bool "Landlock support"
depends on SECURITY && !ARCH_EPHEMERAL_INODES
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 CONFIG_LSM to
enable Landlock at boot time.
