Depending on the detection mode it # either warns and disables detection for the task or kills the task if # the mode is set to fatal" # # * tag 'x86-urgent-2020-04-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # KVM: VMX: Extend VMXs #AC interceptor to handle split lock #AC in guest # KVM: x86: Emulate split-lock access as a write in emulator # x86/split_lock: Provide handle_guest_split_lock() # < /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 4f8a3cc1183c442daee6cc65360e3385021131e4 # < make -s -j 48 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/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 # < make -s -j 48 ARCH=um O=/kisskb/build/linus_um-allyesconfig_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 48 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:4245:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:4247:warning: override: reassigning to symbol UML_NET_SLIP .config:4250:warning: override: reassigning to symbol UML_NET_MCAST .config:4252:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 48 ARCH=um O=/kisskb/build/linus_um-allyesconfig_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 '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/arch/um/os-Linux/signal.c: In function 'timer_real_alarm_handler': /kisskb/src/arch/um/os-Linux/signal.c:95:1: warning: the frame size of 2960 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/kernel/futex.c: In function 'futex_atomic_op_inuser': /kisskb/src/kernel/futex.c:1686:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval > cmparg; ^ /kisskb/src/security/apparmor/policy_unpack.c: In function 'unpack_profile': /kisskb/src/security/apparmor/policy_unpack.c:526:9: warning: 'pos' may be used uninitialized in this function [-Wmaybe-uninitialized] str[pos] = ':'; ^ /kisskb/src/security/apparmor/policy_unpack.c:497:14: note: 'pos' was declared here int c, j, pos, size2 = unpack_strdup(e, &str, NULL); ^ /kisskb/src/drivers/vdpa/vdpa_sim/vdpa_sim.c: In function 'vdpasim_create': /kisskb/src/drivers/vdpa/vdpa_sim/vdpa_sim.c:324:2: error: implicit declaration of function 'set_dma_ops' [-Werror=implicit-function-declaration] set_dma_ops(dev, &vdpasim_dma_ops); ^ cc1: some warnings being treated as errors make[4]: *** [/kisskb/src/scripts/Makefile.build:267: drivers/vdpa/vdpa_sim/vdpa_sim.o] Error 1 make[3]: *** [/kisskb/src/scripts/Makefile.build:488: drivers/vdpa/vdpa_sim] Error 2 make[2]: *** [/kisskb/src/scripts/Makefile.build:488: drivers/vdpa] Error 2 make[2]: *** Waiting for unfinished jobs.... /kisskb/src/lib/lz4/lz4hc_compress.c: In function 'LZ4HC_compress_generic': /kisskb/src/lib/lz4/lz4hc_compress.c:579:1: warning: the frame size of 2144 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ make[1]: *** [/kisskb/src/Makefile:1722: drivers] Error 2 make[1]: *** Waiting for unfinished jobs....
