Subject: [PATCH v7 00/14] Control-flow Enforcement: Branch Tracking, PTRACE
The previous version of CET Branch Tracking/PTRACE patches is here:
https://lkml.org/lkml/2018/11/20/203
Summary of changes from v6:
Rebase to v5.2-rc3.
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
