firewalld release

The new firewalld version is available as a security and bug fix release for version 0.4.3.

The main changes are

Fixes CVE-2016-5410

Any locally logged in user, could add and remove tracked passthrough rules and could set ipset entries. On top of this the policy to get zone, service, .. settings and also the log denied value is more strict now.

Standard error is now used for errors and warnings

Errors and warnings can now simply be skipped for example while getting the default zone with the command line client by piping stderr to /dev/null.

Several fixes for use in change roots

The command line use in change roots is not resulting in trace backs anymore. The client class, NetworkManager backend and also the command line clients have been adapted for this.

Systemd service file changes

The systemd service has been changed that firewalld gets started before the and before

Fixed translations in firewall-config

The translations in firewall-config hve not been correct at all times. The gettext textdomain was not set property which resulted in missing translations in the code.

Command line clients

Several error return code fixes have been added to fix the behavior with single and sequence options.

firewalld release

The new firewalld version is available as a bug fix only release for version 0.4.3.

The main changes are

Fix regression with unavailable optional commands

When a command is not available, new implementation to run a program raises an unexpected error which is not being handled by the callers. An emulation of the old behaviour has been added to fix this regression.

Revert to individual calls on missing restore commands

If iptables is available but not iptables-restore, then the transaction model was not able to apply firewall rules. With this change, individual calls will be used for missing restore commands. This applies to iptables, ip6tables and also ebtables.

Only ask for authentication once for add and remove options

With the use of the command backend a not authorized user was asked two times to authenticate for a query and later for the add or remove action that are done internally. With sequence options, the user was asked two times the number of options.

New RH-Satellite-6 service

The service has been included finally in the release. It does not need to be added in RHEL now.

The new firewalld version is available as a bug fix only release for version 0.4.3.

The main changes are

Fixes missing ICMP rules for some zones

The zone specific ICMP rules for ICMP block inversion have been missing in zones with bindings, that are defined in the zone configuration file.

Fixes issue with running programs using Python3

With using Python3 for firewalld, firewall rules have not been applied in some cases without an error message.

Splits up source and destination address lists for transaction

A direct rule could contain source and destination address lists. iptables splits them up to only contain one source and one destination address at maximum. This is also needed in firewalld especially with the transaction model that uses the restore commands.

Completed firewallctl and firewallctl man page

The firewallctl command line tool and also the man page of firewallctl have been completed.

There are also other bug fixes.

firewalld 0.4.3 release

The new firewalld version 0.4.3 is available with mostly bug fixes and some usability enhancements.

The main changes are

Add and remove several ipset entries with firewall-config

The graphical configuration tool firewall-config now also has the ability to add and remove ipset entries loaded from a file. This is the same as the the command line options –add-entries-from-file and –remove-entries-from-file. This is possible in the runtime and also to the permanent environment.

Create backup on removal of zones, services, ipsets and icmptypes

The configuration of a zone, service, ipset or icmptype is now preserved in a backup file on removal. The backup file has an additional “.old” extension. This makes it possible to manually undo removals.

Additional information zone handling with NetworkManager and ifcfg files

With version 0.4.2 the zone handling with NetworkManager and ifcfg files has ben changed to be more expected. Information about this hndling has been added to the firewalld and zone man pages.

Sequence options in all command line utilities

All command line utilities now support sequence options. It is now for example simply possible to add, remove and query several services in a zone.

New firewallctl command line utility

The new command line utility is an addition to the existing firewall-cmd and firewall-offline-cmd tools. It provides an other interface with shorter names.

Updated and new services

The high-availability service now also opens the port 5403/tcp for corosync-qnetd.

The new services are: kshell, rsh, ganglia-master and ganglia-client

Test suite enhancements

There are other bug fixes and also code clean ups.

firewalld 0.4.2 release

The new firewalld version 0.4.2 is available with enhancements, bug fixes and very nice speed ups.

The main changes are

New transaction model

Changes are done in one big transaction instead of smaller ones. This speeds up firewalld start and restart tremendously. The start is done up to in six or nine calls to the restore commands depending on the configuration. This depends on ipset and also direct configuration usage. Also all other actions benefit from this change.

Enhanced handling of connections and interfaces

For interfaces that are handled by NetworkManager, requests to add or change bindings are directed to NetworkManager in the firewall-cmd and firewall-config tools. For interfaces on Fedora and RHEL systems that are not handled by NM, there is a new mechanism that changes the ifcfg file if there is one using the interface. This makes zone interface bindings more consistent.

Usability enhancements for firewall-config

firewall-config has a new side bar with the active bindings of connections, interfaces and also sources. With this side bar it is possible to change the binding assignments in a simple way. A new overlay message window if the connection to firewalld could not be established or if it is lost. Speed ups for view changes runtime to permanent and back by introduction of new D-Bus methods in firewalld. The resize behavior has been fixed to be more expected.

Enhanced runtime to permanent migration

The enhanced migration is not saving interfaces that are under control of NetworkManager to the permanent configuration. Zones, services etc. are only migrated if there are changes compared to current permanent configuration.

New ICMP block inversion

The ICMP block is now completely handled per zone. With the new ICMP block inversion flag in the zone it is possible to invert the ICMP block. That means that the enabeld ICMP blocks are allowed and all others are blocked. In a drop zone these remaining types are dropped and not blocked. The logging of denied rules have been added to icmp-blocks.

Source port support in zones, services and rich rules

Additionally to ports is it also now possible to allow source ports in a zones and also in a service in a similar way as existing ports. There is a new flag source-port for this. Source ports can also be used in rich rules as elements. The source ports can be combined with logging, limiting and also an action.

Rich rules with destination only

Destination addresses can now be used in rich rules without an element. This enabled the use of rich rules containing destination addresses combined with an action and logging only.

There are also several other bug fixes or enhancements and code optimizations.
