[PATCH v5 0/4] s390/vfio-ap: Fix pre-existing bugs in vfio_ap device driver

Posted by Anthony Krowiak 3 weeks, 4 days ago

The sashiko AI reported several pre-existing bugs in the vfio_ap device
driver code while reviewing unrelated patches. This series fixes four
such bugs.

Change log v4 => v5:
~~~~~~~~~~~~~~~~~~~
Patch 1/4: Fix leak of pinned NIB and registered NISC in vfio_ap_irq_enable
* Fixed bug in vfio_ap_irq_enable() whereby the AQIC resources are freed
  when vfio_ap_wait_for_irq_state() returns false.

Patch 3/4: Fix unbounded loop in apq_reset_check()
* Refactored apq_status_check() to verify the queue was zeroized.
