2009-07-23ocfs2: Fix initialization of blockcheck statsJan Kara

2009-07-23ocfs2: Initialize blocks allocated to local quota fileJan Kara

2009-07-23ocfs2: Make global quota files blocksize alignedJan Kara
Change i_size of global quota files so that it always remains aligned to block size. This is mainly because the end of quota block may contain checksum (if checksumming is enabled) and it's a bit awkward for it to be "outside" of quota file (and it makes life harder for ocfs2-tools).

2009-07-23ocfs2: Use ocfs2_rec_clusters in ocfs2_adjust_adjacent_records.Tao Ma
In ocfs2_adjust_adjacent_records, we will adjust adjacent records according to the extent_list in the lower level. But actually the lower level tree will either be a leaf or a branch. If we only use ocfs2_is_empty_extent we will meet with some problem if the lower tree is a branch (tree_depth > 1). So use !ocfs2_rec_clusters instead. And actually only the leaf record can have holes. So add a BUG_ON for non-leaf branch. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
2009-07-23jfs: Fix early release of acl in jfs_get_aclStefan Bader
BugLink: http://bugs.launchpad.net/ubuntu/+bug/396780 Commit 073aaa1b142461d91f83da66db1184d7c1b1edea "helpers for acl caching + switch to those" introduced new helper functions for acl handling but seems to have introduced a regression for jfs as the acl is released before returning it to the caller, instead of leaving this for the caller to do. This causes the acl object to be used after freeing it, leading to kernel panics in completely different places. Thanks to Christophe Dumez for reporting and bisecting into this.

2009-07-22cifs: fix sb->s_maxbytes so that it casts properly to a signed valueJeff Layton
This off-by-one bug causes sendfile() to not work properly. When a task calls sendfile() on a file on a CIFS filesystem, the syscall returns -1 and sets errno to EOVERFLOW. do_sendfile uses s_maxbytes to verify the returned offset of the file. The problem there is that this value is cast to a signed value (loff_t). When this is done on the s_maxbytes value that cifs uses, it becomes negative and the comparisons against it fail. Even though s_maxbytes is an unsigned value, it seems that it's not OK to set it in such a way that it'll end up negative when it's cast to a signed value. These casts happen in other codepaths besides sendfile too, but the VFS is a little hard to follow in this area and I can't be sure if there are other bugs that this will fix. It's not clear to me why s_maxbytes isn't just declared as loff_t in the first place, but either way we still need to fix these values to make sendfile work properly. This is also an opportunity to replace the magic bit-shift values here with the standard #defines for this. This fixes the reproducer program I have that does a sendfile and will probably also fix the situation where apache is serving from a CIFS share.

2009-07-22Btrfs: Remove broken sanity check from btrfs_rmap_block()David Woodhouse
It was never actually doing anything anyway (see the loop condition), and it would be difficult to make it work for RAID[56]. Even if it was actually working, it's checking for the wrong thing anyway. Instead of checking whether we list a block which _doesn't_ land at the relevant physical location, it should be checking that we _have_ listed all the logical blocks which refer to the required physical location on all devices. This function is only called from remove_sb_from_cache() to ensure that we reserve the logical blocks which would reside at the same physical location as the superblock copies. So listing more blocks than we need is actually OK. With RAID[56] we're going to throw away an entire stripe for each block we have to ignore, so we _are_ going to list blocks other than the ones which actually contain the superblock.

2009-07-22Btrfs: fix locking issue in btrfs_find_next_keyYan Zheng
When walking up the tree, btrfs_find_next_key assumes the upper level tree block is properly locked. This isn't always true even path->keep_locks is 1. This is because btrfs_find_next_key may advance path->slots[] several times instead of only once. When 'path->slots[level] >= btrfs_header_nritems(path->nodes[level])' is found, we can't guarantee the original value of 'path->slots[level]' is 'btrfs_header_nritems(path->nodes[level]) - 1'. If it's not, the tree block at 'level + 1' isn't locked. This patch fixes the issue by explicitly checking the locking state, re-searching the tree if it's not locked.

2009-07-21NFSv4: Fix a problem whereby a buggy server can oops the kernelTrond Myklebust
We just had a case in which a buggy server occasionally returns the wrong attributes during an OPEN call. While the client does catch this sort of condition in nfs4_open_done(), and causes the nfs4_atomic_open() to return -EISDIR, the logic in nfs_atomic_lookup() is broken, since it causes a fallback to an ordinary lookup instead of just returning the error. When the buggy server then returns a regular file for the fallback lookup, the VFS allows the open, and bad things start to happen, since the open file doesn't have any associated NFSv4 state. The fix is firstly to return the EISDIR/ENOTDIR errors immediately, and secondly to ensure that we are always careful when dereferencing the nfs_open_context state pointer.

2009-07-21ocfs2: Fix deadlock on umountJan Kara
In commit ea455f8ab68338ba69f5d3362b342c115bea8e13, we moved the dentry lock put process into ocfs2_wq. This causes problems during umount because ocfs2_wq can drop references to inodes while they are being invalidated by invalidate_inodes() causing all sorts of nasty things (invalidate_inodes() ending in an infinite loop, "Busy inodes after umount" messages etc.). We fix the problem by stopping ocfs2_wq from doing any further releasing of inode references on the superblock being unmounted, wait until it finishes the current round of releasing and finally cleaning up all the references in dentry_lock_list from ocfs2_put_super().

2009-07-21fsnotify: fix inotify tail drop check with path entriesEric Paris
fsnotify drops new events when they are the same as the tail event on the queue to be sent to userspace. The problem is that if the event comes with a path we forget to break out of the switch statement and fall into the code path which matches on events that do not have any type of file backed information (things like IN_UNMOUNT and IN_Q_OVERFLOW). The problem is that this code thinks all such events should be dropped. Fix is to add a break. Signed-off-by: Eric Paris <eparis@redhat.com>
2009-07-21inotify: check filename before dropping repeat eventsEric Paris
inotify drops events if the last event on the queue is the same as the current event. But it does 2 things wrong. First it is comparing old->inode with new->inode. But after an event if put on the queue the ->inode is no longer allowed to be used. It's possible between the last event and this new event the inode could be reused and we would falsely match the inode's memory address between two differing events. The second problem is that when a file is removed fsnotify is passed the negative dentry for the removed object rather than the postive dentry from immediately before the removal. This mean the (broken) inotify tail drop code was matching the NULL ->inode of differing events. The fix is to check the file name which is stored with events when doing the tail drop instead of wrongly checking the address of the stored ->inode.

2009-07-21inotify: fix error paths in inotify_update_watchEric Paris
inotify_update_watch could leave things in a horrid state on a number of error paths. We could try to remove idr entries that didn't exist, we could send an IN_IGNORED to userspace for watches that don't exist, and a bit of other stupidity. Clean these up by doing the idr addition before we put the mark on the inode since we can clean that up on error and getting off the inode's mark list is hard.

2009-07-21inotify: do not leak inode marks in inotify_add_watchEric Paris
inotify_add_watch had a couple of problems. The biggest being that if inotify_add_watch was called on the same inode twice (to update or change the event mask) a refence was taken on the original inode mark by fsnotify_find_mark_entry but was not being dropped at the end of the inotify_add_watch call. Thus if inotify_rm_watch was called although the mark was removed from the inode, the refcnt wouldn't hit zero and we would leak memory.

2009-07-21inotify: drop user watch count when a watch is removedEric Paris

Get rid of extenddisksize parameter of ext3_get_blocks_handle(). This seems to be a relict from some old days and setting disksize in this function does not make much sence. Currently it was set only by ext3_getblk(). Since the parameter has some effect only if create == 1, it is easy to check that the three callers which end up calling ext3_getblk() with create == 1 (ext3_append, ext3_quota_write, ext3_mkdir) do the right thing and set disksize themselves.

2009-07-15jbd: Fix a race between checkpointing code and journal_get_write_access()Jan Kara
The following race can happen: CPU1 CPU2 checkpointing code checks the buffer, adds it to an array for writeback do_get_write_access() ... lock_buffer() unlock_buffer() flush_batch() submits the buffer for IO __jbd_journal_file_buffer() So a buffer under writeout is returned from do_get_write_access(). Since the filesystem code relies on the fact that journaled buffers cannot be written out, it does not take the buffer lock and so it can modify buffer while it is under writeout. That can lead to a filesystem corruption if we crash at the right moment. The similar problem can happen with the journal_get_create_access() path. We fix the problem by clearing the buffer dirty bit under buffer_lock even if the buffer is on BJ_None list. Actually, we clear the dirty bit regardless the list the buffer is in and warn about the fact if the buffer is already journalled.

2009-07-15ext3: Fix truncation of symlinks after failed writeJan Kara
Contents of long symlinks is written via standard write methods. So when the write fails, we add inode to orphan list. But symlinks don't have .truncate method defined so nobody properly removes them from the orphan list (both on disk and in memory). Fix this by calling ext3_truncate() directly instead of calling vmtruncate() (which is saner anyway since we don't need anything vmtruncate() does except from calling .truncate in these paths). We also add inode to orphan list only if ext3_can_truncate() is true (currently, it can be false for symlinks when there are no blocks allocated) - otherwise orphan list processing will complain and ext3_truncate() will not remove inode from on-disk orphan list.
