<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
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>
<h2>BOOLEANS
<a name="BOOLEANS"></a>
</h2>
<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>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow a unconfined user to dynamically transition to a new
context using setcon, you must turn on the
unconfined_dyntrans_all boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
unconfined_dyntrans_all 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow unconfined users to transition to the Mozilla plugin
domain when running xulrunner plugin-container, you must
turn on the unconfined_mozilla_plugin_transition boolean.
Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
unconfined_mozilla_plugin_transition 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
determine whether crond can execute jobs in the user domain
as opposed to the the generic cronjob domain, you must turn
on the cron_userdomain_transition boolean. Enabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
cron_userdomain_transition 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
deny user domains applications to map a memory region as
both executable and writable, this is dangerous and the
executable should be reported in bugzilla, you must turn on
the deny_execmem boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
deny_execmem 1</b></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
