Subject: [PATCH v8 0/6] Enable CET support for guest
Date: Thu, 20 May 2021 13:57:05 +0800	[thread overview]
Message-ID: <1621490231-4765-1-git-send-email-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 v8:
- Extended xsave_area_size() to accommodate compacted format size calculation.
- Added CPUID(0xD,1).EBX assigment per maintain's feedback.
- Changed XSS field check and added more comments to make things clearer.
- Other ajustment per maintainer's review feedback.
- Rebased to 6.0.0.
