Final (maybe) ARP breakage plea
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;
}
}

Mick

ARP questions
I'm going to take a crack at cleaning up arp(8), but I need hear some specific answers from someone who's worked with the ARP subsystem: 1) What's the purpose of the sin_other field of a struct sockaddr_inarp (which is either set to 0 or SIN_PROXY)? 2) What's the difference between a "published" or "published (proxy only)" ARP table entry (as reported by arp(8))? 3) Should a proxy ARP entry be a host route (i.e. RTF_HOST is set) as I suspect, or a net route with a /32 netmask, as it strangely seemed to be for "published" entries before arp(8) broke in -STABLE? For either case, why? 4) If I want to perform proxy ARP on directly attached Ethernet network A for a host on directly attached Ethernet network B, do I actually need two ARP table entries--one "published (proxy only)" entry to allow for the proxying on network A, and another ordinary entry (which may in fact be automatically created through the normal ARP mechanism) to actually forward packets to the host on network B?

Out of curiosity, what does 'arp -a' show after the 'arp -s'

Same thing it shows before the arp -s attempt, as does netstat -nr :(
For the record, regular arp -s commands without the pub parameter
(i.e. static ARP cache entries, no proxying) work fine.
I have a couple of other related questions for anyone who knows the
answer, too:
1) Can anyone explain the difference between permanent published ARP
table entries, and permanent published (proxy only) ARP table
entries?
2) What purpose does the RTF_ANNOUNCE (aka RTF_PROTO2) routing message
flag serve? How about the sin_other parameter of the sockaddr_inarp
structure (defined in /usr/include/netinet/if_ether.h)? How do they
relate?
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
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;
}
}
If I remove the last line of code (rtm-rtm_flags = ~RTF_HOST;) and
recompile the arp command, it seems to insert the correct entry
according to netstat -nr, but arp -a doesn't recognize it as
published:
# newarp -s 192.168.54.5 auto pub
using interface ed1 for proxy with address 0:e0:29:32:21:ee
# newarp -a

Note, however, that the code *with* the rtm-rtm_flags = ~RTF_HOST;
worked in earlier incarnations of 3.2-STABLE (it's in 3.2-RELEASE).
