewrite. Introduced use of size_t
+     instead of int for buffer lengths and loop variables for
+     better unsigned / signed use. Renamed internal bigint types
+     t_int and t_dbl to t_uint and t_udbl in the process
+   * mpi_init() and mpi_free() now only accept a single MPI
+     argument and do not accept variable argument lists anymore.
+   * The error codes have been remapped and combining error codes
+     is now done with a PLUS instead of an OR as error codes
+     used are negative.
+   * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
+     net_recv() now returns 0 on EOF instead of
+     POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
+     POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
+     ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
+     after the handshake.
+   * Network functions now return POLARSSL_ERR_NET_WANT_READ or
+     POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
+     POLARSSL_ERR_NET_TRY_AGAIN
+

+
+Changes
+   * Debug print of MPI now removes leading zero octets and 
+     displays actual bit size of the value.
+   * x509parse_key() (and as a consequence x509parse_keyfile()) 
+     does not zeroize memory in advance anymore. Use rsa_init()
+     before parsing a key or keyfile!
+
+Bugfix
+   * Debug output of MPI's now the same independent of underlying
+     platform (32-bit / 64-bit) (Fixes ticket #19, found by Mads
+     Kiilerich and Mihai Militaru)

+README for mbed TLS
+===================
+
+Configuration
+-------------
+
+mbed TLS should build out of the box on most systems. Some platform specific options are available in the fully documented configuration file `include/mbedtls/config.h`, which is also the place where features can be selected. This file can be edited manually, or in a more programmatic way using the Perl script `scripts/config.pl` (use `--help` for usage instructions).
+
+Compiler options can be set using conventional environment variables such as `CC` and `CFLAGS` when using the Make and CMake build system (see below).
+
+Compiling
+---------
+
+There are currently four active build systems used within mbed TLS releases:
+
+-   yotta
+-   Make
+-   CMake
+-   Microsoft Visual Studio (Visual Studio 6 and Visual Studio 2010)
+
+The main systems used for development are CMake and Make. Those systems are always complete and up-to-date. The others should reflect all changes present in the CMake and Make build system, although features may not be ported there automatically.
+
+Yotta, as a build system, is slightly different from the other build systems:
+
+-   it provides a minimalistic configuration file by default
+-   depending on the yotta target, features of mbed OS may be used in examples and tests
+
+The Make and CMake build systems create three libraries: libmbedcrypto, libmbedx509, and libmbedtls. Note that libmbedtls depends on libmbedx509 and libmbedcrypto, and libmbedx509 depends on libmbedcrypto. As a result, some linkers will expect flags to be in a specific order, for example the GNU linker wants `-lmbedtls -lmbedx509 -lmbedcrypto`. Also, when loading shared libraries using dlopen(), you'll need to load libmbedcrypto first, then libmbedx509, before you can load libmbedtls.
+
+### Yotta
+
+[yotta](http://yottabuild.org) is a package manager and build system developed by mbed, and is the build system of mbed OS 16.03. To install it on your platform, please follow the yotta [installation instructions](http://docs.yottabuild.org/#installing).
+
+Once yotta is installed, you can use it to download the latest version of mbed TLS from the yotta registry with:
+
+    yotta install mbedtls
+
+and build it with:
+
+    yotta build
+
+If, on the other hand, you already have a copy of mbed TLS from a source other than the yotta registry, for example from cloning our GitHub repository, or from downloading a tarball of the standalone edition, then you'll first need to generate the yotta module by running:
+
+    yotta/create-module.sh
+
+This should be executed from the root mbed TLS project directory. This will create the yotta module in the `yotta/module` directory within it. You can then change to that directory and build as usual:
+
+    cd yotta/module
+    yotta build
+
+In any case, you'll probably want to set the yotta target before building unless it has already been set globally. For more information on using yotta, please consult the [yotta documentation](http://docs.yottabuild.org/).
+
+For more details on the yotta/mbed OS edition of mbed TLS, including example programs, please consult the [Readme at the root of the yotta module](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/README.md).
+
+### Make
+
+We intentionally only use the minimum of `Make` functionality, as a lot of `Make` features are not supported on all different implementations of Make or on different platforms. As such, the Makefiles sometimes require some manual changes or export statements in order to work for your platform.
+
+In order to build from the source code using Make, just enter at the command line:
+
+    make
+
+In order to run the tests, enter:
+
+    make check
+
+The tests need Perl to be built and run. If you don't have Perl installed, you can skip building the tests with:
+
+    make no_test
+
+You'll still be able to run a much smaller set of tests with:
+
+    programs/test/selftest
+
+In order to build for a Windows platform, you should use `WINDOWS_BUILD=1` if the target is Windows but the build environment is Unix-like (for instance when cross-compiling, or compiling from an MSYS shell), and `WINDOWS=1` if the build environment is a Windows shell (for instance using mingw32-make) (in that case some targets will not be available).
+
+Setting the variable `SHARED` in your environment will build shared libraries in addition to the static libraries. Setting `DEBUG` gives you a debug build. You can override `CFLAGS` and `LDFLAGS` by setting them in your environment or on the make command line; if you do so, essential parts such as `-I` will still be preserved. Warning options may be overridden separately using `WARNING_CFLAGS`.
+
+Depending on your platform, you might run into some issues. Please check the Makefiles in `library/`, `programs/` and `tests/` for options to manually add or remove for specific platforms. You can also check [the mbed TLS Knowledge Base](https://tls.mbed.org/kb) for articles on your platform or issue.
+
+In case you find that you need to do something else as well, please let us know what, so we can add it to the [mbed TLS knowledge base](https://tls.mbed.org/kb).
+
+### CMake
+
+In order to build the source using CMake, just enter at the command line:
+
+    cmake .
+    make
+
+In order to run the tests, enter:
+
+    make test
+
+The test suites need Perl to be built. If you don't have Perl installed, you'll want to disable the test suites with:
+
+    cmake -DENABLE_TESTING=Off .
+
+If you disabled the test suites, but kept the programs enabled, you can still run a much smaller set of tests with:
+
+    programs/test/selftest
+
+To configure CMake for building shared libraries, use:
+
+    cmake -DUSE_SHARED_MBEDTLS_LIBRARY=On .
+
+There are many different build modes available within the CMake buildsystem. Most of them are available for gcc and clang, though some are compiler-specific:
+
+-   Release. This generates the default code without any unnecessary information in the binary files.
+-   Debug. This generates debug information and disables optimization of the code.
+-   Coverage. This generates code coverage information in addition to debug information.
+-   ASan. This instruments the code with AddressSanitizer to check for memory errors. (This includes LeakSanitizer, with recent version of gcc and clang.) (With recent version of clang, this mode also instruments the code with UndefinedSanitizer to check for undefined behaviour.)
+-   ASanDbg. Same as ASan but slower, with debug information and better stack traces.
+-   MemSan. This instruments the code with MemorySanitizer to check for uninitialised memory reads. Experimental, needs recent clang on Linux/x86\_64.
+-   MemSanDbg. Same as MemSan but slower, with debug information, better stack traces and origin tracking.
+-   Check. This activates the compiler warnings that depend on optimization and treats all warnings as errors.
+
+Switching build modes in CMake is simple. For debug mode, enter at the command line:
+
+    cmake -D CMAKE_BUILD_TYPE=Debug .
+
+To list other available CMake options, use:
+
+    cmake -LH
+
+Note that, with CMake, if you want to change the compiler or its options after you already ran CMake, you need to clear its cache first, e.g. (using GNU find):
+
+    find . -iname '*cmake*' -not -name CMakeLists.txt -exec rm -rf {} +
+    CC=gcc CFLAGS='-fstack-protector-strong -Wa,--noexecstack' cmake .
+
+### Microsoft Visual Studio
+
+The build files for Microsoft Visual Studio are generated for Visual Studio 2010.
+
+The solution file `mbedTLS.sln` contains all the basic projects needed to build the library and all the programs. The files in tests are not generated and compiled, as these need a perl environment as well. However, the selftest program in `programs/test/` is still available.
+
+Example programs
+----------------
+
+We've included example programs for a lot of different features and uses in `programs/`. Most programs only focus on a single feature or usage scenario, so keep that in mind when copying parts of the code.
+
+Tests
+-----
+
+mbed TLS includes an elaborate test suite in `tests/` that initially requires Perl to generate the tests files (e.g. `test\_suite\_mpi.c`). These files are generated from a `function file` (e.g. `suites/test\_suite\_mpi.function`) and a `data file` (e.g. `suites/test\_suite\_mpi.data`). The `function file` contains the test functions. The `data file` contains the test cases, specified as parameters that will be passed to the test function.
+
+For machines with a Unix shell and OpenSSL (and optionally GnuTLS) installed, additional test scripts are available:
+
+-   `tests/ssl-opt.sh` runs integration tests for various TLS options (renegotiation, resumption, etc.) and tests interoperability of these options with other implementations.
+-   `tests/compat.sh` tests interoperability of every ciphersuite with other implementations.
+-   `tests/scripts/test-ref-configs.pl` test builds in various reduced configurations.
+-   `tests/scripts/key-exchanges.pl` test builds in configurations with a single key exchange enabled
+-   `tests/scripts/all.sh` runs a combination of the above tests, plus some more, with various build options (such as ASan, full `config.h`, etc).
+
+Configurations
+--------------
+
+We provide some non-standard configurations focused on specific use cases in the `configs/` directory. You can read more about those in `configs/README.txt`
+
+Porting mbed TLS
+----------------
+
+mbed TLS can be ported to many different architectures, OS's and platforms. Before starting a port, you may find the following knowledge base articles useful:
+
+-   [Porting mbed TLS to a new environment or OS](https://tls.mbed.org/kb/how-to/how-do-i-port-mbed-tls-to-a-new-environment-OS)
+-   [What external dependencies does mbed TLS rely on?](https://tls.mbed.org/kb/development/what-external-dependencies-does-mbedtls-rely-on)
+-   [How do I configure mbed TLS](https://tls.mbed.org/kb/compiling-and-building/how-do-i-configure-mbedtls)
+
+Contributing
+------------
+
+We gratefully accept bug reports and contributions from the community. There are some requirements we need to fulfill in order to be able to integrate contributions:
+
+-   All contributions, whether large or small require a Contributor's License Agreement (CLA) to be accepted. This is because source code can possibly fall under copyright law and we need your consent to share in the ownership of the copyright.
+-   We would ask that contributions conform to [our coding standards](https://tls.mbed.org/kb/development/mbedtls-coding-standards), and that contributions should be fully tested before submission.
+-   As with any open source project, contributions will be reviewed by the project team and community and may need some modifications to be accepted.
+
+To accept the Contributor’s Licence Agreement (CLA), individual contributors can do this by creating an mbed account and [accepting the online agreement here with a click through](https://developer.mbed.org/contributor_agreement/). Alternatively, for contributions from corporations, or those that do not wish to create an mbed account, a slightly different agreement can be found [here](https://www.mbed.com/en/about-mbed/contributor-license-agreements/). This agreement should be signed and returned to ARM as described in the instructions given.
+
+### Making a Contribution
+
+1.  [Check for open issues](https://github.com/ARMmbed/mbedtls/issues) or [start a discussion](https://tls.mbed.org/discussions) around a feature idea or a bug.
+2.  Fork the [mbed TLS repository on GitHub](https://github.com/ARMmbed/mbedtls) to start making your changes. As a general rule, you should use the "development" branch as a basis.
+3.  Write a test which shows that the bug was fixed or that the feature works as expected.
+4.  Send a pull request and bug us until it gets merged and published. Contributions may need some modifications, so work with us to get your change accepted. We will include your name in the ChangeLog :)

+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,

+# Purpose:
+# - To test and prove that a new commit in  the mbed TLS repository builds
+# and integrates with mbed-os properly.
+#           AND
+# - To test and prove that the current development head of mbed TLS builds
+# and integrates with the current mbed-os master branch.
+#
+# The script fetches all the prerequisites and builds the mbed TLS 'tls-client'
+# example. This script is triggered by every commit and once each night and the
+# exact behaviour depends on how it was triggered:
+# - If it is a nightly build then it builds the mbed TLS development head with
+#   mbed-os master.
+# - If it was triggered by the commit, then it builds the example with mbed TLS
+#   at that commit and mbed-os at the commit pointed by mbed-os.lib in the
+#   example repository.

+This directory contains example configuration files.
+
+The examples are generally focused on a particular usage case (eg, support for
+a restricted number of ciphersuites) and aim at minimizing resource usage for
+this target. They can be used as a basis for custom configurations.
+
+These files are complete replacements for the default config.h. To use one of
+them, you can pick one of the following methods:
+
+1. Replace the default file include/mbedtls/config.h with the chosen one.
+   (Depending on your compiler, you may need to ajust the line with
+   #include "mbedtls/check_config.h" then.)
+
+2. Define MBEDTLS_CONFIG_FILE and adjust the include path accordingly.
+   For example, using make:
+
+    CFLAGS="-I$PWD/configs -DMBEDTLS_CONFIG_FILE='<foo.h>'" make
+
+   Or, using cmake:
+
+    find . -iname '*cmake*' -not -name CMakeLists.txt -exec rm -rf {} +
+    CFLAGS="-I$PWD/configs -DMBEDTLS_CONFIG_FILE='<foo.h>'" cmake .
+    make
+
+Note that the second method also works if you want to keep your custom
+configuration file outside the mbed TLS tree.

+/**
+ * @addtogroup encdec_module Encryption/decryption module
+ *
+ * The Encryption/decryption module provides encryption/decryption functions.
+ * One can differentiate between symmetric and asymmetric algorithms; the
+ * symmetric ones are mostly used for message confidentiality and the asymmetric
+ * ones for key exchange and message integrity.
+ * Some symmetric algorithms provide different block cipher modes, mainly
+ * Electronic Code Book (ECB) which is used for short (64-bit) messages and
+ * Cipher Block Chaining (CBC) which provides the structure needed for longer
+ * messages. In addition the Cipher Feedback Mode (CFB-128) stream cipher mode,
+ * Counter mode (CTR) and Galois Counter Mode (GCM) are implemented for
+ * specific algorithms.
+ *
+ * All symmetric encryption algorithms are accessible via the generic cipher layer
+ * (see \c mbedtls_cipher_setup()).
+ *
+ * The asymmetric encryptrion algorithms are accessible via the generic public
+ * key layer (see \c mbedtls_pk_init()).
+ *
+ * The following algorithms are provided:
+ * - Symmetric:
+ *   - AES (see \c mbedtls_aes_crypt_ecb(), \c mbedtls_aes_crypt_cbc(), \c mbedtls_aes_crypt_cfb128() and
+ *     \c mbedtls_aes_crypt_ctr()).
+ *   - ARCFOUR (see \c mbedtls_arc4_crypt()).
+ *   - Blowfish / BF (see \c mbedtls_blowfish_crypt_ecb(), \c mbedtls_blowfish_crypt_cbc(),
+ *     \c mbedtls_blowfish_crypt_cfb64() and \c mbedtls_blowfish_crypt_ctr())
+ *   - Camellia (see \c mbedtls_camellia_crypt_ecb(), \c mbedtls_camellia_crypt_cbc(),
+ *     \c mbedtls_camellia_crypt_cfb128() and \c mbedtls_camellia_crypt_ctr()).
+ *   - DES/3DES (see \c mbedtls_des_crypt_ecb(), \c mbedtls_des_crypt_cbc(), \c mbedtls_des3_crypt_ecb()
+ *     and \c mbedtls_des3_crypt_cbc()).
+ *   - GCM (AES-GCM and CAMELLIA-GCM) (see \c mbedtls_gcm_init())
+ *   - XTEA (see \c mbedtls_xtea_crypt_ecb()).
+ * - Asymmetric:
+ *   - Diffie-Hellman-Merkle (see \c mbedtls_dhm_read_public(), \c mbedtls_dhm_make_public()
+ *     and \c mbedtls_dhm_calc_secret()).
+ *   - RSA (see \c mbedtls_rsa_public() and \c mbedtls_rsa_private()).
+ *   - Elliptic Curves over GF(p) (see \c mbedtls_ecp_point_init()).
+ *   - Elliptic Curve Digital Signature Algorithm (ECDSA) (see \c mbedtls_ecdsa_init()).
+ *   - Elliptic Curve Diffie Hellman (ECDH) (see \c mbedtls_ecdh_init()).
+ *
+ * This module provides encryption/decryption which can be used to provide
+ * secrecy.
+ *
+ * It also provides asymmetric key functions which can be used for
+ * confidentiality, integrity, authentication and non-repudiation.

+/**
+ * @mainpage mbed TLS v2.4.2 source code documentation
+ *
+ * This documentation describes the internal structure of mbed TLS.  It was
+ * automatically generated from specially formatted comment blocks in
+ * mbed TLS's source code using Doxygen.  (See
+ * http://www.stack.nl/~dimitri/doxygen/ for more information on Doxygen)
+ *
+ * mbed TLS has a simple setup: it provides the ingredients for an SSL/TLS
+ * implementation. These ingredients are listed as modules in the
+ * \ref mainpage_modules "Modules section". This "Modules section" introduces
+ * the high-level module concepts used throughout this documentation.\n
+ * Some examples of mbed TLS usage can be found in the \ref mainpage_examples
+ * "Examples section".
+ *
+ * @section mainpage_modules Modules
+ *
+ * mbed TLS supports SSLv3 up to TLSv1.2 communication by providing the
+ * following:
+ * - TCP/IP communication functions: listen, connect, accept, read/write.
+ * - SSL/TLS communication functions: init, handshake, read/write.
+ * - X.509 functions: CRT, CRL and key handling
+ * - Random number generation
+ * - Hashing
+ * - Encryption/decryption
+ *
+ * Above functions are split up neatly into logical interfaces. These can be
+ * used separately to provide any of the above functions or to mix-and-match
+ * into an SSL server/client solution that utilises a X.509 PKI. Examples of
+ * such implementations are amply provided with the source code.
+ *
+ * Note that mbed TLS does not provide a control channel or (multiple) session
+ * handling without additional work from the developer.
+ *
+ * @section mainpage_examples Examples
+ *
+ * Example server setup:
+ *
+ * \b Prerequisites:
+ * - X.509 certificate and private key
+ * - session handling functions
+ *
+ * \b Setup:
+ * - Load your certificate and your private RSA key (X.509 interface)
+ * - Setup the listening TCP socket (TCP/IP interface)
+ * - Accept incoming client connection (TCP/IP interface)
+ * - Initialise as an SSL-server (SSL/TLS interface)
+ *   - Set parameters, e.g. authentication, ciphers, CA-chain, key exchange
+ *   - Set callback functions RNG, IO, session handling
+ * - Perform an SSL-handshake (SSL/TLS interface)
+ * - Read/write data (SSL/TLS interface)
+ * - Close and cleanup (all interfaces)
+ *
+ * Example client setup:
+ *
+ * \b Prerequisites:
+ * - X.509 certificate and private key
+ * - X.509 trusted CA certificates
+ *
+ * \b Setup:
+ * - Load the trusted CA certificates (X.509 interface)
+ * - Load your certificate and your private RSA key (X.509 interface)
+ * - Setup a TCP/IP connection (TCP/IP interface)
+ * - Initialise as an SSL-client (SSL/TLS interface)
+ *   - Set parameters, e.g. authentication mode, ciphers, CA-chain, session
+ *   - Set callback functions RNG, IO
+ * - Perform an SSL-handshake (SSL/TLS interface)
+ * - Verify the server certificate (SSL/TLS interface)
+ * - Write/read data (SSL/TLS interface)
+ * - Close and cleanup (all interfaces)

+ * 2. Montgomery,       y^2 = x^3 + A x^2 + x   mod P   (Curve25519 + draft)

+ * In the case of Short Weierstrass curves, our code requires that N is an odd

+ * In the case of Montgomery curves, we don't store A but (A + 2) / 4 which is
+ * the quantity actually used in the formulas. Also, nbits is not the size of N
+ * but the required size for private keys.
+ *
+ * If modp is NULL, reduction modulo P is done using a generic algorithm.
+ * Otherwise, it must point to a function that takes an mbedtls_mpi in the range
+ * 0..2^(2*pbits)-1 and transforms it in-place in an integer of little more
+ * than pbits, so that the integer may be efficiently brought in the 0..P-1
+ * range by a few additions or substractions. It must return 0 on success and

+# Purpose
+#
+# Comments and uncomments #define lines in the given header file and optionally
+# sets their value or can get the value. This is to provide scripting control of
+# what preprocessor symbols, and therefore what build time configuration flags
+# are set in the 'config.h' file.
+#
+# Usage: config.pl [-f <file> | --file <file>] [-o | --force]
+#                   [set <symbol> <value> | unset <symbol> | get <symbol> |
+#                       full | realfull]

+
+Commands
+    set <symbol> [<value>]  - Uncomments or adds a #define for the <symbol> to
+                              the configuration file, and optionally making it
+                              of <value>.
+                              If the symbol isn't present in the file an error
+                              is returned.
+    unset <symbol>          - Comments out the #define for the given symbol if
+                              present in the configuration file.
+    get <symbol>            - Finds the #define for the given symbol, returning
+                              an exitcode of 0 if the symbol is found, and -1 if
+                              not. The value of the symbol is output if one is
+                              specified in the configuration file.
+    full                    - Uncomments all #define's in the configuration file
+                              excluding some reserved symbols, until the
+                              'Module configuration options' section
+    realfull                - Uncomments all #define's with no exclusions
+
+Options
+    -f | --file <filename>  - The file or file path for the configuration file
+                              to edit. When omitted, the following default is
+                              used:
+                                $config_file
+    -o | --force            - If the symbol isn't present in the configuration
+                              file when setting its value, a #define is
+                              appended to the end of the file.

+# mbed TLS
+
+mbed TLS makes it trivially easy for developers to include cryptographic and SSL/TLS capabilities in their embedded products, with a minimal code footprint. It offers an SSL library with an intuitive API and readable source code.
+
+**Note:** The current release is beta, and implements no secure source of random numbers, weakening its security.
+
+Currently the only supported yotta targets are:
+- `frdm-k64f-gcc`
+- `frdm-k64f-armcc`
+- `x86-linux-native`
+- `x86-osx-native`
+
+## Sample programs
+
+This release includes the following examples:
+
+1. [**Self test:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-selftest) Tests different basic functions in the mbed TLS library.
+
+2. [**Benchmark:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-benchmark) Measures the time taken to perform basic cryptographic functions used in the library.
+
+3. [**Hashing:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-hashing) Demonstrates the various APIs for computing hashes of data (also known as message digests) with SHA-256.
+
+4. [**Authenticated encryption:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-authcrypt) Demonstrates usage of the Cipher API for encrypting and authenticating data with AES-CCM.
+
+These examples are integrated as yotta tests, so that they are built automatically when you build mbed TLS. Each of them comes with complete usage instructions as a Readme file in the repository.
+
+## Performing TLS and DTLS connections
+
+A high-level API for performing TLS and DTLS connections with mbed TLS in mbed OS is provided in a separate yotta module: [mbed-tls-sockets](https://github.com/ARMmbed/mbed-tls-sockets). We recommend this API for TLS and DTLS connections. It is very similar to the API provided by the [sockets](https://github.com/ARMmbed/sockets) module for unencrypted TCP and UDP connections.
+
+The `mbed-tls-sockets` module includes a complete [example TLS client](https://github.com/ARMmbed/mbed-tls-sockets/blob/master/test/tls-client/main.cpp) with [usage instructions](https://github.com/ARMmbed/mbed-tls-sockets/blob/master/test/tls-client/README.md).
+
+## Configuring mbed TLS features
+
+mbed TLS makes it easy to disable any feature during compilation, if that feature isn't required for a particular project. The default configuration enables all modern and widely-used features, which should meet the needs of new projects, and disables all features that are older or less common, to minimize the code footprint.
+
+The list of available compilation flags is available in the fully documented [config.h file](https://github.com/ARMmbed/mbedtls/blob/development/include/mbedtls/config.h).
+
+If you need to adjust those flags, you can provide your own configuration-adjustment file with suitable `#define` and `#undef` statements. These will be included between the default definitions and the sanity checks. Your configuration file should be in your application's include directory, and can be named freely; you just need to let mbed TLS know the file's name. To do that, use yotta's [configuration system](http://docs.yottabuild.org/reference/config.html). The file's name should be in your `config.json` file, under mbedtls, as the key `user-config-file`.
+
+For example, in an application called `myapp`, if you want to enable the EC J-PAKE key exchange and disable the CBC cipher mode, you can create a file named  `mbedtls-config-changes.h` in the `myapp` directory containing the following lines:
+
+    #define MBEDTLS_ECJPAKE_C
+    #define MBEDTLS_KEY_EXCHANGE_ECJPAKE_ENABLED
+
+    #undef MBEDTLS_CIPHER_MODE_CBC
+
+And then create a file named `config.json` at the root of your application with the following contents:
+
+    {
+       "mbedtls": {
+          "user-config-file": "\"myapp/mbedtls-config-changes.h\""
+       }
+    }
+
+Please note: you need to provide the exact name that will be used in the `#include` directive, including the `<>` or quotes around the name.
+
+## Getting mbed TLS from GitHub
+
+Like most components of mbed OS, mbed TLS is developed in the open and its source can be found on GitHub: [ARMmbed/mbedtls](https://github.com/ARMmbed/mbedtls). Unlike most other mbed OS components, however, you cannot just clone the repository and run `yotta build` from its root. This is because mbed TLS also exists as an independent component, so its repository includes things that are not relevant for mbed OS, as well as other build systems.
+
+The way to use mbed TLS from a clone of the GitHub repository is to run the following commands from the root of a checkout:
+
+    yotta/create-module.sh
+    cd yotta/module
+
+You can then run any yotta command you would normally run, such as `yotta build` or `yotta link`.
+
+## Differences between the standalone and mbed OS editions
+
+While the two editions share the same code base, there are still a number of differences, mainly in configuration and integration. You should keep in mind those differences when reading some articles in our [knowledge base](https://tls.mbed.org/kb), as currently all the articles are about the standalone edition.
+
+* The mbed OS edition has a smaller set of features enabled by default in `config.h`, in order to reduce footprint. While the default configuration of the standalone edition puts more emphasize on maintaining interoperability with old peers, the mbed OS edition only enables the most modern ciphers and the latest version of (D)TLS.
+
+* The following components of mbed TLS are disabled in the mbed OS edition: `net_sockets.c` and `timing.c`. This is because mbed OS include their equivalents.
+
+* The mbed OS edition comes with a fully integrated API for (D)TLS connections in a companion module: [mbed-tls-sockets](https://github.com/ARMmbed/mbed-tls-sockets). See "Performing TLS and DTLS connections" above.
+
+## Other resources
+
+The [mbed TLS website](https://tls.mbed.org) contains many other useful
+resources for the developer, such as [developer
+documentation](https://tls.mbed.org/dev-corner), [knowledgebase
+articles](https://tls.mbed.org/kb), and a [support forum](https://tls.mbed.org/discussions).
+
+## Contributing
+
+We gratefully accept bug reports and contributions from the community. There are some requirements we need to fulfill in order to be able to integrate contributions:
+
+* Simple bug fixes to existing code do not contain copyright themselves and we can integrate without issue. The same is true of trivial contributions.
+
+* For larger contributions, such as a new feature, the code can possibly fall under copyright law. We then need your consent to share in the ownership of the copyright. We have a form for this, which we will send to you in case you submit a contribution or pull request that we deem this necessary for.
+
+To contribute, please:
+
+* [Check for open issues](https://github.com/ARMmbed/mbedtls/issues) or [start a discussion](https://tls.mbed.org/discussions) around a feature idea or a bug.
+
+* Fork the [mbed TLS repository on GitHub](https://github.com/ARMmbed/mbedtls) to start making your changes. As a general rule, you should use the "development" branch as a basis.
+
+* Write a test that shows that the bug was fixed or that the feature works as expected.
+
+* Send a pull request and bug us until it gets merged and published. We will include your name in the ChangeLog.

+# Authenticated Encryption Example
+
+This application performs authenticated encryption and authenticated decryption of a buffer. It serves as a tutorial for the basic authenticated encryption functions of mbed TLS.
+
+## Pre-requisites
+
+To build and run this example you must have:
+
+* A computer with the following software installed:
+  * [CMake](http://www.cmake.org/download/).
+  * [yotta](https://github.com/ARMmbed/yotta). Please note that **yotta has its own set of dependencies**, listed in the [installation instructions](http://armmbed.github.io/yotta/#installing-on-windows).
+  * [Python](https://www.python.org/downloads/).
+  * [The ARM GCC toolchain](https://launchpad.net/gcc-arm-embedded).
+  * A serial terminal emulator (Like screen, pySerial and cu).
+* An [FRDM-K64F](http://developer.mbed.org/platforms/FRDM-K64F/) development board, or another board supported by mbed OS (in which case you'll have to substitute frdm-k64f-gcc with the appropriate target in the instructions below).
+* A micro-USB cable.
+* If your OS is Windows, please follow the installation instructions [for the serial port driver](https://developer.mbed.org/handbook/Windows-serial-configuration).
+
+## Getting started
+
+1. Connect the FRDM-K64F to the computer with the micro-USB cable, being careful to use the "OpenSDA" connector on the target board.
+
+2. Navigate to the mbedtls directory supplied with your release and open a terminal.
+
+3. Set the yotta target:
+
+    ```
+    yotta target frdm-k64f-gcc
+    ```
+
+4. Build mbedtls and the examples. This may take a long time if this is your first compilation:
+
+    ```
+    $ yotta build
+    ```
+
+5. Copy `build/frdm-k64f-gcc/test/mbedtls-test-example-authcrypt.bin` to your mbed board and wait until the LED next to the USB port stops blinking.
+
+6. Start the serial terminal emulator and connect to the virtual serial port presented by FRDM-K64F. 
+
+	Use the following settings:
+
+	* 115200 baud (not 9600).
+	* 8N1.
+	* No flow control. 
+
+7. Press the Reset button on the board.
+
+8. The output in the terminal window should look like:
+
+    ```
+    {{timeout;10}}
+    {{host_test_name;default}}
+    {{description;mbed TLS example authcrypt}}
+    {{test_id;MBEDTLS_EX_AUTHCRYPT}}
+    {{start}}
+
+
+    plaintext message: 536f6d65207468696e67732061726520626574746572206c65667420756e7265616400
+    ciphertext: c57f7afb94f14c7977d785d08682a2596bd62ee9dcf216b8cccd997afee9b402f5de1739e8e6467aa363749ef39392e5c66622b01c7203ec0a3d14
+    decrypted: 536f6d65207468696e67732061726520626574746572206c65667420756e7265616400
+
+    DONE
+    {{success}}
+    {{end}}
+    ```
+
+The actual output for the ciphertext line will vary on each run because of the use of a random nonce in the encryption process.

+# mbed TLS Benchmark Example
+
+This application benchmarks the various cryptographic primitives offered by mbed TLS.
+
+## Pre-requisites
+
+To build and run this example you must have:
+
+* A computer with the following software installed:
+  * [CMake](http://www.cmake.org/download/).
+  * [yotta](https://github.com/ARMmbed/yotta). Please note that **yotta has its own set of dependencies**, listed in the [installation instructions](http://armmbed.github.io/yotta/#installing-on-windows).
+  * [Python](https://www.python.org/downloads/).
+  * [The ARM GCC toolchain](https://launchpad.net/gcc-arm-embedded).
+  * A serial terminal emulator (Like screen, pySerial and cu).
+* An [FRDM-K64F](http://developer.mbed.org/platforms/FRDM-K64F/) development board, or another board supported by mbed OS (in which case you'll have to substitute frdm-k64f-gcc with the appropriate target in the instructions below).
+* A micro-USB cable.
+* If your OS is Windows, please follow the installation instructions [for the serial port driver](https://developer.mbed.org/handbook/Windows-serial-configuration).
+
+## Getting started
+
+1. Connect the FRDM-K64F to the computer with the micro-USB cable, being careful to use the "OpenSDA" connector on the target board.
+
+2. Navigate to the mbedtls directory supplied with your release and open a terminal.
+
+3. Set the yotta target:
+
+    ```
+    yotta target frdm-k64f-gcc
+    ```
+
+4. Build mbedtls and the examples. This may take a long time if this is your first compilation:
+
+    ```
+    $ yotta build
+    ```
+
+5. Copy `build/frdm-k64f-gcc/test/mbedtls-test-example-benchmark.bin` to your mbed board and wait until the LED next to the USB port stops blinking.
+
+6. Start the serial terminal emulator and connect to the virtual serial port presented by FRDM-K64F. 
+
+	Use the following settings:
+
+	* 115200 baud (not 9600).
+	* 8N1.
+	* No flow control. 
+
+7. Press the Reset button on the board.
+
+8. The output in the terminal window should look like:
+
+    ```

+
+Any performance data generated by this example application are indicative only of the performance of the mbed TLS module on the platform it's executed on.
+
+Differences in the integration of mbed TLS into the platform, such as whether all available hardware accelerators have been used or not, can lead to significant differences in performance, and so results from the program are not intended to be used to meaningfully compare platforms.
+
+The figures may also slightly change from execution to execution due to variations in the timing functions.

+# SHA-256 Hash Example
+
+This application performs hashing of a buffer with SHA-256 using various APIs. It serves as a tutorial for the basic hashing APIs of mbed TLS.
+
+## Pre-requisites
+
+To build and run this example you must have:
+
+* A computer with the following software installed:
+  * [CMake](http://www.cmake.org/download/).
+  * [yotta](https://github.com/ARMmbed/yotta). Please note that **yotta has its own set of dependencies**, listed in the [installation instructions](http://armmbed.github.io/yotta/#installing-on-windows).
+  * [Python](https://www.python.org/downloads/).
+  * [The ARM GCC toolchain](https://launchpad.net/gcc-arm-embedded).
+  * A serial terminal emulator (Like screen, pySerial and cu).
+* An [FRDM-K64F](http://developer.mbed.org/platforms/FRDM-K64F/) development board, or another board supported by mbed OS (in which case you'll have to substitute frdm-k64f-gcc with the appropriate target in the instructions below).
+* A micro-USB cable.
+* If your OS is Windows, please follow the installation instructions [for the serial port driver](https://developer.mbed.org/handbook/Windows-serial-configuration).
+
+## Getting started
+
+1. Connect the FRDM-K64F to the computer with the micro-USB cable, being careful to use the "OpenSDA" connector on the target board.
+
+2. Navigate to the mbedtls directory supplied with your release and open a terminal.
+
+3. Set the yotta target:
+
+    ```
+    yotta target frdm-k64f-gcc
+    ```
+
+4. Build mbedtls and the examples. This may take a long time if this is your first compilation:
+
+    ```
+    $ yotta build
+    ```
+
+5. Copy `build/frdm-k64f-gcc/test/mbedtls-test-example-hashing.bin` to your mbed board and wait until the LED next to the USB port stops blinking.
+
+6. Start the serial terminal emulator and connect to the virtual serial port presented by FRDM-K64F. 
+
+	Use the following settings:
+
+	* 115200 baud (not 9600).
+	* 8N1.
+	* No flow control. 
+
+7. Press the Reset button on the board.
+
+8. The output in the terminal window should look like:
+
+    ```

+// Options
+
+// Each of the definitions above may have "options" attached.  These are
+// just annotations which may cause code to be generated slightly differently
+// or may contain hints for code that manipulates protocol messages.
+//
+// Clients may define custom options as extensions of the *Options messages.
+// These extensions may not yet be known at parsing time, so the parser cannot
+// store the values in them.  Instead it stores them in a field in the *Options
+// message called uninterpreted_option. This field must have the same name
+// across all *Options messages. We then use this field to populate the
+// extensions when we build a descriptor, at which point all protos have been
+// parsed and so all extensions are known.
+//
+// Extension numbers for custom options may be chosen as follows:
+// * For options which will only be used within a single application or
+//   organization, or for experimental options, use field numbers 50000
+//   through 99999.  It is up to you to ensure that you do not use the
+//   same number for multiple options.
+// * For options which will be published and used publicly by multiple
+//   independent entities, e-mail protobuf-global-extension-registry@google.com
+//   to reserve extension numbers. Simply provide your project name (e.g.
+//   Object-C plugin) and your porject website (if available) -- there's no need
+//   to explain how you intend to use them. Usually you only need one extension
+//   number. You can declare multiple options with only one extension number by
+//   putting them in a sub-message. See the Custom Options section of the docs
+//   for examples:
+//   https://developers.google.com/protocol-buffers/docs/proto#options
+//   If this turns out to be popular, a web service will be set up
+//   to automatically assign option numbers.

+  //   the block.

+  //   does not mean that it is a descendent.  For example, a "group" defines
+  //   both a type and a field in a single declaration.  Thus, the locations
+  //   corresponding to the type and field and their components will overlap.

+@brief This function generates DH domain parameters in Galois prime field according to standard [ANS X9.42].
+It receives the required sizes (in bits) of the modulus, the generator's order, and the seed, and then generates
+the prime modulus and the generator according to given sizes.
+If generateSeed argument is set to 1, the function generates and outputs the random seed. Otherwise (if set to 0),
+the seed has to be passed as an input argument. According to implementation the seed should be not greate, than (2^seedSizeBits - 2^32).
+The seed and some additional parameters, generated by the function (factorJ, pgenCounter), are used for checking
+that all domain parameters are generated according to the standard and not forged.
+\note All buffer parameters should be in Big-Endian form.
+
+@return CRYS_OK on success.
+@return A non-zero value on failure as defined crys_dh_error.h, crys_rnd_error.h or crys_hash_error.h.

+@brief This file contains all of the enums and definitions
+that are used for the CRYS HASH APIs, as well as the APIs themselves.
+@defgroup crys_hash CryptoCell HASH APIs
+@{
+@ingroup cryptocell_api
+
+
+This product supports the following HASH algorithms (or modes, according to product):
+<ul><li> CRYS_HASH_MD5 (producing 16 byte output).</li>
+<li> CRYS_HASH_SHA1 (producing 20 byte output).</li>
+<li> CRYS_HASH_SHA224 (producing 28 byte output).</li>
+<li> CRYS_HASH_SHA256 (producing 32 byte output).</li>
+<li> CRYS_HASH_SHA384 (producing 48 byte output).</li>
+<li> CRYS_HASH_SHA512 (producing 64 byte output).</li></ul>
+
+HASH calculation can be performed in either of the following two modes of operation:
+<ul><li> Integrated operation - Processes all data in a single function call. This flow is applicable when all data is available prior to the
+     cryptographic operation.</li>
+<li> Block operation - Processes a subset of the data buffers, and is called multiple times in a sequence. This flow is applicable when the
+     next data buffer becomes available only during/after processing of the current data buffer.</li></ul>
+
+The following is a typical HASH Block operation flow:
+<ol><li> ::CRYS_HASH_Init - this function initializes the HASH machine on the CRYS level by setting the context pointer that is used on the entire
+     HASH operation.</li>
+<li> ::CRYS_HASH_Update - this function runs a HASH operation on a block of data allocated by the user. This function may be called as many times
+     as required.</li>
+<li> ::CRYS_HASH_Finish - this function ends the HASH operation. It returns the digest result and clears the context.</li></ol>

+
+
+HMAC is a wrapping algorithm that uses a HASH function (one of the supported HASH algorithms, as specified in the HASH chapter) and a key,
+to generate a unique authentication code over the input data.
+HMAC calculation can be performed in either of the following two modes of operation:
+<ul><li> Integrated operation - Processes all data in a single function call. This flow is applicable when all data is available prior to
+the cryptographic operation.</li>
+<li> Block operation - Processes a subset of the data buffers, and is called multiple times in a sequence. This flow is applicable when
+the next data buffer becomes available only during/after processing of the current data buffer.</li></ul>
+
+The following is a typical HMAC Block operation flow:
+<ol><li> ::CRYS_HMAC_Init: This function initializes the HMAC machine on the CRYS level by setting the context pointer that is
+    used on the entire HMAC operation.</li>
+<li> ::CRYS_HMAC_Update: This function runs an HMAC operation on a block of data allocated by the user. This function may be called as
+     many times as required.</li>
+<li> ::CRYS_HMAC_Finish: This function ends the HMAC operation. It returns the digest result and clears the context.</li></ol>

+
+The input data may be either a non-hashed data or a digest of a hash function.
+For a non-hashed data, the input data will be hashed using the hash function indicated by ::CRYS_RSA_HASH_OpMode_t.
+For a digest, ::CRYS_RSA_HASH_OpMode_t should indicate the hash function that the input data was created by, and it will not be hashed.
+
+@return CRYS_OK on success.
+@return A non-zero value from crys_rsa_error.h or crys_hash_error.h on failure.

+/**@file
+ * SRP is an augmented password-authenticated key agreement protocol,
+ * specifically designed to work around existing patents. SRP allows the use of
+ * user names and passwords over unencrypted channels and supplies a shared
+ * secret at the end of the authentication sequence that can be used to generate
+ * encryption keys.
+ *
+ * An eavesdropper or man in the middle cannot obtain enough information to be
+ * able to brute force guess a password without further interactions with the
+ * parties for each guess.
+ *
+ * The server does not store password-equivalent data. This means that an
+ * attacker who steals the server data cannot masquerade as the client unless
+ * they first perform a brute force search for the password.
+ *
+ * The specific variant implemented here is SRP-6 3072 bit SHA-512 as mandated
+ * by Apple for use with HomeKit.
+ *
+ * @see [RFC 5054 - Using the Secure Remote Password (SRP) Protocol for TLS Authentication](https://tools.ietf.org/html/rfc5054)
+ * @see [The Stanford SRP Homepage](http://srp.stanford.edu)
+ *
+ * **Basic protocol overview**
+ *
+ * *Setup*
+ * 1. Server generates a username / password combination together with a salt.
+ * 2. Server derives a password verifier (see #occ_srp_verifier).
+ * 3. The username, salt and verifier are stored and required to open sessions.
+ *    The original password is no longer needed.
+ *
+ * *Session opening*
+ * 1. Client sends a username and the public key of an ephemeral key pair to the
+ *    server.
+ * 2. Server sends the salt and the public key of another ephemeral key pair to
+ *    the client (see #occ_srp_public_key).
+ * 3. Client and Server both compute the session key from this information (see
+ *    #occ_srp_scrambling_parameter, #occ_srp_premaster_secret,
+ *    #occ_srp_session_key).
+ * 4. Client sends proof of the session key to the server.
+ * 5. Server validates proof (see #occ_srp_proof_m1), then sends proof of the 
+ *    session key to the client (see #occ_srp_proof_m2).
+ * 6. Client validates proof. Both parties know that they share the same private
+ *    session key.

+ * Example: In case you uncomment MBEDTLS_SHA256_PROCESS_ALT, mbed TLS will

+ * the other function (using your mbedtls_sha1_process() function) and the definition

+ * with this definition.
+ *
+ * Note: if you use the AES_xxx_ALT macros, then is is recommended to also set
+ * MBEDTLS_AES_ROM_TABLES in order to help the linker garbage-collect the AES
+ * tables.

+Protothreads are extremely lightweight stackless threads designed for
+severely memory constrained systems such as small embedded systems or
+sensor network nodes. Protothreads can be used with or without an
+underlying operating system.
+
+Protothreads provides a blocking context on top of an event-driven
+system, without the overhead of per-thread stacks. The purpose of
+protothreads is to implement sequential flow of control without
+complex state machines or full multi-threading.
+
+Main features:
+
+    * No machine specific code - the protothreads library is pure C
+    * Does not use error-prone functions such as longjmp()
+    * Very small RAM overhead - only two bytes per protothread
+    * Can be used with or without an OS
+    * Provides blocking wait without full multi-threading or
+      stack-switching
+    * Freely available under a BSD-like open source license    
+
+Example applications:
+
+    * Memory constrained systems
+    * Event-driven protocol stacks
+    * Small embedded systems
+    * Sensor network nodes
+
+The protothreads library is released under an open source BSD-style
+license that allows for both non-commercial and commercial usage. The
+only requirement is that credit is given.
+
+The protothreads library was written by Adam Dunkels <adam@sics.se>
+with support from Oliver Schmidt <ol.sc@web.de>.
+
+More information and new versions can be found at the protothreads
+homepage:
+		     http://www.sics.se/~adam/pt/
+
+Documentation can be found in the doc/ subdirectory.
+
+Two example programs illustrating the use of protothreads can be found
+in this directory:
+
+   example-small.c         A small example showing how to use protothreads
+   example-buffer.c        The bounded buffer problem with protothreads
+   example-codelock.c	   A code lock with simulated key input
+
+To compile the examples, simply run "make".

+Implementation of local continuations based on switch() statment. 
+<p>
+<dl compact><dt><b>Author:</b></dt><dd>Adam Dunkels &lt;<a href="mailto:adam@sics.se">adam@sics.se</a>&gt;</dd></dl>
+This implementation of local continuations uses the C switch() statement to resume execution of a function somewhere inside the function's body. The implementation is based on the fact that switch() statements are able to jump directly into the bodies of control structures such as if() or while() statmenets.<p>
+This implementation borrows heavily from Simon Tatham's coroutines implementation in C: <a href="http://www.chiark.greenend.org.uk/~sgtatham/coroutines.html">http://www.chiark.greenend.org.uk/~sgtatham/coroutines.html</a>

+A code-lock</a></h2>
+This example shows how to implement a simple code lock - the kind of device that is placed next to doors and that you have to push a four digit number into in order to unlock the door.<p>
+The code lock waits for key presses from a numeric keyboard and if the correct code is entered, the lock is unlocked. There is a maximum time of one second between each key press, and after the correct code has been entered, no more keys must be pressed for 0.5 seconds before the lock is opened.<p>

+The bounded buffer with protothread semaphores</a></h2>
+The following example shows how to implement the bounded buffer problem using the protothreads semaphore library. The example uses three protothreads: one producer() protothread that produces items, one consumer() protothread that consumes items, and one driver_thread() that schedules the producer and consumer protothreads.<p>
+Note that there is no need for a mutex to guard the add_to_buffer() and get_from_buffer() functions because of the implicit locking semantics of protothreads - a protothread will never be preempted and will never block except in an explicit PT_WAIT statement.<p>

+</h1><hr><a name="_details"></a><h2>Detailed Description</h2>
+This module implements counting semaphores on top of protothreads. 
+<p>
+Semaphores are a synchronization primitive that provide two operations: "wait" and "signal". The "wait" operation checks the semaphore counter and blocks the thread if the counter is zero. The "signal" operation increases the semaphore counter but does not block. If another thread has blocked waiting for the semaphore that is signalled, the blocked thread will become runnable again.<p>
+Semaphores can be used to implement other, more structured, synchronization primitives such as monitors and message queues/bounded buffers (see below).<p>
+The following example shows how the producer-consumer problem, also known as the bounded buffer problem, can be solved using protothreads and semaphores. Notes on the program follow after the example.<p>

+The program uses three protothreads: one protothread that implements the consumer, one thread that implements the producer, and one protothread that drives the two other protothreads. The program uses three semaphores: "full", "empty" and "mutex". The "mutex" semaphore is used to provide mutual exclusion for the buffer, the "empty" semaphore is used to block the consumer is the buffer is empty, and the "full" semaphore is used to block the producer is the buffer is full.<p>
+The "driver_thread" holds two protothread state variables, "pt_producer" and "pt_consumer". It is important to note that both these variables are declared as <em>static</em>. If the static keyword is not used, both variables are stored on the stack. Since protothreads do not store the stack, these variables may be overwritten during a protothread wait operation. Similarly, both the "consumer" and "producer" protothreads declare their local variables as static, to avoid them being stored on the stack.

+Local continuations form the basis for implementing protothreads. 
+<p>
+A local continuation can be <em>set</em> in a specific function to capture the state of the function. After a local continuation has been set can be <em>resumed</em> in order to restore the state of the function at the point where the local continuation was set.

+Protothreads are a type of lightweight stackless threads designed for severly memory constrained systems such as deeply embedded systems or sensor network nodes. Protothreads provides linear code execution for event-driven systems implemented in C. Protothreads can be used with or without an RTOS.<p>
+Protothreads are a extremely lightweight, stackless type of threads that provides a blocking context on top of an event-driven system, without the overhead of per-thread stacks. The purpose of protothreads is to implement sequential flow of control without complex state machines or full multi-threading. Protothreads provides conditional blocking inside C functions.<p>
+Main features:<p>
+<ul>
+<li>No machine specific code - the protothreads library is pure C</li></ul>
+<p>
+<ul>
+<li>Does not use error-prone functions such as longjmp()</li></ul>
+<p>
+<ul>
+<li>Very small RAM overhead - only two bytes per protothread</li></ul>
+<p>
+<ul>
+<li>Can be used with or without an OS</li></ul>
+<p>
+<ul>
+<li>Provides blocking wait without full multi-threading or stack-switching</li></ul>

+The protothreads library was written by Adam Dunkels &lt;<a href="mailto:adam@sics.se">adam@sics.se</a>&gt; with support from Oliver Schmidt &lt;<a href="mailto:ol.sc@web.de">ol.sc@web.de</a>&gt;.<h2><a class="anchor" name="using">
+Using protothreads</a></h2>
+Using protothreads in a project is easy: simply copy the files <a class="el" href="a00013.html">pt.h</a>, <a class="el" href="a00011.html">lc.h</a> and lc-switch.h into the include files directory of the project, and #include "pt.h" in all files that should use protothreads.<h2><a class="anchor" name="pt-desc">
+Protothreads</a></h2>
+Protothreads are a extremely lightweight, stackless threads that provides a blocking context on top of an event-driven system, without the overhead of per-thread stacks. The purpose of protothreads is to implement sequential flow of control without using complex state machines or full multi-threading. Protothreads provides conditional blocking inside a C function.<p>
+In memory constrained systems, such as deeply embedded systems, traditional multi-threading may have a too large memory overhead. In traditional multi-threading, each thread requires its own stack, that typically is over-provisioned. The stacks may use large parts of the available memory.<p>
+The main advantage of protothreads over ordinary threads is that protothreads are very lightweight: a protothread does not require its own stack. Rather, all protothreads run on the same stack and context switching is done by stack rewinding. This is advantageous in memory constrained systems, where a stack for a thread might use a large part of the available memory. A protothread only requires only two bytes of memory per protothread. Moreover, protothreads are implemented in pure C and do not require any machine-specific assembler code.<p>
+A protothread runs within a single C function and cannot span over other functions. A protothread may call normal C functions, but cannot block inside a called function. Blocking inside nested function calls is instead made by spawning a separate protothread for each potentially blocking function. The advantage of this approach is that blocking is explicit: the programmer knows exactly which functions that block that which functions the never blocks.<p>
+Protothreads are similar to asymmetric co-routines. The main difference is that co-routines uses a separate stack for each co-routine, whereas protothreads are stackless. The most similar mechanism to protothreads are Python generators. These are also stackless constructs, but have a different purpose. Protothreads provides blocking contexts inside a C function, whereas Python generators provide multiple exit points from a generator function.<h2><a class="anchor" name="pt-autovars">
+Local variables</a></h2>
+<dl compact><dt><b>Note:</b></dt><dd>Because protothreads do not save the stack context across a blocking call, local variables are not preserved when the protothread blocks. This means that local variables should be used with utmost care - if in doubt, do not use local variables inside a protothread!</dd></dl>
+<h2><a class="anchor" name="pt-scheduling">
+Scheduling</a></h2>
+A protothread is driven by repeated calls to the function in which the protothread is running. Each time the function is called, the protothread will run until it blocks or exits. Thus the scheduling of protothreads is done by the application that uses protothreads.<h2><a class="anchor" name="pt-impl">
+Implementation</a></h2>
+Protothreads are implemented using local continuations. A local continuation represents the current state of execution at a particular place in the program, but does not provide any call history or local variables. A local continuation can be set in a specific function to capture the state of the function. After a local continuation has been set can be resumed in order to restore the state of the function at the point where the local continuation was set.<p>
+Local continuations can be implemented in a variety of ways:<p>
+<ol type=1>
+<li>by using machine specific assembler code,</li><li>by using standard C constructs, or</li><li>by using compiler extensions.</li></ol>
+<p>
+The first way works by saving and restoring the processor state, except for stack pointers, and requires between 16 and 32 bytes of memory per protothread. The exact amount of memory required depends on the architecture.<p>
+The standard C implementation requires only two bytes of state per protothread and utilizes the C switch() statement in a non-obvious way that is similar to Duff's device. This implementation does, however, impose a slight restriction to the code that uses protothreads: a protothread cannot perform a blocking wait (<a class="el" href="a00014.html#g99e43010ec61327164466aa2d902de45">PT_WAIT_UNTIL()</a> or <a class="el" href="a00014.html#g155cba6121323726d02c00284428fed6">PT_YIELD()</a>) inside a switch() statement.<p>
+Certain compilers has C extensions that can be used to implement protothreads. GCC supports label pointers that can be used for this purpose. With this implementation, protothreads require 4 bytes of RAM per protothread. <hr size="1"><address style="align: right;"><small>Generated on Mon Oct 2 10:06:29 2006 for The Protothreads Library 1.4 by&nbsp;

+
+Protothreads are a type of lightweight stackless threads designed for
+severly memory constrained systems such as deeply embedded systems or
+sensor network nodes. Protothreads provides linear code execution for
+event-driven systems implemented in C. Protothreads can be used with
+or without an RTOS.
+
+Protothreads are a extremely lightweight, stackless type of threads
+that provides a blocking context on top of an event-driven system,
+without the overhead of per-thread stacks. The purpose of protothreads
+is to implement sequential flow of control without complex state
+machines or full multi-threading. Protothreads provides conditional
+blocking inside C functions.
+
+Main features:
+
+    - No machine specific code - the protothreads library is pure C
+
+    - Does not use error-prone functions such as longjmp()
+        
+    - Very small RAM overhead - only two bytes per protothread
+    
+    - Can be used with or without an OS
+    
+    - Provides blocking wait without full multi-threading or
+      stack-switching
+
+Examples applications:
+
+    - Memory constrained systems
+    
+    - Event-driven protocol stacks
+    
+    - Deeply embedded systems
+    
+    - Sensor network nodes

+\section authors Authors
+
+The protothreads library was written by Adam Dunkels <adam@sics.se>
+with support from Oliver Schmidt <ol.sc@web.de>.
+
+\section using Using protothreads
+
+Using protothreads in a project is easy: simply copy the files pt.h,
+lc.h and lc-switch.h into the include files directory of the project,
+and \#include "pt.h" in all files that should use protothreads.
+
+\section pt-desc Protothreads
+
+Protothreads are a extremely lightweight, stackless threads that
+provides a blocking context on top of an event-driven system, without
+the overhead of per-thread stacks. The purpose of protothreads is to
+implement sequential flow of control without using complex state
+machines or full multi-threading. Protothreads provides conditional
+blocking inside a C function.
+
+In memory constrained systems, such as deeply embedded systems,
+traditional multi-threading may have a too large memory overhead. In
+traditional multi-threading, each thread requires its own stack, that
+typically is over-provisioned. The stacks may use large parts of the
+available memory.
+
+The main advantage of protothreads over ordinary threads is that
+protothreads are very lightweight: a protothread does not require its
+own stack. Rather, all protothreads run on the same stack and context
+switching is done by stack rewinding. This is advantageous in memory
+constrained systems, where a stack for a thread might use a large part
+of the available memory. A protothread only requires only two bytes of
+memory per protothread. Moreover, protothreads are implemented in pure
+C and do not require any machine-specific assembler code.
+
+A protothread runs within a single C function and cannot span over
+other functions. A protothread may call normal C functions, but cannot
+block inside a called function. Blocking inside nested function calls
+is instead made by spawning a separate protothread for each
+potentially blocking function. The advantage of this approach is that
+blocking is explicit: the programmer knows exactly which functions
+that block that which functions the never blocks.
+
+Protothreads are similar to asymmetric co-routines. The main
+difference is that co-routines uses a separate stack for each
+co-routine, whereas protothreads are stackless. The most similar
+mechanism to protothreads are Python generators. These are also
+stackless constructs, but have a different purpose. Protothreads
+provides blocking contexts inside a C function, whereas Python
+generators provide multiple exit points from a generator function.
+
+\section pt-autovars Local variables
+
+\note 
+Because protothreads do not save the stack context across a blocking
+call, local variables are not preserved when the protothread
+blocks. This means that local variables should be used with utmost
+care - if in doubt, do not use local variables inside a protothread!
+
+\section pt-scheduling Scheduling
+
+A protothread is driven by repeated calls to the function in which the
+protothread is running. Each time the function is called, the
+protothread will run until it blocks or exits. Thus the scheduling of
+protothreads is done by the application that uses protothreads.
+
+\section pt-impl Implementation
+
+Protothreads are implemented using local continuations. A local
+continuation represents the current state of execution at a particular
+place in the program, but does not provide any call history or local
+variables. A local continuation can be set in a specific function to
+capture the state of the function. After a local continuation has been
+set can be resumed in order to restore the state of the function at
+the point where the local continuation was set.
+
+
+Local continuations can be implemented in a variety of ways:
+
+   -# by using machine specific assembler code,
+   -# by using standard C constructs, or
+   -# by using compiler extensions. 
+
+The first way works by saving and restoring the processor state,
+except for stack pointers, and requires between 16 and 32 bytes of
+memory per protothread. The exact amount of memory required depends on
+the architecture.
+
+The standard C implementation requires only two bytes of state per
+protothread and utilizes the C switch() statement in a non-obvious way
+that is similar to Duff's device. This implementation does, however,
+impose a slight restriction to the code that uses protothreads: a
+protothread cannot perform a blocking wait (PT_WAIT_UNTIL() or
+PT_YIELD()) inside a switch() statement.
+
+Certain compilers has C extensions that can be used to implement
+protothreads. GCC supports label pointers that can be used for this
+purpose. With this implementation, protothreads require 4 bytes of RAM
+per protothread.

+ * \defgroup ptsem Protothread semaphores
+ * @{
+ *
+ * This module implements counting semaphores on top of
+ * protothreads. Semaphores are a synchronization primitive that
+ * provide two operations: "wait" and "signal". The "wait" operation
+ * checks the semaphore counter and blocks the thread if the counter
+ * is zero. The "signal" operation increases the semaphore counter but
+ * does not block. If another thread has blocked waiting for the
+ * semaphore that is signalled, the blocked thread will become
+ * runnable again.
+ *
+ * Semaphores can be used to implement other, more structured,
+ * synchronization primitives such as monitors and message
+ * queues/bounded buffers (see below).
+ *
+ * The following example shows how the producer-consumer problem, also
+ * known as the bounded buffer problem, can be solved using
+ * protothreads and semaphores. Notes on the program follow after the
+ * example.

+ * The program uses three protothreads: one protothread that
+ * implements the consumer, one thread that implements the producer,
+ * and one protothread that drives the two other protothreads. The
+ * program uses three semaphores: "full", "empty" and "mutex". The
+ * "mutex" semaphore is used to provide mutual exclusion for the
+ * buffer, the "empty" semaphore is used to block the consumer is the
+ * buffer is empty, and the "full" semaphore is used to block the
+ * producer is the buffer is full.
+ *
+ * The "driver_thread" holds two protothread state variables,
+ * "pt_producer" and "pt_consumer". It is important to note that both
+ * these variables are declared as <i>static</i>. If the static
+ * keyword is not used, both variables are stored on the stack. Since
+ * protothreads do not store the stack, these variables may be
+ * overwritten during a protothread wait operation. Similarly, both
+ * the "consumer" and "producer" protothreads declare their local
+ * variables as static, to avoid them being stored on the stack.

+File    : SEGGER_RTT.c
+Purpose : Implementation of SEGGER real-time transfer (RTT) which
+          allows real-time communication on targets which support
+          debugger memory accesses while the CPU is running.
+Revision: $Rev: 6852 $
+
+Additional information:
+          Type "int" is assumed to be 32-bits in size
+          H->T    Host to target communication
+          T->H    Target to host communication
+
+          RTT channel 0 is always present and reserved for Terminal usage.
+          Name is fixed to "Terminal"
+
+          Effective buffer size: SizeOfBuffer - 1
+
+          WrOff == RdOff:       Buffer is empty
+          WrOff == (RdOff - 1): Buffer is full
+          WrOff >  RdOff:       Free space includes wrap-around
+          WrOff <  RdOff:       Used space includes wrap-around
+          (WrOff == (SizeOfBuffer - 1)) && (RdOff == 0):  
+                                Buffer full and wrap-around after next byte

+SIL OPEN FONT LICENSE
+
+Version 1.1 - 26 February 2007
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this license and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as
+distributed by the Copyright Holder(s).
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting — in part or in whole — any of the components of the
+Original Version, by changing formats or by porting the Font Software to a
+new environment.
+
+"Author" refers to any designer, engineer, programmer, technical
+writer or other person who contributed to the Font Software.
+
+PERMISSION & CONDITIONS
+Permission is hereby granted, free of charge, to any person obtaining
+a copy of the Font Software, to use, study, copy, merge, embed, modify,
+redistribute, and sell modified and unmodified copies of the Font
+Software, subject to the following conditions:
+
+1) Neither the Font Software nor any of its individual components,
+in Original or Modified Versions, may be sold by itself.
+
+2) Original or Modified Versions of the Font Software may be bundled,
+redistributed and/or sold with any software, provided that each copy
+contains the above copyright notice and this license. These can be
+included either as stand-alone text files, human-readable headers or
+in the appropriate machine-readable metadata fields within text or
+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding
+Copyright Holder. This restriction only applies to the primary font name as
+presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+Software shall not be used to promote, endorse or advertise any
+Modified Version, except to acknowledge the contribution(s) of the
+Copyright Holder(s) and the Author(s) or with their explicit written
+permission.
+
+5) The Font Software, modified or unmodified, in part or in whole,
+must be distributed entirely under this license, and must not be
+distributed under any other license. The requirement for fonts to
+remain under this license does not apply to any document created
+using the Font Software.
+
+TERMINATION
+This license becomes null and void if any of the above conditions are
+not met.
+
+DISCLAIMER
+THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
+EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF
+MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT
+OF COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE
+COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY,
+INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
+DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING
+FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM
+OTHER DEALINGS IN THE FONT SOFTWARE.
