> ## Summary > add protection in the case when conn's domain isn't match with addr's family. When you create a IPv4 socket and connect to an IPv6 address, the original code logic will use the input IPv6 address as a IPv4 address only because the socket's domain is created in AF_INET! This patch is to avoid this case, in which it refuses the connection and return EPROTOTYPE（error protocol type） > > ## Impact > When you use nuttx's socket in a wrong way, it will refuse this wrong operation > > ## Testing > Testing cases has been done with nuttx sim program for example ping [www.baidu.com（UDP](http://www.baidu.com%EF%BC%88UDP) packet, DNS pkts） wget [http://www.baidu.com（TCP](http://www.baidu.com%EF%BC%88TCP) packet, HTTP pkts） -- This is an automated message from the Apache Git Service.
