Very urgent: looking up a flow in the kernel structures given its identifier

Hello,
I am looking for a function which, supplied whith the
tuple identifier (ip_src,ip_dst,p_src,p_dst), returns
the corresponding skb.

Does this function exist?
Regards,

Siri.

Look at tcp_v4_rcv -> __inet_lookup, dccp_v4_rcv -> __inet_lookup,
ditto for SCTP, UDP.
