I'll start by saying that we don't need this ported to icehouse as we've
included it in our distro, as Alan suggested.

However, I would like to explain why we needed it.  We do generate
cert files for the controller node.  However, for cases where the different
services are all running on the controller node, we use 127.0.0.1 as the
address they communicate on.  Since the cert was based on hostname,
this will fail unless we have the api_insecure flag set.  And since we're
communicating on 127.0.0.1, it's ok to ignore ssl errors.

Since this is in Juno, and we've patched it in Icehouse for our distro, we
have no pressing need to backport this one.  Thanks for keeping an
eye on it!

I think you're right that 1309694 can be worked around by using system
cert store.
Disabling cert check bug 1306822 is definitely not needed - why would
you use certs if you don't check them?
So unless more justification is provided in the bugs (importance of
both is Undecided) I don't think we have the case for granting the
exception.

Distributions are of course free to take those patches, if it suits
their policies.
BTW having such backports proposed is fine even if denied for stable
merge, we can use stable reviews as a mean to share patches among
distros.

Currently yes, only Neutron has a new feature in Icehouse to send port
events to Nova but Cinder will need to same to properly fix the race
with volumes during VM setup.
