Because # there could be a need for the stack to be executable, assembler sources # have to opt-in to this security feature via explicit creation of the # .note.GNU-stack feature (which compilers create by default) or command # line flag --noexecstack. Or we can simply tell the linker the # production of such sections is irrelevant and to link the stack as # --noexecstack. # # LLVM's LLD linker defaults to -z noexecstack, so this flag isn't # strictly necessary when linking with LLD, only BFD, but it doesn't hurt # to be explicit here for all linkers IMO. --no-warn-rwx-segments is # currently BFD specific and only available in the current latest release, # so it's wrapped in an ld-option check. # # While the kernel makes extensive usage of ELF sections, it doesn't use # permissions from ELF segments. # # Link: https://lore.kernel.org/linux-block/3af4127a-f453-4cf7-f133-a181cce06f73@kernel.dk/ # Link: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=ba951afb99912da01a6e8434126b8fac7aa75107 # Link: https://github.com/llvm/llvm-project/issues/57009 # Reported-and-tested-by: Jens Axboe <axboe@kernel.dk> # Suggested-by: Fangrui Song <maskray@google.com> # Signed-off-by: Nick Desaulniers <ndesaulniers@google.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 ffcf9c5700e49c0aee42dcba9a12ba21338e8136 # < make -s -j 32 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- allyesconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_KCOV=n # Added to kconfig # < make -s -j 32 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 32 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 32 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- Completed OK # rm -rf /kisskb/build/linus_s390-allyesconfig_s390x-gcc11 # Build took: 0:20:48.744390
