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.

this addresses issue #254

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

Andre Puschmann 86e02921f0 fix regression in RLC base introduced during refactor causing eMBMS to fail 6 years ago
Andre Puschmann 22b4396c39 increase default tx_queue length for RLC UM and AM
- With the current default tx queue length (16 SDUs) the BSR reported by the UE
  is too low if the size of the SDU is relativly small (e.g. 100 B).
  This effectivly causes the eNB to only allocate a small grant
  to the UE and thus reduces the UL throughput for small SDUs.

Changes on srsENB mutexing logic to fix general race condition and deadlock issues (#229)
* fixed some issues with the UL scheduling

* Hack to fix UL scheduler

* minor fix

* Cleaned up code and fixed issue with the update_allocation function

* fixed the console printing in the enb

* log/console fix

* fixed the log print

* added a normalization factor

* RLC: entity uses dynamic instances. Simplified stop/reset/reestablish procedure. Added non-blocking interface

* Limit decimals in metrics stdout

* Changed mutexes to rwlock in RLC/RRC/MAC/PDCP to fix race conditions when removing users

* Fix deadlock bug for MIMO

* Remove headers

* Fix missing unlock causing overflows

* Do not decrease CQI when PUCCH (this is a temporal fix, requires to reduce the maximum MCS)

* Fix mutex unlock in worker

* Configurable RLC tx buffer. Default to 512 for enodeb

* Check NULL SDU in write_sdu()

* Protect RLC objects and tx_queue from being destroyed while using it

* Remove superfluous code

* Disable SIB logging

* Fix block_queue for enb

Andre Puschmann 7ca0988ea3 refactor RLC to use RAT-agnostic config 7 years ago
Andre Puschmann 8dbabb2834 rework bearer/LCID handling
This is a larger patch that reworks the LCID handling throughout the
code.

- It first moves the RB/LCID mapping out of common.h into the RRC object
  because different RATs may have different mappings.
- It adds a interface to RRC that other objects like RLC/PDCP/etc. may
  use to get the bearer name of a specific LCID.
- The patch also introduces a PDCP config class.
