+config SECURITY_APPARMOR
+	bool "AppArmor support"
+	depends on SECURITY && SECURITY_NETWORK && NET && INET
+	select AUDIT
+	select SECURITY_PATH
+	select SECURITYFS
+	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://forge.novell.com/modules/xfmod/project/?apparmor>
+
+	  If you are unsure how to answer this question, answer N.

+config SECURITY_APPARMOR_NETWORK
+       bool "AppArmor network support"
+       depends on SECURITY_APPARMOR
+       default n
+       help
+	 This enables AppArmor to mediate applications network use.
+	 This will enable the SECURITY_NETWORK hooks.
+
+config SECURITY_APPARMOR_BOOTPARAM_VALUE
+	int "AppArmor boot parameter default value"
+	depends on SECURITY_APPARMOR
+	range 0 1
+	default 1
+	help
+	  This option sets the default value for the kernel parameter
+	  'apparmor', which allows AppArmor to be enabled or disabled
+          at boot.  If this option is set to 0 (zero), the AppArmor
+	  kernel parameter will default to 0, disabling AppArmor at
+	  bootup.  If this option is set to 1 (one), the AppArmor
+	  kernel parameter will default to 1, enabling AppArmor at
+	  bootup.
+
+	  If you are unsure how to answer this question, answer 1.
+
+config SECURITY_APPARMOR_DISABLE
+	bool "AppArmor runtime disable"
+	depends on SECURITY_APPARMOR
+	default n
+	help
+	  This option enables writing to a apparmorfs node 'disable', which
+	  allows AppArmor to be disabled at runtime prior to the policy load.
+	  AppArmor will then remain disabled until the next boot.
+	  This option is similar to the apparmor.enabled=0 boot parameter,
+	  but is to support runtime disabling of AppArmor, e.g. from
+	  /sbin/init, for portability across platforms where boot
+	  parameters are difficult to employ.
+
+	  If you are unsure how to answer this question, answer N.
+
+config SECURITY_APPARMOR_COMPAT_24
+	bool "Enable AppArmor 2.4 compatability"
+	depends on SECURITY_APPARMOR
+	default y
+	help
+	  This option enables compatability with AppArmor 2.4.  It is
+          recommended if compatability with older versions of AppArmor
+          is desired.
