− Security Enhanced Linux Policy for the rpm
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the rpm processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The rpm
processes execute with the rpm_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 rpm_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The rpm_t
SELinux type can be entered via the <b>rpm_script_exec_t,
rpm_exec_t, debuginfo_exec_t</b> file types.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the rpm_t domain are the following:</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 rpm
policy is very flexible allowing users to setup their rpm
processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for rpm:</p>
<p style="margin-left:11%; margin-top: 1em"><b>rpm_t,
rpmdb_t, rpm_script_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a rpm_t</b> can be used to make the
process type rpm_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. rpm policy
is extremely flexible and has several booleans that allow
you to manipulate the policy and run rpm with the tightest
access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
control the ability to mmap a low area of the address space,
as configured by /proc/sys/vm/mmap_min_addr, you must turn
on the mmap_low_allowed boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
mmap_low_allowed 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>
<p style="margin-left:11%; margin-top: 1em">If you want to
disable kernel module loading, you must turn on the
secure_mode_insmod boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
secure_mode_insmod 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow unconfined executables to make their heap memory
executable. Doing this is a really bad idea. Probably
indicates a badly coded executable, but could indicate an
attack. This executable should be reported in bugzilla, you
must turn on the selinuxuser_execheap boolean. Disabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
selinuxuser_execheap 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow unconfined executables to make their stack executable.
This should never, ever be necessary. Probably indicates a
badly coded executable, but could indicate an attack. This
executable should be reported in bugzilla, you must turn on
the selinuxuser_execstack boolean. Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
selinuxuser_execstack 1</b></p>
<h2>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type rpm_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>file_type</b></p>

<td width="7%"></td>

<p>all files on the system</p></td></tr>
</table>
<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
rpm policy is very flexible allowing users to setup their
rpm 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">rpm policy
stores data with multiple different file context types under
the /var/lib/rpm 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/lib/rpm /srv/rpm <br>
restorecon -R -v /srv/rpm</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 rpm, 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 rpm_script_tmpfs_t
’/srv/myrpm_content(/.*)?’ <br>
restorecon -R -v /srv/myrpm_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"><b>rpm_exec_t</b></p>
