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

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



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

<p style="margin-left:11%; margin-top: 1em">The iceauth
processes execute with the iceauth_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 iceauth_t</b></p>

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


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

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


<p style="margin-left:11%; margin-top: 1em">/usr/bin/iceauth,
/usr/X11R6/bin/iceauth</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 iceauth
policy is very flexible allowing users to setup their
iceauth processes in as secure a method as possible.</p>

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


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

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

<p style="margin-left:11%; margin-top: 1em">If you want to
deny any process from ptracing or debugging any other
processes, you must turn on the deny_ptrace boolean. Enabled
by default.</p>

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

<p style="margin-left:11%; margin-top: 1em">If you want to
allow any process to mmap any file on system with attribute
file_type, you must turn on the domain_can_mmap_files
boolean. Enabled by default.</p>

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

<p style="margin-left:11%; margin-top: 1em">If you want to
allow all domains write to kmsg_device, while kernel is
executed with systemd.log_target=kmsg parameter, you must
turn on the domain_can_write_kmsg boolean. Disabled by
default.</p>

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

<p style="margin-left:11%; margin-top: 1em">If you want to
allow all domains to use other domains file descriptors, you
must turn on the domain_fd_use boolean. Enabled by
default.</p>

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

<p style="margin-left:11%; margin-top: 1em">If you want to
allow all domains to have the kernel load modules, you must
turn on the domain_kernel_load_modules boolean. Disabled by
default.</p>

<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
domain_kernel_load_modules 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
enable reading of urandom for all domains, you must turn on
the global_ssp boolean. Disabled by default.</p>

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

<p style="margin-left:11%; margin-top: 1em">If you want to
support ecryptfs home directories, you must turn on the
use_ecryptfs_home_dirs boolean. Disabled by default.</p>

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

<p style="margin-left:11%; margin-top: 1em">If you want to

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

<p style="margin-left:11%; margin-top: 1em">If you want to
support NFS home directories, you must turn on the
use_nfs_home_dirs boolean. Disabled by default.</p>

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

<p style="margin-left:11%; margin-top: 1em">If you want to

<h2>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>


<p style="margin-left:11%; margin-top: 1em">The SELinux
process type iceauth_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>cifs_t</b></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>&minus;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
iceauth policy is very flexible allowing users to setup
their iceauth processes in as secure a method as
possible.</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 iceauth, if you wanted to
store files with these types in a diffent paths, you need to
execute the semanage command to sepecify 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 iceauth_home_t
&rsquo;/srv/myiceauth_content(/.*)?&rsquo; <br>
restorecon -R -v /srv/myiceauth_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
following file types are defined for iceauth:</i></p>


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

<p style="margin-left:11%; margin-top: 1em">- Set files
with the iceauth_exec_t type, if you want to transition an
executable to the iceauth_t domain. <br>
Paths:</p>

<p style="margin-left:18%;">/usr/bin/iceauth,
/usr/X11R6/bin/iceauth</p>


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

<p style="margin-left:11%; margin-top: 1em">- Set files
with the iceauth_home_t type, if you want to store iceauth
files in the users home directory. <br>
Paths:</p>

<p style="margin-left:18%;">/root/.DCOP.*,
/root/.ICEauthority.*, /home/[^/]+/.DCOP.*,
/home/[^/]+/.ICEauthority.*</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>
