The problem is the TCP protocol value is not set in the xt_socket structure passed back to netstat routines. See horrid workaround below (one line). The value returned in the structure looks rather like an address or left over un-inited garbage. >How-To-Repeat: Type netstat with TCP connections active >Fix: My dirty but quick fix, to netstat/inet.c: oxig = xig = (struct xinpgen *)buf; for (xig = (struct xinpgen *)((char *)xig + xig->xig_len); xig->xig_len > sizeof(struct xinpgen); xig = (struct xinpgen *)((char *)xig + xig->xig_len)) { if (istcp) { tp = &((struct xtcpcb *)xig)->xt_tp; inp = &((struct xtcpcb *)xig)->xt_inp; so = &((struct xtcpcb *)xig)->xt_socket; /* JRD */ so->xso_protocol = proto; /* correct uninited value */ /* JRD */ } else { inp = &((struct xinpcb *)xig)->xi_inp; so = &((struct xinpcb *)xig)->xi_socket; } /* Ignore sockets for protocols other than the desired one. */ if (so->xso_protocol != proto) continue; >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
