Andre Puschmann 58ce9d3959 pdcp: adding basic test to check if control PDUs are handled correctly 
use a 3 B long status PDU to check if its dropped from the rx'ing entity
 4 years ago
faluco f0d651ae8e - Fixed a leak in the MME class not releasing the static byte buffer pool. 
- Now the pool gets destroyed on program exit using a unique_ptr.
- Removed manual cleanup() calls in all the code base to free the pool instance.

Andre Puschmann d48bc8837e pdu: refactor MAC PDU class 
this patch refactors the MAC PDU class, the main changes are:

* add to_string() method to pretty print PDU and subheaders
  This allows to have a single log entry per MAC PDU with all its
  contents.
  It removes the C-style fprint() method

* Simplity payload vs. w_payload_ce
  Before we've used payload when reading the PDU and w_payload_ce
  as a buffer when writing. In all getters we needed to differentiate
  between both. Now payload points to w_payload_ce initially and is
  only updated when parsing a new PDU.

* add various helpers, e.g. to get subheader index, update a BSR, ..

* fix PDU test to use new to_string() method

Andre Puschmann a7911f0dab pdcp,rlc: refactor SDU queueing policy 
this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer.
the previous design had issues when packets have been generated at a higher
rate above the PDCP than they could be consumed below the RLC.

When the RLC SDU queues were full, we allowed two policies, one to block on the write
and the other to drop the SDU. Both options are not ideal because they either
lead to a blocking stack thread or to lost PDCP PDUs.

To avoid this, this patch makes the following changes:

* PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full
  * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP
* remove blocking write from pdcp and rlc write_sdu() interface
  * all writes into queues need to be non-blocking
  * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC
* log warning if RLC still needs to drop SDUs
  * this case should be avoided with the monitoring mechanism

Andre Puschmann a3d7d4517c rlc_um: add dedicated unit test for the PDU packing bug 
Here is the test output with the fix disabled:

13:47:42.679774 [RLC_UM_1] [D] MAC opportunity - 14 bytes
13:47:42.679784 [RLC_UM_1] [D] pdu_space=14, head_len=2
13:47:42.679790 [RLC_UM_1] [D]  adding new SDU segment - 10 bytes of 10 remaining
13:47:42.679834 [RLC_UM_1] [D]  Complete SDU scheduled for tx. Stack latency: 0 us
13:47:42.679909 [RLC_UM_1] [D] pdu_space=4, head_len=2
13:47:42.679922 [RLC_UM_1] [D]  adding new SDU segment - 0 bytes of 10 remaining
13:47:42.679928 [RLC_UM_1] [I]  Tx PDU SN=0 (14 B)
13:47:42.679974 [RLC_UM_1] [D]  vt_us = 1

The test checks the correct packing and of the two PDUs at the end.
