Add missing packing for CONFIG.request parameter BetaPSS
Adds the packing procedure for the parameter BetaPSS, as well as adding this
parameter to the utility functions where it is missing
IPV6 support for telnet socket binding
Now, the listening telnet socket is only bound to the dedicated interface IPs in
config file, both for V4 and V6

Fix handling of IPv4v6 PDU sessions
The code previously checked that the supplied PDU sessions's type is
exactly what we requested. However, at least OAI 5GC will only give us
an IPv4 PDU session if we request IPv4v6 (so the check would fail).
Extend the validation to either check exact match, or, if IPv4v6
requested, that it is either IPv4 or IPv6.
Fix error
openair1/SIMULATION/NR_PHY/dlsim.c:1057:37: runtime error: member access within misaligned address 0x7f8a67e01010 for type 'struct NR_Sched_Rsp_t', which requires 32 byte alignment
Prior to this commit, constants NB_ANTENNAS_RX/TX are provided on the
command line to each compiler invocation. This has the drawback (1) that
also files that don't need that get the constants, and (2) it is not
easy to find them using ctags or similar, as the only definition is in
CMakeLists.txt (where it is not found).
In this commit, use cmake configure_file() to write a header file with
these constants. The file will be generated during cmake invocation, and
written to <build-dir>/common/cmake_defs.h. The relevant files that
need this definition will pick it from the header.
This has been used previously also in a commit to write git information.

Ensure the CU-CP only sets up PDU sessions that are not already
established for the UE, skipping duplicates while keeping the NG UE
context valid. This aligns with 3GPP TS 38.413 PDU Session setup
semantics for duplicate session IDs
Changes:
- Change rrc_gNB_process_NGAP_INITIAL_CONTEXT_SETUP_REQ to scan requested
PDU sessions and detect IDs that already exist in UE->pduSessions with
PDU_SESSION_STATUS_ESTABLISHED
- Log a warning and skip already established PDU session IDs so they are
not added to UE->initial_pdus
- Collect only non-established PDU sessions into a temporary stack array,
allocate UE->initial_pdus with the exact count, copy them in, update
UE->n_initial_pdu, and only refresh UE AMBR when there is at least one
session to set up
Since the grand-parent commit, if possible, the gNBs synchronize on a
slot-level boundary. Some configuration files/command line overrides
left the same SSB position for two DUs in RFsim-based handover
scenarios, which then makes that the UE cannot decode the SSB.
This commit changes the positions such that this is possible again. In
the F1 HO docker-compose
(ci-scripts/yaml_files/5g_f1_rfsimulator/docker-compose.yaml), we set it
to 2 to send only one SSB (not 2 with bitmap 3).
Ensure DRBs from multiple PDU sessions are appended into the F1 DRB array
without overwriting previously filled entries.
Update fill_drb_to_be_setup_from_e1_resp to call fill_f1_drbs_from_e1
with &drbs[nb_drb] so each PDU session’s DRBs are written after the
current count
fix: removed the nssai_sd parameter in the ue.conf file
Following the tutorial in the RF simulator, the PDU session cannot
be established because the Slice Differentiator to request(nssai_sd)
parameter in the ue.conf file is 1(integer) but in the documentation
the default value of the nssai_sd is 0xFFFFF(meaning "no SD")
Now the nssai_sd parameter is removed in the ue.conf to establish the
PDU session.
NR UE: correctly compute writeTimestamp for SCS > 30 kHz with rf-simulator
Contains also two minor cleanups for nr-ue.c:
- make fp point to constant NR_DL_FRAME_PARMS where possible
- use c16_t type for I/Q sample arrays

NR UE: fix PRACH k1 calculation at MAC when handover
The k1 for PRACH calculation in config_common_ue() should be the same as in
config_common_ue_sa(), otherwise k1 is wrong when handover to target cell if
msg1-FDM not 0 in reconfigurationWithSync.
Verified with 3rd-party gNB.
The code previously checked that the supplied PDU sessions's type is
exactly what we requested. However, at least OAI 5GC will only give us
an IPv4 PDU session if we request IPv4v6 (so the check would fail).
Extend the validation to either check exact match, or, if IPv4v6
requested, that it is either IPv4 or IPv6.
Similarly to gNB, eNB, lteUE, end with a "Bye." that the CI (will) check
for.
The right way to do this would be to use the exit code, but most
executables do not actually end with 0, such that we need to check for
this. Thus, this commit is only to harmonize with other executables.
Following the tutorial in the RF simulator, the PDU session cannot
be established because the Slice Differentiator to request(nssai_sd)
parameter in the ue.conf file is 1(integer) but in the documentation
the default value of the nssai_sd is 0xFFFFF(meaning "no SD")
Now the nssai_sd parameter is removed in the ue.conf to establish the
PDU session.
This commit integrates the CUDA-based channel simulation pipeline into
the nr_dlsim.
A new `--cuda` command-line flag is added to enable the GPU path at
runtime. When activated, the simulator will:
- Allocate all necessary GPU and pinned host memory via the new
`init_cuda_chsim_buffers` helper function.
- In the main simulation loop, call the `run_channel_pipeline_cuda`
function to perform the channel simulation on the GPU, bypassing the
CPU-based functions.
- Clean up all CUDA resources on exit using the
`free_cuda_chsim_buffers` helper.
Additionally, dlsim is now using the float version of channel_multipath and add_noise functions.
Also, The input data is formatted as interleaved IQ, with separate antennas to ensure a fair comparison with the GPU operation.
gNB: Reset NDI only after usage in case of disable HARQ
Solves this warnings seen in the UE trace:
NDI indicates re-transmission but computed TBS 3968 doesn't match with what previously stored 3368
Issue happens only if feature disable_harq is enabled. GNB resets the harq
process (including NDI) as PUCCH will not be sent for this harq process, but
before the harq process is used in DCI payload preparation.
Fix is to reset the harq process after harq process in case of no PUCCH.
Fail early if configuration module can not initialize properly
In the case that the config module cannot load the driver for libconfig or yaml,
currently, there might be a cascade of errors that are difficult for users to
understand. For instance (partially redacted for clarity):
[CONFIG] Error calling dlopen(libparams_libconfig.so): libparams_libconfig.so: cannot open shared object file: No such file or directory
[CONFIG] config module "libconfig" couldn't be loaded
[CONFIG] config_get, section log_config skipped, config module not properly initialized
[LOG] init aborted, configuration couldn't be performed
[CONFIG] config_get, section (null) skipped, config module not properly initialized
[CONFIG] /home/francesco/openairinterface5g/common/config/config_userapi.c 68 nfapi has no processed integer availablle
[CONFIG] config_get, section (null) skipped, config module not properly initialized
Assertion (get_softmodem_params()->default_pdu_session_id == -1) failed!
In get_common_options() /home/francesco/openairinterface5g/executables/softmodem-common.c:161
Use uicc0.pdu_sessions.[0].id to change the requested PDU session ID (is 0)
Here, the error is the missing shared object, but a user is more likely to look
at the last error instead of the first.
This commit addresses it by checking early for CONFIG_ISFLAGSET(CONFIG_ABORT),
and stopping if it is set. Additionally changes include making functions static,
removing late CONFIG_ISFLAGSET() checks, and the CONFIG_ISFLAGSET() in
load_configmodule(), because at that time "uniqCfg" is not set yet and thus does
not do anything (this is likely a regression of an earlier cleanup).

Currently, we derive frame and slot number based on `proc->timestamp_rx`
using
`proc->frame_rx = (proc->timestamp_rx / (fp->samples_per_subframe*10))&1023;` and
`proc->tti_rx = get_slot_from_timestamp(proc->timestamp_rx, fp);`
This ignores the samples `proc->timestamp_rx % fp->samples_per_frame`
while computing the frame and slot number creating a mis-alignment with the slot boundaries.
We fix this alignment by compensating these samples during the first reception.
