charset="UTF-8" Fix a bug where KVM writes more bytes for KVM_GET_NESTED_STATE than it reports in the output size if L1 is active and has a valid shadow VMCS pointer. The bug is all but guaranteed to be benign in practice, as all VMMs I could find that support nested virtualization just preallocate the max buffer size. Sean Christopherson (2): KVM: nVMX: Save shadow VMCS when getting nested state iff L2 is active KVM: selftests: Add regression test for KVM writing but not reporting vmcs12 arch/x86/kvm/vmx/nested.c | 2 +- .../testing/selftests/kvm/lib/x86/processor.c | 6 +++++ tools/testing/selftests/kvm/x86/state_test.c | 24 ++++++++++--------- 3 files changed, 20 insertions(+), 12 deletions(-) base-commit: 164405e8e9a0378c7e1aff2254625a6553a291f1 -- 2.56.0.218.g1ec904b173-goog
