yagoda 8e0b106c22 fixing some warnings from LGTM 2020-04-27 20:59:40 +02:00
Andre Puschmann 1e0c8ead4c srsue,sync: fix TTI gap calculation and reporting 
The current TTI gap calculation assumes strict continuity
of radio time stamps, even when retuning, changing sample rate, etc.

This is certainly desireble but not necessaritly the case and may cause
issues when negative time gaps or too large gaps are detected and reported
to the stack.

this patch makes the assumption that valid TTI jumps are between 1ms
and 1s and that larger gaps are the result of screwed time-stamps
or too long radio operations.

Andre Puschmann d35c9e2b89 nas: add support ot UE test loop mode B 
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

Andre Puschmann 66a799661e gw,tft: move traffic flow template matching into own class 
this prepares the reuse of the matching functions for the TTCN3 DUT.
create own matcher class that the GW uses.

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 62e4bd9469 log_ptr: fix issue if accessing log_ptr that was reset already 
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

Andre Puschmann 94c6034339 nas: rename start_attach_request to start_attach_proc 
this is to better differentiate from "send_attach_request" that

entire attach procedure may include PLMN search, etc.

Improve robustness in RF Overflow (#1124) 
* 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
