** Description changed:
[Impact]
On systems with mellanox NICs, udev's NIC renaming races with the mlx5_core
driver's own configuration of subordinate interfaces. When the kernel wins this
race, the device cannot be renamed as udev has attempted, and this causes
systemd-network-online.target to timeout waiting for links to be configured.
This ultimately results in boot being delayed by about 2 minutes.
[Test Plan]
- TODO
+ Since this is a race condition, we need to boot many instances before we see
the issue. The Ubuntu Server team will help coordinate the testing at scale to
confirm the fix.
[Where problems could occur]
The patches effectively make it so that if a interface cannot be renamed from
udev, then the new name is left as an alternative name as a fallback. If
problems occur, it would be related to device renaming, and particularly
related to the devices alternative names.
