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.

firewall-cmd --reload output after adding hash:net,net ipset

Description of problem:
Adding an ipset of type "hash:net,net" (using `firewall-cmd --permanent --new-ipset`) reports success, but subsequent `firewall-cmd --reload` fails and firewall-cmd continues to exhibit strange behavior.

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

How reproducible:

Steps to Reproduce:
# systemctl start firewalld
# firewall-cmd --permanent --new-ipset testset --type hash:net,net
# firewall-cmd --reload

Actual results:
Error: COMMAND_FAILED: 'python-nftables' failed: internal:0:0-0: Error: No such file or directory

NB: Afterwards, `firewall-cmd --state` reports "not running" despite some commands working as expected (e.g. firewall-cmd --version) and systemctl reporting the firewalld service status as "active (running)". Only after restarting the service using systemctl does `firewall-cmd --state` report "failed" and the following line appears in the journal:

ERROR: COMMAND_FAILED: INVALID_TYPE: ipset type name 'hash:net,net' is not valid

Expected results:

Additional info:
Full command output attached.
