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
57       default.
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 users to resolve user passwd entries directly from
78       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
79       gin_nsswitch_use_ldap boolean. Disabled by default.
80
81       setsebool -P authlogin_nsswitch_use_ldap 1
82
83
84
85       If you want to allow all domains to execute in fips_mode, you must turn
86       on the fips_mode boolean. Enabled by default.
87
88       setsebool -P fips_mode 1
89
90
91
92       If you want to allow confined applications to run  with  kerberos,  you
93       must turn on the kerberos_enabled boolean. Enabled by default.
94
95       setsebool -P kerberos_enabled 1
96
97
98
99       If  you  want  to  allow  system  to run with NIS, you must turn on the
100       nis_enabled boolean. Disabled by default.
101
102       setsebool -P nis_enabled 1
103
104
105
106       If you want to allow confined applications to use nscd  shared  memory,
107       you must turn on the nscd_use_shm boolean. Enabled by default.
108
109       setsebool -P nscd_use_shm 1
110
111
112

PORT TYPES

114       SELinux defines port types to represent TCP and UDP ports.
115
116       You  can  see  the  types associated with a port by using the following
117       command:
118
119       semanage port -l
120
121
122       Policy governs the access  confined  processes  have  to  these  ports.
123       SELinux  mpd  policy is very flexible allowing users to setup their mpd
124       processes in as secure a method as possible.
125
126       The following port types are defined for mpd:
127
128
129       mpd_port_t
130
131
132
133       Default Defined Ports:
134                 tcp 6600
135

MANAGED FILES

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

FILE CONTEXTS

210       SELinux requires files to have an extended attribute to define the file
211       type.
212
213       You can see the context of a file using the -Z option to ls
214
215       Policy  governs  the  access  confined  processes  have to these files.
216       SELinux mpd policy is very flexible allowing users to setup  their  mpd
217       processes in as secure a method as possible.
218
219       EQUIVALENCE DIRECTORIES
220
221
222       mpd policy stores data with multiple different file context types under
223       the /var/lib/mpd directory.  If you would like to store the data  in  a
224       different  directory  you  can  use  the  semanage command to create an
225       equivalence mapping.  If you wanted to store this data under  the  /srv
226       dirctory you would execute the following command:
227
228       semanage fcontext -a -e /var/lib/mpd /srv/mpd
229       restorecon -R -v /srv/mpd
230
231       STANDARD FILE CONTEXT
232
233       SELinux  defines  the  file context types for the mpd, if you wanted to
234       store files with these types in a diffent paths, you  need  to  execute
235       the  semanage  command  to  sepecify  alternate  labeling  and then use
236       restorecon to put the labels on disk.
237
238       semanage fcontext -a -t mpd_var_run_t '/srv/mympd_content(/.*)?'
239       restorecon -R -v /srv/mympd_content
240
241       Note: SELinux often uses regular expressions  to  specify  labels  that
242       match multiple files.
243
244       The following file types are defined for mpd:
245
246
247
248       mpd_data_t
249
250       - Set files with the mpd_data_t type, if you want to treat the files as
251       mpd content.
252
253
254       Paths:
255            /var/lib/mpd/music(/.*)?, /var/lib/mpd/playlists(/.*)?
256
257
258       mpd_etc_t
259
260       - Set files with the mpd_etc_t type, if you want to store mpd files  in
261       the /etc directories.
262
263
264
265       mpd_exec_t
266
267       - Set files with the mpd_exec_t type, if you want to transition an exe‐
268       cutable to the mpd_t domain.
269
270
271
272       mpd_home_t
273
274       - Set files with the mpd_home_t type, if you want to store mpd files in
275       the users home directory.
276
277
278
279       mpd_initrc_exec_t
280
281       -  Set files with the mpd_initrc_exec_t type, if you want to transition
282       an executable to the mpd_initrc_t domain.
283
284
285
286       mpd_log_t
287
288       - Set files with the mpd_log_t type, if you want to treat the  data  as
289       mpd log data, usually stored under the /var/log directory.
290
291
292
293       mpd_tmp_t
294
295       - Set files with the mpd_tmp_t type, if you want to store mpd temporary
296       files in the /tmp directories.
297
298
299
300       mpd_tmpfs_t
301
302       - Set files with the mpd_tmpfs_t type, if you want to store  mpd  files
303       on a tmpfs file system.
304
305
306
307       mpd_user_data_t
308
309       -  Set  files  with  the mpd_user_data_t type, if you want to treat the
310       files as mpd user content.
311
312
313
314       mpd_var_lib_t
315
316       - Set files with the mpd_var_lib_t type, if you want to store  the  mpd
317       files under the /var/lib directory.
318
319
320
321       mpd_var_run_t
322
323       -  Set  files with the mpd_var_run_t type, if you want to store the mpd
324       files under the /run or /var/run directory.
325
326
327
328       Note: File context can be temporarily modified with the chcon  command.
329       If  you want to permanently change the file context you need to use the
330       semanage fcontext command.  This will modify the SELinux labeling data‐
331       base.  You will need to use restorecon to apply the labels.
332
333

COMMANDS

335       semanage  fcontext  can also be used to manipulate default file context
336       mappings.
337
338       semanage permissive can also be used to manipulate  whether  or  not  a
339       process type is permissive.
340
341       semanage  module can also be used to enable/disable/install/remove pol‐
342       icy modules.
343
344       semanage port can also be used to manipulate the port definitions
345
346       semanage boolean can also be used to manipulate the booleans
347
348
349       system-config-selinux is a GUI tool available to customize SELinux pol‐
350       icy settings.
