This has the desirable effect of ensuring # that all 'unsafe' accesses have been range-checked, without having to # pick through all of the callsites to verify whether the appropriate # checking has been made. # # However, the consolidated range check does not inhibit speculation, so # it is still up to the caller to ensure that they are not susceptible to # any speculative side-channel attacks for user addresses that ultimately # fail the access_ok() check. # # This is an oversight, so use __uaccess_begin_nospec() to ensure that # speculation is inhibited until the access_ok() check has passed. # # Reported-by: Julien Thierry <julien.thierry@arm.com> # Signed-off-by: Will Deacon <will.deacon@arm.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 6e693b3ffecb0b478c7050b44a4842854154f715 # < make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- randconfig KCONFIG_SEED=0xD323288C WARNING: unmet direct dependencies detected for ARM64_ERRATUM_845719 Depends on [n]: COMPAT [=n] Selected by [y]: - ARCH_MXC [=y] WARNING: unmet direct dependencies detected for TI_SOC_THERMAL Depends on [n]: THERMAL [=y] && (ARCH_HAS_BANDGAP \|\| COMPILE_TEST [=n]) && HAS_IOMEM [=y] Selected by [m]: - MMC_SDHCI_OMAP [=m] && MMC [=y] && MMC_SDHCI_PLTFM [=m] && OF [=y] WARNING: unmet direct dependencies detected for TI_SOC_THERMAL Depends on [n]: THERMAL [=y] && (ARCH_HAS_BANDGAP \|\| COMPILE_TEST [=n]) && HAS_IOMEM [=y] Selected by [m]: - MMC_SDHCI_OMAP [=m] && MMC [=y] && MMC_SDHCI_PLTFM [=m] && OF [=y] WARNING: unmet direct dependencies detected for ARM64_ERRATUM_845719 Depends on [n]: COMPAT [=n] Selected by [y]: - ARCH_MXC [=y] # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # yes \n \| make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:40: LSE atomics not supported by binutils WARNING: unmet direct dependencies detected for TI_SOC_THERMAL Depends on [n]: THERMAL [=y] && (ARCH_HAS_BANDGAP \|\| COMPILE_TEST [=n]) && HAS_IOMEM [=y] Selected by [m]: - MMC_SDHCI_OMAP [=m] && MMC [=y] && MMC_SDHCI_PLTFM [=m] && OF [=y] WARNING: unmet direct dependencies detected for ARM64_ERRATUM_845719 Depends on [n]: COMPAT [=n] Selected by [y]: - ARCH_MXC [=y] WARNING: unmet direct dependencies detected for ARM64_ERRATUM_845719 Depends on [n]: COMPAT [=n] Selected by [y]: - ARCH_MXC [=y] WARNING: unmet direct dependencies detected for TI_SOC_THERMAL Depends on [n]: THERMAL [=y] && (ARCH_HAS_BANDGAP \|\| COMPILE_TEST [=n]) && HAS_IOMEM [=y] Selected by [m]: - MMC_SDHCI_OMAP [=m] && MMC [=y] && MMC_SDHCI_PLTFM [=m] && OF [=y] WARNING: unmet direct dependencies detected for TI_SOC_THERMAL Depends on [n]: THERMAL [=y] && (ARCH_HAS_BANDGAP \|\| COMPILE_TEST [=n]) && HAS_IOMEM [=y] Selected by [m]: - MMC_SDHCI_OMAP [=m] && MMC [=y] && MMC_SDHCI_PLTFM [=m] && OF [=y] WARNING: unmet direct dependencies detected for ARM64_ERRATUM_845719 Depends on [n]: COMPAT [=n] Selected by [y]: - ARCH_MXC [=y] arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:40: LSE atomics not supported by binutils Completed OK # rm -rf /kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 # Build took: 0:03:26.093915
