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
13 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
17 For example:
18
19 ps -eZ | grep systemd_userdbd_t
20
21
22
24 The systemd_userdbd_t SELinux type can be entered via the sys‐
25 temd_userdbd_exec_t file type.
26
27 The default entrypoint paths for the systemd_userdbd_t domain are the
28 following:
29
30 /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
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_userdbd policy is very flexible allowing users to setup their
40 systemd_userdbd processes in as secure a method as possible.
41
42 The following process types are defined for systemd_userdbd:
43
44 systemd_userdbd_t
45
46 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
51
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
58
59
60 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 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 system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77
78 setsebool -P nis_enabled 1

81
83 The SELinux process type systemd_userdbd_t can manage files labeled
84 with the following file types. The paths listed are the default paths
85 for these file types. Note the processes UID still need to have DAC
86 permissions.

144 SELinux requires files to have an extended attribute to define the file
145 type.
146
147 You can see the context of a file using the -Z option to ls
148
149 Policy governs the access confined processes have to these files.
150 SELinux systemd_userdbd policy is very flexible allowing users to setup
151 their systemd_userdbd processes in as secure a method as possible.
152
153 STANDARD FILE CONTEXT
154
155 SELinux defines the file context types for the systemd_userdbd, if you
156 wanted to store files with these types in a different paths, you need
157 to execute the semanage command to specify alternate labeling and then
158 use restorecon to put the labels on disk.
159
160 semanage fcontext -a -t systemd_userdbd_exec_t '/srv/sys‐
161 temd_userdbd/content(/.*)?'
162 restorecon -R -v /srv/mysystemd_userdbd_content
163
164 Note: SELinux often uses regular expressions to specify labels that
165 match multiple files.
166
167 The following file types are defined for systemd_userdbd:
168
169
170
171 systemd_userdbd_exec_t
172
173 - Set files with the systemd_userdbd_exec_t type, if you want to tran‐
174 sition an executable to the systemd_userdbd_t domain.
175
176
177 Paths:
178 /usr/lib/systemd/systemd-userdbd, /usr/lib/systemd/systemd-user‐
179 work
180
181
182 systemd_userdbd_runtime_t
183
184 - Set files with the systemd_userdbd_runtime_t type, if you want to
185 treat the files as systemd userdbd runtime data.
186
187
188
189 systemd_userdbd_unit_file_t
190
191 - Set files with the systemd_userdbd_unit_file_t type, if you want to
192 treat the files as systemd userdbd unit content.
193
194
195
196 Note: File context can be temporarily modified with the chcon command.
197 If you want to permanently change the file context you need to use the
198 semanage fcontext command. This will modify the SELinux labeling data‐
199 base. You will need to use restorecon to apply the labels.
200
201
203 semanage fcontext can also be used to manipulate default file context
204 mappings.
205
206 semanage permissive can also be used to manipulate whether or not a
207 process type is permissive.
208
209 semanage module can also be used to enable/disable/install/remove pol‐
210 icy modules.
211
212 semanage boolean can also be used to manipulate the booleans
213
214
215 system-config-selinux is a GUI tool available to customize SELinux pol‐
216 icy settings.
