struct udphdr data-structure - http://elixir.free-electrons.com/linux/latest/source/include/uapi/linux/udp.h#L22
sk_buff to udphdr APIs - http://elixir.free-electrons.com/linux/latest/source/include/linux/udp.h
Definitions for the UDP module - http://elixir.free-electrons.com/linux/latest/source/include/net/udp.h

And here is the copy paste of struct udp data-structure (/include/uapi/linux/udp.h) from the Kernel-source version 4.13 for quick reference:

struct udphdr {
	__be16	source;
	__be16	dest;
	__be16	len;
	__sum16	check;
};
