Probably. Now this problem located on src/sys/netinet/udp_usrreq.c:719 And source have similar new problem on src/sys/netinet/udp_usrreq.c:757 Short description both problem: Socket may be "temporary" connected on src/sys/netinet/udp_usrreq.c:704, if addr != NULL And socket don't disconnected by error condition and return. > http://www.FreeBSD.org/cgi/query-pr.cgi?pr=8206 P.S. Now I don't have test system for experimental checking this (and other errors), because test system demounting few years ago. But source code on <http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/netinet/udp_usrreq.c?annotate=1.100>; have this problem. P.P.S. On src/sys/netinet/udp_usrreq.c:759, function make "goto release" without restore splx(s), if addr != NULL. -- Sorry for my bests English. Serguei E.
