commit e0169171146427b06d6c20759a6f3046cfb11f70 Author: Jacob Erlbeck jerlbeck@sysmocom.de Date: Fri Nov 28 14:55:25 2014 +0100

sgsn: Work on 2 phase authorization (WIP)

This implements the MAP way of subscriber validation when the MS tries an Attach Request: 1. perform authentication (optionally invoke the sendAuthInfo procedure), starts the AuthAndCiph procedure 2. perform update location 3. insert subscriber data 4. finish the update location 5. Attach Accept / Attach Reject

This is currently accessible via the VTY interface.

TODO: - Apply this to (periodic) RA Update Req - Delete Subscriber Data - Improve on procedure collisions (repeated Attach Req is sometimes not handled properly) - PDP info - Commit cleanup
