In the UE, we wish to handle ^C in the UE to send a message before
terminating, so we allow custom wait handlers to implement such
functionality. Use itti_wait_tasks_unblock() to unblock
itti_wait_tasks_end().
Also, implement itti_wait_tasks_end() using semaphores, as signals are
not async-signal-safe (and therefore should not be used in a signal
handler).
nr_pdcp_entity_recv_sdu() processes PDCP SDUs, and forwards the PDU at the
end of the function, while having the PDCP lock. This can lead to
deadlocks, e.g., when another thread goes through RLC and tries to
access the PDCP while the PDCP tries to lock the RLC.
This commit changes the logic: instead of having recv_sdu() forward the
PDU directly, it fills a buffer with the PDU (thus the name change to
process_sdu()), and returns. We then unlock the PDCP, before forwarding
the PDU, thus eliminating potential deadlocks.
Creates function that have nr_pdcp_ prepended to their name, and change
the signature of some functions for the 5G PDCP:
- nr_pdcp_layer_init()
- nr_pdcp_data_req()
- nr_pdcp_remove_UE()
- nr_pdcp_config_set_security()
- nr_pdcp_remove_UE()
- Make separate functions for nr_pdcp_data_req_srb/drb()
Following changes are made:
1. Removed XMLs used in old pipeline lte-OAIEPC
2. Added TM1 and TM2 config, XML and YAML
3. Added pipeline details in TestBenches.md
4. Modification in Jenkins file for the pipeline
5. Added ping/iperf test cases in XML
6. Minor modification in cls_containerize.py and cls_oaicitest.py
The d array has to be cleared at the first usage, which may not necessarily
be when new_rx is true. For example, in case of DTX detected for a first
transmission, the next transmission won't have new_rx true, so d won't be
cleared, containing data from a previous transmission. Or when a LDPC
decoding is cancelled for a segment when new_rx is true, a decoding for
a retransmission will not clear d because then new_rx will not be true.
(Yes, the logic of cancellation will be changed in the future, but the
changes will be orthogonal to the ones of this commit.)
new_rx is removed.
