So an interesting first observation for anyone else following this is that under mbuma, the number of bytes available in an mbuf has changed by four due (presumably) to the use of extra space by mbuma: 4.x: MSIZE: 256 MLEN: 236 MHLEN: 212 MINCLSIZE: 213 sizeof(struct m_hdr): 20 sizeof(struct pkthdr): 24 5.x: MSIZE: 256 MLEN: 232 MHLEN: 208 MINCLSIZE: 209 sizeof(struct m_hdr): 24 sizeof(struct pkthdr): 24 So presumably something in pfkey was carefully (or accidentally) designed to assume that some object/content would fit in MLEN or MHLEN that no longer does.
