Mailing List Archive: Problems with Kernel 2.6.22.1

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

having updated my kernel from 2.6.19.2 to 2.6.22.1 both taken as vanilla
source from kernel.org, I now receive errors when trying to insert rules
using the state or conntrack modules. I expect other extensions to fail
as well. The produced error messages suggest some incompatibility
between the kernel and the userspace iptables:

# iptables -v -A FORWARD -j ACCEPT -m state --state RELATED,ESTABLISHED
ACCEPT all opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 state
RELATED,ESTABLISHED
iptables: Invalid argument

# iptables -v -A FORWARD -j ACCEPT -m conntrack --ctstate
RELATED,ESTABLISHED
ACCEPT all opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 ctstate
RELATED,ESTABLISHED
iptables: Invalid argument

This problem occurs with both the iptables v1.3.6 coming with Debian and
a self-compiled iptables v1.3.8 from the netfilter.org download page.

Is any such issue known? May there be any non-automatic dependencies in
the kernel configuration going beyond:

CONFIG_NETFILTER_NETLINK=y
CONFIG_NF_CONNTRACK_ENABLED=y
CONFIG_NF_CONNTRACK=y
CONFIG_NETFILTER_XT_MATCH_CONNTRACK=y
CONFIG_NETFILTER_XT_MATCH_STATE=y

Thanks,
Thomas

Do you also have CONFIG_NF_CONNTRACK_IPV4 enabled?
