Andre Puschmann 483a216bd5 ue,stack: refactor handling of radio bearears in UE stack 
this is a rather large commit that is hard to split because
it touches quite a few components.

It's a preparation patch for adding NR split bearers in the next
step.

We realized that managing RLC and PDCP bearers for both NR and LTE
in the same entity doesn't work. This is because we use the LCID
as a key for all accesses. With NR dual connectivity however we
can have the same LCID active at the same time for both LTE and NR
carriers.

The patch solves that by creating a dedicated NR instance for RLC/PDCP
in the stack. But then the question arises for UL traffic on, e.g. LCID 4
what PDCP instance the GW should use for pushing SDUs. It doesnt' know
that. And in fact it doesn't need to. It just needs to know EPS
bearer IDs. So the next change was to remove the knowledge of what
LCIDs are from the GW. Make is agnostic and only work on EPS bearer IDs.

The handling and mapping between EPS bearer IDs and LCIDs for LTE
or NR (mainly PDCP for pushing data) is done in the Stack because
it has access to both.

The NAS also has a EPS bearer map but only knows about default and
dedicated bearers. It doesn't know on which logical channels they
are transmitted.

Andre Puschmann 7113e55d53 rlc: refactor RLC entity to use smart pointers for holding bearers 
this patch mainly modernizes the bearer creation to use smart pointers.
that allows to simplify the error handling.

ue_stack is changed to match new interface. This commit compiles
but doesn't work.

Andre Puschmann e1fb58d76e rlc_um: reduce log level for message handling lost PDUs 
when a lost PDU is detected a warning will be logged. In theory
this could be info as well but a warning may help to detect issues
in tests. The same event causes multiple other warnings to be logged,
which is very spammy. The patch reduces the log level for
those messages to info.

Andre Puschmann 83bf5dcd49 rlc_am_lte: reduce time holding Tx mutex when processing status PDUs 
the patch is a re-implementation of the customer-specific optimization
we did in order to reduce the time the RLC holds the Tx mutex when
processing an incoming status PDU.

The patch makes sure to never operate on a raw mutex but instead
uses the deadlock-avoiding RAII lock.

Andre Puschmann 19f30aa652 rlc_am_lte: fix handling of out-of-order status PDUs 
before processing incoming status PDUs we should be checking
if the ACK_SN falls within our current Tx window. If not the PDU
will be dropped.

Without the check we were incorrectly processing the status PDU
and because the sequence number wrap around wasn't working
correctly if ACK_SN is smaller than vt_a we were corrupting
our Tx window.

Andre Puschmann c0be8187c8 rlc interface: convert entire read_pdu() interface to return uint32_t 
we had it returning int but had a bug in using the return value properly,
i.e. handling when -1 was returned in RLC TM.

Thinking about it more, it doesn't make sense to have a negative return
value here anyway. Either the RLC can return a PDU or not. If it can't the
returned lenght is zero.

Andre Puschmann a36e0477b8 rlc_am: fix status PDU packing when grant size isn't enough to send full report 
when a small grant is provided it might not be possible to fit a full status
PDU. This is currently detected while packing the PDU.

In order to avoid sending potentiall contradicting status info to the sending
entity, the fix makes sure to only transmit a small PDU acking what really
has been received so far.

This might not be optimal in terms for retx but will not corrupt any
state.

Andre Puschmann f22f4b4fbd rlc_am: fix potential stalling in RLC transmitter 
it turned out that a certain order of events can lead to
a RLC transmitter stalling because even though unacknowledged PDUs
are queued, none of them was actually considered for retx.

This can happen if a pollRetxTimer expires for a SN that, meanwhile,
has already been acknowledged. The positive lead to the deletion of
the SN from the Tx window.

The fix makes sure that when a retx for a unexisting SN is requested,
the sender will consider the next unacknowledged SN instead.

Andre Puschmann 02cceee997 rf_zmq_imp: revert 28399dd876 and fix unit 
although the manual test with Amarisoft eNB worked fine it seems
the delay is still needed in the default case. Over 50% of the
tests failed in the nightly with:

[zmq] Error: tx time is 0.067 ms in the past (138240 < 139776)
[zmq] Error: tx time is 1.100 ms in the past (184320 < 209664)

While this usleep() should increase the pass likelihood it
still doesn't guarantee error-free runs, so we might need
to revisit it again as some stage.

herlesupreeth 0f06ec0d9c 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

Now we store it into a configurable size node that can store a fixed size string, otherwise it falls back to std::string.

Andre Puschmann 48537f3fe7 pdcp,rlc: increase number of PDCP SDUs for notification from RLC 
the current value of 256 limits the number of PDCP SDUs that can be
notified from RLC. The limit is quickly hit when too many SDUs
are in flight. This can cause unwanted log entries and weird PDCP
behaviour.

the patch increases the value to 1024, which still can be too few if
many smaller SDUs are traveling.

The patch also set the log level to warning to quicker spot
misconfigs in logs.
