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 sys‐
25 temd_machined_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
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_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 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. Enabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type systemd_machined_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.

147 SELinux requires files to have an extended attribute to define the file
148 type.
149
150 You can see the context of a file using the -Z option to ls
151
152 Policy governs the access confined processes have to these files.
153 SELinux systemd_machined policy is very flexible allowing users to set‐
154 up their systemd_machined processes in as secure a method as possible.
155
156 STANDARD FILE CONTEXT
157
158 SELinux defines the file context types for the systemd_machined, if you
159 wanted to store files with these types in a diffent paths, you need to
160 execute the semanage command to sepecify alternate labeling and then
161 use restorecon to put the labels on disk.
162
163 semanage fcontext -a -t systemd_machined_var_lib_t '/srv/mysys‐
164 temd_machined_content(/.*)?'
165 restorecon -R -v /srv/mysystemd_machined_content
166
167 Note: SELinux often uses regular expressions to specify labels that
168 match multiple files.
169
170 The following file types are defined for systemd_machined:
171
172
173
174 systemd_machined_exec_t
175
176 - Set files with the systemd_machined_exec_t type, if you want to tran‐
177 sition an executable to the systemd_machined_t domain.
178
179
180
181 systemd_machined_unit_file_t
182
183 - Set files with the systemd_machined_unit_file_t type, if you want to
184 treat the files as systemd machined unit content.
185
186
187
188 systemd_machined_var_lib_t
189
190 - Set files with the systemd_machined_var_lib_t type, if you want to
191 store the systemd machined files under the /var/lib directory.
192
193
194
195 systemd_machined_var_run_t
196
197 - Set files with the systemd_machined_var_run_t type, if you want to
198 store the systemd machined files under the /run or /var/run directory.
199
200
201
202 Note: File context can be temporarily modified with the chcon command.
203 If you want to permanently change the file context you need to use the
204 semanage fcontext command. This will modify the SELinux labeling data‐
205 base. You will need to use restorecon to apply the labels.
206
207
209 semanage fcontext can also be used to manipulate default file context
210 mappings.
211
212 semanage permissive can also be used to manipulate whether or not a
213 process type is permissive.
214
215 semanage module can also be used to enable/disable/install/remove pol‐
216 icy modules.
217
218 semanage boolean can also be used to manipulate the booleans
219
220
221 system-config-selinux is a GUI tool available to customize SELinux pol‐
222 icy settings.
