Revision 37f66bbef0920429b8cb5eddba849ec4308a9f8e authored by Maxim Levitsky on 27 August 2020, 17:11:44 UTC, committed by Paolo Bonzini on 12 September 2020, 16:22:55 UTC 
KVM: emulator: more strict rsm checks.
 
Don't ignore return values in rsm_load_state_64/32 to avoid
loading invalid state from SMM state area if it was tampered with
by the guest.

This is primarly intended to avoid letting guest set bits in EFER
(like EFER.SVME when nesting is disabled) by manipulating SMM save area.
