6 virt_bridgehelper_selinux - Security Enhanced Linux Policy for the
7 virt_bridgehelper processes
8
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
21
22
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
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.
50
51
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
64
65
66
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(/.*)?
81
82
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.
123
124
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.
