Robert Schmidt adb02aa2ee Merge remote-tracking branch 'origin/bugfix-release-usrp' into integration_2022_wk06 2023-02-09 19:23:04 +01:00
Cedric Roux 344f8b75e6 bugfix: try to handle USRP devices correctly to avoid crashes 
Some problems when we release the device:

    - Calling the destructors is wrong, we should set the pointers to NULL.
      These are shared pointers, this is C++.
    - We have to stop rx by doing a STREAM_MODE_STOP_CONTINUOUS.
    - The end-of-burst for tx has been simplified.

This problem when we acquire the device:

    - Calling get_rx_stream() many times seems to be problematic.

We now should have a better behavior with UHD 4.2 and N310. (Hopefully with
others too.) No crash seen so far.

Cedric Roux fc7bcceca9 fix a small bug and add a log for when recvfrom() fails 
recvfrom() returns ssize_t, not size_t.

Cedric Roux 924d88bbf9 bugfix: avoid a crash when oai_exit is set 
There was a crash when we exit the nr softmodem with AW2S device.
The array rxbase[] was surely freed() by some other thread, so
let's not access it after detecting oai_exit != 0.

We also need to unblock a possible reader thread. The chosen way to
do may be not the best. To be checked.

Robert Schmidt 805dbe7272 Lower RFsim timeout when no UE connected 
This will lead to quicker drop of the UE context in the gNB once it
disconnected from RFsim.
