RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Germano Veit Michel 2023-05-11 02:52:40 UTC 
Description of problem:

Nodes randomly fail to configure this:

  desiredState:
    interfaces:
    - ipv4:
        enabled: false
      ipv6:
        enabled: false

      state: up
      type: vlan
      vlan:

            mode: trunk
            trunk-tags:
            - id-range:

      ipv6:
        enabled: false
      name: virt.toca
      state: up
      type: linux-bridge

With this error:

      INFO  nmstate::nm::query_apply::profile] Will retry activation 32 seconds\n[2023-05-11T01:29:22Z
      INFO  nmstate::nm::query_apply::profile] Reapplying connection 1aa8c24f-3334-4304-889e-2eee566cffb5:

      Bug: Manager(UnknownDevice): Failed to find a compatible device for this connection\n'"

On a system with this initial configuration:

[core@orange ~]$ nmcli c
NAME                UUID                                  TYPE           DEVICE

It seems to be unable to find enp4s0 (ethernet) to activate the connection.

Perhaps its trying to use enp4s (ovs-port)?

Rebooting and reprovisioning the node sometimes fixes it. 

Version-Release number of selected component (if applicable):
OpenShift 4.13-rc7
NMState operator 4.13.0-202304280215

NetworkManager-libnm-1.42.2-1.el9.x86_64
containernetworking-plugins-1.2.0-1.el9.x86_64
NetworkManager-1.42.2-1.el9.x86_64
NetworkManager-team-1.42.2-1.el9.x86_64
NetworkManager-tui-1.42.2-1.el9.x86_64
NetworkManager-cloud-setup-1.42.2-1.el9.x86_64
NetworkManager-ovs-1.42.2-1.el9.x86_64

I had no issues with this on RHEL 8.6 based OCP 4.12.

How reproducible:
20-30%

Steps to Reproduce:
1. Use a NNCP to create a vlan interface on the device used by OVNKubernetes 

apiVersion: nmstate.io/v1
kind: NodeNetworkConfigurationPolicy
metadata:
  name: virt-toca-orange
spec:
  desiredState:
    interfaces:
    - ipv4:
        enabled: false
      ipv6:
        enabled: false
      name: enp4s0.2
      state: up
      type: vlan
      vlan:
        base-iface: enp4s0
        id: 2
    - bridge:
        options:
          stp:
            enabled: false
        port:
        - name: enp4s0.2
      description: bridge for vlan 2
      ipv4:
        enabled: false
      ipv6:
        enabled: false
      name: virt.toca
      state: up
      type: linux-bridge
  nodeSelector:
    kubernetes.io/hostname: orange.toca.local


Actual results:
* Some nodes will fail, some will succeed, randomly. 

Expected results:
* All succeed, its the same configuration on all of them

Comment 5 Germano Veit Michel 2023-05-11 09:42:02 UTC 
It actually "activates" it just fine, the device is briefly present, enslaved to the bridge and UP, all set correctly:

30: virt.toca: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000
    link/ether 88:ae:dd:0e:b5:fc brd ff:ff:ff:ff:ff:ff
31: enp4s0.2@enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master virt.toca state UP mode DEFAULT group default qlen 1000
    link/ether 88:ae:dd:0e:b5:fc brd ff:ff:ff:ff:ff:ff

Then that error comes up, and it rolls back to the previous configuration, as if it failed. But AFAICS, it did set it up just fine.
Comment 6 Germano Veit Michel 2023-05-11 10:19:23 UTC 
If I restart NetworkManager and try the exact same thing again, then it works....
Comment 7 Gris Ge 2023-05-11 12:53:53 UTC 
Hi Garmano,

Can you collect trace level log of NetworkManager when you reproduced the problem?

 * sudo nmcli g logging level trace domains all
 * # Reproduce the problem
 * sudo journalctl  -u NetworkManager


After that, can you try to install nmstate scratch build in https://people.redhat.com/fge/bz_2202999/

Comment 9 Germano Veit Michel 2023-05-11 21:22:45 UTC 
The test build seems to work (tried 4 times, didn't reproduce - but this thing is temperamental).

Also, enabling NM debug as above seems to make it harder to reproduce, is this a race condition?

The issue happens here:

Germano, can you please attach the trace log of NM since it started, so that it is possible to check which other device is claiming the ifindex?

I think you are right, because with trace logs it gets considerably harder to reproduce.

Its harder to reproduce with tracing enabled.

Sequence of events for context:

1. Starting point was a successfully configured node (I fixed them all yesterday with NM restarts)
2. Enable NM tracing permanently
3. Delete the NNCP (configuration yaml in comment #0)
3. Reboot the node
4. SSH to the node and manually cleanup the devices (deleting the NNCP does not cleanup, IMHO thats another bug)
5. Reboot again
6. Create the NNCP
7. Hit the problem

logs_with_sucess_after_nm_restart.txt

Here is the entire logs.txt file again, but at the end of the file you will now see me restarting NM again and then retrying 2 times to delete the NNCP and add it again, it succeeds on the second attempt.

Maybe it helps, as you can compare a successful with an unsuccessful one from the same system and exact same config.
Comment 22 Beniamino Galvani 2023-05-22 09:23:15 UTC 
Okay, so the problem seems to be the following.

After the initial configuration done by MCO, there is a OVS bridge, and a connection "ovs-if-phys0" of type ovs-interface is active on enp4s0. There previous Ethernet connection named "Wired Connection 1" that refers to enp4s0 is still present but deactivated.

The nmstate YAML defines a Linux bridge with a "enp4s0.2" port of type VLAN which has parent enp4s0. nmstate creates a bridge connection and a VLAN connection that has "Wired Connection 1" as parent. The activation of the VLAN then fails because the current parent (ovs-if-phys0) is different from the UUID specified in the profile (Wired Connection 1).

This seems a bug in nmstate which is selecting the wrong (not active) connection as the parent for the VLAN.

It is also true that NM could be more helpful here and should just do what the user asks: activate the VLAN and if necessary also activate the parent (disconnecting the existing profile on the parent). However, this would be wrong in this scenario because the existing parent (the ovs-interface) must be preserved.

Thus, I think this must be fixed in nmstate; I'm reassigning the bugzilla.

What could be improved in NM is the logging:

 - there can be multiple ovs devices with the same name; in that case it's difficult to correlate log messages with the right device. To solve this, the log should also indicate the device type, at least for OVS devices.

 - it would be useful to log the reason why a connection is considered incompatible with a device. Since those messages scale with the number of connections times the number of devices, they are very verbose even at TRACE. We should consider using log domains to enable or disable them.

I will file a separate bugzilla for these improvements.

@fge please check the previous comment.
Comment 24 Gris Ge 2023-05-23 08:38:22 UTC 
Thanks for the hints!

Reproduced this problem locally:
 1. Use nmstate to create eth1 setting by:

```
---
interfaces:
  - name: eth1
    type: ethernet
    state: up
```

 2. Use nmcli to create another NM connection for eth1:

```
nmcli c add type ethernet ifname eth1 \
    connection.id 0eth1 ipv4.method disabled ipv6.method disabled
```

 3. Activate the newly created connection `nmcli c up 0eth1`

 4. Use nmstatectl to apply:

```yml
---
interfaces:
  - name: eth1.101
    type: vlan
    state: up
    vlan:
      base-iface: eth1
      id: 101
```

You have to try step 4 multiple times to trigger this issue.
