NAME

6       mozilla_plugin_selinux   -  Security  Enhanced  Linux  Policy  for  the
7       mozilla_plugin processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  mozilla_plugin_t SELinux type can be entered via the mozilla_plug‐
25       in_exec_t file type.
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

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       mozilla_plugin  policy  is  very flexible allowing users to setup their
42       mozilla_plugin processes in as secure a method as possible.
43
44       The following process types are defined for mozilla_plugin:
45
46       mozilla_plugin_t, mozilla_plugin_config_t
47
48       Note: semanage permissive -a mozilla_plugin_t can be used to  make  the
49       process  type mozilla_plugin_t permissive. SELinux does not deny access
50       to permissive process types, but the AVC (SELinux denials) messages are
51       still generated.
52
53

BOOLEANS

55       SELinux   policy  is  customizable  based  on  least  access  required.
56       mozilla_plugin policy is extremely flexible and  has  several  booleans
57       that allow you to manipulate the policy and run mozilla_plugin with the
58       tightest access possible.
59
60
61
62       If you want to allow mozilla plugin domain to bind  unreserved  tcp/udp
63       ports,  you must turn on the mozilla_plugin_bind_unreserved_ports bool‐
64       ean. Disabled by default.
65
66       setsebool -P mozilla_plugin_bind_unreserved_ports 1
67
68
69
70       If you want to allow mozilla plugin domain to connect  to  the  network
71       using  TCP,  you  must  turn  on the mozilla_plugin_can_network_connect
72       boolean. Enabled by default.
73
74       setsebool -P mozilla_plugin_can_network_connect 1
75
76
77
78       If you want to allow mozilla plugin to use Bluejeans, you must turn  on
79       the mozilla_plugin_use_bluejeans boolean. Disabled by default.
80
81       setsebool -P mozilla_plugin_use_bluejeans 1
82
83
84
85       If  you  want  to allow mozilla plugin to support GPS, you must turn on
86       the mozilla_plugin_use_gps boolean. Disabled by default.
87
88       setsebool -P mozilla_plugin_use_gps 1
89
90
91
92       If you want to allow mozilla plugin to  support  spice  protocols,  you
93       must turn on the mozilla_plugin_use_spice boolean. Disabled by default.
94
95       setsebool -P mozilla_plugin_use_spice 1
96
97
98
99       If  you  want to deny all system processes and Linux users to use blue‐
100       tooth wireless technology, you must turn on the deny_bluetooth boolean.
101       Enabled by default.
102
103       setsebool -P deny_bluetooth 1
104
105
106
107       If  you  want  to  allow  all  unconfined  executables to use libraries
108       requiring text relocation that are  not  labeled  textrel_shlib_t,  you
109       must turn on the selinuxuser_execmod boolean. Disabled by default.
110
111       setsebool -P selinuxuser_execmod 1
112
113
114
115       If  you  want  to  allow  unconfined users to transition to the Mozilla
116       plugin domain when running xulrunner plugin-container, you must turn on
117       the unconfined_mozilla_plugin_transition boolean. Disabled by default.
118
119       setsebool -P unconfined_mozilla_plugin_transition 1
120

MANAGED FILES

124       The SELinux process type mozilla_plugin_t can manage files labeled with
125       the following file types.  The paths listed are the default  paths  for
126       these  file  types.  Note the processes UID still need to have DAC per‐
127       missions.
128
129       cifs_t
130
131
132       ecryptfs_t
133
134            /home/[^/]+/.Private(/.*)?
135            /home/[^/]+/.ecryptfs(/.*)?
136
137       fusefs_t
138
139            /var/run/user/[^/]*/gvfs
140
141       nfs_t
142
143
144

FILE CONTEXTS

146       SELinux requires files to have an extended attribute to define the file
147       type.
148
149       You can see the context of a file using the -Z option to ls
150
151       Policy  governs  the  access  confined  processes  have to these files.
152       SELinux mozilla_plugin policy is very flexible allowing users to  setup
153       their mozilla_plugin processes in as secure a method as possible.
154
155       STANDARD FILE CONTEXT
156
157       SELinux  defines  the file context types for the mozilla_plugin, if you
158       wanted to store files with these types in a diffent paths, you need  to
159       execute  the  semanage  command to sepecify alternate labeling and then
160       use restorecon to put the labels on disk.
161
162       semanage fcontext -a -t mozilla_plugin_rw_t '/srv/mymozilla_plugin_con‐
163       tent(/.*)?'
164       restorecon -R -v /srv/mymozilla_plugin_content
165
166       Note:  SELinux  often  uses  regular expressions to specify labels that
167       match multiple files.
168
169       The following file types are defined for mozilla_plugin:
170
171
172
173       mozilla_plugin_config_exec_t
174
175       - Set files with the mozilla_plugin_config_exec_t type, if you want  to
176       transition an executable to the mozilla_plugin_config_t domain.
177
178
179
180       mozilla_plugin_exec_t
181
182       - Set files with the mozilla_plugin_exec_t type, if you want to transi‐
183       tion an executable to the mozilla_plugin_t domain.
184
185
186       Paths:
187            /usr/lib/xulrunner[^/]*/plugin-container,   /usr/lib/nspluginwrap‐
188            per/npviewer.bin,  /usr/bin/nspluginscan, /usr/bin/nspluginviewer,
189            /usr/libexec/WebKitPluginProcess,     /usr/lib/firefox/plugin-con‐
190            tainer
191
192
193       mozilla_plugin_rw_t
194
195       - Set files with the mozilla_plugin_rw_t type, if you want to treat the
196       files as mozilla plugin read/write content.
197
198
199
200       mozilla_plugin_tmp_t
201
202       - Set files with the mozilla_plugin_tmp_t type, if you  want  to  store
203       mozilla plugin temporary files in the /tmp directories.
204
205
206
207       mozilla_plugin_tmpfs_t
208
209       -  Set files with the mozilla_plugin_tmpfs_t type, if you want to store
210       mozilla plugin files on a tmpfs file system.
211
212
213
214       Note: File context can be temporarily modified with the chcon  command.
215       If  you want to permanently change the file context you need to use the
216       semanage fcontext command.  This will modify the SELinux labeling data‐
217       base.  You will need to use restorecon to apply the labels.
218
219

COMMANDS

221       semanage  fcontext  can also be used to manipulate default file context
222       mappings.
223
224       semanage permissive can also be used to manipulate  whether  or  not  a
225       process type is permissive.
226
227       semanage  module can also be used to enable/disable/install/remove pol‐
228       icy modules.
229
230       semanage boolean can also be used to manipulate the booleans
231
232
233       system-config-selinux is a GUI tool available to customize SELinux pol‐
234       icy settings.
