btrfs: start transaction in btrfs_ioctl_setflags() · ff9fef55

Anand Jain authored Apr 20, 2019

Inode attribute can be set through the FS_IOC_SETFLAGS ioctl.  This
flags also includes compression attribute for which we would set/reset
the compression extended attribute. While doing this there is a bit of
duplicate code, the following things happens twice:

- start/end_transaction
- inode_inc_iversion()
- current_time update to inode->i_ctime
- and btrfs_update_inode()

These are updated both at btrfs_ioctl_setflags() and btrfs_set_props()
as well.  This patch merges these two duplicate codes at
btrfs_ioctl_setflags().

btrfs: export btrfs_set_prop · cd31af15

Anand Jain authored Apr 20, 2019

Make btrfs_set_prop() a non-static function, so that it can be called
from btrfs_ioctl_setflags(). We need btrfs_set_prop() instead of
btrfs_set_prop_trans() so that we can use the transaction which is
already started in the current thread.

btrfs: ctree: Dump the leaf before BUG_ON in btrfs_set_item_key_safe · 7c15d410

Qu Wenruo authored Apr 25, 2019

We have a long standing problem with reversed keys that's detected by
btrfs_set_item_key_safe. This is hard to reproduce so we'd like to
capture more information for later analysis.

Let's dump the leaf content before triggering BUG_ON() so that we can
have some clue on what's going wrong.  The output of tree locks should
help us to debug such problem.

Btrfs: improve performance on fsync of files with multiple hardlinks · b8aa330d

Filipe Manana authored Apr 17, 2019

Commit 41bd6067 ("Btrfs: fix fsync of files with multiple hard links
in new directories") introduced a path that makes fsync fallback to a full
transaction commit in order to avoid losing hard links and new ancestors
of the fsynced inode. That path is triggered only when the inode has more
than one hard link and either has a new hard link created in the current
transaction or the inode was evicted and reloaded in the current
transaction.

That path ends up getting triggered very often (hundreds of times) during
the course of pgbench benchmarks, resulting in performance drops of about
20%.

This change restores the performance by not triggering the full transaction
commit in those cases, and instead iterate the fs/subvolume tree in search
of all possible new ancestors, for all hard links, to log them.

Btrfs: fix race between send and deduplication that lead to failures and crashes · 62d54f3a

Filipe Manana authored Apr 22, 2019

Send operates on read only trees and expects them to never change while it
is using them. This is part of its initial design, and this expection is
due to two different reasons:

1) When it was introduced, no operations were allowed to modifiy read-only
   subvolumes/snapshots (including defrag for example).

2) It keeps send from having an impact on other filesystem operations.
   Namely send does not need to keep locks on the trees nor needs to hold on
   to transaction handles and delay transaction commits. This ends up being
   a consequence of the former reason.

However the deduplication feature was introduced later (on September 2013,
while send was introduced in July 2012) and it allowed for deduplication
with destination files that belong to read-only trees (subvolumes and
snapshots).

That means that having a send operation (either full or incremental) running
in parallel with a deduplication that has the destination inode in one of
the trees used by the send operation, can result in tree nodes and leaves
getting freed and reused while send is using them. This problem is similar
to the problem solved for the root nodes getting freed and reused when a
snapshot is made against one tree that is currenly being used by a send
operation, fixed in commits [1] and [2]. These commits explain in detail
how the problem happens and the explanation is valid for any node or leaf
that is not the root of a tree as well. This problem was also discussed
and explained recently in a thread [3].

The problem is very easy to reproduce when using send with large trees
(snapshots) and just a few concurrent deduplication operations that target
files in the trees used by send. A stress test case is being sent for
fstests that triggers the issue easily. The most common error to hit is
the send ioctl return -EIO with the following messages in dmesg/syslog:

 [1631617.204075] BTRFS error (device sdc): did not find backref in send_root. inode=63292, offset=0, disk_byte=5228134400 found extent=5228134400
 [1631633.251754] BTRFS error (device sdc): parent transid verify failed on 32243712 wanted 24 found 27

The first one is very easy to hit while the second one happens much less
frequently, except for very large trees (in that test case, snapshots
with 100000 files having large xattrs to get deep and wide trees).
Less frequently, at least one BUG_ON can be hit:

That BUG_ON happens because while send is using a node, that node is COWed
by a concurrent deduplication, gets freed and gets reused as a leaf (because
a transaction commit happened in between), so when it attempts to read a
slot from the extent buffer, at ctree.c:read_node_slot(), the extent buffer
contents were wiped out and it now matches a leaf (which can even belong to
some other tree now), hitting the BUG_ON(level == 0).

Fix this concurrency issue by not allowing send and deduplication to run
in parallel if both operate on the same readonly trees, returning EAGAIN
to user space and logging an exlicit warning in dmesg/syslog.

Btrfs: send, flush dellaloc in order to avoid data loss · 9f89d5de

Filipe Manana authored Apr 15, 2019

When we set a subvolume to read-only mode we do not flush dellaloc for any
of its inodes (except if the filesystem is mounted with -o flushoncommit),
since it does not affect correctness for any subsequent operations - except
for a future send operation. The send operation will not be able to see the
delalloc data since the respective file extent items, inode item updates,
backreferences, etc, have not hit yet the subvolume and extent trees.

Effectively this means data loss, since the send stream will not contain
any data from existing delalloc. Another problem from this is that if the
writeback starts and finishes while the send operation is in progress, we
have the subvolume tree being being modified concurrently which can result
in send failing unexpectedly with EIO or hitting runtime errors, assertion
failures or hitting BUG_ONs, etc.

Simple reproducer:

  $ mkfs.btrfs -f /dev/sdb
  $ mount /dev/sdb /mnt

  $ btrfs subvolume create /mnt/sv
  $ xfs_io -f -c "pwrite -S 0xea 0 108K" /mnt/sv/foo

  $ btrfs property set /mnt/sv ro true
  $ btrfs send -f /tmp/send.stream /mnt/sv

  $ od -t x1 -A d /mnt/sv/foo
  0000000 ea ea ea ea ea ea ea ea ea ea ea ea ea ea ea ea
  *
  0110592

  $ umount /mnt
  $ mkfs.btrfs -f /dev/sdc
  $ mount /dev/sdc /mnt

  $ btrfs receive -f /tmp/send.stream /mnt
  $ echo $?
  0
  $ od -t x1 -A d /mnt/sv/foo
  0000000
  # ---> empty file

Since this a problem that affects send only, fix it in send by flushing
dellaloc for all the roots used by the send operation before send starts
to process the commit roots.

This is a problem that affects send since it was introduced (commit
31db9f7c ("Btrfs: introduce BTRFS_IOC_SEND for btrfs send/receive"))
but backporting it to older kernels has some dependencies:

- For kernels between 3.19 and 4.20, it depends on commit 3cd24c69
  ("btrfs: use tagged writepage to mitigate livelock of snapshot") because
  the function btrfs_start_delalloc_snapshot() does not exist before that
  commit. So one has to either pick that commit or replace the calls to
  btrfs_start_delalloc_snapshot() in this patch with calls to
  btrfs_start_delalloc_inodes().

- For kernels older than 3.19 it also requires commit e5fa8f86
  ("Btrfs: ensure send always works on roots without orphans") because
  it depends on the function ensure_commit_roots_uptodate() which that
  commits introduced.

- No dependencies for 5.0+ kernels.

A test case for fstests follows soon.

Btrfs: do not start a transaction during fiemap · 03628cdb

Filipe Manana authored Apr 15, 2019

During fiemap, for regular extents (non inline) we need to check if they
are shared and if they are, set the shared bit. Checking if an extent is
shared requires checking the delayed references of the currently running
transaction, since some reference might have not yet hit the extent tree
and be only in the in-memory delayed references.

However we were using a transaction join for this, which creates a new
transaction when there is no transaction currently running. That means
that two more potential failures can happen: creating the transaction and
committing it. Further, if no write activity is currently happening in the
system, and fiemap calls keep being done, we end up creating and
committing transactions that do nothing.

In some extreme cases this can result in the commit of the transaction
created by fiemap to fail with ENOSPC when updating the root item of a
subvolume tree because a join does not reserve any space, leading to a
trace like the following:

Since fiemap (and btrfs_check_shared()) is a read-only operation, do not do
a transaction join to avoid the overhead of creating a new transaction (if
there is currently no running transaction) and introducing a potential
point of failure when the new transaction gets committed, instead use a
transaction attach to grab a handle for the currently running transaction
if any.
