This feature has # happily lived in Android kernels for almost 3 years[1], so I'm excited # to have it ready for upstream. # # The wide diffstat is mainly due to the treewide fixing of mismatched # list_sort prototypes. Other things in core kernel are to address # various CFI corner cases. The largest code portion is the CFI runtime # implementation itself (which will be shared by all architectures # implementing support for CFI). The arm64 pieces are Acked by arm64 # maintainers rather than coming through the arm64 tree since carrying # this tree over there was going to be awkward. # # CFI support for x86 is still under development, but is pretty close. # There are a handful of corner cases on x86 that need some improvements # to Clang and objtool, but otherwise works well. # # Summary: # # - Clean up list_sort prototypes (Sami Tolvanen) # # - Introduce CONFIG_CFI_CLANG for arm64 (Sami Tolvanen)" # # * tag 'cfi-v5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: # arm64: allow CONFIG_CFI_CLANG to be selected # KVM: arm64: Disable CFI for nVHE # arm64: ftrace: use function_nocfi for ftrace_call # arm64: add __nocfi to __apply_alternatives # arm64: add __nocfi to functions that jump to a physical address # arm64: use function_nocfi with __pa_symbol # arm64: implement function_nocfi # psci: use function_nocfi for cpu_resume # lkdtm: use function_nocfi # treewide: Change list_sort to use const pointers # bpf: disable CFI in dispatcher functions # kallsyms: strip ThinLTO hashes from static functions # kthread: use WARN_ON_FUNCTION_MISMATCH # workqueue: use WARN_ON_FUNCTION_MISMATCH # module: ensure __cfi_check alignment # mm: add generic function_nocfi macro # cfi: add __cficanonical # add support for Clang CFI # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 57fa2369ab17d67e6232f85b868652fbf4407206 # < make -s -j 48 ARCH=x86_64 O=/kisskb/build/linus_x86_64-allnoconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allnoconfig # < make -s -j 48 ARCH=x86_64 O=/kisskb/build/linus_x86_64-allnoconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 48 ARCH=x86_64 O=/kisskb/build/linus_x86_64-allnoconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 48 ARCH=x86_64 O=/kisskb/build/linus_x86_64-allnoconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- /kisskb/src/kernel/static_call.c: In function '__static_call_update': /kisskb/src/kernel/static_call.c:153:18: warning: unused variable 'mod' [-Wunused-variable] struct module *mod = site_mod->mod; ^~~ Completed OK # rm -rf /kisskb/build/linus_x86_64-allnoconfig_x86_64-gcc8 # Build took: 0:00:22.632369
