No pppoe connect possible

The netifd commits from December 2023 break my pppoe connection to Deutsche Telekom AG. The connection is established and IP if set, but default route is not added. Looks like netifd crashes silently when the connection is established. Going back to the netifd version from November, 14th (before udebug was added) fixes this issue. The only difference that I can see in the logs is that the new version reports netifd: Network device 'pppoe-wan' link is down immediately after the connection was established while the older version does more stuff.

Did you try a build with the 2023-12-18 update included? It should fix the crashes.

Yes, without success.

Does it create a corefile in /tmp? If so, could you please send it to me, along with your build system .config

commented

There is no such file.

While testing, I tried to restart the network using /etc/init.d/network restart and got some Command failed: Request timed. On a second ssh connection, I saw that the restart process was waiting for ubus call network.interface down { "interface" : "lan" }. Looks like something deadlocks when ppp connects, so there is no crash.

commented

Please try the latest version. It should work now.

Works now, thank you!
