NAME

6       wdmd_selinux - Security Enhanced Linux Policy for the wdmd processes
7

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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.

MANAGED FILES

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

FILE CONTEXTS

219       SELinux requires files to have an extended attribute to define the file
220       type.
221
222       You can see the context of a file using the -Z option to ls
223
224       Policy  governs  the  access  confined  processes  have to these files.
225       SELinux wdmd policy is very flexible allowing users to setup their wdmd
226       processes in as secure a method as possible.
227
228       STANDARD FILE CONTEXT
229
230       SELinux  defines  the file context types for the wdmd, if you wanted to
231       store files with these types in a diffent paths, you  need  to  execute
232       the  semanage  command  to  sepecify  alternate  labeling  and then use
233       restorecon to put the labels on disk.
234
235       semanage fcontext -a -t wdmd_var_run_t '/srv/mywdmd_content(/.*)?'
236       restorecon -R -v /srv/mywdmd_content
237
238       Note: SELinux often uses regular expressions  to  specify  labels  that
239       match multiple files.
240
241       The following file types are defined for wdmd:
242
243
244
245       wdmd_exec_t
246
247       -  Set  files  with  the wdmd_exec_t type, if you want to transition an
248       executable to the wdmd_t domain.
249
250
251
252       wdmd_initrc_exec_t
253
254       - Set files with the wdmd_initrc_exec_t type, if you want to transition
255       an executable to the wdmd_initrc_t domain.
256
257
258
259       wdmd_tmpfs_t
260
261       - Set files with the wdmd_tmpfs_t type, if you want to store wdmd files
262       on a tmpfs file system.
263
264
265
266       wdmd_var_run_t
267
268       - Set files with the wdmd_var_run_t type, if you want to store the wdmd
269       files under the /run or /var/run directory.
270
271
272       Paths:
273            /var/run/wdmd(/.*)?, /var/run/checkquorum-timer
274
275
276       Note:  File context can be temporarily modified with the chcon command.
277       If you want to permanently change the file context you need to use  the
278       semanage fcontext command.  This will modify the SELinux labeling data‐
279       base.  You will need to use restorecon to apply the labels.
280
281

COMMANDS

283       semanage fcontext can also be used to manipulate default  file  context
284       mappings.
285
286       semanage  permissive  can  also  be used to manipulate whether or not a
287       process type is permissive.
288
289       semanage module can also be used to enable/disable/install/remove  pol‐
290       icy modules.
291
292       semanage boolean can also be used to manipulate the booleans
293
294
295       system-config-selinux is a GUI tool available to customize SELinux pol‐
296       icy settings.
