In reply to the original post:
Dear all:
When the new link layer framework was introduced in 8.0, one of our ATM
stacks, netnatm, was left behind. As a result, it neither compiles nor runs
in 8.x and 9.x. This e-mail serves two purposes:
(1) To solicit a volunteer who can work on the netnatm stack in 9.x, with
potential merge to 8.x, to get it back to functionality before 9.0 ships.
This is the preferred course of action.
(2) To serve as notice that if we can't find a volunteer to do this, we will
remove netnatm and associated parts from the tree in 9.0 since they'll have
gone one major version neither compiling nor running. This is the fallback
plan.
I'm in no great rush to remove netnatm, having spent quite a bit of time
making it work in our MPSAFE world order a couple of years ago. However, the
code is bitrotting and requires urgent attention if it's going to work again
easily (the stack is changing around it, and because netnatm doesn't build,
it will get only cursory and likely incorrect updates). I'm happy to help
funnel changes into the tree from non-committers, as well as answer questions
about the network stack, but I have no hardware facilities for debugging or
testing netnatm changes myself, nor, unfortunately, the time to work on the
code.
In order to provide further motivation for potentially interested parties,
here's the proposed six-month removal schedule:
28 July 2010 - Notice of proposed removal
28 October 2010 - Transmit of notice of proposed removal
28 January 2011 - Proposed removal date
This schedule may be updated as the 9.0 release schedule becomes more clear,
or if there are obvious signs of improvement and just a couple more months
would get it fixed :-). And, if worst comes to worst and we can't find a
volunteer, the code will live on in the source repository history if there's
a desire to rejuvenate it in the future.
I would request two things:
1) the extra couple of months; this will not prevent the evitable removal
yet only defer it.
2) If anyone of you is using (or want to be able to (continue to) use) NATM
or can test things, I re-enabled it with most of the code in HEAD and
the patch is available for 8,x as well but need to work with somoene
to make sure it'll really work. I am willing to spend more time on it
if you send me an email.
Best Regards,
Bjoern

New Revision: 216466
URL: http://svn.freebsd.org/changeset/base/216466
Log:
Bring back (most of) NATM to avoid further bitrot after r186119.
Keep three lines disabled which I am unsure if they had been used at all.
This will allow us to seek testers and possibly bring it all back.
If you have the ability to test (on 8.x or HEAD) or are using NATM,
please get in contact with me.
Discussed with: rwatson
MFC after: 7 weeks
