6 cpuplug_selinux - Security Enhanced Linux Policy for the cpuplug pro‐
7 cesses
8
10 Security-Enhanced Linux secures the cpuplug processes via flexible
11 mandatory access control.
12 The cpuplug processes execute with the cpuplug_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep cpuplug_t
20
24 The cpuplug_t SELinux type can be entered via the cpuplug_exec_t file
25 type.
26 The default entrypoint paths for the cpuplug_t domain are the follow‐
28 ing:
29 /usr/sbin/cpuplugd
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 cpuplug policy is very flexible allowing users to setup their cpuplug
40 processes in as secure a method as possible.
41 The following process types are defined for cpuplug:
43 cpuplug_t
45 Note: semanage permissive -a cpuplug_t can be used to make the process
47 type cpuplug_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. cpuplug
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run cpuplug with the tightest access possi‐
56 ble.
57 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 setsebool -P fips_mode 1

68 The SELinux process type cpuplug_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.

120 SELinux requires files to have an extended attribute to define the file
121 type.
122 You can see the context of a file using the -Z option to ls
124 Policy governs the access confined processes have to these files.
126 SELinux cpuplug policy is very flexible allowing users to setup their
127 cpuplug processes in as secure a method as possible.
128 STANDARD FILE CONTEXT
130 SELinux defines the file context types for the cpuplug, if you wanted
132 to store files with these types in a diffent paths, you need to execute
133 the semanage command to sepecify alternate labeling and then use re‐
134 storecon to put the labels on disk.
135 semanage fcontext -a -t cpuplug_var_run_t '/srv/mycpuplug_con‐
137 tent(/.*)?'
138 restorecon -R -v /srv/mycpuplug_content
139 Note: SELinux often uses regular expressions to specify labels that
141 match multiple files.
142 The following file types are defined for cpuplug:
144 cpuplug_exec_t
148 - Set files with the cpuplug_exec_t type, if you want to transition an
150 executable to the cpuplug_t domain.
151 cpuplug_initrc_exec_t
155 - Set files with the cpuplug_initrc_exec_t type, if you want to transi‐
157 tion an executable to the cpuplug_initrc_t domain.
158 cpuplug_lock_t
162 - Set files with the cpuplug_lock_t type, if you want to treat the
164 files as cpuplug lock data, stored under the /var/lock directory
165 cpuplug_var_run_t
169 - Set files with the cpuplug_var_run_t type, if you want to store the
171 cpuplug files under the /run or /var/run directory.
172 Note: File context can be temporarily modified with the chcon command.
176 If you want to permanently change the file context you need to use the
177 semanage fcontext command. This will modify the SELinux labeling data‐
178 base. You will need to use restorecon to apply the labels.
179
182 semanage fcontext can also be used to manipulate default file context
183 mappings.
184 semanage permissive can also be used to manipulate whether or not a
186 process type is permissive.
187 semanage module can also be used to enable/disable/install/remove pol‐
189 icy modules.
190 semanage boolean can also be used to manipulate the booleans
192 system-config-selinux is a GUI tool available to customize SELinux pol‐
195 icy settings.
