6 cpucontrol_selinux - Security Enhanced Linux Policy for the cpucontrol
7 processes
8
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
21
22
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
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
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 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
73
74
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 sysfs_t
81
82 /sys(/.*)?
83
84
86 SELinux requires files to have an extended attribute to define the file
87 type.
88
89 You can see the context of a file using the -Z option to ls
90
91 Policy governs the access confined processes have to these files.
92 SELinux cpucontrol policy is very flexible allowing users to setup
93 their cpucontrol processes in as secure a method as possible.
94
95 STANDARD FILE CONTEXT
96
97 SELinux defines the file context types for the cpucontrol, if you
98 wanted to store files with these types in a diffent paths, you need to
99 execute the semanage command to sepecify alternate labeling and then
100 use restorecon to put the labels on disk.
101
102 semanage fcontext -a -t cpucontrol_conf_t '/srv/mycpucontrol_con‐
103 tent(/.*)?'
104 restorecon -R -v /srv/mycpucontrol_content
105
106 Note: SELinux often uses regular expressions to specify labels that
107 match multiple files.
108
109 The following file types are defined for cpucontrol:
110
111
112
113 cpucontrol_conf_t
114
115 - Set files with the cpucontrol_conf_t type, if you want to treat the
116 files as cpucontrol configuration data, usually stored under the /etc
117 directory.
118
119
120
121 cpucontrol_exec_t
122
123 - Set files with the cpucontrol_exec_t type, if you want to transition
124 an executable to the cpucontrol_t domain.
125
126
127 Paths:
128 /sbin/microcode_ctl, /usr/sbin/microcode_ctl,
129 /usr/libexec/microcode_ctl/reload_microcode
130
131
132 Note: File context can be temporarily modified with the chcon command.
133 If you want to permanently change the file context you need to use the
134 semanage fcontext command. This will modify the SELinux labeling data‐
135 base. You will need to use restorecon to apply the labels.
136
137
139 semanage fcontext can also be used to manipulate default file context
140 mappings.
141
142 semanage permissive can also be used to manipulate whether or not a
143 process type is permissive.
144
145 semanage module can also be used to enable/disable/install/remove pol‐
146 icy modules.
147
148 semanage boolean can also be used to manipulate the booleans
149
150
151 system-config-selinux is a GUI tool available to customize SELinux pol‐
152 icy settings.
