<h2>NAME

</h2>
<p style="margin-left:11%; margin-top: 1em">NetworkManager_dispatcher_chronyc_selinux
− Security Enhanced Linux Policy for the
NetworkManager_dispatcher_chronyc processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the NetworkManager_dispatcher_chronyc
processes via flexible mandatory access control.</p>
<p style="margin-left:11%; margin-top: 1em">The
NetworkManager_dispatcher_chronyc processes execute with the
NetworkManager_dispatcher_chronyc_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 NetworkManager_dispatcher_chronyc_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
NetworkManager_dispatcher_chronyc_t SELinux type can be
entered via the
<b>NetworkManager_dispatcher_chronyc_script_t</b> file
type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the NetworkManager_dispatcher_chronyc_t
domain are the following:</p>
<p style="margin-left:11%; margin-top: 1em">/etc/NetworkManager/dispatcher.d/20-chrony-dhcp,
/usr/lib/NetworkManager/dispatcher.d/20-chrony-dhcp,
/etc/NetworkManager/dispatcher.d/20-chrony-onoffline,
/usr/lib/NetworkManager/dispatcher.d/20-chrony-onoffline</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
NetworkManager_dispatcher_chronyc policy is very flexible
allowing users to setup their
NetworkManager_dispatcher_chronyc processes in as secure a
method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for
NetworkManager_dispatcher_chronyc:</p>
<p style="margin-left:11%; margin-top: 1em"><b>NetworkManager_dispatcher_chronyc_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a
NetworkManager_dispatcher_chronyc_t</b> can be used to make
the process type NetworkManager_dispatcher_chronyc_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.
NetworkManager_dispatcher_chronyc policy is extremely
flexible and has several booleans that allow you to
manipulate the policy and run
NetworkManager_dispatcher_chronyc with the tightest access
possible.</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>
<h2>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type NetworkManager_dispatcher_chronyc_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>chronyd_var_run_t</b></p>
<p style="margin-left:11%; margin-top: 1em">/var/run/chrony(/.*)?
<br>
/var/run/chronyd(/.*)? <br>
/var/run/chrony-dhcp(/.*)? <br>
/var/run/chrony-helper(/.*)? <br>
/var/run/chronyd.pid <br>
/var/run/chronyd.sock</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
NetworkManager_dispatcher_chronyc policy is very flexible
allowing users to setup their
NetworkManager_dispatcher_chronyc 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
NetworkManager_dispatcher_chronyc:</i></p>
<p style="margin-left:11%; margin-top: 1em"><b>NetworkManager_dispatcher_chronyc_script_t</b></p>
<p style="margin-left:11%; margin-top: 1em">- Set files
with the NetworkManager_dispatcher_chronyc_script_t type, if
you want to treat the files as NetworkManager dispatcher
chronyc script data. <br>
Paths:</p>
<p style="margin-left:18%;">/etc/NetworkManager/dispatcher.d/20-chrony-dhcp,
/usr/lib/NetworkManager/dispatcher.d/20-chrony-dhcp,
/etc/NetworkManager/dispatcher.d/20-chrony-onoffline,
/usr/lib/NetworkManager/dispatcher.d/20-chrony-onoffline</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>
