However, it was overeager and also refused # to truncate arguments as well, which broke userspace, and it was # reverted. This attempts the protection again, but allows arguments to # remain truncated. In an effort to improve readability, helper functions # and comments have been added. # # Co-developed-by: Linus Torvalds # Signed-off-by: Kees Cook # Cc: Andrew Morton # Cc: Oleg Nesterov # Cc: Samuel Dionne-Riel # Cc: Richard Weinberger # Cc: Graham Christensen # Cc: Michal Hocko # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 b5372fe5dc84235dbe04998efdede3c4daa866a9 # < make -s -j 40 ARCH=mips O=/kisskb/build/linus_mips-allnoconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- allnoconfig # make -s -j 40 ARCH=mips O=/kisskb/build/linus_mips-allnoconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- FIT description: Linux 5.0.0-rc7+ Created: Tue Feb 19 19:42:21 2019 Image 0 (kernel@0) Description: Linux 5.0.0-rc7+ Created: Tue Feb 19 19:42:21 2019 Type: Kernel Image Compression: gzip compressed Data Size: 633625 Bytes = 618.77 KiB = 0.60 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x8021c2e0 Hash algo: sha1 Hash value: 4c3442b919e8d33dde38754d660ed1fe9f3f7adb Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Completed OK # rm -rf /kisskb/build/linus_mips-allnoconfig_mips-gcc8 # Build took: 0:00:10.984188
