2.6.32-longterm review patch. If anyone has any objections, please let me know. ------------------ From: Mathias Krause <minipli@xxxxxxxxxxxxxx> commit 3c0c5cfdcd4d69ffc4b9c0907cec99039f30a50a upstream. The ATM code fails to initialize the two padding bytes of struct sockaddr_atmpvc inserted for alignment. Add an explicit memset(0) before filling the structure to avoid the info leak.
