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.

Doc Type: Bug Fix
Doc Text:
When udev renamed a network interface and encountered a naming conflict, it renamed the interface to "[initial name]-[desired name]". Sometimes, this name was not unique and the naming conflict persisted. This bug has been fixed, udev now uses the unique interface index for renaming, and temporary names for interfaces are now of the following format: "rename[ifindex]".

Comment 2 Harald Hoyer 2011-06-17 13:06:14 UTC 
This prevents the occurrence of the temporary network interface names, when udev has to rename the network interfaces. Remember the "eth0-rename" or "eth0-eth1" temporary names?
Comment 3 Harald Hoyer 2011-06-17 13:07:11 UTC 
Ah, I should add the following: These temporary names were not "unique" enough, but using the IFINDEX should be.

    Technical note added. If any revisions are required, please edit the "Technical Notes" field
    accordingly. All revisions will be proofread by the Engineering Content Services team.

When udev renamed network interfaces and encountered a naming conflict, it renamed the interfaces to "<initial name>-<wanted name>". This name might also be not unique. So udev now uses the unique interface index for renaming and temporarily renamed interfaces now have the name "rename<ifindex>".
