| H A D | uipc_mbuf.c | diff 101007 Tue Jul 30 23:51:34 MDT 2002 rwatson Introduce support for Mandatory Access Control and extensible kernel access control. Invoke additional MAC entry points when an mbuf packet header is copied to another mbuf: release the old label if any, reinitialize the new header, and ask the MAC framework to copy the header label data. Note that this requires a potential allocation operation, but m_copy_pkthdr() is not permitted to fail, so we must block. Since we now use interrupt threads, this is possible, but not desirable.
