iwd update to 0.18-1 breaks wireless

mcloaked · 2019-05-13 21:32:28

After updating iwd today to 0.18-1 I found that networking with systemd-networkd is broken. In the logs I have:

$ sudo journalctl -b -1 -u systemd-networkd --no-pager

I found that I had no wireless connection - so I downgraded iwd (0.18-1 -> 0.17-1) and rebooted and it was fine again.

The analogous journal log with iwd 0.17-1 was:

$ sudo journalctl -b -u systemd-networkd --no-pager

May 13 22:07:07 lenovo1 systemd-networkd[528]: wlp4s0: Configured

Here wireless networking is working fine again.

I don't know if there is a work around for iwd 0.18-1, of if a correctly working version of iwd will be added to the repos for versions later than 0.17-1

[Edit} According to the bug report linked below by JasonRyan which suggested a workaround I did change my .network file for the laptop to use the MACAddress= parameter instead of the Name= parameter in the [MATCH] section and this allows systemd-networkd to start up correctly and assign the address to the wireless interface - though it is now named wlan0 instead of the old name wlp4s0 as before. So the problem with iwd/systemd/udev remains and still needs to be worked on.

The log contains now with iwd version 0.81-1:

$ sudo journalctl -b -u systemd-networkd --no-pager

This looks directly related to the report at https://github.com/systemd/systemd/issues/12561 also which implies a systemd/udev problem too.

Edit 2: The workaround in Edit 1 only lasted a limited period before the wireless interface stopped working again - so I still had to downgrade iwd back to 0.71-1 and reboot to get consistent wireless connection that didn't break after some period.

Edit 3: This is the log with iwd 0.81-1 and using the MACAddress match in the systemd-networkd network file - initially the wireless interface was set up fine but then died a few minutes later:

$ sudo journalctl -b -1 -u systemd-networkd --no-pager

and a corresponding iwd log entry at the same time as the systemd-networkd fail:

iwd[488]: MLME notification is missing ifindex attribute

which I believe means a failure of the 4 way handshake - presumably because the link has failed.

Edit 4: I realised from the linked bug report that I might be affected with my iptables firewall - I had restricted the interface to wlp4s0 - so I altered the firewall rules to include wlan0 - and it now works with iwd 0.81-1 - so it is a workaround but need to wait and see if there is any change to the package that allows the new interface names to be used in the MATCH section and not just the name or MACAddress.

I can only add a me too. I'm keeping to 0.17 until I hear news.

The proposed workaround does not restore connectivity for me, and neither does adding an override as mentioned in the comments (in fact I had the override already).

For anyone interested, workaround here works for me:
