Can you be a little more specific on what you have asked.
Is it that you want to know how to develop a new match??? Something like
a "state" or "conntrack" that has already been developed

Dear Anisha,
Sorry for being unspecific. I have implemented a match, this match is
called in the chains OUTPUT and INPUT. I would like to know a way of
accessing an structure or calling a function or something similar in
order to be able of doing a switch inside the match changing the
behaviour if the match is called from OUTPUT or INPUT.
Thank you very much
Regards
Antonio

You can't figure out the calling chain in a match: netfilter does not
provide the data. You have to pass the info as a command line option.
Best regards,

Thanks for the answers, I have not read ipt_state or contract but if
Jozsef is saying it is not possible I will provide the info through the
command line.
Thanks a lot to all

Dear Antonio,
No sorries please. I jus wanted to get more clear on your doubt.
Did you refer to the ipt_state or ipt_conntrack files for idea? They
involve number of structure and functional references. Is that what you
were looking for or am I taking you in a wrong direction?
