Last time when I sent an email to net@ for comments, I
received only limited feedback.
The New ARP code in my home directory on FreeFall and was
lasted updated on June-8-2007. It was based on then
CURRENT
(7.0) and was tested to be working fine at
that time. A bit more work would be necessary in locking
though. I asked for code review and folks to play with it.
Again, the feedback was really scant.
The code is accessible at
http://people.freebsd.org/~qingli/newarp-06-08-2007/
The question I asked then was "should I move forward?"
I'd be more that happy to resume and be done with it.
I think that breaking the arp code from the routing code need to
proceed.
I see no reason to not have reference counted links from
the routes to
the arp code (for optimisation and compat reasons), but it
should be
self standing.
I'll look at what you have..
it looks very good.
(could do with a few more comments :-)
What I'm trying to do in my current project is add limited
support for multiple routing tables into 6.x or at latest 7.x
I have a 'low impact' version that gives "limited" support.
//depot/user/julian/routing/src/sys/...
(userland utility not in p4 yet)
i.e. you can select from a small number (defined at compile
time) of tables for ipv4 only.. it will do for my purposes,
but should have little impact on the API/ABI. in -current the
requirement for ABI compatibility is not there so I can do
proper rewrite. Which I think would include a rewrite of the
arp code. I like what I see in the code you have done..
It's a bit hard reading you code as patches, is it in P4?
Sorry, the code is not in P4.
I can create a tarball out of all the whole files and
send it to ya if that works?
probably better for me if I make a p4 branch and apply the diffs.
then we have it in p4 :-)

I believe Qing-li (Sp?) did an arp rewrite..
the story is a bit longer - Andre drafted the initial
design, which
i subsequently took over and with a student, Alessandro
Cerri, (I am
Cc-ing him) did a first implementation. This was probably
around 2003.
Then Qing-li (Sp?) took over development of that code -
last i heard
of the code was around last summer.
I think our code at least was based on 4.x so it probably did not
address locking very much (not sure how the routing code
is locked
these days, anyways).
Alessandro is actually around again playing with FreeBSD
so he may
remember more details (it was his thesis, after all!)
cheers
