NAME

6       stapserver_selinux  - Security Enhanced Linux Policy for the stapserver
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the stapserver processes  via  flexible
11       mandatory access control.
12
13       The  stapserver  processes  execute with the stapserver_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 stapserver_t
20
21
22

ENTRYPOINTS

24       The  stapserver_t SELinux type can be entered via the stapserver_exec_t
25       file type.
26
27       The default entrypoint paths for the stapserver_t domain are  the  fol‐
28       lowing:
29
30       /usr/bin/stap-server
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       stapserver  policy  is  very  flexible  allowing  users  to setup their
40       stapserver processes in as secure a method as possible.
41
42       The following process types are defined for stapserver:
43
44       stapserver_t
45
46       Note: semanage permissive -a stapserver_t  can  be  used  to  make  the
47       process  type  stapserver_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       stapserver policy is extremely flexible and has several  booleans  that
55       allow you to manipulate the policy and run stapserver with the tightest
56       access possible.

FILE CONTEXTS

227       SELinux requires files to have an extended attribute to define the file
228       type.
229
230       You can see the context of a file using the -Z option to ls
231
232       Policy  governs  the  access  confined  processes  have to these files.
233       SELinux stapserver policy is very  flexible  allowing  users  to  setup
234       their stapserver processes in as secure a method as possible.
235
236       STANDARD FILE CONTEXT
237
238       SELinux  defines  the  file  context  types  for the stapserver, if you
239       wanted to store files with these types in a diffent paths, you need  to
240       execute  the  semanage  command to sepecify alternate labeling and then
241       use restorecon to put the labels on disk.
242
243       semanage fcontext -a  -t  stapserver_var_run_t  '/srv/mystapserver_con‐
244       tent(/.*)?'
245       restorecon -R -v /srv/mystapserver_content
246
247       Note:  SELinux  often  uses  regular expressions to specify labels that
248       match multiple files.
249
250       The following file types are defined for stapserver:
251
252
253
254       stapserver_exec_t
255
256       - Set files with the stapserver_exec_t type, if you want to  transition
257       an executable to the stapserver_t domain.
258
259
260
261       stapserver_log_t
262
263       -  Set  files  with the stapserver_log_t type, if you want to treat the
264       data as stapserver log data, usually stored under the  /var/log  direc‐
265       tory.
266
267
268
269       stapserver_tmp_t
270
271       -  Set  files  with  the  stapserver_tmp_t  type,  if you want to store
272       stapserver temporary files in the /tmp directories.
273
274
275
276       stapserver_var_lib_t
277
278       - Set files with the stapserver_var_lib_t type, if you  want  to  store
279       the stapserver files under the /var/lib directory.
280
281
282
283       stapserver_var_run_t
284
285       -  Set  files  with the stapserver_var_run_t type, if you want to store
286       the stapserver 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.
