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.

 4 years ago
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.

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.

Pedro Alvarez 0ad0e9acac Make sure that RLC entity is only re-created if it switches modes. 4 years ago
Pedro Alvarez 0c20b7a455 Added support for S1AP modify bearer request support. This includes: 
- Handle received E-RAB S1AP at s1ap.cc.
 - Added methods to rrc.cc, rrc_ue.cc and rrc_bearer_cfg.cc to handle erab modify request.
 - Made RLC add_bearer() function capable of re-creating the RLC entity.
 - Send RRC reconfiguration to the UE and reply to the EPC with S1AP
   modify bearer response.

This commit also adds support to srsEPC to send S1AP modify bearer request for
testing purposes.

It's unclear why this isn't causing similar issues on B210 or X310,

Andre Puschmann 035d989737 pdu: fix unpacking of LCG2 of LBSR MAC CE 
LBSR packing is fine but this makes the eNB do wrong things
because it thinkgs LCG2 has no or too much data to send.

LCG2 is our default LCG for DRB1. One occasion we saw the issue
is doing full rate TCP DL which requires quite a bit of ACK traffic
back to the sender. With the BSR for LCG2 being wrong, providing
UL grants was delayed and so the TCP DL throuhgput was very low.

In the log below we see that the buff_size[2]=1 so there is data to send.
Interestingly, the packing was correct so Wireshark displays it correctly.
But the unpacking not, as can be seen in the MAC log below which reports
0 buffer state for all LCGs

22:08:54.804792 [MAC ] [I] [ 5084] pdu_get: sdu_len=1212, channel.sched_len=1213, bsr.buff_size[2]=1

stopping the pollRetx timer when receiving a status PDU
without checking the acknowledged PDUs is wrong.

if an ACK for another PDU, for which the polling bit has been set,
is still pending, it won't be rescheduled until another
PDU is transmitted that again starts the pollRetx timer.

* proc_bsr: fix LCG buffer state updating for TBSR

when sending a TBSR do not update the internal buffer
state of the BSR proc.

This caused issues because the buffer state for all LCG that
are not included in the TBSR are set to zero, although at least
one LCG does have data to transmit.
