3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mathias Krause <mini...@googlemail.com>
[ 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.
