3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mathias Krause <mini...@googlemail.com>
[ Upstream commit e862f1a9b7df4e8196ebec45ac62295138aa3fc2 ]
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.
