So, in my mind this isn't really an OpenStack bug. It's a Linux bug that just so happens to be hurting OpenStack deployers that want to do IPv6 related things. I think this bug can be closed, since the real fix is "Wait until distros start deploying the fix" - which yes is a long time away - unless someone backports. Regardless, more of a kernel issue than Nova or OpenStack.
A fix to Netfilter was merged into Linux Kernel version 4.2:
