Subject: Re: ports/151124: OpenBGPD exists if an interface is removed or created

Running "route monitor" shows a RTM_DELETE message on the routing socket =
with no addresses. =20
This appears to match the line in kroute.c
int
dispatch_rtmsg_addr(struct rt_msghdr *rtm, struct sockaddr =
*rti_info[RTAX_MAX],
int connected_only)
{
...
if ((sa =3D rti_info[RTAX_DST]) =3D=3D NULL)
return (-1);
...
}
If the return (-1) is changed to return (0) then OpenBGPD no longer =
exits on changes to the interface.
I'm not sure why there is a empty RTM_DELETE message generated or if it =
is safe to ignore this rather than abort the program....
