Make KVM_MEM_GUEST_MEMFD mutually exclusive with KVM_MEM_READONLY # to avoid creating an inconsistent ABI (KVM_MEM_GUEST_MEMFD is not # writable from userspace, so there would be no way to write to a # read-only guest_memfd). # # - Update documentation for KVM_SW_PROTECTED_VM to make it abundantly # clear that such VMs are purely for development and testing. # # - Limit KVM_SW_PROTECTED_VM guests to the TDP MMU, as the long term # plan is to support confidential VMs with deterministic private # memory (SNP and TDX) only in the TDP MMU. # # - Fix a bug in a GUEST_MEMFD dirty logging test that caused false # passes. # # x86 fixes: # # - Fix missing marking of a guest page as dirty when emulating an # atomic access. # # - Check for mmu_notifier invalidation events before faulting in the # pfn, and before acquiring mmu_lock, to avoid unnecessary work and # lock contention with preemptible kernels (including # CONFIG_PREEMPT_DYNAMIC in non-preemptible mode). # # - Disable AMD DebugSwap by default, it breaks VMSA signing and will # be re-enabled with a better VM creation API in 6.10. # # - Do the cache flush of converted pages in svm_register_enc_region() # before dropping kvm->lock, to avoid a race with unregistering of # the same region and the consequent use-after-free issue" # # * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: # SEV: disable SEV-ES DebugSwap by default # KVM: x86/mmu: Retry fault before acquiring mmu_lock if mapping is changing # KVM: SVM: Flush pages under kvm->lock to fix UAF in svm_register_enc_region() # KVM: selftests: Add a testcase to verify GUEST_MEMFD and READONLY are exclusive # KVM: selftests: Create GUEST_MEMFD for relevant invalid flags testcases # KVM: x86/mmu: Restrict KVM_SW_PROTECTED_VM to the TDP MMU # KVM: x86: Update KVM_SW_PROTECTED_VM docs to make it clear they're a WIP # KVM: Make KVM_MEM_GUEST_MEMFD mutually exclusive with KVM_MEM_READONLY # KVM: x86: Mark target gfn of emulated atomic instruction as dirty # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 137e0ec05aeb657472d2f84dbb3081016160334b # make -s -j 40 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 allyesconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig CONFIG_BPF_PRELOAD=n # Added to kconfig CONFIG_SPI_STM32_QSPI=n # < make -s -j 40 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 40 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:14391:warning: override: reassigning to symbol GCC_PLUGIN_LATENT_ENTROPY .config:14395:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:14397:warning: override: reassigning to symbol UML_NET_SLIP .config:14402:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 40 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/x86/um/user-offsets.c:17:6: warning: no previous prototype for ‘foo’ [-Wmissing-prototypes] 17 | void foo(void) | ^~~ In file included from /kisskb/src/arch/um/kernel/asm-offsets.c:1: /kisskb/src/arch/x86/um/shared/sysdep/kernel-offsets.h:9:6: error: no previous prototype for ‘foo’ [-Werror=missing-prototypes] 9 | void foo(void) | ^~~ cc1: all warnings being treated as errors make[3]: *** [/kisskb/src/scripts/Makefile.build:116: arch/um/kernel/asm-offsets.s] Error 1 make[2]: *** [/kisskb/src/Makefile:1199: prepare0] Error 2 make[1]: *** [/kisskb/src/Makefile:240: __sub-make] Error 2 make: *** [Makefile:240: __sub-make] Error 2 Command 'make -s -j 40 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 ' returned non-zero exit status 2. # rm -rf /kisskb/build/linus_allyesconfig_um-x86_64-gcc12 # Build took: 0:00:17.555849
