NAME

6       systemd_logind_selinux  -  Security  Enhanced Linux Policy for the sys‐
7       temd_logind processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the systemd_logind processes via flexi‐
11       ble mandatory access control.
12
13       The  systemd_logind processes execute with the systemd_logind_t SELinux
14       type. You can check if you have these processes  running  by  executing
15       the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep systemd_logind_t
20
21
22

ENTRYPOINTS

24       The   systemd_logind_t  SELinux  type  can  be  entered  via  the  sys‐
25       temd_logind_exec_t file type.
26
27       The default entrypoint paths for the systemd_logind_t  domain  are  the
28       following:
29
30       /usr/lib/systemd/systemd-logind
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_logind  policy  is  very flexible allowing users to setup their
40       systemd_logind processes in as secure a method as possible.
41
42       The following process types are defined for systemd_logind:
43
44       systemd_logind_t
45
46       Note: semanage permissive -a systemd_logind_t can be used to  make  the
47       process  type systemd_logind_t permissive. SELinux does not deny access
48       to permissive process types, but the AVC (SELinux denials) messages are
49       still generated.
50
51

BOOLEANS

53       SELinux  policy  is  customizable based on least access required.  sys‐
54       temd_logind policy is extremely flexible and has several booleans  that
55       allow  you  to  manipulate  the  policy and run systemd_logind with the
56       tightest access possible.

FILE CONTEXTS

302       SELinux requires files to have an extended attribute to define the file
303       type.
304
305       You can see the context of a file using the -Z option to ls
306
307       Policy  governs  the  access  confined  processes  have to these files.
308       SELinux systemd_logind policy is very flexible allowing users to  setup
309       their systemd_logind processes in as secure a method as possible.
310
311       STANDARD FILE CONTEXT
312
313       SELinux  defines  the file context types for the systemd_logind, if you
314       wanted to store files with these types in a diffent paths, you need  to
315       execute  the  semanage  command to sepecify alternate labeling and then
316       use restorecon to put the labels on disk.
317
318       semanage   fcontext   -a   -t   systemd_logind_var_run_t   '/srv/mysys‐
319       temd_logind_content(/.*)?'
320       restorecon -R -v /srv/mysystemd_logind_content
321
322       Note:  SELinux  often  uses  regular expressions to specify labels that
323       match multiple files.
324
325       The following file types are defined for systemd_logind:
326
327
328
329       systemd_logind_exec_t
330
331       - Set files with the systemd_logind_exec_t type, if you want to transi‐
332       tion an executable to the systemd_logind_t domain.
333
334
335
336       systemd_logind_inhibit_var_run_t
337
338       - Set files with the systemd_logind_inhibit_var_run_t type, if you want
339       to store the systemd logind inhibit files under the  /run  or  /var/run
340       directory.
341
342
343
344       systemd_logind_sessions_t
345
346       -  Set  files  with  the systemd_logind_sessions_t type, if you want to
347       treat the files as systemd logind sessions data.
348
349
350
351       systemd_logind_var_lib_t
352
353       - Set files with the systemd_logind_var_lib_t  type,  if  you  want  to
354       store the systemd logind files under the /var/lib directory.
355
356
357
358       systemd_logind_var_run_t
359
360       -  Set  files  with  the  systemd_logind_var_run_t type, if you want to
361       store the systemd logind files under the /run or /var/run directory.
362
363
364       Paths:
365            /var/run/systemd/seats(/.*)?,        /var/run/systemd/users(/.*)?,
366            /var/run/nologin
367
368
369       Note:  File context can be temporarily modified with the chcon command.
370       If you want to permanently change the file context you need to use  the
371       semanage fcontext command.  This will modify the SELinux labeling data‐
372       base.  You will need to use restorecon to apply the labels.
373
374

COMMANDS

376       semanage fcontext can also be used to manipulate default  file  context
377       mappings.
378
379       semanage  permissive  can  also  be used to manipulate whether or not a
380       process type is permissive.
381
382       semanage module can also be used to enable/disable/install/remove  pol‐
383       icy modules.
384
385       semanage boolean can also be used to manipulate the booleans
386
387
388       system-config-selinux is a GUI tool available to customize SELinux pol‐
389       icy settings.
