Hi all,
Our lava instance has been upgraded from 2019.03 to 2019.07 today.
Some of our teams need extra job context variables to be allowed, so I
added in /etc/lava-server/settings.conf the following parameter, as
described in one of your releases:
EXTRA_CONTEXT_VARIABLE: ["variable_1", "variable_2", "variable_3"]
It seems to work, but when I want to submit a job, sometimes I get the
warning "extra key not allowed" and if I hit the button "validate" many
times I finally get "valid definition". But sometimes I get "valid
definition" directly.
Is it a known issue?
Best regards,
Axel
Hello,
if the prompt is "# " without more characters then in the lava job
definition you have to put "# ".
In fact, this won't work well because this string can be seen on other
places (like kernel logs).
The only solution here would be to change the prompt of the root filesystem
to make it a bit more unique.

Hello Lava Users,
The target on which I am trying to run tests from LAVA has # prompt after
login.
As specified in Documentation
https://lava.collabora.co.uk/static/docs/v2/actions-boot.html?highlight=pro…
- boot:
prompts:
# escape the brackets to ensure that the prompt does not match
# kernel debug lines which may mention initramfs
- '\(initramfs\)'
in the job definition I am including -
boot:
.....
failure_retry: 4
prompts:
- '\(# \)'
But in the job execution log getting "*auto-login-action: Wait for
prompt ['\\(# \\)', 'Login incorrect', 'Login timed out'] (timeout
00:07:52)*".
Also if we want to debug while running the job which will be the best
possible approach to follow.
In the Documentation got information on "Debugging Django issues"
which states two settings are required
in/etc/lava-server/settings.conf
- "DEBUG": true,
- "USE_DEBUG_TOOLBAR": true,
Thanks,
Hemanth.
Hello Denis,
in the timeouts dictionary, you can specify a connections dictionary.
So something like this should work:
timeouts:
connections:
overlay-unpack:
minutes: 10
See
https://docs.lavasoftware.org/lava/actions-timeout.html#connection-timeout

Hi,
I'm trying to write a test definition that contains a repeat block (boot / test) as described in the help section.
However the repeat block gives me the syntax error:
"Invalid definition: extra keys not allowed @ data['actions'][2]['repeat']"
I then tried using https://git.lavasoftware.org/lava/lava/blob/master/lava_dispatcher/tests/sa… as an example and I get the same error message with the repeat.
Is this something that is expected to work? I would like to use repeat blocks for some soak tests that I am writing.
Pete

Hello,
I am working with Denis HUMEAU for STMicroelectronics.
I have a problem to perform several reboot with LAVA job when I am using an image with requested login.
I do not understand why 'root' login is sent to device under test when the prompt is received (lines 941, 942, 943, 944 in job_43624.log file). 'root' login should be sent only when a 'login_prompt' is received (like in lines 696, 697, 698, 699, 701, 702 in job_43624.log file).
Could you help me to solve this problem, please ?
Regards,

Hello everyone,
I have the following LAVA setup:
LAVA server - 1 LAVA worker - 16 DUTs
The LAVA server and the LAVA worker are located in my company network (172.20.0.0/16).
The DUTs are connected to the LAVA worker in a local network (192.168.20.0/24).
Thus, the DUTs are not accessible from outside the worker.
What is a good way to allow for hacking sessions to a DUT (let's say 192.168.20.247) from the company network?
I can think of the following solutions:
1. Use SSH forwarding on lava-worker:
ssh -g -L 50000:localhost:22 -N root(a)192.168.20.247
2. Forward the SSH port via netcat on lava-worker:
nc -l -p 50000 -c "nc 192.168.20.247 22"
3. Forward the SSH port via iptables on lava-worker:
iptables -t nat -A PREROUTING -p tcp --dport 50000 -j DNAT --to 192.168.20.247:22
All of these make the device accessible via "ssh -p 50000 root@lava-worker" from the company network. So far, so good.
However, in an ideal world this forwarding would be active only during the hacking session, so that in normal test jobs the DUT is not accessible.
Is there a way to achieve this? Does anyone have experience with such a scenario? How do you handle DUT access for hacking sessions?
Mit freundlichen Grüßen / Best regards

Hello LAVA experts,
I need your help for a more complex test we would need to run.
We'd like to test a gateway node that talks to remote sensors.
* the gateway node is a Cortex-A like (E.g.: RPi3) board
* sensors might be a mixture of Cortex-M (non-Linux) and Cortex-A (Linux) devices
* communication between the gateway node and sensors might happen with different protocols: bluetooth, wifi, lora, zigbee.
* besides the gateway node, we need to control every sensor and be able to provision and to power cycle them.
We are pretty confident on running tests on single boards (with and without interaction with LXC containers) but as the above example is more complex we need some guidance on how this can be achieved with LAVA.
The main question mark we have is how LAVA interacts with Cortex-M devices, especially for their deployment.
Does anyone of you have a similar scenario? What are the main challenges? How complicated and/or robust to run something similar with LAVA?
Can you point us to documentation, examples?
Any help is very much appreciated.
Thanks!
