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
ue txData more contextual, but still global as it is entangled with usrp driver
- txData buffer is global and entangled even in usrp oai driver because of tx
thread feature
- it also makes weird combination with continuous tx usrp bug workaround
- this MR makes most of the calls contextual but keep the globakl txData
- later a MR should remove the global and tackle it with proper context, but we
need to modify gNb, UE, 4G and probably all oai drivers
Fix DMRS for PUCCH format 2
This MR fixes the DMRS for PUCCH format 2.
While at the OAI-UE we have:
uint16_t startingPRB = pucch_pdu->prb_start + pucch_pdu->bwp_start;
uint idxGold = startingPRB >> 2;
uint32_t *seq = gold_cache(temp_x2, idxGold + pucch_pdu->prb_size);
At gNB side, it was missing pucch_pdu->bwp_start, i.e., it was:
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.

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
