[kvm-unit-tests,0/3] Add additional testing for routing L2 exceptions

Message

Aaron Lewis Dec. 9, 2021, 6:26 p.m. UTC

In a previous series testing was added to verify that when a #PF occured
in L2 the exception was routed to the correct place.  In this series
other exceptions are tested (ie: #GP, #UD, #DE, #DB, #BP, #AC).

The first two changes in this series are bug fixes that were discovered
while making these changes.  The last change is the test itself.

Aaron Lewis (3):
  x86: Fix a #GP from occurring in usermode's exception handlers
  x86: Align L2's stacks
  x86: Add test coverage for the routing logic when exceptions occur in
    L2
