NAME

6       nsplugin_selinux - Security Enhanced Linux Policy for the nsplugin pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  nsplugin  processes  via  flexible
11       mandatory access control.
12
13       The  nsplugin  processes  execute with the nsplugin_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep nsplugin_t
20
21
22

ENTRYPOINTS

24       The nsplugin_t SELinux type can be entered via the nsplugin_exec_t file
25       type.
26
27       The default entrypoint paths for the nsplugin_t domain are the  follow‐
28       ing:
29
30       /usr/lib(64)?/nspluginwrapper/npviewer.bin,      /usr/bin/nspluginscan,
31       /usr/bin/nspluginviewer
32

PROCESS TYPES

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

BOOLEANS

54       SELinux policy is customizable based on least access required.   nsplu‐
55       gin  policy  is  extremely flexible and has several booleans that allow
56       you to manipulate the policy and run nsplugin with the tightest  access
57       possible.

FILE CONTEXTS

281       SELinux requires files to have an extended attribute to define the file
282       type.
283
284       You can see the context of a file using the -Z option to ls
285
286       Policy governs the access  confined  processes  have  to  these  files.
287       SELinux  nsplugin policy is very flexible allowing users to setup their
288       nsplugin processes in as secure a method as possible.
289
290       STANDARD FILE CONTEXT
291
292       SELinux defines the file context types for the nsplugin, if you  wanted
293       to store files with these types in a diffent paths, you need to execute
294       the semanage command  to  sepecify  alternate  labeling  and  then  use
295       restorecon to put the labels on disk.
296
297       semanage fcontext -a -t nsplugin_tmp_t '/srv/mynsplugin_content(/.*)?'
298       restorecon -R -v /srv/mynsplugin_content
299
300       Note:  SELinux  often  uses  regular expressions to specify labels that
301       match multiple files.
302
303       The following file types are defined for nsplugin:
304
305
306
307       nsplugin_config_exec_t
308
309       - Set files with the nsplugin_config_exec_t type, if you want to  tran‐
310       sition an executable to the nsplugin_config_t domain.
311
312
313
314       nsplugin_exec_t
315
316       - Set files with the nsplugin_exec_t type, if you want to transition an
317       executable to the nsplugin_t domain.
318
319
320       Paths:
321            /usr/lib(64)?/nspluginwrapper/npviewer.bin, /usr/bin/nspluginscan,
322            /usr/bin/nspluginviewer
323
324
325       nsplugin_home_t
326
327       -  Set files with the nsplugin_home_t type, if you want to store nsplu‐
328       gin files in the users home directory.
329
330
331       Paths:
332            /home/[^/]*/.adobe(/.*)?,           /home/[^/]*/.macromedia(/.*)?,
333            /home/[^/]*/.gcjwebplugin(/.*)?, /home/[^/]*/.icedteaplugin(/.*)?,
334            /home/staff/.adobe(/.*)?,           /home/staff/.macromedia(/.*)?,
335            /home/staff/.gcjwebplugin(/.*)?, /home/staff/.icedteaplugin(/.*)?
336
337
338       nsplugin_rw_t
339
340       - Set files with the nsplugin_rw_t type, if you want to treat the files
341       as nsplugin read/write content.
342
343
344
345       nsplugin_tmp_t
346
347       - Set files with the nsplugin_tmp_t type, if you want to store nsplugin
348       temporary files in the /tmp directories.
349
350
351
352       Note:  File context can be temporarily modified with the chcon command.
353       If you want to permanently change the file context you need to use  the
354       semanage fcontext command.  This will modify the SELinux labeling data‐
355       base.  You will need to use restorecon to apply the labels.
356
357

COMMANDS

359       semanage fcontext can also be used to manipulate default  file  context
360       mappings.
361
362       semanage  permissive  can  also  be used to manipulate whether or not a
363       process type is permissive.
364
365       semanage module can also be used to enable/disable/install/remove  pol‐
366       icy modules.
367
368       semanage boolean can also be used to manipulate the booleans
369
370
371       system-config-selinux is a GUI tool available to customize SELinux pol‐
372       icy settings.
