We recently simplified # some code that was thought unnecessary; however, since then KVM has # grown quite a few cond_resched()s and for that reason the simplified # code is prone to livelocks---one CPUs tries to empty a list of guest # page tables while the others keep adding to them. This adds back the # generation-based zapping of guest page tables, which was not # unnecessary after all. # # On top of this, there is a fix for a kernel memory leak and a couple # of s390 fixlets as well" # # * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: # KVM: x86/mmu: Reintroduce fast invalidate/zap for flushing memslot # KVM: x86: work around leak of uninitialized stack contents # KVM: nVMX: handle page fault in vmread # KVM: s390: Do not leak kernel stack data in the KVM_S390_INTERRUPT ioctl # KVM: s390: kvm_s390_vm_start_migration: check dirty_bitmap before using it as target for memset() # < /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 1609d7604b847a9820e63393d1a3b6cac7286d40 # < make -s -j 24 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 # yes \n | make -s -j 24 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 oldconfig yes: standard output: Broken pipe # make -s -j 24 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/signal.c: In function 'timer_real_alarm_handler': /kisskb/src/arch/um/os-Linux/signal.c:93:1: warning: the frame size of 2960 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/arch/um/os-Linux/signal.c: In function 'sig_handler_common': /kisskb/src/arch/um/os-Linux/signal.c:51:1: warning: the frame size of 2976 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/security/apparmor/policy_unpack.c: In function 'unpack_profile': /kisskb/src/security/apparmor/policy_unpack.c:523:9: warning: 'pos' may be used uninitialized in this function [-Wmaybe-uninitialized] str[pos] = ':'; ^ /kisskb/src/security/apparmor/policy_unpack.c:494:14: note: 'pos' was declared here int c, j, pos, size2 = unpack_strdup(e, &str, NULL); ^ /kisskb/src/mm/hmm.c: In function 'hmm_vma_walk_pud': /kisskb/src/mm/hmm.c:753:9: error: implicit declaration of function 'pud_pfn' [-Werror=implicit-function-declaration] pfn = pud_pfn(pud) + ((addr & ~PUD_MASK) >> PAGE_SHIFT); ^ cc1: some warnings being treated as errors make[2]: *** [/kisskb/src/scripts/Makefile.build:281: mm/hmm.o] Error 1 make[2]: *** Waiting for unfinished jobs.... make[1]: *** [/kisskb/src/Makefile:1083: mm] Error 2 make[1]: *** Waiting for unfinished jobs.... /kisskb/src/drivers/misc/lkdtm/bugs.c: In function 'lkdtm_UNSET_SMEP': /kisskb/src/drivers/misc/lkdtm/bugs.c:279:8: error: implicit declaration of function 'native_read_cr4' [-Werror=implicit-function-declaration] cr4 = native_read_cr4(); ^ /kisskb/src/drivers/misc/lkdtm/bugs.c:281:13: error: 'X86_CR4_SMEP' undeclared (first use in this function) if ((cr4 & X86_CR4_SMEP) != X86_CR4_SMEP) { ^ /kisskb/src/drivers/misc/lkdtm/bugs.c:281:13: note: each undeclared identifier is reported only once for each function it appears in /kisskb/src/drivers/misc/lkdtm/bugs.c:288:2: error: implicit declaration of function 'native_write_cr4' [-Werror=implicit-function-declaration] native_write_cr4(cr4); ^ cc1: some warnings being treated as errors make[4]: *** [/kisskb/src/scripts/Makefile.build:281: drivers/misc/lkdtm/bugs.o] Error 1 make[3]: *** [/kisskb/src/scripts/Makefile.build:497: drivers/misc/lkdtm] Error 2 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [/kisskb/src/scripts/Makefile.build:497: drivers/misc] Error 2 make[2]: *** Waiting for unfinished jobs.... make[1]: *** [/kisskb/src/Makefile:1083: drivers] Error 2 make: *** [Makefile:179: sub-make] Error 2 Command 'make -s -j 24 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 ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_um-allmodconfig_um-x86_64 # Build took: 0:06:46.317281
