Subject: [PATCH 0/5] KVM: x86/mmu: TDP MMU fixes for 6.2
Date: Tue, 13 Dec 2022 03:30:25 +0000 [thread overview]
Message-ID: <20221213033030.83345-1-seanjc@google.com> (raw)
Fix three fatal TDP MMU bugs introduced in 6.2, harden related code,
and clean up kvm_tdp_mmu_map() to eliminate the need for gotos.
Sean Christopherson (5):
KVM: x86/mmu: Don't attempt to map leaf if target TDP MMU SPTE is
frozen
KVM: x86/mmu: Map TDP MMU leaf SPTE iff target level is reached
KVM: x86/mmu: Re-check under lock that TDP MMU SP hugepage is
disallowed
KVM: x86/mmu: Don't install TDP MMU SPTE if SP has unexpected level
KVM: x86/mmu: Move kvm_tdp_mmu_map()'s prolog and epilog to its caller
