Subject: [PATCH 6.1 130/181] btrfs: fix deadlock when aborting transaction during relocation with scrub
Date: Mon, 3 Apr 2023 16:09:25 +0200 [thread overview]
Message-ID: <20230403140419.297215977@linuxfoundation.org> (raw)
In-Reply-To: <20230403140415.090615502@linuxfoundation.org>
From: Filipe Manana <fdmanana@suse.com>
commit 2d82a40aa7d6fcae0250ec68b8566cdee7bfd44c upstream.
Before relocating a block group we pause scrub, then do the relocation and
then unpause scrub. The relocation process requires starting and committing
a transaction, and if we have a failure in the critical section of the
transaction commit path (transaction state >= TRANS_STATE_COMMIT_START),
we will deadlock if there is a paused scrub.
That results in stack traces like the following:
[42.479] BTRFS info (device sdc): relocating block group 53876686848 flags metadata|raid6
[42.936] BTRFS warning (device sdc): Skipping commit of aborted transaction.

What happens is the following:
1) A scrub is running, so fs_info->scrubs_running is 1;
2) Task A starts block group relocation, and at btrfs_relocate_chunk() it
pauses scrub by calling btrfs_scrub_pause(). That increments
fs_info->scrub_pause_req from 0 to 1 and waits for the scrub task to
pause (for fs_info->scrubs_paused to be == to fs_info->scrubs_running);
3) The scrub task pauses at scrub_pause_off(), waiting for
fs_info->scrub_pause_req to decrease to 0;
4) Task A then enters btrfs_relocate_block_group(), and down that call
chain we start a transaction and then attempt to commit it;
5) When task A calls btrfs_commit_transaction(), it either will do the
commit itself or wait for some other task that already started the
commit of the transaction - it doesn't matter which case;
6) The transaction commit enters state TRANS_STATE_COMMIT_START;
7) An error happens during the transaction commit, like -ENOSPC when
running delayed refs or delayed items for example;
8) This results in calling transaction.c:cleanup_transaction(), where
we call btrfs_scrub_cancel(), incrementing fs_info->scrub_cancel_req
from 0 to 1, and blocking this task waiting for fs_info->scrubs_running
to decrease to 0;
9) From this point on, both the transaction commit and the scrub task
hang forever:
1) The transaction commit is waiting for fs_info->scrubs_running to
be decreased to 0;
2) The scrub task is at scrub_pause_off() waiting for
fs_info->scrub_pause_req to decrease to 0 - so it can not proceed
to stop the scrub and decrement fs_info->scrubs_running from 0 to 1.
Therefore resulting in a deadlock.
Fix this by having cleanup_transaction(), called if a transaction commit
fails, not call btrfs_scrub_cancel() if relocation is in progress, and
having btrfs_relocate_block_group() call btrfs_scrub_cancel() instead if
the relocation failed and a transaction abort happened.
This was triggered with btrfs/061 from fstests.
Fixes: 55e3a601c81c ("btrfs: Fix data checksum error cause by replace with io-load.")
