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.

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_userdbd policy is very flexible allowing users to setup
128 their systemd_userdbd processes in as secure a method as possible.
129 STANDARD FILE CONTEXT
131 SELinux defines the file context types for the systemd_userdbd, 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_userdbd_runtime_t '/srv/mysys‐
138 temd_userdbd_content(/.*)?'
139 restorecon -R -v /srv/mysystemd_userdbd_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_userdbd:
145 systemd_userdbd_exec_t
149 - Set files with the systemd_userdbd_exec_t type, if you want to tran‐
151 sition an executable to the systemd_userdbd_t domain.
152 Paths:
155 /usr/lib/systemd/systemd-userdbd, /usr/lib/systemd/systemd-user‐
156 work
157 systemd_userdbd_runtime_t
160 - Set files with the systemd_userdbd_runtime_t type, if you want to
162 treat the files as systemd userdbd runtime data.
163 systemd_userdbd_unit_file_t
167 - Set files with the systemd_userdbd_unit_file_t type, if you want to
169 treat the files as systemd userdbd unit content.
170 Note: File context can be temporarily modified with the chcon command.
174 If you want to permanently change the file context you need to use the
175 semanage fcontext command. This will modify the SELinux labeling data‐
176 base. You will need to use restorecon to apply the labels.
177
180 semanage fcontext can also be used to manipulate default file context
181 mappings.
182 semanage permissive can also be used to manipulate whether or not a
184 process type is permissive.
185 semanage module can also be used to enable/disable/install/remove pol‐
187 icy modules.
188 semanage boolean can also be used to manipulate the booleans
190 system-config-selinux is a GUI tool available to customize SELinux pol‐
193 icy settings.
