Subject: [PATCH 5.4 10/44] btrfs: fix deadlock between quota disable and qgroup rescan worker
Date: Mon, 7 Feb 2022 12:06:26 +0100 [thread overview]
Message-ID: <20220207103753.491219976@linuxfoundation.org> (raw)
In-Reply-To: <20220207103753.155627314@linuxfoundation.org>
From: Shin'ichiro Kawasaki <shinichiro.kawasaki@wdc.com>
commit e804861bd4e69cc5fe1053eedcb024982dde8e48 upstream.
Quota disable ioctl starts a transaction before waiting for the qgroup
rescan worker completes. However, this wait can be infinite and results
in deadlock because of circular dependency among the quota disable
ioctl, the qgroup rescan worker and the other task with transaction such
as block group relocation task.
The deadlock happens with the steps following:
1) Task A calls ioctl to disable quota. It starts a transaction and
waits for qgroup rescan worker completes.
2) Task B such as block group relocation task starts a transaction and
joins to the transaction that task A started. Then task B commits to
the transaction. In this commit, task B waits for a commit by task A.
3) Task C as the qgroup rescan worker starts its job and starts a
transaction. In this transaction start, task C waits for completion
of the transaction that task A started and task B committed.
This deadlock was found with fstests test case btrfs/115 and a zoned
null_blk device. The test case enables and disables quota, and the
block group reclaim was triggered during the quota disable by chance.
The deadlock was also observed by running quota enable and disable in
parallel with 'btrfs balance' command on regular null_blk devices.
An example report of the deadlock:

[374.126780] =============================================
To avoid the deadlock, wait for the qgroup rescan worker to complete
before starting the transaction for the quota disable ioctl. Clear
BTRFS_FS_QUOTA_ENABLE flag before the wait and the transaction to
request the worker to complete. On transaction start failure, set the
BTRFS_FS_QUOTA_ENABLE flag again. These BTRFS_FS_QUOTA_ENABLE flag
changes can be done safely since the function btrfs_quota_disable is not
called concurrently because of fs_info->subvol_sem.
Also check the BTRFS_FS_QUOTA_ENABLE flag in qgroup_rescan_init to avoid
another qgroup rescan worker to start after the previous qgroup worker
completed.
