[Fix] networkd should not crash [Test case] Bug was reported to systemd (not accepted because systemd version too old) where a test case is described: https://github.com/systemd/systemd/issues/19648 Lower in the comment you can find the full debug log from networkd. Here you can see the core dump: https://drive.google.com/file/d/1tCKiOSnGkLbx3w9du5_NNepkOQZC_hx7/view?usp=sharing For convenience I also packed the relevant parts of the prod env in a vagrant box showing the issue: vagrant init matijavizintin/networkd- debug After some more testing i noticed that immediately after the route is being advertised, networkd detects the change and crashes with "Assertion 'ifindex' failed at src/network/networkd-link.c:757, function link_get(). Aborting." Steps how it happens: 1. networkd is running 2. frr is started without advertising the aggregated address 3. add aggregated address and reload frr 4. blackhole route is installed and networkd crashes with the error above To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1929122/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
