I realize it's not real high on the list of things to fix, but proxy ARP
is still broken in -STABLE. If anyone know the answers to any of these
questions, please drop me a line so I can try fixing it:
1) Can anyone explain the difference between "published" ARP table
entries, and "published (proxy only)" ARP table entries?
2) What purpose does the sin_other parameter of the sockaddr_inarp
structure serve (defined in /usr/include/netinet/if_ether.h, and set
to SIN_PROXY for "proxy only" ARP entries)?
3) How about the significance of the RTF_HOST routing message flag (i.e.
how does an IP "host" route functionally differ from a "net" route with
a /32 netmask)? Or does this only have significance for non-IP routes?
4) What's the purpose of this snippet of code from rtmsg() in
src/usr.sbin/arp/arp.c?
if (doing_proxy) {
if (export_only)
sin_m.sin_other = SIN_PROXY;
else {
rtm->rtm_addrs |= RTA_NETMASK;
rtm->rtm_flags &= ~RTF_HOST;
}
}
Cheers,
