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 Mingyu Shi 2022-06-08 02:56:47 UTC 
Description of problem:
This is a consequent regression of https://bugzilla.redhat.com/show_bug.cgi?id=1861668 , but happened in env cleaning phase(remove the interfaces)

Version-Release number of selected component (if applicable):
nmstate-2.1.1-0.alpha.20220602.5accbd1.el9.x86_64
NetworkManager-1.39.5-1.el9.x86_64
DISTRO=RHEL-9.1.0-20220606.1

How reproducible:
100%

Steps to Reproduce:
ip link add veth0 type veth peer name veth0_ep
ip link set veth0 up
ip link set veth0_ep up
nmcli device set veth0 managed yes
nmcli device set veth0_ep managed yes

ip tuntap add name tap0 mode tap
ip link add br0 type bridge
ip link set tap0 master br0
ip link set tap0 up
ip link set br0 up

cat << EOF > target.yaml
---
interfaces:
  - name: br0
    type: linux-bridge
    state: up
    bridge:
      port:
        - name: veth0
EOF

nmstatectl apply target.yaml

echo "
interfaces:
  - name: br0
    type: linux-bridge
    state: absent
  - name: veth0
    type: ethernet
    state: absent
" | nmstatectl apply

Expected results:
No failure

Additional info:
In this case, nmstate-rust is able to recognize "type: Tun", but even removing br0 and tap0 in one transaction failed too.
Comment 1 Gris Ge 2022-07-20 09:24:01 UTC 
Hi Mingyu,

We don't support TUN interface, hence it is reasonable to fail the deletion of this bridge when it has unmanaged interface attached.

Can you check what does nmstate did on RHEL 8.6 ?
Comment 2 Gris Ge 2022-11-17 14:04:10 UTC 
Issue fixed on nmstate-2.2.1-1.el9
