6 mozilla_plugin_selinux - Security Enhanced Linux Policy for the
7 mozilla_plugin processes
8
10 Security-Enhanced Linux secures the mozilla_plugin processes via flexi‐
11 ble mandatory access control.
12
13 The mozilla_plugin processes execute with the mozilla_plugin_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 mozilla_plugin_t
20
21
22
24 The mozilla_plugin_t SELinux type can be entered via the
25 mozilla_plugin_exec_t, user_tmp_t file types.
26
27 The default entrypoint paths for the mozilla_plugin_t domain are the
28 following:
29
30 /usr/lib/xulrunner[^/]*/plugin-container, /usr/lib/nspluginwrap‐
31 per/npviewer.bin, /usr/bin/nspluginscan, /usr/bin/nspluginviewer,
32 /usr/libexec/WebKitPluginProcess, /usr/lib/firefox/plugin-container,
33 /dev/shm/mono.*, /var/run/user/[^/]+, /tmp/.ICE-unix(/.*)?,
34 /tmp/.X11-unix(/.*)?, /dev/shm/pulse-shm.*, /tmp/.X0-lock,
35 /var/run/user, /tmp/hsperfdata_root, /var/tmp/hsperfdata_root,
36 /home/[^/]+/tmp, /home/[^/]+/.tmp, /var/run/user/[0-9]+,
37 /tmp/gconfd-[^/]+

40 SELinux defines process types (domains) for each process running on the
41 system
42
43 You can see the context of a process using the -Z option to ps
44
45 Policy governs the access confined processes have to files. SELinux
46 mozilla_plugin policy is very flexible allowing users to setup their
47 mozilla_plugin processes in as secure a method as possible.
48
49 The following process types are defined for mozilla_plugin:
50
51 mozilla_plugin_t, mozilla_plugin_config_t
52
53 Note: semanage permissive -a mozilla_plugin_t can be used to make the
54 process type mozilla_plugin_t permissive. SELinux does not deny access
55 to permissive process types, but the AVC (SELinux denials) messages are
56 still generated.
57
58
60 SELinux policy is customizable based on least access required.
61 mozilla_plugin policy is extremely flexible and has several booleans
62 that allow you to manipulate the policy and run mozilla_plugin with the
63 tightest access possible.
64
65
66
67 If you want to allow mozilla plugin domain to bind unreserved tcp/udp
68 ports, you must turn on the mozilla_plugin_bind_unreserved_ports bool‐
69 ean. Disabled by default.
70
71 setsebool -P mozilla_plugin_bind_unreserved_ports 1
72
73
74
75 If you want to allow mozilla plugin domain to connect to the network
76 using TCP, you must turn on the mozilla_plugin_can_network_connect
77 boolean. Enabled by default.
78
79 setsebool -P mozilla_plugin_can_network_connect 1
80
81
82
83 If you want to allow mozilla plugin to use Bluejeans, you must turn on
84 the mozilla_plugin_use_bluejeans boolean. Disabled by default.
85
86 setsebool -P mozilla_plugin_use_bluejeans 1
87
88
89
90 If you want to allow mozilla plugin to support GPS, you must turn on
91 the mozilla_plugin_use_gps boolean. Disabled by default.
92
93 setsebool -P mozilla_plugin_use_gps 1
94
95
96
97 If you want to allow mozilla plugin to support spice protocols, you
98 must turn on the mozilla_plugin_use_spice boolean. Disabled by default.
99
100 setsebool -P mozilla_plugin_use_spice 1
101
102
103
104 If you want to deny all system processes and Linux users to use blue‐
105 tooth wireless technology, you must turn on the deny_bluetooth boolean.
106 Enabled by default.
107
108 setsebool -P deny_bluetooth 1
109
110
111
112 If you want to allow all unconfined executables to use libraries re‐
113 quiring text relocation that are not labeled textrel_shlib_t, you must
114 turn on the selinuxuser_execmod boolean. Enabled by default.
115
116 setsebool -P selinuxuser_execmod 1
117
118
119
120 If you want to allow unconfined users to transition to the Mozilla
121 plugin domain when running xulrunner plugin-container, you must turn on
122 the unconfined_mozilla_plugin_transition boolean. Enabled by default.
123
124 setsebool -P unconfined_mozilla_plugin_transition 1
125
126
127
129 The SELinux process type mozilla_plugin_t can manage files labeled with
130 the following file types. The paths listed are the default paths for
131 these file types. Note the processes UID still need to have DAC per‐
132 missions.
133
134 cifs_t
135
136
137 ecryptfs_t
138
139 /home/[^/]+/.Private(/.*)?

171 SELinux requires files to have an extended attribute to define the file
172 type.
173
174 You can see the context of a file using the -Z option to ls
175
176 Policy governs the access confined processes have to these files.
177 SELinux mozilla_plugin policy is very flexible allowing users to setup
178 their mozilla_plugin processes in as secure a method as possible.
179
180 STANDARD FILE CONTEXT
181
182 SELinux defines the file context types for the mozilla_plugin, if you
183 wanted to store files with these types in a diffent paths, you need to
184 execute the semanage command to specify alternate labeling and then use
185 restorecon to put the labels on disk.
186
187 semanage fcontext -a -t mozilla_plugin_rw_t '/srv/mymozilla_plugin_con‐
188 tent(/.*)?'
189 restorecon -R -v /srv/mymozilla_plugin_content
190
191 Note: SELinux often uses regular expressions to specify labels that
192 match multiple files.
193
194 The following file types are defined for mozilla_plugin:
195
196
197
198 mozilla_plugin_config_exec_t
199
200 - Set files with the mozilla_plugin_config_exec_t type, if you want to
201 transition an executable to the mozilla_plugin_config_t domain.
202
203
204
205 mozilla_plugin_exec_t
206
207 - Set files with the mozilla_plugin_exec_t type, if you want to transi‐
208 tion an executable to the mozilla_plugin_t domain.
209
210
211 Paths:
212 /usr/lib/xulrunner[^/]*/plugin-container, /usr/lib/nspluginwrap‐
213 per/npviewer.bin, /usr/bin/nspluginscan, /usr/bin/nspluginviewer,
214 /usr/libexec/WebKitPluginProcess, /usr/lib/firefox/plugin-con‐
215 tainer
216
217
218 mozilla_plugin_rw_t
219
220 - Set files with the mozilla_plugin_rw_t type, if you want to treat the
221 files as mozilla plugin read/write content.
222
223
224
225 mozilla_plugin_tmp_t
226
227 - Set files with the mozilla_plugin_tmp_t type, if you want to store
228 mozilla plugin temporary files in the /tmp directories.
229
230
231
232 mozilla_plugin_tmpfs_t
233
234 - Set files with the mozilla_plugin_tmpfs_t type, if you want to store
235 mozilla plugin files on a tmpfs file system.
236
237
238
239 Note: File context can be temporarily modified with the chcon command.
240 If you want to permanently change the file context you need to use the
241 semanage fcontext command. This will modify the SELinux labeling data‐
242 base. You will need to use restorecon to apply the labels.
243
244
246 semanage fcontext can also be used to manipulate default file context
247 mappings.
248
249 semanage permissive can also be used to manipulate whether or not a
250 process type is permissive.
251
252 semanage module can also be used to enable/disable/install/remove pol‐
253 icy modules.
254
255 semanage boolean can also be used to manipulate the booleans
256
257
258 system-config-selinux is a GUI tool available to customize SELinux pol‐
259 icy settings.
