Linus, The following changes since commit 59b723cd2adbac2a34fc8e12c74ae26ae45bf230: Linux 6.12-rc6 (2024-11-03 14:05:52 -1000) are available in the Git repository at: https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus for you to fetch changes up to aa0d42cacf093a6fcca872edc954f6f812926a17: KVM: VMX: Bury Intel PT virtualization (guest/host mode) behind CONFIG_BROKEN (2024-11-08 05:57:13 -0500) ---------------------------------------------------------------- KVM x86 and selftests fixes for 6.12: x86: - When emulating a guest TLB flush for a nested guest, flush vpid01, not vpid02, if L2 is active but VPID is disabled in vmcs12, i.e. if L2 and L1 are sharing VPID '0' (from L1's perspective). - Fix a bug in the SNP initialization flow where KVM would return '0' to userspace instead of -errno on failure. - Move the Intel PT virtualization (i.e. outputting host trace to host buffer and guest trace to guest buffer) behind CONFIG_BROKEN. - Fix memory leak on failure of KVM_SEV_SNP_LAUNCH_START - Fix a bug where KVM fails to inject an interrupt from the IRR after KVM_SET_LAPIC. Selftests: - Increase the timeout for the memslot performance selftest to avoid false failures on arm64 and nested x86 platforms. - Fix a goof in the guest_memfd selftest where a for-loop initialized a bit mask to zero instead of BIT(0). - Disable strict aliasing when building KVM selftests to prevent the compiler from treating things like "u64 *" to "uint64_t *" cases as undefined behavior, which can lead to nasty, hard to debug failures. - Force -march=x86-64-v2 for KVM x86 selftests if and only if the uarch is supported by the compiler. - Fix broken compilation of kvm selftests after a header sync in tools/ ---------------------------------------------------------------- Dionna Glaze (1): kvm: svm: Fix gctx page leak on invalid inputs John Sperbeck (1): KVM: selftests: use X86_MEMTYPE_WB instead of VMX_BASIC_MEM_TYPE_WB Maxim Levitsky (1): KVM: selftests: memslot_perf_test: increase guest sync timeout Paolo Bonzini (1): Merge tag 'kvm-x86-fixes-6.12-rcN' of https://github.com/kvm-x86/linux into HEAD Patrick Roy (1): KVM: selftests: fix unintentional noop test in guest_memfd_test.c Sean Christopherson (6): KVM: selftests: Disable strict aliasing KVM: selftests: Don't force -march=x86-64-v2 if it's unsupported KVM: nVMX: Treat vpid01 as current if L2 is active, but with VPID disabled KVM: SVM: Propagate error from snp_guest_req_init() to userspace KVM: x86: Unconditionally set irr_pending when updating APICv state KVM: VMX: Bury Intel PT virtualization (guest/host mode) behind CONFIG_BROKEN arch/x86/kvm/lapic.c | 29 +++++++++++++++--------- arch/x86/kvm/svm/sev.c | 15 ++++++++----- arch/x86/kvm/vmx/nested.c | 30 ++++++++++++++++++++----- arch/x86/kvm/vmx/vmx.c | 6 +++-- tools/testing/selftests/kvm/Makefile | 10 +++++---- tools/testing/selftests/kvm/guest_memfd_test.c | 2 +- tools/testing/selftests/kvm/lib/x86_64/vmx.c | 2 +- tools/testing/selftests/kvm/memslot_perf_test.c | 2 +- 8 files changed, 65 insertions(+), 31 deletions(-)
