+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.
