Max ~40 firewall rules

[3hhh]

Qubes OS version:

4.0

Affected component(s):

qvm-firewall

Steps to reproduce the behavior:

Create a VM with more than ~40 firewall rules.

I directly edited firewall.xml and restarted the machine and/or qubesd for that.

Expected behavior:

VM starts.

Actual behavior:

VM doesn't start and some error about iptables is shown in journalctl.

If you do the same with ~30 rules, the VM starts.

General Notes:

Why is there a limit at all?

This is issue #1570, which was supposedly fixed, but apparently is not.
I however don't have the rights to reopen it.

There is compatibility layer to make templates/standalonevms imported from 3.2 working. And it fails there. Maybe this compat layer should be optional, opt-in? Or at least opt-out...

You can simply leave a comment on a closed issue indicating that it should be opened, and we'll reopen it.
