I am using/compiling against kernel version 3.3. With v3.2 that doesn't happen. Am I missing something?

This is resolved in the now-new xtables-addons 1.42.

When I try to link/build xtables-addons 1.42 against kernel 3.3.1 I get this:

WARNING: /lib/modules/3.3.1-3.fc13.i686/extra/xtables-addons/xt_ECHO.ko needs unknown symbol ip6_dst_hoplimit
WARNING: /lib/modules/3.3.1-3.fc13.i686/extra/xtables-addons/xt_ECHO.ko needs unknown symbol ip6_local_out
WARNING: /lib/modules/3.3.1-3.fc13.i686/extra/xtables-addons/xt_ECHO.ko needs unknown symbol ip6_route_output

I do not have ipv6 enabled at all, maybe that's why this is happening, though I did not have this problem with earlier versions.

As a temporary mitigation, please set build_ECHO=n in the mconfig file.

Will do, thanks. That will exclude the ECHO module from the final build 
I take it, right?

On a side note - since I am building/testing kernels for various 
purposes more often than compiling/building xta kernel modules (I am 
also pretty fed up with having to build/reinstall my buildsys packages 
every time I move to another kernel!), I decided to incorporate the xta 
kernel modules as a kernel patch instead of building them separately 
each time I build a kernel for testing.

I remember getting the above errors, but since it was the first time I 
have attempted to include the xta modules as a patch, I thought that I 
must be doing something wrong. In addition to the above errors I also 
got a separate error, which stemmed from one of the xta kernel modules 
(I think it was DNETMAP) using/depending on a separate .o/.so kernel 
file being built prior to it, hence a few other unresolved symbols 
during linking. It was the reason I abandoned this effort pretty quickly.

Has this been attempted before - to include the xta modules as part of 
the kernel? If there is an interest, I could dig in again to see what 
other linking errors was I getting - just let me know.

Forgot to add - for two of the xta modules (don't remember which ones 
though) there were errors that these are already in the kernel, so 
perhaps a logic in their code/Makefile could be added to exclude 
themselves from building if a decent/recent version of the kernel exists.
