Description of problem:
NSD4 (http://koji.fedoraproject.org/koji/buildinfo?buildID=706713) requires some changes to selinux-policy. (I know the build is for EL7, but one for Fedora is coming too)

To make NSD4 work properly, I've executed the following commands:


chcon -t nsd_exec_t /sbin/nsd-checkconf
chcon -t nsd_exec_t /sbin/nsd-checkzone
chcon -t nsd_exec_t /sbin/nsd-control  
chcon -t nsd_exec_t /sbin/nsd-control-setup


and created (thanks to audit2policy) the following policy:


module mypol 1.0;

require {
	type tmp_t;
	type nsd_t;
	class capability net_admin;SELinux policy changes to make NSD4 work
	class dir { write create add_name };
	class file { write create open };
}

#============= nsd_t ==============
allow nsd_t self:capability net_admin;
allow nsd_t tmp_t:dir { write create add_name };
allow nsd_t tmp_t:file { write create open };


with those changes, it works
