SLES11 SP2/SP3 - Using ipset to create user-defined IP sets for iptables results in : "No chain/target/match by that name".

This document (7014180) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11 Service Pack 2
SUSE Linux Enterprise Server 11 Service Pack 3


Situation

Using 'ipset' to create a new user-defined IP set for use with 'iptables', results results in error:
"No chain/target/match by that name"

Resolution

This has been resolved with a PTF for the current kernel, and will be resolved in a future kernel release.

Cause

The error is caused by fact that the iptables (user space) module ipt_set was available in the SLE kernel, but the netfilter (kernel) module xt_set was only available in the (unsupported) kernel-*-extra packages.

Additional Information

The problem can easily be duplicated using both SUSE Linux Enterprise 11 SP2 and SP3 with the iptables & ipset packages installed.

In a terminal window, type for example:
ipset -N sftpext hash:ip
and
iptables -A INPUT -m set --match-set sftpext src -j ACCEPT

This will result in the following message :
"No chain/target/match by that name"

Verifying the same IP set once again seems to indicate the IP set is valid:
ipset -N sftpext hash:ip
Results in :       
ipset v6.12: Set cannot be created: set with the same name already exists
