Title:
  Wrong CIDR configuration in subnet will cause all IP-related functions
  invalid.

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  Now there’s no restrict check for CIDR during subnet creation.

  If we create a subnet with wrong CIDR address-pool, like 10.0.1.1/24,
  the IP valid-check will always return False [def _check_subnet_ip() in
  db_base_plugin_v2.py].

  This problem will cause all IP-related functions (like, vm creation in
  Nova, port creation in Quantum, etc.) fail when a fixed-IP pointed in
  request.

  Thanks~
