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 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
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
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.

293 SELinux requires files to have an extended attribute to define the file
294 type.
295
296 You can see the context of a file using the -Z option to ls
297
298 Policy governs the access confined processes have to these files.
299 SELinux mozilla_plugin policy is very flexible allowing users to setup
300 their mozilla_plugin processes in as secure a method as possible.
301
302 STANDARD FILE CONTEXT
303
304 SELinux defines the file context types for the mozilla_plugin, if you
305 wanted to store files with these types in a diffent paths, you need to
306 execute the semanage command to sepecify alternate labeling and then
307 use restorecon to put the labels on disk.
308
309 semanage fcontext -a -t mozilla_plugin_rw_t '/srv/mymozilla_plugin_con‐
310 tent(/.*)?'
311 restorecon -R -v /srv/mymozilla_plugin_content
312
313 Note: SELinux often uses regular expressions to specify labels that
314 match multiple files.
315
316 The following file types are defined for mozilla_plugin:
317
318
319
320 mozilla_plugin_config_exec_t
321
322 - Set files with the mozilla_plugin_config_exec_t type, if you want to
323 transition an executable to the mozilla_plugin_config_t domain.
324
325
326
327 mozilla_plugin_exec_t
328
329 - Set files with the mozilla_plugin_exec_t type, if you want to transi‐
330 tion an executable to the mozilla_plugin_t domain.
331
332
333 Paths:
334 /usr/lib/xulrunner[^/]*/plugin-container, /usr/lib/nspluginwrap‐
335 per/npviewer.bin, /usr/bin/nspluginscan, /usr/bin/nspluginviewer,
336 /usr/libexec/WebKitPluginProcess, /usr/lib/firefox/plugin-con‐
337 tainer
338
339
340 mozilla_plugin_rw_t
341
342 - Set files with the mozilla_plugin_rw_t type, if you want to treat the
343 files as mozilla plugin read/write content.
344
345
346
347 mozilla_plugin_tmp_t
348
349 - Set files with the mozilla_plugin_tmp_t type, if you want to store
350 mozilla plugin temporary files in the /tmp directories.
351
352
353
354 mozilla_plugin_tmpfs_t
355
356 - Set files with the mozilla_plugin_tmpfs_t type, if you want to store
357 mozilla plugin files on a tmpfs file system.
358
359
360
361 Note: File context can be temporarily modified with the chcon command.
362 If you want to permanently change the file context you need to use the
363 semanage fcontext command. This will modify the SELinux labeling data‐
364 base. You will need to use restorecon to apply the labels.
365
366
368 semanage fcontext can also be used to manipulate default file context
369 mappings.
370
371 semanage permissive can also be used to manipulate whether or not a
372 process type is permissive.
373
374 semanage module can also be used to enable/disable/install/remove pol‐
375 icy modules.
376
377 semanage boolean can also be used to manipulate the booleans
378
379
380 system-config-selinux is a GUI tool available to customize SELinux pol‐
381 icy settings.
