Andre Puschmann 48537f3fe7 pdcp,rlc: increase number of PDCP SDUs for notification from RLC
the current value of 256 limits the number of PDCP SDUs that can be
notified from RLC. The limit is quickly hit when too many SDUs
are in flight. This can cause unwanted log entries and weird PDCP
behaviour.

the patch increases the value to 1024, which still can be too few if
many smaller SDUs are traveling.

The patch also set the log level to warning to quicker spot
misconfigs in logs.

Fixes #2616

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.

I used the circular_map container to avoid this sort of bugs

Andre Puschmann 0fdcea2924 rlc_am: count every segment retx as a full retx for this SN
previously we were only counting retx if we retx the start of a segment.
this could lead to unwanted behaviour, i.e., not counting retx
correctly and thus not triggering the maxretx attempt, if the receive
always sends NACKs with a SO_start.

The RLC spec is not clear on how this should be handled correctly but
IMHO using an integer number of retx is reasonable, even for segments
that might be retransmitted more often.

The alternative of using a fractional retx counter that may be increamented
proportional to the segment size that is retx is another alternative
but considered too complex to implement (and test correctly).

- 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

- 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 47654af717 pdcp_entity_lte: fix printf formatter for size_t
we've seen a heap-buffer overflow in fmt because printf wasn't using
the right formtter for size_t, which should be %zu

this patch fixes it for the PDCP LTE entity but we might have it elsewhere too

the patch refactor the logging when a new PDCP SDU is enqueued for
transmission at RLC.

If the SN is already present, only a warning is logged. From the RLC
perspective operation continues and the SDU will be transmitted.

The patch also changes the order of logs. When the SN cannot be inserted
inside the queue of undelivered SDUs, only one message is logged.

data type is a configurable but fixed-size vector.

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.
