The flag lchan->activate.concluded prevents entering the lchan_on_fully_established()/lchan_on_activation_failure() more than once. So far it was checked by callers, instead place in the functions themselves. There is a potential functional change here, since during lchan_fail(), the concluded flag was set only after entering lchan_on_activation_failure(). Now it is already set at the start and prevents multiple re-entry beyond doubt. This patch is not a result of an actual observed faulty behavior, just from reading the code and seeing the slight loophole. Change-Id: I0c906438b05442d66255203eb816453b7193a6d8 |

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.
