+config SECURITY_SELINUX

+        depends on SECURITY && NET && INET
+        default n
+        help
+          This selects NSA Security-Enhanced Linux (SELinux).
+          You will also need a policy configuration and a labeled filesystem.
+          You can obtain the policy compiler (checkpolicy), the utility for
+          labeling filesystems (setfiles), and an example policy configuration
+          from <http://www.nsa.gov/selinux/>.
+          If you are unsure how to answer this question, answer N.
+config SECURITY_SELINUX_BOOTPARAM
+        bool "NSA SELinux boot parameter"
+        depends on SECURITY_SELINUX
+        default n
+        help
+          This option adds a kernel parameter 'selinux', which allows SELinux
+          to be disabled at boot.  If this option is selected, SELinux
+          functionality can be disabled with selinux=0 on the kernel
+          command line.  The purpose of this option is to allow a single
+          kernel image to be distributed with SELinux built in, but not
+          necessarily enabled.
+          If you are unsure how to answer this question, answer N.
+config SECURITY_SELINUX_BOOTPARAM_VALUE
+        int "NSA SELinux boot parameter default value"
+        depends on SECURITY_SELINUX_BOOTPARAM
+        range 0 1
+        default 1
+        help
+          This option sets the default value for the kernel parameter
+          'selinux', which allows SELinux to be disabled at boot.  If this
+          option is set to 0 (zero), the SELinux kernel parameter will
+          default to 0, disabling SELinux at bootup.  If this option is
+          set to 1 (one), the SELinux kernel parameter will default to 1,
+          enabling SELinux at bootup.
+          If you are unsure how to answer this question, answer 1.
+config SECURITY_SELINUX_DISABLE
+        bool "NSA SELinux runtime disable"
+        depends on SECURITY_SELINUX
+        default n
+        help
+          This option enables writing to a selinuxfs node 'disable', which
+          allows SELinux to be disabled at runtime prior to the policy load.
+          SELinux will then remain disabled until the next boot.
+          This option is similar to the selinux=0 boot parameter, but is to
+          support runtime disabling of SELinux, 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_SELINUX_DEVELOP
+        bool "NSA SELinux Development Support"
+        depends on SECURITY_SELINUX
+        default y
+        help
+          This enables the development support option of NSA SELinux,
+          which is useful for experimenting with SELinux and developing
+          policies.  If unsure, say Y.  With this option enabled, the
+          kernel will start in permissive mode (log everything, deny nothing)
+          unless you specify enforcing=1 on the kernel command line.  You
+          can interactively toggle the kernel between enforcing mode and
+          permissive mode (if permitted by the policy) via /selinux/enforce.
+config SECURITY_SELINUX_AVC_STATS
+        bool "NSA SELinux AVC Statistics"
+        depends on SECURITY_SELINUX
+        default y
+        help
+          This option collects access vector cache statistics to
+          /selinux/avc/cache_stats, which may be monitored via
+          tools such as avcstat.
+config SECURITY_SELINUX_CHECKREQPROT_VALUE
+        int "NSA SELinux checkreqprot default value"
+        depends on SECURITY_SELINUX
+        range 0 1
+        default 1
+        help
+          This option sets the default value for the 'checkreqprot' flag
+          that determines whether SELinux checks the protection requested
+          by the application or the protection that will be applied by the
+          kernel (including any implied execute for read-implies-exec) for
+          mmap and mprotect calls.  If this option is set to 0 (zero),
+          SELinux will default to checking the protection that will be applied
+          by the kernel.  If this option is set to 1 (one), SELinux will
+          default to checking the protection requested by the application.
+          The checkreqprot flag may be changed from the default via the

+          via /selinux/checkreqprot if authorized by policy.
