pfSense

Applied in changeset 67807c9536ae1810a067155049c96e8d2b634777.

Was able to replicate this after verifying <filter></filter> in config, connecting on the Anti-lockout rule, and trying to add a new firewall rule on LAN I received this error when the GUI failed:

Fatal error: Uncaught Error: Only variables can be passed by reference in /etc/inc/pfsense-utils.inc:2864 Stack trace: #0 /usr/local/www/firewall_rules_edit.php(146): filter_rules_sort() #1 {main} thrown in /etc/inc/pfsense-utils.inc on line 2864 PHP ERROR: Type: 1, File: /etc/inc/pfsense-utils.inc, Line: 2864, Message: Uncaught Error: Only variables can be passed by reference in /etc/inc/pfsense-utils.inc:2864 Stack trace: #0 /usr/local/www/firewall_rules_edit.php(146): filter_rules_sort() #1 {main} thrown

After hitting the Back button in the browser I had an alert:

Upgraded to Current Base System 2.4.5.a.20181120.0855, retested with same steps, was able to add new firewall rule without issue.

Confirmed resolved.
