NAME

6       cpucontrol_selinux  - Security Enhanced Linux Policy for the cpucontrol
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the cpucontrol processes  via  flexible
11       mandatory access control.
12
13       The  cpucontrol  processes  execute with the cpucontrol_t SELinux type.
14       You can check if you have these processes running by executing  the  ps
15       command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep cpucontrol_t
20

22

ENTRYPOINTS

24       The  cpucontrol_t SELinux type can be entered via the cpucontrol_exec_t
25       file type.
26
27       The default entrypoint paths for the cpucontrol_t domain are  the  fol‐
28       lowing:
29
30       /sbin/microcode_ctl,                           /usr/sbin/microcode_ctl,
31       /usr/libexec/microcode_ctl/reload_microcode
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       cpucontrol policy is very flexible allowing users to setup  their  cpu‐
41       control processes in as secure a method as possible.
42
43       The following process types are defined for cpucontrol:
44
45       cpucontrol_t
46
47       Note:  semanage  permissive  -a  cpucontrol_t  can  be used to make the
48       process type cpucontrol_t permissive. SELinux does not deny  access  to
49       permissive  process  types,  but the AVC (SELinux denials) messages are
50       still generated.
51
52

BOOLEANS

54       SELinux policy is customizable based on least access required.  cpucon‐
55       trol  policy  is extremely flexible and has several booleans that allow
56       you to manipulate the policy  and  run  cpucontrol  with  the  tightest
57       access possible.
58
59
60
61       If you want to allow users to resolve user passwd entries directly from
62       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
63       gin_nsswitch_use_ldap boolean. Disabled by default.
64
65       setsebool -P authlogin_nsswitch_use_ldap 1
66
67
68
69       If you want to allow all domains to execute in fips_mode, you must turn
70       on the fips_mode boolean. Enabled by default.
71
72       setsebool -P fips_mode 1
73
74
75
76       If you want to allow confined applications to run  with  kerberos,  you
77       must turn on the kerberos_enabled boolean. Disabled by default.
78
79       setsebool -P kerberos_enabled 1
80
81
82
83       If  you  want  to  allow  system  to run with NIS, you must turn on the
84       nis_enabled boolean. Disabled by default.
85
86       setsebool -P nis_enabled 1
87
88
89
90       If you want to allow confined applications to use nscd  shared  memory,
91       you must turn on the nscd_use_shm boolean. Disabled by default.
92
93       setsebool -P nscd_use_shm 1

MANAGED FILES

98       The SELinux process type cpucontrol_t can manage files labeled with the
99       following file types.  The paths listed are the default paths for these
100       file types.  Note the processes UID still need to have DAC permissions.
101
102       sysfs_t
103
104            /sys(/.*)?
105
106

FILE CONTEXTS

108       SELinux requires files to have an extended attribute to define the file
109       type.
110
111       You can see the context of a file using the -Z option to ls
112
113       Policy governs the access  confined  processes  have  to  these  files.
114       SELinux  cpucontrol  policy  is  very  flexible allowing users to setup
115       their cpucontrol processes in as secure a method as possible.
116
117       STANDARD FILE CONTEXT
118
119       SELinux defines the file context  types  for  the  cpucontrol,  if  you
120       wanted  to store files with these types in a diffent paths, you need to
121       execute the semanage command to sepecify alternate  labeling  and  then
122       use restorecon to put the labels on disk.
123
124       semanage   fcontext  -a  -t  cpucontrol_conf_t  '/srv/mycpucontrol_con‐
125       tent(/.*)?'
126       restorecon -R -v /srv/mycpucontrol_content
127
128       Note: SELinux often uses regular expressions  to  specify  labels  that
129       match multiple files.
130
131       The following file types are defined for cpucontrol:
132
133
134
135       cpucontrol_conf_t
136
137       -  Set  files with the cpucontrol_conf_t type, if you want to treat the
138       files as cpucontrol configuration data, usually stored under  the  /etc
139       directory.
140
141
142
143       cpucontrol_exec_t
144
145       -  Set files with the cpucontrol_exec_t type, if you want to transition
146       an executable to the cpucontrol_t domain.
147
148
149       Paths:
150            /sbin/microcode_ctl,                      /usr/sbin/microcode_ctl,
151            /usr/libexec/microcode_ctl/reload_microcode
152
153
154       Note:  File context can be temporarily modified with the chcon command.
155       If you want to permanently change the file context you need to use  the
156       semanage fcontext command.  This will modify the SELinux labeling data‐
157       base.  You will need to use restorecon to apply the labels.

COMMANDS

161       semanage fcontext can also be used to manipulate default  file  context
162       mappings.
163
164       semanage  permissive  can  also  be used to manipulate whether or not a
165       process type is permissive.
166
167       semanage module can also be used to enable/disable/install/remove  pol‐
168       icy modules.
169
170       semanage boolean can also be used to manipulate the booleans
171
172
173       system-config-selinux is a GUI tool available to customize SELinux pol‐
174       icy settings.
