+ 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.

+ help
+ This option determines whether the new secmark-based network
+ controls will be enabled by default. If not, the old internal
+ per-packet controls will be enabled by default, preserving
+ old behavior.
+
+ If you enable the new controls, you will need updated
+ SELinux userspace libraries, tools and policy. Typically,
+ your distribution will provide these and enable the new controls
+ in the kernel they also distribute.
+
+ Note that this option can be overridden at boot with the
+ selinux_compat_net parameter, and after boot via
+ /selinux/compat_net. See Documentation/kernel-parameters.txt
+ for details on this parameter.
+
+ If you enable the new network controls, you will likely
+ also require the SECMARK and CONNSECMARK targets, as
+ well as any conntrack helpers for protocols which you
+ wish to control.

- This enables the NSA SELinux Multi-Level Security (MLS) policy in
- addition to the default RBAC/TE policy. This policy is
- experimental and has not been configured for use. Unless you
- specifically want to experiment with MLS, say N.
+ 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 Fedore Core 5 and later,
+ do not enable this option.
+
+ If you are unsure how to answer this question, answer N.

+ 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.
