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 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

MANAGED FILES

105       The SELinux process type cpuspeed_t can manage files labeled  with  the
106       following file types.  The paths listed are the default paths for these
107       file types.  Note the processes UID still need to have DAC permissions.
108
109       cpuspeed_var_run_t
110
111            /var/run/cpufreqd.pid
112
113       initrc_tmp_t
114
115
116       mnt_t
117
118            /mnt(/[^/]*)
119            /mnt(/[^/]*)?
120            /rhev(/[^/]*)?
121            /media(/[^/]*)
122            /media(/[^/]*)?
123            /etc/rhgb(/.*)?
124            /media/.hal-.*
125            /net
126            /afs
127            /rhev
128            /misc
129
130       sysfs_t
131
132            /sys(/.*)?
133
134       tmp_t
135
136            /tmp
137            /usr/tmp
138            /var/tmp
139            /tmp-inst
140            /var/tmp-inst
141            /var/tmp/vi.recover

FILE CONTEXTS

145       SELinux requires files to have an extended attribute to define the file
146       type.
147
148       You can see the context of a file using the -Z option to ls
149
150       Policy  governs  the  access  confined  processes  have to these files.
151       SELinux cpuspeed policy is very flexible allowing users to setup  their
152       cpuspeed processes in as secure a method as possible.
153
154       STANDARD FILE CONTEXT
155
156       SELinux  defines the file context types for the cpuspeed, if you wanted
157       to store files with these types in a diffent paths, you need to execute
158       the  semanage  command  to  sepecify  alternate  labeling  and then use
159       restorecon to put the labels on disk.
160
161       semanage  fcontext  -a  -t   cpuspeed_var_run_t   '/srv/mycpuspeed_con‐
162       tent(/.*)?'
163       restorecon -R -v /srv/mycpuspeed_content
164
165       Note:  SELinux  often  uses  regular expressions to specify labels that
166       match multiple files.
167
168       The following file types are defined for cpuspeed:
169
170
171
172       cpuspeed_exec_t
173
174       - Set files with the cpuspeed_exec_t type, if you want to transition an
175       executable to the cpuspeed_t domain.
176
177
178       Paths:
179            /usr/sbin/cpufreqd, /usr/sbin/cpuspeed, /usr/sbin/powernowd
180
181
182       cpuspeed_var_run_t
183
184       -  Set files with the cpuspeed_var_run_t type, if you want to store the
185       cpuspeed files under the /run or /var/run directory.
186
187
188
189       Note: File context can be temporarily modified with the chcon  command.
190       If  you want to permanently change the file context you need to use the
191       semanage fcontext command.  This will modify the SELinux labeling data‐
192       base.  You will need to use restorecon to apply the labels.
193
194

COMMANDS

196       semanage  fcontext  can also be used to manipulate default file context
197       mappings.
198
199       semanage permissive can also be used to manipulate  whether  or  not  a
200       process type is permissive.
201
202       semanage  module can also be used to enable/disable/install/remove pol‐
203       icy modules.
204
205       semanage boolean can also be used to manipulate the booleans
206
207
208       system-config-selinux is a GUI tool available to customize SELinux pol‐
209       icy settings.
