At this point we are successfully able to build.
Additionally, we can run the scenario,
however, it does not pass. It seems that the gNB
is not connecting to the proxy correctly. Just
wanted to push the progress so far. FYI, the items
that had to be changed to correct the linking issues
were the following:
- mac_rrc_data_ind_ue vs. nr_mac_rrc_data_ind_ue
- rrc_data_req vs. nr_rrc_data_req
- mac_rrc_data_req_ue vs. nr_mac_rrc_data_req_ue
- rrc_data_req_ue vs. rrc_data_req_nr_ue
- rrc_data_req vs. nr_rrc_data_req
The listed functions should be declard in the LTE/NR
UE directory depending on the functionality. Several
were mixed. i.e.: LTE functions being called in NR UE.
Also, removing siWindowLength, siWindowLength_int,
SIBType, SIBPeriod, and siPeriod_int from the NR UE RRC.
These variable were not used in the NR UE and are defined
for LTE only.
Lastly, in the NR_IF_Module.c of the NR UE, the global
variable def_dci_pdu_rel15 is not accessible. Need to
revisit this. For not it is commented out.
Most notably, nfapi_rx_indication_pdu_t.data type is changed from
`uint8_t*` to `uint8_t[]`. Also, renamed from `data` to
`rx_ind_data` to make it easier to find.
It looks like :
- when running on a Fedora-host
- with generic kernel
- in a container
- even in privileged mode
That is not enough and priority/schedule settings is not allowed.
So at runtime, we check and in case, we don't set up priorities.

This caused the SCTP descriptor to be reset. This
made issues in the X2 interface between gNB and eNB.
Lots of logs added here. Need to fill NR_UE_Capability_Info
properly.
This code allocates memory from the heap:
```
static void *UE_phy_stub_standalone_pnf_task(void *arg)
{
...
UL_INFO->crc_ind.crc_indication_body.crc_pdu_list =
calloc(NB_UE_INST, sizeof(nfapi_crc_indication_pdu_t));
```
I see NB_UE_INST==1.
Then this code:
```
void fill_crc_indication_UE_MAC(int Mod_id,
int frame,
int subframe,
UL_IND_t *UL_INFO,
uint8_t crc_flag,
int index,
uint16_t rnti,
nfapi_ul_config_request_t
*ul_config_req) {
...
nfapi_crc_indication_pdu_t *pdu =
&UL_INFO->crc_ind.crc_indication_body
.crc_pdu_list[UL_INFO->crc_ind.crc_indication_body.number_of_crcs];
```
used .number_of_crcs to index into .crc_pdu_list without first
checking if .number_of_crcs is in range.
When run with multiple UEs, sometimes .number_of_crcs==1 and then
-fsanitize=address complains.
Change is to use NUMBER_OF_UE_MAX instead of NB_UE_INST.
With this change, -fsanitize=address stopping complaining.
Removing references to memcpy_dl_config_req and
memcpy_tx_req because these functions are leaking
memory. For our standalone mode we have created
new/modified memcpy_dl/tx_req functions.
