6 systemd_machined_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_machined processes
8
10 Security-Enhanced Linux secures the systemd_machined processes via
11 flexible mandatory access control.
12
13 The systemd_machined processes execute with the systemd_machined_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_machined_t
20
21
22
24 The systemd_machined_t SELinux type can be entered via the systemd_ma‐
25 chined_exec_t file type.
26
27 The default entrypoint paths for the systemd_machined_t domain are the
28 following:
29
30 /usr/lib/systemd/systemd-machined
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_machined policy is very flexible allowing users to setup their
40 systemd_machined processes in as secure a method as possible.
41
42 The following process types are defined for systemd_machined:
43
44 systemd_machined_t
45
46 Note: semanage permissive -a systemd_machined_t can be used to make the
47 process type systemd_machined_t permissive. SELinux does not deny ac‐
48 cess 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_machined policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run systemd_machined with
56 the tightest access possible.
57
58
59
60 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 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 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

81
83 The SELinux process type systemd_machined_t can manage files labeled
84 with the following file types. The paths listed are the default paths
85 for these file types. Note the processes UID still need to have DAC
86 permissions.

154 SELinux requires files to have an extended attribute to define the file
155 type.
156
157 You can see the context of a file using the -Z option to ls
158
159 Policy governs the access confined processes have to these files.
160 SELinux systemd_machined policy is very flexible allowing users to
161 setup their systemd_machined processes in as secure a method as possi‐
162 ble.
163
164 EQUIVALENCE DIRECTORIES
165
166
167 systemd_machined policy stores data with multiple different file con‐
168 text types under the /var/run/systemd/machines directory. If you would
169 like to store the data in a different directory you can use the seman‐
170 age command to create an equivalence mapping. If you wanted to store
171 this data under the /srv directory you would execute the following com‐
172 mand:
173
174 semanage fcontext -a -e /var/run/systemd/machines /srv/machines
175 restorecon -R -v /srv/machines
176
177 STANDARD FILE CONTEXT
178
179 SELinux defines the file context types for the systemd_machined, if you
180 wanted to store files with these types in a different paths, you need
181 to execute the semanage command to specify alternate labeling and then
182 use restorecon to put the labels on disk.
183
184 semanage fcontext -a -t systemd_machined_exec_t '/srv/systemd_ma‐
185 chined/content(/.*)?'
186 restorecon -R -v /srv/mysystemd_machined_content
187
188 Note: SELinux often uses regular expressions to specify labels that
189 match multiple files.
190
191 The following file types are defined for systemd_machined:
192
193
194
195 systemd_machined_exec_t
196
197 - Set files with the systemd_machined_exec_t type, if you want to tran‐
198 sition an executable to the systemd_machined_t domain.
199
200
201
202 systemd_machined_unit_file_t
203
204 - Set files with the systemd_machined_unit_file_t type, if you want to
205 treat the files as systemd machined unit content.
206
207
208
209 systemd_machined_var_lib_t
210
211 - Set files with the systemd_machined_var_lib_t type, if you want to
212 store the systemd machined files under the /var/lib directory.
213
214
215
216 systemd_machined_var_run_t
217
218 - Set files with the systemd_machined_var_run_t type, if you want to
219 store the systemd machined files under the /run or /var/run directory.
220
221
222 Paths:
223 /var/run/systemd/machines.lock, /var/run/systemd/machines(/.*)?
224
225
226 Note: File context can be temporarily modified with the chcon command.
227 If you want to permanently change the file context you need to use the
228 semanage fcontext command. This will modify the SELinux labeling data‐
229 base. You will need to use restorecon to apply the labels.
230
231
233 semanage fcontext can also be used to manipulate default file context
234 mappings.
235
236 semanage permissive can also be used to manipulate whether or not a
237 process type is permissive.
238
239 semanage module can also be used to enable/disable/install/remove pol‐
240 icy modules.
241
242 semanage boolean can also be used to manipulate the booleans
243
244
245 system-config-selinux is a GUI tool available to customize SELinux pol‐
246 icy settings.
