Unable to create/allocate specific floating ip

[Christoph Thiel]

http://docs.openstack.org/api/openstack-network/2.0/content/floatingip_create.html mentions:

An address for the floating ip will be automatically allocated, unless the floating_ip_address attribute is specified in the request body. If the requested floating IP address does not fall in the external network's subnet range, a 400 error will be returned. If the requested floating IP address is already in use, a 409 error code will be returned.

This is also described in https://wiki.openstack.org/wiki/Quantum/APIv2-specification

However, the quantum code reads differently :( I'll propose a fix to quantum and quantumclient shortly.

Patch https://review.openstack.org/70286 has been merged, and I have pulled it into a Juno installation. But it does not work. I get the following in Neutron's server.log:

2015-01-21 10:04:39.265 16040 ERROR neutron.api.v2.resource [req-4b09ceb9-86f1-42d4-b1f9-117ae6ed9026 None] create failed

The request was from user=admin tenant=admin.

Also, I am surprised at the following part of the patch:

786 + if fip.get('floating_ip_address'):
787 + port['fixed_ips'] = [
788 + {'ip_address': fip['floating_ip_address']}]

Is there a confusion there between floating and fixed?

Are there any tempest tests of this functionality?

[fujioka yuuichi (fujioka-yuuichi-d)]

did you modify "neutron/db/l3_db.py" only? "neutron/extensions/l3.py" should be fixed as the same as https://review.openstack.org/#/c/70286/22/.

[Mike Spreitzer (mike-spreitzer)]

Yes, I applied the whole patch. I looked in neutron/db/l3_db.py and saw that it has the revised code in it.

[Mike Spreitzer (mike-spreitzer)]

I must have goofed up my testing somehow. Now it is working for me.

[fujioka yuuichi (fujioka-yuuichi-d)]

"create_floatingip:floating_ip_address": "rule:admin_only" is included in "/etc/neutron/policy.json" ?
