<h2>NAME
<a name="NAME"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">svirt_qemu_net_selinux
− Security Enhanced Linux Policy for the
svirt_qemu_net processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the svirt_qemu_net processes via flexible
mandatory access control.</p>
<p style="margin-left:11%; margin-top: 1em">The
svirt_qemu_net processes execute with the svirt_qemu_net_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 svirt_qemu_net_t</b></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
svirt_qemu_net policy is very flexible allowing users to
setup their svirt_qemu_net processes in as secure a method
as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for svirt_qemu_net:</p>
<p style="margin-left:11%; margin-top: 1em"><b>svirt_qemu_net_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a svirt_qemu_net_t</b> can be used
to make the process type svirt_qemu_net_t permissive.
SELinux does not deny access to permissive process types,
but the AVC (SELinux denials) messages are still
generated.</p>
<h2>MCS Constrained
<a name="MCS Constrained"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type svirt_qemu_net_t is an MCS (Multi Category
Security) constrained type. Sometimes this separation is
referred to as sVirt. These types are usually used for
securing multi-tenant environments, such as virtualization,
containers or separation of users. The tools used to launch
MCS types, pick out a different MCS label for each process
group.</p>
<p style="margin-left:11%; margin-top: 1em">For example one
process might be launched with svirt_qemu_net_t:s0:c1,c2,
and another process launched with svirt_qemu_net_t:s0:c3,c4.
The SELinux kernel only allows these processes can only
write to content with a matching MCS label, or a MCS Label
of s0. A process running with the MCS level of s0:c1,c2 is
not allowed to write to content with the MCS label of
s0:c3,c4</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.
svirt_qemu_net policy is extremely flexible and has several
booleans that allow you to manipulate the policy and run
svirt_qemu_net 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.
Disabled 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 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
allow sandbox containers to send audit messages, you must
turn on the virt_sandbox_use_audit boolean. Enabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
virt_sandbox_use_audit 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow sandbox containers to use netlink system calls, you
must turn on the virt_sandbox_use_netlink boolean. Disabled
by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
virt_sandbox_use_netlink 1</b></p>
<h2>MANAGED FILES

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>
