ipaddr is not assigned when creating a port on shared network with different tenant_id

[Akihiro Motoki]

When I create a port on a shared network with different tenant_id,
IP address is not assigned to the port created.

After ./stack.sh,
(1) (User=admin/Tenant=admin) creates public network 'pub1' and subnet.
(2) (User=demo/Tenant=invisible_to_admin) can see 'pub1'. It is ok.
(3) Then, (User=demo/Tenant=invisible_to_admin) creates a port on
    public network 'pub1'.
(4) The port creation succeeds but fixed_ips are not assigned.

I expects IP address will be assinged on the created port.

In the above case, get_subnets() in db_base_plugin_v2 returns an empty list.
Since subnet has no attribute 'shared', _model_query() for subnets queries "subnets" table with tenant_id.
It seems "shared" attribute is necessasry for "subnets" table.

I hope my understanding of public network is correct.

The commandline above is wrong.

I will look into this as soon as possible.
I suspect something in the underlying data model is preventing us to fetch all subnets for a given shared network.
What is probably happening is that only the subnets owned by the tenant which owns the network are being fetched.

[Salvatore Orlando (salvatore-orlando)]

We need to ensure a tenant is able to access subnets on a shared network.
Given the current default policies, it makes sense to assume that the owner of a shared network will want to give users access to all subnets in that network.

    Fix IP allocation on shared networks ports.
