Subject: [PATCH v7 0/6] Enable CET support for guest
Date: Fri, 26 Feb 2021 10:20:52 +0800	[thread overview]
Message-ID: <20210226022058.24562-1-weijiang.yang@intel.com> (raw)

Control-flow Enforcement Technology (CET) provides protection against
Return/Jump-Oriented Programming (ROP/JOP). It includes two features:
Shadow Stack(SHSTK) and Indirect Branch Tracking(IBT).
This patch series is to enable CET related CPUID report, XSAVES/XRSTORS
support and MSR access etc. for guest.

Change in v7:
- Reverted part of XSAVE feature-word naming change per review feedback.
- Fixed an issue blocking SHSTK and IBT used as two independent features
  if OS just enables either of them.
- Other minor changes during testing and review.
- Rebased to 5.2.0 base.
