Andre Puschmann 0a16f48869 gw: fix race condition
GW thread was checking the default_eps_bearer variable without
protection. RRC could update it when deleting DRB or receiving RRC
connection release.

Andre Puschmann 483a216bd5 ue,stack: refactor handling of radio bearears in UE stack
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.

* 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.

Andre Puschmann 082e002b67 nas: fix airplane mode simulation
the current implementation was somehow broken after a
NAS refactor. It was undetected because we didn't really
use it.

this fixes the simulation by using a single timer to simulate
airplane mode transitions.
the timer is rearmed in the timer_expire() function
if the correspondig event is set.

Has been tested to work well with, e.g.:

--sim.airplane_t_on_ms 5000 --sim.airplane_t_off_ms 10000

Andre Puschmann acc2948b45 nas: fix security handling
First of all, with this the NAS conformance tests pass with ciphering and
integrity turned on. Before only integrity was working.

Mainly the NAS was applying the integrity protection and/or ciphering
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 c5f52adfba nas: fix issue in which NAS wouldn't allow to attach once it failed
the main issue was the plmn_selected variable. the solution
was to create a function to enter the deregistered state that resets the variable
and performs all other actions that need to be performed, like clearing
EPS bearers.

The patch also extends the SS to support AT commands to enable/disable
data services and now succesfully passes TC_9_2_2_1_7

Francisco Paisana bb0dbf0f1c created a asn1 utils with helper functions and types related to the asn1. These types/functions will help isolate the rrc_asn1 lib from most of the layers, reducing this way the compile times, and leading to better isolation. This will also make the transition to NR smoother. I removed the asn1 types from the NAS and USIM interface so far. 6 years ago
