1) "Unknown transfer id" message was because the local variable "tid" is not a transfer id, it is a sequence number - so the check was actually comparing expected vs actual acknowledged sequence number, not TID. It's still a problem if we get the wrong one, but it indicates a lost packet (so we should resend) not a packet that was sent from somewhere else. 2) if the ACK packet has not been received, our retry should involve _resending_ it, not just trying to wait for it again. 3) I have removed the timeout condition for terminating the resend loop, because in practice (assuming both ends have the same timeout setting) all it did was ensure that the loop only ran once. The timeout is supposed to regulate how long we wait for before retrying (it doesn't do this, we wait indefinitely), not how long we wait for before giving up.
Liminix
A Nix-based system for configuring consumer wifi routers or IoT device devices, of the kind that OpenWrt or DD-WRT or Gargoyle or Tomato run on. It's a reboot/restart/rewrite of NixWRT.
This is not NixOS-on-your-router: it's aimed at devices that are underpowered for the full NixOS experience. It uses busybox tools, musl instead of GNU libc, and s6-rc instead of systemd.
The Liminix name comes from Liminis, in Latin the genitive declension of "limen", or "of the threshold". Your router stands at the threshold of your (online) home and everything you send to/receive from the outside word goes across it.
Current status (does it work yet?)
Liminix is pre-1.0. We are still finding new and better ways to do things, and there is no attempt to maintain backward compatibility with the old ways. This will change when it settles down.
In general: development mostly happens on the main branch, which is
therefore not guaranteed to build or to work on every commit. For the
latest functioning version, see the CI system and pick a revision with all jobs green.
In particular: as of July 2023, a significant re-arrangement of modules and services is ongoing:
-
if you are using out-of-tree configurations created before commit
2e50368, especially if they reference things under pkgs.liminix, they will need updating. Look at changes to examples/rotuer.nix for guidance -
the same is intermittently true for examples/{extensino,arhcive}.nix where I've updated rotuer and not updated them to match.
Documentation
Documentation is in the doc directory. You can build it by running
nix-shell -p sphinx --run "make -C doc html"
Rendered documentation corresponding to the latest commit on main
is published to https://www.liminix.org/doc/

There is a #liminix IRC channel on the OFTC
network in which you are welcome. You can also connect with a Matrix
client by joining the room #_oftc_#liminix:matrix.org.
In the IRC channel, as in all Liminix project venues, please conduct yourself according to the Liminix Code of Conduct.
