some work for better interoperability with srsRAN DU
Just add the minimum to get some user plane traffic going on.
When doing user plane traffic, in the CU logs we have a lot of:
[GTPU] NR-RAN container type: 1 not supported
That will be fixed in another MR, not here.
Interoperability testing with srsRAN DU shows than when receiving
RRCReconfigurationCompleteIndicator in a UEContextModificationRequest
the DU replies in the UEContextModificationResponse with an empty
CellGroupConfig.
This CellGroupConfig is encoded as 2 zero bytes. Let's ignore this
message when we receive it, don't forward it to the UE in a
RRC Reconfiguration, as it should per standard (38.473 8.3.4.2):
If the CellGroupConfig IE is included in the DU to CU RRC Information
IE contained in the UE CONTEXT MODIFICATION RESPONSE message, the
gNB-CU shall perform RRC Reconfiguration as described in TS 38.331 [8].
The CellGroupConfig IE shall transparently be signaled to the UE as
specified in TS 38.331 [8].
To be removed/reworked in the future if the interoperability
situation improves.
This is in 3GPP TS 38.425.
Because it was not done, there was a problem of interoperability
between openair CU and srsran DU. No DL traffic was reaching the UE.
A new GTPU API function is introduced: gtpv1uSendDirectWithNRUSeqNum().
It is only used in the gNB CU, in PDCP. So it was decided to not add a
new parameter to gtpv1uSendDirect() but instead add a new API function.
separate computation of size and value for DCI precoding information
This removes stuff that is only relevant for the gNB from the common
functions and moves it to the gNB scheduler functions (related to UL
precoding). In principle no functional change.
2 functions with same name as static to make it clearer they are separate.
remove unused copy of log_level global var.
remove threequarter sampling variable from the radio board general
configuration. The decision of sampling rate is made above. A better
behavior can be done later, like ask to the radio board what sampling
rate it can do,then use it to decide the appropiate sampling rate from
the gNB configuration. In UE case, it is another issue, as the sampling
rate would change after we decode SIB1, but also it is not developped
yet.

Improve MAC docs for MCS and docker for BuildKit usage
See commits for details. The first one is for fixing an omission in
!3281, the second to clarify docker build usage.
Closes: #973
CI: speed up and simplify build, remove unnecessary Python code, remove --eNB* parameter list
This cleans up the CI framework for running end-to-end tests, and
improves the integration with OAI code. Specifically
- cleanup build_oai and helpers to output all text, which is captured
better by the CI
- build some images in the Cluster-Build in parallel to increase speed
- remove all --eNB{,1,2}{IPAddress,UserName,Password} variables. Those
were indexed through "instance" and "server ID" and are replaced with
the actual node name. I consider further cleanup to introduce a
"global" XML file node name so we don't need this in each step and
instead define this once.
- individual cleanup
A previous commit changed to use archiveArtifact() to recover CI logs,
and then attempted to "guess" the L1/MAC stats file name through a
regex. However, the format "enb-[0-9]+" is not correct, as
archiveArtifact() puts the task ID ("[0-9]+") BEFORE the file name
(here, "enb"). So, make it more generic and match the final "-enb.log"
("$" means "end of string").
Fixes: 244ea8fc22 ("Use archiveArtifact() for TerminateeNB()")
Many of these tests exit with an exit code != 0. Thus, the CI
automatically logs the result. Rather, write everything including stderr
to the file for analysis.
Also, rewrite the file with ">" instead of appending through ">>". While
appending works because the CI removes files after archiving, it seems
"cleaner" to remove files.
It is superseded by the CreateWorkspace() function and task step (which
removes and recreates a workspace), and this option was not actually
used in any function except for the build of unit tests, but no XML
step actually specified this option.
After having transitioned to direct node names in the XML, these
parameters are not relevant anymore.
The best way to view this patch is with
git show <SHA> --ignore-all-space
Remove this class. It is not safe to use (no return codes, can get out
of sync), hardcodes the use of passwords, and it's API is cumbersone.
More explanations can also be found in !1867. It is superseded by
cls_cmd.py
Since 28ce0dc444 ("Main: pass in ctx"), the CI always collects logs
into cmake_targets/log/. Hence, LogCollecteNB() is never called. We can
remove it.
Further, change the cmake_targets/log/ to ci-log/, which is shorter, and
append a / on the zip path to make sure that only contents is zipped.
Reimplement these functions by
- using cls_cmd
- retain only the necessary steps from the timing-phytest function
- pass in ctx and node information, instead of server ID
- remove all superfluous variables that don't seem to be used
- make some lists (corresponding indices are "server ID") into normal
variables.
Pass node directly from XML to these functions
- BuildClusterImage()
- BuildImage()
- BuildProxy()
- BuildRunTests()
instead of reading the "server ID" and looking up from
eNB_IPAddress/eNB1_IPAddress/eNB2_IPAddress.
Improve the proxy build unit test by properly passing ctx information.
