Assign antenna ports correctly for 1 and 2 layers for aerial.
With this change aerial successfully decodes PUSCH with 2 UL layers.
The code should use sched_pusch->dmrs.num_dmrs_cdm_grps_no_data == 1 rather
than NFAPI_MODE != NFAPI_MODE_AERIAL, but that will make the changes a bit
more extensive.
Prior to this change, sending antenna_ports.val = 2 with rank 2 would tell
the UE to transmit on DMRS ports 2,3 rather than 0,1 causing it to not decode.
Optimization of PDSCH precoding operation
x86/aarch64 optimizations for precoding, more complete timing reporting in
nr_dlsim. Timing report in nr_dlsim now shows the total PDSCH generation time
and is broken down into Layer mapping, resource mapping and precoding.
The optimizations for x86 are basically reorganizing loops (for AVX512,AVX2,
NEON but not SSE2) to minimize repetitive instructions when formatting of the
precoder weights, and creation of inline functions for complex multiply-add.
AVX512 optimization was added. requiring AVX512BW. Detection of up to 4 PRBs
with common PMI for efficiency with AVX512 (was 2 in develop for AVX2).
For aarch64, native coding of the precoder to avoid inefficient SIMDe
translations for this operation.
nr_dlsim now uses default precoding indices depending on the scenario instead
of 0 which doesn't do precoding at all.
See merge request description for nr_dlsim test results.

Fix OAI UE memory leaks
Fix 1: Replaced asn1cFreeStruc with ASN_STRUCT_FREE in MAC layer to properly
free nested ASN.1 structures in cell group configuration.
Fix 2: Removed premature nullification of dedicatedNAS_Message->buf in
dlInformationTransfer processing to allow proper ASN.1 cleanup.
Fix 3: Fixed memory ownership in nr_rrc_process_dedicatedNAS_MessageList by
copying OCTET_STRING data instead of transferring ownership, preventing
ASN.1 cleanup from losing track of allocated memory
Closes#828
- Remove unnecessary NULL assignment for dedicatedNAS_Message->buf
- The original buffer is copied and transfered to NAS, so it can be properly freed by ASN.1 structure cleanup
Root cause: Code was nullifying dedicatedNAS_Message->buf pointer before ASN.1 cleanup could free the original allocation, causing the leak from OCTET_STRING_decode_uper.
AddressSanitizer leak trace (FIXED):
Direct leak of 119 byte(s) in 3 object(s) allocated from:
/#0 0x7ec2a42b4c38 in __interceptor_realloc
/#1 0x555fade852e0 in OCTET_STRING_decode_uper
/#9 0x555fadb48b11 in nr_rrc_ue_decode_dcch.
The leak was caused by improper memory ownership handling in the
dedicatedNAS_MessageList processing. The function was transferring
buffer ownership to NAS messages and then preventing ASN.1 cleanup
from freeing the original allocations by setting
list.count = 0, causing a memory leak.

Fix:
- Copy OCTET_STRING data instead of transferring ownership
- Allow ASN.1 cleanup to properly free original allocations
This fixes the leak that occurred during rrcReconfiguration
message processing when dedicatedNAS_MessageList was present.
Closes#828
- Replace asn1cFreeStruc with ASN_STRUCT_FREE in MAC layer cleanup
- Fixes improper memory management of NR_CellGroupConfig structures
Root cause: asn1cFreeStruc only calls ASN_STRUCT_RESET + free(), which doesn't properly free nested ASN.1 allocations. ASN_STRUCT_FREE frees all nested structures completely.

Make all targets compile
This MR enables us to compile all targets, and does that in one CI test. This
closes#726. Now, this should work:
cd ~/openairinterface5g
mkdir build && cd build
cmake .. -GNinja && ninja
To achieve this, I did the following:
- some targets have been fixed (warnings, errors)
- some targets have been removed when they did not seem to serve a good purpose
(e.g., an almost empty test)
- some targets have been commented (e.g., LTE simulators, some unitary tests)
which we maybe want to revive in the future
- some targets built when just building with ninja, but not all. For instance,
telnetsrv_enb would typically build, but it was missing a dependency. Doing
cmake .. -GNinja && ninja telnetsrv_enb would show this (in develop)
To help with the last bullet point, there is a script compile_targets.sh that
can compile targets independently (and in parallel, to not wait for ages) to
show that targets compile properly compile-targets.patch.
In almost all cases, the problem is that a specific module uses the logging
module, which depends on T, which needs to dynamically create headers. The way
to do this is to have a dependency, and many targets use generate_T or {T_LIB}
({} intentional: T might be absent, so then it evaluates to nothing). However,
not all do this, and those that depend on T actually don't depend on T, but on
the logging module, which in turn depends on T. So in many places, a simple
dependency onto log_headers fixes this problem, and generate_T or {T_LIB}
simplifies the dependency (but not always). The commits should have more info.
Note that at least the targets in FlexRIC do not all compile, at least in the
configuration that we use in docker/Dockerfile.build.ubuntu. So for the latter,
we cannot build with a simple ninja, but FlexRIC seems to be the only one that
does not compile. Since FlexRIC is a separate repository, that needs to be
addressed in the corresponding repository.
Split monolithic e1_send_bearer_updates into three focused functions:
- e1_send_bearer_updates(): DRB setup from F1 UE Context Modification Response
- e1_request_pdcp_status(): Request PDCP status during inter-CU handover

- append_e1_drb_mod_req(): Common DRB-to-mod for bearer request logic
- e1_send_bearer_modification_request(): Common sending step
Bug fixes:
- Fix loop bounds (i < n instead of i == n)
- Fix array access bounds checking
- Fix DRB ID consistency
Memory management:

Root cause: Handover context allocated in N2 handover source gNB trigger path (nr_rrc_trigger_n2_ho)
for any successful N2 handover but not properly freed in all handover completion scenarios.
The UE context release complete handler was missing cleanup for handover context.
Solution: refactor handover context cleanup
- Move nr_rrc_finalize_ho() call to rrc_delete_ue_data() for centralized cleanup
- Remove redundant nr_rrc_finalize_ho() calls from handover failure paths:
* rrc_CU_process_ue_context_release_request() - UE not deleted yet
* invalidate_du_connections() - UE will be deleted later
- Keep nr_rrc_finalize_ho() calls in handover success paths where UE continues operating
- Ensures handover context is cleaned up exactly once when UE is actually deleted
- Prevents potential double-free and use-after-free issues in handover cleanup
This centralizes all UE data cleanup in rrc_delete_ue_data() and ensures
handover context is properly managed throughout the UE lifecycle and cleaned up
when UE delete happens.

get_nr_mtc() but never freed it after creating the measurement gap configuration.
The create_measgap_config function only reads from the structure and doesn't take

- Replace heap allocation with stack allocation for seq_arr_t structures
- Use proper seq_arr_free() with free functions for ASN.1 structures
- Remove unnecessary malloc/free calls for sequence containers

- Add early check for existing UE context by AMF UE NGAP ID at beginning of rrc_gNB_process_Handover_Request
- Add dedicated function to get UE context by AMF UE NGAP ID: rrc_gNB_get_ue_context_by_amf_ue_ngap_id()
- Send handover failure with appropriate cause if UE context already exists
- Remove redundant ho_context NULL check that could never be true for newly created UE contexts
- Prevents duplicate handover processing and resource leaks
Add check for cu_exists_f1_ue_data() before calling cu_get_f1_ue_data()
to prevent assertion failure when telnet command 'ci fetch_du_by_ue_id'
is used for UEs that have been handed over via N2 (and no longer have
F1 UE data).
This fixes the crash:
Assertion (ret == HASH_TABLE_OK && data != ((void *)0)) failed!
In get_hashtable_data() /oai-ran/openair2/F1AP/f1ap_ids.c:36
element for ue_id 1 not found
The function now returns NULL gracefully when F1 UE data is not available.

- Add proper cleanup of allocated ASN.1 structures in all return paths
- Fix early returns that were leaking NR_HandoverPreparationInformation
- Fix early returns that were leaking NR_RRCReconfiguration
- Add cleanup at end of successful function execution
This prevents memory leaks when processing handover preparation information
during N2 handover procedures.
- Add UE context cleanup before sending handover failure message
- Prevents memory/resource leak when PDU session establishment fails during handover
- UE context was created but never cleaned up on failure path
This fixes a bug where UE contexts would accumulate over time
when handovers failed after context creation.
BWP with no PRACH occasions
This MR includes fixes at gNB and UE in case the current BWP has no PRACH
occasions, i.e. we need to switch to initial BWP.
These libraries depend on the logging module, so add the right
dependency log_headers. Indirectly, this will fulfill the condition of
T. I consider the prior usage of generate_T or {T_LIB} incorrect,
because basically none of these libraries actually, actively use T, but
rather only the logging module, which pulls in T. The dependency of
log_headers will also take care of generating and including T headers,
which is a dependency of the logging module.
For conf2uedata and related, fulfill the dependency
through conf2uedata_lib (on which the rest depends).
Since E2 agent uses the config library, include it directly. This also
makes the dependency on T obsolete, because
- it is the logging headers that are needed, and
- the T dependency is fulfilled through the log_headers.
XNAP is asn1c compiled with -no-gen-BER. Correspondingly, no
ber_decoder.h file is created. However, when running cmake followed by
ninja, it notices the absence of this file:
ninja explain: output openair2/XNAP/MESSAGES/ber_decoder.h doesn't exist
which triggers a complete rebuild of XNAP ASN.1. Without this file, the
targets are not marked as dirty.
Remove, because
1) it does not compile (the asn1c generated code should be prepend with
LTE_ etc, nobody did that)
2) a shared module makes no sense
3) the configuration is trivial to recreate
- Fixed incorrect log messages that said 'PCI=%lu' when printing nr_cell_id
- Now prints both NR Cell ID and PCI when DU is found
- Provides better debugging information for handover requests
- Add _E1_EQ_CHECK_OPTIONAL_PTR checks for pdcp_config, sdap_config, UP_TL_information, and securityIndication
- Fix bug in eq_pdu_session_to_mod_item where a->UP_TL_information was compared with itself instead of b->UP_TL_information
- Fix eq_security_ind call to properly handle return value with early return pattern
- Improve consistency with existing macro usage patterns in the codebase
- Provide better error reporting for optional pointer field mismatches
Replace result &= pattern with consistent early return pattern:
- Fix mixing of logical (&&) and binary (&) operators
- Use consistent 'if (!eq_()) return false;' pattern throughout
- Fix bug in eq_bearer_context_mod_response where drbModA was compared with itself
- Remove unused 'bool result = true;' variables
- Always return true at the end of equality functions
This makes the code more consistent with the rest of the codebase
and provides better error reporting through the existing _E1_EQ_CHECK macros.
Improvements to RRC PDU session and DRB handling logic
This merge request introduces a major simplification and cleanup of the gNB RRC
PDU Sessions and DRBs handling logic. The core goals of this work are to:
- Replace fixed-size PDU Session, DRBs and QoS arrays with dynamic containers
- Simplify and modularize helper functions for session/DRB management
- Prepare for further refactoring of the PDU Session state machine
- Improve code safety and maintainability through better bounds checking
- Replace simple counter-based DRB ID assignment with actual DRB ID lookup
- Add nested loop to iterate through DRBs for each PDU session to be release
- Improve logic flow with early continue for non-matching PDU sessions
This ensures DRB release list contains correct DRB IDs that correspond to actual DRB entities
* There is no IE corresponding to PDU sessions failed to release
in the PDU SESSION RESOURCE RELEASE RESPONSE message. This was removed
and the corresponding code was refactored and cleaned up.
* In the Release Command handler, only established PDU Session are set to be
released. The Response message is filled accordingly.
Motivation:
The previous architecture had several issues:
- Duplicate DRB generation logic in generateDRB() and generateDRB_ASN1()
- Embedded SDAP/PDCP configs in drb_t created tight coupling
- No clear separation between RRC internal state and ASN.1 encoding
- Maintenance burden due to duplicated configuration logic
New Architecture:
- drb_t now only stores DRB-specific data (ID, PDU session ID, PDCP config)
- SDAP configuration moved to PDU session level (following PDCP design pattern)
- ASN.1 encoding helpers (nr_rrc_build_*_config_ie()) handle conversion
- Single source of truth for DRB creation in RRC via nr_rrc_add_drb()
Key changes:
- Store nr_sdap_configuration_t per PDU session
- Simplified drb_t structure: removed embedded SDAP/PDCP configs, added pdusession_id
- New helper: nr_rrc_build_sdap_config_ie()
- Updated createDRBlist() to use new helper functions and proper DRB ID lookup
- Refactored trigger_bearer_setup() to use nr_rrc_add_drb() and fill_e1_drb_to_setup()
- Removed generateDRB() and generateDRB_ASN1() functions
- Updated set_bearer_context_pdcp_config() to return config by value
- Added SDAP configuration header file for type definitions
This eliminates code duplication, improves maintainability, and creates
a cleaner separation between RRC state management and ASN.1 encoding.
- Move QoS-related enums and structures from ngap_messages_types.h to 5g_platform_types.h
- Replace ngap_* QoS types with generic qos_* types for better reusability
- Update field names from allocation_retention_priority to arp for consistency
- Update all references across RRC and NGAP modules to use new type names
- Remove duplicate QoS type definitions from NGAP-specific header
This improves code organization by centralizing QoS parameter definitions
in a common platform types header and eliminates NGAP-specific naming
in favor of more generic, reusable type definitions.
