6 dlm_controld_selinux - Security Enhanced Linux Policy for the dlm_con‐
7 trold processes
8
10 Security-Enhanced Linux secures the dlm_controld processes via flexible
11 mandatory access control.
12 The dlm_controld processes execute with the dlm_controld_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep dlm_controld_t
20
24 The dlm_controld_t SELinux type can be entered via the dlm_con‐
25 trold_exec_t file type.
26 The default entrypoint paths for the dlm_controld_t domain are the fol‐
28 lowing:
29 /usr/sbin/dlm_controld
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 dlm_controld policy is very flexible allowing users to setup their
40 dlm_controld processes in as secure a method as possible.
41 The following process types are defined for dlm_controld:
43 dlm_controld_t
45 Note: semanage permissive -a dlm_controld_t can be used to make the
47 process type dlm_controld_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.
54 dlm_controld policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run dlm_controld with the tight‐
56 est access possible.

162 The SELinux process type dlm_controld_t can manage files labeled with
163 the following file types. The paths listed are the default paths for
164 these file types. Note the processes UID still need to have DAC per‐
165 missions.

243 SELinux requires files to have an extended attribute to define the file
244 type.
245 You can see the context of a file using the -Z option to ls
247 Policy governs the access confined processes have to these files.
249 SELinux dlm_controld policy is very flexible allowing users to setup
250 their dlm_controld processes in as secure a method as possible.
251 STANDARD FILE CONTEXT
253 SELinux defines the file context types for the dlm_controld, if you
255 wanted to store files with these types in a diffent paths, you need to
256 execute the semanage command to sepecify alternate labeling and then
257 use restorecon to put the labels on disk.
258 semanage fcontext -a -t dlm_controld_var_run_t '/srv/mydlm_con‐
260 trold_content(/.*)?'
261 restorecon -R -v /srv/mydlm_controld_content
262 Note: SELinux often uses regular expressions to specify labels that
264 match multiple files.
265 The following file types are defined for dlm_controld:
267 dlm_controld_exec_t
271 - Set files with the dlm_controld_exec_t type, if you want to transi‐
273 tion an executable to the dlm_controld_t domain.
274 dlm_controld_tmpfs_t
278 - Set files with the dlm_controld_tmpfs_t type, if you want to store
280 dlm controld files on a tmpfs file system.
281 dlm_controld_var_log_t
285 - Set files with the dlm_controld_var_log_t type, if you want to treat
287 the data as dlm controld var log data, usually stored under the
288 /var/log directory.
289 dlm_controld_var_run_t
293 - Set files with the dlm_controld_var_run_t type, if you want to store
295 the dlm controld files under the /run or /var/run directory.
296 Note: File context can be temporarily modified with the chcon command.
300 If you want to permanently change the file context you need to use the
301 semanage fcontext command. This will modify the SELinux labeling data‐
302 base. You will need to use restorecon to apply the labels.
303
306 semanage fcontext can also be used to manipulate default file context
307 mappings.
308 semanage permissive can also be used to manipulate whether or not a
310 process type is permissive.
311 semanage module can also be used to enable/disable/install/remove pol‐
313 icy modules.
314 semanage boolean can also be used to manipulate the booleans
316 system-config-selinux is a GUI tool available to customize SELinux pol‐
319 icy settings.
