2017-03-16UMTS AKA: implement SQN increment according to SEQ and INDNeels Hofmeyr1-4/+41
Add ind_bitlen column to auc_3g to record each USIM's IND size according to 3GPP TS 33.102 -- default is 5 bits, as suggested by the spec. Introduce auc_3g_ind to each connecting GSUP client to use as IND index for generating auth tuples sent to this client. With osmo_gsup_server_add_conn(), implement a scheme where clients receive fixed auc_3g_ind indexes based on the order in which they connect; each new connection takes the lowest unused auc_3g_ind, so in case one of the clients restarts, it will most likely receive the same auc_3g_ind, and if one client disconnects, no other clients' auc_3g_ind are affected. Add gsup_server_test.c to test the auc_3g_ind index distribution scheme.

Add commands to enable/disable Packet Service for a given IMSI. Changes are synced to DB and propagated at runtime to SGSN (in case of disable command). Change-Id: I23163ce8667292443ed61cb15c928357dba4b4be Related: OS#1645

2016-05-03Major update; Code now supports SAI, LU and ISD transactionsHarald Welte1-1/+62
We also introduce a 'gsup_router' which enables us to route a transaction to a given VLR. It works based on the SERIAL attribute communicated at time of the IPA multiplex setup as part of the CCM sub-protocol.

Once a remote IPA client is gone, we need to remove the associated osmo_gsup_conn object.
