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 Radek Novacek 2014-08-07 11:34:49 UTC

FirewallD D-Bus API currently provides two different sets of APIs, one for runtime configuration and one for permanent configuration.

Having two different sets of APIs for almost the same thing complicates the implementation of clients that will consume the API.

It would be great if FirewallD can provide same set of APIs for both runtime and permanent configuration, for example only D-Bus object path would differ or method argument would specify if we want to alter runtime or permanent configuration.

Comment 5 Thomas Woerner 2014-09-29 17:53:47 UTC

Fixed upstream: https://git.fedorahosted.org/cgit/firewalld.git/commit/?id=a15889cb6ffceecce8b2c9cafe71174b27a3864a

Comment 7 Radek Novacek 2014-10-07 08:04:59 UTC

Thanks, this is much better. I can imagine a code that would handle both runtime and permanent configuration.

However, those APIs are still a bit different. For example, adding port to the zone would look like this:

Runtime:
dbus.call("/org/fedoraproject/FirewallD1", "org.fedoraproject.FirewallD1.zone", "addPort", "public", "1234", "tcp", 0)

Permanent:
zone = dbus.call("/org/fedoraproject/FirewallD1/config", "org.fedoraproject.FirewallD1.config", "getZoneByName", "public")
dbus.call(zone, "org.fedoraproject.FirewallD1.zone", "addPort", "1234", "tcp")


So, I'm satisfied with using the current API, but unifying those two ways completely would be awesome.

Comment 8 Thomas Woerner 2014-10-07 11:29:03 UTC

I am sorry, but it is not possible to unify the runtime and permanent interfaces more than this within the Python version because of name conflicts in the server classes.

With the C++ recode version this will be possible, but it is not finished and available, yet.

Comment 9 Jiri Popelka 2014-10-14 16:42:47 UTC

Thomas, the following upstream commits should be included too:
