Hello Markus, 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 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 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, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance! ** Changed in: systemd (Ubuntu Xenial) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-xenial -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1727301 Title: 229-4ubuntu20 added ARP option breaks existing bonding interfaces Status in systemd: Fix Released Status in systemd package in Ubuntu: Invalid Status in systemd source package in Xenial: Fix Committed Status in systemd source package in Zesty: Invalid Status in systemd source package in Artful: Invalid Status in systemd source package in Bionic: Invalid Bug description: [Impact] * Setting [Link] MTUBytes= in .network file has a side-effect of overflowing and setting NOARP flag. This is not intended behaviour / regression. * Trying to fix above by setting ARP=on fails to work as tristate is incorrectly acted upon by unconditionally adding NOARP flag * This is a regression in -updates. [Test Case] * Configure an ethernet device with a .network file alone * e.g. Match by mac address and perform DHCP * Add [Link] section to the .network file which changes MTUBytes * Device brought up using this configuration should not have NOAPR flag in the output of iproute link output * Further add ARP=off to that .network file, the link should have NOARP flag * Further add ARP=on to that .network file, the link should not have NOARP flag A test script is attached, that given an interface can abuse it to validate all of the above. [Regression Potential] * These are upstream fixes for ARP= key that are part of zesty and up [Other Info] * Upstream fixes https://github.com/systemd/systemd/commit/b8b40317d0355bc70bb23a6240a36f3630c4952b.patch https://github.com/systemd/systemd/commit/1ed1f50f8277df07918e13cba3331a114eaa6fe3.patch * Original bug report this breaks existing configurations with bonding on upgrading from 229-4ubuntu19 to 229-4ubuntu20 on xenial as bond interfaces are now by default configured without ARP. Hence you suddenly lose network connectivity on upgrade. Very bad for a SRU. Plus adding "ARP=yes" to the Link section of a .network file does not work. Before this update, bond interfaces (specifically 802.3ad) were defaulting to ARP enabled. After the upgrade, they are created with NOARP set on the link. pre-upgrade: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> eth1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> post-upgrade: eth0: <BROADCAST,MULTICAST,NOARP,SLAVE,UP,LOWER_UP> eth1: <BROADCAST,MULTICAST,NOARP,SLAVE,UP,LOWER_UP> bond0: <BROADCAST,MULTICAST,NOARP,MASTER,UP,LOWER_UP> Linux cnode11 4.4.0-97-generic #120-Ubuntu SMP Tue Sep 19 17:28:18 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux To manage notifications about this bug go to: https://bugs.launchpad.net/systemd/+bug/1727301/+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
