Harald Welte c5097633d0 CSV: store file offset of SQN so we can update it efficiently later
This requires that the SQN field is large enough (8 decimal digits), in
order to do in-place changes to the field in the CSV.

osmo-auc - Core of an GSM/UMTS authentication Centre (AUC)

This program provides the core capability of an AUC, i.e. the
on-demand generation of authentication triplets / quintuples for
specific subscribers.

The approach taken here is very simple
 * use autentication routines of libosmocore/libosmogsm
 * load all subscriber key data into RAM
 * don't implement TCAP/MAP as external protocol
 * provide a simple API for generating triplets/quintuples for given IMSI

The idea is to grow this step by step into a more complete implementation:

 * add more storage backends than the CSV example, e.g. for various SQL
 * add code to actually write back the most recent subscriber SQN in case of UMTS
 * turn it into a multi-threaded implementation to scale on SMP
 * interface with Osmcoom SCCP/TCAP/MAP stack in Erlang
