Andre Puschmann db9f093b63 add debug log when handling reordering timer 6 years ago
Andre Puschmann 849ad2655c fix creation of malformed RLC AM status PDU
the issue was caused by an unneeded length check during the
assembly of the status PDU. This length check caused an too early
break from the while-loop that adds all missing SNs to the status PDU
leaving the PDU struct in an invalid state where ack_sn was equal to
one of the NACK_SNs.
The fix is to simply remove the length check during the generation to
fully generate the status PDU. If, for whatever reason, MAC provides
a too small grant to fully fit the status PDU, the PDU will not be
generated, i.e. the calling function checks the return value and does
not pass the (then too big PDU) down the stack.

Andre Puschmann ecb6a0f99b fixing RLC AM bug where corrupted PDU causes segfault
the underlaying issue is that a corrupted PDU is passed to RLC
which claims to have segments whose total size exceed the size
of the entire PDU. Those PDUs are not ignored.

Andre Puschmann 58763fb714 stack: move initialization of log object into ctor
this fixes the issue when the stack is torn down if, for example,
the radio couldn't be loaded correctly. it will hence call stop() on all stack
components which are not initialzized yet, and logging therefore doesn't work.
the log object is know during contruction time and therefore can be passed
in as soon as possible.

- timers are freed in dtor

Andre Puschmann 955f5dd37a add mutex in pdcp entity
write_sdu and write_pdu are not re-entrant because all functions
that deal with the counters, e.g. integrity check and generate,
must be protected because MAC threads may call them at the same time.

Andre Puschmann c3441046c9 simplify RLC buffer status query procedures
- add a simple and low-overhead has_data() method to check whether
  an RLC entity has data to transmit or not
- use this method for all calls that are actually not interested
  in the amount of data to send
- use the more expensive get_buffer_state() for all cases where
  the actual size of the buffer is of importance
