subject: ranges of uid, ranges of gid, jail id objects: ranges of uid, ranges of gid, filesystem, object is suid, object is sgid, object matches subject uid/gid object type We can also negate individual conditions. The ruleset language is a superset of the previous language, so old rules should continue to work. These changes require a change to the API between libugidfw and the mac_bsdextended module. Add a version number, so we can tell if we're running mismatched versions. Update man pages to reflect changes, add extra test cases to test_ugidfw.c and add a shell script that checks that the the module seems to do what we expect.
