Socket_inode and port_inode tables to map PIDs->ports via netlink inet_diag
Example query:
```
SELECT port.local_port,
       port.remote_port,
       port.local_ip,
       port.remote_ip,
       socket.pid,
       process.name,
       process.cmdline
       process.path
       FROM socket_inode AS socket
       JOIN port_inode AS port
       ON socket.inode = port.inode
       INNER JOIN processes AS process
       ON socket.pid = process.pid;
```
