Julian? This is what I did to make it work for me. A better fix would probably be=20 around the struct proc definition. If fact, you had noted "broken"=20 probably as a memo to fix something here... struct proc *p =3D curproc ? curproc : &proc0; /* XXX broken */ *** ng_ksocket.c.orig Sat Jan 19 11:05:28 2002 --- ng_ksocket.c Sat Jan 19 11:45:23 2002 *************** *** 759,765 **** sopt.sopt_name =3D ksopt->name; sopt.sopt_val =3D ksopt->value; sopt.sopt_valsize =3D valsize; ! sopt.sopt_p =3D p; error =3D sosetopt(so, &sopt); break; } --- 759,765 ---- sopt.sopt_name =3D ksopt->name; sopt.sopt_val =3D ksopt->value; sopt.sopt_valsize =3D valsize; ! sopt.sopt_p =3D 0; error =3D sosetopt(so, &sopt); break; } Florent. -- Florent Parent Viag=E9nie http://www.viagenie.qc.ca To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
