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-6293-16... to submit all kernel-related changes as a single patchset.
