this is a rather large commit that is hard to split because
it touches quite a few components.
It's a preparation patch for adding NR split bearers in the next
step.
We realized that managing RLC and PDCP bearers for both NR and LTE
in the same entity doesn't work. This is because we use the LCID
as a key for all accesses. With NR dual connectivity however we
can have the same LCID active at the same time for both LTE and NR
carriers.
The patch solves that by creating a dedicated NR instance for RLC/PDCP
in the stack. But then the question arises for UL traffic on, e.g. LCID 4
what PDCP instance the GW should use for pushing SDUs. It doesnt' know
that. And in fact it doesn't need to. It just needs to know EPS
bearer IDs. So the next change was to remove the knowledge of what
LCIDs are from the GW. Make is agnostic and only work on EPS bearer IDs.
The handling and mapping between EPS bearer IDs and LCIDs for LTE
or NR (mainly PDCP for pushing data) is done in the Stack because
it has access to both.
The NAS also has a EPS bearer map but only knows about default and
dedicated bearers. It doesn't know on which logical channels they
are transmitted.
general-purpose method for lower layers to signal protocol
failures to higher layers, i.e. RRC.
In the current case, implement a direct release of the UE (enb) or
a reestablishment (UE).
this is an attempt to fix#2850 by defering the transmission of
the connection setup complete until the PHY has applied
the dedicated config in the connection setup.
* Replaced UE logger in the ue class.
* Replaced loggers in the main phy class and prach.
* Replaced loggers in phy common and ta_control.
* Replace loggers in cc and sf workers.
* Replaced loggers in intra_measure, scell_recv, search, sfn_sync, sync.
* Remove last uses of the old loggers in the main phy class.
* Remove stray newline in logs.
* Replaced loggers in ue gw.
* - Started to replace loggers in the ue stack.
- Replaced loggers in usim and pcsc.
- Adapted nas and usim tests.
* Replace loggers in nas.
* Added missing log init calls in two previously modified tests.
* Replaced logger in nas idle procs.
* Replaced loggers in nas emm state.
* Replaced loggers in tft packet filter and adapted tft test.
* Replaced loggers in main RRC class.
* Replaced loggers in RRC cell.
* Replaced loggers in RRC meas.
* Replaced loggers in rrc procedures.
* Started logger replacement in MAC layer, more precisely in demux and dl_harq classes.
Been unable to inject loggers in construction for dl_tb_process due to very weird static assertions in the std::vector code being the type not constructible which is not true, so instead use the main MAC logger directly.
* Replaced loggers in mac mux class.
* Replaced loggers in mac pro_bsr.
* Replaced loggers in mac proc phr.
* Replaced loggers in mac proc SR and RA.
* Replace loggers in mac UL HARQ.
* Replaced loggers in main ue stack class.
* Fixed nas test crashing due to a null string.
* Ported mac_test to use the new loggers.
* Removed TTI reporting for the PHY log as the old logger did.
* Replaced loggers in UE phy tests.
* Configure loggers in nas_test.
* Replaced loggers in rrc_meas_test.
* Replaced loggers in rrc_reconfig_test.
* Added missing newline in tft_test.
* Fix compilation errors in TTCN3 tests.
* Fix linker error detected in CI and warning.
* Replaced loggers in TTCN3 tests.
* Fix a text replace error in some log messages.
* Remove trailing newlines from log entries.
* Remove old logger from rrc.
* Flush backend before printing the test status.
* - Fix compilation error from previous rebase.
- Remove trailing newlines from some missing log entries.
* Refactor NR resource allocation classes. Use DCI instead of grant for dummy PDSCH UE/eNB test
* Minor refactors in NR workers and ue_dl
* Fix include issues
* fix compilation issues
* Make PHY non-blocking and fefactor HO procedure
* makes entire PHY non-blocking through command interface
* adds dedicated queue for cell_search/cell_select commands
* refactor HO procedure to run faster, in one stack cycle. Looks closer to the specs
* force ue to always apply SIB2 configuration during reestablishment
* Run update_measurements in all workers

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
