Do not assert if the list of phy statistics is full; instead return
NULL.
In most places, this is handled appropriately (we do not store anything
if we can't). In nr_decode_pucch0(), the return value of get_phy_stats()
is used a little bit all over the function, and a constant
if (uci_stats)
uci_stats->variable++;
would look ugly, so make uci_stats point to the stack if we cannot store
in the phy_stats.
the uci_stats variable (pointing to per-UE statistics for UCI) is used
in function nr_decode_pucch0() to store information which is important
beyond statistics, e.g., uci_stats->pucch0_thres as a threshold (which
comes from somewhere else)
This commit refactors to use original or intermediate variables to not
mix uci_stats usage with actual processing.
Also, group uci_stats a bit more.
They use 4G NUMBER_OF_UE_MAX, which is not supposed to be present in 5G.
Further, the mutex and variable are global state; for Paging, we should
use F1.
We can only support up to 30 UEs for SRS. In this commit, we change:
- if the total number of UEs is > 32, throw error during compilation to
raise awareness (32 so that a multiple of two still works, everything
else is confusing, see also next point)
- during runtime, handle gracefully if UID is 30 or 31 to not abort (we
can simply not allocate SRS resources)
Also, refactor config_srs() to always give back new memory; the code is
shorter and clearer. Rename to get_contig_srs() to make it explicit.
- use new ssh class
- do proper logging from multiple services
- use yaml dir
- Use splitlines(), minor modifs of syntax
- check that services are running
- Check all copyin() operations, not only last
- switch to docker compose:
with the use of the new ssh class, we cannot (easily) use the old
docker-compose anymore (which was an alias to docker compose). Switch to
"docker compose".

Set ulimit of core to -1 enable core dumps for file-based core dumping.
Note that it is not necessary for e.g., systemd-coredumpd, but put it
for completeness.
- Return code says if copying succeeded
- Improve handling of the recursive code paths, which copy files or
directories recursively into another directory
- both for RemoteCmd/LocalCmd
Some CI users (OAI developers) expressed that the warning of the `docker
volume prune` before starting RFsim is confusing. To avoid the warning in
the HTML, force the removal; if the volume does not exist, no warning is
emitted.
To still catch possible problems, do not do this in the `terminate.xml`
so we might still see if there are other problems.
The original UL max MCS of 9 was chosen for performance reasons. In the
meantime, machines became faster, and the ULSCH decoding faster. Improve
UL max MCS to be 28 by default to use the complete range of possible
MCS.
Doing only 5 LDPC iterations by default leads to a poor reception
performance, and correspondingly many retransmissions. Increase to 8 as
the new default to improve user experience.
Ensure that the UE has an IP address before continuing the test.
Otherwise, it might happen we ping before the UE is connected.
Do not do this in do-ra and phytest, as they use --noS1, which implies
statically assigned IP address, so IP address check always succeeds(!).
Make RFsim start up faster by starting core and RAN start at the same
time. This speeds up because we do not wait for "healthy" containers
serially, but parallely.
For the RAN, it is safe to start gNB and UE at the same time in SA mode
(as the UE will only attach once the radio, and hence the full gNB, is
ready).
We do not start in parallel in do-ra and phytest, as in these modes the
gNB first has to write a UE-specific configuration file. If we start
both gNB and UE at the same time, the UE might try to read the file
before it is written, leading to a failure.
