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.
These libraries have an (indirect) dependency on T, either by using the
logging module (which in turn depends on T), or through other includes.
The easiest is to depend on the logging module, which will fulfil also
the T dependency.
It would equally be feasible to use the utils target (which in turn
depends on log_headers), but this would necessitate to compile, and does
not seem to be necessary.
This constant seems to be an analogon to NUMBER_OF_UE_MAX; replace with
the latter, as it does the same. (NBIoT does not work, anyway)
Fix dependencies of the NB_IoT target so it compiles.
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
Link E2_AGENT libraries directly into nr-softmodem/lte-softmodem instead
of L2/L2_NR/F1AP. Doing that ensures that simulators, e.g.,
nr_dlsim/nr_ulsim do still compile. It also simplifies the code.
Prior to this, compiling nr_ulsim with E2_AGENT, for instance, resulted
in the following errors, fixed in this commit:
FAILED: nr_ulsim

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
- Limit scope of get_default_rbconfig function: from asn1_msg.c/.h to rrc_gNB_nsa.c where it's used
- Create new rrc_gNB_asn1.c/h files for ASN.1 utility functions: they can be used in other RRC files
- Add nr_rrc_build_pdcp_config_ie function for building PDCP configuration IEs
- Update get_default_rbconfig to use the new PDCP config builder
- Add rrc_gNB_asn1.c to CMakeLists.txt build configuration
The RRC PDU Session struct is converted from a fixed-size array
to a dynamically sized seq_arr. This improves flexibility and
simplifies session management by eliminating arbitrary size limits
and enabling dynamic addition/removal of PDU sessions.
Helper functions and loops have been adapted to use the seq_arr API.
This change is a step toward more robust and maintainable handling
of PDU sessions in the gNB RRC layer.
The "status" state machine remains untouched in this commit and
is refactored in a later commit.
Also:
* add macro to push to seq_arr and return the new element
* move initialization of xid (RRC PDU Session struct) to
find_pduSession (temporary, will be finalized in a later
commit) since with the new seq_arr design the initialization
is no longer possible in the UE context generation (also
does not belong to it, initialize when adding a new PDU Session)
Code cleanup (SRS, config files and more)
- Remove deprecated elements from some configuration files (also closes#997)
- Improve SRS code with a better separation between common code and gNB/UE code
- Other minor compilation improvements
This commit introduces the NG Mobility Management Procedure known as
Handover Preparation. The outbound message is sent by the source NG-RAN
and is known as Handover Required.
* introduce NGAP library for Mobility Management
* introduce NGAP IEs encoder functions for Handover Required and relevant common IEs
* handle RRC trigger in NGAP and Send NGAP Handover Required to the AMF

Align add_boolean_option as per CMake documentation use only ON/OFF for uniformity
The add_boolean_option of CMake is not uniform everywhere. We were using
either True/False or ON/OFF. It is better to be uniform to avoid
confusion.
As an example, see here CMake documentation for an example:
https://cmake.org/cmake/help/latest/module/CMakeDependentOption.html#example-basic-usage
There are also some minor spelling corrections.
some work for better interoperability with srsRAN DU
Just add the minimum to get some user plane traffic going on.
When doing user plane traffic, in the CU logs we have a lot of:
[GTPU] NR-RAN container type: 1 not supported
That will be fixed in another MR, not here.
Add a CU-UP load tester and improve GTP performance
This adds a simple tester program for the CU-UP. It sets up a number of
UEs/bearers in the CU-UP via the E1 interface, then streams data in
downlink/uplink (as seen by the CU-UP). More information is available in
tests/nr-cuup/README.md.
Includes some fixes to properly verify that SCTP is installed, and use
"the right cmake way" to use it in cmake code (see commit for details).
This is a simple CU-UP load tester. It sets up a configurable number of UEs in the
CU-UP, then sends GTP traffic in downlink/uplink in the N3-F1/F1-N3
direction at the CU-UP. It then compares the sent and received data.
Additional parameters, such as amount of traffic, test length, packet
size, and IP addresses/ports are configurable.
To run:
mkdir build && cd build && cmake .. -GNinja && ninja nr-cuup nr-cuup-load-test params_libconfig
./tests/nr-cuup/nr-cuup-load-test
./nr-cuup -O ../tests/nr-cuup/load-test.conf
The tester should be able to detect lost and reordered packets.
Example lost: Receive order 2,3,5,6 (lost packet 4)
=> on packet 2, expected 2, next=expected+1=3
=> on packet 3, expected 3, next=expected+1=4
=> on packet 5, expected 4, diff=5-4=1 (lost 1), next=payload+1=6
=> on packet 6, expected 6
=> 1 lost
Example reordered: Receiver order 2,5,3,6 (lost packet 4)
=> on packet 2, expected 2, next=expected+1=3
=> on packet 5, expected 3, diff=5-3=2 (lost 2), next=payload+1=6
=> on packet 3, expected 6, (reduce lost by 1 to 1), next=expected=6
=> on packet 6, expected 6
=> 1 lost
Example reordered: Receiver order 2,5,3,4,6 (no losses)
remove specific directory for LTE SIM management tools
This is very old code has never been integrated with the "main" OAI
cmake infrastructure and more recent libraries.
This MR integrates the three binaries for LTE virtual sim management in
the regular build process and log system
Remove sctp from all other targets, since we use sctp::sctp on
SCTP_CLIENT (would fail if it does not exist), and SCTP_CLIENT already
fulfils the SCTP dependency.
Move the path to the beginning, so that we can use it early.
Specifically, it was after the SCTP module, and the next commit will use
the Findsctp.cmake module to find SCTP. Use the cmake-proper variable.
Add check to vnf_nr_handle_param_response for when phy_info is not found
The WLS VNF is in charge of Enqueueing the used blocks after usage for transport, this is done by keeping track of all blocks used, and calling WLS_Enqueue for all of them upon receiving a SLOT.indication
The common library exposes functions for the PNF to return the received blocks to the VNF for it to call WLS_Enqueue on them.
This is done in order to ensure the Blocks are returned after processing, also preventing the Dequeueing of blocks that are still being used, i.e. the internal value is not -1
All saved blocks are to be enqueued at the reception of a SLOT.indication by the VNF
Additionally, the definition of NFAPI_MAX_PACKED_MESSAGE_SIZE was moved to nfapi_interface.h and removed from the other headers, this is done to allow to set the maximum message size when using WLS by only changing the value in one place
Fixup fapi_nr_message_header_unpack call in nfapi_hex_parser
[E2 agent] E2AP README update and OAI-FlexRIC CI pipeline improvements
- E2AP README - add OSC nearRT-RIC section; update with proper FlexRIC
links, and explanations on prerequisites, as well as for xApps
- OAI-FlexRIC CI - use separate containers for xApps
- add reference files for CU-UP/CU-CP
- add logging for KPM NSSAI condition
A number of radio-related RRC parameters, e.g., CellGroupConfig,
"originate" at the DU and are sent to the CU for forwarding to the UE
only. Similarly, there are additional parameters, e.g., RLC-BearerConfig
(part of CellGroupConfig), that originate at the DU.
Hence, the DU decides about these parameters, depending on the MAC state
and capabilities. To clarify this, move the existing
openair2/RRC/NR/nr_rrc_config.{c,h} => openair2/LAYER2/NR_MAC_gNB/nr_radio_config.{c,h}
So that developers know that while those are RRC parameters, they
originate at the DU.
In other words, the CU/RRC is not supposed to use any of these functions
in the RRC. Correspondingly, includes of this file have been cleaned up
(and when they are not necessary at the MAC as well).
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-4G: https://jenkins-oai.eurecom.fr/job/RAN-Physim-Cluster-4G/
- RAN-Physim-Cluster-5G: https://jenkins-oai.eurecom.fr/job/RAN-Physim-Cluster-5G/
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
