Andre Puschmann 58ce9d3959 pdcp: adding basic test to check if control PDUs are handled correctly 
use a 3 B long status PDU to check if its dropped from the rx'ing entity
 4 years ago
Andre Puschmann 795db30338 pdcp: drop PDCP control PDUs 
this patch adds a check to drop all PDCP control PDUs
in order to prevent handling them as data PDUs.

This could happen when the size exceeded the arbitrary length check.

This should fix #1787

Bring back the circular array object. (#1712) 4 years ago
Andre Puschmann 6a56476b2a rlc: increase RLC Tx SDU queue 
the Tx SDU has been set to 128 PDUs because this gives approx.
150kByte UL buffer state (max value for Rel 8 BSR).

Previously, however, we've always reported too much pending UL
data because we weren't subtracting the transmitted data from
the reported data.

with this newer BSR reporting, however, even with full buffers we would
never report full buffers because the queues size is too short.

This seems to cause issues for iperf TCP sessions not resulting
in full DL rate, see isse #1703. It seems that the TCP bandwitdh
probing works better with larger buffers (in our case this can
only be achieved with more PDUs in the pool).

This should fix #1703

Andre Puschmann d48bc8837e pdu: refactor MAC PDU class 
this patch refactors the MAC PDU class, the main changes are:

* add to_string() method to pretty print PDU and subheaders
  This allows to have a single log entry per MAC PDU with all its
  contents.
  It removes the C-style fprint() method

* Simplity payload vs. w_payload_ce
  Before we've used payload when reading the PDU and w_payload_ce
  as a buffer when writing. In all getters we needed to differentiate
  between both. Now payload points to w_payload_ce initially and is
  only updated when parsing a new PDU.

* add various helpers, e.g. to get subheader index, update a BSR, ..

* fix PDU test to use new to_string() method

with the B210 and 2 RF ports, i.e. MIMO mode, we have stopped the

Either the issue doesn't exist in SISO mode or we never saw it but for MIMO
it can be reproduced easily with rate changes during streaming, i.e.:

Andre Puschmann 5e40bfe72c mac_pdu: unpack and print BSR index as well as BSR value in bytes 
before the BSR was extracted but the actual index (between 0 and 63)

for log parsing and debugging it is easier to follow the index
value. this patch therefore adds both values to the log message
and extends the API accordingly.

Note: According to the original UHD commit in

Andre Puschmann a7911f0dab pdcp,rlc: refactor SDU queueing policy 
this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer.
the previous design had issues when packets have been generated at a higher
rate above the PDCP than they could be consumed below the RLC.

When the RLC SDU queues were full, we allowed two policies, one to block on the write
and the other to drop the SDU. Both options are not ideal because they either
lead to a blocking stack thread or to lost PDCP PDUs.

To avoid this, this patch makes the following changes:

* PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full
  * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP
* remove blocking write from pdcp and rlc write_sdu() interface
  * all writes into queues need to be non-blocking
  * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC
* log warning if RLC still needs to drop SDUs
  * this case should be avoided with the monitoring mechanism

Andre Puschmann 035c369a43 mac_pdu: fix check of remaining length when adding new subheader to MAC PDU 
when adding a new subheader to a MAC PDU we should only add the subheader
if at least 2 bytes are left in the PDU. Even a 1 Byte MAC Control Element requires
another byte to pack the subheader.

This fixes #1424 in which a 3 B MAC opportunity is provided in the UL. After
adding the Short BSR, we tried to add another MAC subheader. Adding the subheader
succeeded even though no space is left to add a single byte. With this patch,
adding the subheader fails and the generates MAC PDU is correct.

Andre Puschmann f6d3467884 ringbuffer: fix timeout calculation for timed read 
with ZMQ RF, we've seen the radio returning -1 and traced
the issue down to the ringbuffer.
in fact, pthread_cond_timedwait() returned 22 (EINVAL) indicating
a wrong timeout value. The issue was likely an overflow
in the timespec parameter. This patch checks for the return
value of pthread_cond_timedwait() and also calculates the
nanosecond wrap around for the timespec

Andre Puschmann aed38a6028 rf_zmq: increase default ZMQ timeout to 2s 
amarisoft flags an RF error and exits after not receiving samples
for the radio. Running with ZMQ in the RFCI, the UE sometimes needs more
time to start up due to slow processing and no fftw wisdom file and
then Amarisoft eNB times out. This gives the whole process a little
bit more time. Should we still find it too short we may increase
it further.

Andre Puschmann 95f5093432 rlc_am: hold lock while handling new PDUs 
This lock was removed in 1cbf7eac because it was considered unneeded.
However, as can be seen in issue #1503, we need to protect the access
to rx_window, for example.

Issue #1503 shows a stack trace where a PHY worker generates a status PDU.
While holding the mutex to access rx_window, the stack thread on the
other hand, happily accesses the rx_window member without acquiring
the lock. This commit protects all handle_*() functions in write_pdu().

This reverts commit 1cbf7eac04.

Andre Puschmann 42bb387dae benchmark_radio: added option to change sampling rate during experiment 
this patch adds the -y paramter that changes the sampling rate
during a radio benchmark to stress-test the API

it turned out that some devices/drivers are very prone to
sampling rate changes. since this happens during UE operation
when the UE is searching for cells, we need to make sure
the driver/device supports that operation.
