About a patch to unclean module.

About a patch to unclean module.

[Maciej Soltysiak]

Hello,

I may say now, that I have finished writing the module, updating the
lipipt_unclean.c, I have created the patches to the netfilter tree.

But, suppose, Harald applies the patch. It will change libipt_unclean.c
in a way, that withougt running patch-o-matic it will not compile, because
it uses an include file
KERNEL_DIR/include/linux/netfilter_ipv4/ipt_unclean.h which will be only
available after patching the kernel tree.

So how do we solve that?
I see it by adding ipt_unclean.h to the netfilter tree.

Or maybe I am missing something or forgetting about something, some simple
solution.


Regards,
Maciej Soltysiak

The easiest way is to use the userspace patching facility of patch-o-matic.
Just look at extra/ipt_REJECT-fake-source.patch and especially
extra/ipt_REJECT-fake-source.patch.userspace for an example of userspace
patching.

GNAH!  As soon as somebody is using this evil confusing hack without it
being absolutely necessarry, I'll start flaming him.

See my other mail in this thread.

this is a comon problem, and it's always solved the same way: Put the
kernel include file into userspace/include/linux/netfilter_ipv4/.
