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

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,     /usr/libexec/mi‐
31       crocode_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  ac‐
57       cess possible.
58
59
60
61       If you want to allow all domains to execute in fips_mode, you must turn
62       on the fips_mode boolean. Enabled by default.
63
64       setsebool -P fips_mode 1
65
66
67
68       If you want to allow system to run with  NIS,  you  must  turn  on  the
69       nis_enabled boolean. Disabled by default.
70
71       setsebool -P nis_enabled 1
72

74

MANAGED FILES

76       The SELinux process type cpucontrol_t can manage files labeled with the
77       following file types.  The paths listed are the default paths for these
78       file types.  Note the processes UID still need to have DAC permissions.
79
80       krb5_host_rcache_t
81
82            /var/tmp/krb5_0.rcache2
83            /var/cache/krb5rcache(/.*)?
84            /var/tmp/nfs_0
85            /var/tmp/DNS_25
86            /var/tmp/host_0
87            /var/tmp/imap_0
88            /var/tmp/HTTP_23
89            /var/tmp/HTTP_48
90            /var/tmp/ldap_55
91            /var/tmp/ldap_487
92            /var/tmp/ldapmap1_0
93
94       sysfs_t
95
96            /sys(/.*)?

FILE CONTEXTS

100       SELinux requires files to have an extended attribute to define the file
101       type.
102
103       You can see the context of a file using the -Z option to ls
104
105       Policy governs the access  confined  processes  have  to  these  files.
106       SELinux  cpucontrol  policy  is  very  flexible allowing users to setup
107       their cpucontrol processes in as secure a method as possible.
108
109       STANDARD FILE CONTEXT
110
111       SELinux defines the file context  types  for  the  cpucontrol,  if  you
112       wanted  to  store files with these types in a different paths, you need
113       to execute the semanage command to specify alternate labeling and  then
114       use restorecon to put the labels on disk.
115
116       semanage   fcontext   -a   -t  cpucontrol_exec_t  '/srv/cpucontrol/con‐
117       tent(/.*)?'
118       restorecon -R -v /srv/mycpucontrol_content
119
120       Note: SELinux often uses regular expressions  to  specify  labels  that
121       match multiple files.
122
123       The following file types are defined for cpucontrol:
124
125
126
127       cpucontrol_conf_t
128
129       -  Set  files with the cpucontrol_conf_t type, if you want to treat the
130       files as cpucontrol configuration data, usually stored under  the  /etc
131       directory.
132
133
134
135       cpucontrol_exec_t
136
137       -  Set files with the cpucontrol_exec_t type, if you want to transition
138       an executable to the cpucontrol_t domain.
139
140
141       Paths:
142            /sbin/microcode_ctl,   /usr/sbin/microcode_ctl,   /usr/libexec/mi‐
143            crocode_ctl/reload_microcode
144
145
146       Note:  File context can be temporarily modified with the chcon command.
147       If you want to permanently change the file context you need to use  the
148       semanage fcontext command.  This will modify the SELinux labeling data‐
149       base.  You will need to use restorecon to apply the labels.

151

COMMANDS

153       semanage fcontext can also be used to manipulate default  file  context
154       mappings.
155
156       semanage  permissive  can  also  be used to manipulate whether or not a
157       process type is permissive.
158
159       semanage module can also be used to enable/disable/install/remove  pol‐
160       icy modules.
161
162       semanage boolean can also be used to manipulate the booleans
163
164
165       system-config-selinux is a GUI tool available to customize SELinux pol‐
166       icy settings.
