Subject: Re: [PATCHv3 net 1/3] openvswitch: Fix double-free on ip_defrag()

From: Joe Stringer <>
Date: Sun, 25 Oct 2015 20:21:48 -0700

> If ip_defrag() returns an error other than -EINPROGRESS, then the skb is
> freed. When handle_fragments() passes this back up to
> do_execute_actions(), it will be freed again. Prevent this double free
> by never freeing the skb in do_execute_actions() for errors returned by
> ovs_ct_execute. Always free it in ovs_ct_execute() error paths instead.
> Fixes: 7f8a436eaa2c ("openvswitch: Add conntrack action")
