NAME

6       icecast_selinux  -  Security Enhanced Linux Policy for the icecast pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  icecast  processes  via  flexible
11       mandatory access control.
12
13       The  icecast processes execute with the icecast_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 icecast_t
20
21
22

ENTRYPOINTS

24       The  icecast_t  SELinux type can be entered via the icecast_exec_t file
25       type.
26
27       The default entrypoint paths for the icecast_t domain are  the  follow‐
28       ing:
29
30       /usr/bin/icecast
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       icecast  policy  is very flexible allowing users to setup their icecast
40       processes in as secure a method as possible.
41
42       The following process types are defined for icecast:
43
44       icecast_t
45
46       Note: semanage permissive -a icecast_t can be used to make the  process
47       type  icecast_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

BOOLEANS

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

MANAGED FILES

179       The SELinux process type icecast_t can manage files  labeled  with  the
180       following file types.  The paths listed are the default paths for these
181       file types.  Note the processes UID still need to have DAC permissions.
182

184
185            /etc/cluster(/.*)?

FILE CONTEXTS

225       SELinux requires files to have an extended attribute to define the file
226       type.
227
228       You can see the context of a file using the -Z option to ls
229
230       Policy  governs  the  access  confined  processes  have to these files.
231       SELinux icecast policy is very flexible allowing users to  setup  their
232       icecast processes in as secure a method as possible.
233
234       EQUIVALENCE DIRECTORIES
235
236
237       icecast  policy  stores data with multiple different file context types
238       under the /var/run/icecast directory.  If you would like to  store  the
239       data  in a different directory you can use the semanage command to cre‐
240       ate an equivalence mapping.  If you wanted to store this data under the
241       /srv dirctory you would execute the following command:
242
243       semanage fcontext -a -e /var/run/icecast /srv/icecast
244       restorecon -R -v /srv/icecast
245
246       STANDARD FILE CONTEXT
247
248       SELinux  defines  the file context types for the icecast, if you wanted
249       to store files with these types in a diffent paths, you need to execute
250       the  semanage  command  to  sepecify  alternate  labeling  and then use
251       restorecon to put the labels on disk.
252
253       semanage  fcontext   -a   -t   icecast_var_run_t   '/srv/myicecast_con‐
254       tent(/.*)?'
255       restorecon -R -v /srv/myicecast_content
256
257       Note:  SELinux  often  uses  regular expressions to specify labels that
258       match multiple files.
259
260       The following file types are defined for icecast:
261
262
263
264       icecast_exec_t
265
266       - Set files with the icecast_exec_t type, if you want to transition  an
267       executable to the icecast_t domain.
268
269
270
271       icecast_initrc_exec_t
272
273       - Set files with the icecast_initrc_exec_t type, if you want to transi‐
274       tion an executable to the icecast_initrc_t domain.
275
276
277
278       icecast_log_t
279
280       - Set files with the icecast_log_t type, if you want to treat the  data
281       as icecast log data, usually stored under the /var/log directory.
282
283
284
285       icecast_var_run_t
286
287       -  Set  files with the icecast_var_run_t type, if you want to store the
288       icecast files under the /run or /var/run directory.
289
290
291       Paths:
292            /var/run/icecast(/.*)?, /var/run/icecast.pid
293
294
295       Note: File context can be temporarily modified with the chcon  command.
296       If  you want to permanently change the file context you need to use the
297       semanage fcontext command.  This will modify the SELinux labeling data‐
298       base.  You will need to use restorecon to apply the labels.

COMMANDS

302       semanage  fcontext  can also be used to manipulate default file context
303       mappings.
304
305       semanage permissive can also be used to manipulate  whether  or  not  a
306       process type is permissive.
307
308       semanage  module can also be used to enable/disable/install/remove pol‐
309       icy modules.
310
311       semanage boolean can also be used to manipulate the booleans
312
313
314       system-config-selinux is a GUI tool available to customize SELinux pol‐
315       icy settings.
