Introduce a struct with information on FAPI structures to save resource
and data allocation into. It's in nr_mac_gNB.h because the next commits
will reuse this for all preprocessors.
Especially in pf_dl()/pf_ul(), we use a first loop using
UE_iterator(), then iterate over a subset of UEs. It has happened a
couple of times that I was using variable "UE" (from the iterator), when
it should only be used in the first UE_iterator() loop.
Rewrite UE_iterator() to effectively limit the scope of the iterator
variables to the body of the UE_iterator. This should also make it
possible to reuse multiple UE_iterator()s with the same variables in
sequence.
CI: ensure clean iperf3 server startup
- Resolves issue with iperf3 test failure in RFSim5G multiue test
- Minor fix of iperf3 test descriptions in RFSim5G pipeline
Fix for scenario with no CSI report configured for CSI-RS
After changes in !3714 (merged), if we select to measure RSRP on SSB and not
CSI-RS (default option) and there is a single antenna port (so no MIMO report
either) we won't schedule any CSI-RS measurements for the UE. In that case
ideally we shouldn't set do_CSIRS = 1 in configuration file but still the
option is possible. So the fix is to not perform any measurements at UE on
that CSI-RS but not asserting.
Closes#1015
1. Create a free_ru_session_list() function to free the memory allocated for the connected RUs
before closing the nr-softmodem.
2. xmlReadMemory() and xmlNodeGetContent() were causing serious memory leakages,
and now all is properly freed using xmlFreeDoc() and xmlFree().
This struct is used in multiple source files.
Previously, when stopping the nr-softmodem, the ru_session_list "disappears"
and the M-plane wasn't terminated properly (num_rus = 0 even though DU connected to at least one RU).
MIMO mode is defined by setting separate carriers to different antenna ports.
Benetel v1.2.2 does not support MIMO mode to be set via M-plane, and therefore
we only created one Tx and one Rx carrier.
Benetel v1.4.1 supports MIMO mode setting via M-plane.
Therefore, this commit introduces the adaptation based on the number of supported carriers by a DUT RU.
These 3 states: "oper-state", "admin-state", "availability-state" are optional,
but shall be checked in order to activate the carriers. If an O-RU doesn't support it,
we assume the expected values:
- "oper-state" = "enabled"
- "admin-state" = "unlocked"
- "availability-state" = "NORMAL"
Implement retrieval of the hardware states if O-RU supports, i.e. Benetel release v1.4.1.
Duplex is assumed to be static but for NTN bands, it is not static.
TxRX Duplex is defined in section 5.4.4 of 38.101-5 (for NTN) specs v1809
n256 190 MHz, 165 to 215 MHz
n255 -101.5 MHz, -72.5 to -130.5 MHz
n254 862 - 885 MHz
The function rx_nr_prach become autonomous, it doesn't read anymore global variables
So, it can become (later) a threadpool work, that will send a message when it finishes
rx_nr_prach_ru() still use some global variables, but it is executed in sequence, inside the ru main loop, that limits the probability of race conditions
Before starting a new iperf3 server instance in CI tests, explicitly kill any existing
iperf3 processes bound to the same port. This prevents conflicts or failures caused by
leftover iperf3 servers from previous runs that did not terminate properly or on time.
The cleanup is performed using `pkill` before launching the new server.
Handle GTP receiver errors, fix memory leaks, add CU-UP test
- Fix use-after-free bugs in GTP by properly stopping the receive thread(s)
- Fix a bug from !3519 (merged): QFI 0 is a valid QFI
- Fix multiple memory leaks in CU-UP, E1, CU-UP load tester, SCTP
- Add a (conservative) functional CU-UP test that verifies that the load tester
and CU-UP work. Test only a low throughput, as it will run in parallel with
other tests.
Use the CU-UP load tester to test the functionality of the CU-UP and
its loader tester. The requirements on this load test are intentionally
low, as it will be run with other unit tests in parallel, and should
still pass.
It uses an existing configuration file for the CU-UP. The test script
runs the CU-UP, runs the load tester, stops the CU-UP, and returns the
load tester return value as test result (which will be 0=success if all
packets have been received).
Note that this strdup has been intentioally created for debugging
purposes in core files.

Free memory including the "base pointer". Fix two places in which it was
on the stack to harmonize. The only stack variable is in reception of
new E1 messages (e1ap_handle_message()), which uses
ASN_STRUCT_FREE_CONTENTS_ONLY().

QFI 0 is a valid QFI: don't check for qfi <= 0, as uint8 cannot be
negative. Also, correctly use SDAP_MAP_RULE_EMPTY for a DRB ID (which
need to be larger than 0).
The gNB will stop the periodical logging of UEs in MAC Info level after
a configurable number of UEs have been printed, by default 8.
Set it to 17 in some CI tests to ensure we still get all UEs for the
time being, as the CI might depend on this.
