enable and disable CoreXL instances on the fly

[HeikoAnkenbrand]

At R80.20 there's a new hack to turn the CoreXL instances on the fly on and off. Here is an example with 3 CoreXL instances!

Now start the command:

# fw ctl multik stop     -> stop CoreXL instance 1

# fw ctl multik stop    -> stop CoreXL instance 2

# fw ctl multik stop   -> The last instance cannot be disabled:-)

You can activate it again per:

# fw ctl multik start

Conclusion:
CoreXL 0 cannot really be deactivated under R80.10+:-)

To be honest I’m not sure what benefit this has.

[HeikoAnkenbrand]

There is nothing in the documentation about the cli command.

In the maintenance window I tested it on a bigger firewall. I could not see any negative impact.

That I only wonder, that the session counter will not be lower.

I just looked it over at the lab. The existing sessions are not affected.

Maybe someone from R&D can tell whether this has a negative impact or not.

I see here only the performance decrease if I disable CoreXL instances.
