libipt_multiport: getsockopt failed strangely: Invalid argument

[Arnaud Fontaine <arnaud@andesi.org>]

Hello,

When I try to use the '-m multiport' argument, I have the following
error message:

# /sbin/iptables -A INPUT -p tcp -m multiport --sports \
                 ssh,www,imap2,pop3,domain,https,smtp,auth -m state \
                  --state NEW,ESTABLISHED,RELATED -j ACCEPT
getsockopt failed strangely: Invalid argument

strace results:

write(2, "getsockopt failed strangely: Inv"..., 46getsockopt failed strangely: Invalid argument) = 46                             

This error happens only with 2.6.17 and 2.6.18, using 2.6.15 it works
fine. I don't know at all how I could identify the problem. I'm using
Debian GNU/Linux with sparc64-smp Linux kernel and iptables 1.3.6. I
hope that i have sent this mail to the proper mailing list.
