Hi!

The module I'm writing makes my computer crashes and I am now 
investigating the reasons. It seems to trigger an undesirable effect in 
some other parts of the netfilter code. Thus, I'd like to know if the 
following - that I'm doing - is possible: under certain conditions, my 
target module changes the conntrack information, for example it changes 
the tracked source address for another one.
Moreover, I sometimes generate packets using the hard_start_xmit 
function. Can packets generated in such a way go through any netfilter hook?

Thanks for any help,

         Emmanuel
