NAME

6       sensord_selinux  -  Security Enhanced Linux Policy for the sensord pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

MANAGED FILES

142       The  SELinux  process  type sensord_t can manage files labeled with the
143       following file types.  The paths listed are the default paths for these
144       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

191       SELinux requires files to have an extended attribute to define the file
192       type.
193
194       You can see the context of a file using the -Z option to ls
195
196       Policy governs the access  confined  processes  have  to  these  files.
197       SELinux  sensord  policy is very flexible allowing users to setup their
198       sensord processes in as secure a method as possible.
199
200       STANDARD FILE CONTEXT
201
202       SELinux defines the file context types for the sensord, if  you  wanted
203       to store files with these types in a diffent paths, you need to execute
204       the semanage command  to  sepecify  alternate  labeling  and  then  use
205       restorecon to put the labels on disk.
206
207       semanage   fcontext   -a   -t   sensord_var_run_t  '/srv/mysensord_con‐
208       tent(/.*)?'
209       restorecon -R -v /srv/mysensord_content
210
211       Note: SELinux often uses regular expressions  to  specify  labels  that
212       match multiple files.
213
214       The following file types are defined for sensord:
215
216
217
218       sensord_exec_t
219
220       -  Set files with the sensord_exec_t type, if you want to transition an
221       executable to the sensord_t domain.
222
223
224
225       sensord_initrc_exec_t
226
227       - Set files with the sensord_initrc_exec_t type, if you want to transi‐
228       tion an executable to the sensord_initrc_t domain.
229
230
231
232       sensord_log_t
233
234       -  Set files with the sensord_log_t type, if you want to treat the data
235       as sensord log data, usually stored under the /var/log directory.
236
237
238
239       sensord_unit_file_t
240
241       - Set files with the sensord_unit_file_t type, if you want to treat the
242       files as sensord unit content.
243
244
245
246       sensord_var_run_t
247
248       -  Set  files with the sensord_var_run_t type, if you want to store the
249       sensord files under the /run or /var/run directory.
250
251
252
253       Note: File context can be temporarily modified with the chcon  command.
254       If  you want to permanently change the file context you need to use the
255       semanage fcontext command.  This will modify the SELinux labeling data‐
256       base.  You will need to use restorecon to apply the labels.
257
258

COMMANDS

260       semanage  fcontext  can also be used to manipulate default file context
261       mappings.
262
263       semanage permissive can also be used to manipulate  whether  or  not  a
264       process type is permissive.
265
266       semanage  module can also be used to enable/disable/install/remove pol‐
267       icy modules.
268
269       semanage boolean can also be used to manipulate the booleans
270
271
272       system-config-selinux is a GUI tool available to customize SELinux pol‐
273       icy settings.
