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 of problem:
Customer is requesting that BIND be upgraded to a newer version in RHEL7 so that they can take advantage of DNS enhancements relying upon it.


Version-Release number of selected component (if applicable):
9.9

How reproducible:
Always

Steps to Reproduce:
1. Try to run "delv"

Actual results:
Command not found


Expected results:
Command should run and return proper results when given proper arguments.


Additional info:

We have no delv command yet in RHEL 7, but there are some tools that could help with DNSSEC verification failures. Unlike delve, they do not have exactly the same algorithm of names verification as BIND. Most of common DNSSEC errors can be debugged with them easier than dig +sigchase.

- drill -S <domain> (from ldns package)
- unbound-host -vrD <domain> (from unbound package)

I think they are useful alternatives to missing delv, especially the first one.

Commit provided in rebase bug, just providing fixed-in version.

Note, upstream does not support dig +sigchase anymore, delv is recommended replacement. Failures in +sigchase mode are unsupported by upstream, sigchase support was removed in more recent versions altogether.
