6 systemd_networkd_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_networkd processes
8
10 Security-Enhanced Linux secures the systemd_networkd processes via
11 flexible mandatory access control.
12
13 The systemd_networkd processes execute with the systemd_networkd_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_networkd_t
20
21
22
24 The systemd_networkd_t SELinux type can be entered via the systemd_net‐
25 workd_exec_t file type.
26
27 The default entrypoint paths for the systemd_networkd_t domain are the
28 following:
29
30 /usr/lib/systemd/systemd-networkd
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_networkd policy is very flexible allowing users to setup their
40 systemd_networkd processes in as secure a method as possible.
41
42 The following process types are defined for systemd_networkd:
43
44 systemd_networkd_t
45
46 Note: semanage permissive -a systemd_networkd_t can be used to make the
47 process type systemd_networkd_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_networkd policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run systemd_networkd 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_networkd_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.

163 SELinux requires files to have an extended attribute to define the file
164 type.
165
166 You can see the context of a file using the -Z option to ls
167
168 Policy governs the access confined processes have to these files.
169 SELinux systemd_networkd policy is very flexible allowing users to set‐
170 up their systemd_networkd processes in as secure a method as possible.
171
172 STANDARD FILE CONTEXT
173
174 SELinux defines the file context types for the systemd_networkd, if you
175 wanted to store files with these types in a diffent paths, you need to
176 execute the semanage command to sepecify alternate labeling and then
177 use restorecon to put the labels on disk.
178
179 semanage fcontext -a -t systemd_networkd_var_run_t '/srv/mysystemd_net‐
180 workd_content(/.*)?'
181 restorecon -R -v /srv/mysystemd_networkd_content
182
183 Note: SELinux often uses regular expressions to specify labels that
184 match multiple files.
185
186 The following file types are defined for systemd_networkd:
187
188
189
190 systemd_networkd_exec_t
191
192 - Set files with the systemd_networkd_exec_t type, if you want to tran‐
193 sition an executable to the systemd_networkd_t domain.
194
195
196
197 systemd_networkd_unit_file_t
198
199 - Set files with the systemd_networkd_unit_file_t type, if you want to
200 treat the files as systemd networkd unit content.
201
202
203
204 systemd_networkd_var_run_t
205
206 - Set files with the systemd_networkd_var_run_t type, if you want to
207 store the systemd networkd files under the /run or /var/run directory.
208
209
210
211 Note: File context can be temporarily modified with the chcon command.
212 If you want to permanently change the file context you need to use the
213 semanage fcontext command. This will modify the SELinux labeling data‐
214 base. You will need to use restorecon to apply the labels.
215
216
218 semanage fcontext can also be used to manipulate default file context
219 mappings.
220
221 semanage permissive can also be used to manipulate whether or not a
222 process type is permissive.
223
224 semanage module can also be used to enable/disable/install/remove pol‐
225 icy modules.
226
227 semanage boolean can also be used to manipulate the booleans
228
229
230 system-config-selinux is a GUI tool available to customize SELinux pol‐
231 icy settings.
