In # hindsight, we should have spotted this in review when the PAN code was # merged back in v4.3, but hindsight is 20/20 and I'm trying not to beat # myself up too much about it despite being fairly miserable. # # Anyway, the fix is "obvious" but the actual failure is more more # subtle, and is described in the commit message. I've included a fairly # mechanical follow-up patch here as well, which moves this checking out # into the C wrappers which is what we do for {get,put}_user() already # and allows us to remove these bloody assembly macros entirely. The # patches have passed kernelci [1] [2] [3] and CKI [4] tests over night, # as well as some targetted testing [5] for this particular issue. # # The first patch is tagged for stable and should be applied to 4.14, # 4.19 and 5.3. I have separate backports for 4.4 and 4.9, which I'll # send out once this has landed in your tree (although the original # patch applies cleanly, it won't build for those two trees). # # Thanks to Pavel Tatashin for reporting this and Mark Rutland for # helping to diagnose the issue and review/test the solution" # # * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: # arm64: uaccess: Remove uaccess__not_uao asm macros # arm64: uaccess: Ensure PAN is re-enabled after unhandled uaccess fault # < /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 81429eb8d9ca40b0c65bb739d29fa856c5d5e958 # < make -s -j 10 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 10 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 10 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 '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[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[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1652: drivers] Error 2 make[1]: * Waiting for unfinished jobs.... make: *** [Makefile:179: sub-make] Error 2 Command 'make -s -j 10 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: 0:10:19.798519
