      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.

      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.

      Changed default DRB id from 3 to 1 · e7921f03
      gauthier authored
      With folowwing implicit rule
      drb id = x => correspondind lc id = x+2, eps bearer id = x+4
      
      Changed RLC inner structs, no more statically allocated array, now it is dynamic via malloc and collection of RLC entities are stored in a hashtable.
      Changed misc simple types
      Started compiling with all warning setted and treated as errors, still working on RLC and around...
      Add const qualifier wherever suitable (for example param frame, module id, const pointers, etc)
      
      Thinking about a type of context parameter in procedure calls in L2 data plane (modules id, frame, srb flag, enb flag, etc)...

      - Moved Makerules to OPENAIR_TARGETS · d5a12e3b
      Cedric Roux authored
      - Created Makefile.common that gathers common definitions for oaisim and lte-softmodem
      - Added ITTI capabilities to lte-softmodem (currently not stable)
      	* Created dummy l2l1 task
      	* Added -K option to output itti messages to file (some RT issues with file flush)
      - Added S1AP/SCTP tasks in lte-softmodem
      
      pre-ci ok
      lte-softmodem with HARD_RT=1 build ok
