Subject: [RFC PATCH v2 00/27] Control Flow Enforcement (CET)
Date: Tue, 10 Jul 2018 15:26:12 -0700	[thread overview]
Message-ID: <20180710222639.8241-1-yu-cheng.yu@intel.com> (raw)

The first version of CET patches were divided into four series.

Summary of changes in v2:

  Small fixes in the XSAVES patches.
  Improve: Documentation/x86/intel_cet.txt.
  Remove TLB flushing from ptep/pmdp_set_wrprotect for SHSTK.
  Use shadow stack restore token for signals; save SHSTK pointer after FPU.
  Rewrite ELF header parsing.
  Backward compatibility is now handled from GLIBC tunables.
  Add a new patch to can_follow_write_pte/pmd, for SHSTK.
  Remove blocking of mremap/madvice/munmap.
  Add Makefile checking CET support of assembler/compiler.
