PS2:

I think this could have implications when we start to support things like SABP (Service Area Broadca […]

The point being, we don't use ue_context for active Iu connections. This is some completely optional HNBAP, it has no effect on any RUA conns at all. Actually I recently noticed, our ttcn3-hnbgw tests omit the HNBAP UE Register completely, they only do HNBAP HNB Register

On HNBAP UE Register, we store the allocated context id in a linked list. On HNBAP UE De-Register, we always ACK that, and also drop the id from the list without caring whether it exists. That is literally all that osmo-hnbgw does with the HNBAP UE Context.

So I guess we can apply this patch to completely drop ue_context in case that the ue_context leak situation continues to steal our time. Let's wait how the just merged patches turn out.
