NAME

6       svirt_qemu_net_selinux   -  Security  Enhanced  Linux  Policy  for  the
7       svirt_qemu_net processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the svirt_qemu_net processes via flexi‐
11       ble mandatory access control.
12
13       The  svirt_qemu_net processes execute with the svirt_qemu_net_t SELinux
14       type. You can check if you have these processes  running  by  executing
15       the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep svirt_qemu_net_t
20

22

ENTRYPOINTS

24       The svirt_qemu_net_t SELinux type can be entered via the file_type file
25       type.
26
27       The default entrypoint paths for the svirt_qemu_net_t  domain  are  the
28       following:
29
30       all files on the system
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       svirt_qemu_net  policy  is  very flexible allowing users to setup their
40       svirt_qemu_net processes in as secure a method as possible.
41
42       The following process types are defined for svirt_qemu_net:
43
44       svirt_qemu_net_t
45
46       Note: semanage permissive -a svirt_qemu_net_t can be used to  make  the
47       process  type svirt_qemu_net_t permissive. SELinux does not deny access
48       to permissive process types, but the AVC (SELinux denials) messages are
49       still generated.

MCS Constrained

53       The  SELinux  process  type  svirt_qemu_net_t is an MCS (Multi Category
54       Security) constrained type.  Sometimes this separation is  referred  to
55       as  sVirt. These types are usually used for securing multi-tenant envi‐
56       ronments, such as virtualization, containers or  separation  of  users.
57       The  tools used to launch MCS types, pick out a different MCS label for
58       each process group.
59
60       For    example    one    process     might     be     launched     with
61       svirt_qemu_net_t:s0:c1,c2,    and   another   process   launched   with
62       svirt_qemu_net_t:s0:c3,c4. The SELinux kernel only  allows  these  pro‐
63       cesses  can  only  write to content with a matching MCS label, or a MCS
64       Label of s0. A process running with the MCS level of  s0:c1,c2  is  not
65       allowed to write to content with the MCS label of s0:c3,c4

BOOLEANS

69       SELinux   policy  is  customizable  based  on  least  access  required.
70       svirt_qemu_net policy is extremely flexible and  has  several  booleans
71       that allow you to manipulate the policy and run svirt_qemu_net with the
72       tightest access possible.
