6 kdumpgui_selinux - Security Enhanced Linux Policy for the kdumpgui pro‐
7 cesses
8
10 Security-Enhanced Linux secures the kdumpgui processes via flexible
11 mandatory access control.
12
13 The kdumpgui processes execute with the kdumpgui_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep kdumpgui_t
20
21
22
24 The kdumpgui_t SELinux type can be entered via the kdumpgui_exec_t file
25 type.
26
27 The default entrypoint paths for the kdumpgui_t domain are the follow‐
28 ing:
29
30 /usr/share/system-config-kdump/system-config-kdump-backend.py
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 kdumpgui policy is very flexible allowing users to setup their kdumpgui
40 processes in as secure a method as possible.
41
42 The following process types are defined for kdumpgui:
43
44 kdumpgui_t
45
46 Note: semanage permissive -a kdumpgui_t can be used to make the process
47 type kdumpgui_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required.
54 kdumpgui policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run kdumpgui with the tightest
56 access possible.

178 The SELinux process type kdumpgui_t can manage files labeled with the
179 following file types. The paths listed are the default paths for these
180 file types. Note the processes UID still need to have DAC permissions.

278 SELinux requires files to have an extended attribute to define the file
279 type.
280
281 You can see the context of a file using the -Z option to ls
282
283 Policy governs the access confined processes have to these files.
284 SELinux kdumpgui policy is very flexible allowing users to setup their
285 kdumpgui processes in as secure a method as possible.
286
287 STANDARD FILE CONTEXT
288
289 SELinux defines the file context types for the kdumpgui, if you wanted
290 to store files with these types in a diffent paths, you need to execute
291 the semanage command to sepecify alternate labeling and then use
292 restorecon to put the labels on disk.
293
294 semanage fcontext -a -t kdumpgui_tmp_t '/srv/mykdumpgui_content(/.*)?'
295 restorecon -R -v /srv/mykdumpgui_content
296
297 Note: SELinux often uses regular expressions to specify labels that
298 match multiple files.
299
300 The following file types are defined for kdumpgui:
301
302
303
304 kdumpgui_exec_t
305
306 - Set files with the kdumpgui_exec_t type, if you want to transition an
307 executable to the kdumpgui_t domain.
308
309
310
311 kdumpgui_tmp_t
312
313 - Set files with the kdumpgui_tmp_t type, if you want to store kdumpgui
314 temporary files in the /tmp directories.
315
316
317
318 Note: File context can be temporarily modified with the chcon command.
319 If you want to permanently change the file context you need to use the
320 semanage fcontext command. This will modify the SELinux labeling data‐
321 base. You will need to use restorecon to apply the labels.
322
323
325 semanage fcontext can also be used to manipulate default file context
326 mappings.
327
328 semanage permissive can also be used to manipulate whether or not a
329 process type is permissive.
330
331 semanage module can also be used to enable/disable/install/remove pol‐
332 icy modules.
333
334 semanage boolean can also be used to manipulate the booleans
335
336
337 system-config-selinux is a GUI tool available to customize SELinux pol‐
338 icy settings.
