faluco 0465f6badd Implement a pool in FMT to avoid allocating heap memory when passing a char* to the backend, usually when formatting a %s argument. 
Previously since a char* can have any length, this was managed by FMT by converting it into a std::string.
Now we store it into a configurable size node that can store a fixed size string, otherwise it falls back to std::string.

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.

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.

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).

- 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 2cfc657fbb rlc_am_lte: refactor logging when PDCP SDUs are enqueued 
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.

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.

inspired by accepted (but not yet merged) PR to include the
(unique_)byte_buffer_t for MAC/PHY interfacing, this patch adds
a few more useful bits to that. Buffer management for UL data is now
done in MAC and only a pointer to the data is passed in the UL action.

* Move Tx softbuffer to MAC (until UL HARQ class is ready)
* Remove temparal data member in cc_worker
* Remove memcpy after packing MAC PDU

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
