<h2>NAME

</h2>
<p style="margin-left:11%; margin-top: 1em">chrome_sandbox_nacl_selinux
− Security Enhanced Linux Policy for the
chrome_sandbox_nacl processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the chrome_sandbox_nacl processes via flexible
mandatory access control.</p>
<p style="margin-left:11%; margin-top: 1em">The
chrome_sandbox_nacl processes execute with the
chrome_sandbox_nacl_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 chrome_sandbox_nacl_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
chrome_sandbox_nacl_t SELinux type can be entered via the
<b>usr_t, chrome_sandbox_nacl_exec_t, bin_t</b> file
types.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the chrome_sandbox_nacl_t domain are
the following:</p>
<p style="margin-left:11%; margin-top: 1em">All executables
with the default executable label, usually stored in
/usr/bin and /usr/sbin. /opt/.*, /usr/.*, /emul/.*,
/export(/.*)?, /ostree(/.*)?, /usr/doc(/.*)?/lib(/.*)?,
/usr/inclu.e(/.*)?, /usr/share/rpm(/.*)?,
/usr/share/doc(/.*)?/README.*,
/usr/lib/modules(/.*)/vmlinuz,
/usr/lib/modules(/.*)/initramfs.img,
/usr/lib/sysimage(/.*)?, /usr/lib/ostree-boot(/.*)?, /opt,
/usr, /emul, /opt/google/chrome[^/]*/nacl_helper_bootstrap,
/opt/google/chrome/nacl_helper_bootstrap,
/usr/lib/chromium-browser/nacl_helper_bootstrap</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
chrome_sandbox_nacl policy is very flexible allowing users
to setup their chrome_sandbox_nacl processes in as secure a
method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for chrome_sandbox_nacl:</p>
<p style="margin-left:11%; margin-top: 1em"><b>chrome_sandbox_nacl_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a chrome_sandbox_nacl_t</b> can be
used to make the process type chrome_sandbox_nacl_t
permissive. SELinux does not deny access to permissive
process types, but the AVC (SELinux denials) messages are
still generated.</p>
<h2>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type chrome_sandbox_nacl_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>chrome_sandbox_home_t</b></p>
<p style="margin-left:11%; margin-top: 1em">/home/[^/]+/.cache/chromium(/.*)?

/home/[^/]+/.config/chromium(/.*)? <br>
/home/[^/]+/.cache/google-chrome(/.*)? <br>
/home/[^/]+/.cache/google-chrome-unstable(/.*)?</p>
<p style="margin-left:11%; margin-top: 1em"><b>chrome_sandbox_tmpfs_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>−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
chrome_sandbox_nacl policy is very flexible allowing users
to setup their chrome_sandbox_nacl 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
chrome_sandbox_nacl:</i></p>
<p style="margin-left:11%; margin-top: 1em"><b>chrome_sandbox_nacl_exec_t</b></p>
<p style="margin-left:11%; margin-top: 1em">- Set files
with the chrome_sandbox_nacl_exec_t type, if you want to
transition an executable to the chrome_sandbox_nacl_t
domain. <br>
Paths:</p>
<p style="margin-left:18%;">/opt/google/chrome[^/]*/nacl_helper_bootstrap,
/opt/google/chrome/nacl_helper_bootstrap,
/usr/lib/chromium-browser/nacl_helper_bootstrap</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>system-config-selinux</b>
is a GUI tool available to customize SELinux policy
settings.</p>
