2017-02-24Btrfs: do not create explicit holes when replaying log tree if NO_HOLES enabledFilipe Manana1-0/+5
We log holes explicitly by using file extent items, however when replaying a log tree, if a logged file extent item corresponds to a hole and the NO_HOLES feature is enabled we do not need to copy the file extent item into the fs/subvolume tree, as the absence of such file extent items is the purpose of the NO_HOLES feature. So skip the copying of file extent items representing holes when the NO_HOLES feature is enabled. Signed-off-by: Filipe Manana <fdmanana@suse.com>

2017-02-14btrfs: Make btrfs_ino take a struct btrfs_inodeNikolay Borisov1-21/+21
Currently btrfs_ino takes a struct inode and this causes a lot of internal btrfs functions which consume this ino to take a VFS inode, rather than btrfs' own struct btrfs_inode. In order to fix this "leak" of VFS structs into the internals of btrfs first it's necessary to eliminate all uses of struct inode for the purpose of inode. This patch does that by using BTRFS_I to convert an inode to btrfs_inode. With this problem eliminated subsequent patches will start eliminating the passing of struct inode altogether, eventually resulting in a lot cleaner code.

2017-01-03Btrfs: fix lockdep warning about log_mutexLiu Bo1-3/+10
While checking INODE_REF/INODE_EXTREF for a corner case, we may acquire a different inode's log_mutex with holding the current inode's log_mutex, and lockdep has complained this with a possilble deadlock warning. Fix this by using mutex_lock_nested() when processing the other inode's log_mutex.

2016-12-13Merge branch 'for-chris-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/fdmanana/linux into for-linus-4.10Chris Mason1-4/+3
Patches queued up by Filipe: The most important change is still the fix for the extent tree corruption that happens due to balance when qgroups are enabled (a regression introduced in 4.7 by a fix for a regression from the last qgroups rework). This has been hitting SLE and openSUSE users and QA very badly, where transactions keep getting aborted when running delayed references leaving the root filesystem in RO mode and nearly unusable. There are fixes here that allow us to run xfstests again with the integrity checker enabled, which has been impossible since 4.8 (apparently I'm the only one running xfstests with the integrity checker enabled, which is useful to validate dirtied leafs, like checking if there are keys out of order, etc). The rest are just some trivial fixes, most of them tagged for stable, and two cleanups. Signed-off-by: Chris Mason <clm@fb.com>
2016-12-06btrfs: remove root parameter from transaction commit/end routinesJeff Mahoney1-2/+2
Now we only use the root parameter to print the root objectid in a tracepoint. We can use the root parameter from the transaction handle for that. It's also used to join the transaction with async commits, so we remove the comment that it's just for checking.

2016-12-06btrfs: split btrfs_wait_marked_extents into normal and tree log functionsJeff Mahoney1-8/+6
btrfs_write_and_wait_marked_extents and btrfs_sync_log both call btrfs_wait_marked_extents, which provides a core loop and then handles errors differently based on whether it's it's a log root or not. This means that btrfs_write_and_wait_marked_extents needs to take a root because btrfs_wait_marked_extents requires one, even though it's only used to determine whether the root is a log root. The log root code won't ever call into the transaction commit code using a log root, so we can factor out the core loop and provide the error handling appropriate to each waiter in new routines. This allows us to eventually remove the root argument from btrfs_commit_transaction, and as a result, btrfs_end_transaction.

2016-12-06btrfs: take an fs_info directly when the root is not used otherwiseJeff Mahoney1-24/+34

2016-12-06btrfs: pull node/sector/stripe sizes out of root and into fs_infoJeff Mahoney1-5/+7

2016-11-30Btrfs: fix tree search logic when replaying directory entry deletesRobbie Ko1-2/+1
If a log tree has a layout like the following: leaf N: ... item 240 key (282 DIR_LOG_ITEM 0) itemoff 8189 itemsize 8 dir log end 1275809046 leaf N + 1: item 0 key (282 DIR_LOG_ITEM 3936149215) itemoff 16275 itemsize 8 dir log end 18446744073709551615 ... When we pass the value 1275809046 + 1 as the parameter start_ret to the function tree-log.c:find_dir_range() (done by replay_dir_deletes()), we end up with path->slots[0] having the value 239 (points to the last item of leaf N, item 240). Because the dir log item in that position has an offset value smaller than *start_ret (1275809046 + 1) we need to move on to the next leaf, however the logic for that is wrong since it compares the current slot to the number of items in the leaf, which is smaller and therefore we don't lookup for the next leaf but instead we set the slot to point to an item that does not exist, at slot 240, and we later operate on that slot which has unexpected content or in the worst case can result in an invalid memory access (accessing beyond the last page of leaf N's extent buffer). So fix the logic that checks when we need to lookup at the next leaf by first incrementing the slot and only after to check if that slot is beyond the last item of the current leaf.

2016-11-30Btrfs: fix deadlock caused by fsync when logging directory entriesRobbie Ko1-2/+2
While logging new directory entries, at tree-log.c:log_new_dir_dentries(), after we call btrfs_search_forward() we get a leaf with a read lock on it, and without unlocking that leaf we can end up calling btrfs_iget() to get an inode pointer. The later (btrfs_iget()) can end up doing a read-only search on the same tree again, if the inode is not in memory already, which ends up causing a deadlock if some other task in the meanwhile started a write search on the tree and is attempting to write lock the same leaf that btrfs_search_forward() locked while holding write locks on upper levels of the tree blocking the read search from btrfs_iget(). In this scenario we get a deadlock. So fix this by releasing the search path before calling btrfs_iget() at tree-log.c:log_new_dir_dentries().

Pull btrfs fixes from Chris Mason: "My patch fixes the btrfs list_head abuse that we tracked down during Dave Jones' memory corruption investigation. With both Jens and my patches in place, I'm no longer able to trigger problems. Filipe is fixing a difficult old bug between snapshots, balance and send.
