2010-06-11Btrfs: The file argument for fsync() is never nullDan Carpenter1-1/+1
The "file" argument for fsync is never null so we can remove this check. What drew my attention here is that 7ea8085910e: "drop unused dentry argument to ->fsync" introduced an unconditional dereference at the start of the function and that generated a smatch warning.

2010-06-11Btrfs: avoid BUG when dropping root and reference in same transactionSage Weil1-3/+0
If btrfs_ioctl_snap_destroy() deletes a snapshot but finishes with end_transaction(), the cleaner kthread may come in and drop the root in the same transaction. If that's the case, the root's refs still == 1 in the tree when btrfs_del_root() deletes the item, because commit_fs_roots() hasn't updated it yet (that happens during the commit). This wasn't a problem before only because btrfs_ioctl_snap_destroy() would commit the transaction before dropping the dentry reference, so the dead root wouldn't get queued up until after the fs root item was updated in the btree. Since it is not an error to drop the root reference and the root in the same transaction, just drop the BUG_ON() in btrfs_del_root().

2010-06-11Btrfs: prohibit a operation of changing acl's mask when noacl mount option usedShi Weihua1-0/+3
when used Posix File System Test Suite(pjd-fstest) to test btrfs, some cases about setfacl failed when noacl mount option used. I simplified used commands in pjd-fstest, and the following steps can reproduce it. ------------------------ # cd btrfs-part/ # mkdir aaa # setfacl -m m::rw aaa <- successed, but not expected by pjd-fstest. ------------------------ I checked ext3, a warning message occured, like as: setfacl: aaa/: Operation not supported Certainly, it's expected by pjd-fstest. So, i compared acl.c of btrfs and ext3. Based on that, a patch created. Fortunately, it works. Signed-off-by: Shi Weihua <shiwh@cn.fujitsu.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
2010-06-11Btrfs: should add a permission check for setfaclShi Weihua1-0/+3
On btrfs, do the following ------------------ # su user1 # cd btrfs-part/ # touch aaa # getfacl aaa # file: aaa # owner: user1 # group: user1 user::rw- group::rw- other::r-- # su user2 # cd btrfs-part/ # setfacl -m u::rwx aaa # getfacl aaa # file: aaa # owner: user1 # group: user1 user::rwx <- successed to setfacl group::rw- other::r-- ------------------ but we should prohibit it that user2 changing user1's acl. In fact, on ext3 and other fs, a message occurs: setfacl: aaa: Operation not permitted This patch fixed it.

2010-06-10ceph: try to send partial cap release on cap message on missing inodeSage Weil3-5/+9
If we have enough memory to allocate a new cap release message, do so, so that we can send a partial release message immediately.

2010-06-04fix truncate inode time modification breakageNick Piggin1-1/+1
mtime and ctime should be changed only if the file size has actually changed. Patches changing ext2 and tmpfs from vmtruncate to new truncate sequence has caused regressions where they always update timestamps. There is some strange cases in POSIX where truncate(2) must not update times unless the size has acutally changed, see 6e656be89. This area is all still rather buggy in different ways in a lot of filesystems and needs a cleanup and audit (ideally the vfs will provide a simple attribute or call to direct all filesystems exactly which attributes to change). But coming up with the best solution will take a while and is not appropriate for rc anyway. So fix recent regression for now.
