6 cpufreqselector_selinux - Security Enhanced Linux Policy for the
7 cpufreqselector processes
8
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
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
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.
50
51
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.
57
58
59
60 If you want to allow all daemons the ability to read/write terminals,
61 you must turn on the allow_daemons_use_tty boolean. Disabled by
62 default.
63
64 setsebool -P allow_daemons_use_tty 1
65
66
67
68 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70
71 setsebool -P allow_domain_fd_use 1
72
73
74
75 If you want to allow sysadm to debug or ptrace all processes, you must
76 turn on the allow_ptrace boolean. Disabled by default.
77
78 setsebool -P allow_ptrace 1
79
80
81
82 If you want to allow all domains to have the kernel load modules, you
83 must turn on the domain_kernel_load_modules boolean. Disabled by
84 default.
85
86 setsebool -P domain_kernel_load_modules 1
87
88
89
90 If you want to allow all domains to execute in fips_mode, you must turn
91 on the fips_mode boolean. Enabled by default.
92
93 setsebool -P fips_mode 1
94
95
96
97 If you want to enable reading of urandom for all domains, you must turn
98 on the global_ssp boolean. Disabled by default.
99
100 setsebool -P global_ssp 1
101
102
103
105 The SELinux process type cpufreqselector_t can manage files labeled
106 with the following file types. The paths listed are the default paths
107 for these file types. Note the processes UID still need to have DAC
108 permissions.

142 SELinux requires files to have an extended attribute to define the file
143 type.
144
145 You can see the context of a file using the -Z option to ls
146
147 Policy governs the access confined processes have to these files.
148 SELinux cpufreqselector policy is very flexible allowing users to setup
149 their cpufreqselector processes in as secure a method as possible.
150
151 The following file types are defined for cpufreqselector:
152
153
154
155 cpufreqselector_exec_t
156
157 - Set files with the cpufreqselector_exec_t type, if you want to tran‐
158 sition an executable to the cpufreqselector_t domain.
159
160
161
162 Note: File context can be temporarily modified with the chcon command.
163 If you want to permanently change the file context you need to use the
164 semanage fcontext command. This will modify the SELinux labeling data‐
165 base. You will need to use restorecon to apply the labels.
166
167
169 semanage fcontext can also be used to manipulate default file context
170 mappings.
171
172 semanage permissive can also be used to manipulate whether or not a
173 process type is permissive.
174
175 semanage module can also be used to enable/disable/install/remove pol‐
176 icy modules.
177
178 semanage boolean can also be used to manipulate the booleans
179
180
181 system-config-selinux is a GUI tool available to customize SELinux pol‐
182 icy settings.
