Title:
Assertion 'link->state == LINK_STATE_SETTING_ROUTES' failed at
../src/network/networkd-link.c:697, function link_enter_configured().
Aborting.
Status in systemd package in Ubuntu:
Fix Released
Status in systemd source package in Xenial:
Fix Released
Bug description:
[Impact]
* networkd aborts, whilst failing to update address for a
failed/lingering link.
[Test Case]
* Sending invalid or flooding the system with RA requests typically
reproduces this bug.
Examples:
https://github.com/systemd/systemd/issues/2977
https://github.com/systemd/systemd/issues/2228
https://github.com/systemd/systemd/issues/3204
[Regression Potential]
* This patch is a cherrypick form upstream, which adds additional
checks to prevent attempts to configure a link which is not ready yet.
This patch is present in v230+ thus the code path should have been
well exercised in Ubuntu by now, in later releases.
Otherwise, the code behaviour is not changed. Simply, in case of
broken links, address update is not attempted and error is returned.

[Other Info]
* Original bug report
Hi,
the net of my PC is configured via systemd-networkd + systemd-
resolved. And last two weeks I faced with the problem when my net is
down. "journalctl -xe" helped to detect this issue:
окт 19 13:36:22 work-pc systemd-resolved[10417]: Failed to read DNS servers
for interface enp3s0, ignoring: Argument list too long
окт 19 13:36:22 work-pc kernel: e1000e: enp2s0 NIC Link is Down
окт 19 13:36:25 work-pc systemd-networkd[2200]: enp2s0: Gained carrier
окт 19 13:36:25 work-pc systemd-networkd[2200]: Assertion 'link->state ==
LINK_STATE_SETTING_ROUTES' failed at ../src/network/networkd-link.c:697,
function link_enter_configured(). Aborting.
окт 19 13:36:25 work-pc systemd-resolved[10417]: Failed to read DNS servers
for interface enp3s0, ignoring: Argument list too long
When I type "systemctl restart systemd-networkd", nothing happens, net
is still down. When I type "systemctl restart systemd-resolved", it's
all starting to work fine, as usual.
A little bit of googling gave me this bug in systemd bugtracker:
https://github.com/systemd/systemd/issues/2228
and this PR: https://github.com/systemd/systemd/pull/3224
Looks like this issue was fixed in systemd-230. So can you backport
this patch to systemd package?
I can patch it and test it myself, actually, but it would be really
nice if there will be no need to.
