fat: fix oops on corrupted vfat fs

2014-12-03T17:36:03Z

a) don't bother with ->d_time for positives - we only check it for negatives anyway. b) make sure to set it at unlink and rmdir time - at *that* point soon-to-be negative dentry matches then-current directory contents c) don't go into renaming of old alias in vfat_lookup() unless it has the same parent (which it will, unless we are seeing corrupted image) [hirofumi@mail.parknet.co.jp: make change minimum, don't call d_move() for dir] Signed-off-by: Al Viro Signed-off-by: OGAWA Hirofumi Cc: [3.17.x] Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

jbd2: fix regression where we fail to initialize checksum seed when loading

2014-12-02T02:57:06Z

When we're enabling journal features, we cannot use the predicate jbd2_journal_has_csum_v2or3() because we haven't yet set the sb feature flag fields! Moreover, we just finished loading the shash driver, so the test is unnecessary; calculate the seed always. Without this patch, we fail to initialize the checksum seed the first time we turn on journal_checksum, which means that all journal blocks written during that first mount are corrupt. Transactions written after the second mount will be fine, since the feature flag will be set in the journal superblock. xfstests generic/{034,321,322} are the regression tests. (This is important for 3.18.) Signed-off-by: Darrick J. Wong Reported-by: Eric Whitney Signed-off-by: Theodore Ts'o

btrfs: zero out left over bytes after processing compression streams

2014-11-30T17:33:51Z

Don Bailey noticed that our page zeroing for compression at end-io time isn't complete. This reworks a patch from Linus to push the zeroing into the zlib and lzo specific functions instead of trying to handle the corners inside btrfs_decompress_buf2page Signed-off-by: Chris Mason Reviewed-by: Josef Bacik Reported-by: Don A.

Merge branch 'overlayfs-current' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs into for-linus

2014-11-21T16:51:08Z

"The biggest change is to rename the filesystem from "overlayfs" to "overlay". This will allow legacy overlayfs to be easily carried by distros alongside the new mainline one. Also fix a couple of copy-up races and allow escaping comma character in filenames." The last bit is about commas in pathname mount options...

ovl: ovl_dir_fsync() cleanup

2014-11-20T15:40:02Z

Check against !OVL_PATH_LOWER instead of OVL_PATH_MERGE. For a copied up directory the two are currently equivalent. Signed-off-by: Miklos Szeredi

ovl: pass dentry into ovl_dir_read_merged()

2014-11-20T15:40:01Z

Pass dentry into ovl_dir_read_merged() insted of upperpath and lowerpath. This cleans up callers and paves the way for multi-layer directory reads. Signed-off-by: Miklos Szeredi
