OpenWRT 23.05 802.11r + EAP

Getting 802.11r Fast Transition working with WPA(2)-Enterprise is quite painful. There is information on the forums, but things have changed quite a bit during the last few years. These are notes mostly for my own benefit.

Tricky bits as of OpenWRT 23.05 (in Luci "WLAN roaming" tab of wireless network settings):

  • NAS Id should be set to something unique, like the name of the AP.
  • Mobility domain defaults to a sane value. Leave it empty.
  • Reassociation deadline's default of 1000 is bad. Apparently Cisco uses 20000 here, setting that appears to be helpful.
  • FT Protocol "Over the air" is the good setting.

If you're using WPA2-PSK, check "Generate PMK locally" and you're done. Save&apply and it should just work.

Get a user's Twitter likes (favorites) in twint JSON format using the official API
#!/usr/bin/env python3
# pylint: disable=invalid-name,line-too-long,broad-except
"""
Returns as many liked tweets from given Twitter user
as the API allows. Output format is compatible with twint
(https://github.com/twintproject/twint) JSON output
(i.e. one JSON object per line, _not_ wrapped into an array).
This uses the official API since likes seem to be inaccessible
without logging in at the moment.

Instructions and patch for enabling wpa_supplicant PTK0 rekey issue workaround

My Intel AX201/Ubuntu 20.04 was getting hit hard by the PTK0 rekey issue: traffic would slow down to dialup speeds after the first rekey. Fixing this and having the fix work with NetworkManager requires recompiling wpa_supplicant with a patch. Steps:

  1. Get current Ubuntu/Debian source: apt-get source wpasupplicant
  2. Get latest version: git clone git://w1.fi/hostap.git
  3. Install packaged version config: cp wpa-2.9/debian/config/wpasupplicant/linux hostap/wpa_supplicant/.config
  4. Save below patch to supplicant.patch and apply: patch -p1 < supplicant.patch
  5. Rebuild supplicant: cd hostap/wpa_supplicant && make
  6. Move original binary aside (as root): mv /sbin/wpa_supplicant /sbin/wpa_supplicant.orig

Shell script to set battery charge limits on Thinkpads with post-2018 kernels (acpi_call kernel module not needed)
#!/bin/bash
# On post-2018 kernels the Thinkpad charge threshold mechanism has
# been included in the thinkpad-acpi module. Hence the tpacpi-bat
# tool (and the acpi_call kernel module) are no longer necessary;
# you can just set the values in sysfs.
# Stop charging at this percentage
STOP_AT=80
# Start charging at this percentage
