When attempting an initial mount, we should only attempt other authflavors if AUTH_UNIX receives a NFS4ERR_WRONGSEC error. This allows other errors to be passed back to userspace programs.

2011-04-05inotify: fix double free/corruption of stuct userEric Paris2-26/+14
On an error path in inotify_init1 a normal user can trigger a double free of struct user. This is a regression introduced by a2ae4cc9a16e ("inotify: stop kernel memory leak on file creation failure"). We fix this by making sure that if a group exists the user reference is dropped when the group is cleaned up. We should not explictly drop the reference on error and also drop the reference when the group is cleaned up. The new lifetime rules are that an inotify group lives from inotify_new_group to the last fsnotify_put_group. Since the struct user and inotify_devs are directly tied to this lifetime they are only changed/updated in those two locations. We get rid of all special casing of struct user or user->inotify_devs. Signed-off-by: Eric Paris <eparis@redhat.com> Cc: stable@kernel.org (2.6.37 and up) Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-04-05UBIFS: fix debugging failure in dbg_check_space_infoArtem Bityutskiy1-5/+36
This patch fixes a debugging failure with which looks like this: UBIFS error (pid 32313): dbg_check_space_info: free space changed from 6019344 to 6022654 The reason for this failure is described in the comment this patch adds to the code. But in short - 'c->freeable_cnt' may be different before and after re-mounting, and this is normal. So the debugging code should make sure that free space calculations do not depend on 'c->freeable_cnt'. A similar issue has been reported here: http://lists.infradead.org/pipermail/linux-mtd/2011-April/034647.html This patch should fix it. For the -stable guys: this patch is only relevant for kernels 2.6.30 onwards. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Cc: stable@kernel.org [2.6.30+]
2011-04-05UBIFS: fix error path in dbg_debugfs_init_fsArtem Bityutskiy1-5/+5
The debug interface is substandard and on error returns either NULL or an error code packed in the pointer. So using "IS_ERR" for the pointers returned by debugfs function is incorrect. Instead, we should use IS_ERR_OR_NULL. This path is an improved vestion of the original patch from Phil Carmody.

This is just a small clean-up patch which simlifies and unifies the error path in the dbg_debugfs_init_fs().

2011-04-05UBIFS: do not select KALLSYMS_ALLArtem Bityutskiy1-1/+1
All UBIFS needs is to make sure we stacktraces when UBIFS debugging is enabled. It is enough to select KALLSYMS for this, KALLSYMS_ALL is not necessary. Moreover, Randy Dunlap reported that UBIFS causes the following Kconfig dependency warning: warning: (UBIFS_FS_DEBUG && LOCKDEP && LATENCYTOP) selects KALLSYMS_ALL which has unmet direct dependencies (DEBUG_KERNEL && KALLSYMS) The reason is that KALLSYMS_ALL requires DEBUG_KERNEL and KALLSYMS, so ideally, to select KALLSYMS_ALL we'd need to select DEBUG_KERNEL and KALLSYMS first. This seems to be too much to select. The easiest way to go is to forget about KALLSYMS_ALL and just select KALLSYMS when UBIFS debugging is enabled - that should be enough for stackdumps.

2011-04-05Btrfs: don't warn in btrfs_add_orphanJosef Bacik1-2/+0
When I moved the orphan adding to btrfs_truncate I missed the fact that during orphan cleanup we just add the orphan items to the orphan list without going through btrfs_orphan_add, which results in lots of warnings on mount if you have any orphan items that need to be truncated.

2011-04-05Btrfs: fix free space cache when there are pinned extents and clusters V2Josef Bacik1-4/+78
I noticed a huge problem with the free space cache that was presenting as an early ENOSPC. Turns out when writing the free space cache out I forgot to take into account pinned extents and more importantly clusters. This would result in us leaking free space everytime we unmounted the filesystem and remounted it. I fix this by making sure to check and see if the current block group has a cluster and writing out any entries that are in the cluster to the cache, as well as writing any pinned extents we currently have to the cache since those will be available for us to use the next time the fs mounts. This patch also adds a check to the end of load_free_space_cache to make sure we got the right amount of free space cache, and if not make sure to clear the cache and re-cache the old fashioned way.

2011-04-05Btrfs: Fix uninitialized root flags for subvolumesLi Zefan5-1/+30
root_item->flags and root_item->byte_limit are not initialized when a subvolume is created. This bug is not revealed until we added readonly snapshot support - now you mount a btrfs filesystem and you may find the subvolumes in it are readonly. To work around this problem, we steal a bit from root_item->inode_item->flags, and use it to indicate if those fields have been properly initialized. When we read a tree root from disk, we check if the bit is set, and if not we'll set the flag and initialize the two fields of the root item.

2011-04-01quota: Don't write quota info in dquot_commit()Jan Kara1-9/+4
There's no reason to write quota info in dquot_commit(). The writing is a relict from the old days when we didn't have dquot_acquire() and dquot_release() and thus dquot_commit() could have created / removed quota structures from the file. These days dquot_commit() only updates usage counters / limits in quota structure and thus there's no need to write quota info. This also fixes an issue with journaling filesystem which didn't reserve enough space in the transaction for write of quota info (it could have been dirty at the time of dquot_commit() because of a race with other operation changing it).

2011-03-30nilfs2: fix data loss in mmap page write for hole blocksRyusuke Konishi1-6/+5
From the result of a function test of mmap, mmap write to shared pages turned out to be broken for hole blocks. It doesn't write out filled blocks and the data will be lost after umount. This is due to a bug that the target file is not queued for log writer when filling hole blocks. Also, nilfs_page_mkwrite function exits normal code path even after successfully filled hole blocks due to a change of block_page_mkwrite function; just after nilfs was merged into the mainline, block_page_mkwrite() started to return VM_FAULT_LOCKED instead of zero by the patch "mm: close page_mkwrite races" (commit: b827e496c893de0c). The current nilfs_page_mkwrite() is not handling this value properly. This corrects nilfs_page_mkwrite() and will resolve the data loss problem in mmap write.

2011-03-28Treat writes as new when holes span across page boundariesGoldwyn Rodrigues1-0/+6
When a hole spans across page boundaries, the next write forces a read of the block. This could end up reading existing garbage data from the disk in ocfs2_map_page_blocks. This leads to non-zero holes. In order to avoid this, mark the writes as new when the holes span across page boundaries.

2011-03-28btrfs: fix possible deadlock by clearing __GFP_FS flagMiao Xie2-1/+4
Using the GFP_HIGHUSER_MOVABLE flag to allocate the metadata's page may cause deadlock. Task1 open() ... btrfs_search_slot() ... btrfs_cow_block() ... alloc_page() wait for reclaiming shrink_slab() ... shrink_icache_memory() ... btrfs_evict_inode() ... btrfs_search_slot() If the path is locked by task1, the deadlock happens. So the btree's page cache is different with the file's page cache, it can not allocate pages by GFP_HIGHUSER_MOVABLE flag, we must clear __GFP_FS flag in GFP_HIGHUSER_MOVABLE flag.

2011-03-28btrfs: don't mess with i_nlink of unlocked inode in rename()Al Viro1-11/+25
old_inode is not locked; it's not safe to play with its link count. Instead of bumping it and calling btrfs_unlink_inode(), add a variant of the latter that does not do btrfs_drop_nlink()/ btrfs_update_inode(), call it instead of btrfs_inc_nlink()/ btrfs_unlink_inode() and do btrfs_update_inode() ourselves.
