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 Jirka Klimes 2014-03-07 09:53:25 UTC 
NetworkManager should allow taking over configurations where device has only a link-local IPv6 address and existing ifcfg configuration file has 'ignore' IPv6 method.

Comment 6 Dan Williams 2014-03-11 16:53:18 UTC 
Branch looks good, but could you add a testcase?  There are already some in src/tests/test-general.c.
Comment 7 Georg Markgraf 2014-03-12 07:17:44 UTC 
Because RHBZ 1073385 is "urgend" and is marked DUP to this BZ, I adapt severity of this RHBZ (1073824) also to urgend.
I cannot adapt Priority -> please take of that when DUPing BZs to ensure the prioritization of BZs remain adaquate

A testcase has been added and the code pushed to upstream master as:
4112bda core: allow matching IPv6 'link-local' method to 'ignore' (rh #1073824)
Comment 10 Ladislav Jozsa 2014-03-17 17:28:38 UTC 
Verified with NetworkManager-0.9.9.1-3.git20140313.el7 on RHEL-7.0-20140317.0. When ipv6 method contains ignore keyword, the connection is taken over by Network Manager and new connection isn't created.

Moving to verified.
Comment 11 Ladislav Jozsa 2014-03-17 22:26:34 UTC 
Vladimir, may I ask why did you moved the bug back to ON_QA state?
Comment 12 Vladimir Benes 2014-03-17 22:28:49 UTC 
Ladislav, please do use just comments if you want to state that fix works. We need to do some additional work on these bugs but moving to VERIFIED may confuse our radars ;-)

Test covered by automated case and manual version as well. Test job verifying the fix here:

Still present in snap 11
Comment 14 Radek Vykydal 2014-04-01 14:26:51 UTC 
*** Bug 1073385 has been marked as a duplicate of this bug. ***
Comment 15 Jan Stodola 2014-04-01 14:56:47 UTC 
As comment 13 says, this issue is still reproducible with Snapshot 11 (which contains NetworkManager-0.9.9.1-3.git20140313.el7), when using static IPv4 configuration.
Since bug 1073385 has been marked as a duplicate of this one and the issue from bug 1073385 is still reproducible (even with Snap 13), moving this bug back to ASSIGNED.
Comment 17 Jirka Klimes 2014-04-01 15:56:22 UTC 
This is definitely another bug. See in the logs that ipv6.method is 'ignore' for both connections.

What might be an issue here is S390 stuff or mac-address. Either NM connection matching should be enhanced with this regard, or maybe dracut-generated ifcfg-file is not right.

I'm moving this bug back to VERIFIED and will clone it for the issue in comment #13.

Also when testing would you people use latest snaphots/NM, else we might be chasing already fixed bugs, and it lowers our resource capacity.
Comment 18 Jirka Klimes 2014-04-01 15:57:09 UTC 
I don't have rights to move it to VERIFIED. Please do that for me.

The issue in comment #17 cloned as bug 1083196.

Jirka,
thanks for the new bug, connection details have been attached there.
I'm also moving this bug back to VERIFIED.
