Parameter: policy The policy to query. Keyword Parameters/Class attributes: protocol The protocol to match (socket.IPPROTO_TCP for TCP or socket.IPPROTO_UDP for UDP) ports A 2-tuple of the port range to match. (Set both to the same value for a single port) ports_subset If true, the criteria will match if it is a subset of the portcon's range. ports_overlap If true, the criteria will match if it overlaps any of the portcon's range. ports_superset If true, the criteria will match if it is a superset of the portcon's range. ports_proper If true, use proper superset/subset operations. No effect if not using set operations. user The criteria to match the context's user. user_regex If true, regular expression matching will be used on the user. role The criteria to match the context's role. role_regex If true, regular expression matching will be used on the role. type_ The criteria to match the context's type. type_regex If true, regular expression matching will be used on the type. range_ The criteria to match the context's range. range_subset If true, the criteria will match if it is a subset of the context's range. range_overlap If true, the criteria will match if it overlaps any of the context's range. range_superset If true, the criteria will match if it is a superset of the context's range. range_proper If true, use proper superset/subset operations.
