Topics

Please always note your name next to your topic

• [ 👤 djfe] Ubiquiti Airmax

  • #3141
  • The PR hasn't been tested since February. Some of the tests led to the device needing to be recovered.
  • djfe knows an owner of a Nanostation XM but the owner currently doesn't have time for Freifunk either.
  • The PR aimed to introduce a more specific way to controll the flag that fixed it and not change something for all devices of the target.

• [ 👤 djfe] Wireguard VPN doesn't set mtu to value defined in site.conf

  • #3258
  • The wireguard mtu shouldn't matter due to the vxlan(?) interface already having a lower mtu. The 1420 should never be reached
  • Neocturne voiced interest in simplifying our MTU documentation https://gluon.readthedocs.io/en/latest/user/mtu.html#maximum-mtu
  • discussion on potential ways to automize MTU detection -> tricky
    • T_X: there is an RFC for MTU propagation on/between tunnels though: https://www.rfc-editor.org/rfc/rfc4459#section-3.2 (not implemented in batman-adv/fastd/l2tp/wireguard/vxlan)
    • This wouldn't solve that one-to-many VPN taps can only offer one MTU for all devices.
    • T_X: it would allow setting high MTUs on all tunnel interfaces though and signaling/propagating lower MTUs to other, lower encapsulating protocols and down to the final clients via ICMP(v6)

• [ 👤 djfe] ath10k issues on v2023.2.x that weren't present on v2023.1.x

  • ath10k_pci 0000:00:00.0: failed to flush transmit queue (skip 0 ar-state 1): 0
  • Noone remembers this issue, it might be new.
  • It was recommended to open issues on Github to track these (in Gluon as well as upstream in OpenWrt).
  • Maybe rolling back the ath10k firmware to an earlier state fixes this issue.

• [ 👤 djfe] ath9k issues on v2023.2.x that weren't present on v2023.1.x

  • ath: phy0: unsupported hw bitrate detected 0x1b using 1 Mbit
  • read the topic above

• [ 👤 djfe] documentation PRs

  • Feel free to review
  • There is a Github Action that generates a Read the Docs for reviewing: Click "Details" next to the last action "docs/readthedocs.org:gluon — Read the Docs build succeeded!"
