From 81635d3400f9837ecd6dcf3b512de50bf6aee9f2 Mon Sep 17 00:00:00 2001 From: Vadim Yanitskiy Date: Fri, 22 Mar 2019 02:09:06 +0700 Subject: libmsc: fix: properly initialize the SGs server It was observed that the SGs server is started before the actual VTY configuration is parsed. For example: sgs local-port 9999 local-ip 127.0.0.1 vlr-name vlr.example.net produces the following debug output: <0011> sgs_server.c:185 SGs socket bound to r=NULL<->l=0.0.0.0:29118 DLSS7 NOTICE <001e> osmo_ss7.c:1284 0: ASP Restart for server not implemented yet! DSGS NOTICE <0011> sgs_server.c:185 SGs socket bound to r=NULL<->l=0.0.0.0:9999 DSGS NOTICE <0011> sgs_server.c:185 SGs socket bound to r=NULL<->l=127.0.0.1:9999 DMNCC DEBUG <0004> msc_main.c:604 Using internal MNCC handler. The first startup is triggered by sgs_iface_init(), before reading the VTY configuration, so the logging style is different. The next two calls to sgs_server_open() are triggered during reading of the VTY configuration by cfg_sgs_local_port() and cfg_sgs_local_ip(). Let's avoid starting the SGs server three times, and do it once, after the VTY configuration is parsed. Also, keep the possibility to change the binding parameters at run-time.
