CONFIG_SECURITY_LANDLOCK: Landlock support

General informations

The Linux kernel configuration item CONFIG_SECURITY_LANDLOCK:

Help text

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().

See Documentation/userspace-api/landlock.rst for further information.

If you are unsure how to answer this question, answer N. Otherwise, you should also prepend "landlock," to the content of LSM to enable Landlock at boot time.
