NAME

6       systemd_notify_selinux  -  Security  Enhanced Linux Policy for the sys‐
7       temd_notify processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the systemd_notify processes via flexi‐
11       ble mandatory access control.
12
13       The  systemd_notify processes execute with the systemd_notify_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_notify_t
20
21
22

ENTRYPOINTS

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

51

BOOLEANS

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

MANAGED FILES

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

FILE CONTEXTS

219       SELinux requires files to have an extended attribute to define the file
220       type.
221
222       You can see the context of a file using the -Z option to ls
223
224       Policy governs the access  confined  processes  have  to  these  files.
225       SELinux  systemd_notify policy is very flexible allowing users to setup
226       their systemd_notify processes in as secure a method as possible.
227
228       The following file types are defined for systemd_notify:
229
230
231
232       systemd_notify_exec_t
233
234       - Set files with the systemd_notify_exec_t type, if you want to transi‐
235       tion an executable to the systemd_notify_t domain.
236
237
238       Paths:
239            /bin/systemd-notify, /usr/bin/systemd-notify
240
241
242       Note:  File context can be temporarily modified with the chcon command.
243       If you want to permanently change the file context you need to use  the
244       semanage fcontext command.  This will modify the SELinux labeling data‐
245       base.  You will need to use restorecon to apply the labels.
246
247

COMMANDS

249       semanage fcontext can also be used to manipulate default  file  context
250       mappings.
251
252       semanage  permissive  can  also  be used to manipulate whether or not a
253       process type is permissive.
254
255       semanage module can also be used to enable/disable/install/remove  pol‐
256       icy modules.
257
258       semanage boolean can also be used to manipulate the booleans
259
260
261       system-config-selinux is a GUI tool available to customize SELinux pol‐
262       icy settings.
