In case of noS1-mode, we initialize the 'logicalChannelBearer_exist' array element for the pre-configured DRB0 in function 'nr_l2_init_ue()'.
That array is indexed with the LCID.
For DRB0, the LCID is 4.
Unfortunately, the code incorrectly used the array at index 0.
Therefore, the UE sent neither scheduling requests nor buffer status reports, what resulted in extremely poor UL throughput.
nr_mac_prepare_ra_ue() is called with the scheduler being locked via
NR_SCHED_ENSURE_LOCKED(), but if there is no free RA process, it
unlocks the scheduler via NR_SCHED_UNLOCK(). This is commit fixes this.
In short, when calling nr_mac_prepare_ra_ue(), the scheduler is locked,
and should always return with the scheduler being locked.
* New folder named XNAP created inside openair2
* Added ASN File(38423.asn) for XNAP and .cmake(38423.cmake) for the same inside XNAP.
* CMakeLists.txt files changed to support .C and .H file generation for XNAP
- move following radios: AW2S, BladeRF, IRIS, LMSSDR, RFsimulator, USRP
- move following transports: Ethernet, benetel4g, benetel5g
- for each: create independent cmake variable to switch compilation
on/off, in order: OAI_AW2S, OAI_BLADERF, OAI_IRIS, OAI_LMSSDR,
OAI_SIMU, OAI_USRP, OAI_ETHERNET, OAI_BENETEL4G, OAI_BENETEL5G
- Remove RF_BOARD variable, allows to compile multiple boards at once
- where applicable: remove USERSPACE/LIB in path, i.e., move files up to
directories, as all are userspace libraries
Note that with the above, it is now mandatory to enable a radio
implementation before compiling it, e.g., for USRP:
./build_oai -w USRP
cmake .. -DOAI_USRP=ON && ninja oai_usrpdevif
First, we do not include openssl globally using `include_directories()`,
as most modules don't need it. Further, it is linked into SECURITY, and
removed from all other targets (they don't need it, only SECURITY).
Finally, remove a header include in NR PDCP that is not needed
ENB_MODE is a cmake option to swap the order of include directories.
This has historical reasons; before OAI used cmake, it was very
sensitive to the order of includes. Nowadays, the order does not matter.
Remove this option, and fix the compilation issues that arise while
doing so.
