      x2ap: timers, cleanup · 9456fe58
      Cedric Roux authored
      This commit introduces X2AP timers (t_reloc_prep, tx2_reloc_overall).
      You need to set the values in the configuration file.
      X2AP can be enabled or disabled in the configuration file too (disabled
      by default).
      Some deadcode was removed.

      Correctly link lte-uesoftmodem(-nos1) (hack) · bbedd315
      Robert Schmidt authored
      Although not used in the UE, we currently need to link the F1 library into it.
      This is because we do not define ASN_DISABLE_OER_SUPPORT (otherwise, F1 has
      compilation problems). In this case, some functions are apparently not
      correctly defined, giving linker errors in the UE. Linking F1 in solves the
      This is a hack. It would be better to be able to define ASN_DISABLE_OER_SUPPORT
      and have no compilation errors or compile everything with
      ASN_DISABLE_OER_SUPPORT except F1. I did not do this because I did not find
      another way than add target_compile_definitions() to every target except F1
      which adds many lines just so that one target (F1 ASN.1) compiles correctly (in
      other words, F1 needs to be fixed).

      x2: first implementation of ID management, some cleanup · c394188e
      Cedric Roux authored
      Some deadcode was removed.
      The implementation of the ID management is not finished.
      It will only work if the handover is successful. No error
      recovery has been done. For error recovery, we need to
      implement the X2AP timers. As it is, in case of error, an ID
      might very well never be released.
      It has been tested with 1 and 2 UEs doing handover more or less
      at the same time.

      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
      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
      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

      For whatever reason most of the files had their permission
      changed from 644 to 755, which is not wanted.
