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.

Andre Puschmann f1e6a975de thread_pool: fix concurrent access of state variable 
the thread workers need access to their current state to exit properly
when they are set to state STOP. However, since the state is kept in
a std::vector for all workers, it seems more appropiate to add a per-thread
running variable rather then mutexing the entire vector.

Francisco f2a56c9139 simplification of multiqueue design. 
- the consumer does multi-staged waiting:
  1. spins first across all queues in a RR fashion
  2. each queue access is done with a try_lock.
  3. if the try_lock fails, it increases the number of spins needed
  2. if no queue had data, the consumer sleeps for 100 usec.
- no differentiation between queues, in terms of notification features

Andre Puschmann 21b3635ae4 rlc_am_lte: refactor retransmit_pdu() to send different SNs 
it seems that different SNs should be retransmitted depending
on the actual situation. In case of pollRetx timer expiration,
vt_s - 1 should actually be resent.

This patch prepares the function to accept different SNs but
leaves it to send vt_a by default. The RLC AM test would need
to changed as well to not fail.

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.

The patch determines the correct size before passing the opportunity to RLC.

It also improves logging in error case by using the MAC logger instead of

Andre Puschmann 0fdcea2924 rlc_am: count every segment retx as a full retx for this SN 
previously we were only counting retx if we retx the start of a segment.
this could lead to unwanted behaviour, i.e., not counting retx
correctly and thus not triggering the maxretx attempt, if the receive
always sends NACKs with a SO_start.

The RLC spec is not clear on how this should be handled correctly but
IMHO using an integer number of retx is reasonable, even for segments
that might be retransmitted more often.

The alternative of using a fractional retx counter that may be increamented
proportional to the segment size that is retx is another alternative
but considered too complex to implement (and test correctly).
