Hi Pablo,
Please consider to apply the next patch to your nf tree. It should be applied
to all stable branches to which the patch "netfilter: ipset: fix race condition
between swap/destroy and kernel side add/del/test", commit 28628fa9 was added.
* The synchronize_rcu() call added to the swap function to prevent the race
condition makes it too slow. The race can be prevented by using call_rcu()
in the destroy function instead.
Best regards,
Jozsef
