Avoid accessing current_DL_BWP structure when scheduling DCI for other SIBs
Avoid access to mac->current_DL_BWP structure when scheduling DCI for
SIBs other than 1. This is not needed and can cause NULL pointer access
which can happen if the UE has released MAC configuration or has not
started RA yet.
sched_ctrlCommon earlier
This MR configures sched_ctrlCommon earlier, in RCconfig_nr_macrlc().
The objective of this MR is to solve the following Assert in the F1 test:
19897952.126019 [NR_MAC] I Adding new UE context with RNTI 0x3269
/oai-ran/openair2/LAYER2/NR_MAC_gNB/gNB_scheduler_primitives.c:366:15: runtime error: member access within null pointer of type 'struct NR_UE_sched_ctrl_t'
[INFO tini (1)] Spawned child process '/opt/oai-gnb/bin/entrypoint.sh' with pid '7'
[INFO tini (1)] Main child exited normally (with status '1')
Fixes for E1 and PDU session usage
Fix a number of problems in E1 and PDU session handling:
- For multiple PDU session setup reqs, we send a bearer context setup
each time; fix an assert that was triggered on the second bearer
context setup message
- Add a log for E1 bearer context setup, as already done for
modification and release
- If we get a PDU session setup for an existing PDU session, reject it
as required by the spec [actually, it says to reject individual PDU
sessions; keep it simple for now and reject the entire message, which
might not be correct if there is one new PDU session that does not
exist]
- Add a workaround to handle multiple PDU session setup requests that
come in quick succession for different PDU sessions

Turn off any Nagle-like algorithm for SCTP
This means that packets will be sent as soon as possible and no
unnecessary delays are introduced, at the cost of more packets in the
network.

Refactor core network handling in CI, harmonize code
Prior to change set, there is a highly heterogeneous situation for core
network management in CI code: some log collection is done from groovy
files (when it could be done in python, which is easier for local
development), there are multiple commands to start a CN from XML files,
the code for starting a CN is always different (no one unified way to
start "any" CN), Ping/Iperf require some support in ci_infra.yaml, ...
To help with the above, refactor the handling of core networks in the CI
code as follows:
- define all CNs in ci_infra.yaml (basically how to deploy, undeploy,
collect logs, and on which node)
- make one Python class that reads from ci_infra.yaml and that allows to
start/stop previously defined CNs (and add unit tests...)
- make one XML command for start/stop of CNs, leveraging above class
- leverage the CNs defined in ci_infra.yaml consistently in
Ping()/Iperf()
- delete old code
Furthermore, the following supporting changes/bugfixes are done:
- repair Iperf2_Unidir() and add unit test
- fix a number of invalid escape sequence errors (there are some
remaining, which I will do soon)
- various bug fixes
- remove unused XML steps
Fix: Correctly Read PDU Address IE
The QoS Rules loop correctly moves msg pointer allowing the PDU Address
IE to be read correctly. The PDU Address IE is only processed if it is
provided, otherwise there is a warning.
Closes#931
Add enc/dec lib and unit test for 5GS NAS Service Accept
- add new files for Service Accept fgmm_service_accept.c/.h containing
the enc/dec functions (8.2.17 3GPP TS 24.501)
- enabled compiling
- add unit test
- add handler in stack
This is a hack. With some UEs/CN combinations, PDU session requests
might come in quick succession. Since 38.331 asks us to only have one
reconfiguration at once, we need to delay a second, third, ... PDU
session request until the first has passed, to make one reconfiguration
at a time.
The following cases are covered
- we have a regex whose escape sequences are not to be evaluated in the
string, but given verbatim to the regex engine. Hence, mark them as
raw strings.
- some are parameters for the cmd.run() call, but the parameters are
wrong, so remove that
- there is a `\|` that is also to be passed verbatim

As parent. The second change has no escape sequence, but since it's also
a regex, mark it as raw for uniformity (it doesn't hurt either).

With the server object to be passed into ping test, it's not necessary
to either hardcode an IP address or provide a template. Instead, always
fill the IP address, which simplies the Ping() code.
Verify that we don't have an IP address/hardcoded by throwing an
assertion.
38.413 section 8.2.1.4 says that if PDU session resource setup req
contains an existing PDU session, that one should be reported as failed.
That is rather complicated for us to do; simply reject all PDU sessions
and let the core deal with that.
If two PDU sessions are to be setup, the CU-CP sends two bearer context
setup requests. When running only the CU-UP, we inconditionally tried to
set up the CU-UP UE ID identifiers upon reception of the bearer context
setup request, leading to an assert. Check if the IDs are not already
set up, to avoid assertions in that case.
Currently we still activated the DL HARQ process for PUCCH transmission,
and only at the time of the scheduled PUCCH transmission, we actually skip sending the ACK.
This is not only unnecessary, it is at least misleading and strange that
DL HARQ processes can be reused in the meantime, even though they are active...
Therefore simply don't activate the DL HARQ process by skipping the call to set_harq_status() if feedback for it is disabled.

Fix SRS report TLV unpack
Changes the SRS unpacking to not expect padding to be present in the buffer when
working with Aerial, with which the report TLVs are not padded to the nearest
32-bit boundary. This issue was found when using a UE with 1 SRS port, which
causes the TLV to not have a length divisible by 4. Also adds a function to pull
X amount of bytes into a uint32_t, which is used to process the last 4 byte
block of the TLV, only pulling the bytes which are not padding. Completed the
SRS.indication dumping procedure to print out the report TLV. Changed the
SRS.indication unitary test to fill the last 4 byte block of the report TLV
appropriately according to the length ( which ensures the padding bytes are set
to 0 )
This is not really used as of now, because most IPs are hardcoded. See
one of the next commits for the use of this.
To make sure that we have the correct IP, there is some code that
verifies that a hardcoded IP and the CN IP would be the same.
Note: need two separate ci_infra.yaml entries, because
- for FlexRIC, the container name is different (is the tutorial CN)
- for RFsim5G E1, we don't have ext-dn => ping UPF
- call scripts for magma MME-based deployment of OAI 5GC in
ci_infra.yaml
- implement the existing python code through scripts (which does the same)
- save the cql file in the repo, which was previously downloaded every
time
- use for porcepix-cn4g and nano-cn4g (un)deployment, ping, perf, in XML
files
- Use scripts to deploy OpenShift-based 5GC in ci_infra.yaml
- Use for oc-cn5g, oc-cn5g-20897, and oc-cn5g-20897-aerial2
for (un)deployment, ping, iperf in relevant XML files
- Convert hardcoded IP addresses to %cn_ip%
Use the core network class to configure one "end" of these tests. This
will make the tests more generic and predictable, as they are explicitly
configured through two ci_infra.yaml "entities", instead of some
implicit "EPC" IP address given in configuration.
As of this commit, no XML passes this info into the framework, so no XML
step will work. As it is many changes, the following commits will add
the necessary info one by one.
This adds a helper class to manage various core networks in the CI
testing framework. Specifically, it reads from a YAML file information
such as a node, (un-)deployment script (file), log collection
instructions, etc., in order to allow a common interface to be used to
deploy and undeploy various core network implementations.
This commit adds the class (in cls_corenetwork.py) as well as tests for
this class.
FHI72: Management plane support
At the moment, tested with Benetel 550 and 650 RUs FW v1.2.2
- support for multiple RUs
- RPCs implemented: <connect>, <subscribe>, <get>, <supervision-watchdog-reset>,
<edit-config>, <validate>, <commit>, <disconnect>
- read PTP sync status from operational datastore xml
- get vendor name, and for xran store RU MAC, MTU and IQ bitwidth and PRACH
offset, and transfer this info
- store interface name, low-level-tx/rx-endpoint names, tx/rx-carrier names,...,
from operational datastore xml
- add reference gNB/DU config files with M-plane support
- update FHI readme
