fix IP address in 4G UE
The following error was appearing when running LTE UE:
inet_pton(): cannot convert -64.-74.0.2 to IPv4 network address
The allocated address by the core actually is 192.182.0.2.
On my host "char" is signed, leading to the above error (192 and 182
are seen as signed).
Let's force "ip_addr" unsigned and everyone is happy.
Correct block_length to Kprime for LDPC decoder
When compile the OAI by CMake, it shows the following error:
../openair1/PHY/CODING/nrLDPC_decoder/nrLDPC_decoder_CL.c:353:40: error: no member named 'block_length' in 'struct nrLDPC_dec_params'
int block_length = p_decParams->block_length;
NR UE: consider the ratio of PUSCH EPRE to DMRS EPRE when calculating PUSCH
DMRS power scaling
When calculating DMRS scaling ratio, we should consider PUSCH EPRE to DMRS
EPRE according to TS 38.214 Table 6.2.2-1.

Enable SSB-SINR based CSI reporting
3GPP 38.331 release 16 specifies that If the field reportQuantity-r16 is present,
UE shall ignore reportQuantity (without suffix). reportQuantity-r16 configures
SSB based SINR as the reporting quantity.
set do_SINR = 1; in gNB params part of the config file to enable SSB based SINR
reporting.
Cleanup and refactor initial gNB configuration
This is follow-up on !3048 (merged). Major changes in this MR:
- Add config functions to reduce redundant code repeated in multiple places in the file
- Add macros to reduce redundant code in gNB configuration
- Refactor RCconfig_NR_NG
- Cleanup obsolete and commented out code
- Refactor includes in executables/nr-gnb.c
- Introduce platform type plmn_id_t for consistency across the stack: F1AP, NGAP can now use the same struct type
- And other minor formatting
Create nrUE network interface from SDAP (rebased)
A rebase of !2485. Dropped a few refactors and SDAP manager changes.
Changes
1. Move tunnel interface read thread to SDAP for gNB (noS1) and UE (noS1 and SA).
2. Hold tunnel interface socket fd in SDAP entity instead of global variable.
3. Handle UE tunnel interface creation and IP configuration from NAS thread in noS1 and SA modes.
4. Modified UE tunnel interface naming scheme. Additional PDU sessions get oaitun_ue<id>p<pdusession_id>.

This commit refactors the TUN interface management by moving its creation
and configuration from the PDCP layer to the SDAP layer for UE.
Key changes include:
- Introduced `tun_generate_ue_ifname` and `tun_destroy` functions for better
TUN interface lifecycle management.
- Added support for creating and destroying UE-specific TUN interfaces in SDAP.
- Refactored `nr_pdcp_module_init` to remove TUN-related logic and moved it
to SDAP.
- Updated NAS and SDAP layers to handle PDU session-specific TUN interface
creation and configuration.
- Enhanced SDAP entity management to include TUN socket handling and thread
lifecycle.
- Updated NAS message handling to initialize default PDU session TUN
interfaces in NOS1 mode.
- Use a single SDAP thread function for gNB and UE
- Allow noS1 mode also in SA on gNB
These changes improve modularity by isolating TUN interface management within
the SDAP layer, aligning with the 3GPP architecture, and simplifying the PDCP
layer.

This test verifies that a NAS Registration Accept message, as received
from the OAI CN5G, is correctly decoded and matches the expected output
structure. It ensures that future changes to the NAS decoder do not
break compatibility or correctness with existing decoding behavior.
The SD stored in the allowed S-NSSAI list was hardcoded in the decoding
function, however this IE is not mandatory but optional, therefore
the check of the decoded message contents should take into account
this and check the stored value against the one from the UICC only when the field is present.
If no SD was received, consider the UICC SD a valid one.
Also, add free function to Registration Accept library and adopt in stack to free NAS
Registration Accept after use: heap memory is allocated for this message during decoding
and shall be free after processing.
3GPP 38.331 release 16 specifies that If the field reportQuantity-r16 is present, UE shall ignore reportQuantity (without suffix).
reportQuantity-r16 configures SSB based SINR as the reporting quantity.
set do_SINR = 1; in gNB params part of the config file to enable SSB based SINR reporting instead of the default RSRP based.
Replaced `sprintf` with `snprintf` in gnb_config.c to enhance memory safety
by preventing potential buffer overflows. `sprintf` can cause buffer overflows
by not checking the destination buffer size. In contrast, `snprintf` allows
specifying a maximum buffer size, ensuring no overflow occurs by limiting
the number of characters written, including the null terminator.
Integration: `2025.w15`

CI: Replacing Devkit server with a Grace Hopper in Aerial pipeline
Switch servers on the Aerial pipeline from Gigabyte (AMD) to Grace
Hopper (ARM), and make the necessary changes:
- Update XML, YAML, and gnb.conf
- Change the argument passed to the L1 in aerial_l1_entrypoint.sh to be
compatible with the GH
- Update the Aerial setup in TESTBench.md and Aerial_FAPI_Split_Tutorial.md docs
- Decrease the tested throughput due to an issue with the RU. Will open
another MR to increase it once the problem is fixed.
