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.

In openshift we are attempting to configure some devices as unmanaged but this is not working as expected on all occasions.


We have this config /etc/NetwokrManager/conf.d/sdn.conf:

sh-4.4# sudo cat /etc/NetworkManager/conf.d/sdn.conf 
# ignore known SDN-managed devices
[device]
match-device=interface-name:br-int;interface-name:br-local;interface-name:br-nexthop;interface-name:ovn-k8s-*;interface-name:k8s-*;interface-name:tun0;interface-name:br0;interface-name:patch-br-*;interface-name:br-ext;interface-name:ext-vxlan;interface-name:ext;interface-name:int;interface-name:vxlan_sys_*;interface-name:genev_sys_*;driver:veth
managed=0


On an initial boot, it seems to work as expected:

That interface is not longer managed, as expected.

Comment 1 Beniamino Galvani 2022-04-26 08:11:56 UTC 
> patch-br-int-to-br-ex_ci-ln-vxc1wlb-72292-b2d6j-worker-a-r4gnj is managed when it shouldn't as per the configuration above.

I see, that's a bug.

Note that NM considers the device as "external" and so even it is marked as "activated", NM doesn't actually touch it:

  <info>  [1650644081.2483] device (patch-br-int-to-br-ex_ci-ln-vxc1wlb-72292-b2d6j-worker-a-r4gnj): state change: unmanaged -> activated (reason 'connection-assumed', sys-iface-state: 'external')

In other words, apart from the wrong state displayed ("activated" instead of "unmanaged"), NM is not actively managing the interface. Anyway, the wrong state is a bug that must be fixed.
Comment 2 Beniamino Galvani 2022-07-18 08:18:31 UTC 
To reproduce, I did:

  cat <<'EOF' > /etc/NetworkManager/conf.d/01-ovs-int0-unmanaged.conf
  [device-unmanaged]
  match-device=interface-name:ovs-int0
  managed=no
  EOF
  systemctl restart NetworkManager
  ovs-vsctl add-br ovs-br0
  ovs-vsctl add-port ovs-br0 ovs-int0 -- set interface ovs-int0 type=patch -- set interface ovs-int0 options:peer=ovs-br0

and saw in logs:

  <info>  [1658131864.0397] ovs: ovs interface "ovs-int0" ((null)) failed: No usable peer 'ovs-br0' exists in 'system' datapath.
  <info>  [1658131864.0398] device (ovs-int0): state change: unmanaged -> activated (reason 'connection-assumed', sys-iface-state: 'external')

Note the ovs-interface transitioning from "unmanaged" to
"activated". There are also some assertion failures a bit later:

  <info>  [1658131864.0404] device (ovs-int0): Activation: successful, device activated.
  _connection_get_setting_by_meta_type_check: assertion 'NM_IS_CONNECTION(connection)' failed
  _connection_get_setting_by_meta_type_check: assertion 'NM_IS_CONNECTION(connection)' failed
  _connection_get_setting_by_meta_type_check: assertion 'NM_IS_CONNECTION(connection)' failed

With the patch applied, the device stays in state unmanaged and the
assertions failures are gone.
