Request for -stable inclusion (xt_TCPMSS)

Hi David,

Please queue 2638fd0f92d4 ("netfilter: xt_TCPMSS: add more sanity tests on tcph->doff")
for -stable.
It fixes hard to debug crashes in production, that can be triggered by
remote peers.

Regards,

Guillaume

What stable kernels you want this in? Does this apply cleanly to them
all?

I can route this for you directly to stable@vger.kernel.org once we
sort out these questions.

Thanks!

I need it (and reviewed/tested it) for 4.9. But the patch applies
cleanly and looks necessary for all stable versions >= 3.16 (not
tested though).

Great, thanks Pablo. But do you mean I should have Cc-ed
stable@vger.kernel.org directly?

Pablo handles netfilter -stable submissions, so please ask him.

Thank you.
