However, when tiled -+ * it does it a little differently, since one walks addresses not just in the -+ * X direction but also Y. So, along with alternating channels when bit -+ * 6 of the address flips, it also alternates when other bits flip -- Bits 9 -+ * (every 512 bytes, an X tile scanline) and 10 (every two X tile scanlines) -+ * are common to both the 915 and 965-class hardware. -+ * -+ * The CPU also sometimes XORs in higher bits as well, to improve -+ * bandwidth doing strided access like we do so frequently in graphics.

No two branches can have the same priority. -+ -+ -+Branch Mode: -+============ -+ -+Each branch is assigned a mode - read-write or read-only. This allows -+directories on media mounted read-write to be used in a read-only manner. -+ -+ -+Whiteouts: -+========== -+ -+A whiteout removes a file name from the namespace. Whiteouts are needed when -+one attempts to remove a file on a read-only branch. -+ -+Suppose we have a two-branch union, where branch 0 is read-write and branch -+1 is read-only. And a file 'foo' on branch 1: -+ -+./b0/ -+./b1/ -+./b1/foo -+ -+The unified view would simply be: -+ -+./union/ -+./union/foo -+ -+Since 'foo' is stored on a read-only branch, it cannot be removed. A -+whiteout is used to remove the name 'foo' from the unified namespace. Again, -+since branch 1 is read-only, the whiteout cannot be created there. So, we -+try on a higher priority (lower numerically) branch and create the whiteout -+there. -+ -+./b0/ -+./b0/.wh.foo -+./b1/ -+./b1/foo -+ -+Later, when Unionfs traverses branches (due to lookup or readdir), it -+eliminate 'foo' from the namespace (as well as the whiteout itself.) -+ -+ -+Opaque Directories: -+=================== -+ -+Assume we have a unionfs mount comprising of two branches. Branch 0 is -+empty; branch 1 has the directory /a and file /a/f. Let's say we mount a -+union of branch 0 as read-write and branch 1 as read-only. Now, let's say -+we try to perform the following operation in the union: -+ -+ rm -fr a -+ -+Because branch 1 is not writable, we cannot physically remove the file /a/f -+or the directory /a. So instead, we will create a whiteout in branch 0 -+named /.wh.a, masking out the name "a" from branch 1. Next, let's say we -+try to create a directory named "a" as follows: -+ -+ mkdir a -+ -+Because we have a whiteout for "a" already, Unionfs behaves as if "a" -+doesn't exist, and thus will delete the whiteout and replace it with an -+actual directory named "a". -+ -+The problem now is that if you try to "ls" in the union, Unionfs will -+perform is normal directory name unification, for *all* directories named -+"a" in all branches. This will cause the file /a/f from branch 1 to -+re-appear in the union's namespace, which violates Unix semantics. -+ -+To avoid this problem, we have a different form of whiteouts for -+directories, called "opaque directories" (same as BSD Union Mount does). -+Whenever we replace a whiteout with a directory, that directory is marked as -+opaque. In Unionfs 2.x, it means that we create a file named -+/a/.wh.__dir_opaque in branch 0, after having created directory /a there. -+When unionfs notices that a directory is opaque, it stops all namespace -+operations (including merging readdir contents) at that opaque directory. -+This prevents re-exposing names from masked out directories. -+ -+ -+Duplicate Elimination: -+====================== -+ -+It is possible for files on different branches to have the same name. -+Unionfs then has to select which instance of the file to show to the user. -+Given the fact that each branch has a priority associated with it, the -+simplest solution is to take the instance from the highest priority -+(numerically lowest value) and "hide" the others. -+ -+ -+Unlinking: -+========= -+ -+Unlink operation on non-directory instances is optimized to remove the -+maximum possible objects in case multiple underlying branches have the same -+file name. The unlink operation will first try to delete file instances -+from highest priority branch and then move further to delete from remaining -+branches in order of their decreasing priority. Consider a case (F..D..F), -+where F is a file and D is a directory of the same name; here, some -+intermediate branch could have an empty directory instance with the same -+name, so this operation also tries to delete this directory instance and -+proceed further to delete from next possible lower priority branch. The -+unionfs unlink operation will smoothly delete the files with same name from -+all possible underlying branches. In case if some error occurs, it creates -+whiteout in highest priority branch that will hide file instance in rest of -+the branches. An error could occur either if an unlink operations in any of -+the underlying branch failed or if a branch has no write permission. -+ -+This unlinking policy is known as "delete all" and it has the benefit of -+overall reducing the number of inodes used by duplicate files, and further -+reducing the total number of inodes consumed by whiteouts. The cost is of -+extra processing, but testing shows this extra processing is well worth the -+savings. -+ -+ -+Copyup: -+======= -+ -+When a change is made to the contents of a file's data or meta-data, they -+have to be stored somewhere. The best way is to create a copy of the -+original file on a branch that is writable, and then redirect the write -+though to this copy. The copy must be made on a higher priority branch so -+that lookup and readdir return this newer "version" of the file rather than -+the original (see duplicate elimination). -+ -+An entire unionfs mount can be read-only or read-write. If it's read-only, -+then none of the branches will be written to, even if some of the branches -+are physically writeable. If the unionfs mount is read-write, then the -+leftmost (highest priority) branch must be writeable (for copyup to take -+place); the remaining branches can be any mix of read-write and read-only. -+ -+In a writeable mount, unionfs will create new files/dir in the leftmost -+branch. If one tries to modify a file in a read-only branch/media, unionfs -+will copyup the file to the leftmost branch and modify it there. If you try -+to modify a file from a writeable branch which is not the leftmost branch, -+then unionfs will modify it in that branch; this is useful if you, say, -+unify differnet packages (e.g., apache, sendmail, ftpd, etc.) and you want -+changes to specific package files to remain logically in the directory where -+they came from. -+ -+Cache Coherency: -+================ -+ -+Unionfs users often want to be able to modify files and directories directly -+on the lower branches, and have those changes be visible at the Unionfs -+level. This means that data (e.g., pages) and meta-data (dentries, inodes, -+open files, etc.) have to be synchronized between the upper and lower -+layers. In other words, the newest changes from a layer below have to be -+propagated to the Unionfs layer above. If the two layers are not in sync, a -+cache incoherency ensues, which could lead to application failures and even -+oopses. The Linux kernel, however, has a rather limited set of mechanisms -+to ensure this inter-layer cache coherency---so Unionfs has to do most of -+the hard work on its own. -+ -+Maintaining Invariants: -+ -+The way Unionfs ensures cache coherency is as follows. At each entry point -+to a Unionfs file system method, we call a utility function to validate the -+primary objects of this method. Generally, we call unionfs_file_revalidate -+on open files, and __unionfs_d_revalidate_chain on dentries (which also -+validates inodes). These utility functions check to see whether the upper -+Unionfs object is in sync with any of the lower objects that it represents. -+The checks we perform include whether the Unionfs superblock has a newer -+generation number, or if any of the lower objects mtime's or ctime's are -+newer. (Note: generation numbers change when branch-management commands are -+issued, so in a way, maintaining cache coherency is also very important for -+branch-management.) If indeed we determine that any Unionfs object is no -+longer in sync with its lower counterparts, then we rebuild that object -+similarly to how we do so for branch-management. -+ -+While rebuilding Unionfs's objects, we also purge any page mappings and -+truncate inode pages (see fs/unionfs/dentry.c:purge_inode_data). This is to -+ensure that Unionfs will re-get the newer data from the lower branches. We -+perform this purging only if the Unionfs operation in question is a reading -+operation; if Unionfs is performing a data writing operation (e.g., ->write, -+->commit_write, etc.) then we do NOT flush the lower mappings/pages: this is -+because (1) a self-deadlock could occur and (2) the upper Unionfs pages are -+considered more authoritative anyway, as they are newer and will overwrite -+any lower pages. -+ -+Unionfs maintains the following important invariant regarding mtime's, -+ctime's, and atime's: the upper inode object's times are the max() of all of -+the lower ones. For non-directory objects, there's only one object below, -+so the mapping is simple; for directory objects, there could me multiple -+lower objects and we have to sync up with the newest one of all the lower -+ones. This invariant is important to maintain, especially for directories -+(besides, we need this to be POSIX compliant). A union could comprise -+multiple writable branches, each of which could change. If we don't reflect -+the newest possible mtime/ctime, some applications could fail. For example, -+NFSv2/v3 exports check for newer directory mtimes on the server to determine -+if the client-side attribute cache should be purged. -+ -+To maintain these important invariants, of course, Unionfs carefully -+synchronizes upper and lower times in various places. For example, if we -+copy-up a file to a top-level branch, the parent directory where the file -+was copied up to will now have a new mtime: so after a successful copy-up, -+we sync up with the new top-level branch's parent directory mtime. -+ -+Implementation: -+ -+This cache-coherency implementation is efficient because it defers any -+synchronizing between the upper and lower layers until absolutely needed. -+Consider the example a common situation where users perform a lot of lower -+changes, such as untarring a whole package. While these take place, -+typically the user doesn't access the files via Unionfs; only after the -+lower changes are done, does the user try to access the lower files. With -+our cache-coherency implementation, the entirety of the changes to the lower -+branches will not result in a single CPU cycle spent at the Unionfs level -+until the user invokes a system call that goes through Unionfs. -+ -+We have considered two alternate cache-coherency designs. (1) Using the -+dentry/inode notify functionality to register interest in finding out about -+any lower changes. This is a somewhat limited and also a heavy-handed -+approach which could result in many notifications to the Unionfs layer upon -+each small change at the lower layer (imagine a file being modified multiple -+times in rapid succession). (2) Rewriting the VFS to support explicit -+callbacks from lower objects to upper objects. We began exploring such an -+implementation, but found it to be very complicated--it would have resulted -+in massive VFS/MM changes which are unlikely to be accepted by the LKML -+community. We therefore believe that our current cache-coherency design and -+implementation represent the best approach at this time. -+ -+Limitations: -+ -+Our implementation works in that as long as a user process will have caused -+Unionfs to be called, directly or indirectly, even to just do -+->d_revalidate; then we will have purged the current Unionfs data and the -+process will see the new data. For example, a process that continually -+re-reads the same file's data will see the NEW data as soon as the lower -+file had changed, upon the next read(2) syscall (even if the file is still -+open!) However, this doesn't work when the process re-reads the open file's -+data via mmap(2) (unless the user unmaps/closes the file and remaps/reopens -+it). Once we respond to ->readpage(s), then the kernel maps the page into -+the process's address space and there doesn't appear to be a way to force -+the kernel to invalidate those pages/mappings, and force the process to -+re-issue ->readpage. If there's a way to invalidate active mappings and -+force a ->readpage, let us know please (invalidate_inode_pages2 doesn't do -+the trick). -+ -+Our current Unionfs code has to perform many file-revalidation calls. It -+would be really nice if the VFS would export an optional file system hook -+->file_revalidate (similarly to dentry->d_revalidate) that will be called -+before each VFS op that has a "struct file" in it. -+ -+Certain file systems have micro-second granularity (or better) for inode -+times, and asynchronous actions could cause those times to change with some -+small delay. In such cases, Unionfs may see a changed inode time that only -+differs by a tiny fraction of a second: such a change may be a false -+positive indication that the lower object has changed, whereas if unionfs -+waits a little longer, that false indication will not be seen. (These false -+positives are harmless, because they would at most cause unionfs to -+re-validate an object that may need no revalidation, and print a debugging -+message that clutters the console/logs.) Therefore, to minimize the chances -+of these situations, we delay the detection of changed times by a small -+factor of a few seconds, called UNIONFS_MIN_CC_TIME (which defaults to 3 -+seconds, as does NFS). This means that we will detect the change, only a -+couple of seconds later, if indeed the time change persists in the lower -+file object. This delayed detection has an added performance benefit: we -+reduce the number of times that unionfs has to revalidate objects, in case -+there's a lot of concurrent activity on both the upper and lower objects, -+for the same file(s). Lastly, this delayed time attribute detection is -+similar to how NFS clients operate (e.g., acregmin). -+ -+Finally, there is no way currently in Linux to prevent lower directories -+from being moved around (i.e., topology changes); there's no way to prevent -+modifications to directory sub-trees of whole file systems which are mounted -+read-write. It is therefore possible for in-flight operations in unionfs to -+take place, while a lower directory is being moved around. Therefore, if -+you try to, say, create a new file in a directory through unionfs, while the -+directory is being moved around directly, then the new file may get created -+in the new location where that directory was moved to. This is a somewhat -+similar behaviour in NFS: an NFS client could be creating a new file while -+th NFS server is moving th directory around; the file will get successfully -+created in the new location. (The one exception in unionfs is that if the -+branch is marked read-only by unionfs, then a copyup will take place.) -+ -+For more information, see <http://unionfs.filesystems.org/>. -diff --git a/Documentation/filesystems/unionfs/issues.txt b/Documentation/filesystems/unionfs/issues.txt -new file mode 100644 -index 0000000..f4b7e7e ---- /dev/null -+++ b/Documentation/filesystems/unionfs/issues.txt -@@ -0,0 +1,28 @@ -+KNOWN Unionfs 2.x ISSUES: -+========================= -+ -+1.

See the Copyup section in -+concepts.txt, for a description of Unionfs's behavior when mixing read-only -+and read-write branches and mounts. -+ -+Syntax: -+ -+ dirs=/branch1[=ro|=rw]:/branch2[=ro|=rw]:...:/branchN[=ro|=rw] -+ -+Example: -+ -+ dirs=/writable_branch=rw:/read-only_branch=ro -+ -+ -+BRANCH MANAGEMENT -+================= -+ -+Once you mount your union for the first time, using the "dirs=" option, you -+can then change the union's overall mode or reconfigure the branches, using -+the remount option, as follows. -+ -+To downgrade a union from read-write to read-only: -+ -+# mount -t unionfs -o remount,ro none MOUNTPOINT -+ -+To upgrade a union from read-only to read-write: -+ -+# mount -t unionfs -o remount,rw none MOUNTPOINT -+ -+To delete a branch /foo, regardless where it is in the current union: -+ -+# mount -t unionfs -o remount,del=/foo none MOUNTPOINT -+ -+To insert (add) a branch /foo before /bar: -+ -+# mount -t unionfs -o remount,add=/bar:/foo none MOUNTPOINT -+ -+To insert (add) a branch /foo (with the "rw" mode flag) before /bar: -+ -+# mount -t unionfs -o remount,add=/bar:/foo=rw none MOUNTPOINT -+ -+To insert (add) a branch /foo (in "rw" mode) at the very beginning (i.e., a -+new highest-priority branch), you can use the above syntax, or use a short -+hand version as follows: -+ -+# mount -t unionfs -o remount,add=/foo none MOUNTPOINT -+ -+To append a branch to the very end (new lowest-priority branch): -+ -+# mount -t unionfs -o remount,add=:/foo none MOUNTPOINT -+ -+To append a branch to the very end (new lowest-priority branch), in -+read-only mode: -+ -+# mount -t unionfs -o remount,add=:/foo=ro none MOUNTPOINT -+ -+Finally, to change the mode of one existing branch, say /foo, from read-only -+to read-write, and change /bar from read-write to read-only: -+ -+# mount -t unionfs -o remount,mode=/foo=rw,mode=/bar=ro none MOUNTPOINT -+ -+Note: in Unionfs 2.x, you cannot set the leftmost branch to readonly because -+then Unionfs won't have any writable place for copyups to take place. -+Moreover, the VFS can get confused when it tries to modify something in a -+file system mounted read-write, but isn't permitted to write to it. -+Instead, you should set the whole union as readonly, as described above. -+If, however, you must set the leftmost branch as readonly, perhaps so you -+can get a snapshot of it at a point in time, then you should insert a new -+writable top-level branch, and mark the one you want as readonly. This can -+be accomplished as follows, assuming that /foo is your current leftmost -+branch: -+ -+# mount -t tmpfs -o size=NNN /new -+# mount -t unionfs -o remount,add=/new,mode=/foo=ro none MOUNTPOINT -+<do what you want safely in /foo> -+# mount -t unionfs -o remount,del=/new,mode=/foo=rw none MOUNTPOINT -+<check if there's anything in /new you want to preserve> -+# umount /new -+ -+CACHE CONSISTENCY -+================= -+ -+If you modify any file on any of the lower branches directly, while there is -+a Unionfs 2.x mounted above any of those branches, you should tell Unionfs -+to purge its caches and re-get the objects. To do that, you have to -+increment the generation number of the superblock using the following -+command: -+ -+# mount -t unionfs -o remount,incgen none MOUNTPOINT -+ -+Note that the older way of incrementing the generation number using an -+ioctl, is no longer supported in Unionfs 2.0 and newer. Ioctls in general -+are not encouraged. Plus, an ioctl is per-file concept, whereas the -+generation number is a per-file-system concept. Worse, such an ioctl -+requires an open file, which then has to be invalidated by the very nature -+of the generation number increase (read: the old generation increase ioctl -+was pretty racy). -+ -+ -+For more information, see <http://unionfs.filesystems.org/>. -diff --git a/MAINTAINERS b/MAINTAINERS -index deedc0d..c722f8e 100644 ---- a/MAINTAINERS -+++ b/MAINTAINERS -@@ -4173,6 +4173,14 @@ L: linux-kernel@vger.kernel.org - W: http://www.kernel.dk - S: Maintained - -+UNIONFS -+P: Erez Zadok -+M: ezk@cs.sunysb.edu -+L: unionfs@filesystems.org -+W: http://unionfs.filesystems.org -+T: git git.kernel.org/pub/scm/linux/kernel/git/ezk/unionfs.git -+S: Maintained -+ - USB ACM DRIVER - P: Oliver Neukum - M: oliver@neukum.name -diff --git a/fs/Kconfig b/fs/Kconfig -index d387358..31610a2 100644 ---- a/fs/Kconfig -+++ b/fs/Kconfig -@@ -981,6 +981,47 @@ config CONFIGFS_FS - - endmenu - -+menu "Layered filesystems" -+ -+config ECRYPT_FS -+ tristate "eCrypt filesystem layer support (EXPERIMENTAL)" -+ depends on EXPERIMENTAL && KEYS && CRYPTO && NET -+ help -+ Encrypted filesystem that operates on the VFS layer.

However, when tiled -+ * it does it a little differently, since one walks addresses not just in the -+ * X direction but also Y. So, along with alternating channels when bit -+ * 6 of the address flips, it also alternates when other bits flip -- Bits 9 -+ * (every 512 bytes, an X tile scanline) and 10 (every two X tile scanlines) -+ * are common to both the 915 and 965-class hardware. -+ * -+ * The CPU also sometimes XORs in higher bits as well, to improve -+ * bandwidth doing strided access like we do so frequently in graphics. This -+ * is called "Channel XOR Randomization" in the MCH documentation. The result -+ * is that the CPU is XORing in either bit 11 or bit 17 to bit 6 of its address -+ * decode. -+ * -+ * All of this bit 6 XORing has an effect on our memory management, -+ * as we need to make sure that the 3d driver can correctly address object -+ * contents. -+ * -+ * If we don't have interleaved memory, all tiling is safe and no swizzling is -+ * required. -+ * -+ * When bit 17 is XORed in, we simply refuse to tile at all. Bit -+ * 17 is not just a page offset, so as we page an objet out and back in, -+ * individual pages in it will have different bit 17 addresses, resulting in -+ * each 64 bytes being swapped with its neighbor! -+ * -+ * Otherwise, if interleaved, we have to tell the 3d driver what the address -+ * swizzling it needs to do is, since it's writing with the CPU to the pages -+ * (bit 6 and potentially bit 11 XORed in), and the GPU is reading from the -+ * pages (bit 6, 9, and 10 XORed in), resulting in a cumulative bit swizzling -+ * required by the CPU of XORing in bit 6, 9, 10, and potentially 11, in order -+ * to match what the GPU expects. -+ */ -+ -+/** -+ * Detects bit 6 swizzling of address lookup between IGD access and CPU -+ * access through main memory. -+ */ -+void -+i915_gem_detect_bit_6_swizzle(struct drm_device *dev) -+{ -+ drm_i915_private_t *dev_priv = dev->dev_private; -+ uint32_t swizzle_x = I915_BIT_6_SWIZZLE_UNKNOWN; -+ uint32_t swizzle_y = I915_BIT_6_SWIZZLE_UNKNOWN; -+ -+ if (!IS_I9XX(dev)) { -+ /* As far as we know, the 865 doesn't have these bit 6 -+ * swizzling issues. -+ */ -+ swizzle_x = I915_BIT_6_SWIZZLE_NONE; -+ swizzle_y = I915_BIT_6_SWIZZLE_NONE; -+ } else if (!IS_I965G(dev) || IS_I965GM(dev)) { -+ uint32_t dcc; -+ -+ /* On 915-945 and GM965, channel interleave by the CPU is -+ * determined by DCC.
