+config SECURITY_APPARMOR
+ bool "AppArmor support"
+ depends on SECURITY && NET
+ select AUDIT
+ select SECURITY_PATH
+ select SECURITYFS
+ select SECURITY_NETWORK
+ default n
+ help
+ This enables the AppArmor security module.
+ Required userspace tools (if they are not included in your
+ distribution) and further information may be found at
+ http://apparmor.wiki.kernel.org
+
+ If you are unsure how to answer this question, answer N.
+
+config SECURITY_APPARMOR_DEBUG
+ bool "Build AppArmor with debug code"
+ depends on SECURITY_APPARMOR
+ default n
+ help
+ Build apparmor with debugging logic in apparmor. Not all
+ debugging logic will necessarily be enabled. A submenu will
+ provide fine grained control of the debug options that are
+ available.
+
+config SECURITY_APPARMOR_DEBUG_ASSERTS
+ bool "Build AppArmor with debugging asserts"
+ depends on SECURITY_APPARMOR_DEBUG
+ default y
+ help
+ Enable code assertions made with AA_BUG. These are primarily
+ function entry preconditions but also exist at other key
+ points. If the assert is triggered it will trigger a WARN
+ message.
+
+config SECURITY_APPARMOR_DEBUG_MESSAGES
+ bool "Debug messages enabled by default"
+ depends on SECURITY_APPARMOR_DEBUG
+ default n
+ help
+ Set the default value of the apparmor.debug kernel parameter.
+ When enabled, various debug messages will be logged to
+ the kernel message buffer.
+
+config SECURITY_APPARMOR_INTROSPECT_POLICY
+ bool "Allow loaded policy to be introspected"
+ depends on SECURITY_APPARMOR
+ default y
+ help
+ This option selects whether introspection of loaded policy
+ is available to userspace via the apparmor filesystem. This
+ adds to kernel memory usage. It is required for introspection
+ of loaded policy, and check point and restore support. It
+ can be disabled for embedded systems where reducing memory and
+ cpu is paramount.
+
+config SECURITY_APPARMOR_HASH
+ bool "Enable introspection of sha1 hashes for loaded profiles"
+ depends on SECURITY_APPARMOR_INTROSPECT_POLICY
+ select CRYPTO
+ select CRYPTO_SHA1
+ default y
+ help
+ This option selects whether introspection of loaded policy
+ hashes is available to userspace via the apparmor
+ filesystem. This option provides a light weight means of
+ checking loaded policy. This option adds to policy load
+ time and can be disabled for small embedded systems.
+
+config SECURITY_APPARMOR_HASH_DEFAULT
+ bool "Enable policy hash introspection by default"
+ depends on SECURITY_APPARMOR_HASH
+ default y
+ help
+ This option selects whether sha1 hashing of loaded policy
+ is enabled by default. The generation of sha1 hashes for
+ loaded policy provide system administrators a quick way
+ to verify that policy in the kernel matches what is expected,
+ however it can slow down policy load on some devices. In
+ these cases policy hashing can be disabled by default and
+ enabled only if needed.
+
+config SECURITY_APPARMOR_EXPORT_BINARY
+ bool "Allow exporting the raw binary policy"
+ depends on SECURITY_APPARMOR_INTROSPECT_POLICY
+ select ZLIB_INFLATE
+ select ZLIB_DEFLATE
+ default y
+ help
+ This option allows reading back binary policy as it was loaded.
+ It increases the amount of kernel memory needed by policy and
+ also increases policy load time. This option is required for
+ checkpoint and restore support, and debugging of loaded policy.
+
+config SECURITY_APPARMOR_PARANOID_LOAD
+ bool "Perform full verification of loaded policy"
+ depends on SECURITY_APPARMOR
+ default y
+ help
+ This options allows controlling whether apparmor does a full
+ verification of loaded policy. This should not be disabled
+ except for embedded systems where the image is read only,
+ includes policy, and has some form of integrity check.
+ Disabling the check will speed up policy loads.
+
+config SECURITY_APPARMOR_KUNIT_TEST
+ tristate "Build KUnit tests for policy_unpack.c" if !KUNIT_ALL_TESTS
+ depends on KUNIT && SECURITY_APPARMOR
+ default KUNIT_ALL_TESTS
+ help
+ This builds the AppArmor KUnit tests.
+
+ KUnit tests run during boot and output the results to the debug log
+ in TAP format (https://testanything.org/). Only useful for kernel devs
+ running KUnit test harness and are not for inclusion into a
+ production build.
+
+ For more information on KUnit and unit tests in general please refer
+ to the KUnit documentation in Documentation/dev-tools/kunit/.
+
+ If unsure, say N.
