Thank you!
Linus, The following changes since commit 841c35169323cd833294798e58b9bf63fa4fa1de: Linux 6.8-rc4 (2024-02-11 12:18:13 -0800) 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 9895ceeb5cd61092f147f8d611e2df575879dd6f: Merge tag 'kvmarm-fixes-6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD (2024-02-16 12:02:38 -0500) This pull request is mostly a mix of cleanups and fixes in the KVM selftests, but there are also some small arch/ changes. Paolo ---------------------------------------------------------------- ARM: * Avoid dropping the page refcount twice when freeing an unlinked page-table subtree. * Don't source the VFIO Kconfig twice * Fix protected-mode locking order between kvm and vcpus RISC-V: * Fix steal-time related sparse warnings x86: * Cleanup gtod_is_based_on_tsc() to return "bool" instead of an "int" * Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if and only if the incoming events->nmi.pending is non-zero. If the target vCPU is in the UNITIALIZED state, the spurious request will result in KVM exiting to userspace, which in turn causes QEMU to constantly acquire and release QEMU's global mutex, to the point where the BSP is unable to make forward progress. * Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl being incorrectly truncated, and ultimately causes KVM to think a fixed counter has already been disabled (KVM thinks the old value is '0'). * Fix a stack leak in KVM_GET_MSRS where a failed MSR read from userspace that is ultimately ignored due to ignore_msrs=true doesn't zero the output as intended. Selftests cleanups and fixes: * Remove redundant newlines from error messages. * Delete an unused variable in the AMX test (which causes build failures when compiling with -Werror). * Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails with an error code other than ENOENT (a Hyper-V selftest bug resulted in an EMFILE, and the test eventually got skipped). * Fix TSC related bugs in several Hyper-V selftests. * Fix a bug in the dirty ring logging test where a sem_post() could be left pending across multiple runs, resulting in incorrect synchronization between the main thread and the vCPU worker thread. * Relax the dirty log split test's assertions on 4KiB mappings to fix false positives due to the number of mappings for memslot 0 (used for code and data that is NOT being dirty logged) changing, e.g. due to NUMA balancing. ---------------------------------------------------------------- Andrew Jones (8): KVM: selftests: Remove redundant newlines KVM: selftests: aarch64: Remove redundant newlines KVM: selftests: riscv: Remove redundant newlines KVM: selftests: s390x: Remove redundant newlines KVM: selftests: x86_64: Remove redundant newlines RISC-V: paravirt: steal_time should be static RISC-V: paravirt: Use correct restricted types RISC-V: KVM: Use correct restricted types Masahiro Yamada (1): KVM: arm64: Do not source virt/lib/Kconfig twice Mathias Krause (1): KVM: x86: Fix KVM_GET_MSRS stack info leak Mingwei Zhang (1): KVM: x86/pmu: Fix type length error when reading pmu->fixed_ctr_ctrl Paolo Bonzini (5): Merge tag 'kvm-x86-fixes-6.8-rcN' of https://github.com/kvm-x86/linux into HEAD Merge tag 'kvm-x86-selftests-6.8-rcN' of https://github.com/kvm-x86/linux into HEAD Merge tag 'kvm-riscv-fixes-6.8-1' of https://github.com/kvm-riscv/linux into HEAD Merge tag 'kvmarm-fixes-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD Merge tag 'kvmarm-fixes-6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD Prasad Pandit (1): KVM: x86: make KVM_REQ_NMI request iff NMI pending for vcpu Sean Christopherson (4): KVM: selftests: Reword the NX hugepage test's skip message to be more helpful KVM: selftests: Delete superfluous, unused "stage" variable in AMX test KVM: selftests: Fix a semaphore imbalance in the dirty ring logging test KVM: selftests: Don't assert on exact number of 4KiB in dirty log split test Sebastian Ene (1): KVM: arm64: Fix circular locking dependency Vitaly Kuznetsov (7): KVM: selftests: Avoid infinite loop in hyperv_features when invtsc is missing KVM: selftests: Fail tests when open() fails with !ENOENT KVM: selftests: Generalize check_clocksource() from kvm_clock_test KVM: selftests: Use generic sys_clocksource_is_tsc() in vmx_nested_tsc_scaling_test KVM: selftests: Run clocksource dependent tests with hyperv_clocksource_tsc_page too KVM: selftests: Make hyperv_clock require TSC based system clocksource KVM: x86: Make gtod_is_based_on_tsc() return 'bool' Will Deacon (1): KVM: arm64: Fix double-free following kvm_pgtable_stage2_free_unlinked() arch/arm64/kvm/Kconfig | 1 -
