Francisco 94efeab672 Optimization of sched_ue methods to derive required number of prbs to allocate to a rnti
This optimization has been achieved by:
- implementation of "false position method" root-finding algorithm
- application of the false position method in cc_sched_ue::get_required_prb_dl/ul(...)

The number of iterations in the worst case scenario, reduced from 100 to 5 with
the proposed algorithm.

Andre Puschmann fb83b5c307 enb: fix reestablishment with AS security enabled
this fixes RRC reestablishment with security turned on

the bearers, primarily SRB1, were reestablished before the "old"
security context was restored from the previous RNTI of the
reestablishing user.

this let SRB1 without proper security config. therefore the UE
couldn't decrypt the first response of the UE on SRB1 that was
already encrypted.

I now store the rnti and check if the rnti still exists.

Matt Johnson 00940f0dbf srsenb: Add inline documentation for sib7 in example configs 4 years ago
Matt Johnson e9eab89a6b srsenb/rrc: Avoid crash when CSFB requested but sib7 not configured
This commit addresses an issue where if a UE requests a release for
circuit switched fallback, but the sib7 carrier freqs info list is not
configured, the eNodeB would crash with a segfault due to attempting
to access an element from an empty list. This commit adds explicit
checking to handle the empty list case. If the list is empty, no
redirect carrier info is added to the connection release message and
the UE must scan for the fallback network itself.

as 3400 or 2.685 GHz is on the edge of band 7, some phones won't connect
to a 20 MHz cell on this EARFCN.

In order to simplify testing with other bandwidths we change the default EARFCN.

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

using ZMQ) the zmq-based radio to timeout. as a result
the rx/tx between UE and eNB stopped so the UE never reached

Andre Puschmann 06d31f46ba enb: set maximum allowed TTI difference between PHY and Stack TTI clocks for ZMQ
this fixes the issue where PHY and MAC threads, and the processing
of events therein, are drifting apart too much.

This patch effectivly enforces a strong wait on the PHY if the
stack thread is too slow in processing its tasks.

For RF hardware the default is still 8192 TTIs, for ZMQ 1 TTI is used.
