Iptables-1.2.9/10 compile failure with linux 2.6.7 headers

Iptables-1.2.9/10 compile failure with linux 2.6.7 headers

[Andrew Walrond]

The addition of a
	__user
attribute to a line in
	linux-2.6.7/include/linux/netfilter_ipv4/ip_tables.h
causes iptables build to fail unless I export
	CC="gcc -D__user= "

Presumably ip_tables.h should include a header defining __user, or iptables 
should include the relevant header before ip_tables.h ?

Sorry if this has already been reported; Archive search found nothing on 
either ML.

Iptables should be using linux-libc-headers headers instead of kernel 
headers.

Remove -I$(KERNEL_DIR)/include from your makefile, see this patch here: 
http://ep09.pld-linux.org/~mmazur/linux-libc-headers/patches/iptables.patch 
<http://ep09.pld-linux.org/%7Emmazur/linux-libc-headers/patches/iptables.patch>

Is this acquired knowledge, or new Netfilter policy?
How dependant are the iptables tools on the specifc kernel running?

Ie
Can I build iptables for use on 2.6.7 kernel with 2.6.6 linux-libc-headers? 
(probably)

But could I build iptables for 2.6.7 kernel with 2.4.20 linux-libc-headers? 
(probably not?)

The INSTALL file states specifically to use 
KERNEL_DIR=<<where-you-built-your-kernel>>

The current linux libc headers package is much more frequently updated 
and closely matches released kernels.  LLH is a sanitized linux headers 
package and is currently based on 2.6.6 headers.

Yes you can build iptables on 2.6.6 for a 2.6.7 kernel.  I have built 
iptables once or twice a year and built kernels once or twice a week.  
Iptables continues to work fine.
