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

PORT TYPES

216       SELinux defines port types to represent TCP and UDP ports.
217
218       You  can  see  the  types associated with a port by using the following
219       command:
220
221       semanage port -l
222
223
224       Policy governs the access  confined  processes  have  to  these  ports.
225       SELinux  mpd  policy is very flexible allowing users to setup their mpd
226       processes in as secure a method as possible.
227
228       The following port types are defined for mpd:
229
230
231       mpd_port_t
232
233
234
235       Default Defined Ports:
236                 tcp 6600
237

MANAGED FILES

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

FILE CONTEXTS

312       SELinux requires files to have an extended attribute to define the file
313       type.
314
315       You can see the context of a file using the -Z option to ls
316
317       Policy  governs  the  access  confined  processes  have to these files.
318       SELinux mpd policy is very flexible allowing users to setup  their  mpd
319       processes in as secure a method as possible.
320
321       EQUIVALENCE DIRECTORIES
322
323
324       mpd policy stores data with multiple different file context types under
325       the /var/lib/mpd directory.  If you would like to store the data  in  a
326       different  directory  you  can  use  the  semanage command to create an
327       equivalence mapping.  If you wanted to store this data under  the  /srv
328       dirctory you would execute the following command:
329
330       semanage fcontext -a -e /var/lib/mpd /srv/mpd
331       restorecon -R -v /srv/mpd
332
333       STANDARD FILE CONTEXT
334
335       SELinux  defines  the  file context types for the mpd, if you wanted to
336       store files with these types in a diffent paths, you  need  to  execute
337       the  semanage  command  to  sepecify  alternate  labeling  and then use
338       restorecon to put the labels on disk.
339
340       semanage fcontext -a -t mpd_var_run_t '/srv/mympd_content(/.*)?'
341       restorecon -R -v /srv/mympd_content
342
343       Note: SELinux often uses regular expressions  to  specify  labels  that
344       match multiple files.
345
346       The following file types are defined for mpd:
347
348
349
350       mpd_data_t
351
352       - Set files with the mpd_data_t type, if you want to treat the files as
353       mpd content.
354
355
356       Paths:
357            /var/lib/mpd/music(/.*)?, /var/lib/mpd/playlists(/.*)?
358
359
360       mpd_etc_t
361
362       - Set files with the mpd_etc_t type, if you want to store mpd files  in
363       the /etc directories.
364
365
366
367       mpd_exec_t
368
369       - Set files with the mpd_exec_t type, if you want to transition an exe‐
370       cutable to the mpd_t domain.
371
372
373
374       mpd_home_t
375
376       - Set files with the mpd_home_t type, if you want to store mpd files in
377       the users home directory.
378
379
380
381       mpd_initrc_exec_t
382
383       -  Set files with the mpd_initrc_exec_t type, if you want to transition
384       an executable to the mpd_initrc_t domain.
385
386
387
388       mpd_log_t
389
390       - Set files with the mpd_log_t type, if you want to treat the  data  as
391       mpd log data, usually stored under the /var/log directory.
392
393
394
395       mpd_tmp_t
396
397       - Set files with the mpd_tmp_t type, if you want to store mpd temporary
398       files in the /tmp directories.
399
400
401
402       mpd_tmpfs_t
403
404       - Set files with the mpd_tmpfs_t type, if you want to store  mpd  files
405       on a tmpfs file system.
406
407
408
409       mpd_user_data_t
410
411       -  Set  files  with  the mpd_user_data_t type, if you want to treat the
412       files as mpd user content.
413
414
415
416       mpd_var_lib_t
417
418       - Set files with the mpd_var_lib_t type, if you want to store  the  mpd
419       files under the /var/lib directory.
420
421
422
423       mpd_var_run_t
424
425       -  Set  files with the mpd_var_run_t type, if you want to store the mpd
426       files under the /run or /var/run directory.
427
428
429
430       Note: File context can be temporarily modified with the chcon  command.
431       If  you want to permanently change the file context you need to use the
432       semanage fcontext command.  This will modify the SELinux labeling data‐
433       base.  You will need to use restorecon to apply the labels.
434
435

COMMANDS

437       semanage  fcontext  can also be used to manipulate default file context
438       mappings.
439
440       semanage permissive can also be used to manipulate  whether  or  not  a
441       process type is permissive.
442
443       semanage  module can also be used to enable/disable/install/remove pol‐
444       icy modules.
445
446       semanage port can also be used to manipulate the port definitions
447
448       semanage boolean can also be used to manipulate the booleans
449
450
451       system-config-selinux is a GUI tool available to customize SELinux pol‐
452       icy settings.
