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/aarch64-linux/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 ffcf9c5700e49c0aee42dcba9a12ba21338e8136 # < make -s -j 32 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- randconfig # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # < make -s -j 32 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- help # make -s -j 32 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- olddefconfig # make -s -j 32 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- /kisskb/src/drivers/infiniband/core/user_mad.c: In function 'ib_umad_write': /kisskb/src/drivers/infiniband/core/user_mad.c:564:50: error: array subscript 'struct ib_rmpp_mad[0]' is partly outside array bounds of 'unsigned char[140]' [-Werror=array-bounds] 564 \| hdr_len = ib_get_mad_data_offset(rmpp_mad->mad_hdr.mgmt_class); \| ^~ /kisskb/src/drivers/infiniband/core/user_mad.c:509:18: note: referencing an object of size 140 allocated by 'kzalloc.constprop' 509 \| packet = kzalloc(sizeof packet + IB_MGMT_RMPP_HDR, GFP_KERNEL); \| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/infiniband/core/user_mad.c:566:42: error: array subscript 'struct ib_rmpp_mad[0]' is partly outside array bounds of 'unsigned char[140]' [-Werror=array-bounds] 566 \| if (ib_is_mad_class_rmpp(rmpp_mad->mad_hdr.mgmt_class) \| ^~ /kisskb/src/drivers/infiniband/core/user_mad.c:509:18: note: referencing an object of size 140 allocated by 'kzalloc.constprop' 509 \| packet = kzalloc(sizeof packet + IB_MGMT_RMPP_HDR, GFP_KERNEL); \| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/infiniband/core/user_mad.c:618:25: error: array subscript 'struct ib_rmpp_mad[0]' is partly outside array bounds of 'unsigned char[140]' [-Werror=array-bounds] 618 \| rmpp_mad->mad_hdr.tid = tid; \| ^~ /kisskb/src/drivers/infiniband/core/user_mad.c:509:18: note: referencing an object of size 140 allocated by 'kzalloc.constprop' 509 \| packet = kzalloc(sizeof packet + IB_MGMT_RMPP_HDR, GFP_KERNEL); \| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/infiniband/core/user_mad.c:622:44: error: array subscript 'struct ib_rmpp_mad[0]' is partly outside array bounds of 'unsigned char[140]' [-Werror=array-bounds] 622 \| && ib_is_mad_class_rmpp(rmpp_mad->mad_hdr.mgmt_class) \| ^~ /kisskb/src/drivers/infiniband/core/user_mad.c:509:18: note: referencing an object of size 140 allocated by 'kzalloc.constprop' 509 \| packet = kzalloc(sizeof packet + IB_MGMT_RMPP_HDR, GFP_KERNEL); \| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[4]: [/kisskb/src/scripts/Makefile.build:249: drivers/infiniband/core/user_mad.o] Error 1 make[4]: * Waiting for unfinished jobs.... make[3]: * [/kisskb/src/scripts/Makefile.build:465: drivers/infiniband/core] Error 2 make[2]: * [/kisskb/src/scripts/Makefile.build:465: drivers/infiniband] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1855: drivers] Error 2 make: *** [Makefile:222: __sub-make] Error 2 Command 'make -s -j 32 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus-rand_arm64-randconfig_arm64-gcc11 # Build took: 0:09:29.086449
