[Bug 2060808] Re: already associated floating ip can be associated to another server without check or warning

 

Well, for the PUT operation it's the same thing for neutron (and the
same call here [0]), whether the port is null or another valid port id,
neutron is going to update it.

As I mentioned in the other bug, it will be up to the Nova team to
determine if it's API is working correctly.

[0] PUT
/networking/v2.0/floatingips/1875754d-7b9f-47c2-9c0d-83eafd1a0a76

Title:
  already associated floating ip can be associated to another server
  without check or warning

Status in neutron:
  Opinion
Status in OpenStack Compute (nova):
  New

Bug description:
  When adding a floating ip to a server the following CLI command is used: 
  openstack server add floating ip <server> <floating ip>

  When nova was still handling the floating IPs in the backend, it seems there was a check, whether the floating IP was already associated to an instance:
  https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/floating_ips.py#L243

  And as a user I don't want to accidentally associate a floating IP to
  a server, that is already associated to another.

  But that is right now the case:

  
  Steps to reproduce:

  1. Have two servers, one with an associated floating ip (server A) and one without (server B)
  2. execute the command: openstack server add floating ip <server B> <floating IP from server A>
  3. now server B has a floating IP associated but server A has not.

  Example:

  As can be seen in the debug output, after checking whether floating ip
  and server exist and getting the correct port, the floating ip is just
  set on that port. There is no check, if the floating ip was already
  associated to another port or server.

  This has positive and negative implications:
  Positive:
  Transferring a floating ip from one server to another is just one step instead of two

  Negative:
  If a user of the CLI just checks its floating IPs to use an unassociated one for a new server, the mistake of reading the wrong line can occur. In that moment, an already associated floating IP is mistakenly transferred from one server to another.
