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.

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

245 SELinux requires files to have an extended attribute to define the file
246 type.
247 You can see the context of a file using the -Z option to ls
249 Policy governs the access confined processes have to these files.
251 SELinux dlm_controld policy is very flexible allowing users to setup
252 their dlm_controld processes in as secure a method as possible.
253 EQUIVALENCE DIRECTORIES
255 dlm_controld policy stores data with multiple different file context
258 types under the /var/run/dlm_controld directory. If you would like to
259 store the data in a different directory you can use the semanage com‐
260 mand to create an equivalence mapping. If you wanted to store this
261 data under the /srv dirctory you would execute the following command:
262 semanage fcontext -a -e /var/run/dlm_controld /srv/dlm_controld
264 restorecon -R -v /srv/dlm_controld
265 STANDARD FILE CONTEXT
267 SELinux defines the file context types for the dlm_controld, if you
269 wanted to store files with these types in a diffent paths, you need to
270 execute the semanage command to sepecify alternate labeling and then
271 use restorecon to put the labels on disk.
272 semanage fcontext -a -t dlm_controld_var_run_t '/srv/mydlm_con‐
274 trold_content(/.*)?'
275 restorecon -R -v /srv/mydlm_controld_content
276 Note: SELinux often uses regular expressions to specify labels that
278 match multiple files.
279 The following file types are defined for dlm_controld:
281 dlm_controld_exec_t
285 - Set files with the dlm_controld_exec_t type, if you want to transi‐
287 tion an executable to the dlm_controld_t domain.
288 dlm_controld_initrc_exec_t
292 - Set files with the dlm_controld_initrc_exec_t type, if you want to
294 transition an executable to the dlm_controld_initrc_t domain.
295 dlm_controld_tmpfs_t
299 - Set files with the dlm_controld_tmpfs_t type, if you want to store
301 dlm controld files on a tmpfs file system.
302 dlm_controld_var_log_t
306 - Set files with the dlm_controld_var_log_t type, if you want to treat
308 the data as dlm controld var log data, usually stored under the
309 /var/log directory.
310 Paths:
313 /var/log/dlm_controld(/.*)?, /var/log/cluster/dlm_controld.log.*
314 dlm_controld_var_run_t
317 - Set files with the dlm_controld_var_run_t type, if you want to store
319 the dlm controld files under the /run or /var/run directory.
320 Paths:
323 /var/run/dlm_controld(/.*)?, /var/run/dlm_controld.pid
324 Note: File context can be temporarily modified with the chcon command.
327 If you want to permanently change the file context you need to use the
328 semanage fcontext command. This will modify the SELinux labeling data‐
329 base. You will need to use restorecon to apply the labels.
330
333 semanage fcontext can also be used to manipulate default file context
334 mappings.
335 semanage permissive can also be used to manipulate whether or not a
337 process type is permissive.
338 semanage module can also be used to enable/disable/install/remove pol‐
340 icy modules.
341 semanage boolean can also be used to manipulate the booleans
343 system-config-selinux is a GUI tool available to customize SELinux pol‐
346 icy settings.
