NAME

6       winbind_selinux  -  Security Enhanced Linux Policy for the winbind pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  winbind  processes  via  flexible
11       mandatory access control.
12
13       The  winbind processes execute with the winbind_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 winbind_t
20
21
22

ENTRYPOINTS

24       The  winbind_t  SELinux type can be entered via the winbind_exec_t file
25       type.
26
27       The default entrypoint paths for the winbind_t domain are  the  follow‐
28       ing:
29
30       /usr/sbin/winbindd
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       winbind  policy  is very flexible allowing users to setup their winbind
40       processes in as secure a method as possible.
41
42       The following process types are defined for winbind:
43
44       winbind_helper_t, winbind_t
45
46       Note: semanage permissive -a winbind_t can be used to make the  process
47       type  winbind_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.  winbind
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run winbind with the tightest access possi‐
56       ble.

FILE CONTEXTS

294       SELinux requires files to have an extended attribute to define the file
295       type.
296
297       You can see the context of a file using the -Z option to ls
298
299       Policy governs the access  confined  processes  have  to  these  files.
300       SELinux  winbind  policy is very flexible allowing users to setup their
301       winbind processes in as secure a method as possible.
302
303       STANDARD FILE CONTEXT
304
305       SELinux defines the file context types for the winbind, if  you  wanted
306       to store files with these types in a diffent paths, you need to execute
307       the semanage command  to  sepecify  alternate  labeling  and  then  use
308       restorecon to put the labels on disk.
309
310       semanage   fcontext   -a   -t   winbind_var_run_t  '/srv/mywinbind_con‐
311       tent(/.*)?'
312       restorecon -R -v /srv/mywinbind_content
313
314       Note: SELinux often uses regular expressions  to  specify  labels  that
315       match multiple files.
316
317       The following file types are defined for winbind:
318
319
320
321       winbind_exec_t
322
323       -  Set files with the winbind_exec_t type, if you want to transition an
324       executable to the winbind_t domain.
325
326
327
328       winbind_helper_exec_t
329
330       - Set files with the winbind_helper_exec_t type, if you want to transi‐
331       tion an executable to the winbind_helper_t domain.
332
333
334
335       winbind_log_t
336
337       -  Set files with the winbind_log_t type, if you want to treat the data
338       as winbind log data, usually stored under the /var/log directory.
339
340
341
342       winbind_var_run_t
343
344       - Set files with the winbind_var_run_t type, if you want to  store  the
345       winbind files under the /run or /var/run directory.
346
347
348       Paths:
349            /var/run/winbindd(/.*)?, /var/lib/samba/winbindd_privileged(/.*)?,
350            /var/cache/samba/winbindd_privileged(/.*)?
351
352
353       Note: File context can be temporarily modified with the chcon  command.
354       If  you want to permanently change the file context you need to use the
355       semanage fcontext command.  This will modify the SELinux labeling data‐
356       base.  You will need to use restorecon to apply the labels.
357
358

COMMANDS

360       semanage  fcontext  can also be used to manipulate default file context
361       mappings.
362
363       semanage permissive can also be used to manipulate  whether  or  not  a
364       process type is permissive.
365
366       semanage  module can also be used to enable/disable/install/remove pol‐
367       icy modules.
368
369       semanage boolean can also be used to manipulate the booleans
370
371
372       system-config-selinux is a GUI tool available to customize SELinux pol‐
373       icy settings.
