NAME

6       nut_upsd_selinux - Security Enhanced Linux Policy for the nut_upsd pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

MANAGED FILES

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

FILE CONTEXTS

219       SELinux requires files to have an extended attribute to define the file
220       type.
221
222       You can see the context of a file using the -Z option to ls
223
224       Policy  governs  the  access  confined  processes  have to these files.
225       SELinux nut_upsd policy is very flexible allowing users to setup  their
226       nut_upsd processes in as secure a method as possible.
227
228       STANDARD FILE CONTEXT
229
230       SELinux  defines the file context types for the nut_upsd, if you wanted
231       to store files with these types in a diffent paths, you need to execute
232       the  semanage  command  to  sepecify  alternate  labeling  and then use
233       restorecon to put the labels on disk.
234
235       semanage  fcontext  -a  -t  nut_upsdrvctl_tmp_t   '/srv/mynut_upsd_con‐
236       tent(/.*)?'
237       restorecon -R -v /srv/mynut_upsd_content
238
239       Note:  SELinux  often  uses  regular expressions to specify labels that
240       match multiple files.
241
242       The following file types are defined for nut_upsd:
243
244
245
246       nut_upsd_exec_t
247
248       - Set files with the nut_upsd_exec_t type, if you want to transition an
249       executable to the nut_upsd_t domain.
250
251
252
253       nut_upsd_tmp_t
254
255       - Set files with the nut_upsd_tmp_t type, if you want to store nut upsd
256       temporary files in the /tmp directories.
257
258
259
260       nut_upsdrvctl_exec_t
261
262       - Set files with the nut_upsdrvctl_exec_t type, if you want to  transi‐
263       tion an executable to the nut_upsdrvctl_t domain.
264
265
266       Paths:
267            /sbin/upsdrvctl, /usr/sbin/upsdrvctl, /usr/sbin/blazer_usb
268
269
270       nut_upsdrvctl_tmp_t
271
272       - Set files with the nut_upsdrvctl_tmp_t type, if you want to store nut
273       upsdrvctl temporary files in the /tmp directories.
274
275
276
277       Note: File context can be temporarily modified with the chcon  command.
278       If  you want to permanently change the file context you need to use the
279       semanage fcontext command.  This will modify the SELinux labeling data‐
280       base.  You will need to use restorecon to apply the labels.
281
282

COMMANDS

284       semanage  fcontext  can also be used to manipulate default file context
285       mappings.
286
287       semanage permissive can also be used to manipulate  whether  or  not  a
288       process type is permissive.
289
290       semanage  module can also be used to enable/disable/install/remove pol‐
291       icy modules.
292
293       semanage boolean can also be used to manipulate the booleans
294
295
296       system-config-selinux is a GUI tool available to customize SELinux pol‐
297       icy settings.
