Subject: atm: fix info leak via getsockname()
From: Mathias Krause <[email protected]>
[ Upstream commit 3c0c5cfdcd4d69ffc4b9c0907cec99039f30a50a ]
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.
