NAME

6       kmscon_selinux  -  Security  Enhanced  Linux Policy for the kmscon pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  kmscon  processes  via  flexible
11       mandatory access control.
12
13       The  kmscon  processes  execute with the kmscon_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 kmscon_t
20
21
22

ENTRYPOINTS

24       The  kmscon_t  SELinux  type  can be entered via the kmscon_exec_t file
25       type.
26
27       The default entrypoint paths for the kmscon_t domain are the following:
28
29       /usr/bin/kmscon
30

PROCESS TYPES

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

BOOLEANS

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

MANAGED FILES

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

FILE CONTEXTS

185       SELinux requires files to have an extended attribute to define the file
186       type.
187
188       You can see the context of a file using the -Z option to ls
189
190       Policy governs the access  confined  processes  have  to  these  files.
191       SELinux  kmscon  policy  is very flexible allowing users to setup their
192       kmscon processes in as secure a method as possible.
193
194       STANDARD FILE CONTEXT
195
196       SELinux defines the file context types for the kmscon, if you wanted to
197       store  files  with  these types in a diffent paths, you need to execute
198       the semanage command  to  sepecify  alternate  labeling  and  then  use
199       restorecon to put the labels on disk.
200
201       semanage   fcontext   -a   -t   kmscon_unit_file_t  '/srv/mykmscon_con‐
202       tent(/.*)?'
203       restorecon -R -v /srv/mykmscon_content
204
205       Note: SELinux often uses regular expressions  to  specify  labels  that
206       match multiple files.
207
208       The following file types are defined for kmscon:
209
210
211
212       kmscon_conf_t
213
214       - Set files with the kmscon_conf_t type, if you want to treat the files
215       as kmscon configuration data, usually stored under the /etc directory.
216
217
218
219       kmscon_exec_t
220
221       - Set files with the kmscon_exec_t type, if you want to  transition  an
222       executable to the kmscon_t domain.
223
224
225
226       kmscon_unit_file_t
227
228       -  Set files with the kmscon_unit_file_t type, if you want to treat the
229       files as kmscon unit content.
230
231
232
233       Note: File context can be temporarily modified with the chcon  command.
234       If  you want to permanently change the file context you need to use the
235       semanage fcontext command.  This will modify the SELinux labeling data‐
236       base.  You will need to use restorecon to apply the labels.
237
238

COMMANDS

240       semanage  fcontext  can also be used to manipulate default file context
241       mappings.
242
243       semanage permissive can also be used to manipulate  whether  or  not  a
244       process type is permissive.
245
246       semanage  module can also be used to enable/disable/install/remove pol‐
247       icy modules.
248
249       semanage boolean can also be used to manipulate the booleans
250
251
252       system-config-selinux is a GUI tool available to customize SELinux pol‐
253       icy settings.
