Add support for the user to provide a fully custom refpolicy. When this is used, modules aren't disabled anymore and packages do not select refpolicy available modules either. The custom refpolicy must define the full policy explicitly, and must be a fork of the original refpolicy, to have the same build system. This is added to allow users to fully control an SELinux policy, by providing a complete custom policy.

The SELinux Reference Policy project (refpolicy) is a
|
|
complete SELinux policy that can be used as the system
|
|
policy for a variety of systems and used as the basis for
|
|
creating other policies. Reference Policy was originally
|
|
based on the NSA example policy, but aims to accomplish many
|
|
additional goals.
|
|
|
|
The current refpolicy does not fully support Buildroot and
|
|
needs modifications to work with the default system file
|
|
layout. These changes should be added as patches to the
|
|
refpolicy that modify a single SELinux policy.
|
|
|
|
The refpolicy works for the most part in permissive
|
|
mode. Only the basic set of utilities are enabled in the
|
|
example policy config and some of the pathing in the
|
|
policies is not correct. Individual policies would need to
|
|
be tweaked to get everything functioning properly.
