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, /usr/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.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.

128 must turn on the domain_kernel_load_modules boolean. Disabled by
129 default.
130 setsebool -P domain_kernel_load_modules 1
132 If you want to allow all domains to execute in fips_mode, you must turn
136 on the fips_mode boolean. Enabled by default.
137 setsebool -P fips_mode 1
139 If you want to enable reading of urandom for all domains, you must turn
143 on the global_ssp boolean. Disabled by default.
144 setsebool -P global_ssp 1
146 If you want to allow confined applications to run with kerberos, you
150 must turn on the kerberos_enabled boolean. Enabled by default.
151 setsebool -P kerberos_enabled 1
153 If you want to allow system to run with NIS, you must turn on the
157 nis_enabled boolean. Disabled by default.
158 setsebool -P nis_enabled 1
160 If you want to allow confined applications to use nscd shared memory,
164 you must turn on the nscd_use_shm boolean. Disabled by default.
165 setsebool -P nscd_use_shm 1

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

216 SELinux requires files to have an extended attribute to define the file
217 type.
218 You can see the context of a file using the -Z option to ls
220 Policy governs the access confined processes have to these files.
222 SELinux cgconfig policy is very flexible allowing users to setup their
223 cgconfig processes in as secure a method as possible.
224 STANDARD FILE CONTEXT
226 SELinux defines the file context types for the cgconfig, if you wanted
228 to store files with these types in a diffent paths, you need to execute
229 the semanage command to sepecify alternate labeling and then use
230 restorecon to put the labels on disk.
231 semanage fcontext -a -t cgconfig_etc_t '/srv/mycgconfig_content(/.*)?'
233 restorecon -R -v /srv/mycgconfig_content
234 Note: SELinux often uses regular expressions to specify labels that
236 match multiple files.
237 The following file types are defined for cgconfig:
239 cgconfig_etc_t
243 - Set files with the cgconfig_etc_t type, if you want to store cgconfig
245 files in the /etc directories.
246 Paths:
249 /etc/cgconfig.conf, /etc/sysconfig/cgconfig
250 cgconfig_exec_t
253 - Set files with the cgconfig_exec_t type, if you want to transition an
255 executable to the cgconfig_t domain.
256 Paths:
259 /sbin/cgconfigparser, /usr/sbin/cgconfigparser
260 cgconfig_initrc_exec_t
263 - Set files with the cgconfig_initrc_exec_t type, if you want to tran‐
265 sition an executable to the cgconfig_initrc_t domain.
266 Note: File context can be temporarily modified with the chcon command.
270 If you want to permanently change the file context you need to use the
271 semanage fcontext command. This will modify the SELinux labeling data‐
272 base. You will need to use restorecon to apply the labels.
273
276 semanage fcontext can also be used to manipulate default file context
277 mappings.
278 semanage permissive can also be used to manipulate whether or not a
280 process type is permissive.
281 semanage module can also be used to enable/disable/install/remove pol‐
283 icy modules.
284 semanage boolean can also be used to manipulate the booleans
286 system-config-selinux is a GUI tool available to customize SELinux pol‐
289 icy settings.
