+config SECURITY_SELINUX
+ bool "NSA SELinux Support"
+ depends on SECURITY_NETWORK && AUDIT && NET && INET
+ select NETWORK_SECMARK
+ default n
+ help
+ This selects NSA Security-Enhanced Linux (SELinux).
+ You will also need a policy configuration and a labeled filesystem.
+ 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
+ 'checkreqprot=' boot parameter. It may also be changed at runtime
+ via /selinux/checkreqprot if authorized by policy.
+
+ If you are unsure how to answer this question, answer 1.
+
+config SECURITY_SELINUX_POLICYDB_VERSION_MAX
+ bool "NSA SELinux maximum supported policy format version"
+ depends on SECURITY_SELINUX
+ default n
+ help
+ This option enables the maximum policy format version supported
+ by SELinux to be set to a particular value. This value is reported
+ to userspace via /selinux/policyvers and used at policy load time.
+ It can be adjusted downward to support legacy userland (init) that
+ does not correctly handle kernels that support newer policy versions.
+
+ Examples:
+ For the Fedora Core 3 or 4 Linux distributions, enable this option
+ and set the value via the next option. For Fedora Core 5 and later,
+ do not enable this option.
+
+ If you are unsure how to answer this question, answer N.
+
+config SECURITY_SELINUX_POLICYDB_VERSION_MAX_VALUE
+ int "NSA SELinux maximum supported policy format version value"
+ depends on SECURITY_SELINUX_POLICYDB_VERSION_MAX
+ range 15 23
+ default 19
+ help
+ This option sets the value for the maximum policy format version
+ supported by SELinux.
+
+ Examples:
+ For Fedora Core 3, use 18.
+ For Fedora Core 4, use 19.
+
+ If you are unsure how to answer this question, look for the
+ policy format version supported by your policy toolchain, by
+ running 'checkpolicy -V'. Or look at what policy you have
+ installed under /etc/selinux/$SELINUXTYPE/policy, where
+ SELINUXTYPE is defined in your /etc/selinux/config.
