6 systemd_logind_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_logind processes
8
10 Security-Enhanced Linux secures the systemd_logind processes via flexi‐
11 ble mandatory access control.
12
13 The systemd_logind processes execute with the systemd_logind_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep systemd_logind_t
20
21
22
24 The systemd_logind_t SELinux type can be entered via the sys‐
25 temd_logind_exec_t file type.
26
27 The default entrypoint paths for the systemd_logind_t domain are the
28 following:
29
30 /usr/lib/systemd/systemd-logind, /usr/lib/systemd/systemd-user-runtime-
31 dir
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 systemd_logind policy is very flexible allowing users to setup their
41 systemd_logind processes in as secure a method as possible.
42
43 The following process types are defined for systemd_logind:
44
45 systemd_logind_t
46
47 Note: semanage permissive -a systemd_logind_t can be used to make the
48 process type systemd_logind_t permissive. SELinux does not deny access
49 to permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
52
54 SELinux policy is customizable based on least access required. sys‐
55 temd_logind policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run systemd_logind with the
57 tightest access possible.
58
59
60
61 If you want to allow all domains to execute in fips_mode, you must turn
62 on the fips_mode boolean. Enabled by default.
63
64 setsebool -P fips_mode 1
65
66
67
68 If you want to allow nagios/nrpe to call sudo from NRPE utils scripts,
69 you must turn on the nagios_run_sudo boolean. Disabled by default.
70
71 setsebool -P nagios_run_sudo 1
72
73
74
75 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77
78 setsebool -P nis_enabled 1
79
80
81
82 If you want to allow Zabbix to run su/sudo, you must turn on the zab‐
83 bix_run_sudo boolean. Disabled by default.
84
85 setsebool -P zabbix_run_sudo 1
86
87
88
89 If you want to allow ZoneMinder to run su/sudo, you must turn on the
90 zoneminder_run_sudo boolean. Disabled by default.
91
92 setsebool -P zoneminder_run_sudo 1
93

97 The SELinux process type systemd_logind_t can manage files labeled with
98 the following file types. The paths listed are the default paths for
99 these file types. Note the processes UID still need to have DAC per‐
100 missions.

207 SELinux requires files to have an extended attribute to define the file
208 type.
209
210 You can see the context of a file using the -Z option to ls
211
212 Policy governs the access confined processes have to these files.
213 SELinux systemd_logind policy is very flexible allowing users to setup
214 their systemd_logind processes in as secure a method as possible.
215
216 STANDARD FILE CONTEXT
217
218 SELinux defines the file context types for the systemd_logind, if you
219 wanted to store files with these types in a diffent paths, you need to
220 execute the semanage command to sepecify alternate labeling and then
221 use restorecon to put the labels on disk.
222
223 semanage fcontext -a -t systemd_logind_inhibit_var_run_t '/srv/mysys‐
224 temd_logind_content(/.*)?'
225 restorecon -R -v /srv/mysystemd_logind_content
226
227 Note: SELinux often uses regular expressions to specify labels that
228 match multiple files.
229
230 The following file types are defined for systemd_logind:
231
232
233
234 systemd_logind_exec_t
235
236 - Set files with the systemd_logind_exec_t type, if you want to transi‐
237 tion an executable to the systemd_logind_t domain.
238
239
240 Paths:
241 /usr/lib/systemd/systemd-logind, /usr/lib/systemd/systemd-user-
242 runtime-dir
243
244
245 systemd_logind_inhibit_var_run_t
246
247 - Set files with the systemd_logind_inhibit_var_run_t type, if you want
248 to store the systemd logind inhibit files under the /run or /var/run
249 directory.
250
251
252
253 systemd_logind_sessions_t
254
255 - Set files with the systemd_logind_sessions_t type, if you want to
256 treat the files as systemd logind sessions data.
257
258
259
260 systemd_logind_var_lib_t
261
262 - Set files with the systemd_logind_var_lib_t type, if you want to
263 store the systemd logind files under the /var/lib directory.
264
265
266
267 systemd_logind_var_run_t
268
269 - Set files with the systemd_logind_var_run_t type, if you want to
270 store the systemd logind files under the /run or /var/run directory.
271
272
273 Paths:
274 /var/run/.*nologin.*, /var/run/systemd/seats(/.*)?, /var/run/sys‐
275 temd/users(/.*)?, /var/run/systemd/shutdown(/.*)?
276
277
278 Note: File context can be temporarily modified with the chcon command.
279 If you want to permanently change the file context you need to use the
280 semanage fcontext command. This will modify the SELinux labeling data‐
281 base. You will need to use restorecon to apply the labels.
282
283
285 semanage fcontext can also be used to manipulate default file context
286 mappings.
287
288 semanage permissive can also be used to manipulate whether or not a
289 process type is permissive.
290
291 semanage module can also be used to enable/disable/install/remove pol‐
292 icy modules.
293
294 semanage boolean can also be used to manipulate the booleans
295
296
297 system-config-selinux is a GUI tool available to customize SELinux pol‐
298 icy settings.
