Detailed Description

Author: Henrik Kramshoej hlk@k.nosp@m.rams.nosp@m.e.org

VXLAN tunneling scheme decoder.

This implementation is based on the following specification doc: https://tools.ietf.org/html/rfc7348

Function Documentation

◆ DecodeVXLAN()

int DecodeVXLAN	(	ThreadVars *	tv,
		DecodeThreadVars *	dtv,
		Packet *	p,
		const uint8_t *	pkt,
		uint32_t	len
	)

Parameters

pkt	payload data directly above UDP header
len	length in bytes of pkt

Note: p->flow is not set yet at this point, so we cannot easily check if the flow is unidirectional here.
