Subject: Re: [PATCH net] net: flow_dissector: fail on evil iph->ihl

From: Jason Wang <>
Date: Fri,  1 Nov 2013 15:01:10 +0800

> We don't validate iph->ihl which may lead a dead loop if we meet a IPIP
> skb whose iph->ihl is zero. Fix this by failing immediately when iph->ihl
> is evil (less than 5).
> This issue were introduced by commit ec5efe7946280d1e84603389a1030ccec0a767ae
> (rps: support IPIP encapsulation).
