CET-IBT also limits speculation of the next # sequential instruction after the indirect CALL/JMP [1]. # # CET-IBT is fundamentally incompatible with retpolines, but provides, # as described above, speculation limits itself" # # [1] https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-guidance/technical-documentation/branch-history-injection.html # # * tag 'x86_core_for_5.18_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (53 commits) # kvm/emulate: Fix SETcc emulation for ENDBR # x86/Kconfig: Only allow CONFIG_X86_KERNEL_IBT with ld.lld >= 14.0.0 # x86/Kconfig: Only enable CONFIG_CC_HAS_IBT for clang >= 14.0.0 # kbuild: Fixup the IBT kbuild changes # x86/Kconfig: Do not allow CONFIG_X86_X32_ABI=y with llvm-objcopy # x86: Remove toolchain check for X32 ABI capability # x86/alternative: Use .ibt_endbr_seal to seal indirect calls # objtool: Find unused ENDBR instructions # objtool: Validate IBT assumptions # objtool: Add IBT/ENDBR decoding # objtool: Read the NOENDBR annotation # x86: Annotate idtentry_df() # x86,objtool: Move the ASM_REACHABLE annotation to objtool.h # x86: Annotate call_on_stack() # objtool: Rework ASM_REACHABLE # x86: Mark __invalid_creds() __noreturn # exit: Mark do_group_exit() __noreturn # x86: Mark stop_this_cpu() __noreturn # objtool: Ignore extra-symbol code # objtool: Rename --duplicate to --lto # ... # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 7001052160d172f6de06adeffde24dde9935ece8 # < make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- randconfig # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # < make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- help # make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- olddefconfig .config:5605:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD # make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- In file included from /kisskb/src/include/linux/string.h:253, from /kisskb/src/include/linux/bitmap.h:11, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/include/linux/smp.h:13, from /kisskb/src/arch/arm64/include/asm/arch_timer.h:18, from /kisskb/src/arch/arm64/include/asm/timex.h:8, from /kisskb/src/include/linux/timex.h:65, from /kisskb/src/include/linux/time32.h:13, from /kisskb/src/include/linux/time.h:60, from /kisskb/src/include/linux/stat.h:19, from /kisskb/src/include/linux/fcntl.h:5, from /kisskb/src/net/ipv4/tcp_ipv4.c:52: In function 'fortify_memcpy_chk', inlined from 'tcp_md5_do_add' at /kisskb/src/net/ipv4/tcp_ipv4.c:1210:2: /kisskb/src/include/linux/fortify-string.h:328:4: warning: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? __write_overflow_field(p_size_field, size); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 # Build took: 0:05:38.782449
