Francisco Paisana 42cdc5e340 Allocate all the leftover bytes of the TBS to last allocated MAC SDU. 
Fix the way the RLC header is accounted for depending on the bearer id.
For instance, the SRB0 does not require any RLC header.

Francisco Paisana 44a9ad76f1 avoid sched_ue dangling pointer 
With the sched feature that allows scheduling in TTIs
ahead of time, there is no guarantee that when
the tti arrives to generate a sched result, the stored
raw sched_ue pointers are still valid. For this reason,
I now store the rnti and check if the rnti still exists.

Francisco Paisana eafc003671 Altered the way the generation of the scheduling decision for a given

Francisco Paisana c46402c836 fix phy configuration during handover on srsenb. The function srsenb::rrc::ue::fill_scell_to_addmod_list assumes that the phy_cfg of the PCell is up-to-date, which was not the case.

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 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.

Andre Puschmann a0e4b18507 enb_mac: pre-allocate UE object for quicker PRACH/RAR handling 
we've seen long delays in handling PRACH on low-power devices
such as the RPi4. This was mainly caused by long delays
in creating the UE object on the fly during PRACH handling.

This patch pre-allocates one UE object that is then used
during the PRACH.

Also avoid MAC calling RLC for each SIB and call RRC directly.

Andre Puschmann fef6893ce4 make user activity handling independent of system time 
this commit removes the getsystime() call from the activity handling.
it uses a single timer per UE to handle its activity.

three different timer values exist. one for the Msg3 reception. This
is like before and is quite low to quickly remove fake UEs from the
RRC. The second is a generic value (set to 1s for now) that covers
the entire UE configuration phase where multiple messages are sent
back and forth until the UE is fully set up and the default
bearer runs. From there on, the UE inactivity timer is used which
may be much bigger than 1s.

Harald Welte 2e426948fe [ENB] Add CFSB support 
This commit introduces CSFB (circuit switched fall-back) capabilities to
srsLTE.  Actually, all the eNB has to do is to send a
RrcConnectionRelease with the RedirectedCarrierInfo IE.

The MME triggers this by the S1AP CS Fallback Indicator IE, which may
be present either in the Initial Context Setup Requst or in the
UE Context Modification Request.

As srsLTE has no support for the UE Context Modification Request at all
yet (!), basic support for this message is introduced in this patch.

Both Mobile Originated and Mobile Terminated CSFB with a coupel of
different UE models have been verified using this patch in a setup
consisting of srsENB attached to an undisclosed EPC connected via SGsAP
to a complete  Osmocom 2G network.

Andre Puschmann 58763fb714 stack: move initialization of log object into ctor 
this fixes the issue when the stack is torn down if, for example,
the radio couldn't be loaded correctly. it will hence call stop() on all stack
components which are not initialzized yet, and logging therefore doesn't work.
the log object is know during contruction time and therefore can be passed
in as soon as possible.
