Awesome. Thanks a lot for your efforts, very much appreciated! I'll see that those commits are applied to unstable and bpo in a timely manner once they have been merged upstream.

Bug#969599: systemd: Valid IPv6 addresses and routes discarded erroneously under certain conditions.
Package: systemd Version: 246.4-1~bpo10+1 Followup-For: Bug #969599 Hey folks - I had a productive conversation with one of the upstream authors at https://github.com/systemd/systemd/issues/16719; we think we have found the root cause of this issue. A new version of the upstream PR is being merged and (we hope) will be backported to 246-stable. Hopefully Debian can then integrate it. If it is causing significant issues in the meantime, the commits badd492, 99a2878, 501b09d and 5055072 referenced at https://github.com/systemd/systemd/pull/16725 patch cleanly against the current debian-bpo source and result in a corrected package. Thanks for your help! Colm
Bug#969599: Info received (Bug#969599: systemd: Valid IPv6 addresses and routes discarded erroneously under certain conditions.)
The PR referenced earlier does ameliorate the issue; however I don't think it's a complete fix, as there are worrying messages in the debug log, and there is still nonzero packet loss. I will follow up with upstream. I would encourage Debian users to remain with systemd 245, and not to migrate this version to stable, until this issue is resolved. Colm

That PR patches cleanly against the Debian source; so I'm building a local package version now to test. Will follow up here and with upstream.

Could you test the pull request and verify that this fixes your issue (and ideally also report back to the upstream bug report). Once the PR is merged upstream, we can consider cherry-picking it.

Bug#969599: systemd: Valid IPv6 addresses and routes discarded erroneously under certain conditions.
Package: systemd Version: 246.4-1~bpo10+1 Severity: important Tags: ipv6 Dear Maintainer, The current BPO release of systemd includes a serious regression; valid SLAAC v6 addresses and routes are discarded under certain circumstances. I believe this to be an instance of https://github.com/systemd/systemd/issues/16719 which is possibly fixed by https://github.com/systemd/systemd/pull/16725 The user-visible symptom is that the systems stop responding on their SLAAC-configured v6 addresses until the link is next reconfigured; some time later they drop these addresses again. An extract from the debug log from systemd-networkd follows: note in particular the "Removing address" and "Forgetting address" lines in the log. I think that pull/16725 should be cherry-picked into Debian as soon as possible.
