NAME

6       cpufreqselector_selinux  -  Security  Enhanced  Linux  Policy  for  the
7       cpufreqselector processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The cpufreqselector_t SELinux type can be entered via the cpufreqselec‐
25       tor_exec_t file type.
26
27       The default entrypoint paths for the cpufreqselector_t domain  are  the
28       following:
29
30       /usr/bin/cpufreq-selector
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       cpufreqselector  policy  is very flexible allowing users to setup their
40       cpufreqselector processes in as secure a method as possible.
41
42       The following process types are defined for cpufreqselector:
43
44       cpufreqselector_t
45
46       Note: semanage permissive -a cpufreqselector_t can be used to make  the
47       process type cpufreqselector_t permissive. SELinux does not deny access
48       to permissive process types, but the AVC (SELinux denials) messages are
49       still generated.

51

BOOLEANS

53       SELinux policy is customizable based on least access required.  cpufre‐
54       qselector policy is extremely flexible and has  several  booleans  that
55       allow  you  to  manipulate  the policy and run cpufreqselector with the
56       tightest access possible.

58
59
60       If you want to allow all daemons to write corefiles to /, you must turn
61       on the daemons_dump_core boolean. Disabled by default.

MANAGED FILES

142       The  SELinux  process  type  cpufreqselector_t can manage files labeled
143       with the following file types.  The paths listed are the default  paths
144       for  these  file  types.  Note the processes UID still need to have DAC
145       permissions.
146
147       cluster_conf_t
148
149            /etc/cluster(/.*)?

FILE CONTEXTS

188       SELinux requires files to have an extended attribute to define the file
189       type.
190
191       You can see the context of a file using the -Z option to ls
192
193       Policy  governs  the  access  confined  processes  have to these files.
194       SELinux cpufreqselector policy is very flexible allowing users to setup
195       their cpufreqselector processes in as secure a method as possible.
196
197       The following file types are defined for cpufreqselector:
198
199
200
201       cpufreqselector_exec_t
202
203       -  Set files with the cpufreqselector_exec_t type, if you want to tran‐
204       sition an executable to the cpufreqselector_t domain.
205
206
207
208       Note: File context can be temporarily modified with the chcon  command.
209       If  you want to permanently change the file context you need to use the
210       semanage fcontext command.  This will modify the SELinux labeling data‐
211       base.  You will need to use restorecon to apply the labels.
212
213

COMMANDS

215       semanage  fcontext  can also be used to manipulate default file context
216       mappings.
217
218       semanage permissive can also be used to manipulate  whether  or  not  a
219       process type is permissive.
220
221       semanage  module can also be used to enable/disable/install/remove pol‐
222       icy modules.
223
224       semanage boolean can also be used to manipulate the booleans
225
226
227       system-config-selinux is a GUI tool available to customize SELinux pol‐
228       icy settings.
