6 cgred_selinux - Security Enhanced Linux Policy for the cgred processes
7
9 Security-Enhanced Linux secures the cgred processes via flexible manda‐
10 tory access control.
11 The cgred processes execute with the cgred_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep cgred_t
19
23 The cgred_t SELinux type can be entered via the cgred_exec_t file type.
24 The default entrypoint paths for the cgred_t domain are the following:
26 /sbin/cgrulesengd, /usr/sbin/cgrulesengd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 cgred policy is very flexible allowing users to setup their cgred pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for cgred:
40 cgred_t
42 Note: semanage permissive -a cgred_t can be used to make the process
44 type cgred_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. cgred
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run cgred with the tightest access possible.
53 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58 setsebool -P fips_mode 1
60 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65 setsebool -P nis_enabled 1
67
71 The SELinux process type cgred_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.

131 SELinux requires files to have an extended attribute to define the file
132 type.
133 You can see the context of a file using the -Z option to ls
135 Policy governs the access confined processes have to these files.
137 SELinux cgred policy is very flexible allowing users to setup their
138 cgred processes in as secure a method as possible.
139 STANDARD FILE CONTEXT
141 SELinux defines the file context types for the cgred, if you wanted to
143 store files with these types in a diffent paths, you need to execute
144 the semanage command to specify alternate labeling and then use re‐
145 storecon to put the labels on disk.
146 semanage fcontext -a -t cgred_var_run_t '/srv/mycgred_content(/.*)?'
148 restorecon -R -v /srv/mycgred_content
149 Note: SELinux often uses regular expressions to specify labels that
151 match multiple files.
152 The following file types are defined for cgred:
154 cgred_exec_t
158 - Set files with the cgred_exec_t type, if you want to transition an
160 executable to the cgred_t domain.
161 Paths:
164 /sbin/cgrulesengd, /usr/sbin/cgrulesengd
165 cgred_initrc_exec_t
168 - Set files with the cgred_initrc_exec_t type, if you want to transi‐
170 tion an executable to the cgred_initrc_t domain.
171 cgred_log_t
175 - Set files with the cgred_log_t type, if you want to treat the data as
177 cgred log data, usually stored under the /var/log directory.
178 cgred_var_run_t
182 - Set files with the cgred_var_run_t type, if you want to store the
184 cgred files under the /run or /var/run directory.
185 Note: File context can be temporarily modified with the chcon command.
189 If you want to permanently change the file context you need to use the
190 semanage fcontext command. This will modify the SELinux labeling data‐
191 base. You will need to use restorecon to apply the labels.
192
195 semanage fcontext can also be used to manipulate default file context
196 mappings.
197 semanage permissive can also be used to manipulate whether or not a
199 process type is permissive.
200 semanage module can also be used to enable/disable/install/remove pol‐
202 icy modules.
203 semanage boolean can also be used to manipulate the booleans
205 system-config-selinux is a GUI tool available to customize SELinux pol‐
208 icy settings.
