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:
Today curl upstream announced that they are going to completely remove support for metalink from curl already in the next release of curl due to a number of difficult to fix security issues:

    https://curl.se/mail/archive-2021-06/0006.html
    https://github.com/curl/curl/pull/7176

I believe it is not too late to follow this decision in RHEL-9, too.  We could hardly support it ourselves till RHEL-9 EOL when it is broken and unsupported upstream since the beginning.


Version-Release number of selected component (if applicable):
curl-7.76.1-4.el9


Steps to Reproduce:
1. curl -V | grep -i metalink


Additional info:
We might want to do the same with wget and consider removing libmetalink, which seems to be dead upstream:

    https://launchpad.net/libmetalink

I will file separate bugs for wget and libmetalink for consideration.
