NAME

6       openvpn_selinux  -  Security Enhanced Linux Policy for the openvpn pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  openvpn  processes  via  flexible
11       mandatory access control.
12
13       The  openvpn processes execute with the openvpn_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 openvpn_t
20
21
22

ENTRYPOINTS

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

PORT TYPES

182       SELinux defines port types to represent TCP and UDP ports.
183
184       You  can  see  the  types associated with a port by using the following
185       command:
186
187       semanage port -l
188
189
190       Policy governs the access  confined  processes  have  to  these  ports.
191       SELinux  openvpn  policy is very flexible allowing users to setup their
192       openvpn processes in as secure a method as possible.
193
194       The following port types are defined for openvpn:
195
196
197       openvpn_port_t
198
199
200
201       Default Defined Ports:
202                 tcp 1194
203                 udp 1194
204

MANAGED FILES

206       The SELinux process type openvpn_t can manage files  labeled  with  the
207       following file types.  The paths listed are the default paths for these
208       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

329       SELinux requires files to have an extended attribute to define the file
330       type.
331
332       You can see the context of a file using the -Z option to ls
333
334       Policy  governs  the  access  confined  processes  have to these files.
335       SELinux openvpn policy is very flexible allowing users to  setup  their
336       openvpn processes in as secure a method as possible.
337
338       STANDARD FILE CONTEXT
339
340       SELinux  defines  the file context types for the openvpn, if you wanted
341       to store files with these types in a diffent paths, you need to execute
342       the  semanage  command  to  sepecify  alternate  labeling  and then use
343       restorecon to put the labels on disk.
344
345       semanage  fcontext   -a   -t   openvpn_var_run_t   '/srv/myopenvpn_con‐
346       tent(/.*)?'
347       restorecon -R -v /srv/myopenvpn_content
348
349       Note:  SELinux  often  uses  regular expressions to specify labels that
350       match multiple files.
351
352       The following file types are defined for openvpn:
353
354
355
356       openvpn_etc_rw_t
357
358       - Set files with the openvpn_etc_rw_t type, if you want  to  treat  the
359       files as openvpn etc read/write content.
360
361
362
363       openvpn_etc_t
364
365       -  Set  files with the openvpn_etc_t type, if you want to store openvpn
366       files in the /etc directories.
367
368
369
370       openvpn_exec_t
371
372       - Set files with the openvpn_exec_t type, if you want to transition  an
373       executable to the openvpn_t domain.
374
375
376
377       openvpn_initrc_exec_t
378
379       - Set files with the openvpn_initrc_exec_t type, if you want to transi‐
380       tion an executable to the openvpn_initrc_t domain.
381
382
383
384       openvpn_tmp_t
385
386       - Set files with the openvpn_tmp_t type, if you want to  store  openvpn
387       temporary files in the /tmp directories.
388
389
390
391       openvpn_unconfined_script_exec_t
392
393       - Set files with the openvpn_unconfined_script_exec_t type, if you want
394       to transition an executable to the openvpn_unconfined_script_t domain.
395
396
397
398       openvpn_var_lib_t
399
400       - Set files with the openvpn_var_lib_t type, if you want to  store  the
401       openvpn files under the /var/lib directory.
402
403
404
405       openvpn_var_log_t
406
407       -  Set  files with the openvpn_var_log_t type, if you want to treat the
408       data as openvpn var log data, usually stored under the /var/log  direc‐
409       tory.
410
411
412
413       openvpn_var_run_t
414
415       -  Set  files with the openvpn_var_run_t type, if you want to store the
416       openvpn files under the /run or /var/run directory.
417
418
419
420       Note: File context can be temporarily modified with the chcon  command.
421       If  you want to permanently change the file context you need to use the
422       semanage fcontext command.  This will modify the SELinux labeling data‐
423       base.  You will need to use restorecon to apply the labels.
424
425

COMMANDS

427       semanage  fcontext  can also be used to manipulate default file context
428       mappings.
429
430       semanage permissive can also be used to manipulate  whether  or  not  a
431       process type is permissive.
432
433       semanage  module can also be used to enable/disable/install/remove pol‐
434       icy modules.
435
436       semanage port can also be used to manipulate the port definitions
437
438       semanage boolean can also be used to manipulate the booleans
439
440
441       system-config-selinux is a GUI tool available to customize SELinux pol‐
442       icy settings.
