** Summary changed: - wait-network-online timing out on ipv6 only VMs + systemd-networkd-wait-online service times out in IPv6-only environments
** Description changed: - On VMs with IPv6 only networking, systemd-networkd-wait-online times out - during boot. To reproduce, get the latest questing image from - https://cloud-images.ubuntu.com and run: + [Impact] + In an iSCSI boot scenario within an IPv6-only environment, the link remains in the "configuring" state when the DHCPv6-assigned address conflicts with an already configured address. + Although network connectivity works as expected, this condition causes the systemd-networkd-wait-online service to time out during the boot process. - qemu-system-x86_64 \ - -snapshot -nographic -machine q35,accel=kvm \ - -smp 2 -m 2G \ - -netdev id=net0,ipv4=off,ipv6=on,type=user \ - -device virtio-net-pci,netdev=net0 \ - -drive if=virtio,format=qcow2,file=/tmp/questing-server-cloudimg-amd64.img + [Fix] + This issue has been resolved upstream. + https://github.com/systemd/systemd/pull/37916 + + [Test Plan] + 1. Set up an IPv6-only environment with iSCSI boot. + 2. Run the networkctl command and verify that no links remain in the "configuring" state. + + [Where problems could occur] + The commit introduces a new member variable to track this specific condition and updates the link status accordingly. + If any regressions occur, the link status may become incorrect, potentially causing unexpected behavior in the systemd-networkd-wait-online service. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2115418 Title: systemd-networkd-wait-online service times out in IPv6-only environments To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/2115418/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
