Subject[RFC PATCH v6 00/11] Control-flow Enforcement: Branch Tracking, PTRACE
Date
The previous version of CET Branch Tracking/PTRACE patches is at the following
link:

https://lkml.org/lkml/2018/10/11/662

Summary of changes from v5:

Remove the legacy code bitmap allocation from kernel. Now GLIBC
allocates the bitmap and passes it to the kernel.

Some small fixes.

H.J. Lu (3):
x86: Insert endbr32/endbr64 to vDSO
x86/vsyscall/32: Add ENDBR32 to vsyscall entry point
x86/vsyscall/64: Add ENDBR64 to vsyscall entry points

Yu-cheng Yu (8):
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
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/cet: Add PTRACE interface for CET
