Make number of UL/DL actors in NR UE fully configurable
Due to different processing requirements on different CPUs it might be
beneficial to enable the users to set the number of UL/DL actors.
Allow disabling UL/DL actor frameworks and processing inline or setting
the number of DL/UL threads with --num-ul-actors/num-dl-actors
This was tested to work with 0 UL/DL actors with rfsim.

Add CI test to force RRC IDLE and new connection setup with 5G-S-TMSI
This MR is a follow up to !2725 (merged)..
The primary goal is to introduce a CI test that enforces the following behavior:
- Forces the UE to enter RRC_IDLE state.
- Validates the UE's re-connection procedure using the 5G-S-TMSI as the UE
identity.
fix the number of preambles per SSB at UE in case PRACH is configured with groupB

Replace hashtable with epoll_event_t in rfsimulator
Replace the FD <-> buffer_t hashtable with epoll_event_t mapping. This
simplifies the code, reduces the probability of memory leaks, and removes
a possible data race on the hashtable during rfsimulator shutdown.

The UE shall use the currently stored UL NAS count to derive the

to be done it should be explicitly done elsewhere.
Closes#832
The Security Mode Command is the only NAS message sending a security header
type "integrity protected with new 5G NAS security context". Such header
type is indicating that there is no valid security context and it is
indicating the current one configured by the AMF.
When receiving a Security Mode Command the "AMF shall reset the downlink NAS COUNT"
and use it to integrity protect the initial Security Mode Command. "The AMF shall
send the SECURITY MODE COMMAND message unciphered, but shall integrity protect [...]
The AMF shall set the security header type of the message to
"integrity protected with new 5G NAS security context".
See 5.4.2.2 3GPP TS 24.501.
This commit is ensuring the NAS DL count is reset when the relevant security header
is received. Also, the security container is deleted since no more valid and
NAS_SECURITY_NO_SECURITY_CONTEXT is returned. The setup of the new security context
is done by "handle_security_mode_command",
NAS 3GPP TS 24.501 clause 4.4.4.2 specify which NAS messages
are an exception to the integrity protection. All the other
scenarios are expected to be integrity protected. The
nas_security_rx_process function is returning:
1) NAS_SECURITY_NO_SECURITY_CONTEXT if no security context is established
2) NAS_SECURITY_UNPROTECTED for the messages listed in 4.4.4.2
3) NAS_SECURITY_INTEGRITY_PASSED if the integrity check is successful
These 3 results can be all considered successful. The other not.
Also, add a function to check whether a message is allowed to be
integrity unprotected, as per clause 4.2.2.2.
* trigger Identity Response callback from the handler
* process decoded message
According to 4.4.4.2 3GPP TS 24.501, Identity Request
with Identity Type SUCI is not expected to be
integrity protected.
The information about the payload carried by NAS DOWNLINK is helpful
in the logging and also for debugging purposes, therefore it was
added in this commit by enabling the already existing relevant function.
This commit restores the behaviour before the changes introduced in 611c0554. The NAS
Deregistration Accept message is unprotected, therefore the function will return
NAS_SECURITY_UNPROTECTED that would then be considered as NAS_SECURITY_INTEGRITY_PASSED
Unprotected message have a plain header of 3 octets, however security protected messages
have a 7 octets header.

CI: revert modification of SSB per RACH occasion in SC-FDMA test
This MR reverts the parameter ssb_perRACH_OccasionAndCB_PreamblesPerSSB_PR back
to 4, undoing the change introduced in commit a4f9a7a6. The initial modification
was made as a potential fix for a reestablishment failure observed in the SC-FDMA
test case of the SABOX-B200 pipeline. However, further validation has shown that
this parameter was not the root cause of the issue.
T: macpdu2wireshark: dump to file instead of sending UDP packets
In NR with several layers, we may have MAC PDU of size bigger than 64KB,
which does not fit into a UDP buffer, destroying macpdu2wireshark.
Let's add an option to dump to a pcap file instead of using UDP packets.
The DLT 252 magic is used (check wireshark documentation to understand).
Run macpdu2wireshark with -h to see how to configure wireshark to read
the produced files.
several fixes and cleanup for nrLDPC_coding_t2
Newer DPDK driver versions may directly provide the internal HW mbuf in the
dequeued structure. So don't try to free the mbufs from that dequeued structure,
but the ones we allocated. Also, this mbuf has an offset to its output data, we
must consider this when accessing the output data.
Main contents of this MR:
- support newer DPDK versions
- make sure to free allocated mbufs
- fix q_bufs memory leak
- use rte_pktmbuf_mtod_offset() to consider offset when accessing output data
- convert the correct number of LLRs from 16 Bit to 8 Bit
- remove unused variables and functions
- some more code cleanup

Add physim tests into ctest framework
Convert physim testcases listed in
cmake_targets/autotests/test_case_list.xml into ctest. Note: Tests for
dlsim_tm4 are excluded, due to compilation issues.
CTest evaluates success based on return code: '0' = pass, non-zero =
fail. For some simulators, the return code is non-zero even when the
test is successful (as indicated by success messages in the test logs).
For some simulators, the return code is always '0'. This inconsistency
has been address in the first two commits of this MR.
To build and execute these tests:
- using cmake
cd openairinterface5g
mkdir build && cd build # you can also do that in cmake_targets/ran_build/build
cmake .. -GNinja -DENABLE_PHYSIM_TESTS=ON && ninja tests
ctest
- using build_oai: physim-related ctests are activated when PHY
simulators are built (use build_oai with '-P' or '--phy_simulators'
option)
cd openairinterface5g/cmake_targets
./build_oai --ninja --phy_simulators
cd ran_build/build
ctest
Link to newly created 4g and 5g RAN-Physim-Cluster pipelines:

- RAN-Physim-Cluster-5G: https://jenkins-oai.eurecom.fr/job/RAN-Physim-Cluster-5G/
Initially we were testing SNR from -3 to 7 dB, in recent runs PUCCH test
succeeds at SNR = 0 or 1 dB. Starting at higher SNR helps to reduce test
runtime. Set maximum SNR to 7dB, as it was done in the initial test scenario,
to ensure that possible performance degradation is detected.
The cls_physim1.py is no longer needed. Function for physim deployment has
been migrated to the Cluster class. Log analysis functionality has been
moved to the Analysis class.
Set the CMAKE_RUNTIME_OUTPUT_DIRECTORY CMake option during the OAI build
to control the location of runtime target files. This ensures that ctest
can locate necessary executables after they are copied to the target
Docker image.
Convert physim testcases defined in cmake_targets/autotests/test_case_list.xml
into CTest based tests. These test are activated when '-DENABLE_PHYSIM_TESTS=ON'
CMake flag is set.
Note: Tests for dlsim_tm4 are excluded, due to compilation issues.
CTest evaluates success based on return code: '0' = pass, non-zero = fail.
The following table outlines the physim executables, their success expressions
(`expr_true`), and the return codes for success (`ret_success`) and failure
(`ret_fail`). The `expr_true` is used in test_case_list.xml to check for test
results.
| test_exec | expr_true | ret_succ | ret_fail |
| ------------- | -------------- | --------------- | ----------------- |
| dlsim | passed | 0 | -1 |
| ulsim | passed | 0 (ret) | 1 (ret) |
| ldpctest | BLER 0.000000 | 0 | 1 |
| polartest | BLER= 0.000000 | 0 | 1 |
| nr_pbchsim | PBCH test OK | 0 | 1 |
| nr_dlsim | PDSCH test OK | 0 | 1 |
| smallblocktest| BLER= 0.000000 | 0 | 1 |
| nr_ulschsim | PUSCH test OK | 0 (n_errors) | n_errors |
| nr_pucchsim | PUCCH test OK | 0 | 1 |
| nr_ulsim | PUSCH test OK | 0 (ret) | -1 (ret) |
| nr_prachsim | PRACH test OK | 0 (prach_errors)| > 0 (prach_errors)|
| nr_psbchsim | PSBCH test OK | 0 (errors) | > 0 (errors) |
Add CMake flag "ENABLE_PHYSIM_TESTS=ON" when building OAI with "-P"
or "--phy_simulators" option. This allows physim-related ctest to
be executed from build directory.
Add dependency on coding lib for all 4G physims
Setting the DEBUG_UE_TIMING flag caused a flood of UE timing logs, resulting
in dlsim output logs as large as 1.5MB per test in CI. This commit comments
out the line where we set the flag to reduce log verbosity.
- Change return value of nr_dlsim, nr_pbchsim and nr_pucchsim to:
- Return '0' if test succeeds (indicated also by "PDSCH/PBCH/PUCCH test
OK" in the test log).
- Return '1' if test fails.
- Updated polartest, smallblocktest, and ldpctest to check BLER and return
appropriate status:
- Returns '0' if BLER equals 0.000000 (indicating success).
- Returns '1' for all other BLER values (indicating failure).
- This change improves consistency in return values across the test physims.

Improvements for LDPC encoding
AVX512 modifications for LDPC encoding: interleaving, ZC384 BG1, output
formatting for encoder, segmentation (memcpy instead of loop). some
improvement in TX for aarch64 in same places where AVX512 support was
added. Also, rate matching and interleaving are done on bytes containing
8 segments and reformatting of the output is done at the end of segment
processing instead of after ldpc encoding.
This improves the overall performance of the NR DL transmitter in gNB
See the merge request description for numbers.
Release all SDAP entities for a UE in nr_rrc_going_to_IDLE().

This implementation requires GFNI and AVX512VL support on the target machine.
1. The encoder writes the output in sequence after the encoding tasks completed instead of writing within the tasks.
2. Simplify the output writing to make it more readable.
Co-authored-by: Laurent Thomas <laurent.thomas@open-cells.com>
There was a risk of a race condition between encoding tasks on the output array.
It could be that two task compete in writing a word at the border of their respective segment groups.
This commit offers to solve this issue by retaining the tail word in a struct that is returned after task completion so that segment group border can be fixed after completion of all the tasks.
Comes with additional cleanups of nrLDPC_coding_segment_encoder:
1. Move the section of code dedicated to writing to the encoding library output to a separate function.
2. Remove bit interleave debug in AVX512VBMI case of output writing for improving code readability.
1. nrLDPC_coding_segment_encoding: Clarifying encoder parameters
The way the encoder implementation params was used could be made clearer:
* `macro_num` was always used in order to calculate segment indexes.
It is clearer to pass directly the first segment index.
* The initialisation of a common implementation parameters structure can be made clearer.
2. nrLDPC_coding_segment_encoder: Remove multi segment dimension in encoder output
The output of `LDPCencoder` was a 2D unsigned char array.
But all the segments were actually packed in the first segment, 8 bits of different segments per byte of the first segment.
So the first dimension was useless. This commit removes this dimension.
3. nrLDPC_coding_segment_encoder: Rename `nrLDPC_prepare_TB_encoding` into `nrLDPC_launch_TB_encoding`
4. nrLDPC_coding_segment_encoder: Remove the useless second rate matching for E2, one rate matching with max(E, E2) does the job.
5. nr_interleaving_ldpc: cleanup
Rewrite code to use different SIMD sizes in a linear fashion.
This means cascading preprocessor directives are used to start from a high SIMD size an decrease it progressively.
6. ldpc_encoder_optim8segmulti: linear usage of SIMD
Use cascading preprocessor directives to include different SIMD sizes and types depending on which are available on the system.
The different loops use a common index that is progressively incremented.
Also add AVX512 version of bits distribution from 8 segments into one byte.

Since this branch aims to bring all the encoded segments packed and contiguous,
it doesn't make anymore sense to have one output array per segment.
Therefore this commit moves the output array to the TB instead of the segment and adapts its size.
TODO: Adapt the size of f where it is relevant.
1. nrLDPC_coding_segment_encoder: pointer not aligned on 64 bits
An undefined behavior was happening because of a shift on a __m64 which
was actually a uint32_t which was not aligned on 64 bits.
This commit suggests a fix by properly loading into a __m64 with _mm_set_pi32
before performing the shift.
2. nr_rate_matching: Filler bits detection
Previously, if the bit selection was reaching Ncb and restarting selection from the beginning of encoded data, the filler bits were detected by testing the bytes again NR_NULL which was equal to 2.
But on this branch the bits of up to 8 segments are stored in one byte while doing rate matching so that one byte could be tested to be a filler while it is not.
So this commit changes the way to test filler bits.
Instead of relying on NR_NULL, bit selection now relies on the offset and size of filler bits.
3. nr_ulsch_coding: missing filling f with zeros
The array `f` of the UE UL HARQ process was not filled with zeros between transmissions.
This is a problem if the encoder does not properly overwrite its output.
In order to avoid such situation, this commit adds a memset to fill `f` with zeros before passing it to the encoder.
4. nrLDPC_coding_segment_encoder: missing init of f to zeros
In the encoder, `f` is not filled with zeros before being used.
`f` is instead somehow filled with arbitrary values.
When writing to `output` by 64 bit vectors, some arbitrary bits may be added after the segment.
Then the arbitrary added ones are not overwritten when writing the next segment because of writing with a logical or.
This commit properly fills `f` and `f2` with zeros.
5. nr_ulschsim & nr_dlschsim: Adapt modulation to new encoder output
The QPSK symbols that are feed to the channel model of nr_dlschsim were determined based on the bytes of the encoder output.
With the new output of the encoder, it had to be reworked to determine the QPSK symbols based on the bits of the encoder output.
1. 3GPP Rate-matching/interleaving on 8-segment blocks, deinterleaving at output of multi-segment processing.
2. Bit-packing done in nrLDPC_coding_segment_encoder.c now instead of nr_scrambling.
Interestingly, it improves performance significantly too.
Tested for AVX512 only for now.
Avoid the use of simde_mm_sign_epi8 which is inefficient on aarch64.
Decoding times are significantly improved on aarch64.

2. --allowerasing downgrades the relevent mesa package(s)

llvm-toolset, but I don't know how to do that.
As per CUS spec, the MTU can be 1500 or 9000 B, where MTU = IQ data format.
Packet length = ethernet header + RTE_PKTMBUF_HEADROOM + MTU
However, xran assumes different definitions of the MTU:
(1) in xran_init_mbuf_pool(): MTU = ethernet header + IQ data format;
(2) in xran_get_num_prb_elm(), xran_init_PrbMap_from_cfg(), xran_init_PrbMap_from_cfg_for_rx(), xran_init_PrbMap_by_symbol_from_cfg(): MTU = complitely wrong (as the IQ data format is not well included).
Additionally, xran assumes that the max MTU 9600 B, instead of 9000 B as per spec.
Nevertheless, I left 9600 B in all config files and docs due to wrong calculation of (2) for the total number of PRBs per fragment.
1. Closes#884 - increase the XRAN_MAX_FRAGMENT from 4 to 6 (sufficient for MTU 1500 with compression 8b)
2. Add new firmware version that supports jumbo frames
3. Update the config file to align with the new Liteon unit in our lab - center frequency, jumbo frames, compression and RU MAC address,
as well as the max DL MIMO layers.

In this MR, we set the packet length to 1428 bytes for UL iperf3 testing using
the -l option to prevent packet fragmentation. Fragmentation is causing packet
drops between the gNB and the UPF, leading to failed UL throughput tests in CI.
Add 5GMM Authentication Failure enc/dec lib and unit test
This MR is introducing the 5GMM Authentication Failure message library as per
8.2.4 of 3GPP TS 24.501. This message is sent from UE to network under certain
conditions. The message is also introduced in stack and is send if the received
ngKSI already in use.
- add new library for 5GMM Authentication Failure enc/dec and unit test
- introduce handler and generate function for NAS Authentication Failure
store ngKSI
- send Authentication Failure if ngKSI is already associated with one of
the 5G security contexts stored in the UE
Closes#852
After capturing the FH packets, we observed that the RU supports the MTU value for jumbo frames.
Therefore, no fragmentation needed on DL.

Fix DMRS for PUCCH format 2

uint32_t *sGold = gold_cache(x2, pucch_pdu->prb_start / 4 + ngroup / 2);
uint8_t *sGold8 = (uint8_t *)(sGold + pucch_pdu->prb_start / 4);
This MR was tested with COTS UE with a bwp_start other than 0, and now PUCCH format 2 is being decoded correctly.
Move this message down, at the end of the function, if no code path
exists under which msg3 allocation might fail despite this log having
been printed.
Assume the minimum grant (min_rb) size to be the bandwidth part size. As
an example: rbStart 0, min_rb=bwpSize=106. This should pass, hence
modify these two conditions.

The functions nr_generate_csi_rs() and nr_ue_generate_csi_rs() are
identical. This commit removes nr_ue_generate_csi_rs() and moves
nr_generate_csi_rs() to nr_phy_common_csirs.c so both gNB and UE can use
the same function.

Signal gNB-DU config update CellStatus from DU to CU
Add the cell status to gNB-DU configuration update message, including
test. Use the gNB-DU configuration update to signal the cell status in
the stack.
This IE was not included in a previous refactoring round, but is at
least necessary to be decoded when interoperating with the OSC O-DU.
Improvements in handling UE context in gNB DU
The goal of this MR is to improve the handling of UE context in gNB DU.
To achieve this goal, the UE structure is created as soon as the gNB
receive a PRACH indication. At that stage the UE is placed in a new
structure containing UEs performing RA, untill RA is complete where it
is moved to the list of connected UEs. To simplify the code and to
improve the handling of initial procedures (see #751), DCI 10 and DCI 00
is used at every stage until the DU receives from CU the indication of
UE RRC reconfiguration being completed.
Remove assert for SRI-PUSCH-PowerControl
SRI-PUSCH-PowerControl is not implemented at this point but its enough
to warn about incorrect power control behavior rather than assert on the
configuration.
Closes#953
This is preparatory work to allow NSA-like modes to be used over F1 in
the future. Notably, it fills the F1 message for UE context setup with
GTP TEID, and fills additional information to "make the F1 encoder
happy" (fill in QFI etc). Also, provide some F1 fixes to make this work.
Remove stale UE connections, if relevant.
sdap_tun_read_thread needs to know if we are gNB/UE. Previously, we
passed this into the thread, but the next commit also needs to for
interface termination, where this info is not available. So, for noS1
mode, pass this in.
Add functionality to trigger the addition of a new RRC UE context (in
the CU) for NSA modes, using F1. This commit makes do-ra and phy-test
modes work. "True" NSA will work in the next commit, which also sends
the X2 addition request answer message.
Use the gNB-DU configuration update to signal the cell status in the
stack. At the DU, modify the code to always send this message --
previously, we only sent this message if a SIB1 update was necessary,
but now it's always, only including SIB1 updates if necessary.
At the CU, as we don't really have a use as of now, print the
information, but don't do anything with it.
Add enc/dec lib for E1 Bearer Context Setup Failure
This MR is adding:
- the enc/dec library
- unit test
- handler and callback in stack
For the E1 Bearer Context Setup Failure.
- rewrite add_UE_to_list() and rewrite remove_UE_from_list() to simplify
list handling
- return pointer from get_new_nr_ue_inst(); it's completely freed by
delete_nr_ue_data()
- have add_new_UE_RA() add UE context to access list; remove with
nr_release_ra_UE()
- have add_connected_nr_ue() only add UE to connected list; to move from
access to connected use transition_ra_connected_nr_ue(); remove with
mac_remove_nr_ue() as previously
- free memory on problems during RA
- add some documentation
- in NSA/HO: check for pre-configured RA process
- there are asserts in all functions to clarify when a UE has RA
In phy-test and do-ra modes, we will trigger a UE context creation after
F1 Setup (because the DU is ready), in a later commit. However, before
this commit, E1 is started after the gnb_app (which triggers F1 Setup).
E1 starts an (integrated) CU-UP; if the E1 Setup arrives after the F1
setup (which creates a UE context), then the E1 setup handler will drop
the newly created RRC context for a do-ra/phy-test mode.
Avoid/minimize this by starting E1 first, so that E1 setup is done
before F1 Setup is completed (this does not make sure the problem does
not happen, but lowers the risk of the above problem).
SRI-PUSCH-PowerControl is not implemented at this point but its enough
to warn about incorrect power control behavior rather than assert on the
configuration.
This commit does not introduce the callback on the CU-UP to trigger
a Bearer Context Setup Failure when the setup of the bearer context was unsuccessful.
This should be handled properly in the stack e.g. in e1_bearer_context_setup (a comment
in the code says "We assume all DRBs to setup have been setup successfully, so we always
send successful outcome in response and no failed DRBs")

Fix for NR UE DLSCH decoding barrier in case of no feedback
In !3291 NTN CI RFsim test fails with the UE being stuck. After some
investigation, this seems to be caused by the scenario where there is no
feedback for DLSCH. In that case there is no need to wait for DLSCH
being completed before generating feedback (there is no feedback).
Fix ASN1 struct double free
When paging, RA and other SI have same PDCCH search space, we should
free the struct once and reset the other pointers to NULL.
Update CN5G images tags to the latest release in all CI pipelines
This MR is updating the tags of the CN5G docker images to the latest
release v2.1.9, for all CI pipelines.
Improve radio for Metanoia RU (and likely others)
We introduced a regression that lowered the achievable DL throughput
with at least the Metanoia RU (i.e., in the configuration and the UE
that we use). git bisect showed up one commit, which does not seem
necessary. We just revert this commit, as it improves the throughput and
does not seem to have a negative impact on performance.
Further, increase RLC buffers a bit. Limit 7.2 pipeline number of layers
to 2.
With PMI reporting working (see HEAD^^), it seems that four layers put
two much processing strain on the machine (cacofonix), which asserts
immediately. In tests, it was found that the same test throughput
(600Mbps) can be achieved with two layers, while not crashing the
machine.
The UE stores PDCCH search spaces from the network in NR_BWP_PDCCH_t
struct within NR_UE_MAC_INST_t. After storing, the pointers otherSI_SS,
ra_SS and paging_SS are updated to point to the stored SS. Multiple
pointers could point to the same stored SS struct depending on
configuration. Then when the UE wants to release the SS, the pointers
are used to free the stored SS using ASN_STRUCT_RESET(). If multiple
pointers point to the same SS, calling ASN_STRUCT_RESET() on all
pointers would lead to double free. So one needs to check for dangling
pointer before freeing.
Instead of using pointers and assigning them during configuration, we
use SS id for otherSI_SS, ra_SS and paging_SS to retrieve the pointers
whenever needed. When the UE wants to release the SS, we make them -1
indicating an invalid SS id.
Add Bearer Context Modification Request/Response enc/dec lib and adopt in stack

Issue 947 and compilation improvements
This MR started with a small commit (03c7f151) to close#947. Little did
I know that I would be taken in a long journey through OAI compilation
hell.
F1AP: Allocate gNB_DU_ID before storing ID
Update the test so it would catch that bug. Check in eq_() that both
gNB_DU_IDs would be present, or not, using xor.
Found while interop testing with OSC DU.
Fix all direct MAC memory leaks
This MR fixes many memory leaks in the MAC that are otherwise shown by
asan if the gNB is started. UEs can be connected and it seems the MAC
does not leak memory. It also fixes a number of memory problems where
e.g., the generation of SIB1 "steals" memory from the
ServingCellConfigCommon. See the commits for more details.
Note that this still leaves behind a lot of memory after calling the new
function mac_top_destroy_gNB(). To see them, add free(mac); in that
function. However, there are no "direct leaks", so it would be feasible
to still clean up (it's just that we don't do it, yet).
I checked. In a "standard" configuration (FR1, 30kHz), the memory leaks
come basically from RRC. Also, the F1 UE context setup message leaks
some memory, which we will handle in the future by adding
encoding/decoding functions that with corresponding utility (free, copy)
functions. On the other hand, the frequent F1 messages (UL/DL RRC
Message Transfer) do not leak memory (they have the utility functions).
A final commit just makes the inability to write nrRRC_stats.log,
nrL1_stats.log, and nrMAC_stats.log, non-fatal to the gNB.
Pass a "type" of RLC operational mode, from which split-type/gNB/UE
decision is derived.

prepare_scd() sets up memory for possible dedicated BWPs to be set up.
If they are not used, they are freed in fix_scd(). [1]
There are two problems:
1. in prepare_scd(), multiple structures are allocated once (for
multiple elements), but inserted once. When trying to free those, the
logic of ASN.1 is to free list elements individually, but then we try
to call free() on each element of the list that has been allocated in
one go. Fix this by doing multiple allocations to be in line with
ASN.1 logic.
2. in fix_scd(), free recursively all data structures, not only the
sequence element itself.
[1] this is horrible. We should only allocate memory if we actually need
it, but let's fix the more urgent problem of memory leaks first. Fixing
the logic problem would be more involved.

O_ACK + O_SR + O_CSI + O_CRC bits in a PUCCH resource provided by

Therefore, the number of PRBs to be used by PUCCH-format2 is M_PUCCH_RB_min,
except if we have zero HARQ-ACK bits, or if we have any HARQ-ACK, is in response
to a PDSCH reception without a corresponding PDCCH. In this case, we must use
the resources indicated in the pucch-CSI-ResourceList and determined as described

In OAI, we have:

Therefore, this MR fixes the prb_size, so that the number of PUCCH-format2 PRBs matches correctly.
Follow up on NAS Registration Accept lib
This MR is a follow up on !2984 (merged).
The goal is to enhance the NAS Registration Accept lib:
- Add regression test for NAS Registration Accept: the goal of this test is to
prevent on the decoding of the NAS Registration Accept sent by the OAI CN5G
- Add equality check and free utility functions to NAS Registration Accept
library
- Free NAS Registration Accept after use: heap memory is allocated for this
message during decoding and shall be free after processing
- Remove harcoded Slice Differentiator (SD) in NAS decode_nssai_ie and update
the processing logic: 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
the presence of the field in the received message and in that scenario, check
the stored value against the one from the UICC. If no SD was received, consider
the UICC SD a valid one.
- Cleanup and other fixes to decode_registration_accept: (1) adopt byte array
(2) move registration result enc/dec to registration accept library (3) check
on buffer lengths (4) add defines whenever necessary (5) simplify the code
Disable the PRACH workaround in NR UE. With the MIB/SIB delay
implemented on the gNB there is no longer a need to delay first
NR UE random access attempt.
This commit introduces a delay mechanism for the first MIB/SIB transmission
in the gNB scheduler to allow PRACH noise estimate to converge stabilize
before first PRACH preamble reception.
Key changes:
- Added the `num_scheduled_prach_rx` variable to gNB_MAC_INST to keep track
of total number scheduled of PRACH receptions. Using uint64_t type to avoid
overflow.
- Updated the `gNB_dlsch_ulsch_scheduler` function to conditionally schedule
MIB/SIB transmissions if `num_scheduled_prach_rx` is at least 100.
The value comes from OAIs implementation of PRACH noise estimate.
fix IP address in 4G UE

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.

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.

in nr_common.c
- NR UE: continuously estimate the frequency offset using PBCH DMRS
- NR UE: add command line parameter --initial-fo to specify known
initial frequency offset
- NR UE: add support for continuous DL frequency offset compensation
--cont-fo-comp
- NR UE: add support for continuous UL frequency offset
pre-compensation. Depending on the main source of frequency offset,
pre-compensate the UL frequency offset (FO) accordingly. Therefore
modify the flag --cont-fo-comp to accept an integer value, where
* 1 specifies, that the main FO contribution comes from the accuracy of the local oscillator (LO)
* 2 specifies, that the main FO contribution comes from Doppler shift
- NR UE: add PI controller to continuous frequency offset compensation
- rfsimulator: enable and correct NTN LEO doppler simulation
- use SIMD to speed up nr_fo_compensation()
- Extend NTN LEO example in RUNMODEM.md to include continuous Doppler
compensation
- NR UE: in nr_adjust_synch_ue() extend the peak search to +/- cyclic
prefix size, esp. for LEO NTN scenarios the timing drifts during
initial sync, which is mostly compensated with
--ntn-initial-time-drift. But there might be a residual time offset,
and by extending the peak search window we make this more tolerant.
- NR UE: remove unused nr_slot_tx_offset, it is unused since commit
f3e60a14
- NR UE: remove now unnecessary local variable
update_ntn_system_information, directly use
UE->ntn_config_message->update instead

Fixes: 30628b820c ("Add encoding/decoding lib for F1AP Setup Response
(Interface Management)")
In various places, e.g., during initialization (before deployment), we
use the name of the CN object, previously including the IP address.
However, the IP might not be available (because the CN is not deployed),
so we would get warnings at this stage. Avoid this by not looking up the
IP.
There is now one place where we have to look up the IP address
separately.
Also, the exception in initialization might be misleading if we used
{self}, because we complain about no node being present, but the {self}
would include a non-existing node name => do not use it.
Add support for 'dl_min_mcs' and 'ul_min_mcs' configuration parameters
Add support for 'dl_min_mcs' and 'ul_min_mcs' configuration parameters,
they will enforce the gNB scheduler to select always a MCS equal or
above its values
In addition to use a min value for MCS, this MR also enables the testing
of a specific MCS value with COTS UE, by setting
xl_min_mcs = xl_max_mcs
example:
dl_min_mcs: 22
dl_max_mcs: 22
ul_min_mcs: 7
ul_max_mcs: 7
In the example above, the scheduler will use always MCS 22 for downlink
and MCS 7 for uplink.
Encapsulate the asn1c call from cmake in a cmake function run_asn1c().

stdout.
Use the new run_asn1c() in all occasions for code generation.
[1] it is quite verbose, with many warnings that we cannot influence nor
suppress, and lists all generated files which is verified by the build
system automatically, anyway.
NR UE: enable concurrent UL slot processing
This commit introduces support for concurrent UL slot processing
Key changes:
- Increased number of UL actors from 1 to 2
- fix several issues related to writing to global variables inside processSlotTX
- Ensure in-order execution of if_module calls by utilizing the preexisting dynamic_barrier structure.
Note: for NTN, concurrent UL slot processing does not work. A flag
`--num-ul-actors X` has been introduced that allows to fix the number of
UL actors to `X` (default is 2).
Add 5GMM Service Reject enc/dec library and unit test
- introduce the library for the NAS Service Reject enc/dec
- add relevant unit test
- add handler
nr_dlsim allocates memory on every SNR iteration without freeing it.
This can lead to memory exhaustion. Fix this by allocating only once
and reuse memory. Also, free it before exit.
NR UE: fix PRACH generation with frequency resource id not 0 when msg1-FDM > 1 in SIB1
When msg1-FDM > 1 (2, 4 or 8) in SIB1, the frequency resource id of
PRACH could be not 0, current PRACH generation only considers frequency
resource id = 0. This MR fixes it, verified with 3rd-party gNB.
Closes#939
RedCap InitialBWP
Prevent RedCap UEs to move to DedicatedBWP
This allows the coexistence of RedCap UEs and non-RedCap UEs in the
same cell by having an InitialBWP with 20MHz and a larger
DedicatedBWP.
Update example RedCap configuration file to have 20 MHz InitialBWP and
40 MHz DedicatedBWP

- This MR keeps a simple ping after the second handover since there are
still issues due to scheduling starting too early, that is as soon as
the UE context is added. This leads to retransmissions that could
eventually lead to a test failure. The issue will be fixed in a future
MR.
add check on connected DU to verify successful handover

the connected DU

Optimization for unused symbols in NR UE

that aren't used, the time domain buffer is memset instead.

feat(oran_fhlib_5g): O-RAN 7.2 FrontHaul Interface on Arm
This MR is enabling the 7.2 FHI on Arm systems.
Even though the performance are yet very bad (UE connection is very
difficult, 100Mbps DL, almost no UL), still I would like to merge this
now since the matter of making the FHI work is rather orthogonal to the
performance issues.
So merging this feature would provide a reliable settlement on top of
which we could then progressively enhance the porting of OAI to Arm.
Especially that would make our work easier by having less features to
rebase regularly on develop.
The main features this MR is made of are:
1. Make the xran patches dual
We provide patches for both E and F releases of xran that handles x86
targets as well as Arm targets. Both patches have been tested on both
types of machines (armix, broadbill). Thanks to @brobert and @changy
for their work on xran.
2. Perform 9-bits BFP compression with ArmRAL
Since the BFP compression implementation provided with xran does rely
heavily on AVX512, we provide an alternative implementation that is
relying on Arm's RAN Acceleration Library (ArmRAL).
As of writing this commit description, only 9-bits compression is
supported. Other IQ width will be added.
This upcoming change does not prevent review to be performed since the
BFP compression functions of ArmRAL are identical except for the IQ
width. Adding further IQ width is therefore very straightforward.
3. Fixes in oran_fhlib_5g to support Arm
The library oran_fhlib_5g needed few changes to successfully compile and
run on Arm systems. Thanks to @brobert for his work on oran_fhlib_5g.
Fix inconsistent maxnoofPDUSessions definitions between NGAP and platform constants
There are 2 different definition of maxnoofPDUSessions (as per 3GPP TS
38.413), one in NGAP lib (set to 16) and one in platform_constants.h
(256 as per specs). The NGAP lib definition is removed in this commit
and replaced by the one compliant with the specs.
This is fixing the warning:

Avoid accessing current_DL_BWP structure when scheduling DCI for other SIBs
Avoid access to mac->current_DL_BWP structure when scheduling DCI for
SIBs other than 1. This is not needed and can cause NULL pointer access
which can happen if the UE has released MAC configuration or has not
started RA yet.
sched_ctrlCommon earlier
This MR configures sched_ctrlCommon earlier, in RCconfig_nr_macrlc().
The objective of this MR is to solve the following Assert in the F1 test:
19897952.126019 [NR_MAC] I Adding new UE context with RNTI 0x3269
/oai-ran/openair2/LAYER2/NR_MAC_gNB/gNB_scheduler_primitives.c:366:15: runtime error: member access within null pointer of type 'struct NR_UE_sched_ctrl_t'
[INFO tini (1)] Spawned child process '/opt/oai-gnb/bin/entrypoint.sh' with pid '7'
[INFO tini (1)] Main child exited normally (with status '1')
Wait before triggering a handover. First, we send it very quickly after
deployment, which can make the DU crash (should be fixed in !3332). Second, a
UE would typically first measure neighbors. While we don't do this with OAI UE,
mimic this somewhat by giving more time.
See also !3332.
* the handover is followed by a sleep and an ping test
This MR keeps a simple ping after the second handover since there are still issues due to scheduling starting too early,
that is as soon as the UE context is added. This leads to retransmissions that could eventually lead to a test failure.
The issue will be fixed in a future MR.
The Bearer Context Modification Request test is adding 1 QoS Flow, therefore the encoding/decoding
is done and this bug does not show. The issue is there when no QoS Flow is mapped in the DRBnGRanModList,
therefore when no memory is allocated for the optional IE, and the member is accessed in the decoding
of the Flow Mapping Information.
As per spec, UE ID shall be reported when the message event configured by
the Event Trigger Style 1 is set to “RRC Setup Complete" message (UE attach), or
“Xn/NG Handover Request” or “F1 UE Context Setup Request” (Intra gNB Handover).
In OAI RAN, Xn/NG Handover is not yet supported, and therefore not added as the trigger event
in this commit.
Additionally, as the Event Trigger Definition Format 1 is common for both "RRC Message" and "UE ID",
E2 node will report the “RRC Setup Complete" message which the xApp will decode and print.

The fronthaul library ships with BFP compression for AVX512 enabled targets.
This commit adds BFP compression for Arm targets by using the ArmRAL library.
Temporarily deactivate DRB integrity protection in SABOX-B200 E1 testcase
to avoid CI failure due to low measured throughput. Our investigation
suggests that the low throughput is likely due to limitation of the UE
(Quectel RM500Q), which appears to restrict the maximum data rate when
integrity protection is enabled. This limitation is not observed with
Quectel RM520N.
- Cleanup and update of "Machines" table:
- remove asterix - not used in CI
- remove nokiabox - not used in CI
- remove orion - not used in CI
- update of "Lockable Resource" for individual machines - synch with
https://jenkins-oai.eurecom.fr/lockable-resources/
- remove column of "IP Address"
- Update information about build pipelines
The healthcheck interval sets when the first health check occurs after the
container starts. Increasing the healthcheck interval helps avoid marking
the container as "healthy" during the initialization phase of PNF. In
particular, USRP initialization of PNF service may take longer, and deployment
failures can occur even after the 10 seconds interval. Extending the healtcheck
interval provides more time for the service before assessing container health.
Remove memset of the UE TX time domain samples array after trx_write in
RU_write()
This memset is unnecessary and can break openair0 libraries. Some
functionalities, e.g. usrp_lib write_thread expect the samples to be
present in the array after trx_write returns.
The array is always set before being sent either in idft or using memset
so there is no risk of sending the same data twice.

Fixes for E1 and PDU session usage
Fix a number of problems in E1 and PDU session handling:
- For multiple PDU session setup reqs, we send a bearer context setup
each time; fix an assert that was triggered on the second bearer
context setup message
- Add a log for E1 bearer context setup, as already done for
modification and release
- If we get a PDU session setup for an existing PDU session, reject it
as required by the spec [actually, it says to reject individual PDU
sessions; keep it simple for now and reject the entire message, which
might not be correct if there is one new PDU session that does not
exist]
- Add a workaround to handle multiple PDU session setup requests that
come in quick succession for different PDU sessions

This means that packets will be sent as soon as possible and no
unnecessary delays are introduced, at the cost of more packets in the

https://www.man7.org/linux/man-pages/man7/sctp.7.html
Refactor core network handling in CI, harmonize code
Prior to change set, there is a highly heterogeneous situation for core
network management in CI code: some log collection is done from groovy
files (when it could be done in python, which is easier for local
development), there are multiple commands to start a CN from XML files,
the code for starting a CN is always different (no one unified way to
start "any" CN), Ping/Iperf require some support in ci_infra.yaml, ...
To help with the above, refactor the handling of core networks in the CI
code as follows:
- define all CNs in ci_infra.yaml (basically how to deploy, undeploy,
collect logs, and on which node)
- make one Python class that reads from ci_infra.yaml and that allows to
start/stop previously defined CNs (and add unit tests...)
- make one XML command for start/stop of CNs, leveraging above class
- leverage the CNs defined in ci_infra.yaml consistently in
Ping()/Iperf()
- delete old code
Furthermore, the following supporting changes/bugfixes are done:
- repair Iperf2_Unidir() and add unit test
- fix a number of invalid escape sequence errors (there are some
remaining, which I will do soon)
- various bug fixes
- remove unused XML steps
Fix: Correctly Read PDU Address IE
The QoS Rules loop correctly moves msg pointer allowing the PDU Address
IE to be read correctly. The PDU Address IE is only processed if it is
provided, otherwise there is a warning.
Closes#931
Add enc/dec lib and unit test for 5GS NAS Service Accept
- add new files for Service Accept fgmm_service_accept.c/.h containing
the enc/dec functions (8.2.17 3GPP TS 24.501)
- enabled compiling
- add unit test
- add handler in stack
This is a hack. With some UEs/CN combinations, PDU session requests
might come in quick succession. Since 38.331 asks us to only have one
reconfiguration at once, we need to delay a second, third, ... PDU
session request until the first has passed, to make one reconfiguration
at a time.
The following cases are covered
- we have a regex whose escape sequences are not to be evaluated in the
string, but given verbatim to the regex engine. Hence, mark them as
raw strings.
- some are parameters for the cmd.run() call, but the parameters are
wrong, so remove that
- there is a `\|` that is also to be passed verbatim

With the server object to be passed into ping test, it's not necessary
to either hardcode an IP address or provide a template. Instead, always
fill the IP address, which simplies the Ping() code.
Verify that we don't have an IP address/hardcoded by throwing an
assertion.
38.413 section 8.2.1.4 says that if PDU session resource setup req
contains an existing PDU session, that one should be reported as failed.
That is rather complicated for us to do; simply reject all PDU sessions
and let the core deal with that.
If two PDU sessions are to be setup, the CU-CP sends two bearer context
setup requests. When running only the CU-UP, we inconditionally tried to
set up the CU-UP UE ID identifiers upon reception of the bearer context
setup request, leading to an assert. Check if the IDs are not already
set up, to avoid assertions in that case.
The REPORT service was hardcoded to only style 4, and therefore not easily extendable.
This commit moves the support for style 4 in a separate function.
Delete duplicated enum structs for RAN Parameter IDs for all the REPORT styles.
They are already defined in "openair2/E2AP/flexric/src/sm/rc_sm/ie/rc_data_ie.h".

Currently we still activated the DL HARQ process for PUCCH transmission,
and only at the time of the scheduled PUCCH transmission, we actually skip sending the ACK.
This is not only unnecessary, it is at least misleading and strange that
DL HARQ processes can be reused in the meantime, even though they are active...
Therefore simply don't activate the DL HARQ process by skipping the call to set_harq_status() if feedback for it is disabled.
This is not really used as of now, because most IPs are hardcoded. See
one of the next commits for the use of this.
To make sure that we have the correct IP, there is some code that
verifies that a hardcoded IP and the CN IP would be the same.
Note: need two separate ci_infra.yaml entries, because
- for FlexRIC, the container name is different (is the tutorial CN)
- for RFsim5G E1, we don't have ext-dn => ping UPF
- call scripts for magma MME-based deployment of OAI 5GC in
ci_infra.yaml
- implement the existing python code through scripts (which does the same)
- save the cql file in the repo, which was previously downloaded every
time
- use for porcepix-cn4g and nano-cn4g (un)deployment, ping, perf, in XML
files
- Use scripts to deploy OpenShift-based 5GC in ci_infra.yaml
- Use for oc-cn5g, oc-cn5g-20897, and oc-cn5g-20897-aerial2
for (un)deployment, ping, iperf in relevant XML files
- Convert hardcoded IP addresses to %cn_ip%
Use the core network class to configure one "end" of these tests. This
will make the tests more generic and predictable, as they are explicitly
configured through two ci_infra.yaml "entities", instead of some
implicit "EPC" IP address given in configuration.
As of this commit, no XML passes this info into the framework, so no XML
step will work. As it is many changes, the following commits will add
the necessary info one by one.
This adds a helper class to manage various core networks in the CI
testing framework. Specifically, it reads from a YAML file information
such as a node, (un-)deployment script (file), log collection
instructions, etc., in order to allow a common interface to be used to
deploy and undeploy various core network implementations.
This commit adds the class (in cls_corenetwork.py) as well as tests for
this class.
These two functions use the EPC class to potentially fill in
EPC/5GC-related information, or start a packet tracer (tshark). The only
pipeline that uses these functions is RAN-gNB-N300-Timing-Phytest-LDPC,
which does not use a core network. This functionality is not used, and
can therefore be removed.
Add a possibility to use an "infrastructure YAML file" to configure both
ends of the iperf2 call through a file.
Fix bugs in Iperf2: at least on my machine, iperf2 start time is logged
at 0.00 not 0.0, so update the regex to match both. Do not overwrite
results if the matched regex (otherwise, the result might be None at the
end) and suppress server output.
Add a unit test to test that this function actually works (on my
machine, with iperf v2.2.1), as well as a unit test for analysis.
The 5GMM library in openair3/NAS/NR_UE/5GS/5GMM/ contains the
all the definitions necessary to do the enc/dec of 5GMM IEs.
5GMM messages can share the same IEs, therefore they can use
common definitions and enc/dec functions.
The goal of this commit is to add common definitions to new shared
5GMM library files. The consumers of fgmm_lib are the functions
defined in the openair3/NAS/NR_UE/5GS/5GMM/ library.
