Please pull a handful of random fixes. Details in the tag and changelogs. The following changes since commit 47ac09b91befbb6a235ab620c32af719f8208399: Linux 6.11-rc4 (2024-08-18 13:17:27 -0700) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-fixes-6.11-rcN for you to fetch changes up to 5fa9f0480c7985e44e6ec32def0a395b768599cc: KVM: SEV: Update KVM_AMD_SEV Kconfig entry and mention SEV-SNP (2024-08-28 05:46:25 -0700) ---------------------------------------------------------------- KVM x86 fixes for 6.11 - Fixup missed comments from the REMOVED_SPTE=>FROZEN_SPTE rename. - Ensure a root is successfully loaded when pre-faulting SPTEs. - Grab kvm->srcu when handling KVM_SET_VCPU_EVENTS to guard against accessing memslots if toggling SMM happens to force a VM-Exit. - Emulate MSR_{FS,GS}_BASE on SVM even though interception is always disabled, so that KVM does the right thing if KVM's emulator encounters {RD,WR}MSR. - Explicitly clear BUS_LOCK_DETECT from KVM's caps on AMD, as KVM doesn't yet virtualize BUS_LOCK_DETECT on AMD. - Cleanup the help message for CONFIG_KVM_AMD_SEV, and call out that KVM now supports SEV-SNP too. ---------------------------------------------------------------- Maxim Levitsky (1): KVM: SVM: fix emulation of msr reads/writes of MSR_FS_BASE and MSR_GS_BASE Ravi Bangoria (1): KVM: SVM: Don't advertise Bus Lock Detect to guest if SVM support is missing Sean Christopherson (2): KVM: x86/mmu: Check that root is valid/loaded when pre-faulting SPTEs KVM: x86: Acquire kvm->srcu when handling KVM_SET_VCPU_EVENTS Vitaly Kuznetsov (1): KVM: SEV: Update KVM_AMD_SEV Kconfig entry and mention SEV-SNP Yan Zhao (1): KVM: x86/mmu: Fixup comments missed by the REMOVED_SPTE=>FROZEN_SPTE rename arch/x86/kvm/Kconfig | 6 ++++-- arch/x86/kvm/mmu/mmu.c | 4 +++- arch/x86/kvm/mmu/spte.c | 6 +++--- arch/x86/kvm/mmu/spte.h | 2 +- arch/x86/kvm/mmu/tdp_mmu.c | 8 ++++---- arch/x86/kvm/svm/svm.c | 15 +++++++++++++++ arch/x86/kvm/x86.c | 2 ++ 7 files changed, 32 insertions(+), 11 deletions(-)
