faluco 91677a9dcb Fix data race in sync::state, the stop() did not acquire the required lock. 2021-10-25 20:30:57 +02:00

Asynchronous NR PHY configuration (#3527) 
* Fix a race condition when accessing the NR PHY cfg by the RRC and phy workers.
Rework how the phy cfg is handled, now workers have their own copy that gets updated after a reconfig moving it out of the state class.

* Default initialize sf_len member in sf_worker for consistency.

* Asynchronous NR PHY configuration

* Fix compilation

* Corrected method override and fix unitialised value

* Added carrier equal comparison to avoid aligment byte padding comparison

Andre Puschmann 908c469f30 sync: don't fail camping on cell if current and target srate match 
this fixes #3437. The check/requirement for target srate to be different
to current srate isn't needed, and in fact fails for 6 PRBs where both are
indentical always.

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 cc2d71183e ue,phy,nr: fix race condition when setting UL grant for Msg3 
the Msg3 UL grant requires the TTI in which the RAR has been received
to calcualte the correct timing. There was a race between PHY and Stack
thread.

This patch circumvents the issue by removing a PHY state member that only holds
the RAR Rx timing. In the new interface the RA proc passes the Rx TTI
to the PHY again when setting the UL grant so the PHY can calculate the
correct timing without any state.

Andre Puschmann 6c82d63aa6 remove legacy PNF/VNF code 
the code hasn't been maintained for a while an likely needs to be
adapted for a real-world scenarios.

in order to avoid having to maintain two MAC/PHY interfaces we
remove the code from now.

Andre Puschmann 98a91a2057 sync: protect sync_state, access ue_sync object only from one thread 
races detected with TSAN, primarily the ue_sync object which isn't
thread-safe is accessed by all workers to set the CFO and by the
sync thread to receive samples (which read the CFO).

The patch introduces shadow variables that are updates from the
main thread before/after the sync is executed. The atomic shadow
variables can then be read from otherthreads without holding a
mutex, i.e. blocking the sync.
