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

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



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

<p style="margin-left:11%; margin-top: 1em">The
systemd_notify processes execute with the systemd_notify_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 systemd_notify_t</b></p>

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


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

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


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

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


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

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

<p style="margin-left:11%; margin-top: 1em">If you want to
allow users to resolve user passwd entries directly from
ldap rather then using a sssd server, you must turn on the
