Description

Seeing multiple pfSense 23.01 users having these PHP fatal error crashes. I got it in the DHCP Server tab by simply clicking the "save" button.

Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /etc/inc/system.inc:422
Stack trace:
#0 /etc/inc/system.inc(520): system_hosts_dhcpd_entries()
#1 /etc/inc/system.inc(551): system_hosts_entries(Array)
#2 /etc/inc/services.inc(2772): system_hosts_generate()
#3 /usr/local/www/services_dhcp.php(788): services_unbound_configure()
#4 {main}
thrown in /etc/inc/system.inc on line 422

After that system is unresponsive with no connection. Rebooting via console works but while bootup more PHP errors (with the same "Cannot access offset of type string on string in" message) and the system fails to start. Only reverting config does help.

This issue happens with multiple clean installs on a Netgate 6100 MAX.

  • Status changed from New to In Progress

Looks like most (or all?) of these are from having an empty interface config in DHCP settings, e.g.

    <dhcpd>
        [...]
        <opt1></opt1>
    </dhcpd>

I'm working on fixes but in the meantime, editing those bad items out of the config would solve it locally.
