[PATCH v4 0/3] xen/events: bug fixes and some diagnostic aids

From: Juergen Gross
Date: Sat Mar 06 2021 - 11:19:40 EST


Those are fixes for XSA-332.

The rest of the V3 patches have been applied already. There is one
additional fix in patch 2 which addresses network outages when a guest
is doing reboot loops.

Juergen Gross (3):
xen/events: reset affinity of 2-level event when tearing it down
xen/events: don't unmask an event channel when an eoi is pending
xen/events: avoid handling the same event on two cpus at the same time
