Zenarmor won't start after 22.7.5 update

[deckard26354]

After updating to OPNsense 22.7.5 zenarmor is refusing to start the packet engine service.

I receive the following dialog after trying to start it manually:

Code: [Select]

Warning: zenarmor is stopped because of a problem

zenarmor has detected a problem during operation and has shut down zenarmor services in order to prevent a network outage.

It is highly probable that this is due to a netmap issue where netmap might not be inter-operable with your current ethernet adapter.

If you think this is something we should have a look, just click here to let us know about the details and we will investigate this further.

You can re-enable the services from Status page.

I also receive an email notification with the following:

Code: [Select]

I've reported this to Sunnyvalley also.

It looks like the issue was due to local config.  I had an interface marked as 'protected' in zenarmor that was currently unused in opnsense (it was to be my tagged vlan interface).  Following the update the interface vanished from the zenarmor interface list but was still present in the configuration.  Re-saving the zenarmor configuration removed the interface from the config and allowed zenarmor to start properly.
