Hello everybody,

we wrote a kernelspace module which uses the now deprecated
ip_conntrack API and we are trying to switch to the new nf_conntrack
but this seems to be a little bit more problematic than we thought
first.
What we want is to build a nf_conntrack_tuple to get the hash for an
existing connection and finally the id of the connection.
Everything worked fine with the old ip_conntrack stuff but now we don't
get any matching tuples any more.
We also managed to find out that /proc/net/nf_conntrack only has
entries when we load nf_conntrack_ipv4 before, but even if we load it,
the problem is not solved by that.
Maybe someone can help us with this, I will attach the code of our
module for better clarification.

thanks and best regards,
Thomas
