NAME

6       cpuplug_selinux  -  Security Enhanced Linux Policy for the cpuplug pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

MANAGED FILES

142       The  SELinux  process  type cpuplug_t can manage files labeled with the
143       following file types.  The paths listed are the default paths for these
144       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

193       SELinux requires files to have an extended attribute to define the file
194       type.
195
196       You can see the context of a file using the -Z option to ls
197
198       Policy governs the access  confined  processes  have  to  these  files.
199       SELinux  cpuplug  policy is very flexible allowing users to setup their
200       cpuplug processes in as secure a method as possible.
201
202       STANDARD FILE CONTEXT
203
204       SELinux defines the file context types for the cpuplug, if  you  wanted
205       to store files with these types in a diffent paths, you need to execute
206       the semanage command  to  sepecify  alternate  labeling  and  then  use
207       restorecon to put the labels on disk.
208
209       semanage   fcontext   -a   -t   cpuplug_var_run_t  '/srv/mycpuplug_con‐
210       tent(/.*)?'
211       restorecon -R -v /srv/mycpuplug_content
212
213       Note: SELinux often uses regular expressions  to  specify  labels  that
214       match multiple files.
215
216       The following file types are defined for cpuplug:
217
218
219
220       cpuplug_exec_t
221
222       -  Set files with the cpuplug_exec_t type, if you want to transition an
223       executable to the cpuplug_t domain.
224
225
226
227       cpuplug_initrc_exec_t
228
229       - Set files with the cpuplug_initrc_exec_t type, if you want to transi‐
230       tion an executable to the cpuplug_initrc_t domain.
231
232
233
234       cpuplug_lock_t
235
236       -  Set  files  with  the  cpuplug_lock_t type, if you want to treat the
237       files as cpuplug lock data, stored under the /var/lock directory
238
239
240
241       cpuplug_var_run_t
242
243       - Set files with the cpuplug_var_run_t type, if you want to  store  the
244       cpuplug files under the /run or /var/run directory.
245
246
247
248       Note:  File context can be temporarily modified with the chcon command.
249       If you want to permanently change the file context you need to use  the
250       semanage fcontext command.  This will modify the SELinux labeling data‐
251       base.  You will need to use restorecon to apply the labels.
252
253

COMMANDS

255       semanage fcontext can also be used to manipulate default  file  context
256       mappings.
257
258       semanage  permissive  can  also  be used to manipulate whether or not a
259       process type is permissive.
260
261       semanage module can also be used to enable/disable/install/remove  pol‐
262       icy modules.
263
264       semanage boolean can also be used to manipulate the booleans
265
266
267       system-config-selinux is a GUI tool available to customize SELinux pol‐
268       icy settings.
