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-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 71025b8565a383223ea2d94325db37cdabbcc453 # make -s -j 160 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- x86_64_defconfig # < make -s -j 160 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 160 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 160 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- Completed OK # rm -rf /kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 # Build took: 0:03:01.192142
