Date: Fri, 25 Jul 2014 11:35:39 -0700 From: Linus Torvalds <torvalds@...ux-foundation.org> To: Eric Dumazet <eric.dumazet@...il.com> Cc: Jeffrey Knockel <jeffk@...unm.edu>, David Miller <davem@...emloft.net>, netdev <netdev@...r.kernel.org>, "Jedidiah R. Crandall" <crandall@...unm.edu>, Willy Tarreau <w@....eu>, "security@...nel.org" <security@...nel.org> Subject: Re: [PATCH net] ip: make IP identifiers less predictable On Fri, Jul 25, 2014 at 11:09 AM, Eric Dumazet <eric.dumazet@...il.com> wrote: > > We might change the hash to use both daddr & saddr to increase > protection. .. and maybe protocol too, so that you can't easily use icmp echo packets to do it for udp packets etc. The underlying jhash is jhash_3words(), so that would actually be fairly natural for at least ipv4 (the ipv6 case I didn't look at).
