If panic_on_warn was set, # __ubsan_handle_divrem_overflow would panic. # # The problem is is that panic_on_warn is run time configurable. If it's # disabled, then we cannot guarantee that we will be able to recover # safely. Disable this config for clang until we can come up with a # solution in LLVM. # # Link: https://github.com/ClangBuiltLinux/linux/issues/1657 # Link: https://github.com/llvm/llvm-project/issues/56289 # Link: https://lore.kernel.org/lkml/CAHk-=wj1qhf7y3VNACEexyp5EbkNpdcu_542k-xZpzmYLOjiCg@mail.gmail.com/ # Reported-by: Sudip Mukherjee <sudipm.mukherjee@gmail.com> # Suggested-by: Linus Torvalds <torvalds@linux-foundation.org> # Signed-off-by: Nick Desaulniers <ndesaulniers@google.com> # Acked-by: Nathan Chancellor <nathan@kernel.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 e5d523f1ae8f2cef01f8e071aeee432654166708 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=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_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 32 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:6333:warning: override: reassigning to symbol MODULE_SIG .config:6335:warning: override: reassigning to symbol PPC64 .config:6337:warning: override: reassigning to symbol SECTION_MISMATCH_WARN_ONLY .config:6338:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:6340:warning: override: reassigning to symbol GCC_PLUGINS .config:6342:warning: override: reassigning to symbol TRIM_UNUSED_KSYMS # make -s -j 32 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/mm/damon/vaddr.c:701: /kisskb/src/mm/damon/vaddr-test.h: In function 'damon_test_three_regions_in_vmas': /kisskb/src/mm/damon/vaddr-test.h:96:1: error: the frame size of 1296 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] 96 \| } \| ^ cc1: all warnings being treated as errors make[3]: * [/kisskb/src/scripts/Makefile.build:249: mm/damon/vaddr.o] Error 1 make[2]: * [/kisskb/src/scripts/Makefile.build:466: mm/damon] Error 2 make[1]: * [/kisskb/src/Makefile:1843: mm] Error 2 make[1]: * Waiting for unfinished jobs.... /kisskb/src/fs/jffs2/xattr.c: In function 'jffs2_build_xattr_subsystem': /kisskb/src/fs/jffs2/xattr.c:887:1: error: the frame size of 1072 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] 887 \| } \| ^ cc1: all warnings being treated as errors make[3]: * [/kisskb/src/scripts/Makefile.build:249: fs/jffs2/xattr.o] Error 1 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:466: fs/jffs2] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1843: fs] Error 2 make: *** [Makefile:219: __sub-make] Error 2 Command 'make -s -j 32 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 # Build took: 0:00:47.471745
