Bug description:
  Currently resolvconf and systemd-networkd don't ensure DNS has been
  configured before allowing network-online.target to be reached.

  This was discussed in https://launchpad.net/bugs/1636912 however it
  was not a regression since there aren't any users of networkd + DNS
  early in boot at this time, it was requested that we move this DNS
  issue to a separate bug.

  [SRU]
  Fix: switch resolvconf.service to run Before=network-pre.target and add 
Wants=network-pre.target.  Add a Before=network-online.target to 
systemd-networkd-resolvconf-update.service to ensure we update /etc/resolv.conf 
with DNS config prior to reaching network-online.target.

  Regression potential: Low. networkd is not widely being used outside
  of netplan/snappy in xenial.

  Test Case:
    lxc launch ubuntu-daily:xenial x1
    lxc exec x1 /bin/bash

    # make sure you're on systemd-229-4ubuntu17
    apt update && apt install -y systemd

    # enable networkd and netplan
    apt install -y nplan

    # the order should be:

  2. systemd-networkd-wait-online.service:  systemd[1]: Starting Wait for

  3. systemd-networkd-resolvconf-update.service: systemd[1]: Started Update 
resolvconf for networkd DNS.
  4. network-online.target: systemd[1]: Reached target Network is Online.

  === BAD OUTPUT ===

In neither case did I end up with an unconfigured /etc/resolv.conf , but
this does at least demonstrate the capacity for the race (and its
resolution).  Marking verified.

I've tested this now in a 16.10 VM, and I can't verify this SRU because
I can't confirm the buggy behavior.  Adjusting the journalctl command
for changed unit names in 16.10, I get:

Running the test case from the bug description for a yakkety container,
this is the behavior I see with the yakkety-updates version of nplan:

That doesn't appear to match the expected "bad" behavior.  Ryan, do you
know what I'm missing here?

I'm assuming it's a container permissions error, and give a VM a try.

I've moved the systemd-resolved issue for unit ordering out of this
bug/SRU into a new one so we can finish out this SRU and handle this
last change to systemd-resolved separately.

[Touch-packages] [Bug 1649931] Re: systemd-networkd needs to ensure DNS is up before network-online.target

[Ryan Harper]

@racb

I verified systemd 229-4ubuntu17 with both ifupdown and networkd
configuration.

The specific packages and features is somewhat complicated due to
the different scenarios and change in networking behavior in yakkety+

I've attached a chart with details.  Also viewable here:

http://paste.ubuntu.com/24140363/

The tl;dr is for Xenial, we won't need another SRU as 
systemd-resolved is not enabled to manage DNS, rather
resolvconf still controls /etc/resolv.conf

In Yakkety+, systemd-resolved ends up owning /etc/resolv.conf
and employs resolvconf to register itself therein.

Which package and what versions please? This shows up as green in

[Touch-packages] [Bug 1649931] Re: systemd-networkd needs to ensure DNS is up before network-online.target

[Ryan Harper]

For yakkety resolvconf update;  I've updated the SRU test-case to
include a more general netplan config for bringing up ethernet devices;
the previous version only worked on lxd (or instances with devices named
eth0).

With the above change; it looks like yakkety/zesty (due to running
systemd-resolved instead of resolvconf service) need an update to the
systemd-resolved service the instance is configured to use networkd
insteadof ifupdown to ensure that systemd-resolved runs *before*
network-online.target.

 # On kdbus systems we pull in the busname explicitly, because it

This makes things more complicated for this SRU;  yakkety/zesty will
need an updated systemd; the resolvconf portion of this SRU (for
yakkety) is still OK but it's not sufficient to achieve the goal of
ensuring DNS is functional *before* we reach 'network-online.target'.

[Touch-packages] [Bug 1649931] Re: systemd-networkd needs to ensure DNS is up before network-online.target

[Ryan Harper]

** Description changed:

  Currently resolvconf and systemd-networkd don't ensure DNS has been
  configured before allowing network-online.target to be reached.
  
  This was discussed in https://launchpad.net/bugs/1636912 however it was
  not a regression since there aren't any users of networkd + DNS early in
  boot at this time, it was requested that we move this DNS issue to a
  separate bug.
  
  [SRU]
  Fix: switch resolvconf.service to run Before=network-pre.target and add 
Wants=network-pre.target.  Add a Before=network-online.target to 
systemd-networkd-resolvconf-update.service to ensure we update /etc/resolv.conf 
with DNS config prior to reaching network-online.target.
  
  Regression potential: Low. networkd is not widely being used outside of
  netplan/snappy in xenial.

    lxc launch ubuntu-daily:xenial x1

This bug was fixed in the package resolvconf - 1.78ubuntu4

resolvconf (1.78ubuntu4) xenial; urgency=medium

  * debian/resolvconf.service: resolvconf service must run before any of the
possible network configuration services (ifupdown, networkd,
NetworkManager) so use network-pre.target instead of service names.

[Ryan Harper]

I've verified the SRU test with the package in Xenial proposed.  I've
also updated an UbuntuCore16 image with uses networkd and cloud-init to
validate that early networking which requires dns for resolving urls
works.

[Touch-packages] [Bug 1649931] Re: systemd-networkd needs to ensure DNS is up before network-online.target

[Ryan Harper]

systemd-networkd-resolvconf-update.service uses default dependencies
which will only run after sysinit.target, however cloud-init.service
needs to run before sysinit.target; systemd apparently dropped running
the service due to the inconsistent order.  Adding a
DefaultDependencies=no to systemd-networkd-resolvconf-
update.{service,path} allows cloud-init.service to run early with DNS
before sysinit.target.

I've marked verification failed for this bug since the current proposed
packages do not resolv the issue without changes to systemd package
(/lib/systemd/system/systemd-networkd-resolvconf-update.{service,path}.

[Touch-packages] [Bug 1649931] Re: systemd-networkd needs to ensure DNS is up before network-online.target

[Ryan Harper]

Something isn't working here.  I also typo'd the test-case, in
particular, the change to the cloud-init.service unit didn't specify
'systemd-networkd-wait-online.service', the sed command missed the 'd'
in networkd.

When I fix that, I find that systemd-networkd-resolvconf-update.service
does NOT run.  Manually adding that to
/lib/systemd/system/resolvconf.service.wants fixes the networkd boot
path, but of course breaks the ifupdown path.


** Description changed:

  Currently resolvconf and systemd-networkd don't ensure DNS has been
  configured before allowing network-online.target to be reached.
  
  This was discussed in https://launchpad.net/bugs/1636912 however it was
  not a regression since there aren't any users of networkd + DNS early in
  boot at this time, it was requested that we move this DNS issue to a
  separate bug.

  [SRU]
  Fix: switch resolvconf.service to run Before=network-pre.target and add 
Wants=network-pre.target.  Add a Before=network-online.target to 
systemd-networkd-resolvconf-update.service to ensure we update /etc/resolv.conf 
with DNS config prior to reaching network-online.target.
  
  Regression potential: Low. networkd is not widely being used outside of
  netplan/snappy in xenial.

[Robie Basak]

This has had systemd 231-9ubuntu3 stacked on top into xenial-proposed.
See bug 1647485 for details. When verifying, please test and verify
systemd 231-9ubuntu3, not the previous version, and confirm the package
version you tested in your comment to avoid any misunderstanding.
Thanks!

I accepted systemd into xenial-proposed but I received an LP timeout
when the script was trying to add a comment.  I image you can figure out
what to do from the resolvconf comment though.

  was not a regression since there aren't any users of networkd + DNS
  early in boot at this time, it was requested that we move this DNS

  [SRU]
  Fix: switch resolvconf.service to run Before=network-pre.target and add 
Wants=network-pre.target.  Add a Before=network-online.target to 
systemd-networkd-resolvconf-update.service to ensure we update /etc/resolv.conf

[Touch-packages] [Bug 1649931] Re: systemd-networkd needs to ensure DNS is up before network-online.target

Ok, it appears that post-16.04, systemd-networkd-resolvconf-
update.service is dropped from the package in favor of
debian/extra/units/systemd-resolved.service.d/resolvconf.conf, so this
patch does not apply.

I have verified that there is no ordering bug post-16.04, provided that
the changes to resolvconf are applied. /lib/systemd/system/systemd-
resolved.service.d/resolvconf.conf causes systemd-resolved to notify
resolvconf of its nameserver, if /run/resolvconf/enable-updates exists.
/run/resolvconf/enable-updates exists if resolvconf.service is started.
resolvconf.service is started Before=network-pre.target; network.target
is After=network-pre.target; systemd-resolved.service is
After=network.target.  So only the change to resolvconf is needed for
yakkety and beyond.

The point here is that 'regression potential' is not meant to be a scalar,
it's meant to be a description of where regressions are possible so that we
can assess whether additional testing is needed to guard against those
regressions.

And also to ensure that the SRU submitter has carefully thought about this
question, since going through that exercise usually results in a better SRU.

I'm not sure what you mean here; the systemd package in zesty is currently

  This was discussed in https://launchpad.net/bugs/1636912 however it
  was not a regression since there aren't any users of networkd + DNS
  early in boot at this time, it was requested that we move this DNS
  issue to a separate bug.

  
  [SRU]
  Fix: switch resolvconf.service to run Before=network-pre.target and add 
Wants=network-pre.target.  Add a Before=network-online.target to 
systemd-networkd-resolvconf-update.service to ensure we update /etc/resolv.conf 
with DNS config prior to reaching network-online.target.

  Regression potential: Low. networkd is not widely being used outside
  of netplan/snappy in xenial.

lxc launch ubuntu-daily:xenial x1

There is an upstream resolvconf bug that addresses that package portion:

I don't disagree (that saying few folks impacted means low).

This portion was split out from the previous systemd SRU

https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1636912

in which the changes were classified in the same way, so I was coping over
the assessment done by pitti and Foundations with which I agree.

I'd be happy if someone else could comment on whether they disagree with
the assessment.

IMO the risk is low:

The changes involve running resolvconf.service earlier (which sets an
inotify watch) and
does not regress anyone AFAICT.

Asking that DNS services (systemd-networkd-resolvconf-update.service) to
run before
network-online.target vs.  (how it is today) running after
network-online.target is reach
 also has low regression potential since _nothing_ requiring networking
should
run before systemd reaches network-online.target anyhow.

These potential users would already be broken since the units don't
currently
ensure that resolvconf (when  using networkd instead of
networking.service/ifupdown)
runs to completion before reaching network-online.target.

[Brian Murray]

How is this fixed in the development release?

Also the having a "Regression Potential" of low just because not a lot
of people use the service is wrong.  A bad change could still horribly
impact the users of the software, regardless of how many users there
are.

Title:
  systemd-networkd needs to ensure DNS is up before network-
  online.target

Status in resolvconf package in Ubuntu:
  New
Status in systemd package in Ubuntu:
  New

Bug description:
  Currently resolvconf and systemd-networkd don't ensure DNS has been
  configured before allowing network-online.target to be reached.

  This was discussed in https://launchpad.net/bugs/1636912 however it
  was not a regression since there aren't any users of networkd + DNS
  early in boot at this time, it was requested that we move this DNS
  issue to a separate bug.

  
  [SRU]
  Fix: switch resolvconf.service to run Before=network-pre.target and add 
Wants=network-pre.target.  Add a Before=network-online.target to 
systemd-networkd-resolvconf-update.service to ensure we update /etc/resolv.conf 
with DNS config prior to reaching network-online.target.

  Regression potential: Low. networkd is not widely being used outside
  of netplan/snappy in xenial.

  
  Test Case:
lxc launch ubuntu-daily:xenial x1
lxc exec x1 /bin/bash

# make sure you're on systemd-229-4ubuntu13
apt update && apt install -y systemd

# enable networkd and netplan
apt install -y nplan
  cat
