It seemed to get # dropped amid the discussion of other related changes, but this # part seems obviously correct on its own, so I've picked it up and # sent it, for expediency. # # Fixes: 64d2ab32efe3 ("vfs: fix put_compat_statfs64() does not handle errors") # Signed-off-by: Eric Sandeen <sandeen@redhat.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /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 cc3a7bfe62b947b423fcb2cfe89fcba92bf48fa3 # < make -s -j 8 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 # yes \n \| make -s -j 8 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 oldconfig yes: standard output: Broken pipe # make -s -j 8 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/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/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=] } ^ /kisskb/src/drivers/misc/lkdtm/bugs.c: In function 'lkdtm_UNSET_SMEP': /kisskb/src/drivers/misc/lkdtm/bugs.c:284:8: error: implicit declaration of function 'native_read_cr4' [-Werror=implicit-function-declaration] cr4 = native_read_cr4(); ^ /kisskb/src/drivers/misc/lkdtm/bugs.c:286:13: 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:286:13: note: each undeclared identifier is reported only once for each function it appears in /kisskb/src/drivers/misc/lkdtm/bugs.c:293:2: 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:266: drivers/misc/lkdtm/bugs.o] Error 1 make[4]: * Waiting for unfinished jobs.... make[3]: * [/kisskb/src/scripts/Makefile.build:509: drivers/misc/lkdtm] Error 2 make[2]: * [/kisskb/src/scripts/Makefile.build:509: drivers/misc] Error 2 make[1]: * [/kisskb/src/Makefile:1670: drivers] Error 2 make[1]: * Waiting for unfinished jobs.... make: * [Makefile:179: sub-make] Error 2 Command 'make -s -j 8 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 ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_um-allyesconfig_um-x86_64 # Build took: 0:10:55.650584
