Subject: [PATCH v17 0/7] Control-flow Enforcement: Indirect Branch Tracking
Date: Tue, 29 Dec 2020 13:33:43 -0800 [thread overview]
Message-ID: <20201229213350.17010-1-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 v17:
- Rebase to v5.11-rc1.
