Pass UE context, without protocol_ctxt_t, for cleanup. Remove the return
from within the switch, as this would lead to memory leaks; nothing is
executed after the switch statement (except for freeing memory).
The existing check for the initialization of GTP is wrong; GTP returns
-1 if it could not initialize. Correct this, such that the DU will stop
if GTP cannot be initialize.
If we continue, the DU is requested to set up a GTP tunnel; because GTP
is not initialized, it assumes it is in monolithic/no F1, and does not
set up a tunnel. The F1 UE Context setup response encoder then fails
with this assertion:
Assertion (tnl->teid > 0) failed!

Prior to this commit, if we receive an Initial Context Setup Request for
a UE that has AS security set up, the gNB asserts with
Assertion (!ue_p->as_security_active) failed!

However, TS 38.413 says:
> The AMF may initiate the Initial Context Setup procedure if a
> UE-associated logical NG-connection exists for the UE
(I interpret this as "it might happen anytime")
> store the received Security Key in the UE context and, if the NG-RAN

(I interpret this as "do not set up AS security again")
In this commit, handle if we receive an Initial Context Setup Request
for an existing UE context. As said in the spec, we store the keys. If
security is not active, we trigger RRC Security Mode Command. If it is
active, we skip Security, and directly set up a PDU session. If there is
also no PDU session, we simply forward the NAS message, and acknowledge.
If there was no AS security, after security, the gNB would trigger the
setup of PDU sessions (if any), and then forward any NAS PDUs, which is
stated in the if block if AS security is already active.
This changes the way T_IDs are defined. The T_ID macro was using a integer to pointer cast in
order to provide type safety. This trick disables some compiler optimizations, as explained
here: https://clang.llvm.org/extra/clang-tidy/checks/performance/no-int-to-ptr.html.
Removing the type cast reenables the compiler optimizations.
Prior to this commit, the include path for some libraries found through
pkg-config when cross compiling is not correct:
$ grep include CMakeCache.txt
blas_INCLUDEDIR:INTERNAL=/usr/include/x86_64-linux-gnu
...
This is because we did not tell pkg-config to search in the right path.
Since for cross-compilation, we install packages in parallel in the
system, override the primary directory where the .pc files located, in
the cross-compilation toolchain file for cmake.
Closes: #746
Since long long is the bigger type ( 8 bytes ) of the two used ( long long and uint32_t ),
and long long is also available on ARM, change this parameter to always have this type.
This allows to always use format specifier '%lld' in the logs that use TICK_TO_US, which would otherwise return long long or uint32_t depending on architecture.
Set a maximum SNR value using the "-S" option to ensure that nr_dlsim
or nr_ulsim is executed only for a given SNR. This approach allows us
to verify the success of the encoding/decoding process at the specified
SNR. Check if the test succeeds is not yet implemented (currently we
only retrieve an information about encoding/decoding processing time).
To be implemented in the separate MR.
Always execute all the nr_dlsim/nr_ulsim tests even if one of them
fails. Each test takes around 5s, so we can execute them all to get
results for all the test scenarios.
which will drop PUCCH 2 indications that are detected as DTX. For the
moment this uses the same pucch0_dtx_threshold value indicated in L1
section of the configuration file.
rrc_gNB_process_security() does not only set (process) the security
algorithms, but also checks for those. However, we don't use the check.
Simplify the function, to reintroduce the check later. Rename to
set_UE_security_algos() to better reflect what the functions do.
- remove Sphex UE - not used anymore
- remove RAN-L2-Sim-Test-5G from a list of pipelines - currently disabled
- 4G RFSim was moved to cacofonix
- minor cleanup

3GPP 38.331: If absent, the UE applies the SCS as derived from the prach-ConfigurationIndex in RACH-ConfigGeneric (see tables Table 6.3.3.1-1, Table 6.3.3.1-2, Table 6.3.3.2-2 and Table 6.3.3.2-3, TS 38.211 [16]).
This procedure for msg1_SubcarrierSpacing NULL is not implemented, so we aplly the same value of UL SCS.
Introduce CMakePresests.json which is a simple way to perform incremental build using cmake
New configure resets were added:
- default: Configure compilation with default options
- tests: Same as above but ENABLE_TESTS and SANITIZE_ADDRESS is ON
New build presets were added:
- 5gdefault: Build the software for NR rfsimulator test
- default: same as 5gdefault
- 4gdefault: Build the software for LTE rfsimulator test
- tests: build all unit tests
To configure using configuration preset:
`cmake --preset <preset_name>`
To build using a build preset:
`cmake --build --preset <preset_name>`
