Hello, I want to add few fields to conntrack. They are specific to a flow. So, it doesn't make sense adding them to nf_conntrack_tuple. I can add them to nf_conn struct similar to mark and secmark fields. Or, I can add them to nf_ct_ext. I am guessing nf_conn_counter uses it. What do you folks recommend? Will be there be any performance issues other than the extra memory requirement? Thanks.
