> Can this be backported to Focal? If I'm understanding the upstream bug correctly, this only affects those using a really large number of interfaces and/or vlans and/or bridges on a single system, and in that situation this can be worked around just by increasing the socket receive buffer size for systemd-networkd.socket, right?
If that's the case, I don't really think this is something valid for backporting; the buffer increase is just delaying the ENOBUF, and if more interfaces are added it may still happen. I believe the buffer size adjustment is a configuration issue for anyone using such a large number of interfaces. However, if I've misunderstood the bug or patch, or if there are problems with my evaluation of it, please provide specific steps and/or config to reproduce the problem, so we can evaluate what's needed for backporting to focal. For now, marking as wontfix. ** Changed in: systemd (Ubuntu Focal) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912331 Title: Many interfaces lead to "kernel receive buffer overrun" To manage notifications about this bug go to: https://bugs.launchpad.net/systemd/+bug/1912331/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
