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 sys‐
25 temd_notify_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 allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐

109 If you want to allow all domains write to kmsg_device, while kernel is
113 executed with systemd.log_target=kmsg parameter, you must turn on the
114 domain_can_write_kmsg boolean. Disabled by default.
115 setsebool -P domain_can_write_kmsg 1
117 If you want to allow all domains to use other domains file descriptors,
121 you must turn on the domain_fd_use boolean. Enabled by default.
122 setsebool -P domain_fd_use 1
124 If you want to allow all domains to have the kernel load modules, you
128 must turn on the domain_kernel_load_modules boolean. Disabled by
129 default.
130 setsebool -P domain_kernel_load_modules 1
132 If you want to allow all domains to execute in fips_mode, you must turn
136 on the fips_mode boolean. Enabled by default.
137 setsebool -P fips_mode 1
139 If you want to enable reading of urandom for all domains, you must turn
143 on the global_ssp boolean. Disabled by default.
144 setsebool -P global_ssp 1
146 If you want to allow confined applications to run with kerberos, you
150 must turn on the kerberos_enabled boolean. Enabled by default.
151 setsebool -P kerberos_enabled 1
153 If you want to allow system to run with NIS, you must turn on the
157 nis_enabled boolean. Disabled by default.
158 setsebool -P nis_enabled 1
160 If you want to allow confined applications to use nscd shared memory,
164 you must turn on the nscd_use_shm boolean. Disabled by default.
165 setsebool -P nscd_use_shm 1

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.

219 SELinux requires files to have an extended attribute to define the file
220 type.
221 You can see the context of a file using the -Z option to ls
223 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 The following file types are defined for systemd_notify:
229 systemd_notify_exec_t
233 - 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 Paths:
239 /bin/systemd-notify, /usr/bin/systemd-notify
240 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
249 semanage fcontext can also be used to manipulate default file context
250 mappings.
251 semanage permissive can also be used to manipulate whether or not a
253 process type is permissive.
254 semanage module can also be used to enable/disable/install/remove pol‐
256 icy modules.
257 semanage boolean can also be used to manipulate the booleans
259 system-config-selinux is a GUI tool available to customize SELinux pol‐
262 icy settings.
