The first patch changes libsepol's internal representation of filename transition rules in a way similar to kernel commit c3a276111ea2 ("selinux: optimize storage of filename transitions") [2]. The second patch then builds upon that and implements reading and writing of a new binary policy format that uses this representation also in the data layout. See individual patches for more details. NOTE: This series unfortunately breaks the build of setools. Moreover, when an existing build of setools dynamically links against the new libsepol, it segfaults. Sadly, there doesn't seem to be a nice way of handling this, since setools relies on non-public libsepol policydb API/ABI.
