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
64
65
66
67       If  you  want to allow confined applications to use nscd shared memory,
68       you must turn on the nscd_use_shm boolean. Disabled by default.
69
70       setsebool -P nscd_use_shm 1
71
72
73

MANAGED FILES

75       The SELinux process type cpuspeed_t can manage files labeled  with  the
76       following file types.  The paths listed are the default paths for these
77       file types.  Note the processes UID still need to have DAC permissions.
78
79       cpuspeed_var_run_t
80
81            /var/run/cpufreqd.pid
82
83       sysfs_t
84
85            /sys(/.*)?
86
87

FILE CONTEXTS

89       SELinux requires files to have an extended attribute to define the file
90       type.
91
92       You can see the context of a file using the -Z option to ls
93
94       Policy  governs  the  access  confined  processes  have to these files.
95       SELinux cpuspeed policy is very flexible allowing users to setup  their
96       cpuspeed processes in as secure a method as possible.
97
98       STANDARD FILE CONTEXT
99
100       SELinux  defines the file context types for the cpuspeed, if you wanted
101       to store files with these types in a diffent paths, you need to execute
102       the  semanage  command  to  sepecify  alternate  labeling  and then use
103       restorecon to put the labels on disk.
104
105       semanage  fcontext  -a  -t   cpuspeed_var_run_t   '/srv/mycpuspeed_con‐
106       tent(/.*)?'
107       restorecon -R -v /srv/mycpuspeed_content
108
109       Note:  SELinux  often  uses  regular expressions to specify labels that
110       match multiple files.
111
112       The following file types are defined for cpuspeed:
113
114
115
116       cpuspeed_exec_t
117
118       - Set files with the cpuspeed_exec_t type, if you want to transition an
119       executable to the cpuspeed_t domain.
120
121
122       Paths:
123            /usr/sbin/cpufreqd, /usr/sbin/cpuspeed, /usr/sbin/powernowd
124
125
126       cpuspeed_var_run_t
127
128       -  Set files with the cpuspeed_var_run_t type, if you want to store the
129       cpuspeed files under the /run or /var/run directory.
130
131
132
133       Note: File context can be temporarily modified with the chcon  command.
134       If  you want to permanently change the file context you need to use the
135       semanage fcontext command.  This will modify the SELinux labeling data‐
136       base.  You will need to use restorecon to apply the labels.
137
138

COMMANDS

140       semanage  fcontext  can also be used to manipulate default file context
141       mappings.
142
143       semanage permissive can also be used to manipulate  whether  or  not  a
144       process type is permissive.
145
146       semanage  module can also be used to enable/disable/install/remove pol‐
147       icy modules.
148
149       semanage boolean can also be used to manipulate the booleans
150
151
152       system-config-selinux is a GUI tool available to customize SELinux pol‐
153       icy settings.
