pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-sgsn/+/40984?usp=email ) Change subject: Store scu_iups in iu_rnc instead of ue_ctx ...................................................................... Store scu_iups in iu_rnc instead of ue_ctx All the ue_ctx belong to a given peer RNC, which holds the SCCP User to talk to it.
