NAME

6       ksmtuned_selinux - Security Enhanced Linux Policy for the ksmtuned pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  ksmtuned  processes  via  flexible
11       mandatory access control.
12
13       The  ksmtuned  processes  execute with the ksmtuned_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep ksmtuned_t
20
21
22

ENTRYPOINTS

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

MANAGED FILES

185       The SELinux process type ksmtuned_t can manage files labeled  with  the
186       following file types.  The paths listed are the default paths for these
187       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

234       SELinux requires files to have an extended attribute to define the file
235       type.
236
237       You can see the context of a file using the -Z option to ls
238
239       Policy  governs  the  access  confined  processes  have to these files.
240       SELinux ksmtuned policy is very flexible allowing users to setup  their
241       ksmtuned processes in as secure a method as possible.
242
243       STANDARD FILE CONTEXT
244
245       SELinux  defines the file context types for the ksmtuned, if you wanted
246       to store files with these types in a diffent paths, you need to execute
247       the  semanage  command  to  sepecify  alternate  labeling  and then use
248       restorecon to put the labels on disk.
249
250       semanage  fcontext  -a  -t   ksmtuned_var_run_t   '/srv/myksmtuned_con‐
251       tent(/.*)?'
252       restorecon -R -v /srv/myksmtuned_content
253
254       Note:  SELinux  often  uses  regular expressions to specify labels that
255       match multiple files.
256
257       The following file types are defined for ksmtuned:
258
259
260
261       ksmtuned_exec_t
262
263       - Set files with the ksmtuned_exec_t type, if you want to transition an
264       executable to the ksmtuned_t domain.
265
266
267
268       ksmtuned_initrc_exec_t
269
270       -  Set files with the ksmtuned_initrc_exec_t type, if you want to tran‐
271       sition an executable to the ksmtuned_initrc_t domain.
272
273
274
275       ksmtuned_log_t
276
277       - Set files with the ksmtuned_log_t type, if you want to treat the data
278       as ksmtuned log data, usually stored under the /var/log directory.
279
280
281
282       ksmtuned_unit_file_t
283
284       -  Set  files  with the ksmtuned_unit_file_t type, if you want to treat
285       the files as ksmtuned unit content.
286
287
288
289       ksmtuned_var_run_t
290
291       - Set files with the ksmtuned_var_run_t type, if you want to store  the
292       ksmtuned files under the /run or /var/run directory.
293
294
295
296       Note:  File context can be temporarily modified with the chcon command.
297       If you want to permanently change the file context you need to use  the
298       semanage fcontext command.  This will modify the SELinux labeling data‐
299       base.  You will need to use restorecon to apply the labels.
300
301

COMMANDS

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