Hello,

I am writing a target for iptables.

My target has a table and I see that it is not working correctly on SMP
processor.

I want to know which modifications I must make, or where I can find an
example.

Thanks
Laurent

well, that's not enough info. Anyway, if all iptables rules are sharing
that table (I mean that table is defined inside the target as a global
var), I guess that you need reader/writer lock.

On the other hand, if the table is inside the target's private
information, that's different... you should have a look at ipt_limit.c
for a reference.

Robert Love has written a good article about this:

Check out also Rusty's unreliable guide for locking in the kernel.

Pablo

what is the exact problem?

Is it a problem with your target?

Or do you believe it's a problem with iptables?

wbr,
Lukas
