NAME

6       automount_selinux  -  Security  Enhanced Linux Policy for the automount
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

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

MANAGED FILES

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

FILE CONTEXTS

244       SELinux requires files to have an extended attribute to define the file
245       type.
246
247       You can see the context of a file using the -Z option to ls
248
249       Policy governs the access  confined  processes  have  to  these  files.
250       SELinux automount policy is very flexible allowing users to setup their
251       automount processes in as secure a method as possible.
252
253       STANDARD FILE CONTEXT
254
255       SELinux defines the file context types for the automount, if you wanted
256       to store files with these types in a diffent paths, you need to execute
257       the semanage command  to  sepecify  alternate  labeling  and  then  use
258       restorecon to put the labels on disk.
259
260       semanage  fcontext  -a  -t  automount_var_run_t  '/srv/myautomount_con‐
261       tent(/.*)?'
262       restorecon -R -v /srv/myautomount_content
263
264       Note: SELinux often uses regular expressions  to  specify  labels  that
265       match multiple files.
266
267       The following file types are defined for automount:
268
269
270
271       automount_exec_t
272
273       -  Set  files with the automount_exec_t type, if you want to transition
274       an executable to the automount_t domain.
275
276
277       Paths:
278            /usr/sbin/automount, /etc/apm/event.d/autofs
279
280
281       automount_initrc_exec_t
282
283       - Set files with the automount_initrc_exec_t type, if you want to tran‐
284       sition an executable to the automount_initrc_t domain.
285
286
287
288       automount_keytab_t
289
290       -  Set files with the automount_keytab_t type, if you want to treat the
291       files as kerberos keytab files.
292
293
294
295       automount_lock_t
296
297       - Set files with the automount_lock_t type, if you want  to  treat  the
298       files as automount lock data, stored under the /var/lock directory
299
300
301
302       automount_tmp_t
303
304       -  Set  files with the automount_tmp_t type, if you want to store auto‐
305       mount temporary files in the /tmp directories.
306
307
308
309       automount_unit_file_t
310
311       - Set files with the automount_unit_file_t type, if you want  to  treat
312       the files as automount unit content.
313
314
315
316       automount_var_run_t
317
318       - Set files with the automount_var_run_t type, if you want to store the
319       automount files under the /run or /var/run directory.
320
321
322
323       Note: File context can be temporarily modified with the chcon  command.
324       If  you want to permanently change the file context you need to use the
325       semanage fcontext command.  This will modify the SELinux labeling data‐
326       base.  You will need to use restorecon to apply the labels.
327
328

COMMANDS

330       semanage  fcontext  can also be used to manipulate default file context
331       mappings.
332
333       semanage permissive can also be used to manipulate  whether  or  not  a
334       process type is permissive.
335
336       semanage  module can also be used to enable/disable/install/remove pol‐
337       icy modules.
338
339       semanage boolean can also be used to manipulate the booleans
340
341
342       system-config-selinux is a GUI tool available to customize SELinux pol‐
343       icy settings.
