Andre Puschmann 2ae35e4ce0 make sure status PDU doens't exceed grant size 6 years ago
Ismael Gomez 538f38cf54 Let PDCP Control PDUs be processed 6 years ago
Pedro Alvarez 9b6aaac1b5 Ignore PDCP status PDUs, instead of passing them to the GW. Check on the GW if the packet is large enough to hold an IPv4 header. 6 years ago

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.

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. 6 years ago
Francisco Paisana b936629221 removed rrc asn1 header from bcd_helpers, from rlc_interface, and rlc tests 6 years ago
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.

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
