extend GW-NAS interface to signal test mode activation.
The method is a noop in the normal GW but is implemented in
the TTCN3 DUT according to TS 36.509 for Mode B
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.
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.
during deinit of the UE/eNB it could happen that the log_ptr
was already set to null but the stack thread was still accessing
it through log_h->info()
i've moved the old macro into a new header and used as as much
as possible. there are still places in the code where similar
macros are used but we would need to change the variable name
to replace them
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.
* Use task id to track old background tasks in RA procedure
* Improve robustness against RF overflow in PHY
* Increase SNR out-of-sync threshold
* Do not change frequency if it's the same
* Increase sync priority
* Increase time to start receiving to reduce input buffer occupation
* Use scoped lock in sf_worker
- 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
