Add feature to provide custom GTP-U (S1) address to be advertised inside S1AP messages
...
This feature is useful in scenarios where eNB is behind a NAT and EPC on public cloud
Since eNB's GTP-U can only bind to IP address visible in it's host (usually a private IP beind a NAT), it advertises the same to UE in S1AP message
resulting in traffic from EPC to eNB (DL traffic) not able to reach eNB. This commit solves this issue by providing a means to advertise a different IP address than the one GTP-U UDP socket is bound to.
This IP is usually advertised in InitialContextSetupResponse and E-RABSetupResponse.
In order to make use of this feature, use the following parameter in enb.conf
Example:
gtp_advertise_addr = 213.61.141.82

Reimplement batch-based background object/memory pool
...
Main changes:
- addition of pool utilities
- The node size/alignment and batch allocation threshold are now runtime arguments
- object pool and memory pool are not anymore based on the same class.
The object pool cannot use intrusive free list because it would overwrite the object
memory

Enhance RRC eNB events:
...
- Implement a common event "log_rrc" for all RRC events and discriminate by procedure using an enum.
- Log events for connection, reestablishment, reconfig, reject and release.
- Log the corresponding ASN1 message used by each procedure.
- Redefine the JSON object for this event to match the new structure.
Fixed a compilation error detected by the static analyzer in gcc9.3 where bounded_vector::data() was using taking the address of the internal buffer which confused it, prefer to use the data method of std::array.

this patch replaces the std::vector type used in the interface between

data type is a configurable but fixed-size vector.
The RLC AM doesn't need to dynamically allocate the vector for every SN but
uses the tx_window for storage.

enb,rrc: delay UE release after RLC maxRetx
...
this fixes the eNB behaviour when RLC signals maxRetx reached.
By directly releasing the UE, we ignore the fact that the UE
could still have the reestablishment counters running, so
could attempt a reestablishment, which would result in a reject
because we would have destroyed the UE context too early.
this patch delays the removal of the UE to wait at least
until the reestablishment timers are expired.

- 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.

PDCP PDUs. This includes:

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.

mac_pcap: refactor MAC PCAP and include NR RAT into same object

after adding the thread-safe PCAP writer functionality to the EUTRA

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.

when a TPC is encoded

avoid sched_ue dangling pointer
...
With the sched feature that allows scheduling in TTIs
ahead of time, there is no guarantee that when
the tti arrives to generate a sched result, the stored
raw sched_ue pointers are still valid. For this reason,
I now store the rnti and check if the rnti still exists.

This commit addresses an issue where if a UE requests a release for
circuit switched fallback, but the sib7 carrier freqs info list is not
configured, the eNodeB would crash with a segfault due to attempting
to access an element from an empty list. This commit adds explicit
checking to handle the empty list case. If the list is empty, no
redirect carrier info is added to the connection release message and
the UE must scan for the fallback network itself.

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
