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 daemons the ability to read/write terminals,
68 you must turn on the allow_daemons_use_tty boolean. Disabled by
69 default.
70 setsebool -P allow_daemons_use_tty 1
72 If you want to allow all domains to use other domains file descriptors,
76 you must turn on the allow_domain_fd_use boolean. Enabled by default.
77 setsebool -P allow_domain_fd_use 1
79 If you want to allow confined applications to run with kerberos, you
83 must turn on the allow_kerberos boolean. Enabled by default.
84 setsebool -P allow_kerberos 1
86 If you want to allow sysadm to debug or ptrace all processes, you must
90 turn on the allow_ptrace boolean. Disabled by default.
91 setsebool -P allow_ptrace 1
93 If you want to allow system to run with NIS, you must turn on the
97 allow_ypbind boolean. Disabled by default.
98 setsebool -P allow_ypbind 1
100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to allow confined applications to use nscd shared memory,
126 you must turn on the nscd_use_shm boolean. Enabled by default.
127 setsebool -P nscd_use_shm 1
129
133 The SELinux process type kdumpgui_t can manage files labeled with the
134 following file types. The paths listed are the default paths for these
135 file types. Note the processes UID still need to have DAC permissions.

223 SELinux requires files to have an extended attribute to define the file
224 type.
225 You can see the context of a file using the -Z option to ls
227 Policy governs the access confined processes have to these files.
229 SELinux kdumpgui policy is very flexible allowing users to setup their
230 kdumpgui processes in as secure a method as possible.
231 STANDARD FILE CONTEXT
233 SELinux defines the file context types for the kdumpgui, if you wanted
235 to store files with these types in a diffent paths, you need to execute
236 the semanage command to sepecify alternate labeling and then use
237 restorecon to put the labels on disk.
238 semanage fcontext -a -t kdumpgui_tmp_t '/srv/mykdumpgui_content(/.*)?'
240 restorecon -R -v /srv/mykdumpgui_content
241 Note: SELinux often uses regular expressions to specify labels that
243 match multiple files.
244 The following file types are defined for kdumpgui:
246 kdumpgui_exec_t
250 - Set files with the kdumpgui_exec_t type, if you want to transition an
252 executable to the kdumpgui_t domain.
253 kdumpgui_tmp_t
257 - Set files with the kdumpgui_tmp_t type, if you want to store kdumpgui
259 temporary files in the /tmp directories.
260 Note: File context can be temporarily modified with the chcon command.
264 If you want to permanently change the file context you need to use the
265 semanage fcontext command. This will modify the SELinux labeling data‐
266 base. You will need to use restorecon to apply the labels.
267
270 semanage fcontext can also be used to manipulate default file context
271 mappings.
272 semanage permissive can also be used to manipulate whether or not a
274 process type is permissive.
275 semanage module can also be used to enable/disable/install/remove pol‐
277 icy modules.
278 semanage boolean can also be used to manipulate the booleans
280 system-config-selinux is a GUI tool available to customize SELinux pol‐
283 icy settings.
