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