2016-02-13iso14443: verify the CRC of all messagesMartin Kaiser1-49/+85
define a function to dissect the CRC depending on the card type add a circuit for an activated card to keep track of the card type define a new circuit type CT_ISO1443 for this purpose, the circuit ID is always 0 as we support only a single active card Change-Id: I7250f834301612ba50743258ca7bdbe0199de3ea Reviewed-on: https://code.wireshark.org/review/13908 Reviewed-by: Martin Kaiser <wireshark@kaiser.cx>

2016-01-25Move the proto data stuff out of frame_data.[ch].Guy Harris1-1/+1
It's not tied to the frame_data structure any more, so it belongs by itself. Clean up some #includes while we're at it; in particular, frame_data.h doesn't use anything related to tvbuffs, so don't have it gratuitiously include tvbuff.h.

2015-11-12dissector for ISO14443 protocolsMartin Kaiser1-0/+593
This is a dissector for the ISO14443 protocols between a contactless smartcard and a card reader. The overall approach is similar to DVB-CI. We have a pseudo-header in front of the captured data that has information about the type of the captured data and the direction. For now, the dissector registers itself by name so it can be linked to a user-DLT. I am applying for an official DLT.
