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 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 For example:
18 ps -eZ | grep cpucontrol_t
20
24 The cpucontrol_t SELinux type can be entered via the cpucontrol_exec_t
25 file type.
26 The default entrypoint paths for the cpucontrol_t domain are the fol‐
28 lowing:
29 /sbin/microcode_ctl
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for cpucontrol:
43 cpucontrol_t
45 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
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 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 setsebool -P allow_daemons_use_tty 1
65 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 setsebool -P allow_domain_fd_use 1
72 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 setsebool -P allow_ptrace 1
79 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 setsebool -P domain_kernel_load_modules 1
87 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 setsebool -P fips_mode 1
94 If you want to enable reading of urandom for all domains, you must turn
98 on the global_ssp boolean. Disabled by default.
99 setsebool -P global_ssp 1

105 The SELinux process type cpucontrol_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 initrc_tmp_t
110 mnt_t
113 /mnt(/[^/]*)
115 /mnt(/[^/]*)?
116 /rhev(/[^/]*)?
117 /media(/[^/]*)
118 /media(/[^/]*)?
119 /etc/rhgb(/.*)?
120 /media/.hal-.*
121 /net
122 /afs
123 /rhev
124 /misc
125 tmp_t
127 /tmp
129 /usr/tmp
130 /var/tmp
131 /tmp-inst
132 /var/tmp-inst
133 /var/tmp/vi.recover

137 SELinux requires files to have an extended attribute to define the file
138 type.
139 You can see the context of a file using the -Z option to ls
141 Policy governs the access confined processes have to these files.
143 SELinux cpucontrol policy is very flexible allowing users to setup
144 their cpucontrol processes in as secure a method as possible.
145 STANDARD FILE CONTEXT
147 SELinux defines the file context types for the cpucontrol, if you
149 wanted to store files with these types in a diffent paths, you need to
150 execute the semanage command to sepecify alternate labeling and then
151 use restorecon to put the labels on disk.
152 semanage fcontext -a -t cpucontrol_conf_t '/srv/mycpucontrol_con‐
154 tent(/.*)?'
155 restorecon -R -v /srv/mycpucontrol_content
156 Note: SELinux often uses regular expressions to specify labels that
158 match multiple files.
159 The following file types are defined for cpucontrol:
161 cpucontrol_conf_t
165 - Set files with the cpucontrol_conf_t type, if you want to treat the
167 files as cpucontrol configuration data, usually stored under the /etc
168 directory.
169 cpucontrol_exec_t
173 - Set files with the cpucontrol_exec_t type, if you want to transition
175 an executable to the cpucontrol_t domain.
176 Note: File context can be temporarily modified with the chcon command.
180 If you want to permanently change the file context you need to use the
181 semanage fcontext command. This will modify the SELinux labeling data‐
182 base. You will need to use restorecon to apply the labels.
183
186 semanage fcontext can also be used to manipulate default file context
187 mappings.
188 semanage permissive can also be used to manipulate whether or not a
190 process type is permissive.
191 semanage module can also be used to enable/disable/install/remove pol‐
193 icy modules.
194 semanage boolean can also be used to manipulate the booleans
196 system-config-selinux is a GUI tool available to customize SELinux pol‐
199 icy settings.
