Experimental wifi research reports that increased retries (rather than decreased as I originally
thought) improves tcp throughput on multi-hop wifi networks.
Too many retries appears to cause network congestion issues slowing down
links with multiple hops, but reducing this to 1 then caused single links
to have poor performance. Try a rety of 2 as a better compromise.
Unfortunately there doesnt appear to be much flexibility in the various
hardware watchdogs on radios, so setting the watchdog > 60 seconds mostly
doesnt work. So rework the settings to allow for this and that our watchdog
tests must be frequent and quick.
* Watchdog support, initial version.
The watchdog monitors three things:
1. A set of important system daemons.
2. A set of pingable ip addresses.
3. A time the node should reboot everyday.
* Wireguard tunnel support
* Fix wireguard firewall rules
* Add Wireguard tunnels to LQM
* Filter vlans on main bridge
* If you paste a tunnel config into any field, it will auto-populate all fields correctly
* Fix bad password keyword
* Fix bad feeds change
* Fix bad merge
* Initial OpenWRT 23.05.0 merge
* Fix get_rfchannels for new iwinfo format
* Fix initial wlan name
* Move patches to 5.15 from 5.10
* Fix flash write problem on Ubiquiti devices
* Use new ssl patch
* Reduce binary sizes
* Have to have hostapd installed now, even on tiny builds
* Simplify device support
* Revert Mikrotik NAND sysupgrade system.
OpenWRT doesnt really support Mikrotik NAND devices after 2019 and the
new support appeared broken. So reverted to the 2022 mechanism which does
work and avoid upgrade problems.
* Fixes for tiny builds
* More tiny shrinking
* Fix newly added firewall rules
* Update permanent packages
* Update permanent packages
* Support for Nanobeam 2AC (2.4GHz) device. 20MHz channels only.
* Update support
* Add GL.iNet B1300
* Add to radios.json
* Update supported devices
* Dont force the LAN DHCP to run
* Revert CURL SSL test
* Fix radio count when there are no radios
* Switch the lan ports on the gl-b1300
* Add support for GL.iNET Beryl MT1300
* Fix visual lat/lon setting bug
* Make the setup "Save Changes" button also save the location data
* Fix location/map system with geo location fallback
* Recolor
* Fix default bandwidth selection
* Support multi-band radios
* Generic mechanism to set compat version to 1.1
* Switch ethernet ports
* 20 MHz channels only
* Update docs
* Add ham channels to Mediatek chips (20MHz only)
* Automatically update the permpkg list when we upgrade
* Fix 10MHz mode for Ubiquiti AC devices
* Fix tiny builds
* Bump the watch timeout for restarting olsrd
olsrd is reliable these days, and very occasionally this
was restarting it unnecessarily
* Subdomain check too slow for realtime
so now do it in the namecheck service instead.
* Dont commit to VPN address until we set the DNS name
helps supernode setup
The arp cache keeps wifi entries long past them being associated with
the node, so now use wifi assoc list to find nodes, and the arp cache
to get their IPs.
This is an attempt to unify all the station monitoring and make it work
better as one. We're trying to square a circle here somewhat, with taking
steps to kick nodes when problems are detected, but not kick them too quickly
or often in case we're mis-identifing issues.
We've seen these issue manifest themselves which nodes messing VoIP services
as well as resets causing nodes to get into unrecoverable states when there
was no real problems in the first place.
This will probably need to evolve before the next release, but would be good
to get some milage on the new code.
Coverage is handled by modifying firmware state, and the driver stores
the values the first time it is set. When we reset this state might be lost
so it will be reloaded from the firmware. We set the coverage back to 0
so the reloaded value will be the default again.
We also remove a check which can fail incorrectly.
* A scan, especially if we have to do both active and passive, essentially mutes
the radio to AREDN traffic for 10-20 seconds, which isn't good. If the radio is completely
deaf then it doesn't matter, but particularly on the 9K radios we do this when
things are looking a bit dodgy, though not deaf.
* Provide hook to reset ath9k from userspace. This hook is attributed to:
Linus Lüssing <ll@simonwunderlich.de>
* User /sys reset hooks rather than iw scan
* Use LQM information to filter out neighbors we dont care about.
These can cause false rejoin events and degrade the network.
* Only use active station monitor with LQM info.
* Resolve unresponsive node problems with Mikrotik AC devices.
Mikrotik AC devices get into a state where they wont communicate with
non-AC devices .. sometimes. Leaving and rejoinging the network resets
everything. We monitor for this situation and rejoin the network when detected
to resolve the issue.
* Make reporting less chatty
* General station monitor service.
It turns out this station bug is not limited to the ath10k driver, so
make this monitor service wifi generic.
(I've now seen this at both ends of the Mikrotik AC <-> Rocket pair)
* New logs
* Just monitor for now
There appears to be a bug in the ath10k firmware for Mikrotik devices (maybe others)
where a station will associate but only broadcast traffic will be passed - unicast traffic
will fail. This code detects this situation and forces the device to reassociate which
fixes the problem.
On small networks there are not a lot of OLSR name changes. While
dnsmasq watches for changes and updates itself, it will sometimes miss
them. On busy networks this doesnt matter as the next change will catch
it up. But on smaller network (esp. test networks) a missed change can
stop name resolution working for some time. So now, if no changes are
detected for > 60 seconds, we force dnsmasq to reload its tables.
