# Node ID 294fc8fc4ba05c1fe91754dfe3b770834c56231b

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.
