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 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 For example:
18 ps -eZ | grep kdumpgui_t
20
24 The kdumpgui_t SELinux type can be entered via the kdumpgui_exec_t file
25 type.
26 The default entrypoint paths for the kdumpgui_t domain are the follow‐
28 ing:
29 /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 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for kdumpgui:
43 kdumpgui_t
45 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
53 SELinux policy is customizable based on least access required.
54 kdumpgui policy is extremely flexible and has several booleans that al‐
55 low you to manipulate the policy and run kdumpgui with the tightest ac‐
56 cess possible.
57 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 setsebool -P kdumpgui_run_bootloader 1
64 If you want to dontaudit all daemons scheduling requests (setsched,
68 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
69 Enabled by default.
70 setsebool -P daemons_dontaudit_scheduling 1
72 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 setsebool -P fips_mode 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86
90 The SELinux process type kdumpgui_t can manage files labeled with the
91 following file types. The paths listed are the default paths for these
92 file types. Note the processes UID still need to have DAC permissions.

168 SELinux requires files to have an extended attribute to define the file
169 type.
170 You can see the context of a file using the -Z option to ls
172 Policy governs the access confined processes have to these files.
174 SELinux kdumpgui policy is very flexible allowing users to setup their
175 kdumpgui processes in as secure a method as possible.
176 STANDARD FILE CONTEXT
178 SELinux defines the file context types for the kdumpgui, if you wanted
180 to store files with these types in a different paths, you need to exe‐
181 cute the semanage command to specify alternate labeling and then use
182 restorecon to put the labels on disk.
183 semanage fcontext -a -t kdumpgui_exec_t '/srv/kdumpgui/content(/.*)?'
185 restorecon -R -v /srv/mykdumpgui_content
186 Note: SELinux often uses regular expressions to specify labels that
188 match multiple files.
189 The following file types are defined for kdumpgui:
191 kdumpgui_exec_t
195 - Set files with the kdumpgui_exec_t type, if you want to transition an
197 executable to the kdumpgui_t domain.
198 kdumpgui_tmp_t
202 - Set files with the kdumpgui_tmp_t type, if you want to store kdumpgui
204 temporary files in the /tmp directories.
205 Note: File context can be temporarily modified with the chcon command.
209 If you want to permanently change the file context you need to use the
210 semanage fcontext command. This will modify the SELinux labeling data‐
211 base. You will need to use restorecon to apply the labels.
212
215 semanage fcontext can also be used to manipulate default file context
216 mappings.
217 semanage permissive can also be used to manipulate whether or not a
219 process type is permissive.
220 semanage module can also be used to enable/disable/install/remove pol‐
222 icy modules.
223 semanage boolean can also be used to manipulate the booleans
225 system-config-selinux is a GUI tool available to customize SELinux pol‐
228 icy settings.
