Description:
Upon accepting a client connection, the proxy fails to resolve the client hostname, because the struct sockaddr reference is invalid.

2008-11-07 12:39:08: (debug) network-socket.c.731: ignoring invalid sa_family 24576
2008-11-07 12:39:08: (message) network-mysqld.c.1459: resolving address failed, closing connection

How to repeat:
Start the proxy or agent and connect with a mysql client.

The sockaddr_in will not be filled by accept() even though the connecting is correctly accepted and the socket is connected, causing later code to fail.

Suggested fix:
unknown.

fix pushed.

On IA64 the types int and socklen_t have different sizes (int's are 32bits, socklen_t == long == 64bit), causing accept() to be unable to populate the sockaddr of the accepted socket.

- testing Hudson build 3213 QUAN works with and without SSL
- now waiting for the next installer to finally close this bug ...

2.0.0.7094 fails, it looks that the fix didn't go into this build

OK in 2.0.0.7095
