<h2>NAME

<p style="margin-left:11%; margin-top: 1em">mencoder_selinux
&minus; Security Enhanced Linux Policy for the mencoder
processes</p>

<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>



<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the mencoder processes via flexible mandatory
access control.</p>

<p style="margin-left:11%; margin-top: 1em">The mencoder
processes execute with the mencoder_t SELinux type. You can
check if you have these processes running by executing the
<b>ps</b> command with the <b>&minus;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 mencoder_t</b></p>

<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>


<p style="margin-left:11%; margin-top: 1em">The mencoder_t
SELinux type can be entered via the <b>mencoder_exec_t</b>
file type.</p>

<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the mencoder_t domain are the
following:</p>


<p style="margin-left:11%; margin-top: 1em">/usr/bin/mencoder</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>&minus;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
mencoder policy is very flexible allowing users to setup
their mencoder processes in as secure a method as
possible.</p>

<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for mencoder:</p>


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

<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a mencoder_t</b> can be used to make
the process type mencoder_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. mencoder
policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run mencoder with the
tightest access possible.</p>

<p style="margin-left:11%; margin-top: 1em">If you want to
deny user domains applications to map a memory region as
both executable and writable, this is dangerous and the
executable should be reported in bugzilla, you must turn on
the deny_execmem boolean. Disabled by default.</p>

<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
deny_execmem 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
determine whether mplayer can make its stack executable, you
must turn on the mplayer_execstack boolean. Disabled by
default.</p>

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

<p style="margin-left:11%; margin-top: 1em">If you want to
allow all unconfined executables to use libraries requiring
text relocation that are not labeled textrel_shlib_t, you
must turn on the selinuxuser_execmod boolean. Disabled by
default.</p>

<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
selinuxuser_execmod 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>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>


<p style="margin-left:11%; margin-top: 1em">The SELinux
process type mencoder_t can manage files labeled with the
following file types. The paths listed are the default paths
for these file types. Note the processes UID still need to
have DAC permissions.</p>


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


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


<p style="margin-left:11%; margin-top: 1em">/home/[^/]+/.mplayer(/.*)?</p>


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


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


<p style="margin-left:11%; margin-top: 1em">/home/[^/]+/.+</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>&minus;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
mencoder policy is very flexible allowing users to setup
their mencoder processes in as secure a method as
possible.</p>

<p style="margin-left:11%; margin-top: 1em"><i>The
following file types are defined for mencoder:</i></p>


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

<p style="margin-left:11%; margin-top: 1em">- Set files
with the mencoder_exec_t type, if you want to transition an
executable to the mencoder_t domain.</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
to use the <b>semanage fcontext</b> command. This will
modify the SELinux labeling database. You will need to use
<b>restorecon</b> to apply the labels.</p>

<h2>COMMANDS
<a name="COMMANDS"></a>
</h2>


<p style="margin-left:11%; margin-top: 1em"><b>semanage
fcontext</b> can also be used to manipulate default file
context mappings.</p>

<p style="margin-left:11%; margin-top: 1em"><b>semanage
permissive</b> can also be used to manipulate whether or not
a process type is permissive.</p>

<p style="margin-left:11%; margin-top: 1em"><b>semanage
module</b> can also be used to enable/disable/install/remove
policy modules.</p>

<p style="margin-left:11%; margin-top: 1em"><b>semanage
boolean</b> can also be used to manipulate the booleans</p>


<p style="margin-left:11%; margin-top: 1em"><b>system-config-selinux</b>
is a GUI tool available to customize SELinux policy
settings.</p>
