      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)

      bugfix: fix PDCP sequence management (plus some cleanup) · e3782b5c
      Cedric Roux authored
      With the introduction of X2AP into develop, the UEs now have to regularly
      send measurement reports.
      
      In the logs of the eNB, we see:
      
      [OSA]   Mismatch found in integrity for algorithm 2,
              got e0.a0.c2.66, expecting a5.9c.cb.57
      [PDCP]   [OSA][RB 1] eNB failed to validate MAC-I of incoming PDU
      
      This is a bug in the PDCP layer that uses wrong parameters to compute the
      integrity.
      
      This commit fixes this bug.
      
      The function pdcp_is_rx_seq_number_valid was removed. Its processing
      has been directly integrated into the function pdcp_data_ind.
      
      The function pdcp_mark_current_pdu_as_received is not called anymore.
      Its processing was not used later on, so as of today, not calling it does
      not introduce any functional change.
      
      The function pdcp_validate_security takes now as parameters both
      SN and HFN. Same for the function pdcp_get_next_count_rx.
      
      Useless constants PDCP_SN_5BIT, PDCP_SN_7BIT and PDCP_SN_12BIT have been
      removed.
      
      The compilation option ENABLE_SECURITY has been removed. It's now always
      on. (This may impact some use cases.)
      
      The PDCP for DRB using RLC AM is not correct. It was not correct before
      this commit (apart from the integrity bug). We should deal with a list
      of PDUs and transmit packets to upper layers as detailed in the specs.
      Today we transmit the PDU as soon as we get it. We don't care about
      duplicates, in-order delivery, timeouts.
      
      Also, we don't deal with "PDCP re-establishment". Not sure how that impacts
      the software.
      
      And, last but not least, there is still no ROHC.

      Perform S1 UE Context Release Complete after corresponding F1 message · d9d6ce37
      Robert Schmidt authored
      This commits isolates the S1 UE Ctxt Rel Complete and GTP Tunnel Delete
      Requests in functions and calls these function in the original place
      (rrc_rx_tx()). The same functions are then used in the F1 UE Ctxt Rel
      Complete handler to perform the same functionality, i.e. forward the UE
      Ctxt Rel Complete message to the MME and free outstanding resources (RRC
      context, GTP tunnels, S1 context).

      fix a lot of file mode · aea6b4b5
      Cedric Roux authored
      For whatever reason most of the files had their permission
      changed from 644 to 755, which is not wanted.
