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
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-[^/]+

PROCESS TYPES

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.

BOOLEANS

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.

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.

105       tooth wireless technology, you must turn on the deny_bluetooth boolean.
106       Disabled by default.
107
108       setsebool -P deny_bluetooth 1
109

119       If  you  want  to allow all unconfined executables to use libraries re‐
120       quiring text relocation that are not labeled textrel_shlib_t, you  must
121       turn on the selinuxuser_execmod boolean. Enabled by default.

MANAGED FILES

143       The SELinux process type mozilla_plugin_t can manage files labeled with
144       the  following  file types.  The paths listed are the default paths for
145       these file types.  Note the processes UID still need to have  DAC  per‐
146       missions.

150

FILE CONTEXTS

185       SELinux requires files to have an extended attribute to define the file
186       type.
187
188       You can see the context of a file using the -Z option to ls
189
190       Policy governs the access  confined  processes  have  to  these  files.
191       SELinux  mozilla_plugin policy is very flexible allowing users to setup
192       their mozilla_plugin processes in as secure a method as possible.
193
194       STANDARD FILE CONTEXT
195
196       SELinux defines the file context types for the mozilla_plugin,  if  you
197       wanted  to  store files with these types in a different paths, you need
198       to execute the semanage command to specify alternate labeling and  then
199       use restorecon to put the labels on disk.
200
201       semanage fcontext -a -t mozilla_plugin_exec_t '/srv/mozilla_plugin/con‐
202       tent(/.*)?'
203       restorecon -R -v /srv/mymozilla_plugin_content
204
205       Note: SELinux often uses regular expressions  to  specify  labels  that
206       match multiple files.
207
208       The following file types are defined for mozilla_plugin:
209
210
211
212       mozilla_plugin_config_exec_t
213
214       -  Set files with the mozilla_plugin_config_exec_t type, if you want to
215       transition an executable to the mozilla_plugin_config_t domain.
216
217
218
219       mozilla_plugin_exec_t
220
221       - Set files with the mozilla_plugin_exec_t type, if you want to transi‐
222       tion an executable to the mozilla_plugin_t domain.
223
224
225       Paths:
226            /usr/lib/xulrunner[^/]*/plugin-container,   /usr/lib/nspluginwrap‐
227            per/npviewer.bin, /usr/bin/nspluginscan,  /usr/bin/nspluginviewer,
228            /usr/libexec/WebKitPluginProcess,     /usr/lib/firefox/plugin-con‐
229            tainer
230
231
232       mozilla_plugin_rw_t
233
234       - Set files with the mozilla_plugin_rw_t type, if you want to treat the
235       files as mozilla plugin read/write content.
236
237
238
239       mozilla_plugin_tmp_t
240
241       -  Set  files  with the mozilla_plugin_tmp_t type, if you want to store
242       mozilla plugin temporary files in the /tmp directories.
243
244
245
246       mozilla_plugin_tmpfs_t
247
248       - Set files with the mozilla_plugin_tmpfs_t type, if you want to  store
249       mozilla plugin files on a tmpfs file system.
250
251
252
253       Note:  File context can be temporarily modified with the chcon command.
254       If you want to permanently change the file context you need to use  the
255       semanage fcontext command.  This will modify the SELinux labeling data‐
256       base.  You will need to use restorecon to apply the labels.
257
258

COMMANDS

260       semanage fcontext can also be used to manipulate default  file  context
261       mappings.
262
263       semanage  permissive  can  also  be used to manipulate whether or not a
264       process type is permissive.
265
266       semanage module can also be used to enable/disable/install/remove  pol‐
267       icy modules.
268
269       semanage boolean can also be used to manipulate the booleans
270
271
272       system-config-selinux is a GUI tool available to customize SELinux pol‐
273       icy settings.
