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.
57
58

MANAGED FILES

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

FILE CONTEXTS

234       SELinux requires files to have an extended attribute to define the file
235       type.
236
237       You can see the context of a file using the -Z option to ls
238
239       Policy  governs  the  access  confined  processes  have to these files.
240       SELinux keepalived policy is very  flexible  allowing  users  to  setup
241       their keepalived processes in as secure a method as possible.
242
243       STANDARD FILE CONTEXT
244
245       SELinux  defines  the  file  context  types  for the keepalived, if you
246       wanted to store files with these types in a diffent paths, you need  to
247       execute  the  semanage  command to sepecify alternate labeling and then
248       use restorecon to put the labels on disk.
249
250       semanage fcontext -a  -t  keepalived_var_run_t  '/srv/mykeepalived_con‐
251       tent(/.*)?'
252       restorecon -R -v /srv/mykeepalived_content
253
254       Note:  SELinux  often  uses  regular expressions to specify labels that
255       match multiple files.
256
257       The following file types are defined for keepalived:
258
259
260
261       keepalived_exec_t
262
263       - Set files with the keepalived_exec_t type, if you want to  transition
264       an executable to the keepalived_t domain.
265
266
267
268       keepalived_unconfined_script_exec_t
269
270       -  Set  files with the keepalived_unconfined_script_exec_t type, if you
271       want to transition an executable to the  keepalived_unconfined_script_t
272       domain.
273
274
275
276       keepalived_unit_file_t
277
278       -  Set files with the keepalived_unit_file_t type, if you want to treat
279       the files as keepalived unit content.
280
281
282
283       keepalived_var_run_t
284
285       - Set files with the keepalived_var_run_t type, if you  want  to  store
286       the keepalived files under the /run or /var/run directory.
287
288
289
290       Note:  File context can be temporarily modified with the chcon command.
291       If you want to permanently change the file context you need to use  the
292       semanage fcontext command.  This will modify the SELinux labeling data‐
293       base.  You will need to use restorecon to apply the labels.
294
295

COMMANDS

297       semanage fcontext can also be used to manipulate default  file  context
298       mappings.
299
300       semanage  permissive  can  also  be used to manipulate whether or not a
301       process type is permissive.
302
303       semanage module can also be used to enable/disable/install/remove  pol‐
304       icy modules.
305
306       semanage boolean can also be used to manipulate the booleans
307
308
309       system-config-selinux is a GUI tool available to customize SELinux pol‐
310       icy settings.
