6 systemd_hostnamed_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_hostnamed processes
8
10 Security-Enhanced Linux secures the systemd_hostnamed processes via
11 flexible mandatory access control.
12 The systemd_hostnamed processes execute with the systemd_hostnamed_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_hostnamed_t
20
24 The systemd_hostnamed_t SELinux type can be entered via the sys‐
25 temd_hostnamed_exec_t file type.
26 The default entrypoint paths for the systemd_hostnamed_t domain are the
28 following:
29 /usr/lib/systemd/systemd-hostnamed
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_hostnamed policy is very flexible allowing users to setup their
40 systemd_hostnamed processes in as secure a method as possible.
41 The following process types are defined for systemd_hostnamed:
43 systemd_hostnamed_t
45 Note: semanage permissive -a systemd_hostnamed_t can be used to make
47 the process type systemd_hostnamed_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_hostnamed policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run systemd_hostnamed with
56 the tightest access possible.
57 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 setsebool -P authlogin_nsswitch_use_ldap 1
65 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 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 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 setsebool -P nscd_use_shm 1
93
97 The SELinux process type systemd_hostnamed_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.

144 SELinux requires files to have an extended attribute to define the file
145 type.
146 You can see the context of a file using the -Z option to ls
148 Policy governs the access confined processes have to these files.
150 SELinux systemd_hostnamed policy is very flexible allowing users to
151 setup their systemd_hostnamed processes in as secure a method as possi‐
152 ble.
153 The following file types are defined for systemd_hostnamed:
155 systemd_hostnamed_exec_t
159 - Set files with the systemd_hostnamed_exec_t type, if you want to
161 transition an executable to the systemd_hostnamed_t domain.
162 Note: File context can be temporarily modified with the chcon command.
166 If you want to permanently change the file context you need to use the
167 semanage fcontext command. This will modify the SELinux labeling data‐
168 base. You will need to use restorecon to apply the labels.
169
172 semanage fcontext can also be used to manipulate default file context
173 mappings.
174 semanage permissive can also be used to manipulate whether or not a
176 process type is permissive.
177 semanage module can also be used to enable/disable/install/remove pol‐
179 icy modules.
180 semanage boolean can also be used to manipulate the booleans
182 system-config-selinux is a GUI tool available to customize SELinux pol‐
185 icy settings.
