pfSense » pfSense Packages

When pfblocker is not enabled or there is nothing setup for pfblocker to do, and there are no other aliases defined in the pfSense alias table, pfblocker.inc sync_package_pfblocker logs a PHP error when trying to process the empty alias table. The "if" test at:

#update pfsense alias table
if (is_array($config['aliases']['alias'])){
$aliases=$config['aliases']['alias'];
foreach($aliases as $cbalias){
...
}
}

needs to be a block that covers both statements above, as shown.
In the existing code the if test only applies itself to the 1 line immediately following it.
Otherwise the "foreach" line logs an error because $aliases is null.
This case applies equally to 2.0.n and 2.1
A sample corrected file is attached.
