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

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.

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
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.
