[S] Change in osmo-mgw[master]: IuUP: allow Initialization from any address if not yet set

Attention is currently required from: neels. pespin has uploaded a new patch set (#2) to the change originally created by neels. ( https://gerrit.osmocom.org/c/osmo-mgw/+/35205?usp=email ) The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: IuUP: allow Initialization from any address if not yet set ...................................................................... IuUP: allow Initialization from any address if not yet set Do not refuse IuUP Initialization messages coming in on an RTP port if the remote IP address is not yet known. If an IUFP conn is not yet configured (pre-Initialization), allow rx from any remote address if the remote IP address is not yet known. If we refuse the IuUP Initialization, a 3G RNC may fail to set up a RAB. We will know the remote address only *after* assigning a RAB succeeded. So the IuUP Initialization must be allowed before knowing all addresses. At the time of writing, CRCX for IUFP are sent to osmo-mgw in either LOOPBACK or in RECVONLY mode: - current osmo-msc: recvonly - osmo-msc <= v1.10.0: loopback - osmo-hnbgw: loopback IuUP Initialization should work regardless of that. See also next patch I158dd046fdfcb10392cde3de8cc88dd095a05b40 IuUP is one layer below the loopback/send/recv decision for RTP; IuUP is always terminated at the MGW, while the AMR payload carries through.
