There was always a 1:1 correspondence between gsm_subscriber_connection and osmo_bsc_sccp_con, so there's really no point in having two separate dynamically allocated data structures with pointers back and forth and another linked list around. Let's merge osmo_bsc_sccp_con into gsm_subscriber_connection for simplicity. The resulting code might not be elegant in places, but I've tried to do only the most simple changes in this patch, while further simplifications can be done in later subsequent patches. As a side-effect, this patch also fixes lchan clearing if the MSC (or the local SCCP provider) hard-disconnects the SCCP connection. Change-Id: Idd2b733477ee90d24dec369755a00f1c39c93f39 |

About OsmoBSC ============= OsmoBSC originated from the OpenBSC project, which started as a minimalistic all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached maturity and diversity (including M3UA SIGTRAN and 3G support in the form of IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one approach to fully independent separate programs as in typical GSM networks. OsmoBSC was one of the parts split off from the old openbsc.git. Before, it worked as a standalone osmo-bsc binary as well as a combination of libbsc and libmsc, i.e. the old OsmoNITB. Since the standalone OsmoMSC with a true A interface (and IuCS for 3G support) is available, OsmoBSC exists only as a separate standalone entity. OsmoBSC exposes - A over IP towards an MSC (e.g. OsmoMSC); - Abis interfaces towards various kinds of BTS; - The Osmocom typical telnet VTY and CTRL interfaces.
