NAME

6       iwhd_selinux - Security Enhanced Linux Policy for the iwhd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The iwhd_t SELinux type can be entered via the iwhd_exec_t file type.
24
25       The default entrypoint paths for the iwhd_t domain are the following:
26
27       /usr/bin/iwhd
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       iwhd policy is very flexible allowing users to setup  their  iwhd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for iwhd:
40
41       iwhd_t
42
43       Note:  semanage  permissive  -a  iwhd_t can be used to make the process
44       type iwhd_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   iwhd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run iwhd with the tightest access possible.

MANAGED FILES

166       The  SELinux process type iwhd_t can manage files labeled with the fol‐
167       lowing file types.  The paths listed are the default  paths  for  these
168       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

234       SELinux requires files to have an extended attribute to define the file
235       type.
236
237       You can see the context of a file using the -Z option to ls
238
239       Policy governs the access  confined  processes  have  to  these  files.
240       SELinux iwhd policy is very flexible allowing users to setup their iwhd
241       processes in as secure a method as possible.
242
243       STANDARD FILE CONTEXT
244
245       SELinux defines the file context types for the iwhd, if you  wanted  to
246       store  files  with  these types in a diffent paths, you need to execute
247       the semanage command  to  sepecify  alternate  labeling  and  then  use
248       restorecon to put the labels on disk.
249
250       semanage fcontext -a -t iwhd_var_run_t '/srv/myiwhd_content(/.*)?'
251       restorecon -R -v /srv/myiwhd_content
252
253       Note:  SELinux  often  uses  regular expressions to specify labels that
254       match multiple files.
255
256       The following file types are defined for iwhd:
257
258
259
260       iwhd_exec_t
261
262       - Set files with the iwhd_exec_t type, if you  want  to  transition  an
263       executable to the iwhd_t domain.
264
265
266
267       iwhd_initrc_exec_t
268
269       - Set files with the iwhd_initrc_exec_t type, if you want to transition
270       an executable to the iwhd_initrc_t domain.
271
272
273
274       iwhd_log_t
275
276       - Set files with the iwhd_log_t type, if you want to treat the data  as
277       iwhd log data, usually stored under the /var/log directory.
278
279
280
281       iwhd_var_lib_t
282
283       - Set files with the iwhd_var_lib_t type, if you want to store the iwhd
284       files under the /var/lib directory.
285
286
287
288       iwhd_var_run_t
289
290       - Set files with the iwhd_var_run_t type, if you want to store the iwhd
291       files under the /run or /var/run directory.
292
293
294
295       Note:  File context can be temporarily modified with the chcon command.
296       If you want to permanently change the file context you need to use  the
297       semanage fcontext command.  This will modify the SELinux labeling data‐
298       base.  You will need to use restorecon to apply the labels.
299
300

COMMANDS

302       semanage fcontext can also be used to manipulate default  file  context
303       mappings.
304
305       semanage  permissive  can  also  be used to manipulate whether or not a
306       process type is permissive.
307
308       semanage module can also be used to enable/disable/install/remove  pol‐
309       icy modules.
310
311       semanage boolean can also be used to manipulate the booleans
312
313
314       system-config-selinux is a GUI tool available to customize SELinux pol‐
315       icy settings.
