Subject: [PATCH v23 0/9] Control-flow Enforcement: Indirect Branch Tracking
Date: Tue, 16 Mar 2021 08:13:10 -0700 [thread overview]
Message-ID: <20210316151320.6123-1-yu-cheng.yu@intel.com> (raw)
Control-flow Enforcement (CET) is a new Intel processor feature that blocks
return/jump-oriented programming attacks. Details are in "Intel 64 and
IA-32 Architectures Software Developer's Manual" [1].
This is the second part of CET and enables Indirect Branch Tracking (IBT).
It is built on top of the shadow stack series.
Changes in v23:
- Add patch #6: introduce a macro for ENDBR instructions.
- Patch #7: replace endbr32 with ENDBR macro.
- Patch #9: revise, add/replace endbr64 with ENDBR macro.
- Rebase to Linus tree v5.12-rc3.
