While nobody should be enabling it in the # kernel (the only public users of the feature are the selftests), # the bug effectively allows userspace to read arbitrary memory. # # - Correctness fixes for nested hypervisors that do not intercept INIT # or SHUTDOWN on AMD; the subsequent CPU reset can cause a # use-after-free when it disables virtualization extensions. While # downgrading the panic to a WARN is quite easy, the full fix is a # bit more laborious; there are also tests. This is the bulk of the # pull request. # # - Fix race condition due to incorrect mmu_lock use around # make_mmu_pages_available(). # # Generic: # # - Obey changes to the kvm.halt_poll_ns module parameter in VMs not # using KVM_CAP_HALT_POLL, restoring behavior from before the # introduction of the capability" # # * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: # KVM: Update gfn_to_pfn_cache khva when it moves within the same page # KVM: x86/xen: Only do in-kernel acceleration of hypercalls for guest CPL0 # KVM: x86/xen: Validate port number in SCHEDOP_poll # KVM: x86/mmu: Fix race condition in direct_page_fault # KVM: x86: remove exit_int_info warning in svm_handle_exit # KVM: selftests: add svm part to triple_fault_test # KVM: x86: allow L1 to not intercept triple fault # kvm: selftests: add svm nested shutdown test # KVM: selftests: move idt_entry to header # KVM: x86: forcibly leave nested mode on vCPU reset # KVM: x86: add kvm_leave_nested # KVM: x86: nSVM: harden svm_free_nested against freeing vmcb02 while still in use # KVM: x86: nSVM: leave nested mode on vCPU free # KVM: Obey kvm.halt_poll_ns in VMs not using KVM_CAP_HALT_POLL # KVM: Avoid re-reading kvm->max_halt_poll_ns during halt-polling # KVM: Cap vcpu->halt_poll_ns before halting rather than after # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 bf82d38c91f857083f2d1b9770fa3df55db2ca3b # < make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 allmodconfig # 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 # < make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:12564:warning: override: reassigning to symbol GCC_PLUGIN_SANCOV .config:12569:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:12571:warning: override: reassigning to symbol UML_NET_SLIP .config:12574:warning: override: reassigning to symbol UML_NET_MCAST .config:12576:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/um/os-Linux/util.c:17:24: fatal error: sys/random.h: No such file or directory compilation terminated. make[3]: *** [/kisskb/src/scripts/Makefile.build:250: arch/um/os-Linux/util.o] Error 1 make[2]: *** [/kisskb/src/scripts/Makefile.build:500: arch/um/os-Linux] Error 2 make[2]: *** Waiting for unfinished jobs....
