Say, can anyone tell me which version of the kernel was the last one to
work with Decnet?
Does anyone know what the actual issues are? My friend who does kernel
stuff wants to know.

I have it running on a Raspberry Pi 3B+ with the latest Raspbian Buster release so that
would be running kernel 4.19.50. Debian has not yet officially released Buster (this
coming weekend I believe) so this is somewhat of a pre-release.
Before anyone asks, there are still a couple of issues to track down and I plan to wait
until the official release and some additional testing before putting the code on Github.
John.

I was playing with DECnet in December '17, particularly for MAIL-11 in
VMs running older Ubuntu.
I got it to work well in 2.6.38. (At least I didn't see any issues.)
I got it to sort of work in 3.8. (Some things worked, other things did
not. I don't recall what did and did not.)
Does anyone know what the actual issues are? My
friend who does kernel
stuff wants to know.
I'll see if I can find any notes.

Typical. As soon as I hit send, I find what I was looking for.
Here's what I tweeted in December '17:
"""
I?ve managed to get DECnet working in Ubuntu 9, 10, 11, 12, 13, and 14.
9, 10, and 11 work with everything I know how to test.
12, 13, and 14 partially work. (dnlogin gets PTS / PTY errors.)
14 kernel panics when it pings itself, but other sources seem okay.
"""
There are other details in the thread:

What does "actively support" mean?
I got DECnet working in 2.6.38 with everything I tested.
I got DECnet working to a lesser degree with 3.<something>.
(I can boot VMs and get specific versions if people want them.)
I'm also happy to test things if people want me to.

Version 4.4.x kernels (Ubuntu 16.04.x) and maybe later can be made to work with some
tweaking. See http://rullf2.xs4all.nl/decnet/

Doesn't a DECServer 200 speak LAT rather than DECNet?

Do you mean that in the sense of "it's listed in the documentation as a supported
feature" -- rather than "it can be turned on and if you do that it works"
?

From what I have been able to find out, 2.3.36 was the
last 'official'
release supporting DecNet.
It's good to hear that later release work fine with it (even if it
is to some point).
Maybe it was silently maintained by others later on, who knows?

Thank you for sharing that.
I will file it away for future use.

I think there is a LOT of the Linux kernel that /still/ works by
happenstance.
As in the things that it depends on have not changed, thus it itself
still works.

There appears to some editing that?s done to make sure the code still compiles at
least. On Raspbian between kernel 4.14 (about a year ago) and today?s kernel 4.19, the
timer logic for delayed acks was removed, maybe because it used a kernel API which no
longer exists. Unfortunately, the resulting system paniced as soon as one tried to create
a logical link. (The removed code probably did change the implementation much since
delayed ack is an optional feature in DECnet and Linux only implements a small part of
it).

I finally got around to getting DECnet running on the latest release of Raspbian for the
Raspberry Pi (the 2019-7-10 Buster release). I?ve also done some (very) limited testing on
Debian Buster (both 32- and 64-bit x86 kernels). For anyone who is interested the code is
available at:
