card_emu: Clarify and differentiate F/Fi/F_index/Fi_index

The ISO7816 spec terms are well-defined, let's not abuse them. We used
to consider "Fi" as the "index into the table of F values", while the
spec actually considers Fi as the initial value for F.

Let's make sure we use the terms quite clearly:
* Fi and Di are the initial values for F and D
* F*_index and D*_index are the indexes into the ISO7816-3 Tables

Furthermore, let's track Fi separately from F, as e.g. the waiting
time definition only considers Fi as indicated in the ATR, despite
an actually different F value might have been negotiated via PTS
meanwhile.

SIMtrace v2.0

This is the repository for the next-generation SIMtrace devices, providing abilities to trace the communication between (U)SIM card and phone, remote (U)SIM card forward, (U)SIM man-in-the-middle, and more.

NOTE: Nothing in this repository applies to the SIMtrace v1.x hardware or its associated firmware. SIMtrace v1.x is based on a different CPU / microcontroller architecture and uses a completely different software stack and host software.

Supported Hardware

  • Osmocom SIMtrace 1.x with SAM3 controller ** this is open hardware and schematics / PCB design is published
  • sysmocom sysmoQMOD (with 4 Modems, 4 SIM slots and 2 SAM3) ** this is a proprietary device, publicly available from sysmocom
  • sysmocom OWHW (with 2 Modems and 1 SAM3 onboard) ** this is not publicly available hardware, but still supported

This Repository

This repository contains several directory

  • firmware - the firmware to run on the actual devices
  • hardware - some information related to the hardware
  • host - Programs to use on the USB host to interface with the hardware

The host software includes

  • libosmo-simtrace2 - a shared library to talk to devices running the simtrace2 firmware
  • simtrace2-list - list any USB-attached devices running simtrace2 firmware
  • simtrace2-sniff - interface the 'trace' firmware to obtain card protocol traces
  • simtrace2-cardem-pcsc - interface the 'cardem' fimrware to use a SIM in a PC/SC reader
