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.
The untruncated error message is:
usage: see firewall-cmd man page
firewall-cmd: error: ambiguous option: --delete could match --delete-icmptype, --delete-service, --delete-zone
It seems that the --delete option for iptables via --direct --passthrough no longer works.
This worked fine with firewalld-0.3.9-3.el7

BTW, also no any documents about --delete-{zone|icmptype|service} options in the firewall-cmd man page.

Description of problem: The new /usr/bin/firewall-cmd cmdline hasn't a '--delete' option for deleting firewall rules, however, the iptablesCommandNew() only sets 'action' as "--insert" or "--delete" in src/util/viriptables.c. Version-Release number of selected component (if applicable): # rpm -q libvirt firewalld kernel libvirt-1.1.1-25.el7.x86_64 firewalld-0.3.9-6.el7.noarch kernel-3.10.0-86.el7.x86_64 How reproducible: always Steps to Reproduce: 1. # tail -2 /etc/libvirt/libvirtd.conf log_outputs="1:file:/tmp/libvirtd.log" log_filters="3:remote 4:event 1:libvirt 1:conf" 2. # service libvirtd restart 3. # grep firewall-cmd /tmp/libvirtd.log | head -1 Actual results: # grep firewall-cmd /tmp/libvirtd.log | head -1 2014-02-27 10:57:45.070+0000: 12036: error : virCommandWait:2399 : internal error: Child process (/usr/bin/firewall-cmd --direct --passthrough ipv4 --table nat --delete POSTROUTING --source 192.168.122.0/24 -p tcp '!' --destination 192.168.122.0/24 --jump MASQUERADE --to-ports 1024-65535) unexpected exit status 2: usage: see firewall-cmd man page Expected results: Fix it.
