<p style="margin-left:11%; margin-top: 1em">l2tpd_selinux
− Security Enhanced Linux Policy for the l2tpd
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the l2tpd processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The l2tpd
processes execute with the l2tpd_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 l2tpd_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The l2tpd_t
SELinux type can be entered via the <b>l2tpd_exec_t</b> file
type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the l2tpd_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/sbin/.*l2tpd,
/usr/libexec/nm-l2tp-service</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 l2tpd
policy is very flexible allowing users to setup their l2tpd
processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for l2tpd:</p>
<p style="margin-left:11%; margin-top: 1em"><b>l2tpd_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a l2tpd_t</b> can be used to make
the process type l2tpd_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. l2tpd policy
is extremely flexible and has several booleans that allow
you to manipulate the policy and run l2tpd with the tightest
access possible.</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 confined applications to use nscd shared memory, you
must turn on the nscd_use_shm boolean. Enabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
nscd_use_shm 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
l2tpd policy is very flexible allowing users to setup their
l2tpd processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
port types are defined for l2tpd: <b><br>
l2tp_port_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Default Defined
Ports:</p>
<p style="margin-left:26%;">tcp 1701 <br>
udp 1701</p>
<h2>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type l2tpd_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>

<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
l2tpd policy is very flexible allowing users to setup their
l2tpd processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em"><b>EQUIVALENCE
DIRECTORIES</b></p>
<p style="margin-left:11%; margin-top: 1em">l2tpd policy
stores data with multiple different file context types under
the /var/run/.*l2tpd 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/run/.*l2tpd /srv/.*l2tpd <br>
restorecon -R -v /srv/.*l2tpd</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 l2tpd, 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 l2tpd_var_run_t
’/srv/myl2tpd_content(/.*)?’ <br>
restorecon -R -v /srv/myl2tpd_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">Note: File
context can be temporarily modified with the chcon command.
If you want to permanently change the file context you need
