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
55 allow you to manipulate the policy and run kdumpgui with the tightest
56 access 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 allow all domains to execute in fips_mode, you must turn
68 on the fips_mode boolean. Enabled by default.
69 setsebool -P fips_mode 1
71 If you want to allow system to run with NIS, you must turn on the
75 nis_enabled boolean. Disabled by default.
76 setsebool -P nis_enabled 1
78
82 The SELinux process type kdumpgui_t can manage files labeled with the
83 following file types. The paths listed are the default paths for these
84 file types. Note the processes UID still need to have DAC permissions.

142 SELinux requires files to have an extended attribute to define the file
143 type.
144 You can see the context of a file using the -Z option to ls
146 Policy governs the access confined processes have to these files.
148 SELinux kdumpgui policy is very flexible allowing users to setup their
149 kdumpgui processes in as secure a method as possible.
150 STANDARD FILE CONTEXT
152 SELinux defines the file context types for the kdumpgui, if you wanted
154 to store files with these types in a diffent paths, you need to execute
155 the semanage command to sepecify alternate labeling and then use
156 restorecon to put the labels on disk.
157 semanage fcontext -a -t kdumpgui_tmp_t '/srv/mykdumpgui_content(/.*)?'
159 restorecon -R -v /srv/mykdumpgui_content
160 Note: SELinux often uses regular expressions to specify labels that
162 match multiple files.
163 The following file types are defined for kdumpgui:
165 kdumpgui_exec_t
169 - Set files with the kdumpgui_exec_t type, if you want to transition an
171 executable to the kdumpgui_t domain.
172 kdumpgui_tmp_t
176 - Set files with the kdumpgui_tmp_t type, if you want to store kdumpgui
178 temporary files in the /tmp directories.
179 Note: File context can be temporarily modified with the chcon command.
183 If you want to permanently change the file context you need to use the
184 semanage fcontext command. This will modify the SELinux labeling data‐
185 base. You will need to use restorecon to apply the labels.
186
189 semanage fcontext can also be used to manipulate default file context
190 mappings.
191 semanage permissive can also be used to manipulate whether or not a
193 process type is permissive.
194 semanage module can also be used to enable/disable/install/remove pol‐
196 icy modules.
197 semanage boolean can also be used to manipulate the booleans
199 system-config-selinux is a GUI tool available to customize SELinux pol‐
202 icy settings.
