Public bug reported:

Request to backport Kernel changes from Kernel 4.5 to lts kernel 4.4 for
xenial and if possible to lts kernel for 14.04

Change upstream:
netfilter: Set /proc/net entries owner to root in namespace
http://git.kernel.org/cgit/linux/kernel/git/pablo/nf-next.git/commit/?id=f13f2aeed154da8e48f90b85e720f8ba39b1e881

This is the Kernel-side part of the fix for "iptables-save does not work inside lxd containers"
https://github.com/lxc/lxd/issues/1978#issuecomment-220998013

The necessary changes in lxc landed in lxc/lxd
https://github.com/lxc/lxc/pull/1014 and is available in version 2.0.1,
currently in xenial-proposed.

It would be great if this would be backported asap. As it allows to
manage the firewall within lxd instances using Puppet and probably other
configuration management systems. And to use iptables-save manually
