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" # # * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (25 commits) # KVM: arm64: Fix double-free following kvm_pgtable_stage2_free_unlinked() # RISC-V: KVM: Use correct restricted types # RISC-V: paravirt: Use correct restricted types # RISC-V: paravirt: steal_time should be static # KVM: selftests: Don't assert on exact number of 4KiB in dirty log split test # KVM: selftests: Fix a semaphore imbalance in the dirty ring logging test # KVM: x86: Fix KVM_GET_MSRS stack info leak # KVM: arm64: Do not source virt/lib/Kconfig twice # KVM: x86/pmu: Fix type length error when reading pmu->fixed_ctr_ctrl # KVM: x86: Make gtod_is_based_on_tsc() return 'bool' # KVM: selftests: Make hyperv_clock require TSC based system clocksource # KVM: selftests: Run clocksource dependent tests with hyperv_clocksource_tsc_page too # KVM: selftests: Use generic sys_clocksource_is_tsc() in vmx_nested_tsc_scaling_test # KVM: selftests: Generalize check_clocksource() from kvm_clock_test # KVM: x86: make KVM_REQ_NMI request iff NMI pending for vcpu # KVM: arm64: Fix circular locking dependency # KVM: selftests: Fail tests when open() fails with !ENOENT # KVM: selftests: Avoid infinite loop in hyperv_features when invtsc is missing # KVM: selftests: Delete superfluous, unused "stage" variable in AMX test # KVM: selftests: x86_64: Remove redundant newlines # ... # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 683b783c2093e0172738f899ba188bc406b0595f # make -s -j 40 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- sun3_defconfig # < make -s -j 40 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 40 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 40 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- In file included from /kisskb/src/include/linux/swab.h:5, from /kisskb/src/include/uapi/linux/byteorder/big_endian.h:14, from /kisskb/src/include/linux/byteorder/big_endian.h:5, from /kisskb/src/arch/m68k/include/uapi/asm/byteorder.h:5, from /kisskb/src/include/asm-generic/bitops/le.h:6, from /kisskb/src/arch/m68k/include/asm/bitops.h:566, from /kisskb/src/include/linux/bitops.h:68, from /kisskb/src/include/linux/kernel.h:23, from /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:32: /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c: In function 'sun3_82586_timeout': /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:990:108: warning: array subscript 1 is above array bounds of 'volatile struct transmit_cmd_struct *[1]' [-Warray-bounds] printk("%s: command-stats: %04x %04x\n",dev->name,swab16(p->xmit_cmds[0]->cmd_status),swab16(p->xmit_cmds[1]->cmd_status));
