Subject: [PATCH 5.12 143/161] btrfs: fix fsync failure and transaction abort after writes to prealloc extents
Date: Tue, 8 Jun 2021 20:27:53 +0200 [thread overview]
Message-ID: <20210608175950.286075344@linuxfoundation.org> (raw)
In-Reply-To: <20210608175945.476074951@linuxfoundation.org>
From: Filipe Manana <fdmanana@suse.com>
commit ea7036de0d36c4e6c9508f68789e9567d514333a upstream.
When doing a series of partial writes to different ranges of preallocated
extents with transaction commits and fsyncs in between, we can end up with
a checksum items in a log tree. This causes an fsync to fail with -EIO and
abort the transaction, turning the filesystem to RO mode, when syncing the
log.
For this to happen, we need to have a full fsync of a file following one
or more fast fsyncs.
The following example reproduces the problem and explains how it happens:
$ mkfs.btrfs -f /dev/sdc
$ mount /dev/sdc /mnt
# Create our test file with 2 preallocated extents. Leave a 1M hole
# between them to ensure that we get two file extent items that will
# never be merged into a single one. The extents are contiguous on disk,
# which will later result in the checksums for their data to be merged
# into a single checksum item in the csums btree.
#
$ xfs_io -f \
-c "falloc 0 1M" \
-c "falloc 3M 3M" \
/mnt/foobar
# Now write to the second extent and leave only 1M of it as unwritten,
# which corresponds to the file range [4M, 5M[.
#
# Then fsync the file to flush delalloc and to clear full sync flag from
# the inode, so that a future fsync will use the fast code path.
#
# After the writeback triggered by the fsync we have 3 file extent items
# that point to the second extent we previously allocated:
#
# 1) One file extent item of type BTRFS_FILE_EXTENT_REG that covers the
# file range [3M, 4M[
#
# 2) One file extent item of type BTRFS_FILE_EXTENT_PREALLOC that covers
# the file range [4M, 5M[
#
# 3) One file extent item of type BTRFS_FILE_EXTENT_REG that covers the
# file range [5M, 6M[
#
# All these file extent items have a generation of 6, which is the ID of
# the transaction where they were created. The split of the original file
# extent item is done at btrfs_mark_extent_written() when ordered extents
# complete for the file ranges [3M, 4M[ and [5M, 6M[.
#
$ xfs_io -c "pwrite -S 0xab 3M 1M" \
-c "pwrite -S 0xef 5M 1M" \
-c "fsync" \
/mnt/foobar
# Commit the current transaction. This wipes out the log tree created by
# the previous fsync.
sync
# Now write to the unwritten range of the second extent we allocated,
# corresponding to the file range [4M, 5M[, and fsync the file, which
# triggers the fast fsync code path.
#
# The fast fsync code path sees that there is a new extent map covering
# the file range [4M, 5M[ and therefore it will log a checksum item
# covering the range [1M, 2M[ of the second extent we allocated.
#
# Also, after the fsync finishes we no longer have the 3 file extent
# items that pointed to 3 sections of the second extent we allocated.
# Instead we end up with a single file extent item pointing to the whole
# extent, with a type of BTRFS_FILE_EXTENT_REG and a generation of 7 (the
# current transaction ID). This is due to the file extent item merging we
# do when completing ordered extents into ranges that point to unwritten
# (preallocated) extents. This merging is done at
# btrfs_mark_extent_written().
#
$ xfs_io -c "pwrite -S 0xcd 4M 1M" \
-c "fsync" \
/mnt/foobar
# Now do some write to our file outside the range of the second extent
# that we allocated with fallocate() and truncate the file size from 6M
# down to 5M.
#
# The truncate operation sets the full sync runtime flag on the inode,
# forcing the next fsync to use the slow code path. It also changes the
# length of the second file extent item so that it represents the file
# range [3M, 5M[ and not the range [3M, 6M[ anymore.
#
# Finally fsync the file. Since this is a fsync that triggers the slow
# code path, it will remove all items associated to the inode from the
# log tree and then it will scan for file extent items in the
# fs/subvolume tree that have a generation matching the current
# transaction ID, which is 7. This means it will log 2 file extent
# items:
#
# 1) One for the first extent we allocated, covering the file range
# [0, 1M[
#
# 2) Another for the first 2M of the second extent we allocated,
# covering the file range [3M, 5M[
#
# When logging the first file extent item we log a single checksum item
# that has all the checksums for the entire extent.
#
# When logging the second file extent item, we also lookup for the
# checksums that are associated with the range [0, 2M[ of the second
# extent we allocated (file range [3M, 5M[), and then we log them with
# btrfs_csum_file_blocks(). However that results in ending up with a log
# that has two checksum items with ranges that overlap:
#
# 1) One for the range [1M, 2M[ of the second extent we allocated,
# corresponding to the file range [4M, 5M[, which we logged in the
# previous fsync that used the fast code path;
#
# 2) One for the ranges [0, 1M[ and [0, 2M[ of the first and second
# extents, respectively, corresponding to the files ranges [0, 1M[
# and [3M, 5M[. This one was added during this last fsync that uses
# the slow code path and overlaps with the previous one logged by
# the previous fast fsync.
#
# This happens because when logging the checksums for the second
# extent, we notice they start at an offset that matches the end of the
# checksums item that we logged for the first extent, and because both
# extents are contiguous on disk, btrfs_csum_file_blocks() decides to
# extend that existing checksums item and append the checksums for the
# second extent to this item. The end result is we end up with two
# checksum items in the log tree that have overlapping ranges, as
# listed before, resulting in the fsync to fail with -EIO and aborting
# the transaction, turning the filesystem into RO mode.
#
$ xfs_io -c "pwrite -S 0xff 0 1M" \
-c "truncate 5M" \
-c "fsync" \

fsync: Input/output error
After running the example, dmesg/syslog shows the tree checker complained
about the checksum items with overlapping ranges and we aborted the
transaction:

[756289.637082] BTRFS info (device sdc): forced readonly
Having checksum items covering ranges that overlap is dangerous as in some
cases it can lead to having extent ranges for which we miss checksums
after log replay or getting the wrong checksum item. There were some fixes
in the past for bugs that resulted in this problem, and were explained and
fixed by the following commits:
27b9a8122ff71a ("Btrfs: fix csum tree corruption, duplicate and outdated checksums")
b84b8390d6009c ("Btrfs: fix file read corruption after extent cloning and fsync")
40e046acbd2f36 ("Btrfs: fix missing data checksums after replaying a log tree")
e289f03ea79bbc ("btrfs: fix corrupt log due to concurrent fsync of inodes with shared extents")
Fix the issue by making btrfs_csum_file_blocks() taking into account the
start offset of the next checksum item when it decides to extend an
existing checksum item, so that it never extends the checksum to end at a
range that goes beyond the start range of the next checksum item.
When we can not access the next checksum item without releasing the path,
simply drop the optimization of extending the previous checksum item and
fallback to inserting a new checksum item - this happens rarely and the
optimization is not significant enough for a log tree in order to justify
the extra complexity, as it would only save a few bytes (the size of a
struct btrfs_item) of leaf space.
This behaviour is only needed when inserting into a log tree because
for the regular checksums tree we never have a case where we try to
insert a range of checksums that overlap with a range that was previously
inserted.
A test case for fstests will follow soon.
