JIRA: https://issues.redhat.com/browse/RHEL-25415 Conflicts: The MAINTAINERS entry doesn't exist in RHEL9. commit 215199e3d9f3dc01a6d10b8229891e6f7f1085e7 Author: Kees Cook <keescook@chromium.org> Date: Thu Aug 24 21:25:55 2023 -0700 hardening: Provide Kconfig fragments for basic options Inspired by Salvatore Mesoraca's earlier[1] efforts to provide some in-tree guidance for kernel hardening Kconfig options, add a new fragment named "hardening-basic.config" (along with some arch-specific fragments) that enable a basic set of kernel hardening options that have the least (or no) performance impact and remove a reasonable set of legacy APIs. Using this fragment is as simple as running "make hardening.config". More extreme fragments can be added[2] in the future to cover all the recognized hardening options, and more per-architecture files can be added too. For now, document the fragments directly via comments. Perhaps .rst documentation can be generated from them in the future (rather than the other way around).
