NAME

6       svirt_kvm_net_selinux   -   Security  Enhanced  Linux  Policy  for  the
7       svirt_kvm_net processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the svirt_kvm_net processes via  flexi‐
11       ble mandatory access control.
12
13       The  svirt_kvm_net  processes  execute with the svirt_kvm_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_kvm_net_t

PROCESS TYPES

24       SELinux defines process types (domains) for each process running on the
25       system
26
27       You can see the context of a process using the -Z option to ps
28
29       Policy governs the access confined processes have  to  files.   SELinux
30       svirt_kvm_net  policy  is  very  flexible allowing users to setup their
31       svirt_kvm_net processes in as secure a method as possible.
32
33       The following process types are defined for svirt_kvm_net:
34
35       svirt_kvm_net_t
36
37       Note: semanage permissive -a svirt_kvm_net_t can be used  to  make  the
38       process  type  svirt_kvm_net_t permissive. SELinux does not deny access
39       to permissive process types, but the AVC (SELinux denials) messages are
40       still generated.

MCS Constrained

44       The  SELinux process type svirt_kvm_net_t is an MCS (Multi Category Se‐
45       curity) constrained type.  Sometimes this separation is referred to  as
46       sVirt.  These types are usually used for securing multi-tenant environ‐
47       ments, such as virtualization, containers or separation of users.   The
48       tools used to launch MCS types, pick out a different MCS label for each
49       process group.
50
51       For    example    one    process     might     be     launched     with
52       svirt_kvm_net_t:s0:c1,c2,    and    another   process   launched   with
53       svirt_kvm_net_t:s0:c3,c4. The SELinux kernel  only  allows  these  pro‐
54       cesses  can  only  write to content with a matching MCS label, or a MCS
55       Label of s0. A process running with the MCS level of  s0:c1,c2  is  not
56       allowed to write to content with the MCS label of s0:c3,c4

BOOLEANS

60       SELinux   policy  is  customizable  based  on  least  access  required.
61       svirt_kvm_net policy is extremely flexible  and  has  several  booleans
62       that  allow you to manipulate the policy and run svirt_kvm_net with the
63       tightest access possible.
64
65
66
67       If you want to deny any process from ptracing or  debugging  any  other
68       processes,  you  must  turn on the deny_ptrace boolean. Disabled by de‐
69       fault.
70
71       setsebool -P deny_ptrace 1
72
73
74
75       If you want to allow system to run with  NIS,  you  must  turn  on  the
76       nis_enabled boolean. Disabled by default.
77
78       setsebool -P nis_enabled 1
79
80
81
82       If  you  want  to  allow sandbox containers to send audit messages, you
83       must turn on the virt_sandbox_use_audit boolean. Enabled by default.
84
85       setsebool -P virt_sandbox_use_audit 1
86
87
88
89       If you want to allow sandbox containers to use  netlink  system  calls,
90       you  must turn on the virt_sandbox_use_netlink boolean. Disabled by de‐
91       fault.
92
93       setsebool -P virt_sandbox_use_netlink 1

MANAGED FILES

98       The SELinux process type svirt_kvm_net_t can manage files labeled  with
99       the  following  file types.  The paths listed are the default paths for
100       these file types.  Note the processes UID still need to have  DAC  per‐
101       missions.
