6 systemd_notify_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_notify processes
8
10 Security-Enhanced Linux secures the systemd_notify processes via flexi‐
11 ble mandatory access control.
12 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 For example:
18 ps -eZ | grep systemd_notify_t
20
24 The systemd_notify_t SELinux type can be entered via the systemd_no‐
25 tify_exec_t file type.
26 The default entrypoint paths for the systemd_notify_t domain are the
28 following:
29 /bin/systemd-notify, /usr/bin/systemd-notify
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for systemd_notify:
43 systemd_notify_t
45 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.
50
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.
57 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1
79
83 The SELinux process type systemd_notify_t can manage files labeled with
84 the following file types. The paths listed are the default paths for
85 these file types. Note the processes UID still need to have DAC per‐
86 missions.

146 SELinux requires files to have an extended attribute to define the file
147 type.
148 You can see the context of a file using the -Z option to ls
150 Policy governs the access confined processes have to these files.
152 SELinux systemd_notify policy is very flexible allowing users to setup
153 their systemd_notify processes in as secure a method as possible.
154 STANDARD FILE CONTEXT
156 SELinux defines the file context types for the systemd_notify, if you
158 wanted to store files with these types in a different paths, you need
159 to execute the semanage command to specify alternate labeling and then
160 use restorecon to put the labels on disk.
161 semanage fcontext -a -t systemd_notify_exec_t '/srv/systemd_notify/con‐
163 tent(/.*)?'
164 restorecon -R -v /srv/mysystemd_notify_content
165 Note: SELinux often uses regular expressions to specify labels that
167 match multiple files.
168 The following file types are defined for systemd_notify:
170 systemd_notify_exec_t
174 - Set files with the systemd_notify_exec_t type, if you want to transi‐
176 tion an executable to the systemd_notify_t domain.
177 Paths:
180 /bin/systemd-notify, /usr/bin/systemd-notify
181 Note: File context can be temporarily modified with the chcon command.
184 If you want to permanently change the file context you need to use the
185 semanage fcontext command. This will modify the SELinux labeling data‐
186 base. You will need to use restorecon to apply the labels.
187
190 semanage fcontext can also be used to manipulate default file context
191 mappings.
192 semanage permissive can also be used to manipulate whether or not a
194 process type is permissive.
195 semanage module can also be used to enable/disable/install/remove pol‐
197 icy modules.
198 semanage boolean can also be used to manipulate the booleans
200 system-config-selinux is a GUI tool available to customize SELinux pol‐
203 icy settings.
