cvs commit: src/sys/net netisr.c netisr.h src/sys/netinet ip_demux.c ip_input.c ip_var.h

Modified files:
sys/net netisr.c netisr.h
sys/netinet ip_demux.c ip_input.c ip_var.h
Log:
Fix two serious bugs in the IP demux code. First, if ip_mport() m_pullup()'s
an mbuf, the new/modified mbuf is not returned to the caller and the caller
may wind up using a stale/freed mbuf. Second, ip_mport() was not consistently
freeding mbufs which could lead to both a memory leak and a double free.
Reported-by: YONETANI Tomokazu <qhwt+dragonfly-bugs@xxxxxxxxxx> (panic: TCP header not in one mbuf).
