6 wdmd_selinux - Security Enhanced Linux Policy for the wdmd processes
7
9 Security-Enhanced Linux secures the wdmd processes via flexible manda‐
10 tory access control.
11
12 The wdmd processes execute with the wdmd_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep wdmd_t
19
20
21
23 The wdmd_t SELinux type can be entered via the wdmd_exec_t file type.
24
25 The default entrypoint paths for the wdmd_t domain are the following:
26
27 /usr/sbin/wdmd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 wdmd policy is very flexible allowing users to setup their wdmd pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for wdmd:
40
41 wdmd_t
42
43 Note: semanage permissive -a wdmd_t can be used to make the process
44 type wdmd_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. wdmd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run wdmd with the tightest access possible.

150 The SELinux process type wdmd_t can manage files labeled with the fol‐
151 lowing file types. The paths listed are the default paths for these
152 file types. Note the processes UID still need to have DAC permissions.

225 SELinux requires files to have an extended attribute to define the file
226 type.
227
228 You can see the context of a file using the -Z option to ls
229
230 Policy governs the access confined processes have to these files.
231 SELinux wdmd policy is very flexible allowing users to setup their wdmd
232 processes in as secure a method as possible.
233
234 STANDARD FILE CONTEXT
235
236 SELinux defines the file context types for the wdmd, if you wanted to
237 store files with these types in a diffent paths, you need to execute
238 the semanage command to sepecify alternate labeling and then use
239 restorecon to put the labels on disk.
240
241 semanage fcontext -a -t wdmd_var_run_t '/srv/mywdmd_content(/.*)?'
242 restorecon -R -v /srv/mywdmd_content
243
244 Note: SELinux often uses regular expressions to specify labels that
245 match multiple files.
246
247 The following file types are defined for wdmd:
248
249
250
251 wdmd_exec_t
252
253 - Set files with the wdmd_exec_t type, if you want to transition an
254 executable to the wdmd_t domain.
255
256
257
258 wdmd_initrc_exec_t
259
260 - Set files with the wdmd_initrc_exec_t type, if you want to transition
261 an executable to the wdmd_initrc_t domain.
262
263
264
265 wdmd_tmpfs_t
266
267 - Set files with the wdmd_tmpfs_t type, if you want to store wdmd files
268 on a tmpfs file system.
269
270
271
272 wdmd_var_run_t
273
274 - Set files with the wdmd_var_run_t type, if you want to store the wdmd
275 files under the /run or /var/run directory.
276
277
278 Paths:
279 /var/run/wdmd(/.*)?, /var/run/checkquorum-timer, /var/run/clus‐
280 ter/checkquorum-timer
281
282
283 Note: File context can be temporarily modified with the chcon command.
284 If you want to permanently change the file context you need to use the
285 semanage fcontext command. This will modify the SELinux labeling data‐
286 base. You will need to use restorecon to apply the labels.
287
288
290 semanage fcontext can also be used to manipulate default file context
291 mappings.
292
293 semanage permissive can also be used to manipulate whether or not a
294 process type is permissive.
295
296 semanage module can also be used to enable/disable/install/remove pol‐
297 icy modules.
298
299 semanage boolean can also be used to manipulate the booleans
300
301
302 system-config-selinux is a GUI tool available to customize SELinux pol‐
303 icy settings.
