The Static Analysis tool Scan-Build added that variable o->m_data can be uninitialized when used in context:
m_copydata(n->m_next, 0, tlen, mtod(o, caddr_t) + o->m_len);
This can be fixed my adding a memset with 0 in function m_get right after the memory for this variable is allocated:
mret = SCTP_ZONE_GET(zone_mbuf, struct mbuf);
memset(mret, 0, sizeof(struct mbuf));
