Open Stack

I marked the OSSA task as invalid because we won't be releasing a
security advisory. The bug task for this in Nova is still very much
open.

Title:
  seed method brings potential security issue

Status in OpenStack Compute (Nova):
  New
Status in OpenStack Security Advisories:
  Invalid

Bug description:
  In the /cinder/transfer/apil.py, line 86, the source code is below

             random.seed(datetime.datetime.now().microsecond)

  This code is using seed method to generate a random number, Standard
  random number generators should not be used to generate randomness
  used for security reasons. For security sensitive randomness a
  crytographic randomness generator that provides sufficient entropy
  should be used.
