Andre Puschmann fab86382c1 mac,rrc: add interface to set SR config explicitly without touching any other MAC function 
when releasing PUCCH/SRS (see 5.3.13 in 36.331) we need to reset the SR config as well.
In our case, SR is handled by MAC so we need to (re-)configure MAC, not all of
MAC though, just SR.

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

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.

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 9307a54512 pdcp: adding enable_security_timed() method 
this is an extension to the currently available security
configuration and activation methods provided by PDCP.
The new call allows to specify a Rx and Tx SN after which the
entire security config, i.e. integrity and ciphering, should
be enabled.

this is mainly required for the PDCP entity of the conformance
testing SS but could potentially also be used by the eNB
to enable security for PDCP after sending the SecModeCommand
for example.

the extra call was added to not break the existing API.

therefore, send a SIGKILL to our process and make sure we don't leave any

Andre Puschmann 9e113f8b27 pdcp: allow to configure security for rx/tx seperately 
previously PDCP security (integrity and ciphering) could only
be enabled for both Rx and Tx at the same time.

this, however, caused an issue during the conformance testing in which,
in TC_8_2_1_1() for example, the eNB sends a SecModeCommand and a
RRC Reconfiguration in the same MAC TB. In this case, the eNB
needs to be able to enable DL security right after sending the SecModeCmd
in order to send the RRCReconfig encrypted. However, enabling UL security needs
to be postponed until after the SecModeComplete is received.

This patch allows to enable PDCP security for rx/tx independently if
that is needed. The default way is like before, enabling it for tx/rx at
the same time.

Andre Puschmann c7343cf6d8 protect sf_buffer from overrun in receive_samples 
this patch adds a buffer len paramter to the receive_samples() call
that protects the (also) provided buffer from overflowing.

currently each call to srslte_ue_sync_zerocopy() which then calls receive_samples()
relies on a buffer that is "big enough". But that buffer is sometimes
2 subframes, sometimes 3 or 5, sometimes has space for the maximum PRB size, sometimes
only for 6 PRBs (i.e. during cell search).

By extending the interface to pass the buffer size we can make sure that
only samples are received that actually fit inside the provided buffer.

Harald Welte 2e426948fe [ENB] Add CFSB support 
This commit introduces CSFB (circuit switched fall-back) capabilities to
srsLTE.  Actually, all the eNB has to do is to send a
RrcConnectionRelease with the RedirectedCarrierInfo IE.

The MME triggers this by the S1AP CS Fallback Indicator IE, which may
be present either in the Initial Context Setup Requst or in the
UE Context Modification Request.

As srsLTE has no support for the UE Context Modification Request at all
yet (!), basic support for this message is introduced in this patch.

Both Mobile Originated and Mobile Terminated CSFB with a coupel of
different UE models have been verified using this patch in a setup
consisting of srsENB attached to an undisclosed EPC connected via SGsAP
to a complete  Osmocom 2G network.

Pedro Alvarez ca603810ce Adding Downlink data notification and paging functionality to the EPC. 
This entails:

  * Adding S1AP paging messaging to the MME.
  * Adding the Downlink Data Notification, Donlink Data Notification Acknoledgment, and Downlink Data Notification Failure Messages.
  * Adding the logic at the GTP-U to detect that Downlink Data notification needs to be sent.
  * Proper handling of the new GTP-C messages at the MME GTPC and SPGW GTPC classes
  * Add queuing mechanisms at the GTP-U while waiting for paging response. Queue is flushed when paging fails (timeout or other).
  * Make sure eNB's SCTP information is properly stored.
  * Make sure UE's GUTI information is properly stored.

make EIA and EEA algorithms configurable (#323) 
this patch allows to configure the EIA and EEA algorithms
the UE uses and announces during attach. They can
be specified as a comma-separated list.

The patch also removes a dedicated NAS config class and uses
the default nas_args_t type for this. There was a full
duplication of members before.

The patch also converts nas_args_t and usim_args_t into a class
with a default constructor that initialize all booleans.

Andre Puschmann 22b4396c39 increase default tx_queue length for RLC UM and AM 
- With the current default tx queue length (16 SDUs) the BSR reported by the UE

  This effectivly causes the eNB to only allocate a small grant
  to the UE and thus reduces the UL throughput for small SDUs.
