From 41d58ef4f39924322c6517e1efc27d7f57be4dd0 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Peter=20M=C3=BCller?= Date: Mon, 26 Dec 2022 19:30:54 +0000 Subject: [PATCH] linux: Enable Landlock support MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit From the kernel's documentation: > Landlock is a sandboxing mechanism that enables processes to restrict > themselves (and their future children) by gradually enforcing > tailored access control policies. A Landlock security policy is a > set of access rights (e.g. open a file in read-only, make a > directory, etc.) tied to a file hierarchy. Such policy can be > configured and enforced by any processes for themselves using the > dedicated system calls: landlock_create_ruleset(), > landlock_add_rule(), and landlock_restrict_self(). There is no harm in enabling this security feature, so applications supporting Landlock can benefit from it. Rolled forward from https://patchwork.ipfire.org/project/ipfire/patch/d7ac0caf-5a7c-bcca-6293-16c773523942@ipfire.org/ to submit all kernel-related changes as a single patchset.
