You can use nf_register_sockopt/nf_unregister_sockopt to do so. See Sect
4.6. Writing New modules -> Receiving Commands From Userspace in the
netfilter hacking how to. You can find an example in ip_tables.c.
If you don't like using getsocksopt/setsocksopt to pass information to
kernel space, you could also use netlinks sockets.

Pablo
