      nr: improve x2/rrc for ENDC · 4236ff2b
      Cedric Roux authored
      This commit introduces several enhancements in X2AP and RRC to deal
      with ENDC. The main goal is to deal with UE's on/off and with various
      errors.
      
      The following work is included:
      
          - DC prep and DC overall X2 timers
          - X2 messages for UE release and DC timers' timeout
      
      Open problems:
      
          - what to do when the UE sends an scg Failure? This commit removes
            the UE. And this removal may not be correctly done
          - UE removal in the gNB's PHY layer (a next commit is coming,
            but it is hackish and will need a rework)

      trigger NR activation based on RRC measurements · 51ab31a3
      Cedric Roux authored
      An NR-capable UE will transmit some NR measurements.
      Once received, the whole process on nr-cell addition is started.
      It will fail quickly.
      
      Many things are still missing.
      
      What is not handled properly with this commit:
      - in x2ap_eNB_handle_sgNB_add_req we hardcode the gNB ID
      - nr triggering is done if we receive a measurement but this measurement is
        not analyzed at all
      - no timers (T_dc_overall, T_dc_prep) and as is the code fails and then the
        next triggering after UE reconnection will not work (x2 ID are not well
        handled here and there in the code)
      
      Note also that the gNB part has not been looked at all for this commit.
      
      This is work in progress...

      x2ap/sctp: increase buffer size · 2421b71d
      Cedric Roux authored
      The 5G phone OPPO has a very big UE capability (> 2KB).
      
      We need bigger buffers to transfer this, especially in x2 handover.
      
      Also the sctp messages need a bigger buffer.
      
      Note: in sctp, we didn't check for partial messages, it's now
            done. When detected, we exit. To be redone differently
            if needed. (Look for "if (!(flags & MSG_EOR))".)
