NAME¶
NetworkManager_dispatcher_selinux - Security Enhanced Linux Policy for the NetworkManager_dispatcher processes
DESCRIPTION¶
Security-Enhanced Linux secures the NetworkManager_dispatcher processes via flexible mandatory access control.
The NetworkManager_dispatcher processes execute with the NetworkManager_dispatcher_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep NetworkManager_dispatcher_t
ENTRYPOINTS¶
The NetworkManager_dispatcher_t SELinux type can be entered via the NetworkManager_dispatcher_exec_t file type.
The default entrypoint paths for the NetworkManager_dispatcher_t domain are the following:
/usr/lib/nm-dispatcher, /usr/libexec/nm-dispatcher
PROCESS TYPES¶
SELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux NetworkManager_dispatcher policy is very flexible allowing users to setup their NetworkManager_dispatcher processes in as secure a method as possible.
The following process types are defined for NetworkManager_dispatcher:
NetworkManager_dispatcher_t, NetworkManager_dispatcher_custom_t, NetworkManager_dispatcher_chronyc_t, NetworkManager_dispatcher_cloud_t, NetworkManager_dispatcher_console_t, NetworkManager_dispatcher_ddclient_t, NetworkManager_dispatcher_dhclient_t, NetworkManager_dispatcher_dnssec_t, NetworkManager_dispatcher_iscsid_t, NetworkManager_dispatcher_sendmail_t, NetworkManager_dispatcher_tlp_t, NetworkManager_dispatcher_winbind_t
Note: semanage permissive -a NetworkManager_dispatcher_t can be used to make the process type NetworkManager_dispatcher_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS¶
SELinux policy is customizable based on least access required. NetworkManager_dispatcher policy is extremely flexible and has several booleans that allow you to manipulate the policy and run NetworkManager_dispatcher with the tightest access possible.
If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.
setsebool -P daemons_dontaudit_scheduling 1
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
MANAGED FILES¶
The SELinux process type NetworkManager_dispatcher_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

FILE CONTEXTS¶
SELinux requires files to have an extended attribute to define the file type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files. SELinux NetworkManager_dispatcher policy is very flexible allowing users to setup their NetworkManager_dispatcher processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the NetworkManager_dispatcher, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t
NetworkManager_dispatcher_console_var_run_t
'/srv/NetworkManager_dispatcher/content(/.*)?'
restorecon -R -v /srv/myNetworkManager_dispatcher_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for NetworkManager_dispatcher:
NetworkManager_dispatcher_chronyc_script_t
- Set files with the NetworkManager_dispatcher_chronyc_script_t type, if you want to treat the files as NetworkManager dispatcher chronyc script data.
- Paths:
- /usr/lib/NetworkManager/dispatcher.d/20-chrony, /etc/NetworkManager/dispatcher.d/20-chrony-dhcp, /usr/lib/NetworkManager/dispatcher.d/20-chrony-dhcp, /etc/NetworkManager/dispatcher.d/20-chrony-onoffline, /usr/lib/NetworkManager/dispatcher.d/20-chrony-onoffline
NetworkManager_dispatcher_cloud_script_t
- Set files with the NetworkManager_dispatcher_cloud_script_t type, if you want to treat the files as NetworkManager dispatcher cloud script data.
- Paths:
- /etc/NetworkManager/dispatcher.d/hook-network-manager, /etc/NetworkManager/dispatcher.d/cloud-init-azure-hook, /usr/lib/NetworkManager/dispatcher.d/90-nm-cloud-setup.sh, /usr/lib/NetworkManager/dispatcher.d/no-wait.d/90-nm-cloud-setup.sh
NetworkManager_dispatcher_console_script_t
- Set files with the NetworkManager_dispatcher_console_script_t type, if you want to treat the files as NetworkManager dispatcher console script data.
NetworkManager_dispatcher_console_var_run_t
- Set files with the NetworkManager_dispatcher_console_var_run_t type, if you want to store the NetworkManager dispatcher console files under the /run or /var/run directory.
NetworkManager_dispatcher_ddclient_script_t
- Set files with the NetworkManager_dispatcher_ddclient_script_t type, if you want to treat the files as NetworkManager dispatcher ddclient script data.
NetworkManager_dispatcher_dhclient_script_t
- Set files with the NetworkManager_dispatcher_dhclient_script_t type, if you want to treat the files as NetworkManager dispatcher dhclient script data.
- Paths:
- /etc/NetworkManager/dispatcher.d/11-dhclient, /usr/lib/NetworkManager/dispatcher.d/11-dhclient
NetworkManager_dispatcher_dnssec_script_t
- Set files with the NetworkManager_dispatcher_dnssec_script_t type, if you want to treat the files as NetworkManager dispatcher dnssec script data.
NetworkManager_dispatcher_exec_t
- Set files with the NetworkManager_dispatcher_exec_t type, if you want to transition an executable to the NetworkManager_dispatcher_t domain.
- Paths:
- /usr/lib/nm-dispatcher, /usr/libexec/nm-dispatcher
NetworkManager_dispatcher_iscsid_script_t
- Set files with the NetworkManager_dispatcher_iscsid_script_t type, if you want to treat the files as NetworkManager dispatcher iscsid script data.
NetworkManager_dispatcher_script_t
- Set files with the NetworkManager_dispatcher_script_t type, if you want to treat the files as NetworkManager dispatcher script data.
- Paths:
- /etc/NetworkManager/dispatcher.d(/.*)?, /usr/lib/NetworkManager/dispatcher.d(/.*)?
NetworkManager_dispatcher_sendmail_script_t
- Set files with the NetworkManager_dispatcher_sendmail_script_t type, if you want to treat the files as NetworkManager dispatcher sendmail script data.
NetworkManager_dispatcher_tlp_script_t
- Set files with the NetworkManager_dispatcher_tlp_script_t type, if you want to treat the files as NetworkManager dispatcher tlp script data.
NetworkManager_dispatcher_winbind_script_t
- Set files with the NetworkManager_dispatcher_winbind_script_t type, if you want to treat the files as NetworkManager dispatcher winbind script data.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
COMMANDS¶
semanage fcontext can also be used to manipulate default file context mappings.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
