NAME

6       systemd_hostnamed_selinux - Security Enhanced Linux Policy for the sys‐
7       temd_hostnamed processes
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  systemd_hostnamed  processes  via
11       flexible mandatory access control.
12
13       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
17       For example:
18
19       ps -eZ | grep systemd_hostnamed_t
20
21
22

ENTRYPOINTS

24       The  systemd_hostnamed_t  SELinux  type  can  be  entered  via the sys‐
25       temd_hostnamed_exec_t file type.
26
27       The default entrypoint paths for the systemd_hostnamed_t domain are the
28       following:
29
30       /usr/lib/systemd/systemd-hostnamed
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_hostnamed policy is very flexible allowing users to setup their
40       systemd_hostnamed processes in as secure a method as possible.
41
42       The following process types are defined for systemd_hostnamed:
43
44       systemd_hostnamed_t
45
46       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
51

BOOLEANS

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.

MANAGED FILES

171       The SELinux process type systemd_hostnamed_t can manage  files  labeled
172       with  the following file types.  The paths listed are the default paths
173       for these file types.  Note the processes UID still need  to  have  DAC
174       permissions.

FILE CONTEXTS

218       SELinux requires files to have an extended attribute to define the file
219       type.
220
221       You can see the context of a file using the -Z option to ls
222
223       Policy governs the access  confined  processes  have  to  these  files.
224       SELinux  systemd_hostnamed  policy  is  very flexible allowing users to
225       setup their systemd_hostnamed processes in as secure a method as possi‐
226       ble.
227
228       The following file types are defined for systemd_hostnamed:
229
230
231
232       systemd_hostnamed_exec_t
233
234       -  Set  files  with  the  systemd_hostnamed_exec_t type, if you want to
235       transition an executable to the systemd_hostnamed_t domain.
236
237
238
239       Note: File context can be temporarily modified with the chcon  command.
240       If  you want to permanently change the file context you need to use the
241       semanage fcontext command.  This will modify the SELinux labeling data‐
242       base.  You will need to use restorecon to apply the labels.
243
244

COMMANDS

246       semanage  fcontext  can also be used to manipulate default file context
247       mappings.
248
249       semanage permissive can also be used to manipulate  whether  or  not  a
250       process type is permissive.
251
252       semanage  module can also be used to enable/disable/install/remove pol‐
253       icy modules.
254
255       semanage boolean can also be used to manipulate the booleans
256
257
258       system-config-selinux is a GUI tool available to customize SELinux pol‐
259       icy settings.
