NAME

6       timemaster_selinux  - Security Enhanced Linux Policy for the timemaster
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the timemaster processes  via  flexible
11       mandatory access control.
12
13       The  timemaster  processes  execute with the timemaster_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 timemaster_t
20
21
22

ENTRYPOINTS

24       The  timemaster_t SELinux type can be entered via the timemaster_exec_t
25       file type.
26
27       The default entrypoint paths for the timemaster_t domain are  the  fol‐
28       lowing:
29
30       /usr/sbin/timemaster
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       timemaster  policy  is  very  flexible  allowing  users  to setup their
40       timemaster processes in as secure a method as possible.
41
42       The following process types are defined for timemaster:
43
44       timemaster_t
45
46       Note: semanage permissive -a timemaster_t  can  be  used  to  make  the
47       process  type  timemaster_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       timemaster policy is extremely flexible and has several  booleans  that
55       allow you to manipulate the policy and run timemaster with the tightest
56       access possible.

MANAGED FILES

154       The SELinux process type timemaster_t can manage files labeled with the
155       following file types.  The paths listed are the default paths for these
156       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

230       SELinux requires files to have an extended attribute to define the file
231       type.
232
233       You can see the context of a file using the -Z option to ls
234
235       Policy governs the access  confined  processes  have  to  these  files.
236       SELinux  timemaster  policy  is  very  flexible allowing users to setup
237       their timemaster processes in as secure a method as possible.
238
239       STANDARD FILE CONTEXT
240
241       SELinux defines the file context  types  for  the  timemaster,  if  you
242       wanted  to store files with these types in a diffent paths, you need to
243       execute the semanage command to sepecify alternate  labeling  and  then
244       use restorecon to put the labels on disk.
245
246       semanage  fcontext  -a  -t timemaster_var_run_t '/srv/mytimemaster_con‐
247       tent(/.*)?'
248       restorecon -R -v /srv/mytimemaster_content
249
250       Note: SELinux often uses regular expressions  to  specify  labels  that
251       match multiple files.
252
253       The following file types are defined for timemaster:
254
255
256
257       timemaster_exec_t
258
259       -  Set files with the timemaster_exec_t type, if you want to transition
260       an executable to the timemaster_t domain.
261
262
263
264       timemaster_initrc_exec_t
265
266       - Set files with the timemaster_initrc_exec_t  type,  if  you  want  to
267       transition an executable to the timemaster_initrc_t domain.
268
269
270
271       timemaster_tmpfs_t
272
273       -  Set  files  with  the  timemaster_tmpfs_t type, if you want to store
274       timemaster files on a tmpfs file system.
275
276
277
278       timemaster_var_run_t
279
280       - Set files with the timemaster_var_run_t type, if you  want  to  store
281       the timemaster files under the /run or /var/run directory.
282
283
284
285       Note:  File context can be temporarily modified with the chcon command.
286       If you want to permanently change the file context you need to use  the
287       semanage fcontext command.  This will modify the SELinux labeling data‐
288       base.  You will need to use restorecon to apply the labels.
289
290

COMMANDS

292       semanage fcontext can also be used to manipulate default  file  context
293       mappings.
294
295       semanage  permissive  can  also  be used to manipulate whether or not a
296       process type is permissive.
297
298       semanage module can also be used to enable/disable/install/remove  pol‐
299       icy modules.
300
301       semanage boolean can also be used to manipulate the booleans
302
303
304       system-config-selinux is a GUI tool available to customize SELinux pol‐
305       icy settings.
