Andre Puschmann 28668aac34 ue,proc_ra_nr: add temporary flag to skip RAR reception 
this will be removed again as soon as the eNB supports full RAR
transmission.

Andre Puschmann d78cbdf9bb ue,proc_ra_nr: fix retransmission of PRACH after failed RAR rx

a timer but tx new preamble directly

Andre Puschmann 99dc94ab38 nas: make state variables atomics 
NAS states and substates maybe be requested from other threads so
they need to be protected.

Note that the caller still needs to hold it's own mutex if different
actions are required based on the 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 5999b0d3a5 ue: move blocking wait for detach outside of stack class 
the thread sleep waiting for the UE release should not run
on the stack thread. Move it to the UE class therefore.
 2021-07-02 17:22:49 +02:00
Andre Puschmann 3173dedf0a ue_stack_lte: make sure to execute stack commands on Stack thread 
some commands were executed from the calling thread which may lead
to concurrent access to members. Detected by TSAN. The patch
moves all remaining calls (the majority was alread moved) to the
Stack task queue.

Andre Puschmann fb4dd3ba7b ttcn3: fix various races between SS and Stack thread detected by TSAN 
fixed through the right usage of mutexes in both TTCN PHY and syssim.
nested mutex locking is solved by calling SS from the PHY after
releaseing the PHY lock again.

Andre Puschmann 0a16f48869 gw: fix race condition 
GW thread was checking the default_eps_bearer variable without
protection. RRC could update it when deleting DRB or receiving RRC
connection release.

Andre Puschmann 4d11e5552a rrc,ue: for RRC conn release, delay transition to RRC idle by 60ms as per TS 36.331 
when receiving RRC connection release all actions shall be delayed by 60ms as
per the standard

Andre Puschmann 368c7b9e4f ue,stack: clear all EPS bearers when going RRC idle
