NAME

6       svirt_socket_selinux   -   Security   Enhanced  Linux  Policy  for  the
7       svirt_socket processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the svirt_socket processes via flexible
11       mandatory access control.
12
13       The  svirt_socket  processes  execute  with  the svirt_socket_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_socket_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_socket  policy  is  very  flexible  allowing users to setup their
31       svirt_socket processes in as secure a method as possible.
32
33       The following process types are defined for svirt_socket:
34
35       svirt_socket_t
36
37       Note: semanage permissive -a svirt_socket_t can be  used  to  make  the
38       process type svirt_socket_t permissive. SELinux does not deny access to
39       permissive process types, but the AVC (SELinux  denials)  messages  are
40       still generated.

BOOLEANS

44       SELinux   policy  is  customizable  based  on  least  access  required.
45       svirt_socket policy is extremely flexible and has several booleans that
46       allow you to manipulate the policy and run svirt_socket with the tight‐
47       est access possible.

49
50
51       If you want to deny any process from ptracing or  debugging  any  other
52       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
53       default.
54
55       setsebool -P deny_ptrace 1
56
57
58
59       If you want to allow any process  to  mmap  any  file  on  system  with
60       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
61       ean. Enabled by default.
62
63       setsebool -P domain_can_mmap_files 1
64
65
66
67       If you want to allow all domains write to kmsg_device, while kernel  is
68       executed  with  systemd.log_target=kmsg parameter, you must turn on the
69       domain_can_write_kmsg boolean. Disabled by default.
70
71       setsebool -P domain_can_write_kmsg 1
72
73
74
75       If you want to allow all domains to use other domains file descriptors,
76       you must turn on the domain_fd_use boolean. Enabled by default.
77
78       setsebool -P domain_fd_use 1
79
80
81
82       If  you  want to allow all domains to have the kernel load modules, you
83       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
84       default.
85
86       setsebool -P domain_kernel_load_modules 1
87
88
89
90       If you want to allow all domains to execute in fips_mode, you must turn
91       on the fips_mode boolean. Enabled by default.
92
93       setsebool -P fips_mode 1
94
95
96
97       If you want to enable reading of urandom for all domains, you must turn
98       on the global_ssp boolean. Disabled by default.
99
100       setsebool -P global_ssp 1

COMMANDS

105       semanage  fcontext  can also be used to manipulate default file context
106       mappings.
107
108       semanage permissive can also be used to manipulate  whether  or  not  a
109       process type is permissive.
110
111       semanage  module can also be used to enable/disable/install/remove pol‐
112       icy modules.
113
114       semanage boolean can also be used to manipulate the booleans
115
116
117       system-config-selinux is a GUI tool available to customize SELinux pol‐
118       icy settings.
