However, some custom build rules # (e.g. nVHE or early PIE on arm64) use objcopy to add a prefix to all the # symbols in their object files, making mksysmap's ignore filter miss # those KCFI symbols. # # Therefore, explicitly list those twice-prefixed KCFI symbols as ignored. # # Alternatively, this could also be achieved in a less verbose way by # ignoring any symbol containing the string "__kcfi_typeid_". However, # listing the combined prefixes explicitly saves us from running the small # risk of ignoring symbols that should be kept. # # Signed-off-by: Pierre-Clément Tosi <ptosi@google.com> # Reviewed-by: Sami Tolvanen <samitolvanen@google.com> # Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/aarch64-linux/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/aarch64-linux/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 71025b8565a383223ea2d94325db37cdabbcc453 # make -s -j 160 ARCH=arm64 O=/kisskb/build/kbuild_defconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/aarch64-linux/bin/aarch64-linux- defconfig # < make -s -j 160 ARCH=arm64 O=/kisskb/build/kbuild_defconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/aarch64-linux/bin/aarch64-linux- help # make -s -j 160 ARCH=arm64 O=/kisskb/build/kbuild_defconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/aarch64-linux/bin/aarch64-linux- olddefconfig # make -s -j 160 ARCH=arm64 O=/kisskb/build/kbuild_defconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/aarch64-linux/bin/aarch64-linux- Completed OK # rm -rf /kisskb/build/kbuild_defconfig_arm64-gcc11 # Build took: 0:07:00.427392
