NAME

6       lwiod_selinux - Security Enhanced Linux Policy for the lwiod processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The lwiod_t SELinux type can be entered via the lwiod_exec_t file type.
24
25       The default entrypoint paths for the lwiod_t domain are the following:
26
27       /usr/sbin/lwiod
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       lwiod policy is very flexible allowing users to setup their lwiod  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for lwiod:
40
41       lwiod_t
42
43       Note:  semanage  permissive  -a lwiod_t can be used to make the process
44       type lwiod_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.   lwiod
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run lwiod with the tightest access possible.

MANAGED FILES

136       The SELinux process type lwiod_t can manage files labeled with the fol‐
137       lowing file types.  The paths listed are the default  paths  for  these
138       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

210       SELinux requires files to have an extended attribute to define the file
211       type.
212
213       You can see the context of a file using the -Z option to ls
214
215       Policy governs the access  confined  processes  have  to  these  files.
216       SELinux  lwiod  policy  is  very flexible allowing users to setup their
217       lwiod processes in as secure a method as possible.
218
219       STANDARD FILE CONTEXT
220
221       SELinux defines the file context types for the lwiod, if you wanted  to
222       store  files  with  these types in a diffent paths, you need to execute
223       the semanage command  to  sepecify  alternate  labeling  and  then  use
224       restorecon to put the labels on disk.
225
226       semanage fcontext -a -t lwiod_var_socket_t '/srv/mylwiod_content(/.*)?'
227       restorecon -R -v /srv/mylwiod_content
228
229       Note:  SELinux  often  uses  regular expressions to specify labels that
230       match multiple files.
231
232       The following file types are defined for lwiod:
233
234
235
236       lwiod_exec_t
237
238       - Set files with the lwiod_exec_t type, if you want  to  transition  an
239       executable to the lwiod_t domain.
240
241
242
243       lwiod_var_lib_t
244
245       -  Set  files  with  the lwiod_var_lib_t type, if you want to store the
246       lwiod files under the /var/lib directory.
247
248
249
250       lwiod_var_run_t
251
252       - Set files with the lwiod_var_run_t type, if you  want  to  store  the
253       lwiod files under the /run or /var/run directory.
254
255
256
257       lwiod_var_socket_t
258
259       -  Set files with the lwiod_var_socket_t type, if you want to treat the
260       files as lwiod var socket data.
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.
