Steffen Klassert 5ce93bd4cc xfrm: Validate address prefix lengths in the xfrm selector. 
[ Upstream commit 07bf7908950a8b14e81aa1807e3c667eab39287a ]

We don't validate the address prefix lengths in the xfrm
selector we got from userspace. This can lead to undefined
behaviour in the address matching functions if the prefix
is too big for the given address family. Fix this by checking
the prefixes and refuse SA/policy insertation when a prefix
is invalid.

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
