it safes typing and allows longer scenario configs without exceeding
filename limit.

this patch adds the ability to configure NR cells with
Amarisoft eNB. It adds the new DRB-NR template and updates
the normal enb.cfg template to allow using it as LTE only
or with NR cells (5G NSA).

this patch adds generic support for custom frequency bands to the ms class.
it then extends the config template for AmariUE to use them.
we set the default values for EARFCNs for DL/UL to the old values.

this config option overwrites the EARFCN config that is typically
used to tell the UE the bands to scan for cells. When custom
frequencies are used, this option allows to set them explicitly.

the UEs count param, if specified, is mapped into the config
values of the EPC so it can be used for template rendering.
Since we only have one count parameter, its added to the first
subscriber. 1 is the default value and its used when no count
param is specified.
this allows to run the Amarisoft UE simulator with the Amarisoft EPC
without having to create subscriber entries for each simulated UE.

Despite open5gs allowing to change the GTP ports in the config file, in
reality changing those values to something else than the standard prot
will fail. Hence, we must use the standard port. As a result, we must
use different IP addresses in each process to avoid ip+port collisions.
Let's use some loopback addresses which shouldn't require extra
configuration on the host, and still only requiring 1 run_node as per
existing EPCs, with the limitation that only 1 open5gs EPC instance can
be run at one in a given run_node.

we previously mixed component specific and component agnostic APIs
(stdout vs. log file for example) for setting and retrieving KPI.
This patch propose to use a single abstract get_kpis() method for
all components that can be enriched with component-specific
stuff as desired.
In the case of srsLTE blocks, the main implementation will
remain in srslte_common() and is shared among srsENB/srsUE/srsEPC.
The KPI analyzer in srslte_common() extract and also manages
all three KPI sources (log, csv and stdout) independently.
In addition to the get_kpis() method that always returns a flat
dictionary, it also exposes get_kpi_tree() that return
a dict of KPI dicts that will be used for the Junit.xml generation.

osmo-bts.git ae09c8acb4aa93284cdb44f8bbdc14533dc4fa52 modified code to
avoid calling pcu_tx_info_ind() if pcu socket was not connected. Since
osmo-gsm-tester relied on log message sent from within that funtion to
find out whether BTS was able to handle PCUIF connections, that log line
is not printed anymore and hence the function ready_for_pcu() fails to
ever return true.
As a result, gprs tests for sysmo and oc2g bts types always fail with a
timeout.
Other BTS types are not affected (such as osmo-bts-trx) because in there
we simply check whether the osmo-bts process is running.

This patch enables setting cipher and integrity algorithms
in Amarisoft eNB and srsENB via scenario files. If no
settings are defined following defaults are applied:
- Cipher algorithm: EEA0, EEA2, EEA1
- Integrity algorithm: EIA2, EIA1, EIA0
Example of setting cipher algorithms:
- 4g:srsue-rftype@uhd+srsenb-rftype@uhd+mod-enb-cipher@eea1+mod-enb-cipher@eea0+mod-enb-nprb@6

this patch adds the stdout counter to count events happening
on the stdout (known from the UE already) to the common
process class so they can also be used from the eNB (and other objects)
In addition, we add a PRACH counter to be used for tests.

To expand the test capacities we would like to introduce
Android UEs as new modems. Currently the following tests
are supported:
- Ping
- iPerf3 DL/UL
- RRC Mobile MT Ping
In the following is a small description.
Prerequisites:
- Android UE
- Rooted (Ping, iPerf, RRC Idle MT Ping)
- Qualcomm baseband with working diag_mdlog (RRC Idle MT Ping)
- iPerf3
- Dropbear
- OGT Slave Unit
- Android SDK Platform-Tools
(https://developer.android.com/studio/releases/platform-tools#downloads)
- Pycrate (https://github.com/P1sec/pycrate)
- SCAT
clone https://github.com/bedrankara/scat/ & install dependencies
checkout branch ogt
symlink scat (ln -s ~/scat/scat.py /usr/local/bin/scat)
Infrastructure explaination:
The Android UEs are connected to the OGT Units via USB. We
activate tethering and set up a SSH server (with Dropbear).
We chose tethering over WiFi to have a more stable route
for the ssh connection. We forward incoming connections to
the OGT unit hosting the Android UE(s) on specific ports
to the UEs via iptables. This enables OGT to issue commands
directly to the UEs. In case of local execution we use ADB
to issue commands to the AndroidUE. The set up was tested
with 5 Android UEs connected in parallel but it should be
scalable to the number of available IPs in the respective
subnet. Furthermore, we need to cross compile Dropbear
and iPerf3 to use them on the UEs. These tools have to be
added to the $PATH variable of the UEs.
Examplary set up:
In this example we have two separate OGT units (master
and slave) and two Android UEs that are connected to the
slave unit. An illustration may be found here: https://ibb.co/6BXSP2C
On UE 1:
ip address add 192.168.42.130/24 dev rndis0
ip route add 192.168.42.0/24 dev rndis0 table local_network
dropbearmulti dropbear -F -E -p 130 -R -T /data/local/tmp/authorized_keys -U 0 -G 0 -N root -A
On UE 2:
ip address add 192.168.42.131/24 dev rndis0
ip route add 192.168.42.0/24 dev rndis0 table local_network
dropbearmulti dropbear -F -E -p 131 -R -T /data/local/tmp/authorized_keys -U 0 -G 0 -N root -A
On OGT slave unit:
sudo ip link add name ogt type bridge
sudo ip l set eth0 master ogt
sudo ip l set enp0s20f0u1 master ogt
sudo ip l set enp0s20f0u2 master ogt
sudo ip a a 192.168.42.1/24 dev ogt
sudo ip link set ogt up
Now we have to manually connect to every UE from OGT Master
to set up SSH keys and verify that the setup works.
Therefore, use:
ssh -p [UE-PORT] root@[OGT SLAVE UNIT's IP]
Finally, to finish the setup procedure create the
remote_run_dir for Android UEs on the slave unit like
following:
mkdir /osmo-gsm-tester-androidue
chown jenkins /osmo-gsm-tester-androidue
Example for modem in resource.conf:
- label: mi5g

it turned out that we have to reduce the MCS when using QAM256,
especially for 6 PRB as subframe 0 and 5 contains PBCH and PSS
signals, so the available REs are reduced.
The eNB scheduler now has this limitation in mind and lowers the MCS.
Change-Id: I0e38fe28002fd68c768cc8dcffcf74f4f190df02
this was causing failed tests because to achieve QAM64 rates both
eNB and UE need to support it and have it activated.

It is easier to traverse debugging logs if the CTRL request and response
IDs are globally unique across all programs and tests. Before this, we
were using 0 almost everywhere.
(This is not strictly needed for correctness, since each CTRL client has
its own request ID scope; just we open fairly many separate CTRL clients
all the time in our tests.)

The pattern to use 'with' to keep a CTRL connection open adds indents to
every test script that wants to avoid multiple reconnections to the
CTRL. Instead, keeping a single open connection that is cleaned up on
{bsc,msc,nitb} object cleanup ensures that a) the program started up
successfully and opened a CTRL port, b) always has a CTRL open without
having to worry about it and c) keeps test scripts less
complex/indented/crufted.
(These are all current users of the OsmoCtrl API.)
Change-Id: I53fedbe569c5ccbc4b1a17dafe1f8d1bb8200b24
CTRL interface interaction was mostly inherited from the first legacy
implementation of osmo-gsm-tester, and it was a pain to look at from the
start. Now, while I'm close to the topic, I want this to improve:
Properly match a GET_REPLY/SET_REPLY to a sent GET/SET by the message
ID.
Completely drop the do_get() and do_set(), which were not useful for
correct handling of the CTRL request and response messaging. The API to
use by callers is set_var(), get_var()/get_int_var() and get_trap().
These call the internal _sendrecv() (or for TRAP only _recv())
functions. Make it so that tese work both on an already connected
OsmoCtrl, as well as one that needs to establish a (short) connection,
so that both are trivially possible:
# one CTRL connection stays open
with OsmoCtrl(...) as ctrl:
ctrl.get_var('var1')
ctrl.get_var('var2')
ctrl.get_var('var3')
and
# get_var() opens a connection, does the GET and closes again
OsmoCtrl(...).get_var('var1')
Do away with doubling the instances OsmoCtrl and e.g. OsmoBscCtrl.
Rather make OsmoBscCtrl a child class of OsmoCtrl, which means that we
no longer have bsc.ctrl().ctrl(), just bsc.ctrl().
Have VERB_* constants instead of dup'd strings.
Apply to / simplify all callers of OsmoCtrl.
Some of these changes are similar to recently added OsmoVty.
Change-Id: Id561e5a55d8057a997a8ec9e7fa6f94840194df1
Implicitly use distinct IDs for CTRL commands. This is a prerequisite
for matching GET_REPLY IDs to GET IDs, to correctly handle CTRL
responses without counting on being lucky.
Rather use 'use_id' as var name instead of overloading the 'id' keyword.

The blocking CTRL socket must have a timeout.
So far we have always been reading from the CTRL socket in a blocking
way. So far we are always lucky that we are indeed getting a response to
receive. Should the CTRL interface ever fail to answer, the tester would
be stuck infinitely.

Remove ARFCNs as a concept from resource pool, assign a fixed ARFCN to
each BTS and TRX in the resource pools.
Using ARFCNs on specific bands as resources was an idea that is hard to
implement, because specific BTS dictate selection of bands which
influences which ARFCNs can be picked. That means reserving ARFCN
resources is only possible after reserving specific BTS resources, but
the tester is currently not capable of such two-stage resolution.
Writing handover tests, I got the problem that both BTS in a scenario
attempt to use the same ARFCN.
The by far easiest solution is to assign one fixed ARFCN to each BTS and
TRX. If ever needed, a scenario modifier can still configure different
ARFCNs.
(Due to uncertainty about OC2G operation stability, I prefer to leave
OC2G on ARFCN 50, as it happened to end up being configured before this
patch.)
