Recent fix "net: add length argument to
skb_copy_and_csum_datagram_iovec" added to some pre-3.19 stable
branches, namely

  stable-3.2.y: commit 127500d724f8
  stable-3.12.y: commit 3e1ac3aafbd0

Applied this fix to 3.12. Thanks!

You don't want this, you want Eric's fix (commit 197c949e7, "udp:
properly support MSG_PEEK with truncated buffers") although that's not
upstream yet.

It's now upstream as commit 197c949e7798fbf28cfadc69d9ca0c2abbf93191.
