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

59
60 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.

142 If you want to support X userspace object manager, you must turn on the
143 xserver_object_manager boolean. Disabled by default.
144
145 setsebool -P xserver_object_manager 1
146
147
148
150 The SELinux process type mplayer_t can manage files labeled with the
151 following file types. The paths listed are the default paths for these
152 file types. Note the processes UID still need to have DAC permissions.

208 SELinux requires files to have an extended attribute to define the file
209 type.
210
211 You can see the context of a file using the -Z option to ls
212
213 Policy governs the access confined processes have to these files.
214 SELinux mplayer policy is very flexible allowing users to setup their
215 mplayer processes in as secure a method as possible.
216
217 STANDARD FILE CONTEXT
218
219 SELinux defines the file context types for the mplayer, if you wanted
220 to store files with these types in a diffent paths, you need to execute
221 the semanage command to sepecify alternate labeling and then use
222 restorecon to put the labels on disk.
223
224 semanage fcontext -a -t mplayer_tmpfs_t '/srv/mymplayer_content(/.*)?'
225 restorecon -R -v /srv/mymplayer_content
226
227 Note: SELinux often uses regular expressions to specify labels that
228 match multiple files.
229
230 The following file types are defined for mplayer:
231
232
233
234 mplayer_etc_t
235
236 - Set files with the mplayer_etc_t type, if you want to store mplayer
237 files in the /etc directories.
238
239
240
241 mplayer_exec_t
242
243 - Set files with the mplayer_exec_t type, if you want to transition an
244 executable to the mplayer_t domain.
245
246
247 Paths:
248 /usr/bin/vlc, /usr/bin/xine, /usr/bin/mplayer
249
250
251 mplayer_home_t
252
253 - Set files with the mplayer_home_t type, if you want to store mplayer
254 files in the users home directory.
255
256
257 Paths:
258 /home/[^/]*/.mplayer(/.*)?, /home/staff/.mplayer(/.*)?
259
260
261 mplayer_tmpfs_t
262
263 - Set files with the mplayer_tmpfs_t type, if you want to store mplayer
264 files on a tmpfs file system.
265
266
267
268 Note: File context can be temporarily modified with the chcon command.
269 If you want to permanently change the file context you need to use the
270 semanage fcontext command. This will modify the SELinux labeling data‐
271 base. You will need to use restorecon to apply the labels.
272
273
275 semanage fcontext can also be used to manipulate default file context
276 mappings.
277
278 semanage permissive can also be used to manipulate whether or not a
279 process type is permissive.
280
281 semanage module can also be used to enable/disable/install/remove pol‐
282 icy modules.
283
284 semanage boolean can also be used to manipulate the booleans
285
286
287 system-config-selinux is a GUI tool available to customize SELinux pol‐
288 icy settings.
