      Code clean up part one. · 82ba5a35
      Melissa Elkadi authored
      This commit includes about 1/3 of the code clean up
      in preparation for the merge to the OAI develop
      branch. Several of the changes are white space changes,
      removing of logs, comment removals, and updating any
      changed code for our use-case to be clear for NSA mode.

      gnb sa: improve security · eeca3836
      Cedric Roux authored
      Note: some modifications have been done to the UE too, but for syntactic
      reasons. The UE may fail to work, not tested.
      
      For the UE, we have the problem of handling properly SecurityModeCommand.
      We don't verify its integrity. This is a bit complicated to handle properly
      and may require some API changes in the PDCP layer. So, as of today, the
      integrity of this message is not verified.
      
      Also, NSA mode has been touched, but it should not be a problem. But not
      tested, so not sure.

      IP ping traffic is working correctly · ca1805fa
      Melissa Elkadi authored
      In this commit we have updated the NRUE
      to properly get the RadioBearer info from
      the gNB. Because NSA and SA mode both use
      this information, we have updated the SA
      function previously in place by changing
      the name to allow both NSA and SA mode to
      use. This commit also updated the NR/LTE UEs
      configuration files to with the correct
      proxy IP address.

      Error checking for processing DL PDUs · 6ec545e2
      Melissa Elkadi authored
      Also, we only should be handling/generating AM
      PDUs in the PDCP/RLC layer, not UM PDUs. Updated
      the pre-configuration settings. This seemed to
      make the uplink traffic work (meaning it gets
      from NR UE to the gNB to the EPC). Woo! Still
      working on the downlink.

      Adding hexdumps to see dc/p bit in PDU · 4f1d5434
      Melissa Elkadi authored
      At this point we can see the UDP uplink data
      getting to the GTP layer of the gNB. This
      only works if you change the memcpy in serialize_sdu()
      to not have the encoded.byte

      Sending tunnel interface 'up' command to NR UE · 7f2e622b
      Melissa Elkadi authored
      Once the LTE UE's tunnel interface with the EPC
      is ready to be established, if we are in NSA mode,
      we do not want to launch the tunnel interface
      from the LTE UE side, but in the NR UE. Via itti_msgs
      we send the string containing the tunnel interface
      'up' command to the NR UE and bring it up from the NR UE.

      Enable IP TUN interface configuration upon reception of PDU Session... · f60e5997

      Enable IP TUN interface configuration upon reception of PDU Session Establishment Accept NAS message
      
      -User plane traffic validation with OAI UE and OAI CN:
      
      -Downlink ping initiated from the CN is received at the IP interface of the UE. However it seems that there is some packet corruption preventing the generaration of ping reply.
      
      -Uplink ping initiated from the UE reaches the OAI CN machine. However no ping reply is seen yet either.
