IMHO this is not a bug in Oslo, but a feature request.  Please open a
blueprint against Oslo to track this work (I do agree that common code
to do validation is a good idea)  Obviously there is some significant
discussion needed first, so I would also suggest sending something to
openstack-dev on this topic.

Thanks.

Title:
  Name validations for compute resources

Status in Cinder:
  Confirmed
Status in OpenStack Identity (Keystone):
  New
Status in OpenStack Compute (Nova):
  Confirmed
Status in Oslo - a Library of Common OpenStack Code:
  Invalid

Bug description:
  There is no consistent validation for the 'name' parameter across
  compute resources. The following characters need to be validated in
  the input:

  1. One more whitespaces (like ' ' or '    ') -
  2. Leading or trailing whitespaces (like '   test123 ')

  Currently flavor name, volume name, role name, group name, security
  group name and keypair name accept input in each of the two cases (no
  validation).

  Adding the two cases above to name parameter validation would be useful.
  It makes sense to move this validation code to a common utility that can be used across all Create resource methods.
  Although the 'name' is not as significant the resource's ID, it does act as a label for the resource and should be validated properly.

  For example, from the dasbhboard, a role with a blank name, i.e single
  whitespace string like ' ' can be created. This get's stored in the
  keystone db as NULL and appears in the dashboard roles drop down
  during Create User as None. This behavior should be fixed.

  Refer:
  https://github.com/openstack/nova/blob/master/nova/compute/api.py#L3086
  _validate_new_keypair() can be moved to a common utility to provide
  'name' field validations.
