Unexpected behaviour you saw

After upgrading systemd from 252 to 253 Wireguard stopped resuming from sleep (suspend, hibernation) cycle. journalctl -u wg-quick@profile.service shows exactly same state as it was before sleep. I get Wireguard back restarting wg-quick service by systemctl restart wg-quick@profile.service.

For networking i use systemd-networkd, systemd-resolved, iwd, wg-quick. Tested with kernels 6.0.8, 6.1.12, 6.2.1.

Downgrading to 252 Wireguard works again as expected.

At first glance, the difference between 252 and 253 system logs is that 253 shows:

  Mar 04 00:01:11 book systemd-networkd[320]: profile: Unmanaging interface.  ← wireguard profile
  Mar 04 00:01:11 book systemd-networkd[320]: enp0s31f6: Unmanaging interface.

The log and your comment in the above suggest that you do not use networkd to manage the WireGuard interface, that is, you have no .network or .netdev file for the WireGuard interface. Right? (If so, I guess this is not a bug in networkd, but you also said downgrading systemd to v252 fixes the issue. hmm...)

Could you enable to generate debugging logs of networkd by creating the following drop-in:

# /etc/systemd/system/systemd-networkd.service.d/override.conf
[Service]
Environment=SYSTEMD_LOG_LEVEL=debug

then, please provide the generated logs.

Thats was the reason, I reported this to systemd. At first I also thought that the problem was something else. But systemd downgrade solved this problem.

Yes, this is intentional to separate handling of wireguard from systemd-networkd. This allows me to easily toggle the wireguard on and off.

Systemd-networkd 252 and 253 debug logs from boot and sleep

Still not sure why it does not work, but should be caused by a39a9ac8065c29330207838b70fe388bde2bc254...

Ah, maybe this one.

I guess, wg service creates routing policy rules, and networkd removes them on after sleep. That should also happen when simply calling networkctl reconfigure UNMANAGED_INTERFACE. Unfortunately, this cannot be fixed (but see the last sentence), as routing policy rules are kind of global setting, and we cannot support multiple services manage it simultaneously.

So, please use ManageForeignRoutingPolicyRules=no in /etc/systemd/networkd.conf.

Let's close this, at least tentatively, as there is nothing we can do.

@andruska Feel free to request to reopen this if ManageForeignRoutingPolicyRules=no does not work for you.

Works, thanks !

Hello. I have a similar problem and I edited the networkd.conf file, but it didn't help. After waking up from sleep mode, I still have to reconnect the VPN. Are there any other tips for fixing this?
