Comment 23 for bug 994931

I have prepared a test 3.13 kernel (for Trusty) which reverts the Ubuntu-specific patch and adds the set of mainline patches that obviate these issues in Utopic and newer versions. My cursory testing suggests that it resolves both this bug ("drops all IPv6 addresses") and the problem that the Ubuntu-specific patch addressed ("make use_tempaddr work as documented").

The test kernel package, for Trusty amd64 systems only, is here (install with "dpkg -i thisfile.deb"):
http://kernel.ubuntu.com/~kamal/lp994931-ipv6/linux-image-3.13.0-46-generic_3.13.0-46.75+lp994931_amd64.deb

We'd like feedback from affected parties who can test this on Trusty. Does that kernel resolve your issue, and do you observe any obvious IP-related trouble with it?

For reference, the source code branch for that Trusty test kernel is here:
http://kernel.ubuntu.com/git?p=kamal/ubuntu-trusty.git;a=shortlog;h=refs/heads/lp994931-ipv6

A resolution of this issue for 3.2-based Precise is still being investigated.
