6 systemd_userdbd_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_userdbd processes
8
10 Security-Enhanced Linux secures the systemd_userdbd processes via flex‐
11 ible mandatory access control.
12 The systemd_userdbd processes execute with the systemd_userdbd_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_userdbd_t
20
24 The systemd_userdbd_t SELinux type can be entered via the sys‐
25 temd_userdbd_exec_t file type.
26 The default entrypoint paths for the systemd_userdbd_t domain are the
28 following:
29 /usr/lib/systemd/systemd-userdbd, /usr/lib/systemd/systemd-userwork
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_userdbd policy is very flexible allowing users to setup their
40 systemd_userdbd processes in as secure a method as possible.
41 The following process types are defined for systemd_userdbd:
43 systemd_userdbd_t
45 Note: semanage permissive -a systemd_userdbd_t can be used to make the
47 process type systemd_userdbd_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. sys‐
54 temd_userdbd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run systemd_userdbd with the
56 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_userdbd_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.

136 SELinux requires files to have an extended attribute to define the file
137 type.
138 You can see the context of a file using the -Z option to ls
140 Policy governs the access confined processes have to these files.
142 SELinux systemd_userdbd policy is very flexible allowing users to setup
143 their systemd_userdbd processes in as secure a method as possible.
144 STANDARD FILE CONTEXT
146 SELinux defines the file context types for the systemd_userdbd, if you
148 wanted to store files with these types in a diffent paths, you need to
149 execute the semanage command to sepecify alternate labeling and then
150 use restorecon to put the labels on disk.
151 semanage fcontext -a -t systemd_userdbd_runtime_t '/srv/mysys‐
153 temd_userdbd_content(/.*)?'
154 restorecon -R -v /srv/mysystemd_userdbd_content
155 Note: SELinux often uses regular expressions to specify labels that
157 match multiple files.
158 The following file types are defined for systemd_userdbd:
160 systemd_userdbd_exec_t
164 - Set files with the systemd_userdbd_exec_t type, if you want to tran‐
166 sition an executable to the systemd_userdbd_t domain.
167 Paths:
170 /usr/lib/systemd/systemd-userdbd, /usr/lib/systemd/systemd-user‐
171 work
172 systemd_userdbd_runtime_t
175 - Set files with the systemd_userdbd_runtime_t type, if you want to
177 treat the files as systemd userdbd runtime data.
178 systemd_userdbd_unit_file_t
182 - Set files with the systemd_userdbd_unit_file_t type, if you want to
184 treat the files as systemd userdbd unit content.
185 Note: File context can be temporarily modified with the chcon command.
189 If you want to permanently change the file context you need to use the
190 semanage fcontext command. This will modify the SELinux labeling data‐
191 base. You will need to use restorecon to apply the labels.
192
195 semanage fcontext can also be used to manipulate default file context
196 mappings.
197 semanage permissive can also be used to manipulate whether or not a
199 process type is permissive.
200 semanage module can also be used to enable/disable/install/remove pol‐
202 icy modules.
203 semanage boolean can also be used to manipulate the booleans
205 system-config-selinux is a GUI tool available to customize SELinux pol‐
208 icy settings.
