Description

Reapply "drm/qxl: simplify qxl_fence_wait"

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

Reapply "drm/qxl: simplify qxl_fence_wait"

This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea.

Stephen Rostedt reports:

"I went to run my tests on my VMs and the tests hung on boot up.

Unfortunately, the most I ever got out was:

[ 93.607888] Testing event system initcall: OK

[ 93.667730] Running tests on all trace events:

[ 93.669757] Testing all events: OK

[ 95.631064] ------------[ cut here ]------------

Timed out after 60 seconds"

and further debugging points to a possible circular locking dependency

between the console_owner locking and the worker pool locking.

Reverting the commit allows Steve's VM to boot to completion again.

[ This may obviously result in the "[TTM] Buffer eviction failed"

messages again, which was the reason for that original revert. But at

this point this seems preferable to a non-booting system... ]

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
