Update instructions and CI for cross-compilation on Ubuntu 22.
Note that for the dockerfile, we use egrep -L which has changed and does
not exit with code 0 on no match. Instead, use -vqz to invert return
code (0 if nothing found, otherwise 1).
This updates all images in the CI to Ubuntu 22. It also updates
corresponding documentation. Remove python(2) from the image, as it is
not needed. Update documentation.
It seems that the gcc coming in Ubuntu 22 does not like
stack-protector-strong, so remove it as well.
Since we compile Flexric, which does not support Ubuntu 22's default
gcc-11 (it hits a compile bug), switch to gcc-12 manually.
Since we update the compiler, we also need to be careful to use the right
address sanitizer version (which is bundled with the compiler version).
To avoid a reinstallation of the wrong asan version in target images, we
modify Ubuntu 22 targets to copy libasan from the base image. This is necessary
since we use update-alternative in the base image, but we don't want to
install compilers in the target images to use update-alternatives to
install the right asan version... This should be undone when switching
to Ubuntu 24 in the future, as it will have a newer default gcc version,
such that we don't need to update the compile in the first place.
Upgrade libpython in lteUE for U22 upgrade to make it compatible with
UHD.

In some testcases, especially when iperf test duration is short (10s),
client does not report on time and report collection is interrupted.
This commit increase timeout for iperf/iperf3 commands.
- neighbour_config.conf file includes neighbour and measurement related parameters
Neighbour List:
- nr_cellid: the identity of existing cell who has neighbour
- neighbour_cell_configuration(list): includes the identity parameters
of the neighbour cell such:
- gNBID (incase of N2 Handover / to be identified from AMF)
- nr_cell_id (target gNB needs to consider)
- physical_cellId (needed for measurement reporting)
- absoluteFrequencySSB (needed for measurement reporting)
- subcarrierSpacing (needed for measurement reporting)
- plmn / tracking area code (incase of N2 Handover / needed for AMF
to identify / allow HO)
NR Measurement Configuration
- Periodical
- enable (default is 0, 1 enables the reporting)
- includeBeamMeasurements, maxNrOfRS_IndexesToReport (configurable
reporting parameters)
- A2
- enable (default is 0, 1 enables the reporting)
- threshold , timeToTrigger (configurable reporting parameters)
- A3
- cell_id (the nr_cellid of neighbour cell. So this A3 parameters
will be used for the neighbour
- [-1] means default. so it can be applied to any neighbour if
there is no specific config
- Neighbour specific A3 Threshold can be used or default can be
selected depending to the neighbour planning
- The neighbour-config.conf specifies, apply default A3 for
neighbours 3 and 4 | apply specific one for neighbour 2
- offset, hysteresis, timeToTrigger (configurable reporting parameters)
the neighbour_config.conf can be included in the gNB.conf file. Example
is given: gnb.sa.band78.106prb.rfsim.neighbour.conf
A sequence array container is used for neighbour cell configuration. RRC
structure has this container. A Measurement configuration structure is
defined. This structure has Periodical / A2 Event structures and also a
sequence container for A3 Event List.
These structures are filled during the initialization. While F1 Setup
Response is coming from DU to CU, the intra frequency / inter frequency
neighbour decision is given for the existing cell. Also new neighbours
could be added here if needed.
With the capabilities now given as part of this MR, it happens that when
checking the "docker compose config", the container_name might not be
close to the service name. Something like
service:
cap_drop:
...
cap_add:
...
container_name:
This is inconvenient, as the previous grep for the service name + 3
lines might not cover the service name. To circumvent this, give the
service name directly in "docker compose config". (no clue why it has
not been done like this from the start)
- sa_b200_gnb
- sa_aw2s_gnb
- sa_e1_b200
- sa_f1_b200
- sa_sc_b200_gnb
- nsa_b200_gnb
By default, the container has no access to /dev. Mount all USB devices
into the container to ease usability: by default, USB devices are
mounted under /dev/bus/usb using the bus ID, which is different on every
system and might change on reboots or with (un-)plugging USB devices.
Hence, mount all USB; the process has not many capabilities anyway, and
thus might not do much harm.
A proper solution would be to write a udev rule to mount a device using
its vendor and product ID, and only mount the corresponding device into
the container.
- SA 2x2 tests on 60 and 100 MHz
- N310-based OAI gNB + UE
Give SYS_NICE and IPC_LOCK for performance. On the UE side, give
NET_ADMIN (for interface bringup) and NET_RAW (for ping an TUN).
Use correct baseTag for Unit Tests build in execution:
- if build_helper or othe files changed, which would trigger rebuild of
ran-base, use the corresponding ci-temp tag
- use that tag consistently afterwards
In some pipelines, it happens that iperf3 is hanging on 100% CPU load.
In these cases, a simple TERM signal does not seem to be enough to kill
it; KILL is necessary.
While e.g., RemoteCmd's driver paramiko has a timeout command, the
documentation [1] is not really clear how it is trying to stop commands.
Since it effectively does not stop, we have to assume it is only sending
TERM.
To remedy this, use the timeout command to start iperf3. We use option
-v for diagnose timeouts on stderr, and send KILL after an additional 3
seconds (-k3) if TERM does not succeed. The timeout is sent to the same
duration as the overall iperf timeout.

make sure the SSB is offset by 4 PRBs from the BW start.
Therefore, the ARFCN for the SSB center must be offset by 14 PRB from the ARFCN for the BW start.
This reverts commit eaf28414ca.
This assertion was introduced as we (wrongfully) thought we needed to
calculate the SSB ARFCN at the CU. Since PBCH might carry one bit, which
is not available at the CU, only certain SSB ARFCNs would have been
possible.
With the availability of the SSB ARFCN through the
MeasurementTimingConfiguration, this is not necessary anymore.
These functions enables (un)deployment of the OAI CN v2.0.1, increase
reliability and speedup overall CN (un)deployment compared to current
implementation.
Use "--wait" helm option to wait for deployment/undeployment of the CN.
Wait for pods to be in a ready state before marking the release as
successful. If not deployed/undeployed before timeout, marked as
unsuccessful.
Hardcode path for OC CN5G deployment/undeployment
- Remove unused AmariUE config file, replace by new one - for PLMN 00102
- Change frequency of AW2S pipeline - Move center frequency by 40 MHz to avoid interferency with other setups
in the lab. Set center frequency to ~ 3450 MHz.
After the recent update of matix, collected logs contain color codes
and we did not find the way to switch them completely off.
Replacement of "docker compose logs" by "docker logs" resolves this
issue. This commit includes changes related to "docker logs" usage.
Unlike the previous commit, in noS1, we cannot use Attach(), as noS1
automatically brings up an interface, no matter whether the connection
succeeded or not. Therefore, consistently wait a bit longer to increase
the chance that the radio is really up.
For various reasons, the UE might take longer to connect to the eNB. A
simple sleep might not be enough; instead, use Attach() to actively wait
that the UE gets an IP address. The added bonus of this function is that
it will also stop&restart a UE if it did not attach, i.e., it will try
multiple times to attach the UE.
