=========
SEModules
=========

.. versionadded:: 1.3.0

The SEModules plugin handles SELinux module entries.  It supports
group- and host-specific module versions, and enabling/disabling
modules.

You can use ``selinux_baseline.py`` located in the tools/ directory to
create a baseline of all of your installed modules.

See :ref:`server-selinux` for more information.

Usage
=====

To use the SEModules plugin, first do ``mkdir
/var/lib/bcfg2/SEModules``.  Add ``SEModules`` to your ``plugins``
line in ``/etc/bcfg2.conf`` and restart bcfg2-server.

The SEModules directory contains modules in a layout similar to the
Cfg plugin: at the top level, SEModules should contain directories
named after the modules you want to install, and each of those
directories can contain a global module, plus any number of group- and
host-specific modules.  For instance::

    $ ls -F SEModules
    foo.pp/  bar.pp/
    $ ls SEModules/foo.pp/
    foo.pp
    foo.pp.G50_server
    foo.pp.H_baz.example.com

For more information on this directory layout, see
:ref:`server-plugins-generators-cfg`.

Entries
=======

SEModules handles ``<SELinux>`` entries with the ``module`` type.  For
instance:

.. code-block:: xml

    <Bundle name="foo">
      <SELinux type="module" name="foo.pp"/>
    </Bundle>

The ``.pp`` extension is optional.

.. note::

    If you use a ``BoundSELinux`` tag, you must *not* include the
    ``.pp`` extension.  This is not recommend, though.

You can also install a disabled module:

.. code-block:: xml

    <SELinux type="module" name="foo" disabled="true"/>
