NAME

6       NetworkManager_selinux  -  Security  Enhanced Linux Policy for the Net‐
7       workManager processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  NetworkManager_t  SELinux  type can be entered via the NetworkMan‐
25       ager_exec_t file type.
26
27       The default entrypoint paths for the NetworkManager_t  domain  are  the
28       following:
29
30       /usr/libexec/nm-dispatcher.*,      /usr/bin/teamd,      /usr/sbin/wicd,
31       /usr/bin/NetworkManager, /usr/bin/wpa_supplicant, /usr/sbin/NetworkMan‐
32       ager,      /usr/sbin/wpa_supplicant,      /usr/sbin/nm-system-settings,
33       /usr/sbin/NetworkManagerDispatcher
34

PROCESS TYPES

36       SELinux defines process types (domains) for each process running on the
37       system
38
39       You can see the context of a process using the -Z option to ps
40
41       Policy  governs  the  access confined processes have to files.  SELinux
42       NetworkManager policy is very flexible allowing users  to  setup  their
43       NetworkManager processes in as secure a method as possible.
44
45       The following process types are defined for NetworkManager:
46
47       NetworkManager_t
48
49       Note:  semanage  permissive -a NetworkManager_t can be used to make the
50       process type NetworkManager_t permissive. SELinux does not deny  access
51       to permissive process types, but the AVC (SELinux denials) messages are
52       still generated.
53
54

BOOLEANS

56       SELinux policy is customizable based on least  access  required.   Net‐
57       workManager  policy is extremely flexible and has several booleans that
58       allow you to manipulate the policy  and  run  NetworkManager  with  the
59       tightest access possible.

FILE CONTEXTS

330       SELinux requires files to have an extended attribute to define the file
331       type.
332
333       You can see the context of a file using the -Z option to ls
334
335       Policy governs the access  confined  processes  have  to  these  files.
336       SELinux  NetworkManager policy is very flexible allowing users to setup
337       their NetworkManager processes in as secure a method as possible.
338
339       EQUIVALENCE DIRECTORIES
340
341
342       NetworkManager policy stores data with multiple different file  context
343       types  under  the /var/run/wpa_supplicant directory.  If you would like
344       to store the data in a different directory you  can  use  the  semanage
345       command  to create an equivalence mapping.  If you wanted to store this
346       data under the /srv dirctory you would execute the following command:
347
348       semanage fcontext -a -e /var/run/wpa_supplicant /srv/wpa_supplicant
349       restorecon -R -v /srv/wpa_supplicant
350
351       NetworkManager policy stores data with multiple different file  context
352       types  under  the /var/run/NetworkManager directory.  If you would like
353       to store the data in a different directory you  can  use  the  semanage
354       command  to create an equivalence mapping.  If you wanted to store this
355       data under the /srv dirctory you would execute the following command:
356
357       semanage fcontext -a -e /var/run/NetworkManager /srv/NetworkManager
358       restorecon -R -v /srv/NetworkManager
359
360       STANDARD FILE CONTEXT
361
362       SELinux defines the file context types for the NetworkManager,  if  you
363       wanted  to store files with these types in a diffent paths, you need to
364       execute the semanage command to sepecify alternate  labeling  and  then
365       use restorecon to put the labels on disk.
366
367       semanage  fcontext  -a  -t NetworkManager_var_run_t '/srv/myNetworkMan‐
368       ager_content(/.*)?'
369       restorecon -R -v /srv/myNetworkManager_content
370
371       Note: SELinux often uses regular expressions  to  specify  labels  that
372       match multiple files.
373
374       The following file types are defined for NetworkManager:
375
