Robert Watson 583284e1d7 If the mbuf pointer passed to mac_mbuf_to_label() is NULL, or the tag ... lookup for the label tag fails, return NULL rather than something close to NULL. This scenario occurs if mbuf header labeling is optional and a policy requiring labeling is loaded, resulting in some mbufs having labels and others not. Previously, 0x14 would be returned because the NULL from m_tag_find() was not treated specially. Obtained from: TrustedBSD Project Sponsored by: DARPA, McAfee Research		2004-05-03 23:37:48 +00:00
