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.
* Previously, the corosync utility failed to start when the DNS returned IPv6 addresses, corosync was configured to use hostnames instead of IP addresses, and corosync was configured to use IPv4. With this update, the corosync parser can resolve the hostname regardless of the IP address type returned and the corosync configuration. As a result, corosync starts in the described circumstances as expected. (BZ#1333396)

totemconfig: Explicitly pass IP version
If resolver was set to prefer IPv6 (almost always) and interface section
was not defined (almost all config files created by pcs), IP version was
set to mcast_addr.family. Because mcast_addr.family was unset (reset to
zero), IPv6 address was returned causing failure in totemsrp.
Solution is to pass correct IP version stored in
totem_config->ip_version.
Patch also simplifies get_cluster_mcast_addr. It was using mix of
explicitly passed IP version and bindnet IP version.
Also return value of get_cluster_mcast_addr is now properly checked.
