scripts/selinux,selinux: update mdp to enable policy capabilities Presently mdp does not enable any SELinux policy capabilities in the dummy policy it generates. Thus, policies derived from it will by default lack various features commonly used in modern policies such as open permission, extended socket classes, network peer controls, etc. Split the policy capability definitions out into their own headers so that we can include them into mdp without pulling in other kernel headers and extend mdp generate policycap statements for the policy capabilities known to the kernel. Policy authors may wish to selectively remove some of these from the generated policy. Signed-off-by: Stephen Smalley <stephen.smalley.work@gmail.com> Signed-off-by: Paul Moore <paul@paul-moore.com>

selinux: shorten the policy capability enum names The SELinux policy capability enum names are rather long and follow the "POLICYDB_CAPABILITY_XXX format". While the "POLICYDB_" prefix is helpful in tying the enums to other SELinux policy constants, macros, etc. there is no reason why we need to spell out "CAPABILITY" completely. Shorten "CAPABILITY" to "CAP" in order to make things a bit shorter and cleaner. Moving forward, the SELinux policy capability enum names should follow the "POLICYDB_CAP_XXX" format.

selinux: declare data arrays const The arrays for the policy capability names, the initial sid identifiers and the class and permission names are not changed at runtime. Declare them const to avoid accidental modification. Do not override the classmap and the initial sid list in the build time script genheaders. Check flose(3) is successful in genheaders.c, otherwise the written data might be corrupted or incomplete.
