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
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 cpucontrol policy is very flexible allowing users to setup their cpu‐
40 control processes in as secure a method as possible.
41
42 The following process types are defined for cpucontrol:
43
44 cpucontrol_t
45
46 Note: semanage permissive -a cpucontrol_t can be used to make the
47 process type cpucontrol_t permissive. SELinux does not deny access to
48 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. cpucon‐
54 trol policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run cpucontrol with the tightest
56 access possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow confined applications to use nscd shared memory,
68 you must turn on the nscd_use_shm boolean. Disabled by default.
69
70 setsebool -P nscd_use_shm 1
71
72
73
75 SELinux requires files to have an extended attribute to define the file
76 type.
77
78 You can see the context of a file using the -Z option to ls
79
80 Policy governs the access confined processes have to these files.
81 SELinux cpucontrol policy is very flexible allowing users to setup
82 their cpucontrol processes in as secure a method as possible.
83
84 STANDARD FILE CONTEXT
85
86 SELinux defines the file context types for the cpucontrol, if you
87 wanted to store files with these types in a diffent paths, you need to
88 execute the semanage command to sepecify alternate labeling and then
89 use restorecon to put the labels on disk.
90
91 semanage fcontext -a -t cpucontrol_conf_t '/srv/mycpucontrol_con‐
92 tent(/.*)?'
93 restorecon -R -v /srv/mycpucontrol_content
94
95 Note: SELinux often uses regular expressions to specify labels that
96 match multiple files.
97
98 The following file types are defined for cpucontrol:
99
100
101
102 cpucontrol_conf_t
103
104 - Set files with the cpucontrol_conf_t type, if you want to treat the
105 files as cpucontrol configuration data, usually stored under the /etc
106 directory.
107
108
109
110 cpucontrol_exec_t
111
112 - Set files with the cpucontrol_exec_t type, if you want to transition
113 an executable to the cpucontrol_t domain.
114
115
116 Paths:
117 /sbin/microcode_ctl, /usr/sbin/microcode_ctl
118
119
120 Note: File context can be temporarily modified with the chcon command.
121 If you want to permanently change the file context you need to use the
122 semanage fcontext command. This will modify the SELinux labeling data‐
123 base. You will need to use restorecon to apply the labels.
124
125
127 semanage fcontext can also be used to manipulate default file context
128 mappings.
129
130 semanage permissive can also be used to manipulate whether or not a
131 process type is permissive.
132
133 semanage module can also be used to enable/disable/install/remove pol‐
134 icy modules.
135
136 semanage boolean can also be used to manipulate the booleans
137
138
139 system-config-selinux is a GUI tool available to customize SELinux pol‐
140 icy settings.
