Description

In the Linux kernel, the following vulnerability has been resolved:\nReapply 'drm/qxl: simplify qxl_fence_wait'\nThis reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea.\nStephen Rostedt reports:\n'I went to run my tests on my VMs and the tests hung on boot up.\nUnfortunately, the most I ever got out was:\n[ 93.607888] Testing event system initcall: OK\n[ 93.667730] Running tests on all trace events:\n[ 93.669757] Testing all events: OK\n[ 95.631064] ------------[ cut here ]------------\nTimed out after 60 seconds'\nand further debugging points to a possible circular locking dependency\nbetween the console_owner locking and the worker pool locking.\nReverting the commit allows Steve's VM to boot to completion again.\n[ This may obviously result in the '[TTM] Buffer eviction failed'\nmessages again, which was the reason for that original revert. But at\nthis point this seems preferable to a non-booting system... ]
