6 tuned_selinux - Security Enhanced Linux Policy for the tuned processes
7
9 Security-Enhanced Linux secures the tuned processes via flexible manda‐
10 tory access control.
11
12 The tuned processes execute with the tuned_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep tuned_t
19
20
21
23 The tuned_t SELinux type can be entered via the tuned_exec_t file type.
24
25 The default entrypoint paths for the tuned_t domain are the following:
26
27 /usr/sbin/tuned
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 tuned policy is very flexible allowing users to setup their tuned pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for tuned:
40
41 tuned_t
42
43 Note: semanage permissive -a tuned_t can be used to make the process
44 type tuned_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. tuned
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run tuned with the tightest access possible.

238 SELinux requires files to have an extended attribute to define the file
239 type.
240
241 You can see the context of a file using the -Z option to ls
242
243 Policy governs the access confined processes have to these files.
244 SELinux tuned policy is very flexible allowing users to setup their
245 tuned processes in as secure a method as possible.
246
247 EQUIVALENCE DIRECTORIES
248
249
250 tuned policy stores data with multiple different file context types
251 under the /var/log/tuned directory. If you would like to store the
252 data in a different directory you can use the semanage command to cre‐
253 ate an equivalence mapping. If you wanted to store this data under the
254 /srv dirctory you would execute the following command:
255
256 semanage fcontext -a -e /var/log/tuned /srv/tuned
257 restorecon -R -v /srv/tuned
258
259 tuned policy stores data with multiple different file context types
260 under the /var/run/tuned directory. If you would like to store the
261 data in a different directory you can use the semanage command to cre‐
262 ate an equivalence mapping. If you wanted to store this data under the
263 /srv dirctory you would execute the following command:
264
265 semanage fcontext -a -e /var/run/tuned /srv/tuned
266 restorecon -R -v /srv/tuned
267
268 STANDARD FILE CONTEXT
269
270 SELinux defines the file context types for the tuned, if you wanted to
271 store files with these types in a diffent paths, you need to execute
272 the semanage command to sepecify alternate labeling and then use
273 restorecon to put the labels on disk.
274
275 semanage fcontext -a -t tuned_var_run_t '/srv/mytuned_content(/.*)?'
276 restorecon -R -v /srv/mytuned_content
277
278 Note: SELinux often uses regular expressions to specify labels that
279 match multiple files.
280
281 The following file types are defined for tuned:
282
283
284
285 tuned_etc_t
286
287 - Set files with the tuned_etc_t type, if you want to store tuned files
288 in the /etc directories.
289
290
291
292 tuned_exec_t
293
294 - Set files with the tuned_exec_t type, if you want to transition an
295 executable to the tuned_t domain.
296
297
298
299 tuned_initrc_exec_t
300
301 - Set files with the tuned_initrc_exec_t type, if you want to transi‐
302 tion an executable to the tuned_initrc_t domain.
303
304
305 Paths:
306 /etc/rc.d/init.d/tuned, /etc/rc.d/init.d/ktune
307
308
309 tuned_log_t
310
311 - Set files with the tuned_log_t type, if you want to treat the data as
312 tuned log data, usually stored under the /var/log directory.
313
314
315 Paths:
316 /var/log/tuned(/.*)?, /var/log/tuned.log.*
317
318
319 tuned_rw_etc_t
320
321 - Set files with the tuned_rw_etc_t type, if you want to store tuned rw
322 files in the /etc directories.
323
324
325
326 tuned_tmp_t
327
328 - Set files with the tuned_tmp_t type, if you want to store tuned tem‐
329 porary files in the /tmp directories.
330
331
332
333 tuned_var_lock_t
334
335 - Set files with the tuned_var_lock_t type, if you want to treat the
336 files as tuned var lock data, stored under the /var/lock directory
337
338
339
340 tuned_var_run_t
341
342 - Set files with the tuned_var_run_t type, if you want to store the
343 tuned files under the /run or /var/run directory.
344
345
346 Paths:
347 /var/run/tuned(/.*)?, /var/run/tuned.pid, /var/run/ktune.save
348
349
350 Note: File context can be temporarily modified with the chcon command.
351 If you want to permanently change the file context you need to use the
352 semanage fcontext command. This will modify the SELinux labeling data‐
353 base. You will need to use restorecon to apply the labels.
354
355
357 semanage fcontext can also be used to manipulate default file context
358 mappings.
359
360 semanage permissive can also be used to manipulate whether or not a
361 process type is permissive.
362
363 semanage module can also be used to enable/disable/install/remove pol‐
364 icy modules.
365
366 semanage boolean can also be used to manipulate the booleans
367
368
369 system-config-selinux is a GUI tool available to customize SELinux pol‐
370 icy settings.
