Add Branch Tracking in the signal handling routines. Fix Branch Tracking (and Shadow Stack) for vsyscall (patch #12): This patch can be dropped if we expect CET blocking vsyscall. Include H.J. Lu's patch to discard .note.gnu.property in the kernel. H.J. Lu (4): x86/vdso: Insert endbr32/endbr64 to vDSO x86/vdso/32: Add ENDBR32 to __kernel_vsyscall entry point x86/vsyscall/64: Add ENDBR64 to vsyscall entry points x86: Discard .note.gnu.property sections Yu-cheng Yu (10): x86/cet/ibt: Add Kconfig option for user-mode Indirect Branch Tracking x86/cet/ibt: User-mode indirect branch tracking support x86/cet/ibt: Add IBT legacy code bitmap setup function x86/cet/ibt: Handle signals for IBT mm/mmap: Add IBT bitmap size to address space limit check x86/cet/ibt: ELF header parsing for IBT x86/cet/ibt: Add arch_prctl functions for IBT x86/cet/ibt: Add ENDBR to op-code-map x86/vsyscall/64: Fixup shadow stack and branch tracking for vsyscall x86/cet: Add PTRACE interface for CET arch/x86/Kconfig | 16 ++++ arch/x86/Makefile | 7 ++ arch/x86/entry/vdso/Makefile | 12 ++- arch/x86/entry/vdso/vdso-layout.lds.S | 1 + arch/x86/entry/vdso/vdso32/system_call.S | 3 + arch/x86/entry/vsyscall/vsyscall_64.c | 28 +++++++ arch/x86/entry/vsyscall/vsyscall_emu_64.S | 9 +++ arch/x86/include/asm/cet.h | 8 ++ arch/x86/include/asm/disabled-features.h | 8 +- arch/x86/include/asm/fpu/regset.h | 7 +- arch/x86/include/asm/mmu_context.h | 10 +++ arch/x86/include/uapi/asm/prctl.h | 2 + arch/x86/kernel/cet.c | 80 +++++++++++++++++++ arch/x86/kernel/cet_prctl.c | 21 +++++ arch/x86/kernel/cpu/common.c | 17 ++++ arch/x86/kernel/fpu/regset.c | 41 ++++++++++ arch/x86/kernel/process_64.c | 6 ++ arch/x86/kernel/ptrace.c | 16 ++++ arch/x86/kernel/vmlinux.lds.S | 11 ++- arch/x86/lib/x86-opcode-map.txt | 13 ++- include/uapi/linux/elf.h | 1 + mm/mmap.c | 19 ++++- .../arch/x86/include/asm/disabled-features.h | 8 +- tools/objtool/arch/x86/lib/x86-opcode-map.txt | 13 ++- 24 files changed, 345 insertions(+), 12 deletions(-) -- 2.17.1
