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

Francisco Paisana 97133894e6 the Ocs value used in the measReport triggering decision was not being set correctly. The enum of the cell individual offset in the measCfg was being cast to an int and stored. Instead what we want is to store the actual offset value using the ASN1 enum->number lookup table. 2020-09-18 13:17:32 +01:00

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

Andre Puschmann 6364a4513c mac_pdu: fix issue when packing CE but no space left in PDU
we've not checked the return value when adding a new CE, like BSR or PHR,

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

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

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.

First of all, with this the NAS conformance tests pass with ciphering and

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.

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 dc4be1b856 fix overwriting dedicated_info_nas in connection_request_proc
this fixes an issue in the step() function of the connection_request_proc
in which the dedicated_info_nas message was passed to RRC without
checking if its actually valid or not, i.e. contains a message at all.

because this check was missing and the step() function could be called
multiple-times, the function would overwrite the dedicated_info_nas
in RRC, and therefore causing the connection setup complete to fail

this fixes a bug in which the contention resolution timer expired

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

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

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.
