- iavf: Fix reset error handling
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
iavf: Fix reset error handling
Do not call iavfclose in iavfresettask error handling. Doing so can lead to double call of napidisable, which can lead to deadlock there. Removing VF would lead to iavfremove task being stuck, because it requires critlock, which is held by iavfclose. Call iavfdisablevf if reset fail, so that driver will clean up remaining invalid resources. During rapid VF resets, HW can fail to setup VF mailbox. Wrong error handling can lead to iavfremove being stuck with: [ 5218.999087] iavf 0000:82:01.0: Failed to init adminq: -53 ...
