Open Stack

The distro fix for this issue was a patched python that removes the bad
SSL versions. I'm not convinced we should be in the business of working
around that at the openstack layer.

Bug description:
  We configure keystone to use SSL always. Due to the poodle issue, I was trying to configure keystone to disable SSLv3 completely. 
  http://googleonlinesecurity.blogspot.fi/2014/10/this-poodle-bites-exploiting-ssl-30.html
  https://www.openssl.org/~bodo/ssl-poodle.pdf

  It seems that keystone has no support for configring SSL versions, nor
  ciphers.

  If I'm not mistaken the relevant code is in the start function in
  common/environment/eventlet_server.py

  It calls 
  eventlet.wrap_ssl
  but with no SSL version nor cipher options. Since the interface is identical, I assume it uses ssl.wrap_socket. The default here seems to be  PROTOCOL_SSLv23 (SSL2 disabled), which would make this vulnerable to the poodle issue.

  SSL conifgs should probably be possible to be set in the config file
  (with sane defaults), so that current and newly detected weak ciphers
  can be disabled without code changes.
