NAME

6       keepalived_selinux  - Security Enhanced Linux Policy for the keepalived
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  keepalived_t SELinux type can be entered via the keepalived_exec_t
25       file type.
26
27       The default entrypoint paths for the keepalived_t domain are  the  fol‐
28       lowing:
29
30       /usr/sbin/keepalived
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       keepalived  policy  is  very  flexible  allowing  users  to setup their
40       keepalived processes in as secure a method as possible.
41
42       The following process types are defined for keepalived:
43
44       keepalived_t, keepalived_unconfined_script_t
45
46       Note: semanage permissive -a keepalived_t  can  be  used  to  make  the
47       process  type  keepalived_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

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

MANAGED FILES

161       The SELinux process type keepalived_t can manage files labeled with the
162       following file types.  The paths listed are the default paths for these
163       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

237       SELinux requires files to have an extended attribute to define the file
238       type.
239
240       You can see the context of a file using the -Z option to ls
241
242       Policy  governs  the  access  confined  processes  have to these files.
243       SELinux keepalived policy is very  flexible  allowing  users  to  setup
244       their keepalived processes in as secure a method as possible.
245
246       STANDARD FILE CONTEXT
247
248       SELinux  defines  the  file  context  types  for the keepalived, if you
249       wanted to store files with these types in a diffent paths, you need  to
250       execute  the  semanage  command to sepecify alternate labeling and then
251       use restorecon to put the labels on disk.
252
253       semanage fcontext -a  -t  keepalived_var_run_t  '/srv/mykeepalived_con‐
254       tent(/.*)?'
255       restorecon -R -v /srv/mykeepalived_content
256
257       Note:  SELinux  often  uses  regular expressions to specify labels that
258       match multiple files.
259
260       The following file types are defined for keepalived:
261
262
263
264       keepalived_exec_t
265
266       - Set files with the keepalived_exec_t type, if you want to  transition
267       an executable to the keepalived_t domain.
268
269
270
271       keepalived_initrc_exec_t
272
273       -  Set  files  with  the  keepalived_initrc_exec_t type, if you want to
274       transition an executable to the keepalived_initrc_t domain.
275
276
277
278       keepalived_unconfined_script_exec_t
279
280       - Set files with the keepalived_unconfined_script_exec_t type,  if  you
281       want  to transition an executable to the keepalived_unconfined_script_t
282       domain.
283
284
285
286       keepalived_var_run_t
287
288       - Set files with the keepalived_var_run_t type, if you  want  to  store
289       the keepalived files under the /run or /var/run directory.
290
291
292
293       Note:  File context can be temporarily modified with the chcon command.
294       If you want to permanently change the file context you need to use  the
295       semanage fcontext command.  This will modify the SELinux labeling data‐
296       base.  You will need to use restorecon to apply the labels.
297
298

COMMANDS

300       semanage fcontext can also be used to manipulate default  file  context
301       mappings.
302
303       semanage  permissive  can  also  be used to manipulate whether or not a
304       process type is permissive.
305
306       semanage module can also be used to enable/disable/install/remove  pol‐
307       icy modules.
308
309       semanage boolean can also be used to manipulate the booleans
310
311
312       system-config-selinux is a GUI tool available to customize SELinux pol‐
313       icy settings.
