Subject: [PATCH 1/3] linux: Enable Indirect Branch Tracking by default
Date: Sun, 09 Jul 2023 14:55:00 +0000 [thread overview]
Message-ID: <d753cd03-007f-d78c-848e-cc72459fded8@ipfire.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 1667 bytes --]
This became upstream default (see
https://www.phoronix.com/news/Linux-IBT-By-Default-Tip for IT news media
coverage), and given its security-relevance, we should adopt this
setting as well.
