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.

Looking at the original bug (1685804) I see that two of the 4 patches
can be omitted, it was never confirmed one actually improved the host
name lookup while the other is purely an improvement in the text of
the error message issued on host name lookup failure.

However, one of the two remaining patches is fairly large so it might
not be ok for z-stream.

OTOH the risk is low since the change is already included in RHEL-7.7
and there aren't many users of the amd format map support.

For my part I think the change is sound, is low risk, and recommend
going ahead with the z-stream update.

On Aug 6, 2020 Red Hat Enterprise Linux 7 entered Maintenance Support 2 Phase.

https://access.redhat.com/support/policy/updates/errata#Maintenance_Support_2_Phase

That means only "Critical and Important Security errata advisories (RHSAs) and Urgent Priority Bug Fix errata advisories (RHBAs) may be released". This BZ does not appear to meet Maintenance Support 2 Phase criteria so is being closed WONTFIX. If this is critical for your environment please open a case in the Red Hat Customer Portal, https://access.redhat.com ,provide a thorough business justification and ask that the BZ be re-opened for consideration in a future erratum.
