# SPDX-License-Identifier: GPL-2.0-only config SECURITY_LANDLOCK bool "Landlock support" depends on SECURITY select SECURITY_NETWORK select SECURITY_PATH help 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. config SECURITY_LANDLOCK_KUNIT_TEST bool "KUnit tests for Landlock" if !KUNIT_ALL_TESTS depends on KUNIT=y depends on SECURITY_LANDLOCK default KUNIT_ALL_TESTS help Build KUnit tests for Landlock. See the KUnit documentation in Documentation/dev-tools/kunit Run all KUnit tests for Landlock with: ./tools/testing/kunit/kunit.py run --kunitconfig security/landlock If you are unsure how to answer this question, answer N.
