Revision 9dba988edb31d013003b7f00e82dd56f01db70c3 authored by Aaron Lewis on 31 May 2019, 14:14:52 UTC, committed by Paolo Bonzini on 19 June 2019, 14:11:54 UTC
When running with /sys/module/kvm_intel/parameters/unrestricted_guest=N,
test that a kernel warning does not occur informing us that
vcpu->mmio_needed=1. This can happen when KVM_RUN is called after a
triple fault.
This test was made to detect a bug that was reported by Syzkaller
(https://groups.google.com/forum/#!topic/syzkaller/lHfau8E3SOE) and
fixed with commit bbeac2830f4de ("KVM: X86: Fix residual mmio emulation
request to userspace").
