firewall: Ensure the xt_geoip module is always loaded

  For some reason, this module is not present after the very first boot of
an IPFire installation.

Fixes: #12767

Hello,

I would be great to know *why* this is happening.

iptables should automatically trigger loading the kernel module.

Did we just forget to run something like depmod -a?

Hello Michael,

thanks for your reply.

I have no idea, but am interested in the root cause of this as well. It only happens
while loading the firewall engine on first boot. On every subsequent boot, iptables
does not complain.

Thanks, and best regards,
Peter Müller

Hello,

So what would be different upon first boot?

We will probably run a location update after the first time we connect to the internet and refresh the database, because the one that was shipped is likely too old.

However, I checked the code of the xt_geoip module and it does not look like it would complain in any way that it would look like the module does not exist - so the kernel simply cannot find it.

That only leaves us with a missing module on the dependency tree (but we would never update that in production I believe) or that the file can simply not be opened.

strace might help with this.
