Bug Description

[Impact]
Users need to write valid configuration, especially for new features that are approved by not yet implemented, such as marking a link "optional".

[Test case]
Write a netplan configuration:

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      optional: yes
      dhcp4: yes

And run 'netplan apply'. Netplan should write configuration for the link and not error out with a syntax error.

[Regression potential]
This has a minimal potential for regression: the new keyword was added to be supported already by consumers of netplan (users, cloud-init) so that they could start writing config with the new key and that configuration to be seen as valid by netplan before the backend is implemented. There is no functional change besides allowing for the value to exist in a netplan configuation.

---

If I define an interface in netplan (even one which has no DHCP type and no addresses), it's not possible to determine if its adminStatus should be enabled (link up) or disabled (link down).

I can completely exclude an interface from the netplan configuration, but I think that implies that not only its adminStatus is "disabled" by default, but also netplan will not be able to do anything "nice" for the interface, such as rename it to what the user specified in MAAS.

If I include the interface but don't specify any addresses or DHCP, it isn't clear if it will be link up (my current assumption) or link down.

There should be a way to allow an interface to be recognized by netplan (and even partially configured, waiting for the user to run something like 'ifup <interface>' on a manual but not auto-started interface in ifupdown), but marked administratively disabled. (adminStatus down)

summary: - No distinction between link-up and link-down unconfigured interfaces
+ No distinction between link-up and link-down interfaces

In ifupdown, 'manual' mode does accomplish this, yes. The side effect of this is that systemd does not block booting if the interface hasn't been enabled yet.

So the two relevant configuration knobs are:

(1) Should this interface be brought online at boot time? (default adminStatus)
(2) Should this interface be required to be up (and configured with an IP address) before the machine continues to boot? (lack of this requirement is implied by manual mode plus "auto <ifname>" in ifupdown)

We have seen MAAS bugs where these use cases have been problematic, such as users configuring a "backup bond" which is not (yet) online. (See also #1553617.)

That doesn't seem right; either you want/need the interface to dhcp
(mode=auto)
and then of course you block the boot waiting on DHCP and mark that it
failed
Or it's manual, in which case it;s not blocking boot as it won't be
required "up"
to continue.

I certainly agree that there's a need for dynamic configuration of
interfaces.
Networkd doesn't currently provide a complete solution here. And it
certainly
does not provide any link-state monitoring either; but we didn't have one
in
ifupdown either; collection of additional hooks/scripts/tools providing
this function not-with-standing.

I don't think it's clear that not blocking or blocking is the right or
expected
behavior; it's certainly possible that not getting an IP via DHCP might be
equivalent to not booting if that's the only ingress to the box remotely.

There's clearly a need for this feature, but I don't believe we want to
replicate
a collection of hooks/scripts to deliver this but rather examine what might
be
needed to deliver netlink monitoring/policy application as a first-class
feature.

I briefly looked at https://en.opensuse.org/Portal:Wicked which has a nanny
daemon listening to netlink and the network daemon to handle hotplug events
but can be extended to listen to link status and build actions based on
information.

Sounds to me like before we can implement something like this, we'd need a way to specify this to the renderer themselves. There will need bugs opened for NetworkManager and networkd to understand "administratively down" states -- ie. we configured this already but we want to keep the device down for now.

Also, as far as I know, systemd/networkd will follow their own rules, which likely currently enforce that interfaces defined as DHCP will attempt configuration even if there is no carrier. This should be tested carefully, and a bug opened if it's indeed an issue. We'll focus on just adminsitrative status for the bug report here.

This is a gray area but I want to say it impacts MAAS -- currently, we represent "link down" by leaving the interface out of the YAML. This is less than ideal.

If this gets fixed we will need to generate a cleaner Netplan YAML in MAAS.

I think this concern is based on an outdated concept of the boot process. Under systemd (which is the only init system for which netplan will be enabled), there is a distinction between 'network' and 'network-online' and only a small number of services will require 'network-online'. ssh is absolutely not one of them.

I think you're still describing a valid bug, in that it is likely useful to distinguish between required and optional interfaces for network-online. But the impact is much less than this.

Mike Pontillo (mpontillo) wrote :

This bug was observed with a backport of Netplan running on Xenial with systemd.

But if the systemd configuration files for each service will handle this by not blocking boot in the vast majority of cases, I'm happy with that, too.

Mike Pontillo (mpontillo) wrote :

What you describe will work for the majority of server and cloud use cases. But installing Ubuntu on a router (or L3 switch) will be problematic if nothing happens when links go up or down. Actions need to be taken, such as adding or removing routes, so that the kernel doesn't attempt to route traffic to link-down interfaces.

That is, with a standard ifupdown configuration, I observe that when an interface becomes link-down (assuming it is administratively up per ifupdown) the IP addresses remain configured, the local routes remain in place, and any routes via the interface remain in the kernel. Arguably this is incorrect behavior, and I don't know if networkd handles this in some different way. (If I remember correctly, it behaved similarly to ifupdown, but correct me if I'm wrong.)

Nor should you be! As I said, this is a valid bug.

Of course, but that is not a function of the netplan yaml declaration; it's
a function of the network config renderer. ifupdown has *no* policy daemon
for handling link-up/link-down events, therefore with ifupdown you don't get
any sensible handling. networkd and NetworkManager should both handle
link-down events correctly. If you find that networkd is *not* handling a
link-down event by removing the routes, please file a bug on systemd for
this and reference it here so we can prioritize resolving it.

The original bug report here that is relevant to netplan is not about
handling transitions between link-up/link-down state, it's about being able
to provide configuration for a network interface with the intent that either
a) this interface will not be automatically brought up, or b) this interface
will not be considered towards network-online status.

If you specifically observed that sshd was not running on a system that had
at least one up interface, that is not the designed behavior and I don't see
any way that this would be a result of a netplan or networkd bug. Please
report a bug on systemd if this is reproducible.

Just to clarify, it's not ever possible to /block/ boot with systemd. Even if all networking is required to complete a boot, but all of them fail, the system will come in "degraded" state. But as much as possible, will be configured.

What one can affect is boot ordering, and what is required to reach certain targets quicker. For example, it sounds like for the systemd-networkd-wait-online.service you may want to extend --ignore= argument with the interfaces that are "semi-managed". They are under networkd control, but one does not care about them during boot.

tags: added: id-59dd420cf831805e3c59b950

I think we're conflating two different issues here; marking a device as "optional" and not required for boot is different than specifying configuration for it, but expecting a backend to leave the interface down.

I'm adding "optional" as a valid config for now so we can start generating valid config, even if that won't be doing much until we have an implementation ready.

Steve Langasek (vorlon) wrote :

Agreed, these are two separate features, both of which we should support - though optional is the higher priority one, which has bubbled up elsewhere in addition, and having 'optional' is likely a usable workaround for Mike's use case.

I'll let him comment, but I don't think it is. 'optional' doesn't mean "please know about this config but also don't bring up the interface".

nplan 0.30 is in artful unapproved now, it adds the 'optional' key as something valid for config files.

nplan 0.32~16.04.2 fails to build because I mismerged 0.32 and broke the code skipping the test_routes_v6 test in the NetworkManager case. Therefore, it can't possibly pass SRU verification.

Verified nplan 0.32~17.10.3 for artful:
Verified nplan 0.32~16.04.4 for xenial:

nplan behaves as expected when the keyword "optional: yes" is set; device gets ignored by systemd-networkd-wait-online; which will report the correct status based on whether other devices are providing a connection.
