NAME

6       kdumpgui_selinux - Security Enhanced Linux Policy for the kdumpgui pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

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       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

BOOLEANS

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.

MANAGED FILES

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.

FILE CONTEXTS

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

COMMANDS

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.
