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 2023-03-13 04:18:01 UTC 
Description of problem:
It's very similar with https://bugzilla.redhat.com/show_bug.cgi?id=2154339 , but seems the current reproducer requires more steps.

Version-Release number of selected component (if applicable):
nmstate-2.2.7-1.el9.x86_64
nispor-1.2.10-1.el9.x86_64
NetworkManager-1.42.2-1.el9.x86_64
DISTRO=RHEL-9.2.0-20230307.10

How reproducible:
100%

Steps to Reproduce:
ip netns add client
ip netns add server
ip link add veth0_c type veth peer name veth0_c_p
ip link add veth0_s type veth peer name veth0_s_p
ip link set veth0_c_p netns client
ip link set veth0_s_p netns server
ip netns exec client ip link set lo up
ip netns exec client ip link set veth0_c_p up
ip netns exec client ip addr add 192.168.0.1/24 dev veth0_c_p
ip netns exec client ip addr add 2000::1/64 dev veth0_c_p
ip netns exec server ip  link set lo up
ip netns exec server ip  link set veth0_s_p up
ip netns exec server ip addr add 192.168.0.2/24 dev veth0_s_p
ip netns exec server ip -6 addr add 2000::2/64 dev veth0_s_p
nmcli device set veth0_c managed yes
nmcli device set veth0_s managed yes
