NAME

6       fenced_selinux  -  Security  Enhanced  Linux Policy for the fenced pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  fenced  processes  via  flexible
11       mandatory access control.
12
13       The  fenced  processes  execute with the fenced_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep fenced_t
20
21
22

ENTRYPOINTS

24       The  fenced_t  SELinux  type  can be entered via the fenced_exec_t file
25       type.
26
27       The default entrypoint paths for the fenced_t domain are the following:
28
29       /usr/sbin/fenced,      /usr/sbin/fence_node,      /usr/sbin/fence_tool,
30       /usr/sbin/fence_scsi, /usr/sbin/fence_virtd, /usr/sbin/fence_sanlockd
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       fenced  policy  is  very  flexible allowing users to setup their fenced
40       processes in as secure a method as possible.
41
42       The following process types are defined for fenced:
43
44       fenced_t
45
46       Note: semanage permissive -a fenced_t can be used to make  the  process
47       type  fenced_t  permissive.  SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux  policy is customizable based on least access required.  fenced
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate the policy and run fenced with the tightest access possible.

FILE CONTEXTS

271       SELinux requires files to have an extended attribute to define the file
272       type.
273
274       You can see the context of a file using the -Z option to ls
275
276       Policy governs the access  confined  processes  have  to  these  files.
277       SELinux  fenced  policy  is very flexible allowing users to setup their
278       fenced processes in as secure a method as possible.
279
280       STANDARD FILE CONTEXT
281
282       SELinux defines the file context types for the fenced, if you wanted to
283       store  files  with  these types in a diffent paths, you need to execute
284       the semanage command  to  sepecify  alternate  labeling  and  then  use
285       restorecon to put the labels on disk.
286
287       semanage fcontext -a -t fenced_var_run_t '/srv/myfenced_content(/.*)?'
288       restorecon -R -v /srv/myfenced_content
289
290       Note:  SELinux  often  uses  regular expressions to specify labels that
291       match multiple files.
292
293       The following file types are defined for fenced:
294
295
296
297       fenced_exec_t
298
299       - Set files with the fenced_exec_t type, if you want to  transition  an
300       executable to the fenced_t domain.
301
302
303       Paths:
304            /usr/sbin/fenced,    /usr/sbin/fence_node,   /usr/sbin/fence_tool,
305            /usr/sbin/fence_scsi, /usr/sbin/fence_virtd,  /usr/sbin/fence_san‐
306            lockd
307
308
309       fenced_lock_t
310
311       - Set files with the fenced_lock_t type, if you want to treat the files
312       as fenced lock data, stored under the /var/lock directory
313
314
315
316       fenced_tmp_t
317
318       - Set files with the fenced_tmp_t type, if you  want  to  store  fenced
319       temporary files in the /tmp directories.
320
321
322
323       fenced_tmpfs_t
324
325       -  Set  files with the fenced_tmpfs_t type, if you want to store fenced
326       files on a tmpfs file system.
327
328
329
330       fenced_var_log_t
331
332       - Set files with the fenced_var_log_t type, if you want  to  treat  the
333       data  as  fenced var log data, usually stored under the /var/log direc‐
334       tory.
335
336
337
338       fenced_var_run_t
339
340       - Set files with the fenced_var_run_t type, if you want  to  store  the
341       fenced files under the /run or /var/run directory.
342
343
344       Paths:
345            /var/run/fence.*,   /var/run/cluster/fence_scsi.*,  /var/run/clus‐
346            ter/mpath.devices, /var/run/cluster/fenced_override
347
348
349       Note: File context can be temporarily modified with the chcon  command.
350       If  you want to permanently change the file context you need to use the
351       semanage fcontext command.  This will modify the SELinux labeling data‐
352       base.  You will need to use restorecon to apply the labels.
353
354

COMMANDS

356       semanage  fcontext  can also be used to manipulate default file context
357       mappings.
358
359       semanage permissive can also be used to manipulate  whether  or  not  a
360       process type is permissive.
361
362       semanage  module can also be used to enable/disable/install/remove pol‐
363       icy modules.
364
365       semanage boolean can also be used to manipulate the booleans
366
367
368       system-config-selinux is a GUI tool available to customize SELinux pol‐
369       icy settings.
