Hi,
I have a working kernel dev setup with KGDB/KDB. Now as i'm going to
develop a netfilte module, i need a good strategy to debug netfilter
modules. During configuring the kernel i've bumped into a kernel config
like following :
CONFIG_NETFILTER_DEBUG
But i've found no documentaion describing what actually this
configuration will enable me to do.
So anything regarding this config variable or any other general
debugging strategy will be helpfull.
Cheers.

With this, the kernel will print debugging information on what the
Netfilter core infrastructure is doing. It also includes some
debugging messages from x_tables instances, ie. ebtables, arp_tables,
and so on.
It's been ages since I haven't used this for any useful purpose
(rather than making sure the kernel compilation does not break with it
enabled).
