NAME

6       systemd_machined_selinux  - Security Enhanced Linux Policy for the sys‐
7       temd_machined processes
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  systemd_machined  processes  via
11       flexible mandatory access control.
12
13       The  systemd_machined  processes  execute  with  the systemd_machined_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_machined_t
20
21
22

ENTRYPOINTS

24       The  systemd_machined_t  SELinux  type  can  be  entered  via  the sys‐
25       temd_machined_exec_t file type.
26
27       The default entrypoint paths for the systemd_machined_t domain are  the
28       following:
29
30       /usr/lib/systemd/systemd-machined
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_machined  policy is very flexible allowing users to setup their
40       systemd_machined processes in as secure a method as possible.
41
42       The following process types are defined for systemd_machined:
43
44       systemd_machined_t
45
46       Note: semanage permissive -a systemd_machined_t can be used to make the
47       process  type  systemd_machined_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_machined policy is extremely flexible  and  has  several  booleans
55       that  allow  you to manipulate the policy and run systemd_machined with
56       the tightest access possible.

MANAGED FILES

171       The SELinux process type systemd_machined_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

221       SELinux requires files to have an extended attribute to define the file
222       type.
223
224       You can see the context of a file using the -Z option to ls
225
226       Policy governs the access  confined  processes  have  to  these  files.
227       SELinux systemd_machined policy is very flexible allowing users to set‐
228       up their systemd_machined processes in as secure a method as possible.
229
230       STANDARD FILE CONTEXT
231
232       SELinux defines the file context types for the systemd_machined, if you
233       wanted  to store files with these types in a diffent paths, you need to
234       execute the semanage command to sepecify alternate  labeling  and  then
235       use restorecon to put the labels on disk.
236
237       semanage   fcontext   -a   -t  systemd_machined_var_run_t  '/srv/mysys‐
238       temd_machined_content(/.*)?'
239       restorecon -R -v /srv/mysystemd_machined_content
240
241       Note: SELinux often uses regular expressions  to  specify  labels  that
242       match multiple files.
243
244       The following file types are defined for systemd_machined:
245
246
247
248       systemd_machined_exec_t
249
250       - Set files with the systemd_machined_exec_t type, if you want to tran‐
251       sition an executable to the systemd_machined_t domain.
252
253
254
255       systemd_machined_unit_file_t
256
257       - Set files with the systemd_machined_unit_file_t type, if you want  to
258       treat the files as systemd machined unit content.
259
260
261
262       systemd_machined_var_lib_t
263
264       -  Set  files  with the systemd_machined_var_lib_t type, if you want to
265       store the systemd machined files under the /var/lib directory.
266
267
268
269       systemd_machined_var_run_t
270
271       - Set files with the systemd_machined_var_run_t type, if  you  want  to
272       store the systemd machined files under the /run or /var/run directory.
273
274
275
276       Note:  File context can be temporarily modified with the chcon command.
277       If you want to permanently change the file context you need to use  the
278       semanage fcontext command.  This will modify the SELinux labeling data‐
279       base.  You will need to use restorecon to apply the labels.
280
281

COMMANDS

283       semanage fcontext can also be used to manipulate default  file  context
284       mappings.
285
286       semanage  permissive  can  also  be used to manipulate whether or not a
287       process type is permissive.
288
289       semanage module can also be used to enable/disable/install/remove  pol‐
290       icy modules.
291
292       semanage boolean can also be used to manipulate the booleans
293
294
295       system-config-selinux is a GUI tool available to customize SELinux pol‐
296       icy settings.
