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-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 de5cb0dcb74c294ec527eddfe5094acfdb21ff21 # make -s -j 40 ARCH=sparc O=/kisskb/build/linus_sparc32_defconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- sparc32_defconfig # < make -s -j 40 ARCH=sparc O=/kisskb/build/linus_sparc32_defconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- help # make -s -j 40 ARCH=sparc O=/kisskb/build/linus_sparc32_defconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- olddefconfig # make -s -j 40 ARCH=sparc O=/kisskb/build/linus_sparc32_defconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] cc1: warning: unrecognized command line option '-Wno-shift-negative-value' cc1: warning: unrecognized command line option '-Wno-stringop-overflow' /kisskb/src/kernel/fork.c: In function '__do_sys_clone3': /kisskb/src/kernel/fork.c:3078:2: warning: #warning clone3() entry point is missing, please fix [-Wcpp] #warning clone3() entry point is missing, please fix ^ /kisskb/src/kernel/fork.c: At top level: cc1: warning: unrecognized command line option '-Wno-shift-negative-value' cc1: warning: unrecognized command line option '-Wno-stringop-overflow' Completed OK # rm -rf /kisskb/build/linus_sparc32_defconfig_sparc64-gcc5 # Build took: 0:00:26.128418
