Since that's an assembly stub the # compiler would not generate the proper kCFI indirect call magic and it # would not get patched. # # Brian came up with the most comprehensive fix -- convert the thing to # C with only a very thin asm wrapper. This ensures the kernel thread # boostrap is a proper kCFI call. # # While discussing all this, Kees noted that kCFI hashes could/should be # poisoned to seal all functions whose address is never taken, further # limiting the valid kCFI targets -- much like we already do for IBT. # # So what was a 'simple' observation and fix cascaded into a bunch of # inter-related CFI infrastructure fixes" # # * tag 'x86_urgent_for_6.5_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/cfi: Only define poison_cfi() if CONFIG_X86_KERNEL_IBT=y # x86/fineibt: Poison ENDBR at +0 # x86: Rewrite ret_from_fork() in C # x86/32: Remove schedule_tail_wrapper() # x86/cfi: Extend ENDBR sealing to kCFI # x86/alternative: Rename apply_ibt_endbr() # x86/cfi: Extend {JMP,CAKK}_NOSPEC comment # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 b6e6cc1f78c772e952495b7416c9ac9029f9390c # make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r6el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- 64r6el_defconfig Using /kisskb/src/arch/mips/configs/generic_defconfig as base Merging /kisskb/src/arch/mips/configs/generic/64r6.config Merging /kisskb/src/arch/mips/configs/generic/el.config Merging /kisskb/src/arch/mips/configs/generic/board-boston.config Merging /kisskb/src/arch/mips/configs/generic/board-marduk.config Merging /kisskb/src/arch/mips/configs/generic/board-ranchu.config Merging /kisskb/src/arch/mips/configs/generic/board-virt.config # < make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r6el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r6el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r6el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- Completed OK # rm -rf /kisskb/build/linus_64r6el_defconfig_mips-gcc12 # Build took: 0:02:18.287807
