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.
50
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

66

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 diffent paths, you need to execute
95       the semanage command  to  sepecify  alternate  labeling  and  then  use
96       restorecon to put the labels on disk.
97
98       semanage   fcontext   -a  -t  cpuspeed_var_run_t  '/srv/mycpuspeed_con‐
99       tent(/.*)?'
100       restorecon -R -v /srv/mycpuspeed_content
101
102       Note: SELinux often uses regular expressions  to  specify  labels  that
103       match multiple files.
104
105       The following file types are defined for cpuspeed:
106
107
108
109       cpuspeed_exec_t
110
111       - Set files with the cpuspeed_exec_t type, if you want to transition an
112       executable to the cpuspeed_t domain.
113
114
115       Paths:
116            /usr/sbin/cpufreqd, /usr/sbin/cpuspeed, /usr/sbin/powernowd
117
118
119       cpuspeed_var_run_t
120
121       - Set files with the cpuspeed_var_run_t type, if you want to store  the
122       cpuspeed files under the /run or /var/run directory.
123
124
125
126       Note:  File context can be temporarily modified with the chcon command.
127       If you want to permanently change the file context you need to use  the
128       semanage fcontext command.  This will modify the SELinux labeling data‐
129       base.  You will need to use restorecon to apply the labels.
130
131

COMMANDS

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