This patch uses mftb() instead of get_random_int() for better # performance. # # In order to avoid unconditional stack canaries on syscall entry (due to # the use of alloca()), also disable stack protector to avoid triggering # needless checks and slowing down the entry path. As there is no general # way to control stack protector coverage with a function attribute, this # must be disabled at the compilation unit level. # # Signed-off-by: Xiu Jianfeng <xiujianfeng@huawei.com> # Reviewed-by: Kees Cook <keescook@chromium.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20220701082435.126596-3-xiujianfeng@huawei.com # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 f4a0318f278d98d9492916722e85f258c2221f88 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64_defconfig # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-next_ppc64_defconfig_powerpc-gcc11 # Build took: 0:05:32.282333
