NAME

6       systemd_resolved_selinux  - Security Enhanced Linux Policy for the sys‐
7       temd_resolved processes
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  systemd_resolved  processes  via
11       flexible mandatory access control.
12
13       The  systemd_resolved  processes  execute  with  the systemd_resolved_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_resolved_t

22

ENTRYPOINTS

24       The  systemd_resolved_t  SELinux  type  can  be  entered  via  the sys‐
25       temd_resolved_exec_t file type.
26
27       The default entrypoint paths for the systemd_resolved_t domain are  the
28       following:
29
30       /usr/lib/systemd/systemd-resolve(d|-host)
31

PROCESS TYPES

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_resolved  policy is very flexible allowing users to setup their
40       systemd_resolved processes in as secure a method as possible.
41
42       The following process types are defined for systemd_resolved:
43
44       systemd_resolved_t
45
46       Note: semanage permissive -a systemd_resolved_t can be used to make the
47       process  type  systemd_resolved_t  permissive.  SELinux  does  not deny
48       access to permissive process types, but the AVC (SELinux denials)  mes‐
49       sages are still generated.

51

BOOLEANS

53       SELinux  policy  is  customizable based on least access required.  sys‐
54       temd_resolved policy is extremely flexible  and  has  several  booleans
55       that  allow  you to manipulate the policy and run systemd_resolved with
56       the tightest access possible.
57
58
59
60       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
63       setsebool -P fips_mode 1

MANAGED FILES

68       The  SELinux  process  type systemd_resolved_t can manage files labeled
69       with the following file types.  The paths listed are the default  paths
70       for  these  file  types.  Note the processes UID still need to have DAC
71       permissions.
72
73       cluster_conf_t

75            /etc/cluster(/.*)?

FILE CONTEXTS

115       SELinux requires files to have an extended attribute to define the file
116       type.
117
118       You can see the context of a file using the -Z option to ls
119
120       Policy  governs  the  access  confined  processes  have to these files.
121       SELinux systemd_resolved policy is very flexible allowing users to set‐
122       up their systemd_resolved processes in as secure a method as possible.
123
124       STANDARD FILE CONTEXT
125
126       SELinux defines the file context types for the systemd_resolved, if you
127       wanted to store files with these types in a diffent paths, you need  to
128       execute  the  semanage  command to sepecify alternate labeling and then
129       use restorecon to put the labels on disk.
130
131       semanage  fcontext  -a  -t  systemd_resolved_unit_file_t   '/srv/mysys‐
132       temd_resolved_content(/.*)?'
133       restorecon -R -v /srv/mysystemd_resolved_content
134
135       Note:  SELinux  often  uses  regular expressions to specify labels that
136       match multiple files.
137
138       The following file types are defined for systemd_resolved:
139
140
141
142       systemd_resolved_exec_t
143
144       - Set files with the systemd_resolved_exec_t type, if you want to tran‐
145       sition an executable to the systemd_resolved_t domain.
146
147
148
149       systemd_resolved_unit_file_t
150
151       -  Set files with the systemd_resolved_unit_file_t type, if you want to
152       treat the files as systemd resolved unit content.
153
154
155
156       systemd_resolved_var_run_t
157
158       - Set files with the systemd_resolved_var_run_t type, if  you  want  to
159       store the systemd resolved files under the /run or /var/run directory.
160
161
162       Paths:
163            /run/systemd/resolve(/.*)?, /var/run/systemd/resolve(/.*)?
164
165
166       Note:  File context can be temporarily modified with the chcon command.
167       If you want to permanently change the file context you need to use  the
168       semanage fcontext command.  This will modify the SELinux labeling data‐
169       base.  You will need to use restorecon to apply the labels.

171

COMMANDS

173       semanage fcontext can also be used to manipulate default  file  context
174       mappings.
175
176       semanage  permissive  can  also  be used to manipulate whether or not a
177       process type is permissive.
178
179       semanage module can also be used to enable/disable/install/remove  pol‐
180       icy modules.
181
182       semanage boolean can also be used to manipulate the booleans
183
184
185       system-config-selinux is a GUI tool available to customize SELinux pol‐
186       icy settings.
