Title:
  systemd-networkd: ActivationPolicy ignored in VLANs

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Jammy:
  Fix Released
Status in systemd source package in Kinetic:
  Fix Released

Bug description:
  [Impact]

  The ActivationPolicy property in .network files is ignored for VLANs.

  [Test Plan]

  * On a Jammy machine with an interface named ens3, create the
  following configs:

  $ cat > /etc/systemd/network/10-vlan18.netdev << EOF
  [NetDev]
  Name=vlan18
  Kind=vlan

  [VLAN]
  Id=18
  EOF

  $ cat > /etc/systemd/network/20-vlan18.network << EOF
  [Match]
  Name=vlan18

  [Network]
  Address=10.10.1.1/24

  [Link]
  ActivationPolicy=manual
  EOF

  $ cat > /etc/systemd/network/30-ens3.network << EOF
  [Match]
  Name=ens3

  [Network]
  DHCP=ipv4
  VLAN=vlan18
  EOF

  * Reboot the machine
  * On an affected machine, the vlan18 at ens3 interface will have a configured IP at boot, despite the ActivationPolicy=manual setting in /etc/systemd/network/20-vlan18.network. On a patched machine, the interface should not have a configured IP.

  [Where problems could occur]

  The patch adds a condition where a netdev is not yet ready to be
  created. Specifically, it makes sure stacked netdevs are not created
  before their underlying link is activated. If we saw any problems, it
  would be related to netdev creation.

  [Original Description]

  This has been fixed upstream, see

  Upstream bug: https://github.com/systemd/systemd/issues/22593

  Any chance of a backport of the fix to 22.04?
