Hello Dan, or anyone else affected, Accepted systemd into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/229-4ubuntu21.29 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-xenial. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B.

[Bug 1877176] Re: 64-char hostname causes dhcp server to reject lease
** Description changed: [impact] a systemd with a 64-character hostname (the maximum hostname length for Linux) will cause a dhcp server to reject its dhcp lease due to passing the invalid hostname in the dhcp lease request. [test case] $ cat /etc/systemd/network/10-ens3.network [Match] Name=ens3 [Network] DHCP=yes - set hostname to 64-char name, e.g.: $ sudo hostnamectl set-hostname a123456789b123456789c123456789d123456789e123456789f123456789g123 restart networkd: $ sudo systemctl restart systemd-networkd check logs: root@a123456789b123456789c123456789d123456789e123456789f123456789g123:~# journalctl -b -u systemd-networkd --no-pager | grep 'DHCP error' May 06 19:01:30 a123456789b123456789c123456789d123456789e123456789f123456789g123 systemd-networkd[737]: ens3: DHCP error: Client failed: Invalid argument + [regression potential] + + Any regression would likely result in failure configuring/processing + dhcpv4 server response, or rejection from the dhcpv4 server. + [scope] this is fixed by commit 9740eae694e93b06658ff3b3045b22b591561e7c which is included in Bionic and later. This is needed only for Xenial. [other info] this is a follow on to bug 1862232, which corrected sd-dhcp-client.c to continue networkd dhcp even if the hostname is invalid, however the older code in Xenial doesn't correctly detect the invalid hostname, so this additional patch is needed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877176 Title: 64-char hostname causes dhcp server to reject lease To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1877176/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
