Public bug reported:

Related bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2244365

During the port bulk creation, before the port DB registers are created,
there is a method that pre-creates the port MAC address and the IPAM
allocations [1]. If one of the requested "fixed_ips" is incorrect (for
example, the IP address is out of the subnet CIDR), the method will
raise an exception. However, the IPAM allocations created previously
will remain in the DB.

Steps:
$ openstack create network net1
$ openstack subnet create --subnet-range 10.0.50.0/24 --network net1 snet1
$ OS_TOKEN=`openstack token issue | grep "| id" | tr -s " " | cut -f4 -d" "`
$ curl -H "X-Auth-Token:$OS_TOKEN" -X POST http://192.168.10.100:9696/networking/v2.0/ports
    -d '{"ports": [
      {"network_id": <net_id>,
       "fixed_ips": [{"subnet_id": <subnet_id>, "ip_address": "10.0.50.10"}]},
      {"network_id": <net_id>,
       "fixed_ips": [{"subnet_id": <subnet_id>, "ip_address": "10.0.51.20"}]}]}'


Note that the second IP address 10.0.51.20 is not in the subnet CIDR 10.0.50.0/24. The IPAM allocation for 10.0.50.10 (the first request), will remain in the DB.

Title:
  [IPAM] During port bulk creation, if a "fixed_ip" request is
  incorrect, the previous IPAM allocations generated are not deleted
