Andre Puschmann 9c4146442a mac,phy: refactor NR MAC/PHY UL data passing interface
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

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.

this potentially fixes the issue we see during HO and RLF

The issue happens because buffered DL PDUs are delivered to
RLC after reestablishing RLC that confuse the receiving
RLC entity bc the sequence numbers are very high, as opposed
to begin with zero again after reestablishment.

This caused issues because the buffer state for all LCG that

one LCG does have data to transmit.

Andre Puschmann 082e002b67 nas: fix airplane mode simulation
the current implementation was somehow broken after a
NAS refactor. It was undetected because we didn't really
use it.

this fixes the simulation by using a single timer to simulate
airplane mode transitions.
the timer is rearmed in the timer_expire() function
if the correspondig event is set.

Has been tested to work well with, e.g.:

--sim.airplane_t_on_ms 5000 --sim.airplane_t_off_ms 10000

Andre Puschmann fd5cde525c proc_bsr: fix race condition in BSR reporting
fix for #1934

This fixes a race condition between Stack thread and DL
PDU processing that lead to updates of the RLC buffer that
are undetected by the BSR routine.

What happens is that in a UL SCH PDU all outstanding data is transmitted
and and a LBSR with all zero buffers is sent.

14:39:47.327301 [MAC ] [D] [ 3793] BSR:   LCID=3 old_buffer=59
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

14:39:47.331941 [MAC ] [D] [ 3794] Update Bj: lcid=3, Bj=-1752
14:39:47.331951 [MAC ] [D] [ 3794] BSR:   LCID=0 update new buffer=0
14:39:47.331960 [MAC ] [D] [ 3794] BSR:   LCID=1 update new buffer=0
14:39:47.331964 [MAC ] [D] [ 3794] BSR:   LCID=2 update new buffer=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.

a BSR has already been sent.

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

this fixes #1791 which was caused by a race between
the PHY workers preparing a new UL-SCH PDU and the Stack resetting
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.

Andre Puschmann b616944a13 ue,rrc: fix security config during HO/reestablishment
we fix a number of very related issues for HO/reestablishment
in the success/error case:

* this patch removes the hard-coded check that intra-cell HO aren't
allowed. There are cases where eNBs use this method to update
the security context.

* the patch also fixes an issue after failed HO where the security context
of the source eNB should be used for the reestablishment.

* update security keys according to specs when mobilitycontrol
indicated change of key

Andre Puschmann c16ac6c890 ue_stack: only push sync event to event queue is stack is still running
stopping the UE in ZMQ mode caused a dead-lock because the Stack was
stopped before the PHY causing the sync queue to overflow. Since we
use a queue-length of 1 in ZMQ, mode, the PHY sync thread was blocking to
push a new sync event while the stack thread was already stopped.

this patch makes sure no new sync events are queued after the stack has
been terminated.

Andre Puschmann aec18a93d1 mux,bsr: refactor UL buffer status reporting
this patch fixes the UL BSR as per TS 36.321, it includes following
main changes:

* report UL buffer state to reflect the UEs transmit buffer after
  the MAC UL PDU containing the BSR has been built.
  In other words, if the UE, for example, can transmit all outstanding
  data in an UL grant, it will not report any pending data to transmit.

* refactor MUX routines and subheader space calculation

we need to remove the subheader again before packing the PDU.
