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.
Upstream recently received full among match support by making use of concatenated ranges support in nftables:
commit c33bae9c6c7a49c8af16df846e6112fc4727e643
Author: Phil Sutter <phil>
Date: Thu Feb 13 17:49:53 2020 +0100
ebtables: among: Support mixed MAC and MAC/IP entries
Powered by Stefano's support for concatenated ranges, a full among match
replacement can be implemented. The trick is to add MAC-only elements as
a concatenation of MAC and zero-length prefix, i.e. a range from
0.0.0.0 till 255.255.255.255.
Although not quite needed, detection of pure MAC-only matches is left in
place. For those, no implicit 'meta protocol' match is added (which is
required otherwise at least to keep nft output correct) and no concat
type is used for the set.
