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

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

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

COMMANDS

287       semanage  fcontext  can also be used to manipulate default file context
288       mappings.
289
290       semanage permissive can also be used to manipulate  whether  or  not  a
291       process type is permissive.
292
293       semanage  module can also be used to enable/disable/install/remove pol‐
294       icy modules.
295
296       semanage boolean can also be used to manipulate the booleans
297
298
299       system-config-selinux is a GUI tool available to customize SELinux pol‐
300       icy settings.
