Pedro Alvarez 96f39da5d7 Fixes for airplane simulator. 4 years ago
Pedro Alvarez 14844a168a Created new class to hold all NAS states for the NAS state machine. Added EMM-DEREGISTERED substates and EMM-REGISTERED substates.
Decoupled PLMN selection, attach request and service request. Removed RRC connect procedure from NAS.

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

Daniel Willmann 925225dbeb Implement Close UE Test Loop/Complete messages
This commit implements support for the CLOSE_UE_TEST_LOOP message.
Currently the mode is not saved and looping the data is not implemented.
Only the *_COMPLETE message is sent back as a response.

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 94c6034339 nas: rename start_attach_request to start_attach_proc
this is to better differentiate from "send_attach_request" that
only packs and send the actual attach request message. The
entire attach procedure may include PLMN search, etc.

Andre Puschmann 3f10224729 refactor airplane mode simulation and move to NAS
- move handling to NAS
- use switch off to enable airplane mode (don't wait for EPC response)
- add tiny FSM to control airplane mode activation/deactivation
- only start on/off counter after state has been entered

Francisco Paisana f2d88e5a5b simplified NAS rrc connection request procedure
move non-type-specific methods of proc_t to its base class.
procedure state machine was simplified via a future-type. Now procedures dont get stuck until the user reads the procedure outcome.
made the NAS procedures more event trigger/reaction-based.

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

Andre Puschmann 5faa819dcd fixing uninitialized class members found by coverity 5 years ago
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. 5 years ago
