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 Vladimir Benes 2022-01-20 17:02:46 UTC 
Description of problem:
when running the test two times it doesn't behave deterministically. It fails for the second time and passes again when you leave the machine for let's say 10 minutes.

https://jenkins-networkmanager.apps.ocp.ci.centos.org/job/NetworkManager-main/878/artifact/FAIL-report_NetworkManager-ci-M1_Test0128_ipv6_routes_with_src.html

  Scenario: nmcli - ipv6 - routes - set route with src
    * Add a new connection of type "ethernet" and options "ifname eth3 con-name con_ipv6 autoconnect no ipv6.method manual ipv6.addresses 2000::2/126 ipv6.route-metric 256 ipv6.routes '2806:aabb:abba:abab:baba:bbaa:baab:bbbb/128 src=2000::2'" ... passed in 0.033s
    * Bring "up" connection "con_ipv6" ... passed in 0.056s
    Then "2806:aabb:abba:abab:baba:bbaa:baab:bbbb dev eth3 proto static src 2000::2 metric 256" is visible with command "ip -6 route" in "5" seconds ... failed in 5.016s

Steps to Reproduce:
1. ./test_run.sh ipv6_routes_with_src
Comment 1 Filip Pokryvka 2022-01-24 11:46:09 UTC 
This is wrongly assigned to rhel8, there the test passes in loop.

The problem is on rhel9/centos9stream. The first test PASS, next in the loop are FAIL. It seems to be eth3 gets into inconsistent state (which even some ipv6 test before can cause, so we see it failing), so the test fails on the next run. Maybe it is related to newer kernel.

Using fresh veth pair works, this should be reverted to cover this bug:

Comment 5 Vladimir Benes 2022-02-22 12:27:11 UTC 
It looks the issue is fixed a bit earlier than in NetworkManager-1.36.0-0.10.el9 but definitely reproducible with NetworkManager-1.36.0-0.4.el9 and not with the latest one.
