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/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 ffcf9c5700e49c0aee42dcba9a12ba21338e8136 # < make -s -j 8 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- randconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_BPF_PRELOAD=n # Added to kconfig # < make -s -j 8 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 8 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig .config:7247:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:7249:warning: override: reassigning to symbol GCC_PLUGINS # make -s -j 8 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- /kisskb/src/sound/soc/mediatek/mt8186/mt8186-mt6366-da7219-max98357.c:873:28: error: 'mt8186_mt6366_da7219_max98357_soc_card' defined but not used [-Werror=unused-variable] 873 \| static struct snd_soc_card mt8186_mt6366_da7219_max98357_soc_card = { \| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[5]: * [/kisskb/src/scripts/Makefile.build:249: sound/soc/mediatek/mt8186/mt8186-mt6366-da7219-max98357.o] Error 1 make[4]: * [/kisskb/src/scripts/Makefile.build:465: sound/soc/mediatek/mt8186] Error 2 make[3]: * [/kisskb/src/scripts/Makefile.build:465: sound/soc/mediatek] Error 2 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:465: sound/soc] Error 2 make[1]: * [/kisskb/src/Makefile:1855: sound] Error 2 make[1]: * Waiting for unfinished jobs.... make: * [Makefile:222: __sub-make] Error 2 Command 'make -s -j 8 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 # Build took: 0:14:21.761966
