Andre Puschmann 6c82d63aa6 remove legacy PNF/VNF code
the code hasn't been maintained for a while an likely needs to be
adapted for a real-world scenarios.

in order to avoid having to maintain two MAC/PHY interfaces we
remove the code from now.

Andre Puschmann 4379c20eb9 rlc_am_lte: avoid locking of Rx mutex twice when generating status PDU
call reset_status(), which now is an private method directly when
building a status PDU. No need for the Tx side to call Rx again.
3 years ago
Andre Puschmann 53a7dc78ee rlc_am_lte: replace do_status boolean with atomic
the do_status is queried from the Tx code frequently. To reduce
chances to delay the execution because the RLC Rx side is currently
holding the mutex we can use an atomic.

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.

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 f1e6a975de thread_pool: fix concurrent access of state variable
the thread workers need access to their current state to exit properly

running variable rather then mutexing the entire vector.

Francisco f2a56c9139 simplification of multiqueue design.
- the consumer does multi-staged waiting:

  2. each queue access is done with a try_lock.

  2. if no queue had data, the consumer sleeps for 100 usec.

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

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.

Andre Puschmann ceacf8508d rlc_am_lte: fix handling of maxretx
this patch fixes the actions/handling after RLC detected
maxRetx reached for a given SN.

According to the TS, RLC should only inform upper layers and
not try to recover from the event itself.

As a consequence, we won't manipulate the Tx or Rx window.
As a result of this, we might retransmit a SN more than
the specified amount of times.

It's the task of RRC to reestablish the bearer to recover
from that.

inspired by accepted (but not yet merged) PR to include the
(unique_)byte_buffer_t for MAC/PHY interfacing, this patch adds
a few more useful bits to that. Buffer management for UL data is now
done in MAC and only a pointer to the data is passed in the UL action.

* Move Tx softbuffer to MAC (until UL HARQ class is ready)
* Remove temparal data member in cc_worker
* Remove memcpy after packing MAC PDU
