NAME

6       mplayer_selinux  -  Security Enhanced Linux Policy for the mplayer pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The  mplayer_t  SELinux type can be entered via the mplayer_exec_t file
25       type.
26
27       The default entrypoint paths for the mplayer_t domain are  the  follow‐
28       ing:
29
30       /usr/bin/vlc, /usr/bin/xine, /usr/bin/mplayer
31

PROCESS TYPES

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

BOOLEANS

53       SELinux policy is customizable based on least access required.  mplayer
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run mplayer with the tightest access possi‐
56       ble.

MANAGED FILES

203       The SELinux process type mplayer_t can manage files  labeled  with  the
204       following file types.  The paths listed are the default paths for these
205       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

263       SELinux requires files to have an extended attribute to define the file
264       type.
265
266       You can see the context of a file using the -Z option to ls
267
268       Policy  governs  the  access  confined  processes  have to these files.
269       SELinux mplayer policy is very flexible allowing users to  setup  their
270       mplayer processes in as secure a method as possible.
271
272       STANDARD FILE CONTEXT
273
274       SELinux  defines  the file context types for the mplayer, if you wanted
275       to store files with these types in a diffent paths, you need to execute
276       the  semanage  command  to  sepecify  alternate  labeling  and then use
277       restorecon to put the labels on disk.
278
279       semanage fcontext -a -t mplayer_tmpfs_t '/srv/mymplayer_content(/.*)?'
280       restorecon -R -v /srv/mymplayer_content
281
282       Note: SELinux often uses regular expressions  to  specify  labels  that
283       match multiple files.
284
285       The following file types are defined for mplayer:
286
287
288
289       mplayer_etc_t
290
291       -  Set  files with the mplayer_etc_t type, if you want to store mplayer
292       files in the /etc directories.
293
294
295
296       mplayer_exec_t
297
298       - Set files with the mplayer_exec_t type, if you want to transition  an
299       executable to the mplayer_t domain.
300
301
302       Paths:
303            /usr/bin/vlc, /usr/bin/xine, /usr/bin/mplayer
304
305
306       mplayer_home_t
307
308       -  Set files with the mplayer_home_t type, if you want to store mplayer
309       files in the users home directory.
310
311
312
313       mplayer_tmpfs_t
314
315       - Set files with the mplayer_tmpfs_t type, if you want to store mplayer
316       files on a tmpfs file system.
317
318
319
320       Note:  File context can be temporarily modified with the chcon command.
321       If you want to permanently change the file context you need to use  the
322       semanage fcontext command.  This will modify the SELinux labeling data‐
323       base.  You will need to use restorecon to apply the labels.
324
325

COMMANDS

327       semanage fcontext can also be used to manipulate default  file  context
328       mappings.
329
330       semanage  permissive  can  also  be used to manipulate whether or not a
331       process type is permissive.
332
333       semanage module can also be used to enable/disable/install/remove  pol‐
334       icy modules.
335
336       semanage boolean can also be used to manipulate the booleans
337
338
339       system-config-selinux is a GUI tool available to customize SELinux pol‐
340       icy settings.
