NAME

6       virt_bridgehelper_selinux  -  Security  Enhanced  Linux  Policy for the
7       virt_bridgehelper processes
8

DESCRIPTION

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

22

ENTRYPOINTS

24       The   virt_bridgehelper_t   SELinux   type   can  be  entered  via  the
25       virt_bridgehelper_exec_t file type.
26
27       The default entrypoint paths for the virt_bridgehelper_t domain are the
28       following:
29
30       /usr/libexec/qemu-bridge-helper
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       virt_bridgehelper policy is very flexible allowing users to setup their
40       virt_bridgehelper processes in as secure a method as possible.
41
42       The following process types are defined for virt_bridgehelper:
43
44       virt_bridgehelper_t
45
46       Note: semanage permissive -a virt_bridgehelper_t can be  used  to  make
47       the  process type virt_bridgehelper_t permissive. SELinux does not deny
48       access to permissive process types, but the AVC (SELinux denials)  mes‐
49       sages are still generated.

51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       virt_bridgehelper policy is extremely flexible and has several booleans
55       that  allow you to manipulate the policy and run virt_bridgehelper with
56       the tightest access possible.
57
58
59
60       If you want to allow all domains to execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1

MANAGED FILES

68       The  SELinux  process type virt_bridgehelper_t can manage files labeled
69       with the following file types.  The paths listed are the default  paths
70       for  these  file  types.  Note the processes UID still need to have DAC
71       permissions.
72
73       svirt_home_t
74
75            /home/[^/]+/.libvirt/qemu(/.*)?
76            /home/[^/]+/.cache/libvirt/qemu(/.*)?
77            /home/[^/]+/.config/libvirt/qemu(/.*)?
78            /home/[^/]+/.local/share/libvirt/boot(/.*)?
79            /home/[^/]+/.local/share/libvirt/images(/.*)?
80            /home/[^/]+/.local/share/gnome-boxes/images(/.*)?

FILE CONTEXTS

84       SELinux requires files to have an extended attribute to define the file
85       type.
86
87       You can see the context of a file using the -Z option to ls
88
89       Policy  governs  the  access  confined  processes  have to these files.
90       SELinux virt_bridgehelper policy is very  flexible  allowing  users  to
91       setup their virt_bridgehelper processes in as secure a method as possi‐
92       ble.
93
94       STANDARD FILE CONTEXT
95
96       SELinux defines the file context types for  the  virt_bridgehelper,  if
97       you  wanted  to  store files with these types in a different paths, you
98       need to execute the semanage command to specify alternate labeling  and
99       then use restorecon to put the labels on disk.
100
101       semanage  fcontext  -a  -t  virt_bridgehelper_exec_t '/srv/virt_bridge‐
102       helper/content(/.*)?'
103       restorecon -R -v /srv/myvirt_bridgehelper_content
104
105       Note: SELinux often uses regular expressions  to  specify  labels  that
106       match multiple files.
107
108       The following file types are defined for virt_bridgehelper:
109
110
111
112       virt_bridgehelper_exec_t
113
114       -  Set  files  with  the  virt_bridgehelper_exec_t type, if you want to
115       transition an executable to the virt_bridgehelper_t domain.
116
117
118
119       Note: File context can be temporarily modified with the chcon  command.
120       If  you want to permanently change the file context you need to use the
121       semanage fcontext command.  This will modify the SELinux labeling data‐
122       base.  You will need to use restorecon to apply the labels.

124

COMMANDS

126       semanage  fcontext  can also be used to manipulate default file context
127       mappings.
128
129       semanage permissive can also be used to manipulate  whether  or  not  a
130       process type is permissive.
131
132       semanage  module can also be used to enable/disable/install/remove pol‐
133       icy modules.
134
135       semanage boolean can also be used to manipulate the booleans
136
137
138       system-config-selinux is a GUI tool available to customize SELinux pol‐
139       icy settings.
