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.
57
58
59
60 If you want to allow s-c-kdump to run bootloader in bootloader_t, you
61 must turn on the kdumpgui_run_bootloader boolean. Disabled by default.
62
63 setsebool -P kdumpgui_run_bootloader 1
64
65
66
67 If you want to allow users to resolve user passwd entries directly from
68 ldap rather then using a sssd server, you must turn on the authlo‐
69 gin_nsswitch_use_ldap boolean. Disabled by default.
70
71 setsebool -P authlogin_nsswitch_use_ldap 1
72
73
74
75 If you want to allow all domains to execute in fips_mode, you must turn
76 on the fips_mode boolean. Enabled by default.
77
78 setsebool -P fips_mode 1
79
80
81
82 If you want to allow confined applications to run with kerberos, you
83 must turn on the kerberos_enabled boolean. Enabled by default.
84
85 setsebool -P kerberos_enabled 1
86
87
88
89 If you want to allow system to run with NIS, you must turn on the
90 nis_enabled boolean. Disabled by default.
91
92 setsebool -P nis_enabled 1
93
94
95
96 If you want to allow confined applications to use nscd shared memory,
97 you must turn on the nscd_use_shm boolean. Enabled by default.
98
99 setsebool -P nscd_use_shm 1

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

204 SELinux requires files to have an extended attribute to define the file
205 type.
206
207 You can see the context of a file using the -Z option to ls
208
209 Policy governs the access confined processes have to these files.
210 SELinux kdumpgui policy is very flexible allowing users to setup their
211 kdumpgui processes in as secure a method as possible.
212
213 STANDARD FILE CONTEXT
214
215 SELinux defines the file context types for the kdumpgui, if you wanted
216 to store files with these types in a diffent paths, you need to execute
217 the semanage command to sepecify alternate labeling and then use
218 restorecon to put the labels on disk.
219
220 semanage fcontext -a -t kdumpgui_tmp_t '/srv/mykdumpgui_content(/.*)?'
221 restorecon -R -v /srv/mykdumpgui_content
222
223 Note: SELinux often uses regular expressions to specify labels that
224 match multiple files.
225
226 The following file types are defined for kdumpgui:
227
228
229
230 kdumpgui_exec_t
231
232 - Set files with the kdumpgui_exec_t type, if you want to transition an
233 executable to the kdumpgui_t domain.
234
235
236
237 kdumpgui_tmp_t
238
239 - Set files with the kdumpgui_tmp_t type, if you want to store kdumpgui
240 temporary files in the /tmp directories.
241
242
243
244 Note: File context can be temporarily modified with the chcon command.
245 If you want to permanently change the file context you need to use the
246 semanage fcontext command. This will modify the SELinux labeling data‐
247 base. You will need to use restorecon to apply the labels.
248
249
251 semanage fcontext can also be used to manipulate default file context
252 mappings.
253
254 semanage permissive can also be used to manipulate whether or not a
255 process type is permissive.
256
257 semanage module can also be used to enable/disable/install/remove pol‐
258 icy modules.
259
260 semanage boolean can also be used to manipulate the booleans
261
262
263 system-config-selinux is a GUI tool available to customize SELinux pol‐
264 icy settings.
