[parisc-linux] ip6tables problem

[parisc-linux] ip6tables problem

[BUCH-PEDERSEN,LEIF (HP-France,ex1)]

For some time I have been running a customized version of a 2.4.18 kernel
with ipv6 enabled on. Now I want to look at the use of iptables (ip6tables).


To do this have enabled ipv6 netfilter configuration options and compiled
several versions of the kernel (everything compiled into the kernel,
netfilter as modules, kernel based on 2.4.19-pa5 from parisc-linux.org). In
all cases the kernel compiles but ip6tables does not work. 

Using the kernel with modules I have been able to boil down the problem to a
problem with the module ip6table_filter. 

When I am doing 'insmod ip6table-filter' I get a message :
ip6table_filter.o: init_module: Invalid argument

And this is where I am stuck. There is no more information in syslog or
dmesg. Any ideas ?

PS: ip6table_filter loads OK using a 2.4.18 kernel on a machine with a
Pentium processor.

Not many people use IPV6 (ie run it on their machines).
I'm not aware of anyone trying it for parisc-linux.

Add printk() calls in the offending module.

	rmmod ip6table-filter
	vi net/ipv6/netfilter/ip6table_filter.c
	make modules
	make modules_install
	modprobe ip6table-filter 

until you can narrow down what's failing in init() routine.
See module_init(init) line at the bottom of ip6table_filter.c.

suggests parisc is missing some arch specific IPV6 support.

I'm running an IPv6 cluster on two 715 HPPA machines in production use
(using heartbeat and an IPv6 IP address takeover script). Yet another 720
HPPA machine is running for development and testing and partly builds the
stuff for the Debian IPv6 project (http://debian.fabbione.net).

However, i'm not using the ip6tables on that boxes as all three of them
are behind dedicated packet filters...

At least i can confirm the original problem (just tried it on the 720).

 I have built and use 2.4.19-pa22 kernels with the latest stable usagi
patch applied, with only one reject on some network driver I do not
possess . I had to disable many netfilter for ipv6 options in order for
the kernel to compile . And those that I had enabled dont seem to work :)
 Currently using ipv6 on two 715/33 and one 715/50 ...and it works
perfectly:)
