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/s?bin/NetworkManager,  /usr/s?bin/wpa_supplicant,  /usr/sbin/wicd,
31       /sbin/wpa_supplicant, /usr/sbin/nm-system-settings,  /usr/sbin/Network‐
32       ManagerDispatcher
33

PROCESS TYPES

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

BOOLEANS

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

FILE CONTEXTS

316       SELinux requires files to have an extended attribute to define the file
317       type.
318
319       You can see the context of a file using the -Z option to ls
320
321       Policy governs the access  confined  processes  have  to  these  files.
322       SELinux  NetworkManager policy is very flexible allowing users to setup
323       their NetworkManager processes in as secure a method as possible.
324
325       EQUIVALENCE DIRECTORIES
326
327
328       NetworkManager policy stores data with multiple different file  context
329       types  under  the  /var/log/wicd directory.  If you would like to store
330       the data in a different directory you can use the semanage  command  to
331       create  an equivalence mapping.  If you wanted to store this data under
332       the /srv dirctory you would execute the following command:
333
334       semanage fcontext -a -e /var/log/wicd /srv/wicd
335       restorecon -R -v /srv/wicd
336
337       NetworkManager policy stores data with multiple different file  context
338       types  under  the /var/run/wpa_supplicant directory.  If you would like
339       to store the data in a different directory you  can  use  the  semanage
340       command  to create an equivalence mapping.  If you wanted to store this
341       data under the /srv dirctory you would execute the following command:
342
343       semanage fcontext -a -e /var/run/wpa_supplicant /srv/wpa_supplicant
344       restorecon -R -v /srv/wpa_supplicant
345
346       NetworkManager policy stores data with multiple different file  context
347       types  under  the /var/run/NetworkManager directory.  If you would like
348       to store the data in a different directory you  can  use  the  semanage
349       command  to create an equivalence mapping.  If you wanted to store this
350       data under the /srv dirctory you would execute the following command:
351
352       semanage fcontext -a -e /var/run/NetworkManager /srv/NetworkManager
353       restorecon -R -v /srv/NetworkManager
354
355       STANDARD FILE CONTEXT
356
357       SELinux defines the file context types for the NetworkManager,  if  you
358       wanted  to store files with these types in a diffent paths, you need to
359       execute the semanage command to sepecify alternate  labeling  and  then
360       use restorecon to put the labels on disk.
361
362       semanage  fcontext  -a  -t NetworkManager_var_run_t '/srv/myNetworkMan‐
363       ager_content(/.*)?'
364       restorecon -R -v /srv/myNetworkManager_content
365
366       Note: SELinux often uses regular expressions  to  specify  labels  that
367       match multiple files.
368
369       The following file types are defined for NetworkManager:
370
371
372
373       NetworkManager_exec_t
374
375       - Set files with the NetworkManager_exec_t type, if you want to transi‐
376       tion an executable to the NetworkManager_t domain.
377
378
379       Paths:
380            /usr/s?bin/NetworkManager,              /usr/s?bin/wpa_supplicant,
381            /usr/sbin/wicd,   /sbin/wpa_supplicant,   /usr/sbin/nm-system-set‐
382            tings, /usr/sbin/NetworkManagerDispatcher
383
384
385       NetworkManager_initrc_exec_t
386
387       - Set files with the NetworkManager_initrc_exec_t type, if you want  to
388       transition an executable to the NetworkManager_initrc_t domain.
389
390
391       Paths:
392            /etc/NetworkManager/dispatcher.d(/.*)?,     /etc/rc.d/init.d/wicd,
393            /usr/libexec/nm-dispatcher.action
394
395
396       NetworkManager_log_t
397
398       - Set files with the NetworkManager_log_t type, if you  want  to  treat
399       the  data as NetworkManager log data, usually stored under the /var/log
400       directory.
401
402
403       Paths:
404            /var/log/wicd(/.*)?,   /var/log/wicd.log.*,   /var/log/wpa_suppli‐
405            cant.*
406
407
408       NetworkManager_tmp_t
409
410       -  Set  files  with the NetworkManager_tmp_t type, if you want to store
411       NetworkManager temporary files in the /tmp directories.
412
413
414
415       NetworkManager_var_lib_t
416
417       - Set files with the NetworkManager_var_lib_t  type,  if  you  want  to
418       store the NetworkManager files under the /var/lib directory.
419
420
421       Paths:
422            /var/lib/wicd(/.*)?,  /etc/NetworkManager(/.*)?, /var/lib/Network‐
423            Manager(/.*)?,  /etc/wicd/wired-settings.conf,  /etc/wicd/manager-
424            settings.conf,  /etc/wicd/wireless-settings.conf, /etc/NetworkMan‐
425            ager/system-connections(/.*)?
426
427
428       NetworkManager_var_run_t
429
430       - Set files with the NetworkManager_var_run_t  type,  if  you  want  to
431       store the NetworkManager files under the /run or /var/run directory.
432
433
434       Paths:
435            /var/run/nm-dhclient.*,             /var/run/wpa_supplicant(/.*)?,
436            /var/run/NetworkManager(/.*)?,        /var/run/NetworkManager.pid,
437            /var/run/wpa_supplicant-global
438
439
440       Note:  File context can be temporarily modified with the chcon command.
441       If you want to permanently change the file context you need to use  the
442       semanage fcontext command.  This will modify the SELinux labeling data‐
443       base.  You will need to use restorecon to apply the labels.
444
445

COMMANDS

447       semanage fcontext can also be used to manipulate default  file  context
448       mappings.
449
450       semanage  permissive  can  also  be used to manipulate whether or not a
451       process type is permissive.
452
453       semanage module can also be used to enable/disable/install/remove  pol‐
454       icy modules.
455
456       semanage boolean can also be used to manipulate the booleans
457
458
459       system-config-selinux is a GUI tool available to customize SELinux pol‐
460       icy settings.
