Bug#918658: [networkd] crash on resume in 240

[Christopher Martin]

Package: systemd
Version: 240-2
Severity: normal
Tags: patch

After upgrading to systemd 240, networkd started crashing when
resuming from a suspended state. About 30 seconds (give or take) after
resume, systemd restarted networkd and thus brought the network back
up, but the damage had been done.

This is the error from the journal:

systemd-networkd[458]: Assertion 'IN_SET(link->state,
LINK_STATE_CONFIGURING, LINK_STATE_FAILED, LINK_STATE_LINGER)' failed
at ../src/network/networkd-link.c:934, function address_handler().
Aborting.

The same error was reported and fixed upstream as
https://github.com/systemd/systemd/issues/11272, although the reported
circumstances were different. Regardless, fixes have been committed
upstream, and grabbing the latest version of the relevant file
(systemd/src/network/networkd-link.c) and rebuilding systemd fixes the
issue on my machine as well.

I bring this to your attention only because the freeze is near and 241
may be a ways off...

Thanks,
Christopher Martin
