Andre Puschmann a5c0f96fa7 srsue: limit sync queue length to 1 for ZMQ radio 
apply same change that we've done on the eNB also on the UE
to avoid the PHY processing TTIs faster than the stack.

Without that, we see lots of those in the logs:

...
08:39:17.580325 [STCK] [W] Detected slow task processing (sync_queue_len=7).

Andre Puschmann cf12c98630 srsue: exit early if radio can't be initialized 
since the radio is the first component we initialize, it is safe to
exit the ue::init() straight away, as no other layers use any handles yet
 4 years ago
Andre Puschmann e981d5ee70 rrc,ue: refactor wait conditions before transition to RRC idle 
before entering RRC idle, after receiving a RRC connection release for example,
we need to wait until the RLC for SRB1 or SRB2 have been flushed, i.e.
the RLC has acknowledged the reception of the message.

Previously we have only waited for SRB1 but the message can also be received on SRB2
and in this case both bearers need to be checked.

The method is now streamlined to check both SRBs and is also used when
checking the msg transmission of an detach request.

chaolinyi bbe25a00d4 Update proc_ra.cc to bugfix RA-RNTI calculation 
Bugfix the wrong ra_rnti calculation in ra_proc::state_pdcch_setup.
According to TS 36.321 Subsection 5.1.4 Random Access Response reception, we can see the formula on RA-RNTI, which is,
    RA-RNTI= 1 + t_id + 10*f_id,
where t_id is the index of the first subframe of the specified PRACH (0≤ t_id <10), and f_id is the index of the specified PRACH within that subframe, in ascending order of frequency domain (0≤ f_id< 6). Then, reading the srslte source code, we can see that, the code should bugfix. 
BTW, the wrong code can run normal for LTE_FDD, causing of the info_f_id = 0; but it should be wrong, when it is LTE_TDD.

Andre Puschmann 1e0c8ead4c srsue,sync: fix TTI gap calculation and reporting 
The current TTI gap calculation assumes strict continuity
of radio time stamps, even when retuning, changing sample rate, etc.

This is certainly desireble but not necessaritly the case and may cause
issues when negative time gaps or too large gaps are detected and reported
to the stack.

this patch makes the assumption that valid TTI jumps are between 1ms
and 1s and that larger gaps are the result of screwed time-stamps
or too long radio operations.

Andre Puschmann acc2948b45 nas: fix security handling 
First of all, with this the NAS conformance tests pass with ciphering and
integrity turned on. Before only integrity was working.

Mainly the NAS was applying the integrity protection and/or ciphering
incorrectly because it wasn't taking the secuirty status of the PDUs
into account. Some where already correct, some not. The patch
streamlines the handling for all outgoing messages.

it through log_h->info()

i've moved the old macro into a new header and used as as much
as possible. there are still places in the code where similar
macros are used but we would need to change the variable name
to replace them

Andre Puschmann 9e113f8b27 pdcp: allow to configure security for rx/tx seperately 
previously PDCP security (integrity and ciphering) could only
be enabled for both Rx and Tx at the same time.

this, however, caused an issue during the conformance testing in which,
in TC_8_2_1_1() for example, the eNB sends a SecModeCommand and a
RRC Reconfiguration in the same MAC TB. In this case, the eNB
needs to be able to enable DL security right after sending the SecModeCmd
in order to send the RRCReconfig encrypted. However, enabling UL security needs
to be postponed until after the SecModeComplete is received.

This patch allows to enable PDCP security for rx/tx independently if
that is needed. The default way is like before, enabling it for tx/rx at
the same time.

Andre Puschmann 8d284f48bd cancel RA when receiving contention resolution in wrong state 
this fixes a bug in which the contention resolution timer expired
and the RA proc entered the BACKOFF state.
In the same TTI, a MAC PDU with the contention reslution ID is received
and the already aborted RA procedure succeeds. Unfortunatly with the
wront c-rnti which has already been reset before. See log excerpt
below:

Andre Puschmann c7343cf6d8 protect sf_buffer from overrun in receive_samples 
this patch adds a buffer len paramter to the receive_samples() call
that protects the (also) provided buffer from overflowing.

currently each call to srslte_ue_sync_zerocopy() which then calls receive_samples()
relies on a buffer that is "big enough". But that buffer is sometimes
2 subframes, sometimes 3 or 5, sometimes has space for the maximum PRB size, sometimes
only for 6 PRBs (i.e. during cell search).

By extending the interface to pass the buffer size we can make sure that
only samples are received that actually fit inside the provided buffer.

Pau Espin Pedrol 4949df257e Proper shutdown on SIGHUP 
If a process exits and has a controlling terminal, everything under
it gets a SIGHUP by the kernel. That's the case for instance when
running a srsUE over ssh with some specific parameters. As a result,
when the ssh client is killed, SIGHUP is sent to srsUE, which will be
killed immediatelly without proper release, which means in turn that log
buffers are not flushed.
Let's do proper shutdown when SIGHUP is received so that everyone can
get log files.

Andre Puschmann 2a46413121 during cell search don't configure found cell as serving cell 
this fixes an issue in which, during cell search, the sync code
itself would set the serving cell whenever it found a new cell.

instead, only report the found cell to RRC and keep the sample
rate at 1.92 MHz. RRC may select a new serving cell and then tell
PHY to camp on it.

Andre Puschmann 6ec573987a remove default value for 'blocking' param from pdcp::write_sdu() 
there were two defaults and one was shadowing the other. This
commit removes both defaults and uses blocking-mode for RRC
calls to PDCP in the UE. The eNB write_sdu() uses the non-blocking
mode by default. We have to review the eNB's RRC perhaps and use blocking
there too and non-blocking only for data plane

Andre Puschmann 3127f59b4c wait with init of GUI until cell is found and initialized 
with the stack refactor we've introduced a regression in which
the GUI was started too early when no cell was found yet.

this caused the GUI to be initilized with only one Tx port. When connecting
to a cell with ports, the GUI plotter would then write
into unitialized memory.
