Pedro Alvarez dd6d6f731d Passing SN provided by upper layers to PDCP entity. Using it to calculate TX_COUNT if passed. 2021-02-12 11:57:36 +00:00
Pedro Alvarez 492ea2a5a8 Addressing reviewers comments to #2290. 
Removing unecessary \n for logs and changed log of PDCP info queue
 capacity to debug to avoid log spam.

Pedro Alvarez fcaaf72187 Starting to add discard functionality to PDCP LTE entity. 
This includes:
  - Adding a queue (implemented with std::map) for undelivered PDUs.
    This queue uses the SN used for TX as the key.
  - Added discard timer that is started upon reception of the SDU. Upon
    expiry of the timeout a discard callback removes undelivered PDUs
from the queue.
  - Added the mechanisms to the notify_delivery to remove PDUs from the
    undelivered queue when the PDU is ACK'ed.
  - Added test case for both timer expiry and acknowledgment.
  - Fix up the getter for buffered SDUs to return the undelivered SDUs
  - Changed default PDCP discard timer, so AM has a discard timer by
    default.

Pedro Alvarez 7b25eac47c Fix race condition in rlc_am_stress test and other fixes related to this 
test. The race condition was being cause by write_sdu being called
simultanously to read_pdu, which could cause the read_pdu to try to get
the SDU info before it had been written by the write_sdu.

Changes in this commit include:
 - Make sure PDCP sn in included in RLC AM stress test.
 - Stop handling control PDU when TX is not enabled in RLC AM.
 - Fixed issue with length of the PDCP SN in rlc_stress_test.
 - Moved the place were sdu info erase was called to avoid double calls to erase
 - Tentative fix for race condition in rlc_am_stress test.
 - Added function to print information about undelivered_sdu_info_queue
   for debugging.

 2021-02-05 12:24:50 +00:00
Pedro Alvarez de90b4753f Added the ability of the RLC AM to notify the PDCP of the acknowledged 
PDCP PDUs. This includes:

- Modifying the byte_buffer_t to include PDCP SN meta-data. This way,
  the RLC can keep track of the ack'ed bytes for a specific PDCP PDU.
- Added in the RLC an `undelivered_sdu_info queue`, to keep track of the
  amount of ack'ed bytes and the total size of the PDCP PDU,
  so the RLC can know when delivery is finished.
- Added an interface between the PDCP and the RLC so that the RLC can
  notify the PDCP when it receives an ack from the status PDUs. The RLC
  passes to the PDCP a vector of all the ack'ed pdus in a rx'ed status PDU.
- Added some tests to the notify functionality. This includes some tests
  where the PDUs are acked imediatly, and one test where the PDU is
  retx'ed.

Andre Puschmann 8e13f04684 mac_pcap: refactor MAC PCAP and include NR RAT into same object 
after adding the thread-safe PCAP writer functionality to the EUTRA
MAC object it became clear that we don't wont to replicate the
same for the NR object.

This patch therefore refactors the class that now supports both EUTRA and
NR rats. The old mac_nr_pcap.[h/cc] has been deleted. All test-cases
and usages now use the new object that needs to pass the RAT type in
the ctor.

this patch addresses the last open point of #2160

Ismael Gomez c1c5fa426c Fix issue with new way of managing ul buffers not working with CA 2021-01-19 16:59:36 +01:00
Ismael Gomez 0780f3caea pdu_queue must be non-blocking in order to avoid the ue or enb to block in the event of a memory leak and the buffer pool running out of buffers. In that case, the null return shall be handled properly and error logged. This commit restores commit c4c44c33f4. 2021-01-16 15:22:29 +01:00

Andre Puschmann 78b07daf3b pcap: make public interfaces thread-safe and handle fopen returning nullptr 
the previous patch only introduced a thread-safe queue between
PHY workers (writers) and PCAP writer thread (consumer).

However, it is also required to protect the ctor (and close()) to
prevent corrupted PCAP files.

The patch also correctly handles the case where the PCAP couldn't
be openend for writing and doesn't start the thread.
