[L] Change in osmo-ttcn3-hacks[master]: mme: Initial working state for MME_Tests_SGsAP.ttcn tests

by pespin

pespin has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/41046?usp=email ) Change subject: mme: Initial working state for MME_Tests_SGsAP.ttcn tests ...................................................................... mme: Initial working state for MME_Tests_SGsAP.ttcn tests MME_Tests_SGsAP.ttcn tests were introduced to the repository many years ago (~2019), but they were mostly WIP and were never run as part of the regular testsuite. This commit reworks and extends previous work to get them up to date with current MME_Tests and makes most of them passing. TC_sgsap_alert_* tests are still in WIP and will be fixed in follow-up work.

[M] Change in osmo-ttcn3-hacks[master]: SGsAP_Emulation: Introduce proper support for server-mode

by pespin

pespin has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/41083?usp=email ) Change subject: SGsAP_Emulation: Introduce proper support for server-mode ...................................................................... SGsAP_Emulation: Introduce proper support for server-mode Prior to this commit, only initial (not really useful) SCTP server-mode support existed in SGsAP_Emulation. This is basically because MSC_Tests uses the SCTP client-mode, and MME_Tests_SGsAP were not yet in a fully working state. In server-mode, we have a conn_id for the listening socket and a conn_id for the accepted socket; track them properly. Moreover, in server node we definetly need some sort of event to wait for the client to connect; introduce it. Based on existing work in Iuh_Emulation.
