      "message": "ext34: ensure do_split leaves enough free space in both blocks\n\nThe do_split() function for htree dir blocks is intended to split a leaf\nblock to make room for a new entry.  It sorts the entries in the original\nblock by hash value, then moves the last half of the entries to the new\nblock - without accounting for how much space this actually moves.  (IOW,\nit moves half of the entry *count* not half of the entry *space*).  If by\nchance we have both large \u0026 small entries, and we move only the smallest\nentries, and we have a large new entry to insert, we may not have created\nenough space for it.\n\nThe patch below stores each record size when calculating the dx_map, and\nthen walks the hash-sorted dx_map, calculating how many entries must be\nmoved to more evenly split the existing entries between the old block and\nthe new block, guaranteeing enough space for the new entry.\n\nThe dx_map \"offs\" member is reduced to u16 so that the overall map size\ndoes not change - it is temporarily stored at the end of the new block, and\nif it grows too large it may be overwritten.  By making offs and size both\nu16, we won\u0027t grow the map size.\n\nAlso add a few comments to the functions involved.\n\nThis fixes the testcase reported by hooanon05@yahoo.co.jp on the\nlinux-ext4 list, \"ext3 dir_index causes an error\"\n\nThanks to Andreas Dilger for discussing the problem \u0026 solution with me.\n\nSigned-off-by: Eric Sandeen \u003csandeen@redhat.com\u003e\nSigned-off-by: Andreas Dilger \u003cadilger@clusterfs.com\u003e\nTested-by: Junjiro Okajima \u003chooanon05@yahoo.co.jp\u003e\nCc: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Then I\u0027ve found that ext3_read_inode() can call\nmake_bad_inode() without any error/warning messages, for example in the\nfollowing case:\n\n...\n        if (inode-\u003ei_nlink \u003d\u003d 0) {\n                if (inode-\u003ei_mode \u003d\u003d 0 ||\n                    !(EXT3_SB(inode-\u003ei_sb)-\u003es_mount_state \u0026 EXT3_ORPHAN_FS)) {\n                        /* this inode is deleted */\n                        brelse (bh);\n                        goto bad_inode;\n...\n\nBad inode can live some time, ext3_unlink can add it to orphan list, but\next3_delete_inode() do not deleted this inode from orphan list.  As result\nwe can have orphan list corruption detected in ext3_destroy_inode().\n\nHowever it is not clear for me how to fix this issue correctly.\n\nAs far as i see is_bad_inode() is called after iget() in all places\nexcluding ext3_lookup() and ext3_get_parent().  I believe it makes sense to\nadd bad inode check to these functions too and call iput if bad inode\ndetected.\n\nSigned-off-by:\tVasily Averin \u003cvvs@sw.ru\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

It is only supported by\nSLAB.\n\nI think its purpose was to have a callback after an object has been freed\nto verify that the state is the constructor state again?  The callback is\nperformed before each freeing of an object.\n\nI would think that it is much easier to check the object state manually\nbefore the free.  That also places the check near the code object\nmanipulation of the object.\n\nAlso the SLAB_DEBUG_INITIAL callback is only performed if the kernel was\ncompiled with SLAB debugging on.  If there would be code in a constructor\nhandling SLAB_DEBUG_INITIAL then it would have to be conditional on\nSLAB_DEBUG otherwise it would just be dead code.  But there is no such code\nin the kernel.  I think SLUB_DEBUG_INITIAL is too problematic to make real\nuse of, difficult to understand and there are easier ways to accomplish the\nsame effect (i.e.  add debug code before kfree).\n\nThere is a related flag SLAB_CTOR_VERIFY that is frequently checked to be\nclear in fs inode caches.  Remove the pointless checks (they would even be\npointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors.\n\nThis is the last slab flag that SLUB did not support.

      "message": "[PATCH] ext[34]: EA block reference count racing fix\n\nThere are race issues around ext[34] xattr block release code.\n\next[34]_xattr_release_block() checks the reference count of xattr block\n(h_refcount) and frees that xattr block if it is the last one reference it.\n Unlike ext2, the check of this counter is unprotected by any lock.\next[34]_xattr_release_block() will free the mb_cache entry before freeing\nthat xattr block.  There is a small window between the check for the re\nh_refcount \u003d\u003d1 and the call to mb_cache_entry_free().  During this small\nwindow another inode might find this xattr block from the mbcache and reuse\nit, racing a refcount updates.  The xattr block will later be freed by the\nfirst inode without notice other inode is still use it.  Later if that\nblock is reallocated as a datablock for other file, then more serious\nproblem might happen.\n\nWe need put a lock around places checking the refount as well to avoid\nracing issue.  Another place need this kind of protection is in\next3_xattr_block_set(), where it will modify the xattr block content in-\nthe-fly if the refcount is 1 (means it\u0027s the only inode reference it).\n\nThis will also fix another issue: the xattr block may not get freed at all\nif no lock is to protect the refcount check at the release time.  It is\npossible that the last two inodes could release the shared xattr block at\nthe same time.  But both of them think they are not the last one so only\ndecreased the h_refcount without freeing xattr block at all.\n\nWe need to call lock_buffer() after ext3_journal_get_write_access() to\navoid deadlock (because the later will call lock_buffer()/unlock_buffer\n() as well).\n\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nCc: Andreas Gruenbacher \u003cagruen@suse.de\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

We\ncould fix this at another level; but it seems most robust to avoid setting\nthe s_mount_opt flag in the first place (at the expense of more ifdefs).\n\nLikewise don\u0027t set the XATTR_USER flag when built without XATTR support.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Tigran Aivazian \u003ctigran@aivazian.fsnet.co.uk\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nCc: Andreas Gruenbacher \u003cagruen@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

At worst,\nthings spin out of control.\n\nAs you might guess, we found a couple places in ext3 where things spin out\nof control :)\n\nFirst, we had a corrupted directory that was never checked for\nconsistency...  it was corrupt, and pointed to another bad \"entry\" of\nlength 0.  The for() loop looped forever, since the length of\next3_next_entry(de) was 0, and we kept looking at the same pointer over and\nover and over and over...  I modeled this check and subsequent action on\nwhat is done for other directory types in ext3_readdir...\n\n(adding this check adds some computational expense; I am testing a followup\npatch to reduce the number of times we check and re-check these directory\nentries, in all cases.  Thanks for the idea, Andreas).\n\nNext we had a root directory inode which had a corrupted size, claimed to\nbe \u003e 200M on a 4M filesystem.  There was only really 1 block in the\ndirectory, but because the size was so large, readdir kept coming back for\nmore, spewing thousands of printk\u0027s along the way.\n\nPer Andreas\u0027 suggestion, if we\u0027re in this read error condition and we\u0027re\ntrying to read an offset which is greater than i_blocks worth of bytes,\nstop trying, and break out of the loop.\n\nWith these two changes fsfuzz test survives quite well on ext3.\n\nSigned-off-by: Eric Sandeen \u003csandeen@redhat.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] ext3: errors behaviour fix\n\nCurrent error behaviour for ext2 and ext3 filesystems does not fully\ncorrespond to the documentation and should be fixed.\n\nAccording to man 8 mount, ext2 and ext3 file systems allow to set one of 3\ndifferent on-errors behaviours:\n\n  ---- start of quote man 8 mount ----\n\n  errors\u003dcontinue / errors\u003dremount-ro / errors\u003dpanic\n\n    Define the behaviour when an error is encountered.  (Either ignore\n    errors and just mark the file system erroneous and continue, or remount\n    the file system read-only, or panic and halt the system.) The default is\n    set in the filesystem superblock, and can be changed using tune2fs(8).\n\n  ---- end of quote ----\n\nHowever EXT3_ERRORS_CONTINUE is not read from the superblock, and thus\nERRORS_CONT is not saved on the sbi-\u003es_mount_opt.  It leads to the incorrect\nhandle of errors on ext3.\n\nThen we\u0027ve checked corresponding code in ext2 and discovered that it is buggy\nas well:\n\n- EXT2_ERRORS_CONTINUE is not read from the superblock (the same);\n\n- parse_option() does not clean the alternative values and thus something\n  like (ERRORS_CONT|ERRORS_RO) can be set;\n\n- if options are omitted, parse_option() does not set any of these options.\n\nTherefore it is possible to set any combination of these options on the ext2:\n\n- none of them may be set: EXT2_ERRORS_CONTINUE on superblock / empty mount\n  options;\n\n- any of them may be set using mount options;\n\n- 2 any options may be set: by using EXT2_ERRORS_RO/EXT2_ERRORS_PANIC on the\n  superblock and other value in mount options;\n\n- and finally all three options may be set by adding third option in remount.\n\nCurrently ext2 uses these values only in ext2_error() and it is not leading to\nany noticeable troubles.  However somebody may be discouraged when he will try\nto workaround EXT2_ERRORS_PANIC on the superblock by using errors\u003dcontinue in\nmount options.\n\nThis patch:\n\nEXT3_ERRORS_CONTINUE should be taken from the superblock as default value for\nerror behaviour.\n\nSigned-off-by:\tDmitry Mishin \u003cdim@openvz.org\u003e\nAcked-by:\tVasily Averin \u003cvvs@sw.ru\u003e\nAcked-by: \tKirill Korotaev \u003cdev@openvz.org\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

Such behavior was hit number of times and noted to differ\nfrom that of 2.4.x kernels.\n\nThis patch fixes this:\n- do nothing in case of EXT3_ERRORS_CONTINUE,\n- set EXT3_MOUNT_ABORT and call journal_abort() in all other cases\n- panic() should be called after ext3_commit_super() to save\n sb marked as EXT3_ERROR_FS\n\nSigned-off-by: Vasily Averin \u003cvvs@sw.ru\u003e\nAcked-by: Kirill Korotaev \u003cdev@sw.ru\u003e\nCc: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\nCc: \"Stephen C.

Quota code makes sure (by resetting inode operations and\n| setting special flag on inode) that noone tries to enter quota code\n| while holding i_mutex on a quota file...\n\nThe good news is that all of this special case i_mutex grabbing happens in the\n(per filesystem) low level quota write function.

While\ntrying to fix them, it seems quite confusing in the ext3 code where some\nblocks are filesystem-wide blocks, some are group relative offsets that need\nto be signed value (as -1 has special meaning).  So it seem saner to define\ntwo types of physical blocks: one is filesystem wide blocks, another is\ngroup-relative blocks.  The following patches clarify these two types of\nblocks in the ext3 code, and fix the type bugs which limit current 32 bit ext3\nfilesystem limit to 8TB.\n\nWith this series of patches and the percpu counter data type changes in the mm\ntree, we are able to extend exts filesystem limit to 16TB.\n\nThis work is also a pre-request for the recent \u003e32 bit ext3 work, and makes\nthe kernel to able to address 48 bit ext3 block a lot easier: Simply redefine\next3_fsblk_t from unsigned long to sector_t and redefine the format string for\next3 filesystem block corresponding.\n\nTwo RFC with a series patches have been posted to ext2-devel list and have\nbeen reviewed and discussed:\nhttp://marc.theaimsgroup.com/?l\u003dext2-devel\u0026m\u003d114722190816690\u0026w\u003d2\n\nhttp://marc.theaimsgroup.com/?l\u003dext2-devel\u0026m\u003d114784919525942\u0026w\u003d2\n\nPatches are tested on both 32 bit machine and 64 bit machine, \u003c8TB ext3 and\n\u003e8TB ext3 filesystem(with the latest to be released e2fsprogs-1.39).

      "message": "[PATCH] VFS: Permit filesystem to perform statfs with a known root dentry\n\nGive the statfs superblock operation a dentry pointer rather than a superblock\npointer.\n\nThis complements the get_sb() patch.  That reduced the significance of\nsb-\u003es_root, allowing NFS to place a fake root there.  However, NFS does\nrequire a dentry to use as a target for the statfs operation.  This permits\nthe root in the vfsmount to be used instead.\n\nlinux/mount.h has been added where necessary to make allyesconfig build\nsuccessfully.\n\nInterest has also been expressed for use with the FUSE and XFS filesystems.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] VFS: Permit filesystem to override root dentry on mount\n\nExtend the get_sb() filesystem operation to take an extra argument that\npermits the VFS to pass in the target vfsmount that defines the mountpoint.\n\nThe filesystem is then required to manually set the superblock and root dentry\npointers.  For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing.  In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n     pointer argument and return an integer, so most filesystems have to change\n     very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n     normally call simple_set_mnt() to instantiate the vfsmount. This will\n     always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n     dcache upon superblock destruction rather than shrink_dcache_anon().\n\n     This is required because the superblock may now have multiple trees that\n     aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n     currently called functions assume that the whole tree is rooted at s_root,\n     and that anonymous dentries are not the roots of trees which results in\n     dentries being left unculled.\n\n     However, with the way NFS superblock sharing are currently set to be\n     implemented, these assumptions are violated: the root of the filesystem is\n     simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n     inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n     with child trees.\n\n     [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n     changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
