faluco dacf40f63e Delete move constructor and move assignment operator explictly for mac_pcap_base and s1ap_pcap classes.
Move emergency handlers header file into the support folder.

Refactored signal handling:
- Remove the dependency with the running static variable in the header file.
- Move implementations down to cc files.
- Allow specifying a new signal handler that will be used to stop the applications.
- Move signal handling files to support.

gnss_sync: fix timestamp to TTI conversion
* Improve reliability of timestamp to tti conversion

Difftime is not reliable as it might use 32 bit calculation, depending on the system. This leads to wrong frame numbers and subframe indices.
I encountered this Issue when testing the pssch_ue exampel on my system and the conversion from timestamp to frame number and sf idx was wrong.

* Improve GNSS Sync 

Added loop to check for GNSS alignment while syncing.
If the received GNSS signal is weak, synchronization errors might occur while syncing.

Andre Puschmann e563e5918e rf_imp: fail opening RF altogether if specified device fails to open
we've had a few runs in the CI where opening the specified RF device
failed but the eNB/UE still continued to run, just picking the next available
run. This led to false-positive tests.

The policy should be that whenever the user specified a RF device to
be openend, and this device fails, the whole process should fail and
the application should exit.

The auto-detection mode is still available but only if no device name
is specified at all.

Andre Puschmann cc2d71183e ue,phy,nr: fix race condition when setting UL grant for Msg3
the Msg3 UL grant requires the TTI in which the RAR has been received
to calcualte the correct timing. There was a race between PHY and Stack
thread.

This patch circumvents the issue by removing a PHY state member that only holds
the RAR Rx timing. In the new interface the RA proc passes the Rx TTI
to the PHY again when setting the UL grant so the PHY can calculate the
correct timing without any state.

after changing the retx counting we receive one SDU more than before
3 years ago
Andre Puschmann 7726acad41 rlc_am_lte: fix counting of retx of entire PDUs and PDU segments
this patch fixes a bug discovered in a real network where the DL CQI of a
user degraded repidly in very short time. A relativly big RLC PDU that
was still sent with the good CQI in a big grant now needs to be split
across many tiny segments because the CQI degraded so much.

The retx couting for each transmitted segment caused the retx counter to
reach maxRetx quickly.

With this patch we do not increment the retx counter for each transmitted
PDU or segment of a PDU but instead only increment the counter when
a given SN is added to the retx queue. This can happen either:
a) if the SN is negativly acknowledged and was not already on the retx queue,
b) no new data is available for tx and a SN is selected for retx.

This is in accordance with TS 36.322 which handles retx counting in section
5.2.1 according to the above description.

hold (e.g. by a thread processing rx PDUs) the generation
of the status PDUs is not taking too long and blocking the calling
thread. Instead the status PDU generation is deferred to the next
Tx opportunity.

It's a probabilistic approach that assumes that at some stage the
lock can in fact be acquired.

one of the unit tests does the following:

backend.start();
backend.stop();

the internal running_flag member could be set to true and then to false by the main thread before the worker thread calls do_work(). If this happens
the assert will be triggered, which is wrong and too conservative, so remove the assert.

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 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 878142843e rlc_am_lte: add further sanity check when creating status PDU
the test verifies that the ACK_SN of a status PDU falls inside the
rx_window of the receiver. If not, than the RLC state has been
corrupted and the status PDU is likely invalid.

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.
