Title:
Users have cross-tenant visibility on images
Status in Glance:
Invalid
Bug description:
Using Kilo 2015.1.2 and Glance Client 0.17.0:
Using two users (demo in the demo tenant, alt_demo in the alt_demo
tenant, neither have the admin role), I am able to create an image
with is_public set to False as the demo user/tenant, and then show
data/use that image to create an instance as the alt_demo:
> env | grep OS_
OS_PASSWORD=secret
OS_AUTH_URL=http://localhost:5000/v2.0
OS_USERNAME=demo
OS_TENANT_NAME=demo
> glance image-create --container-format bare --disk-format raw --is-public false --name demo_image

+------------------+--------------------------------------+
The image then does not appear in image-list:

With --all-tenants, it appears

With image-show and the name, error message:
> glance image-show demo_image
No image with a name or ID of 'demo_image' exists.
With image-show and the uuid, data:

Now swap to alt_demo:
env | grep OS_
OS_PASSWORD=secret
OS_AUTH_URL=http://localhost:5000/v2.0
OS_USERNAME=alt_demo
OS_TENANT_NAME=alt_demo
Image list with --all-tenants shows the image even though it shouldn't.

Image-show with name returns error (correct):
> glance image-show demo_image
No image with a name or ID of 'demo_image' exists.
Attempting to boot an instance as alt_user with the image gives the error that it is not active, not that it wasn't found:
> nova boot --flavor 1 --image demo_image should_not_work
ERROR (BadRequest): Image 51215efe-3533-4128-a36f-a44e507df5d7 is not active. (HTTP 400) (Request-ID: req-44d95795-82ff-45f8-8945-faf430ddb5fc)
vs
> nova boot --flavor 1 --image foo should_not_work
ERROR (CommandError): No image with a name or ID of 'foo' exists.
Tempest tests that run expecting to not be able to access images
across tenants fail since the image can be used / queried.
