6 systemd_timedated_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_timedated processes
8
10 Security-Enhanced Linux secures the systemd_timedated processes via
11 flexible mandatory access control.
12
13 The systemd_timedated processes execute with the systemd_timedated_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep systemd_timedated_t
20
21
22
24 The systemd_timedated_t SELinux type can be entered via the sys‐
25 temd_timedated_exec_t file type.
26
27 The default entrypoint paths for the systemd_timedated_t domain are the
28 following:
29
30 /usr/lib/systemd/systemd-timedated, /usr/lib/systemd/systemd-timesyncd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 systemd_timedated policy is very flexible allowing users to setup their
40 systemd_timedated processes in as secure a method as possible.
41
42 The following process types are defined for systemd_timedated:
43
44 systemd_timedated_t
45
46 Note: semanage permissive -a systemd_timedated_t can be used to make
47 the process type systemd_timedated_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
51
53 SELinux policy is customizable based on least access required. sys‐
54 temd_timedated policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run systemd_timedated with
56 the tightest access possible.
57
58
59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type systemd_timedated_t can manage files labeled
98 with the following file types. The paths listed are the default paths
99 for these file types. Note the processes UID still need to have DAC
100 permissions.

193 SELinux requires files to have an extended attribute to define the file
194 type.
195
196 You can see the context of a file using the -Z option to ls
197
198 Policy governs the access confined processes have to these files.
199 SELinux systemd_timedated policy is very flexible allowing users to
200 setup their systemd_timedated processes in as secure a method as possi‐
201 ble.
202
203 STANDARD FILE CONTEXT
204
205 SELinux defines the file context types for the systemd_timedated, if
206 you wanted to store files with these types in a diffent paths, you need
207 to execute the semanage command to sepecify alternate labeling and then
208 use restorecon to put the labels on disk.
209
210 semanage fcontext -a -t systemd_timedated_var_lib_t '/srv/mysys‐
211 temd_timedated_content(/.*)?'
212 restorecon -R -v /srv/mysystemd_timedated_content
213
214 Note: SELinux often uses regular expressions to specify labels that
215 match multiple files.
216
217 The following file types are defined for systemd_timedated:
218
219
220
221 systemd_timedated_exec_t
222
223 - Set files with the systemd_timedated_exec_t type, if you want to
224 transition an executable to the systemd_timedated_t domain.
225
226
227 Paths:
228 /usr/lib/systemd/systemd-timedated, /usr/lib/systemd/systemd-
229 timesyncd
230
231
232 systemd_timedated_unit_file_t
233
234 - Set files with the systemd_timedated_unit_file_t type, if you want to
235 treat the files as systemd timedated unit content.
236
237
238
239 systemd_timedated_var_lib_t
240
241 - Set files with the systemd_timedated_var_lib_t type, if you want to
242 store the systemd timedated files under the /var/lib directory.
243
244
245 Paths:
246 /var/lib/systemd/timesync(/.*)?, /var/lib/private/sys‐
247 temd/timesync(/.*)?
248
249
250 systemd_timedated_var_run_t
251
252 - Set files with the systemd_timedated_var_run_t type, if you want to
253 store the systemd timedated files under the /run or /var/run directory.
254
255
256
257 Note: File context can be temporarily modified with the chcon command.
258 If you want to permanently change the file context you need to use the
259 semanage fcontext command. This will modify the SELinux labeling data‐
260 base. You will need to use restorecon to apply the labels.
261
262
264 semanage fcontext can also be used to manipulate default file context
265 mappings.
266
267 semanage permissive can also be used to manipulate whether or not a
268 process type is permissive.
269
270 semanage module can also be used to enable/disable/install/remove pol‐
271 icy modules.
272
273 semanage boolean can also be used to manipulate the booleans
274
275
276 system-config-selinux is a GUI tool available to customize SELinux pol‐
277 icy settings.
