fixeria has uploaded this change for review. ( https://gerrit.osmocom.org/c/erlang/osmo-s1gw/+/41490?usp=email ) Change subject: s1ap_proxy: correct handling of UE CONTEXT RELEASE REQUEST ...................................................................... s1ap_proxy: correct handling of UE CONTEXT RELEASE REQUEST By sending a UE CONTEXT RELEASE REQUEST, the eNB is requesting the MME to terminate the UE context. This procedure itself does not terminate the UE context nor the associated E-RABs. Therefore, the S1GW should not terminate E-RAB FSMs upon receiving this PDU. Keep the function clause in s1ap_proxy, so that the respective ?S1GW_CTR_S1AP_PROXY_IN_PKT_RELEASE_CTX_REQ is properly updated. Correct the unit test: E-RAB is now expected to remain alive.

[M] Change in ...osmo-s1gw[master]: s1ap_proxy_test: add TCs simulating late E-RAB SETUP Rsp

Add a unit tests for this scenario, preparing for a follow-up patch making the E-RAB FSM more flexible. The PDUs triggering late E-RAB SETUP Rsp event are currently being dropped because they reference no longer existing E-RABs.
