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

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.

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
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.
