So, I've got my code in userland (using netfilter_queue) that tries to
handle packets according to different attributes (sort of a firewall).
Is it possible to get the pid of sender program?
I'm aware that it is possible to apply pid-based rules with iptables
directly, but how could I access that property in the NFQUEUE?
Thanks,

You can't for now. Patches to access to UID GID have been made available
recently:

I don't think it should be too complex to propose the same for PID.
