faluco 54fab314c0 Enhance RRC eNB events:
- Implement a common event "log_rrc" for all RRC events and discriminate by procedure using an enum.
- Log events for connection, reestablishment, reconfig, reject and release.
- Log the corresponding ASN1 message used by each procedure.
- Redefine the JSON object for this event to match the new structure.

Fixed a compilation error detected by the static analyzer in gcc9.3 where bounded_vector::data() was using taking the address of the internal buffer which confused it, prefer to use the data method of std::array.

Andre Puschmann 20cbc48f90 rlc_am_lte: refactor PDCP/RLC interface to use fix sized data structure
this patch replaces the std::vector type used in the interface between
PDCP and RLC to signal delivery status between both layers. The new
data type is a configurable but fixed-size vector.
The RLC AM doesn't need to dynamically allocate the vector for every SN but
uses the tx_window for storage.

Andre Puschmann 46d8ed8742 enb,rrc: delay UE release after RLC maxRetx
this fixes the eNB behaviour when RLC signals maxRetx reached.
By directly releasing the UE, we ignore the fact that the UE
could still have the reestablishment counters running, so
could attempt a reestablishment, which would result in a reject
because we would have destroyed the UE context too early.

this patch delays the removal of the UE to wait at least
until the reestablishment timers are expired.

RLC failure to deliver notifications and discard timer limits to 1500ms (#2368)
* Added interfaces for the RLC to notify the PDCP of failure to transmit
SDU

* Limit discard timer to 1500ms, to avoid issues of lingering SDUs in the undeliverd_sdus_queue.

* Fix bug in early exit of notify_delivery and notify_failure

* fix compilation issue in rlc-pdcp notification

Francisco 3265d940ec remove byte buffer pool cached member variables as they are unnecessary now. 4 years ago
Pedro Alvarez de90b4753f Added the ability of the RLC AM to notify the PDCP of the acknowledged
PDCP PDUs. This includes:

- Modifying the byte_buffer_t to include PDCP SN meta-data. This way,
  the RLC can keep track of the ack'ed bytes for a specific PDCP PDU.
- Added in the RLC an `undelivered_sdu_info queue`, to keep track of the
  amount of ack'ed bytes and the total size of the PDCP PDU,
  so the RLC can know when delivery is finished.
- Added an interface between the PDCP and the RLC so that the RLC can
  notify the PDCP when it receives an ack from the status PDUs. The RLC
  passes to the PDCP a vector of all the ack'ed pdus in a rx'ed status PDU.
- Added some tests to the notify functionality. This includes some tests
  where the PDUs are acked imediatly, and one test where the PDU is
  retx'ed.
