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.

60
61 If you want to allow users to resolve user passwd entries directly from
62 ldap rather then using a sssd server, you must turn on the authlo‐
63 gin_nsswitch_use_ldap boolean. Disabled by default.
64
65 setsebool -P authlogin_nsswitch_use_ldap 1
66
67
68
69 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71
72 setsebool -P fips_mode 1
73
74
75
76 If you want to allow confined applications to run with kerberos, you
77 must turn on the kerberos_enabled boolean. Disabled by default.
78
79 setsebool -P kerberos_enabled 1
80
81
82
83 If you want to allow nagios/nrpe to call sudo from NRPE utils scripts,
84 you must turn on the nagios_run_sudo boolean. Disabled by default.
85
86 setsebool -P nagios_run_sudo 1
87
88
89
90 If you want to allow system to run with NIS, you must turn on the
91 nis_enabled boolean. Disabled by default.
92
93 setsebool -P nis_enabled 1
94
95
96
97 If you want to allow confined applications to use nscd shared memory,
98 you must turn on the nscd_use_shm boolean. Disabled by default.
99
100 setsebool -P nscd_use_shm 1
101
102
103
104 If you want to allow Zabbix to run su/sudo, you must turn on the zab‐
105 bix_run_sudo boolean. Disabled by default.
106
107 setsebool -P zabbix_run_sudo 1
108
109
110
111 If you want to allow ZoneMinder to run su/sudo, you must turn on the
112 zoneminder_run_sudo boolean. Disabled by default.
113
114 setsebool -P zoneminder_run_sudo 1
115

117
119 The SELinux process type systemd_logind_t can manage files labeled with
120 the following file types. The paths listed are the default paths for
121 these file types. Note the processes UID still need to have DAC per‐
122 missions.

233 SELinux requires files to have an extended attribute to define the file
234 type.
235
236 You can see the context of a file using the -Z option to ls
237
238 Policy governs the access confined processes have to these files.
239 SELinux systemd_logind policy is very flexible allowing users to setup
240 their systemd_logind processes in as secure a method as possible.
241
242 STANDARD FILE CONTEXT
243
244 SELinux defines the file context types for the systemd_logind, if you
245 wanted to store files with these types in a diffent paths, you need to
246 execute the semanage command to sepecify alternate labeling and then
247 use restorecon to put the labels on disk.
248
249 semanage fcontext -a -t systemd_logind_inhibit_var_run_t '/srv/mysys‐
250 temd_logind_content(/.*)?'
251 restorecon -R -v /srv/mysystemd_logind_content
252
253 Note: SELinux often uses regular expressions to specify labels that
254 match multiple files.
255
256 The following file types are defined for systemd_logind:
257
258
259
260 systemd_logind_exec_t
261
262 - Set files with the systemd_logind_exec_t type, if you want to transi‐
263 tion an executable to the systemd_logind_t domain.
264
265
266 Paths:
267 /usr/lib/systemd/systemd-logind, /usr/lib/systemd/systemd-user-
268 runtime-dir
269
270
271 systemd_logind_inhibit_var_run_t
272
273 - Set files with the systemd_logind_inhibit_var_run_t type, if you want
274 to store the systemd logind inhibit files under the /run or /var/run
275 directory.
276
277
278
279 systemd_logind_sessions_t
280
281 - Set files with the systemd_logind_sessions_t type, if you want to
282 treat the files as systemd logind sessions data.
283
284
285
286 systemd_logind_var_lib_t
287
288 - Set files with the systemd_logind_var_lib_t type, if you want to
289 store the systemd logind files under the /var/lib directory.
290
291
292
293 systemd_logind_var_run_t
294
295 - Set files with the systemd_logind_var_run_t type, if you want to
296 store the systemd logind files under the /run or /var/run directory.
297
298
299 Paths:
300 /var/run/.*nologin.*, /var/run/systemd/seats(/.*)?, /var/run/sys‐
301 temd/users(/.*)?, /var/run/systemd/shutdown(/.*)?
302
303
304 Note: File context can be temporarily modified with the chcon command.
305 If you want to permanently change the file context you need to use the
306 semanage fcontext command. This will modify the SELinux labeling data‐
307 base. You will need to use restorecon to apply the labels.
308
309
311 semanage fcontext can also be used to manipulate default file context
312 mappings.
313
314 semanage permissive can also be used to manipulate whether or not a
315 process type is permissive.
316
317 semanage module can also be used to enable/disable/install/remove pol‐
318 icy modules.
319
320 semanage boolean can also be used to manipulate the booleans
321
322
323 system-config-selinux is a GUI tool available to customize SELinux pol‐
324 icy settings.
