Title: RECV/RECVFROM RETURN VALUE
Description: If the peer performs an orderly shutdown, then recvfrom currently returns
an error with errno set to ENOTCONN. This is wrong. There is a fine
distinction. The ENOTCONN errno is intended for the case where the socket
was never connected. In the case were the socket was connected then the
peer performs an order shutdown: "...If no messages are available to be
received and the peer has performed an orderly shutdown, recv() shall
return 0. ..."
Status: Open and there is a kludge in apps/netutils/ftpd/ftpdc.c work around this
bad return value.
Priority: Medium
