net/appletalk: Fix kernel memory disclosure
[ Upstream commit ce7e40c432ba84da104438f6799d460a4cad41bc ]
ipddp_route structs contain alignment padding so kernel heap memory
is leaked when they are copied to user space in
ipddp_ioctl(SIOCFINDIPDDPRT). Change kmalloc() to kzalloc() to clear
that memory.
