22	depends on SECURITY_APPARMOR
23	select CRYPTO

25	default y

27	  This option selects whether introspection of loaded policy
28	  is available to userspace via the apparmor filesystem.

31       bool "Enable policy hash introspection by default"
32       depends on SECURITY_APPARMOR_HASH
33       default y
34       help
35         This option selects whether sha1 hashing of loaded policy
36	 is enabled by default. The generation of sha1 hashes for
37	 loaded policy provide system administrators a quick way
38	 to verify that policy in the kernel matches what is expected,
39	 however it can slow down policy load on some devices. In
40	 these cases policy hashing can be disabled by default and
41	 enabled only if needed.

43config SECURITY_APPARMOR_DEBUG
44	bool "Build AppArmor with debug code"
45	depends on SECURITY_APPARMOR
46	default n
47	help
48	  Build apparmor with debugging logic in apparmor. Not all
49	  debugging logic will necessarily be enabled. A submenu will
50	  provide fine grained control of the debug options that are
51	  available.

53config SECURITY_APPARMOR_DEBUG_ASSERTS
54	bool "Build AppArmor with debugging asserts"
55	depends on SECURITY_APPARMOR_DEBUG
56	default y
57	help
58	  Enable code assertions made with AA_BUG. These are primarily
59	  function entry preconditions but also exist at other key
60	  points. If the assert is triggered it will trigger a WARN
61	  message.

63config SECURITY_APPARMOR_DEBUG_MESSAGES
64	bool "Debug messages enabled by default"
65	depends on SECURITY_APPARMOR_DEBUG
66	default n
67	help
68	  Set the default value of the apparmor.debug kernel parameter.
69	  When enabled, various debug messages will be logged to
70	  the kernel message buffer.
