NetworkManager_dispatcher_dhclient_selinux

Security-Enhanced Linux secures the NetworkManager_dispatcher_dhclient processes via flexible mandatory access control.

The NetworkManager_dispatcher_dhclient processes execute with the NetworkManager_dispatcher_dhclient_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_dhclient_t

The NetworkManager_dispatcher_dhclient_t SELinux type can be entered via the NetworkManager_dispatcher_dhclient_script_t file type.

The default entrypoint paths for the NetworkManager_dispatcher_dhclient_t domain are the following:

/etc/NetworkManager/dispatcher.d/11-dhclient, /usr/lib/NetworkManager/dispatcher.d/11-dhclient

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 psbP

Policy governs the access confined processes have to files. SELinux NetworkManager_dispatcher_dhclient policy is very flexible allowing users to setup their NetworkManager_dispatcher_dhclient processes in as secure a method as possible.

The following process types are defined for NetworkManager_dispatcher_dhclient:

NetworkManager_dispatcher_dhclient_t

Note: semanage permissive -a NetworkManager_dispatcher_dhclient_t can be used to make the process type NetworkManager_dispatcher_dhclient_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

SELinux policy is customizable based on least access required.  NetworkManager_dispatcher_dhclient policy is extremely flexible and has several booleans that allow you to manipulate the policy and run NetworkManager_dispatcher_dhclient with the tightest access possible.

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

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 lsbP

Policy governs the access confined processes have to these files. SELinux NetworkManager_dispatcher_dhclient policy is very flexible allowing users to setup their NetworkManager_dispatcher_dhclient processes in as secure a method as possible.

STANDARD FILE CONTEXT

SELinux defines the file context types for the NetworkManager_dispatcher_dhclient, 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_dhclient_script_t '/srv/NetworkManager_dispatcher_dhclient/content(/.*)?'
restorecon -R -v /srv/myNetworkManager_dispatcher_dhclient_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for NetworkManager_dispatcher_dhclient:

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

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.

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.
