Patrole - RBAC Integration Tempest Plugin
=========================================

Patrole is a security validation tool for verifying that Role-Based Access
Control is correctly configured and enforced in a system. It runs Tempest-based
API tests using specified RBAC roles, thus allowing deployments to verify that
only intended roles have access to those APIs.

Patrole currently offers testing for the following OpenStack services: Nova,
Neutron, Glance, Cinder and Keystone.

Features
--------
* Validation of default policy definitions located in policy.json files.
* Validation of in-code policy definitions.
* Validation of custom policy file definitions that override default policy
  definitions.
* Built-in positive and negative testing. Positive and negative testing
  are performed using the same tests and role-switching.
* Valdation of custom roles as well as default OpenStack roles.

.. note::

    Patrole does not yet support policy.yaml files, the new file format for
    policy files in OpenStack.

How It Works
------------
Patrole leverages ``oslo.policy`` (OpenStack's policy enforcement engine) to
determine whether a given role is allowed to perform a policy action, given a
specific role and OpenStack service. The output from ``oslo.policy`` (the
expected result) and the actual result from test execution are compared to
each other: if both results match, then the test passes; else it fails.

Quickstart
----------
Tempest is a prerequisite for running Patrole. If you do not have Tempest
installed, please reference the official Tempest documentation for guidance.

Assuming Tempest is installed, the simplest way to configure Patrole is:

1. Open up the ``tempest.conf`` configuration file and include the following
settings:

.. code-block:: ini

    [rbac]
    enable_rbac = True
    rbac_test_role = admin

These settings tell Patrole to run RBAC tests using the "admin" role (which
is the default admin role in OpenStack) to verify the default policy
definitions used by OpenStack services. Specifying a different role
for ``rbac_test_role`` will run Patrole tests against that role. For additional
information about Patrole's configuration settings, please refer to
:ref:`patrole-configuration` and :ref:`patrole-sampleconf` for a sample
configuration file.

2. You are now ready to run Patrole. To do so, you can use any testr-based test
runner::

    $ testr run patrole_tempest_plugin.tests.api

or::

    $ ostestr --regex '(?!.*\[.*\bslow\b.*\])(^patrole_tempest_plugin\.tests\.api)'

It is also possible to run Patrole using tox::

    tox -eall-plugin -- patrole_tempest_plugin.tests.api

Release Versioning
------------------
`Patrole Release Notes <https://docs.openstack.org/releasenotes/patrole/>`_
shows which changes have been released for each version.

Patrole's release versioning follows Tempest's conventions. Like Tempest,
Patrole is branchless and uses versioning instead.
