firewalld 0.4.4.2 release
The new firewalld version 0.4.4.2 is available as a second bug fix release for 0.4.4.
The main changes are
Lazy NMClient creation
The NMClient creation is now delayed till it is really used. With firewalld version 0.4.4 it has been created at import time of the fw_nm module, which could result in a start issue with NetworkManager.
Use configure for kmod utils path detection
The kmod utils are not placed in the paths for all distributions. The tools and their path is now detected within the configure call.
Enhancements and fixes for the ifcfg io backend
The ifcfg io file backend is now properly hadnling quoted values and is not failing on shell script code in the ifcfg file.
Do not reset ZONE with ifdown and enabled network service
On reboot or shutdown the zone has been reset to default in an ifcfg file if the network service was enabled and controlling the interface.
The call of firewall-cmd --remove-interface
in ifdown.post
is now only removing the zone binding in the firewall, but not modifying the ifcfg file anymore.

firewalld 0.4.4 release
The new firewalld version 0.4.4 is available as an enhancement and bug fix release.
The main changes are
Support Recognition of Automatic Helper Assignment Setting
Automatic helper assignment has been disabled in kernel 4.7. firewalld version 0.4.4 is now able to recognize this and to create rules if automatic helper assignment has been turned off to make conntrack helpers work again. If automatic helper assignment is turned on, then firewalld will behave as before.
For more information about the use of netfilter conntrack helper, please have a look at Automatic Helper Assignment
Firewall-applet is now using Qt5
The firewall applet has been ported from Qt4 to Qt5.
Fixes LogDenied for zone reject targets
The logging rules for LogDenied have been placed after the reject rules for zones using the reject targets. The logging rules are now placed before these reject rules to fix logging.
Does not abort transaction on failed ipv6_rpfilter rules
The existing transaction will be executed before trying to add the rules for ipv6_rpfilter and a new transaction will be used to apply the ipv6_rpfiler rules. If this transaction fails, a warning is printed out and the remaining rules are applied with the next transaction.
Enhancements for the command line tools
The command line tools are now more consistent with errors and error codes in sequence options. The NOT_AUTHORIZED error is now also working.
New services
The services cfengine, condor-collector and smtp-submission have been added.
Several other enhancements and fixes

Automatic Helper Assignment
With kernel 4.7 and up the automatic helper assignment in kernel has been turned off by default. Netfilter conntrack helpers like for example nf_conntrack_ftp now need to be used in a different way. See Secure use of iptables and connection tracking helpers for more information.
The new AutomaticHelpers configuration setting has been added to firewalld.conf:
# AutomaticHelpers # For the secure use of iptables and connection tracking helpers it is # recommended to turn AutomaticHelpers off. But this might have side effects on # other services using the netfilter helpers as the sysctl setting in # /proc/sys/net/netfilter/nf_conntrack_helper will be changed. # With the system setting, the default value set in the kernel or with sysctl # will be used. Possible values are: yes, no and system. # Default: system AutomaticHelpers=system
firewalld is now checking the /proc/sys/net/netfilter/nf_conntrack_helper
kernel setting at start. With AutomaticHelpers set to system, this is the default, firewalld will use the actual setting in the kernel. This could wither be the default in the kernel itself or has been set using sysctl.
If automatic helper assignment is turned off, firewalld will create rules in the PREROUTING chain of the raw table to enable the helper for the zone, where it is used. For this it uses the helper settings defined in the new helpers. These are the nf_conntrack_ module that provides the helper, the optional family if a helper could only be used for IPv4 or IPv6 and also the ports. The helper will only listen on the ports defined in the helper configuration. If there is a need to modify these ports,
then it is possible to create an adapted configruaiton either with the GUI or command line tools or by copying the file to /etc/firewalld/helpers
. If you want to change the protocol, please make sure that the helper is able to use this protocol. There is only a limited amount of helpers that are abel to handle more than one protocol.
Here is an eample of the ftp helper added by enabling the ftp service in the public zone:
# iptables -t raw -S | grep CT -A PRE_public_allow -p tcp -m tcp --dport 21 -j CT --helper ftp
A new backend has been added, the D-Bus interface has been extended, also the GUI and command line tools and the documentation.
firewalld 0.4.3.3 release
The new firewalld version 0.4.3.3 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 network-pre.target and before multi-user.target.
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.
