I forgot to add this when making the release. Put it retroactively to
have things "in order".

Closes #828

See merge request oai/openairinterface5g!3692

Reduce throughput requirement, as this fails once two DUs are connected
to a UE, which creates more load on the machine and frequently fails
with low throughput.

CI: Enable Physim threshold check for tests on Caracal and GH

This MR adds support for configurable timing threshold files in PhySim
tests.

- Introduces a new CMake cache variable PHYSIM_CHECK_FILES to specify
  one or more timing threshold files (semicolon-separated).
- Enables optional enforcement of timing thresholds check in PhySim
  tests without changing existing test definitions.
- Defines timing thresholds for LDPC encoding/decoding in nr_ulsim,
  nr_dlsim and ldpctest on Caracal and GH machines.

SRS noise power

This MR implements the calculation of the noise power based on SRS in a
different way, and check whether SNR is more accurate or not. This MR is
built on top of the MR: !3460

A graph was added in T_Tracer to observe UL-SNR calculated using SRS.

See merge request description for measurement results.

Update Dockerfile to pass -DPHYSIM_CHECK_FILES="ThresholdsGracehopper.cmake".

Extend the timeout for physim deployments on OC to allow tests to complete
reliably.

Replace the previous add_timed_physim_test() macro with add_physim_test()
to use a single, unified function for defining physim tests. This simplifies
the test configuration and removes redundant macro definitions while keeping
all existing functionality.

This change follows up on the earlier addition of support for including
custom timing threshold files (PHYSIM_CHECK_FILES).

Update existing tests accordingly.

Introduce a new CMake variable PHYSIM_CHECK_FILES to specify CMake files
(semicolon-separated) containing timing thresholds for timed physim tests.

Add missing timinig analysis scripts to RHEL9 physim docker image. These files
are now copied from the build stage to /oai-ran/openair1/SIMULATION/tests/,
where they are expected by ctest.

Resolves following issue when running ctest in docker container:
CMake Error: Error processing file: /oai-ran/openair1/SIMULATION/tests/RunTimedTest.cmake

For some physical simulators, we have multiple SNR iterations.

The previous version of the script correctly retained only the last
measurement, but if a previous measurement condition set RC=1, the
script would fail although the final "good" run might fulfil the
measurement condition (IOW, it would show SUCCESS, but still fail on the
check).

Instead, check if all measurement lines finish on SUCCESS, which handles
the above case.

The awk script in analyze-timing.sh used syntax that works with gawk but fails
on systems where mawk is the default implementation, producing errors such as:

awk: /dev/fd/3: line 6: syntax error at or near ,
-- test command finished with SIGPIPE

Concretely, the match(text, pattern, variable) function does not exist
in mawk, as it cannot capture matches in variables. Work around by
substituing strings, and force a numeric comparison.

OC PhySim deployment: always undeploy safely

Always undeploy physim safely. See commits for more details

Fixes to prevent assertion due to 0 PRB allocation

Assertion (NPRB>0 && (NPRB + RBstart <= BWPsize)) failed!
In PRBalloc_to_locationandbandwidth0() /home/user/openairinterface5g/common/utils/nr/nr_common.c:506
Illegal NPRB/RBstart Configuration (0,51) for BWPsize 51

Probably caused by missing safeguards to prevent computing TBS with 0 PRB
as input.

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

fix RSRP computation at UE

Conflicts between !3595 (merged) and !3596 (merged) leading to double conversion
of RSRP into index in L1 and L2. With this fix it is only converted in L2.

Merge remote-tracking branch 'origin/replace-INT16_MIN-when-obvious' into integration_2025_w41 (!3472)

Replace int16 min when obvious

INT16_MIN doesn't have a opposite value on 16 bits, so SIMD abs (absolute()), or
simple C operations doesn't make the expected result.

example:
(gdb) p (short)-(short)-32768
$4 = -32768
(gdb)

This MR replaces constants INT16_MIN by -INT16_MAX (so -32767) in places where
it used for mathematical operations. This is not perfect, nevertheless reduces
overflow probability.
We saw in some places a dirty case: code do first calls to _mm_adds_epi16
(or subs), so because of the saturated operations, the probability to reach
32767 and -32768 is higher than the other numbers but, _mm_abs_epi16(), or
negate operations (conjugate) can follow, that is making strong error as
abs(-32768)=-32768

Also, don't use "set -x" debugging for oc login command:
ci-scripts/cls_cmd.py:242 sets BASH_XTRACEFD=1, which makes that all
"set -x" output is in stdout, leading to a redirect to the file into
which we redirect. This would lead to the following error with
unsuccessfull oc login:

  error: You are not a member of project "****-core-for-ci-ran".
  Error from server (Forbidden): imagestreams.image.openshift.io "oai-physim"
  is forbidden: User "system:anonymous" cannot get resource "imagestreams" in
  API group "image.openshift.io" in the namespace "****-ran"

This fixes basically two problems. First, remove "set -e", which leads
to the script exiting on error. For instance, there was the sleep which
should account for the time of the pod being in "ContainerCreating", but
might not be enough. In that case, the script would exit, leaving the
pod deployed.

Second, a fixed time is not good, as it can be too short and unduly
prolong waiting time. Replace with a loop.

- 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.

Leak trace:

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.

  Mbps)

pods deployed through helm occasionally take more time, leading to
errors such as

    Error from server (BadRequest): container "physim" in pod "oai-physims-4g-sczvl" is waiting to start: ContainerCreating

Give a bit more time before checking the logs. We cannot wait too much,
as the container will just end on FINISHED in running state, so the logs
will always be there.

The goal of this MR is to resolve memory leaks, prevent crashes, and improve code quality.

Bug Fixes:
- Fix crash in get_du_for_ue when F1 UE data doesn't exist during N2 handover
- Fix memory leaks in handover preparation and UE context cleanup
- Fix duplicate handover request handling with proper UE context validation

Code Quality Improvements:
- Prevent ASN.1 double-free bug in NGAP memory management (caller ownership
  principle)
- Fix hardcoded instance 0 bug in UE context release command
- Refactor e1_send_bearer_updates into three specialized functions with
  extracted common code
- Replace impossible ID mismatch checks with DevAssert statements
- Fix inconsistent equality checking patterns in E1AP bearer context management
- Improve error message consistency across NGAP handover functions
- Optimize PLMN identity assignment using struct copies

Documentation Enhancements:
- Improve RRC neighbor configuration documentation with actual parameter names
- Add same-machine setup guidance for N2 handover with network configuration
  notes
- Fix grammar errors and standardize naming conventions
