- 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 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.
