Bug description:
[Impact]
* Incomplete cherrypick of ARP functionality in networkd resulted in
an undesired side-effect, specifically NOARP flag started to be
applied unconditionally, specifically when it should not have,
resulting in loss of network connectivity.
* This is a regression in -updates.
[Test Case]
* Configure a bond using networkd
* Upgrade
* Make sure NOARP flag is not set on the interfaces / bond
[Regression Potential]
* This is an upstream fix for this issue.
[Other Info]
* Upstream fix
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>
