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 of problem:

When moving linux bridge port with VLAN filtering to bond, got failure:

A connection with a 'bridge-port' setting must have the port-type
set to 'bridge'. Instead it is 'bond'


The same problem also exist for moving system port from OVS bridge to bond.

Version-Release number of selected component (if applicable):
nmstate-2.1.4-1.el9

How reproducible:
100%

Steps to Reproduce:
1. Apply these two yaml files via nmstatectl sequentially.

2. 
---
interfaces:
- name: br0
  type: linux-bridge
  state: up
  bridge:
    port:
      - name: eth1
        vlan:
          mode: access
          trunk-tags: []
          tag: 305

3. 

---
interfaces:
- name: br0
  type: linux-bridge
  state: up
  bridge:
    port: []
- name: bond0
  type: bond
  state: up
  link-aggregation:
    mode: balance-rr
    port:
    - eth1

Actual results:

Failure

Expected results:

No failure. Bridge port move to bond.

Additional info:

This is only reproducible on linux bridge when port has VLAN filtering.
For OVS bridge, it is always reproducable when moving OVS system port to bond.

Patch posted to upstream: https://github.com/nmstate/nmstate/pull/2016


Both linux bridge and OVS bridge should works as expected.

Many thanks to Eitan Raviv who report this issue to us.

Can it be backported to 9.1, so oVirt users can consume it also as a part of stable RHEL/Rocky/Alma release?

Hi Martin Perina,

Sure. Let me prepare the backport scratch build for testing and zstream review.

Verified with:
nmstate-2.2.1-1.el9.x86_64
NetworkManager-1.41.4-2.el9.x86_64
openvswitch2.15-2.15.0-75.el9fdp.x86_64
Linux dell-per740-80.rhts.eng.pek2.redhat.com 5.14.0-197.el9.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Nov 16 14:31:27 EST 2022 x86_64 x86_64 x86_64 GNU/Linux
