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_t, winbind_helper_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

306       SELinux requires files to have an extended attribute to define the file
307       type.
308
309       You can see the context of a file using the -Z option to ls
310
311       Policy  governs  the  access  confined  processes  have to these files.
312       SELinux winbind policy is very flexible allowing users to  setup  their
313       winbind processes in as secure a method as possible.
314
315       STANDARD FILE CONTEXT
316
317       SELinux  defines  the file context types for the winbind, if you wanted
318       to store files with these types in a diffent paths, you need to execute
319       the  semanage  command  to  sepecify  alternate  labeling  and then use
320       restorecon to put the labels on disk.
321
322       semanage  fcontext   -a   -t   winbind_var_run_t   '/srv/mywinbind_con‐
323       tent(/.*)?'
324       restorecon -R -v /srv/mywinbind_content
325
326       Note:  SELinux  often  uses  regular expressions to specify labels that
327       match multiple files.
328
329       The following file types are defined for winbind:
330
331
332
333       winbind_exec_t
334
335       - Set files with the winbind_exec_t type, if you want to transition  an
336       executable to the winbind_t domain.
337
338
339
340       winbind_helper_exec_t
341
342       - Set files with the winbind_helper_exec_t type, if you want to transi‐
343       tion an executable to the winbind_helper_t domain.
344
345
346
347       winbind_log_t
348
349       - Set files with the winbind_log_t type, if you want to treat the  data
350       as winbind log data, usually stored under the /var/log directory.
351
352
353
354       winbind_var_run_t
355
356       -  Set  files with the winbind_var_run_t type, if you want to store the
357       winbind files under the /run or /var/run directory.
358
359
360       Paths:
361            /var/run/winbindd(/.*)?,            /var/run/samba/winbindd(/.*)?,
362            /var/lib/samba/winbindd_privileged(/.*)?,    /var/cache/samba/win‐
363            bindd_privileged(/.*)?
364
365
366       Note: File context can be temporarily modified with the chcon  command.
367       If  you want to permanently change the file context you need to use the
368       semanage fcontext command.  This will modify the SELinux labeling data‐
369       base.  You will need to use restorecon to apply the labels.
370
371

COMMANDS

373       semanage  fcontext  can also be used to manipulate default file context
374       mappings.
375
376       semanage permissive can also be used to manipulate  whether  or  not  a
377       process type is permissive.
378
379       semanage  module can also be used to enable/disable/install/remove pol‐
380       icy modules.
381
382       semanage boolean can also be used to manipulate the booleans
383
384
385       system-config-selinux is a GUI tool available to customize SELinux pol‐
386       icy settings.
