Andre Puschmann 8024bf7820 mux_nr: improve logging when building UL MAC PDU 4 years ago
Andre Puschmann 9950278a12 nr,mac_sch_pdu,mux: fix packing of MAC subPDUs with 16bit L field
the created RLC PDU was too large to fit inside the MAC grant
because only the header room for the short L field was used.

The patch determines the correct size before passing the opportunity to RLC.

It also improves logging in error case by using the MAC logger instead of
stderr/stdout when error occurs.

Francisco dc763b5045 rlc am - fix bugs in buffered_pdcp_pdu_list
The count and container elements were not being correctly updated in the events
of SN overwrite, clear(), clear_pdcp_sdu(sn) of sn that doesnt exist
4 years ago
Francisco ebbb74e639 rlc am - use of circular_map container in RLC AM window
The window elements are not being correctly cleaned up when clear() is called
or when overwritten by newer SN. Furthermore, the window count member is not being
correctly updated when the insertion of a newer SN overwrites the previous one.

I used the circular_map container to avoid this sort of bugs

Francisco cdf72248f3 Reimplement batch-based background object/memory pool
Main changes:
- addition of pool utilities
- The node size/alignment and batch allocation threshold are now runtime arguments
- object pool and memory pool are not anymore based on the same class.
  The object pool cannot use intrusive free list because it would overwrite the object
  memory

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 ceacf8508d rlc_am_lte: fix handling of maxretx
this patch fixes the actions/handling after RLC detected
maxRetx reached for a given SN.

According to the TS, RLC should only inform upper layers and
not try to recover from the event itself.

As a consequence, we won't manipulate the Tx or Rx window.
As a result of this, we might retransmit a SN more than
the specified amount of times.

It's the task of RRC to reestablish the bearer to recover
from that.
