this should facilitate easier log parsing and plotting
if the cell measurements _always_ include the PCI, even
in the case of the serving cell

Andre Puschmann ddbf4e1645 metrics_stdout: print new table header if neighbour cells change 
this fixes an issue where the stdout metrics isn't readable if the only
neighbour cell gets removed during the 10s where no table header is printed.

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 6827c2df21 rrc_meas: disable layer3 filtering until quantity config is received 
the filter alpha was initialized to zero by default which causes an
issue because the first measurement for a cell can't be updated,
because the filtering function will always return the current value.

According to 36.331 Sec 5.5.3.2 Note 2, a k-value of 0 should turn
off filtering, which should be used as the default value until
an update is received from the network.

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 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.

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.

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 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.

Xavier Arteaga 67935d2b99 SRSUE: RRC blocks MAC RA procedure during reestablishment 2019-11-28 16:33:35 +01:00
Andre Puschmann 8ef0d6c6ca do not automatically consider cells for which a measurment has been received as "in sync" 
the in_sync flag has been misused in some parts of the code
receiving a PHY measurement for a cell does not automatically
mean that we are "in sync", as it is used in RRC as a condition
to indicate if we are camping on cell

the in_sync/out_of_sync condition should only be altered by the
corresponding functions sent from the PHY for the currently selected
cell (and not automatically for all cells)

the commit also removes the deletion of cells which are not "in sync"
from the list of neighbor cells. Instead, RRC calls a clean-up function
peridically that deletes old cells eventually.

the log object is know during contruction time and therefore can be passed
in as soon as possible.
