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 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 For example:
18 ps -eZ | grep systemd_networkd_t
20
24 The systemd_networkd_t SELinux type can be entered via the systemd_net‐
25 workd_exec_t file type.
26 The default entrypoint paths for the systemd_networkd_t domain are the
28 following:
29 /usr/lib/systemd/systemd-networkd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for systemd_networkd:
43 systemd_networkd_t
45 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
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 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type systemd_networkd_t can manage files labeled
76 with the following file types. The paths listed are the default paths
77 for these file types. Note the processes UID still need to have DAC
78 permissions.

121 SELinux requires files to have an extended attribute to define the file
122 type.
123 You can see the context of a file using the -Z option to ls
125 Policy governs the access confined processes have to these files.
127 SELinux systemd_networkd policy is very flexible allowing users to set‐
128 up their systemd_networkd processes in as secure a method as possible.
129 STANDARD FILE CONTEXT
131 SELinux defines the file context types for the systemd_networkd, if you
133 wanted to store files with these types in a diffent paths, you need to
134 execute the semanage command to sepecify alternate labeling and then
135 use restorecon to put the labels on disk.
136 semanage fcontext -a -t systemd_networkd_var_run_t '/srv/mysystemd_net‐
138 workd_content(/.*)?'
139 restorecon -R -v /srv/mysystemd_networkd_content
140 Note: SELinux often uses regular expressions to specify labels that
142 match multiple files.
143 The following file types are defined for systemd_networkd:
145 systemd_networkd_exec_t
149 - Set files with the systemd_networkd_exec_t type, if you want to tran‐
151 sition an executable to the systemd_networkd_t domain.
152 systemd_networkd_unit_file_t
156 - Set files with the systemd_networkd_unit_file_t type, if you want to
158 treat the files as systemd networkd unit content.
159 systemd_networkd_var_run_t
163 - Set files with the systemd_networkd_var_run_t type, if you want to
165 store the systemd networkd files under the /run or /var/run directory.
166 Note: File context can be temporarily modified with the chcon command.
170 If you want to permanently change the file context you need to use the
171 semanage fcontext command. This will modify the SELinux labeling data‐
172 base. You will need to use restorecon to apply the labels.
173
176 semanage fcontext can also be used to manipulate default file context
177 mappings.
178 semanage permissive can also be used to manipulate whether or not a
180 process type is permissive.
181 semanage module can also be used to enable/disable/install/remove pol‐
183 icy modules.
184 semanage boolean can also be used to manipulate the booleans
186 system-config-selinux is a GUI tool available to customize SELinux pol‐
189 icy settings.
