NAME

6       vpnc_selinux - Security Enhanced Linux Policy for the vpnc processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The vpnc_t SELinux type can be entered via the vpnc_exec_t file type.
24
25       The default entrypoint paths for the vpnc_t domain are the following:
26
27       /sbin/vpnc, /usr/sbin/vpnc, /usr/bin/openconnect
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       vpnc policy is very flexible allowing users to setup  their  vpnc  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for vpnc:
40
41       vpnc_t
42
43       Note:  semanage  permissive  -a  vpnc_t can be used to make the process
44       type vpnc_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   vpnc
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run vpnc with the tightest access possible.
53
54
55
56       If you want to allow users to resolve user passwd entries directly from
57       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
58       gin_nsswitch_use_ldap boolean. Disabled by default.

88       executed with systemd.log_target=kmsg parameter, you must turn  on  the
89       domain_can_write_kmsg boolean. Disabled by default.

MANAGED FILES

153       The SELinux process type vpnc_t can manage files labeled with the  fol‐
154       lowing  file  types.   The paths listed are the default paths for these
155       file types.  Note the processes UID still need to have DAC permissions.
156
157       NetworkManager_var_run_t

FILE CONTEXTS

196       SELinux requires files to have an extended attribute to define the file
197       type.
198
199       You can see the context of a file using the -Z option to ls
200
201       Policy  governs  the  access  confined  processes  have to these files.
202       SELinux vpnc policy is very flexible allowing users to setup their vpnc
203       processes in as secure a method as possible.
204
205       STANDARD FILE CONTEXT
206
207       SELinux  defines  the file context types for the vpnc, if you wanted to
208       store files with these types in a diffent paths, you  need  to  execute
209       the  semanage  command  to  sepecify  alternate  labeling  and then use
210       restorecon to put the labels on disk.
211
212       semanage fcontext -a -t vpnc_var_run_t '/srv/myvpnc_content(/.*)?'
213       restorecon -R -v /srv/myvpnc_content
214
215       Note: SELinux often uses regular expressions  to  specify  labels  that
216       match multiple files.
217
218       The following file types are defined for vpnc:
219
220
221
222       vpnc_exec_t
223
224       -  Set  files  with  the vpnc_exec_t type, if you want to transition an
225       executable to the vpnc_t domain.
226
227
228       Paths:
229            /sbin/vpnc, /usr/sbin/vpnc, /usr/bin/openconnect
230
231
232       vpnc_tmp_t
233
234       - Set files with the vpnc_tmp_t type, if you want to store vpnc  tempo‐
235       rary files in the /tmp directories.
236
237
238
239       vpnc_var_run_t
240
241       - Set files with the vpnc_var_run_t type, if you want to store the vpnc
242       files under the /run or /var/run directory.
243
244
245
246       Note: File context can be temporarily modified with the chcon  command.
247       If  you want to permanently change the file context you need to use the
248       semanage fcontext command.  This will modify the SELinux labeling data‐
249       base.  You will need to use restorecon to apply the labels.
250
251

COMMANDS

253       semanage  fcontext  can also be used to manipulate default file context
254       mappings.
255
256       semanage permissive can also be used to manipulate  whether  or  not  a
257       process type is permissive.
258
259       semanage  module can also be used to enable/disable/install/remove pol‐
260       icy modules.
261
262       semanage boolean can also be used to manipulate the booleans
263
264
265       system-config-selinux is a GUI tool available to customize SELinux pol‐
266       icy settings.
