Sean Christopherson b67e7c61c1 KVM: nVMX: Clear IDT vectoring on nested VM-Exit for double/triple fault ... [ Upstream commit 9bd1f0efa8 ] Clear the IDT vectoring field in vmcs12 on next VM-Exit due to a double or triple fault. Per the SDM, a VM-Exit isn't considered to occur during event delivery if the exit is due to an intercepted double fault or a triple fault. Opportunistically move the default clearing (no event "pending") into the helper so that it's more obvious that KVM does indeed handle this case. Note, the double fault case is worded rather wierdly in the SDM: The original event results in a double-fault exception that causes the VM exit directly. Temporarily ignoring injected events, double faults can _only_ occur if an exception occurs while attempting to deliver a different exception, i.e. there's _always_ an original event. And for injected double fault, while there's no original event, injected events are never subject to interception. Presumably the SDM is calling out that a the vectoring info will be valid if a different exit occurs after a double fault, e.g. if a #PF occurs and is intercepted while vectoring #DF, then the vectoring info will show the double fault. In other words, the clause can simply be read as: The VM exit is caused by a double-fault exception.
