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.
Was it intententional to create the other bug? https:/
