Keir Fraser 3129d6f2ea xsm, flask: sample flask policy
- The patch includes a policy for xen that can be booted into
  enforcing mode and supports creation and management of
  paravirtualized guests.  The policy follows the dom0/domU usage
  model, extension to other models or the addition of management or IO
  permissions should be much more straightforward now. The option
  flask_enforcing=1 can be passed on the xen line in grub to boot
  into enforcing mode.

- The policy provides a basic policy for booting the platform and
  creating a domU with the label system_u:object_r:domU_t.  The policy
  can be easily extended to support new types by modifying the xen.te
  source file.

- The policy includes some basic macros which may be helpful in
  extending the policy.

- The policy is compatible with and requires the most recent XSM
  patch, xsm-flask-io-sysctl-hooks-090308.diff.

- The policy is not built as part of the make all as it requires the
  SELinux policy compiler which may/may not be installed on all
  systems.  Users must go into the tools/flask/policy directory and
  explicitly compile the policy.

# Makefile for the security policy.

# Targets:
#
# install - compile and install the policy configuration, and context files.
# load - compile, install, and load the policy configuration.
# reload - compile, install, and load/reload the policy configuration.
# policy - compile the policy configuration locally for testing/development.
#
# The default target is 'policy'.

# Distribution
# Some distributions have portions of policy
