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/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 b5372fe5dc84235dbe04998efdede3c4daa866a9 # < make -s -j 40 ARCH=mips O=/kisskb/build/linus_mips-allnoconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- allnoconfig # make -s -j 40 ARCH=mips O=/kisskb/build/linus_mips-allnoconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- FIT description: Linux 5.0.0-rc7+ Created: Tue Feb 19 19:50:30 2019 Image 0 (kernel@0) Description: Linux 5.0.0-rc7+ Created: Tue Feb 19 19:50:30 2019 Type: Kernel Image Compression: gzip compressed Data Size: 632789 Bytes = 617.96 KiB = 0.60 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x8021b5a0 Hash algo: sha1 Hash value: 457eb426507ce7bb66a3e616521e4abd11ba887f Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Completed OK # rm -rf /kisskb/build/linus_mips-allnoconfig_mipsel # Build took: 0:00:11.479250
