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.

Fixed In Version: rhel-system-roles-1.13.0-1.el9
Doc Type: Bug Fix
Doc Text:
.The Networking System Role no longer fails to set a DNS search domain if IPv6 is disabled Previously, the `nm_connection_verify()` function of the `libnm` library did not ignore the DNS search domain if the IPv6 protocol was disabled. As a consequence, when you used the Networking RHEL System Role and set `dns_search` together with `ipv6_disabled: true`, the System Role failed with the following error: ---- nm-connection-error-quark: ipv6.dns-search: this property is not allowed for 'method=ignore' (7) ---- With this update, the `nm_connection_verify()` function ignores the DNS search domain if IPv6 is disabled. As a consequence, you can use `dns_search` as expected, even if IPv6 is disabled.

Description Wen Liang 2021-09-16 11:49:55 UTC 
Description of problem:

When `dns_search` is specified and ipv6 method is ignore, when called with nm provider, the role relys on 
libnm function`nm_connection_verify()` to validate a configuration, as a result, libnm will emit the error message "nm-connection-error-quark: ipv6.dns-search: this property is not allowed for 'method=ignore' (7)". 
To properly handle this in the network role, the role should silently ignore such dns search setting for ipv6.
