Andre Puschmann f0818275f0 ue,phy: reduce log level when 2nd grant for same PID is registered 
this resolves issue #2277 in which a warning was logged when
the CC worker decoded a 2nd phantom PDDCH.

It's difficult to avoid this 2nd PDDCH without addional computation
that we don't want add at this stage.

Rather than filtering out the Warning in the log post-processing,
we reduce the log level to info.

Andre Puschmann 8e13f04684 mac_pcap: refactor MAC PCAP and include NR RAT into same object 
after adding the thread-safe PCAP writer functionality to the EUTRA
MAC object it became clear that we don't wont to replicate the
same for the NR object.

This patch therefore refactors the class that now supports both EUTRA and
NR rats. The old mac_nr_pcap.[h/cc] has been deleted. All test-cases
and usages now use the new object that needs to pass the RAT type in
the ctor.

this patch addresses the last open point of #2160

Andre Puschmann cc750d96ee nas: when receiving detach request, don't enter plmn_search automatically 
this patch fixes an issue with TC_9_3_1_17 after the "send attach in RRC connected" issue
has been fixed. The TC failed because the UE would always attempt to re-attach, even
after receiving an explicit detach request WITHOUT re-attach from the network.

According to TS 24.301 Sec. 5.5.2.3.2 the handling of that message largely depends
on the detach cause sent by network. Since we don't currently parse and handle
that the simplest solution here is to just enter deregistered:::null.

The patch is also part of the fix for issue #2237
 4 years ago
Andre Puschmann 2576ada9e1 nas: do not abort attach procedure if RRC is already connected 
this is an attempt to fix issue #2237 that cause the UE to fail to
attach because the attach request wasn't resent after T3410+T3411
expired.

this was only because RRC wasn't idle at that stage and the attach
request generation was aborted.

The patch fixes this by passing the NAS PDU directly to RRC in
connected state.

The patch also converts the blocking PDU alloc to a non-blocking one.

are still executed in the PHY worker thread but the state machine
manipulation is defered.

prints "n/a" in case the scells aren't set yet.

Andre Puschmann 2be85217fd mac,ue: reset demux when restting MAC 
this potentially fixes the issue we see during HO and RLF

The issue happens because buffered DL PDUs are delivered to

RLC entity bc the sequence numbers are very high, as opposed
to begin with zero again after reestablishment.

14:39:47.330600 [MAC ] [I] [ 3793] UL LCID=3 len=58 LBSR: b=0 0 0 0

Note that "old_buffer" isn't set to zero here.

At the same time (same TTI), the MAC PDU processing thread handles DL-SCH PDUs
that may generate new UL PDUs:

14:39:47.330749 [RLC ] [I] DRB1 Tx SDU (54 B, tx_sdu_queue_len=1)
14:39:47.330762 [RLC ] [I] DRB1 Tx SDU (54 B, tx_sdu_queue_len=2)
14:39:47.330775 [RLC ] [I] DRB1 Tx SDU (54 B, tx_sdu_queue_len=3)
..

Those PDUs are "new data" since the previous buffer state was zero.

Here is the race now between the threads, at the end of the bsr::step() function
old_buffer of each LCG is updated with the previous new_buffer, so
the buffer state of LCG=2 is now 59.

Now MAC starts the next TTI:

14:39:47.331910 [MAC ] [D] [ 3794] Running MAC tti=3794
14:39:47.331928 [MAC ] [D] [ 3794] Update Bj: lcid=0, Bj=0

14:39:47.331971 [MAC ] [D] [ 3794] BSR:   LCID=3 update new buffer=335
14:39:47.331976 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(0)=0
14:39:47.331980 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(1)=0
14:39:47.331984 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(2)=59
14:39:47.331988 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(3)=0
14:39:47.331993 [MAC ] [D] [ 3794] BSR:   LCID=0 old_buffer=0
14:39:47.332000 [MAC ] [D] [ 3794] BSR:   LCID=1 old_buffer=0
14:39:47.332003 [MAC ] [D] [ 3794] BSR:   LCID=2 old_buffer=0
14:39:47.332007 [MAC ] [D] [ 3794] BSR:   LCID=3 old_buffer=335

And since the buffer state of LCG=2 isn't zero, the new data for LCID=3 of that LCG is considered.
So effectivly, the BSR missed the "empty" buffer state for a fraction of time and doesn't
consider the outgoing data generated in the same TTI as new. It therefore
doesn't transmit a BSR.

Andre Puschmann 465c3d9186 proc_sr: remove info log when starting SR proc 
this was a very noisy log that was printed in pretty much
every TTI because the BSR procedure starts a SR whenever
it needs to send a regular BSR. The SR is canceled when a UL
grant arrives but the log line stays there.

Since we are printing a log when we actually signal a SR
to the PHY, this line is not needed.

Andre Puschmann 1e3ad5b0dc proc_bsr: fix high priority channel trigger logic 
this fixes the trigger logic for periodic BSRs. Previously we
would always trigger the "new data for highest priority LCID"
whenever new data becomes available for a LCID for which
a BSR has already been sent.

However, a BSR should only be sent if the priority is in fact higher
(lower int number).

Andre Puschmann debbab93e8 mac_test: cosmetic change 4 years ago
Andre Puschmann e89254ad1f mac_test: fix mac_ra_test according to BSR changes 
the BSR routine had a bug in which it would generate a BSR even
before the reTx timer expires if new data becomes availble
for a LCID that already had data and a BSR was already sent.

The RA test here relies on a BSR in the generated MAC PDU to pass.

However, since after fixing the BSR bug the PDU the MUX unit
no longer generates a BSR, we need generate data for a LCID
which has higher priority than the one for which a BSR has
already been sent.

this fixes #1791 which was caused by a race between

the MAC, which in turn resets the HARQ processeses, which cleared
the buffer and set the length to zero.

Not explicitly clearing the buffer on a HARQ reset seems to be
fine since the PHY worker clears the buffer before starting to
pack a new PDU anyway.

Andre Puschmann eeb2b904aa ue,rach: fix failing RACH proc when Msg3 grant RNTI matches current CRNTI 
this was preventing that the Temp-CRNTI used in the RAR to be identical
to the currently configured C-RNTI of the UE.

The issue simply was that the RACH procedure was declared successful too
early, even before the Msg3 UL grant was filled with the Msg3 content.

The patch moves the logic that detects the successful completion of
the RACH procedure below the Msg3 packing.

stopping the UE in ZMQ mode caused a dead-lock because the Stack was

been terminated.

Andre Puschmann 24dfb03b9d rrc: defer manipulations of the RLC/PDCP arrays 
all calls that manipulate the RLC and/or PDCP arrays suffer
from a high deadlock risk if a PHY worker holds the RLC
AM Rx mutex at the same time when the stack wants to carry
out this reconfiguration.

this applies to RRC Reconfigs, but potentially also to RRC Connection
Reestablishment or even RRC Connection Setup, although this should
seldom be the case.

By breaking the call stack between RLC->PDCP->RRC->RCL and
carrying out the reconfig as a single task without holding the
RLC readlock the deadlock should not happen anymore.

This should fix issue #1593

Andre Puschmann a7911f0dab pdcp,rlc: refactor SDU queueing policy 
this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer.
the previous design had issues when packets have been generated at a higher
rate above the PDCP than they could be consumed below the RLC.

When the RLC SDU queues were full, we allowed two policies, one to block on the write
and the other to drop the SDU. Both options are not ideal because they either
lead to a blocking stack thread or to lost PDCP PDUs.

To avoid this, this patch makes the following changes:

* PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full
  * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP
* remove blocking write from pdcp and rlc write_sdu() interface
  * all writes into queues need to be non-blocking
  * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC
* log warning if RLC still needs to drop SDUs
  * this case should be avoided with the monitoring mechanism

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.

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.
