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-11.1.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 7001052160d172f6de06adeffde24dde9935ece8 # < make -s -j 32 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- sun3_defconfig # < make -s -j 32 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 32 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 32 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- In file included from /kisskb/src/include/linux/string.h:20, from /kisskb/src/include/linux/bitmap.h:11, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/include/linux/mm_types_task.h:14, from /kisskb/src/include/linux/mm_types.h:5, from /kisskb/src/include/linux/buildid.h:5, from /kisskb/src/include/linux/module.h:14, from /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:32: In function 'check586', inlined from 'sun3_82586_probe1' at /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:365:6, inlined from 'sun3_82586_probe' at /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:311:8: /kisskb/src/arch/m68k/include/asm/string.h:68:25: warning: '__builtin_memset' offset [0, 11] is out of the bounds [0, 0] [-Warray-bounds] 68 | #define memset(d, c, n) __builtin_memset(d, c, n) | ^~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:218:9: note: in expansion of macro 'memset' 218 | memset((char *)p->scp,0, sizeof(struct scp_struct));
