<p style="margin-left:11%; margin-top: 1em">unconfined_r
− <b>Unconfined user role</b> - Security Enhanced
Linux Policy</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux
supports Roles Based Access Control (RBAC), some Linux roles
are login roles, while other roles need to be transition
into.</p>
<p style="margin-left:11%; margin-top: 1em"><i>Note:</i>
Examples in this man page will use the <b>staff_u</b>
SELinux user.</p>
<p style="margin-left:11%; margin-top: 1em">Non login roles
are usually used for administrative tasks. For example,
tasks that require root privileges. Roles control which
types a user can run processes with. Roles often have
default types assigned to them.</p>
<p style="margin-left:11%; margin-top: 1em">The default
type for the unconfined_r role is unconfined_t.</p>
<p style="margin-left:11%; margin-top: 1em">The
<b>newrole</b> program to transition directly to this
role.</p>
<p style="margin-left:11%; margin-top: 1em"><b>newrole -r
unconfined_r -t unconfined_t</b></p>
<p style="margin-left:11%; margin-top: 1em"><b>sudo</b> is
the preferred method to do transition from one role to
another. You setup sudo to transition to unconfined_r by
adding a similar line to the /etc/sudoers file.</p>
<p style="margin-left:11%; margin-top: 1em">USERNAME
ALL=(ALL) ROLE=unconfined_r TYPE=unconfined_t COMMAND</p>
<p style="margin-left:11%; margin-top: 1em">sudo will run
COMMAND as staff_u:unconfined_r:unconfined_t:LEVEL</p>
<p style="margin-left:11%; margin-top: 1em">When using a a
non login role, you need to setup SELinux so that your
SELinux user can reach unconfined_r role.</p>
<p style="margin-left:11%; margin-top: 1em">Execute the
following to see all of the assigned SELinux roles:</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
user -l</b></p>
<p style="margin-left:11%; margin-top: 1em">You need to add
unconfined_r to the staff_u user. You could setup the
staff_u user to be able to use the unconfined_r role with a
command like:</p>
<p style="margin-left:11%; margin-top: 1em"><b>$ semanage
user -m -R ’staff_r system_r unconfined_r’
staff_u</b></p>

<p style="margin-left:11%; margin-top: 1em">SELinux policy
is customizable based on least access required. unconfined
policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run unconfined with
the tightest access possible.</p>
