NAME

6       pulseaudio_selinux  - Security Enhanced Linux Policy for the pulseaudio
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  pulseaudio_t  SELinux  type  can  be  entered via the user_home_t,
25       pulseaudio_exec_t file types.
26
27       The default entrypoint paths for the pulseaudio_t domain are  the  fol‐
28       lowing:
29
30       /home/[^/]*/.+, /home/staff/.+, /usr/bin/pulseaudio
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       pulseaudio  policy  is  very  flexible  allowing  users  to setup their
40       pulseaudio processes in as secure a method as possible.
41
42       The following process types are defined for pulseaudio:
43
44       pulseaudio_t
45
46       Note: semanage permissive -a pulseaudio_t  can  be  used  to  make  the
47       process  type  pulseaudio_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

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

PORT TYPES

183       SELinux defines port types to represent TCP and UDP ports.
184
185       You can see the types associated with a port  by  using  the  following
186       command:
187
188       semanage port -l
189
190
191       Policy  governs  the  access  confined  processes  have to these ports.
192       SELinux pulseaudio policy is very  flexible  allowing  users  to  setup
193       their pulseaudio processes in as secure a method as possible.
194
195       The following port types are defined for pulseaudio:
196
197
198       pulseaudio_port_t
199
200
201
202       Default Defined Ports:
203                 tcp 4713
204                 udp 4713
205

MANAGED FILES

207       The SELinux process type pulseaudio_t can manage files labeled with the
208       following file types.  The paths listed are the default paths for these
209       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

323       SELinux requires files to have an extended attribute to define the file
324       type.
325
326       You can see the context of a file using the -Z option to ls
327
328       Policy governs the access  confined  processes  have  to  these  files.
329       SELinux  pulseaudio  policy  is  very  flexible allowing users to setup
330       their pulseaudio processes in as secure a method as possible.
331
332       STANDARD FILE CONTEXT
333
334       SELinux defines the file context  types  for  the  pulseaudio,  if  you
335       wanted  to store files with these types in a diffent paths, you need to
336       execute the semanage command to sepecify alternate  labeling  and  then
337       use restorecon to put the labels on disk.
338
339       semanage  fcontext  -a  -t pulseaudio_var_run_t '/srv/mypulseaudio_con‐
340       tent(/.*)?'
341       restorecon -R -v /srv/mypulseaudio_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 pulseaudio:
347
348
349
350       pulseaudio_exec_t
351
352       -  Set files with the pulseaudio_exec_t type, if you want to transition
353       an executable to the pulseaudio_t domain.
354
355
356
357       pulseaudio_home_t
358
359       - Set files with the pulseaudio_home_t  type,  if  you  want  to  store
360       pulseaudio files in the users home directory.
361
362
363       Paths:
364            /home/[^/]*/.pulse(/.*)?,               /home/[^/]*/.pulse-cookie,
365            /home/staff/.pulse(/.*)?, /home/staff/.pulse-cookie
366
367
368       pulseaudio_tmpfs_t
369
370       - Set files with the pulseaudio_tmpfs_t type,  if  you  want  to  store
371       pulseaudio files on a tmpfs file system.
372
373
374
375       pulseaudio_var_lib_t
376
377       -  Set  files  with the pulseaudio_var_lib_t type, if you want to store
378       the pulseaudio files under the /var/lib directory.
379
380
381
382       pulseaudio_var_run_t
383
384       - Set files with the pulseaudio_var_run_t type, if you  want  to  store
385       the pulseaudio files under the /run or /var/run directory.
386
387
388
389       Note:  File context can be temporarily modified with the chcon command.
390       If you want to permanently change the file context you need to use  the
391       semanage fcontext command.  This will modify the SELinux labeling data‐
392       base.  You will need to use restorecon to apply the labels.
393
394

COMMANDS

396       semanage fcontext can also be used to manipulate default  file  context
397       mappings.
398
399       semanage  permissive  can  also  be used to manipulate whether or not a
400       process type is permissive.
401
402       semanage module can also be used to enable/disable/install/remove  pol‐
403       icy modules.
404
405       semanage port can also be used to manipulate the port definitions
406
407       semanage boolean can also be used to manipulate the booleans
408
409
410       system-config-selinux is a GUI tool available to customize SELinux pol‐
411       icy settings.
