The caller `sys/netinet/tcp_output.c` ``` 1444 ip6->ip6_hlim =3D in6_selecthlim(inp, NULL); ``` The callee, `sys/netinet6/in6_src.c`: ``` 843 int 844 in6_selecthlim(struct inpcb *inp, struct ifnet *ifp) 845 { 846=20 847 if (inp && inp->in6p_hops >=3D 0) 848 return (inp->in6p_hops); 849 else if (ifp) 850 return (ND_IFINFO(ifp)->chlim); 851 else if (inp && !IN6_IS_ADDR_UNSPECIFIED(&inp->in6p_faddr)) { ... } ``` The line 850 of should never hit as `ifp` is NULL, the backtrace also shows that clearly. That is quite odd ... Is it possible that kgdb report the wrong line number= ? --=20 You are receiving this mail because: You are the assignee for the bug.=
