after some thoughts, i tend to think it's a bug in neutron.
it shouldn't populate tenant_id for resources which doesn't have it.
how do you think?

[Kengo Hobo (hobo-kengo)]

Yes, I agree with you.
Probably in current neutron, there is no resource that matches following conditions.
* the resource could be created by user(admin or tenant).
* the resource doesn't relate to tenant.

When create resource, tenant_id is added to request body in populate_tenant_id method in attributes.py.
So in networking-midonet, we address this bug with some workaround(add tenant_id to extensions) because this bug is critical, I think. And we report a bug along this to neutron in parallel.

Takashi,

I'm sorry, I haven't filed yet.
I tried to find related modification in neutron core.
However, I could not find it.

I filed the bug just now with following description.
Could you confirm it?
