As per spec, UE ID shall be reported when the message event configured by
the Event Trigger Style 1 is set to “RRC Setup Complete" message (UE attach), or
“Xn/NG Handover Request” or “F1 UE Context Setup Request” (Intra gNB Handover).
In OAI RAN, Xn/NG Handover is not yet supported, and therefore not added as the trigger event
in this commit.
Additionally, as the Event Trigger Definition Format 1 is common for both "RRC Message" and "UE ID",
E2 node will report the “RRC Setup Complete" message which the xApp will decode and print.

The fronthaul library ships with BFP compression for AVX512 enabled targets.
This commit adds BFP compression for Arm targets by using the ArmRAL library.
Temporarily deactivate DRB integrity protection in SABOX-B200 E1 testcase
to avoid CI failure due to low measured throughput. Our investigation
suggests that the low throughput is likely due to limitation of the UE
(Quectel RM500Q), which appears to restrict the maximum data rate when
integrity protection is enabled. This limitation is not observed with
Quectel RM520N.
- Cleanup and update of "Machines" table:
- remove asterix - not used in CI
- remove nokiabox - not used in CI
- remove orion - not used in CI
- update of "Lockable Resource" for individual machines - synch with
https://jenkins-oai.eurecom.fr/lockable-resources/
- remove column of "IP Address"
- Update information about build pipelines
The healthcheck interval sets when the first health check occurs after the
container starts. Increasing the healthcheck interval helps avoid marking
the container as "healthy" during the initialization phase of PNF. In
particular, USRP initialization of PNF service may take longer, and deployment
failures can occur even after the 10 seconds interval. Extending the healtcheck
interval provides more time for the service before assessing container health.
Remove memset of the UE TX time domain samples array after trx_write in
RU_write()
This memset is unnecessary and can break openair0 libraries. Some
functionalities, e.g. usrp_lib write_thread expect the samples to be
present in the array after trx_write returns.
The array is always set before being sent either in idft or using memset
so there is no risk of sending the same data twice.

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

There are 2 different definition of maxnoofPDUSessions (as per 3GPP TS 38.413),
one in NGAP lib (set to 16) and one in platform_constants.h (256 as per specs).
The NGAP lib definition is removed in this commit and replaced by the one
compliant with the specs.
This is fixing the warning:

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.
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.
