Описание

In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix deadlock between quota disable and qgroup rescan worker

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
