NAME

6       kerneloops_selinux  - Security Enhanced Linux Policy for the kerneloops
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  kerneloops_t SELinux type can be entered via the kerneloops_exec_t
25       file type.
26
27       The default entrypoint paths for the kerneloops_t domain are  the  fol‐
28       lowing:
29
30       /usr/sbin/kerneloops
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       kerneloops  policy  is very flexible allowing users to setup their ker‐
40       neloops processes in as secure a method as possible.
41
42       The following process types are defined for kerneloops:
43
44       kerneloops_t
45
46       Note: semanage permissive -a kerneloops_t  can  be  used  to  make  the
47       process  type  kerneloops_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux  policy  is  customizable based on least access required.  ker‐
54       neloops policy is extremely flexible  and  has  several  booleans  that
55       allow you to manipulate the policy and run kerneloops with the tightest
56       access possible.

MANAGED FILES

154       The SELinux process type kerneloops_t can manage files labeled with the
155       following file types.  The paths listed are the default paths for these
156       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

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

COMMANDS

275       semanage  fcontext  can also be used to manipulate default file context
276       mappings.
277
278       semanage permissive can also be used to manipulate  whether  or  not  a
279       process type is permissive.
280
281       semanage  module can also be used to enable/disable/install/remove pol‐
282       icy modules.
283
284       semanage boolean can also be used to manipulate the booleans
285
286
287       system-config-selinux is a GUI tool available to customize SELinux pol‐
288       icy settings.
