- Update to 4.4.22.3. Corrections in this release are below.
* On older distributions where 'shorewall show capabilities'
indicates 'Connection Tracking Match: Not Available', harmless
Perl diagnostics like the following could be issued:
Use of uninitialized value $list in pattern match (m//)
at /usr/share/shorewall/Shorewall/Config.pm line 1273,
<$currentfile> line 14.
Use of uninitialized value $list in split
at /usr/share/shorewall/Shorewall/Config.pm line 1275,
<$currentfile> line 14.
* On older distributions where 'shorewall show capabilities'
indicates 'Mangle FORWARD Chain: Not Available', entries in the
ecn file generated the following Perl Diagnostic:
Use of uninitialized value in hash element
at /usr/share/shorewall/Shorewall/Chains.pm line 1119.

* Previously, if a provider interface was derived from an optional
wildcard entry in /etc/shorewall/providers, then the interface
was never considered to be usable.
Example:
/etc/shorewall/interfaces:
#ZONE INTERFACE BROADCAST OPTIONS
net ppp+ - optionsl
/etc/shorewall/providers:net
#PROVIDER NUMBER MARK INTERFACE ...
ISP1 1 1 ppp0
* When 'shorewall update' or 'shorewall6 update' results in no change
to the .conf file, a message is issued, the .bak file is removed
and the command terminates without error.
