That avoids the Spectre-v1 speculation barriers. # # Right now only x86-64 takes advantage of this, and not all architectures # will be able to do it. It requires a guard region between the user and # kernel address spaces (so that you can't overflow from one to the # other), and an easy way to generate a guaranteed-to-fault address for # invalid user pointers. # # Also note that this currently assumes that there is no difference # between user read and write accesses. If extended to architectures like # powerpc, we'll also need to separate out the user read-vs-write cases. # # * address-masking: # x86: make the masked_user_access_begin() macro use its argument only once # x86: do the user address masking outside the user access area # x86: support user address masking instead of non-speculative conditional # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 de5cb0dcb74c294ec527eddfe5094acfdb21ff21 # make -s -j 24 ARCH=s390 O=/kisskb/build/linus_defconfig_s390x-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/s390-linux/bin/s390-linux- defconfig # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig # < make -s -j 24 ARCH=s390 O=/kisskb/build/linus_defconfig_s390x-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 24 ARCH=s390 O=/kisskb/build/linus_defconfig_s390x-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig .config:3999:warning: override: reassigning to symbol DEBUG_INFO_BTF # make -s -j 24 ARCH=s390 O=/kisskb/build/linus_defconfig_s390x-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/s390-linux/bin/s390-linux- Completed OK # rm -rf /kisskb/build/linus_defconfig_s390x-gcc13 # Build took: 0:10:37.120419
