[Bug 1430345] Re: Manually created port by admin can be assigned as a second gateway to an existing router
As per the discussion with kevinbenton on
https://review.openstack.org/368414, it seems that the code has been
changed, which allows a port to be added if the device owner is
network:router_gateway, but the code [1] will change the device owner to
network:router_interface.

Title:
Manually created port by admin can be assigned as a second gateway to
an existing router
Status in neutron:
Fix Released
Bug description:
____________
Description:
As an admin one can manually create a port on a network and assign it to a router (which already have a gateway) as a gateway by adding "Device Owner" = "network:router_gateway" and "Device ID" = "<router ID>"
basically I see two issues here:
1. When Manually creating a port on an external network it cannot be deleted via API access (Horizon or CLI command)
2. The manually created port can be assign as a "Device Owner" = network:router_gateway to a router that already have a default gateway which cause one router to have two default gateways.
________________
Version-Release:
openstack 6.0.3-0
openstack-neutron-2014.2.2-3
horizon-2014.2.2-2
____________
Environment:
All-in-One
RHEL 7.1
___________________
Steps to Reproduce:
1. Create Neutron external network and a subnet
2. Create a router and set a gateway the external network
3. Add a port and assign it to the router you created with "Device Owner" = "network:router_gateway" and "Device ID" = "<router ID>"
4. Try to delete the manually created port
_______________
Actual results:
Port cannot be deleted with the following: Error: Failed to delete port: Port 0ff48364-dcb1-44a4-b064-b1df5e9cb911 has owner network:router_gateway and therefore cannot be deleted directly via the port API.
_________________
Expected results:
Port can be deleted
Cannot assign two gateways to one router.
