[savannah-help-public] lwIP and getpeername() function

[Cristóvão Rufino]

Hello, everyone!

I'm using lwIP in a project together with CyaSSL DTLS (Datagram TLS - 
it's an UPD connection) capabilities. I'm having a problem/issue with 
the function 'getpeername()' of lwIP.

CyaSSL has a function that calls lwIP's getpeername() to retreive 
information about the peer connection (IP address and connection port). 
After some debugging, I noticed that after the call to 'getpeername()' 
the port is correctly returned but the IP address is read zero.

The problem/issue is that without this IP address I cannot finish the 
handshake necessary for CyaSSL to work correctly.

I need to know how I can fix this problem/issue ASAP (I'm in a tight 
schedule here...).

By the way: I'm using lwIP version 1.5.0-git-2012124 (because I need 
also IPv6 in this project. By the way, this DTLS connection is intended 
to run over IPv6 but I noticed that 'getaddrinfo()' does not work with 
IPv6 yet).
