From 2e5e94c3283fa4f5160962f42e7cd5d4e39b7d1e Mon Sep 17 00:00:00 2001 From: Jacob Erlbeck Date: Mon, 8 Dec 2014 15:26:47 +0100 Subject: sgsn: Support subscriber based authentication This commit mainly extends sgsn_auth.c to use and support the auth_state SGSN_AUTH_AUTHENTICATE. It will be activated when IMSI and IMEI are available, authentication is required (subscr->sgsn_data->authenticate is set), but the MM context is not marked as authenticated. If the state has been set to SGSN_AUTH_AUTHENTICATE and sgsn_auth_update() is called, the GMM layer will be informed by invoking gsm0408_gprs_authenticate().
