      Handle faulty MeasurementReport gracefully · 30054b80
      Robert Schmidt authored
      A UE might send a MeasurementReport without the actual IEs present
      (intentionally or not). Check this and handle appropriately to avoid
      assertion
      
          Assertion (measurementReport->criticalExtensions.present == NR_MeasurementReport__criticalExtensions_PR_measurementReport && measurementReport->criticalExtensions.choice.measurementReport != ((void*)0)) failed!

      Handle repeated NGAP Initial Context Setup Request · d71104da
      Robert Schmidt authored
      Prior to this commit, if we receive an Initial Context Setup Request for
      a UE that has AS security set up, the gNB asserts with
      
          Assertion (!ue_p->as_security_active) failed!
          In rrc_gNB_generate_SecurityModeCommand() openairinterface5g/openair2/RRC/NR/rrc_gNB.c:2590
          logic error: security already activ
      
      However, TS 38.413 says:
      
      > The AMF may initiate the Initial Context Setup procedure if a
      > UE-associated logical NG-connection exists for the UE
      
      (I interpret this as "it might happen anytime")
      
      > store the received Security Key in the UE context and, if the NG-RAN
      > node is required to activate security for the UE, take this security key
      > into use.
      
      (I interpret this as "do not set up AS security again")
      
      In this commit, handle if we receive an Initial Context Setup Request
      for an existing UE context. As said in the spec, we store the keys. If
      security is not active, we trigger RRC Security Mode Command. If it is
      active, we skip Security, and directly set up a PDU session. If there is
      also no PDU session, we simply forward the NAS message, and acknowledge.
      
      If there was no AS security, after security, the gNB would trigger the
      setup of PDU sessions (if any), and then forward any NAS PDUs, which is
      stated in the if block if AS security is already active.
