Use mac_biba_label_copy() and mac_mls_label_copy() to implement the
mpo_copy_mbuf_label() entry point for Biba and MLS, respectively. Otherwise, labels in m_tags may not be properly propagated across some classes of mbuf operations. This problem caused these policies to fail-stop the system with a panic. Obtained from: TrustedBSD Project Sponsored by: DARPA, Network Associates Laboratories
