I went through the [test case] steps before and after the -proposed
update. Should I simply explicitly mention me going trough it or do I
need to copy it again?

  [regression potential]

  this adjusts the length of the specific netlink parameter, so any
  regression would likely relate to incorrectly setting the persistent
  keepalive interval parameter, or failure to set the parameter.

  [scope]

  this is needed only for Bionic.

  this was fixed upstream in commit
  7d0b26a027118ca063780421cb31c74e9d2664ee which was first included in
  v240, so this is fixed in Eoan and later.  Xenial does not include
  support for wireguard, so this does not apply there.

  [original description]

  This morning, our 2 Bionic machine configured with the wireguard's PPA
  and using systemd-networkd to configure the wireguard tunnel started
  misbehaving. Why this started just now is unclear ATM but their dmesg
  was filled with this:

Hello Simon, or anyone else affected,

Accepted systemd into bionic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/237-3ubuntu10.41 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-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. 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!

Bug description:
  [impact]

  systemd-networkd uses incorrect netlink attribute length for
  wireguard's persistent keepalive interval, which logs error messages
  from the kernel, and may incorrectly set the parameter.

  [test case]

  Only 1 Bionic VM is required to reproduce the problem:

  $ lxc launch images:ubuntu/bionic --vm -c security.secureboot=false foo
  $ sleep 10 # allow booting
  $ lxc exec foo -- apt install -y software-properties-common
  $ lxc exec foo -- add-apt-repository -y ppa:wireguard/wireguard

  [regression potential]

  this adjusts the length of the specific netlink parameter, so any
  regression would likely relate to incorrectly setting the persistent
  keepalive interval parameter, or failure to set the parameter.

  [scope]

  this is needed only for Bionic.

  this was fixed upstream in commit
  7d0b26a027118ca063780421cb31c74e9d2664ee which was first included in
  v240, so this is fixed in Eoan and later.  Xenial does not include
  support for wireguard, so this does not apply there.

  [original description]

  This morning, our 2 Bionic machine configured with the wireguard's PPA
  and using systemd-networkd to configure the wireguard tunnel started
  misbehaving. Why this started just now is unclear ATM but their dmesg
  was filled with this:

this is fine to include, it's clearly correct (I checked both the
upstream kernel as well as wireguard-linux-compat from the ppa, and the
param is u16 in both places)

I assume you can easily reproduce this, just by configuring a non-zero
WireGuardPeer.PersistentKeepalive value?  If so, can you update the SRU
template [test case] section?  That will need to be filled out before
the patch can be sru'ed.

>
https://github.com/systemd/systemd/commit/624a47694cad4c87b2e807c32db656f3e9d679c5

I don't think this is needed, it only changes use of
sd_netlink_message_append_data() to
sd_netlink_message_append_sockaddr_in() - or _in6() - which aren't
included in the bionic version of systemd, and from looking at their
upstream addition they don't seem to functionally change anything, just
add more checking (and simplify the call params).  Unless you can point
out what the patch specifically fixes, I think we can leave this patch
out.

  Folks in #systemd mentioned
  https://github.com/systemd/systemd/issues/11575 which points to 2
  commits missing from Bionic's systemd version:

  
https://github.com/systemd/systemd/commit/7d0b26a027118ca063780421cb31c74e9d2664ee
  
https://github.com/systemd/systemd/commit/624a47694cad4c87b2e807c32db656f3e9d679c5

  Focal's systemd have the above commits. Would it be possible to
  backport those 2 commits to Bionic?

Bug description:
  This morning, our 2 Bionic machine configured with the wireguard's PPA
  and using systemd-networkd to configure the wireguard tunnel started
  misbehaving. Why this started just now is unclear ATM but their dmesg
  was filled with this:
