Support XKISS TNCs and enhance stack to use it
Summary
XKISS is a protocol enhancement to TNCs which provides, among other things, notifications when packets have actually been transmitted over the air. This notification feature can be useful for improving the throughput and behavior of the station on the network.
This is a placeholder task for such a feature.
Figure out why T3 isn't being started during idle periods
T3 should be started during idle periods to periodically poll the other side is there. However it isn't running.
Go figure out why and fix it.
(ax25 status dumps the timer state...)
[ax25] [aprs] aggregate messages to destination ID, BEACON, INFO and populate a cache of last seen ID strings
Right now various BBS nodes on 145.090 are beaconing out INFO, ID, BEACON frames. It would be nice to cache these (and maybe NODES too?) locally so it's easy to dump out the current immediately visible ax25 network state.
Make this compile/run on linux
This needs a few tweaks to compile/run on linux:
- no funopen() support on earlier linux's, so need to check for funopen and set HAVE_FUNOPEN appropriately
- it'll pull in format.c if it's not set (for _format), so conditionally include that
- need to update the include guards on the include files to not clash with system headers - eg errno.h needs to be KA9Q_ERRNO_H, not just _ERRNO_H
- srandomdev isn't on linux - need to detect on it and use srandom(time()) instead.
Figure out why the same 7 packets keep being repeated over and over again in transmit
The ka9q (and n0ary-bbs) stack handles back to back RR and REJ's very poorly.
Notably, RNR/REJ can cause inv_rex() to be called, clearing axp->unack, and thus queuing a new set of transmit attempts. If the sender sends a bunch of RR/RNR/REJ's in a burst in response to sent traffic (eg if there's no T2 timer support, or it's too short, or it's broken!) then this results in the stack making some pretty poor decisions about what to send and when.
So, whilst I'm adding T2 support for data/control paths to KA9Q, it may be interesting to track when a full burst was sent and not re-trigger it until T1 expires and/or we receive an S/I frame with an updated sequence number. That way even if T2 expires and we're ready to send some more data, we won't be sending another packet burst if we've already /sent/ a packet burst.
Extend the ax25 timers, maxpacket, etc fields to be per interface
right now a bunch of ax25 configuration parameters are global rather than per interface. This has the unfun side effect of making it less interesting to run a single ka9q instance with multiple TNCs spanning 1200 VHF, 9600 baud UHF and 300 baud HF.
The easiest way to address this would be to move a bunch of configuration to be per interface and configured using ifconfig. it means ifconfig will need to grow some per-linklevel state that gets copied over into the ax25 control block upon creating a connection but i think it's doable.
fix up unproto ax25 socket handling lifecycle - stuff blocks forever on close/shutdown, etc
The ax25 UI socket handling is broken - notably there's only a single UI socket - Axui_sock - used for listening for AX25 ui frames.
The problem is that it's a special case with a special queue (Bcq) with special cases for being woken up (via ksignal). The normal close path (kshutdown, close_s in sock.c) doesn't see this as a "connected" socket, so it doesn't /actually/ close the socket properly and it doesn't signal the owner that it should unblock and start failing things.
Sequence number logic and retransmissions
Here's a fun one.
If maxframes is set to 8, retransmission bursts that SHOULD have been ACKed are .. not treated as ACKed.
Here's an example.

- I send a burst
- I get an ACK RR for all of the frames
- I already had a poll queued, so I poll RR
- N0ARY sends back a poll response with the correct n(r)
- .. but somewhere the transmit logic gets confused and thinks it has to send it again.

.. it's possible somewhere the ACK'ing logic for sequence numbers is wrong.. need to go digging.
For now I'll set maxframes locally to 7 instead of 8 so I can get data out!
Using "disconnect X" / "reset X" / "close X" from the console doesn't close the session
When a session disconnects via the remote end sending a disconnect/eof, the telnet process used as part of ax25 connect will correctly close a session.
However if it's aborted locally the session socket gets closed down, but the session itself doesn't go away.
Here's what I see in the console.

Outside Connectivity?
Ok, I was able to get KA9Q running in DOS with all the important stuff running. Came back here to see if I could do the same with the KA9Q for UNIX. I am able to login with the loopback only here in UNIX. With DOS, I can get the ethernet (FTP resident driver) to talk to my LAN and do FTP/TELNET. I was also able to get it to talk to my TNC over serial/KISS. With the UNIX code again I only have loopback. I tried reading the source in the unix folder, but alas I am not much of a programmer beyond stuff I do for physics algorithms. So I am not sure if there is some sort of tun/tap or the ability to talk to world via a UNIX socket. So some very minimal bootstrap doc would be super helpful. I have the rest of the DOS documents for this package.
I also built Phil's source here in gethub with IN DOS with a Borland C compiler. It functions exactly the same as the version here.
I ended up using an older version because Phil's latest seems to be missing the connection between the "attach asy" driver and the ax.25 stack. In the older version, I initiate the KISS/AX.25 radio port by doing:
DOS: attach asy 0x3f8 4 ax25 tnc0 2048 9600
UNIX: attach asy /dev/cuau0 ax25 tnc0 2048 9600
In Phil's Github version (and your fork of that source I presume), I get the error:
Mode ax25 unknown for interface tnc0,
but I can replace the ax25 with "slip" and I takes it with no error. This leads believe I could setup some sort of slip link with the outside world. However, I am thinking your folks already have other options for connectivity.
I would love to play with this some more.

Sending a 7 packet burst and a poll ends up potentially causing a REJ to be sent in response
the following sequence of packets seems like a popular one when watching BBS traffic, and it leads to some pretty bad behaviour.

Now, note it sent a 7 packet burst (which is good!) and then it sent the I frame with the first sequence number in the burst again.
I sent a RR n(r)=3 to ACK everything up to 2 (which is good) but then since I got a frame with a seqno of 4, I assumed that I hit a sequence number issue and sent a REJ (which is bad.) It then gets stuck in its retransmission loop because it thinks the ACK means "send more data", but the REJ causes it to also send more data, so it double sends a whole lot of the same crap:

The "sending too much crap" is a separate bug that'll end up being fixed when transmit delay (T2) is introduced. This bug is how it decides to send that final poll frame and the sequence number it's using to do so.
setting the ax25 socket address to an invalid AX25 address doesn't error out quickly
I've noticed that connecting to invalid length ax25 addresses doesn't fail in the socket routines, it fails when creating ax25 packets.
eg:
connect tnc0 PKTCHAT-1
PKTCHAT-1 is too long, which should fail when doing kbind, kconnect, ksendto, etc. However it isn't caught there!
