A Landlock security policy is a 11 set of access rights (e.g. open a file in read-only, make a 12 directory, etc.) tied to a file hierarchy. Such policy can be 13 configured and enforced by any processes for themselves using the 14 dedicated system calls: landlock_create_ruleset(), 15 landlock_add_rule(), and landlock_restrict_self(). 16 17 See Documentation/userspace-api/landlock.rst for further information. 18 19 If you are unsure how to answer this question, answer N. Otherwise, 20 you should also prepend "landlock," to the content of CONFIG_LSM to 21 enable Landlock at boot time. 22
