Subject: [PATCH 0/7] Control Flow Enforcement - Part (4)
Date: Thu,  7 Jun 2018 07:38:48 -0700	[thread overview]
Message-ID: <20180607143855.3681-1-yu-cheng.yu@intel.com> (raw)

This series introduces CET - indirect branch tracking

The major task of indirect branch tracking is for the compiler to
insert the ENDBR instructions at all valid branch targets.

The kernel provides:
	CPUID enumeration and feature setup;
	Legacy bitmap allocation;
	Some basic supporting routines.

In this patch, there are also a CET command-line utility and
PTRACE support.

H.J. Lu (2):
  x86: Insert endbr32/endbr64 to vDSO
  tools: Add cetcmd

Yu-cheng Yu (5):
  x86/cet: Add Kconfig option for user-mode Indirect Branch Tracking
  x86/cet: User-mode indirect branch tracking support
  mm/mmap: Add IBT bitmap size to address space limit check
  x86/cet: add arcp_prctl functions for indirect branch tracking
  x86/cet: Add PTRACE interface for CET
