2017-08-30Implement AoIP, port to M3UA SIGTRAN (large addition and refactoring)Philipp Maier1-5/+76
This was originally a long series of commits converging to the final result seen in this patch. It does not make much sense to review the smaller steps' trial and error, we need to review this entire change as a whole. Implement AoIP in osmo-msc and osmo-bsc. Change over to the new libosmo-sigtran API with support for proper SCCP/M3UA/SCTP stacking, as mandated by 3GPP specifications for the IuCS and IuPS interfaces. From here on, a separate osmo-stp process is required for SCCP routing between OsmoBSC / OsmoHNBGW <-> OsmoMSC / OsmoSGSN jenkins.sh: build from libosmo-sccp and osmo-iuh master branches now for new M3UA SIGTRAN.

2017-08-27Treat SIGTERM just like SIGINT in our programsHarald Welte1-0/+2
When somebody kills the process, it's best to handle the signal and to use the opportunity for some cleanup. We always did this in the NITB on SIGINT, but never on SIGTERM. Let's change it. Change-Id: Iea6804325a6575ceab5edfd28dd20249462f143b
2017-08-27NITB: remove 'help' output about '-a' option that is removed for agesHarald Welte1-2/+0
This option was present in very early versions of the NITB, but at least since 2011 it is no longer supported. It's still listed in --help output, which is wrong. Change-Id: I1d2cceb588ec5fb34ec5e2c05a7d8c93310bee88
2017-08-27Implement IuCS (large refactoring and addition)Neels Hofmeyr2-0/+571
osmo-nitb becomes osmo-msc add DIUCS debug log constant add iucs.[hc] add msc vty, remove nitb vty add libiudummy, to avoid linking Iu deps in tests Use new msc_tx_dtap() instead of gsm0808_submit_dtap() libmgcp: add mgcpgw client API bridge calls via mgcpgw Enable MSC specific CTRL commands, bsc_base_ctrl_cmds_install() still needs to be split up.
