Help enabling au_to_socket_ex for openbsm network events

[Rahul Gopi]

We are looking to enable creating of expanded socket type events in macos bsm. Saw support for au_to_socket_ex in source but not sure how to enable this for openbsm via audit_event, audit_control  et configuration files.  Greatly appreciate any help in this regard.

Platform MacOS , 10.14

from man audit.log

     The ``expanded socket'' token contains information about IPv4 and IPv6 sockets.  A
     ``expanded socket'' token can be created using au_to_socket_ex(3).

        Field                           Bytes              Description
        Token ID                        1 byte             Token ID
        Socket domain                   2 bytes            Socket domain
        Socket type                     2 bytes            Socket type
        Address type                    2 byte             Address type (IPv4/IPv6)
        Local port                      2 bytes            Local port
        Local IP address                4/16 bytes         Local IP address
        Remote port                     2 bytes            Remote port
        Remote IP address               4/16 bytes         Remote IP address

Thanks and regards
