NAME

6       cpuspeed_selinux - Security Enhanced Linux Policy for the cpuspeed pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  cpuspeed  processes  via  flexible
11       mandatory access control.
12
13       The  cpuspeed  processes  execute with the cpuspeed_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 cpuspeed_t
20
21
22

ENTRYPOINTS

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

51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  cpus‐
54       peed policy is extremely flexible and has several booleans  that  allow
55       you  to manipulate the policy and run cpuspeed with the tightest access
56       possible.
57
58
59
60       If you want to allow all domains to execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1

MANAGED FILES

68       The  SELinux  process type cpuspeed_t can manage files labeled with the
69       following file types.  The paths listed are the default paths for these
70       file types.  Note the processes UID still need to have DAC permissions.
71
72       cpuspeed_var_run_t
73
74            /var/run/cpufreqd.pid
75
76       sysfs_t
77
78            /sys(/.*)?
79
80

FILE CONTEXTS

82       SELinux requires files to have an extended attribute to define the file
83       type.
84
85       You can see the context of a file using the -Z option to ls
86
87       Policy governs the access  confined  processes  have  to  these  files.
88       SELinux  cpuspeed policy is very flexible allowing users to setup their
89       cpuspeed processes in as secure a method as possible.
90
91       STANDARD FILE CONTEXT
92
93       SELinux defines the file context types for the cpuspeed, if you  wanted
94       to  store files with these types in a different paths, you need to exe‐
95       cute the semanage command to specify alternate labeling  and  then  use
96       restorecon to put the labels on disk.
97
98       semanage fcontext -a -t cpuspeed_exec_t '/srv/cpuspeed/content(/.*)?'
99       restorecon -R -v /srv/mycpuspeed_content
100
101       Note:  SELinux  often  uses  regular expressions to specify labels that
102       match multiple files.
103
104       The following file types are defined for cpuspeed:
105
106
107
108       cpuspeed_exec_t
109
110       - Set files with the cpuspeed_exec_t type, if you want to transition an
111       executable to the cpuspeed_t domain.
112
113
114       Paths:
115            /usr/sbin/cpufreqd, /usr/sbin/cpuspeed, /usr/sbin/powernowd
116
117
118       cpuspeed_var_run_t
119
120       -  Set files with the cpuspeed_var_run_t type, if you want to store the
121       cpuspeed files under the /run or /var/run directory.
122
123
124
125       Note: File context can be temporarily modified with the chcon  command.
126       If  you want to permanently change the file context you need to use the
127       semanage fcontext command.  This will modify the SELinux labeling data‐
128       base.  You will need to use restorecon to apply the labels.

COMMANDS

132       semanage  fcontext  can also be used to manipulate default file context
133       mappings.
134
135       semanage permissive can also be used to manipulate  whether  or  not  a
136       process type is permissive.
137
138       semanage  module can also be used to enable/disable/install/remove pol‐
139       icy modules.
140
141       semanage boolean can also be used to manipulate the booleans
142
143
144       system-config-selinux is a GUI tool available to customize SELinux pol‐
145       icy settings.
