KVM: nVMX: nEPT injection fixes and cleanups

[PATCH 0/3] KVM: nVMX: nEPT injection fixes and cleanups

Posted by Sean Christopherson 1 year, 10 months ago

Fix a minor bug where KVM doesn't clear EXIT_QUALIFICATION when injecting
an EPT Misconfig into L1, and then move exit_qualification out of
kvm_vcpu_arch to avoid recurrences of the bug fixed by commit d7f0a00e438d
("KVM: VMX: Report up-to-date exit qualification to userspace").

Sean Christopherson (3):
  KVM: nVMX: Clear EXIT_QUALIFICATION when injecting an EPT Misconfig
  KVM: x86: Move nEPT exit_qualification field from kvm_vcpu_arch to
    x86_exception
  KVM: nVMX: Add a sanity check that nested PML Full stems from EPT
    Violations
