NAME

6       nut_upsdrvctl_selinux - Security Enhanced Linux Policy for the nut_ups‐
7       drvctl processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the nut_upsdrvctl processes via  flexi‐
11       ble mandatory access control.
12
13       The  nut_upsdrvctl  processes  execute with the nut_upsdrvctl_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 nut_upsdrvctl_t
20
21
22

ENTRYPOINTS

24       The  nut_upsdrvctl_t  SELinux  type  can  be  entered  via the nut_ups‐
25       drvctl_exec_t file type.
26
27       The default entrypoint paths for the  nut_upsdrvctl_t  domain  are  the
28       following:
29
30       /sbin/upsdrvctl, /usr/sbin/upsdrvctl, /usr/sbin/blazer_usb
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       nut_upsdrvctl  policy  is  very  flexible allowing users to setup their
40       nut_upsdrvctl processes in as secure a method as possible.
41
42       The following process types are defined for nut_upsdrvctl:
43
44       nut_upsdrvctl_t
45
46       Note: semanage permissive -a nut_upsdrvctl_t can be used  to  make  the
47       process  type  nut_upsdrvctl_t permissive. SELinux does not deny access
48       to permissive process types, but the AVC (SELinux denials) messages are
49       still generated.

51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       nut_upsdrvctl policy is extremely flexible  and  has  several  booleans
55       that  allow you to manipulate the policy and run nut_upsdrvctl with the
56       tightest access possible.

MANAGED FILES

171       The SELinux process type nut_upsdrvctl_t can manage files labeled  with
172       the  following  file types.  The paths listed are the default paths for
173       these file types.  Note the processes UID still need to have  DAC  per‐
174       missions.

FILE CONTEXTS

220       SELinux requires files to have an extended attribute to define the file
221       type.
222
223       You can see the context of a file using the -Z option to ls
224
225       Policy governs the access  confined  processes  have  to  these  files.
226       SELinux  nut_upsdrvctl  policy is very flexible allowing users to setup
227       their nut_upsdrvctl processes in as secure a method as possible.
228
229       STANDARD FILE CONTEXT
230
231       SELinux defines the file context types for the  nut_upsdrvctl,  if  you
232       wanted  to store files with these types in a diffent paths, you need to
233       execute the semanage command to sepecify alternate  labeling  and  then
234       use restorecon to put the labels on disk.
235
236       semanage  fcontext -a -t nut_upsdrvctl_tmp_t '/srv/mynut_upsdrvctl_con‐
237       tent(/.*)?'
238       restorecon -R -v /srv/mynut_upsdrvctl_content
239
240       Note: SELinux often uses regular expressions  to  specify  labels  that
241       match multiple files.
242
243       The following file types are defined for nut_upsdrvctl:
244
245
246
247       nut_upsdrvctl_exec_t
248
249       -  Set files with the nut_upsdrvctl_exec_t type, if you want to transi‐
250       tion an executable to the nut_upsdrvctl_t domain.
251
252
253       Paths:
254            /sbin/upsdrvctl, /usr/sbin/upsdrvctl, /usr/sbin/blazer_usb
255
256
257       nut_upsdrvctl_tmp_t
258
259       - Set files with the nut_upsdrvctl_tmp_t type, if you want to store nut
260       upsdrvctl temporary files in the /tmp directories.
261
262
263
264       Note:  File context can be temporarily modified with the chcon command.
265       If you want to permanently change the file context you need to use  the
266       semanage fcontext command.  This will modify the SELinux labeling data‐
267       base.  You will need to use restorecon to apply the labels.
268
269

COMMANDS

271       semanage fcontext can also be used to manipulate default  file  context
272       mappings.
273
274       semanage  permissive  can  also  be used to manipulate whether or not a
275       process type is permissive.
276
277       semanage module can also be used to enable/disable/install/remove  pol‐
278       icy modules.
279
280       semanage boolean can also be used to manipulate the booleans
281
282
283       system-config-selinux is a GUI tool available to customize SELinux pol‐
284       icy settings.
