<h2>NAME
<a name="NAME"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">httpd_passwd_selinux
− Security Enhanced Linux Policy for the httpd_passwd
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the httpd_passwd processes via flexible
mandatory access control.</p>
<p style="margin-left:11%; margin-top: 1em">The
httpd_passwd processes execute with the httpd_passwd_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 httpd_passwd_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
httpd_passwd_t SELinux type can be entered via the
<b>httpd_passwd_exec_t</b> file type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the httpd_passwd_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/libexec/httpd-ssl-pass-dialog</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
httpd_passwd policy is very flexible allowing users to setup
their httpd_passwd processes in as secure a method as
possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for httpd_passwd:</p>
<p style="margin-left:11%; margin-top: 1em"><b>httpd_passwd_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a httpd_passwd_t</b> can be used to
make the process type httpd_passwd_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. httpd_passwd
policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run httpd_passwd with
the tightest access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow httpd to use opencryptoki, you must turn on the
httpd_use_opencryptoki boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
httpd_use_opencryptoki 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>
<h2>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type httpd_passwd_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>krb5_host_rcache_t</b></p>
<p style="margin-left:11%; margin-top: 1em">/var/tmp/krb5_0.rcache2

<p style="margin-left:11%; margin-top: 1em"><b>pkcs_slotd_lock_t</b></p>
<p style="margin-left:11%; margin-top: 1em">/var/lock/opencryptoki(/.*)?</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
httpd_passwd policy is very flexible allowing users to setup
their httpd_passwd 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 httpd_passwd:</i></p>
<p style="margin-left:11%; margin-top: 1em"><b>httpd_passwd_exec_t</b></p>
<p style="margin-left:11%; margin-top: 1em">- Set files
with the httpd_passwd_exec_t type, if you want to transition
an executable to the httpd_passwd_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>
