That's why I vote to check out if it's possible/reasonable to backport this
series to the stable kernels.

I have backported to 4.0.y without major issue, so possible.

Sure, as this was likely one of the versions they've used to create the 
patch.

I did try on 3.1x and gave up.

It is a lot of changes,  so I don't think it is a good idea for -stable.

Depends on what you're expecting from a (stable) kernel.

The patch description mentions what happens when a system deals with a 
lot of other ipv6-systems and that problem is easy to exercise and to value.

Rating the information leak is harder, some people even won't understand 
that this might be a problem.

And now look at which kernel-versions are now used in new devices 
(likely something <= 3.10, which is more than two years old), how long 
they will be used, and make a guess about IPv6 usage in 5 years.

Anyway, I've no insights about all the politics happening in the 
background (e.g. stuff like the LTSI tree) and I've just wanted raise 
awareness about that (imho important) patch series.
