When doing a fsync with a fast path we have a time window where we can miss the fact that writeback of some file data failed, and therefore we endup returning success (0) from fsync when we should return an error. The steps that lead to this are the following: 1) We start all ordered extents by calling filemap_fdatawrite_range(); 2) We do some other work like locking the inode's i_mutex, start a transaction, start a log transaction, etc; 3) We enter btrfs_log_inode(), acquire the inode's log_mutex and collect all the ordered extents from inode's ordered tree into a list; 4) But by the time we do ordered extent collection, some ordered extents we started at step 1) might have already completed with an error, and therefore we didn't found them in the ordered tree and had no idea they finished with an error. This makes our fsync return success (0) to userspace, but has no bad effects on the log like for example insertion of file extent items into the log that point to unwritten extents, because the invalid extent maps were removed before the ordered extent completed (in inode.c:btrfs_finish_ordered_io). So after collecting the ordered extents just check if the inode's i_mapping has any error flags set (AS_EIO or AS_ENOSPC) and leave with an error if it does. Whenever writeback fails for a page of an ordered extent, we call mapping_set_error (done in extent_io.c:end_extent_writepage, called by extent_io.c:end_bio_extent_writepage) that sets one of those error flags in the inode's i_mapping flags. This change also has the side effect of fixing the issue where for fast fsyncs we never checked/cleared the error flags from the inode's i_mapping flags, which means that a full fsync performed after a fast fsync could get such errors that belonged to the fast fsync - because the full fsync calls btrfs_wait_ordered_range() which calls filemap_fdatawait_range(), and the later checks for and clears those flags, while for fast fsyncs we never call filemap_fdatawait_range() or anything else that checks for and clears the error flags from the inode's i_mapping.

If an error happens during writeback of log btree extents, make sure the error is returned to the caller (fsync), so that it takes proper action (commit current transaction) instead of writing a superblock that points to log btrees with all or some nodes that weren't durably persisted.

We use the modified list to keep track of which extents have been modified so we know which ones are candidates for logging at fsync() time. Newly modified extents are added to the list at modification time, around the same time the ordered extent is created. We do this so that we don't have to wait for ordered extents to complete before we know what we need to log. The problem is when something like this happens log extent 0-4k on inode 1 copy csum for 0-4k from ordered extent into log sync log commit transaction log some other extent on inode 1 ordered extent for 0-4k completes and adds itself onto modified list again log changed extents see ordered extent for 0-4k has already been logged at this point we assume the csum has been copied sync log crash On replay we will see the extent 0-4k in the log, drop the original 0-4k extent which is the same one that we are replaying which also drops the csum, and then we won't find the csum in the log for that bytenr. This of course causes us to have errors about not having csums for certain ranges of our inode. So remove the modified list manipulation in unpin_extent_cache, any modified extents should have been added well before now, and we don't want them re-logged. This fixes my test that I could reliably reproduce this problem with. Thanks, cc: stable@vger.kernel.org Signed-off-by:

Liu Bo pointed out that my previous fix would lose the generation update in the scenario I described. It is actually much worse than that, we could lose the entire extent if we lose power right after the transaction commits. Consider the following write extent 0-4k log extent in log tree commit transaction < power fail happens here ordered extent completes We would lose the 0-4k extent because it hasn't updated the actual fs tree, and the transaction commit will reset the log so it isn't replayed. If we lose power before the transaction commit we are save, otherwise we are not. Fix this by keeping track of all extents we logged in this transaction. Then when we go to commit the transaction make sure we wait for all of those ordered extents to complete before proceeding. This will make sure that if we lose power after the transaction commit we still have our data. This also fixes the problem of the improperly updated extent generation.

If we have two fsync()'s race on different subvols one will do all of its work to get into the log_tree, wait on it's outstanding IO, and then allow the log_tree to finish it's commit. The problem is we were just free'ing that subvols logged extents instead of waiting on them, so whoever lost the race wouldn't really have their data on disk. Fix this by waiting properly instead of freeing the logged extents. Thanks, cc: stable@vger.kernel.org Signed-off-by:

This can be reproduced by fstests: btrfs/070 The scenario is like the following: replace worker thread defrag thread --------------------- ------------- copy_nocow_pages_worker btrfs_defrag_file copy_nocow_pages_for_inode ... btrfs_writepages |A| lock_extent_bits extent_write_cache_pages |B| lock_page __extent_writepage ... writepage_delalloc find_lock_delalloc_range |B| lock_extent_bits find_or_create_page pagecache_get_page |A| lock_page This leads to an ABBA pattern deadlock. To fix it, o we just change it to an AABB pattern which means to @unlock_extent_bits() before we @lock_page(), and in this way the @extent_read_full_page_nolock() is no longer in an locked context, so change it back to @extent_read_full_page() to regain protection. o Since we @unlock_extent_bits() earlier, then before @write_page_nocow(), the extent may not really point at the physical block we want, so we have to check it before write.

Replacing a xattr consists of doing a lookup for its existing value, delete the current value from the respective leaf, release the search path and then finally insert the new value. This leaves a time window where readers (getxattr, listxattrs) won't see any value for the xattr. Xattrs are used to store ACLs, so this has security implications. This change also fixes 2 other existing issues which were: *) Deleting the old xattr value without verifying first if the new xattr will fit in the existing leaf item (in case multiple xattrs are packed in the same item due to name hash collision); *) Returning -EEXIST when the flag XATTR_CREATE is given and the xattr doesn't exist but we have have an existing item that packs muliple xattrs with the same name hash as the input xattr. In this case we should return ENOSPC. A test case for xfstests follows soon. Thanks to Alexandre Oliva for reporting the non-atomicity of the xattr replace implementation. Reported-by:

We try to allocate an extent state structure before acquiring the extent state tree's spinlock as we might need a new one later and therefore avoid doing later an atomic allocation while holding the tree's spinlock. However we returned -ENOMEM if that initial non-atomic allocation failed, which is a bit excessive since we might end up not needing the pre-allocated extent state at all - for the case where the tree doesn't have any extent states that cover the input range and cover too any other range. Therefore don't return -ENOMEM if that pre-allocation fails. Signed-off-by:

Our gluster boxes get several thousand statfs() calls per second, which begins to suck hardcore with all of the lock contention on the chunk mutex and dev list mutex. We don't really need to hold these things, if we have transient weirdness with statfs() because of the chunk allocator we don't care, so remove this locking. We still need the dev_list lock if you mount with -o alloc_start however, which is a good argument for nuking that thing from orbit, but that's a patch for another day. Thanks, Signed-off-by:

Josef Bacik authored
Our gluster boxes were spending lots of time in statfs because our fs'es are huge. The problem is statfs loops through all of the block groups looking for read only block groups, and when you have several terabytes worth of data that ends up being a lot of block groups. Move the read only block groups onto a read only list and only proces that list in btrfs_account_ro_block_groups_free_space to reduce the amount of churn. Thanks, Signed-off-by:

The xfstest btrfs/014 which tests the balance operation caused issues with the check_int module. The attempt was made to use btrfs_map_block() to find the physical location for a written block. However, this was not at all needed since the location of the written block was known since a hook to submit_bio() was the reason for entering the check_int module. Additionally, after a block relocation it happened that btrfs_map_block() failed causing misleading error messages afterwards. This patch changes the check_int module to use the known information of the physical location from the bio. Reported-by:

We try to allocate an extent state before acquiring the tree's spinlock just in case we end up needing to split an existing extent state into two. If that allocation failed, we would return -ENOMEM. However, our only single caller (transaction/log commit code), passes in an extent state that was cached from a call to find_first_extent_bit() and that has a very high chance to match exactly the input range (always true for a transaction commit and very often, but not always, true for a log commit) - in this case we end up not needing at all that initial extent state used for an eventual split. Therefore just don't return -ENOMEM if we can't allocate the temporary extent state, since we might not need it at all, and if we end up needing one, we'll do it later anyway. Signed-off-by:

Filipe Manana authored
Right now the only caller of find_first_extent_bit() that is interested in caching extent states (transaction or log commit), never gets an extent state cached. This is because find_first_extent_bit() only caches states that have at least one of the flags EXTENT_IOBITS or EXTENT_BOUNDARY, and the transaction/log commit caller always passes a tree that doesn't have ever extent states with any of those flags (they can only have one of the following flags: EXTENT_DIRTY, EXTENT_NEW or EXTENT_NEED_WAIT). This change together with the following one in the patch series (titled "Btrfs: avoid returning -ENOMEM in convert_extent_bit() too early") will help reduce significantly the chances of calls to convert_extent_bit() fail with -ENOMEM when called from the transaction/log commit code.

When committing a transaction or a log, we look for btree extents that need to be durably persisted by searching for ranges in a io tree that have some bits set (EXTENT_DIRTY or EXTENT_NEW). We then attempt to clear those bits and set the EXTENT_NEED_WAIT bit, with calls to the function convert_extent_bit, and then start writeback for the extents. That function however can return an error (at the moment only -ENOMEM is possible, specially when it does GFP_ATOMIC allocation requests through alloc_extent_state_atomic) - that means the ranges didn't got the EXTENT_NEED_WAIT bit set (or at least not for the whole range), which in turn means a call to btrfs_wait_marked_extents() won't find those ranges for which we started writeback, causing a transaction commit or a log commit to persist a new superblock without waiting for the writeback of extents in that range to finish first. Therefore if a crash happens after persisting the new superblock and before writeback finishes, we have a superblock pointing to roots that weren't fully persisted or roots that point to nodes or leafs that weren't fully persisted, causing all sorts of unexpected/bad behaviour as we endup reading garbage from disk or the content of some node/leaf from a past generation that got cowed or deleted and is no longer valid (for this later case we end up getting error messages like "parent transid verify failed on X wanted Y found Z" when reading btree nodes/leafs from disk).

If cow_file_range_inline() failed, when called from compress_file_range(), we were tagging the locked page for writeback, end its writeback and unlock it, but not marking it with an error nor setting AS_EIO in inode's mapping flags. This made it impossible for a caller of filemap_fdatawrite_range (writepages) or filemap_fdatawait_range() to know that an error happened. And the return value of compress_file_range() is useless because it's returned to a workqueue task and not to the task calling filemap_fdatawrite_range (writepages). This change applies on top of the previous patchset starting at the patch titled: "[1/5] Btrfs: set page and mapping error on compressed write failure" Which changed extent_clear_unlock_delalloc() to use SetPageError and mapping_set_error().

For compressed writes, after doing the first filemap_fdatawrite_range() we don't get the pages tagged for writeback immediately. Instead we create a workqueue task, which is run by other kthread, and keep the pages locked. That other kthread compresses data, creates the respective ordered extent/s, tags the pages for writeback and unlocks them. Therefore we need a second call to filemap_fdatawrite_range() if we have compressed writes, as this second call will wait for the pages to become unlocked, then see they became tagged for writeback and finally wait for the writeback to finish.

Reason is that compress have a max limit pages every time(128K), if a 132k write in, it will be splitted into two write(128k+4k), this bug is a leftover for commit 68bb462d(Btrfs: don't compress for a small write) Fix this problem by checking every time before compression, if it is a small write(<=blocksize), we bail out and fall into nocompression directly.

Our compressed bio write end callback was essentially ignoring the error parameter. When a write error happens, it must pass a value of 0 to the inode's write_page_end_io_hook callback, SetPageError on the respective pages and set AS_EIO in the inode's mapping flags, so that a call to filemap_fdatawait_range() / filemap_fdatawait() can find out that errors happened (we surely don't want silent failures on fsync for example).
