<p style="margin-left:11%; margin-top: 1em">mpd_selinux
− Security Enhanced Linux Policy for the mpd
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the mpd processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The mpd
processes execute with the mpd_t SELinux type. You can check
if you have these processes running by executing the
<b>ps</b> command with the <b>−Z</b> qualifier.</p>
<p style="margin-left:11%; margin-top: 1em">For
example:</p>
<p style="margin-left:11%; margin-top: 1em"><b>ps -eZ |
grep mpd_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The mpd_t
SELinux type can be entered via the <b>mpd_exec_t</b> file
type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the mpd_t domain are the following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/bin/mpd</p>
<h2>PROCESS TYPES
<a name="PROCESS TYPES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux defines
process types (domains) for each process running on the
system</p>
<p style="margin-left:11%; margin-top: 1em">You can see the
context of a process using the <b>−Z</b> option to
<b>ps</b></p>
<p style="margin-left:11%; margin-top: 1em">Policy governs
the access confined processes have to files. SELinux mpd
policy is very flexible allowing users to setup their mpd
processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for mpd:</p>
<p style="margin-left:11%; margin-top: 1em"><b>mpd_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a mpd_t</b> can be used to make the
process type mpd_t permissive. SELinux does not deny access
to permissive process types, but the AVC (SELinux denials)
messages are still generated.</p>
<h2>BOOLEANS
<a name="BOOLEANS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux policy
is customizable based on least access required. mpd policy
is extremely flexible and has several booleans that allow
you to manipulate the policy and run mpd with the tightest
access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
determine whether mpd can traverse user home directories,
you must turn on the mpd_enable_homedirs boolean. Disabled
by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
mpd_enable_homedirs 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
determine whether mpd can use cifs file systems, you must
turn on the mpd_use_cifs boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
mpd_use_cifs 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
determine whether mpd can use nfs file systems, you must
turn on the mpd_use_nfs boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
mpd_use_nfs 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
dontaudit all daemons scheduling requests (setsched,
sys_nice), you must turn on the daemons_dontaudit_scheduling
boolean. Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
daemons_dontaudit_scheduling 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow all domains to execute in fips_mode, you must turn on
the fips_mode boolean. Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
fips_mode 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow system to run with NIS, you must turn on the
nis_enabled boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
nis_enabled 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
support NFS home directories, you must turn on the
use_nfs_home_dirs boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
use_nfs_home_dirs 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
support SAMBA home directories, you must turn on the
use_samba_home_dirs boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
use_samba_home_dirs 1</b></p>
<h2>PORT TYPES
<a name="PORT TYPES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux defines
port types to represent TCP and UDP ports.</p>
<p style="margin-left:11%; margin-top: 1em">You can see the
types associated with a port by using the following
command:</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
port -l</b></p>
<p style="margin-left:11%; margin-top: 1em">Policy governs
the access confined processes have to these ports. SELinux
mpd policy is very flexible allowing users to setup their
mpd processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
port types are defined for mpd: <b><br>
mpd_port_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Default Defined
Ports:</p>
<p style="margin-left:26%;">tcp 6600</p>
<h2>MANAGED FILES

</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type mpd_t can manage files labeled with the

for these file types. Note the processes UID still need to
have DAC permissions.</p>

<h2>FILE CONTEXTS
<a name="FILE CONTEXTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux
requires files to have an extended attribute to define the
file type.</p>
<p style="margin-left:11%; margin-top: 1em">You can see the
context of a file using the <b>−Z</b> option to
<b>ls</b></p>
<p style="margin-left:11%; margin-top: 1em">Policy governs
the access confined processes have to these files. SELinux
mpd policy is very flexible allowing users to setup their

<p style="margin-left:11%; margin-top: 1em"><b>EQUIVALENCE
DIRECTORIES</b></p>
<p style="margin-left:11%; margin-top: 1em">mpd policy
stores data with multiple different file context types under
the /var/lib/mpd directory. If you would like to store the
data in a different directory you can use the semanage
command to create an equivalence mapping. If you wanted to
store this data under the /srv directory you would execute
the following command:</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
fcontext -a -e /var/lib/mpd /srv/mpd <br>
restorecon -R -v /srv/mpd</b></p>
<p style="margin-left:11%; margin-top: 1em"><b>STANDARD
FILE CONTEXT</b></p>
<p style="margin-left:11%; margin-top: 1em">SELinux defines
the file context types for the mpd, if you wanted to store
files with these types in a different paths, you need to
execute the semanage command to specify alternate labeling
and then use restorecon to put the labels on disk.</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
fcontext -a -t mpd_var_run_t
’/srv/mympd_content(/.*)?’ <br>
restorecon -R -v /srv/mympd_content</b></p>
<p style="margin-left:11%; margin-top: 1em">Note: SELinux
often uses regular expressions to specify labels that match
multiple files.</p>
<p style="margin-left:11%; margin-top: 1em"><i>The

<p style="margin-left:11%; margin-top: 1em"><b>mpd_data_t</b></p>

<p style="margin-left:11%; margin-top: 1em">Note: File
context can be temporarily modified with the chcon command.
If you want to permanently change the file context you need
