Andre Puschmann f07a9277a0 fix RLC AM issue where an invalid status PDU was generated 
happens when very small grant is provided and the status
PDU generation fails because of a too small grant

add extra check to prevent that ACK_SN is also in NACKS list

Francisco Paisana 58e2e51044 removed rlc_interfaces. The rlc_cnfg types are now part of the rrc_interface_types. Removed implicit RB initialization in the RLC. 2019-07-05 10:44:15 +02:00
Andre Puschmann e8d6236975 remove init for all RLC TM/UM/AM 
- all RLC entities are now initialized during contruction
- there is no need to check for, e.g., existance of timers, during
  runtime
- there is also no need to call re-init during resume
- timers are freed in dtor

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

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
