According to the upstream commit
df0bca049d01c0ee94afb7cd5dfd959541e6c8da "net: 4 bytes kernel memory
disclosure in SO_BSDCOMPAT gsopt try #2" in linux-2.6's git, there is
a missing initialisation of optval v.val that can be directly returned
to userspace when getsockopt() is called with SO_BSDCOMPAT optname
set.
