NAME

6       mpd_selinux - Security Enhanced Linux Policy for the mpd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The mpd_t SELinux type can be entered via the mpd_exec_t file type.
24
25       The default entrypoint paths for the mpd_t domain are the following:
26
27       /usr/bin/mpd
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       mpd policy is very flexible allowing users to setup their mpd processes
37       in as secure a method as possible.
38
39       The following process types are defined for mpd:
40
41       mpd_t
42
43       Note: semanage permissive -a mpd_t can be used to make the process type
44       mpd_t permissive. SELinux does not deny access  to  permissive  process
45       types, but the AVC (SELinux denials) messages are still generated.
46
47

BOOLEANS

49       SELinux  policy  is  customizable  based on least access required.  mpd
50       policy is extremely flexible and has several booleans that allow you to
51       manipulate the policy and run mpd with the tightest access possible.
52
53
54
55       If  you  want  to determine whether mpd can traverse user home directo‐
56       ries, you must turn on the mpd_enable_homedirs boolean. Disabled by de‐
57       fault.
58
59       setsebool -P mpd_enable_homedirs 1
60
61
62
63       If  you  want  to  determine whether mpd can use cifs file systems, you
64       must turn on the mpd_use_cifs boolean. Disabled by default.
65
66       setsebool -P mpd_use_cifs 1
67
68
69
70       If you want to determine whether mpd can use nfs file systems, you must
71       turn on the mpd_use_nfs boolean. Disabled by default.
72
73       setsebool -P mpd_use_nfs 1
74
75
76
77       If you want to allow all domains to execute in fips_mode, you must turn
78       on the fips_mode boolean. Enabled by default.
79
80       setsebool -P fips_mode 1
81
82
83

PORT TYPES

85       SELinux defines port types to represent TCP and UDP ports.
86
87       You can see the types associated with a port  by  using  the  following
88       command:
89
90       semanage port -l
91
92
93       Policy  governs  the  access  confined  processes  have to these ports.
94       SELinux mpd policy is very flexible allowing users to setup  their  mpd
95       processes in as secure a method as possible.
96
97       The following port types are defined for mpd:
98
99
100       mpd_port_t
101
102
103
104       Default Defined Ports:
105                 tcp 6600
106

MANAGED FILES

108       The  SELinux  process type mpd_t can manage files labeled with the fol‐
109       lowing file types.  The paths listed are the default  paths  for  these
110       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

193       SELinux requires files to have an extended attribute to define the file
194       type.
195
196       You can see the context of a file using the -Z option to ls
197
198       Policy governs the access  confined  processes  have  to  these  files.
199       SELinux  mpd  policy is very flexible allowing users to setup their mpd
200       processes in as secure a method as possible.
201
202       EQUIVALENCE DIRECTORIES
203
204
205       mpd policy stores data with multiple different file context types under
206       the  /var/lib/mpd  directory.  If you would like to store the data in a
207       different directory you can use  the  semanage  command  to  create  an
208       equivalence  mapping.   If you wanted to store this data under the /srv
209       directory you would execute the following command:
210
211       semanage fcontext -a -e /var/lib/mpd /srv/mpd
212       restorecon -R -v /srv/mpd
213
214       STANDARD FILE CONTEXT
215
216       SELinux defines the file context types for the mpd, if  you  wanted  to
217       store  files  with  these types in a diffent paths, you need to execute
218       the semanage command to specify alternate labeling  and  then  use  re‐
219       storecon to put the labels on disk.
220
221       semanage fcontext -a -t mpd_var_run_t '/srv/mympd_content(/.*)?'
222       restorecon -R -v /srv/mympd_content
223
224       Note:  SELinux  often  uses  regular expressions to specify labels that
225       match multiple files.
226
227       The following file types are defined for mpd:
228
229
230
231       mpd_data_t
232
233       - Set files with the mpd_data_t type, if you want to treat the files as
234       mpd content.
235
236
237       Paths:
238            /var/lib/mpd/music(/.*)?, /var/lib/mpd/playlists(/.*)?
239
240
241       mpd_etc_t
242
243       -  Set files with the mpd_etc_t type, if you want to store mpd files in
244       the /etc directories.
245
246
247
248       mpd_exec_t
249
250       - Set files with the mpd_exec_t type, if you want to transition an exe‐
251       cutable to the mpd_t domain.
252
253
254
255       mpd_home_t
256
257       - Set files with the mpd_home_t type, if you want to store mpd files in
258       the users home directory.
259
260
261
262       mpd_initrc_exec_t
263
264       - Set files with the mpd_initrc_exec_t type, if you want to  transition
265       an executable to the mpd_initrc_t domain.
266
267
268
269       mpd_log_t
270
271       -  Set  files with the mpd_log_t type, if you want to treat the data as
272       mpd log data, usually stored under the /var/log directory.
273
274
275
276       mpd_tmp_t
277
278       - Set files with the mpd_tmp_t type, if you want to store mpd temporary
279       files in the /tmp directories.
280
281
282
283       mpd_tmpfs_t
284
285       -  Set  files with the mpd_tmpfs_t type, if you want to store mpd files
286       on a tmpfs file system.
287
288
289
290       mpd_user_data_t
291
292       - Set files with the mpd_user_data_t type, if you  want  to  treat  the
293       files as mpd user content.
294
295
296
297       mpd_var_lib_t
298
299       -  Set  files with the mpd_var_lib_t type, if you want to store the mpd
300       files under the /var/lib directory.
301
302
303
304       mpd_var_run_t
305
306       - Set files with the mpd_var_run_t type, if you want to store  the  mpd
307       files under the /run or /var/run directory.
308
309
310
311       Note:  File context can be temporarily modified with the chcon command.
312       If you want to permanently change the file context you need to use  the
313       semanage fcontext command.  This will modify the SELinux labeling data‐
314       base.  You will need to use restorecon to apply the labels.
315
316

COMMANDS

318       semanage fcontext can also be used to manipulate default  file  context
319       mappings.
320
321       semanage  permissive  can  also  be used to manipulate whether or not a
322       process type is permissive.
323
324       semanage module can also be used to enable/disable/install/remove  pol‐
325       icy modules.
326
327       semanage port can also be used to manipulate the port definitions
328
329       semanage boolean can also be used to manipulate the booleans
330
331
332       system-config-selinux is a GUI tool available to customize SELinux pol‐
333       icy settings.
