test now can write the NR reconfig into a PCAP for easy
debugging with Wireshark
patch also adds a new test helper to write a RRC PDU
into a PCAP file (helper packs PDCP and RLC AM first)
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.
TSAN detected wrong use of the old deque-based internal queue. To avoid
unwanted/undetected mis-use the patch uses the thread-safe block_queue
data structure instead.
we had it returning int but had a bug in using the return value properly,
i.e. handling when -1 was returned in RLC TM.
Thinking about it more, it doesn't make sense to have a negative return
value here anyway. Either the RLC can return a PDU or not. If it can't the
returned lenght is zero.
the thread workers need access to their current state to exit properly
when they are set to state STOP. However, since the state is kept in
a std::vector for all workers, it seems more appropiate to add a per-thread
running variable rather then mutexing the entire vector.
- the consumer does multi-staged waiting:
1. spins first across all queues in a RR fashion
2. each queue access is done with a try_lock.
3. if the try_lock fails, it increases the number of spins needed
2. if no queue had data, the consumer sleeps for 100 usec.
- no differentiation between queues, in terms of notification features
also make sure we don't assign LCIDs beyond the possible
number.
possible fix for https://github.com/srsran/srsRAN/issues/658
