Add missing conn->assignment.created_ci_for_msc to gscon_forget_mgw_endpoint_ci(). Before this patch, when assignment.created_ci_for_msc lingers after a DLCX, it can cause a use-after-free on assignment_reset(). Possible scenario is rx BSSMAP Clear Cmd during ongoing Assignment. In assignment_reset(), locally cache the ci pointer, because gscon_forget_mgw_endpoint_ci() now NULLs created_ci_for_msc. Related: OS#5572 Change-Id: If89610020f47fd6517081dd11b83911b043bd0f1 |

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. Find OsmoBSC issue tracker and wiki online at https://osmocom.org/projects/osmobsc https://osmocom.org/projects/osmobsc/wiki OsmoBSC-NAT is a specialized solution to navigating RTP streams through a NAT.
