faluco fa351cd285 Rename functions that contain the unsafe word to nolock.
The term "unsafe" does not clearly state that the function is not locking the shared date and it sounds "dangerous", so use a more explicit term.

Andre Puschmann 59e1bca3f5 rlc_am_lte: fix potential crash when attempting to resize tx queue
under some circumstances it could happen that the RLC is configured
when SDUs are already being written to the queue. The resize
operation of the underlying container would fail in this case.

Make sure to empty the queue before doing the resize.

Andre Puschmann 4379c20eb9 rlc_am_lte: avoid locking of Rx mutex twice when generating status PDU
call reset_status(), which now is an private method directly when
building a status PDU. No need for the Tx side to call Rx again.
4 years ago
Andre Puschmann 53a7dc78ee rlc_am_lte: replace do_status boolean with atomic
the do_status is queried from the Tx code frequently. To reduce
chances to delay the execution because the RLC Rx side is currently
holding the mutex we can use an atomic.
