6 cgconfig_selinux - Security Enhanced Linux Policy for the cgconfig pro‐
7 cesses
8
10 Security-Enhanced Linux secures the cgconfig processes via flexible
11 mandatory access control.
12 The cgconfig processes execute with the cgconfig_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep cgconfig_t
20
24 The cgconfig_t SELinux type can be entered via the cgconfig_exec_t file
25 type.
26 The default entrypoint paths for the cgconfig_t domain are the follow‐
28 ing:
29 /sbin/cgconfigparser
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 cgconfig policy is very flexible allowing users to setup their cgconfig
40 processes in as secure a method as possible.
41 The following process types are defined for cgconfig:
43 cgconfig_t
45 Note: semanage permissive -a cgconfig_t can be used to make the process
47 type cgconfig_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. cgcon‐
54 fig policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run cgconfig with the tightest access
56 possible.

129 If you want to enable reading of urandom for all domains, you must turn
133 on the global_ssp boolean. Disabled by default.
134 setsebool -P global_ssp 1

140 turn on the init_upstart boolean. Enabled by default.
141 setsebool -P init_upstart 1
143 If you want to allow confined applications to use nscd shared memory,
147 you must turn on the nscd_use_shm boolean. Enabled by default.
148 setsebool -P nscd_use_shm 1

154 The SELinux process type cgconfig_t can manage files labeled with the
155 following file types. The paths listed are the default paths for these
156 file types. Note the processes UID still need to have DAC permissions.

221 SELinux requires files to have an extended attribute to define the file
222 type.
223 You can see the context of a file using the -Z option to ls
225 Policy governs the access confined processes have to these files.
227 SELinux cgconfig policy is very flexible allowing users to setup their
228 cgconfig processes in as secure a method as possible.
229 STANDARD FILE CONTEXT
231 SELinux defines the file context types for the cgconfig, if you wanted
233 to store files with these types in a diffent paths, you need to execute
234 the semanage command to sepecify alternate labeling and then use
235 restorecon to put the labels on disk.
236 semanage fcontext -a -t cgconfig_etc_t '/srv/mycgconfig_content(/.*)?'
238 restorecon -R -v /srv/mycgconfig_content
239 Note: SELinux often uses regular expressions to specify labels that
241 match multiple files.
242 The following file types are defined for cgconfig:
244 cgconfig_etc_t
248 - Set files with the cgconfig_etc_t type, if you want to store cgconfig
250 files in the /etc directories.
251 Paths:
254 /etc/cgconfig.conf, /etc/sysconfig/cgconfig
255 cgconfig_exec_t
258 - Set files with the cgconfig_exec_t type, if you want to transition an
260 executable to the cgconfig_t domain.
261 cgconfig_initrc_exec_t
265 - Set files with the cgconfig_initrc_exec_t type, if you want to tran‐
267 sition an executable to the cgconfig_initrc_t domain.
268 Note: File context can be temporarily modified with the chcon command.
272 If you want to permanently change the file context you need to use the
273 semanage fcontext command. This will modify the SELinux labeling data‐
274 base. You will need to use restorecon to apply the labels.
275
278 semanage fcontext can also be used to manipulate default file context
279 mappings.
280 semanage permissive can also be used to manipulate whether or not a
282 process type is permissive.
283 semanage module can also be used to enable/disable/install/remove pol‐
285 icy modules.
286 semanage boolean can also be used to manipulate the booleans
288 system-config-selinux is a GUI tool available to customize SELinux pol‐
291 icy settings.
