Hi, I am trying to write a test to conditionally extract files from a zip file for use in some scripts, e.g. unzip the file, copy/move the files I need out, remove the zip file and directory created from unzipping it. However, the zip file size exceeds the disk space of the DUT. I have considered doing something like a MultiNode job, where the DUT is booted as well as a QEMU instance, and the file is downloaded and extracted on the QEMU and moved onto the DUT, but I would prefer not to do that if possible. Is there any way to download the zip file mid-test to the worker instead, extract the files I need, and move them onto the DUT? Ideally no modifications to the code of LAVA, but if that is necessary then I can figure out an interim solution and come back to it later. Regards, Michael

LAVA LDAP mirror groups

by Michael Peddie

Hi, I am trying to get LDAP working in my LAVA instance, and have managed to get logging into it working. The issue comes when I try to use Django's MIRROR_GROUPS setting. I am already aware that it is not built into LAVA to be configurable, and I have already taken steps to add the relevant lines in lava_server/settings/common.py to make it work (initialize to None, values.get() in the update method, then run eval on the value in the LDAP if section), but it still won't work. All other required settings are clearly working just fine, and I can even set USER_FLAGS_BY_GROUP just fine, but I would prefer to mirror certain groups that users are members of and assign permissions to the groups. Do I need to pre-create the groups before logging in to LAVA or am I missing something else/doing something wrong?

How to start docker container with privileged mode which used for postprocessing artifacts

by Sai Ashrith Sathujoda

We have a requirement for some test cases that the artifacts need to be modified (negative scenario) in order to verify some scenarios. we are currently using postprocess under deploy action for this purpose. As of part postprocess, we need to mount partitions of disk image and make some changes based on the requirement. However, we are unable to mount the partitions using losetup command. docker: image: debian:bookworm steps: - apt-get update - loop_dev=$(losetup -P -f --show image.wic) - echo $loop_dev The job failed with below error, losetup -P -f --show image.wic losetup: cannot find an unused loop device It looks like the docker container needs root privileges. It works when we run locally with "privileged:true". Is there any way we can pass "privileged: true" option to docker image through LAVA job definitions? Any inputs regarding this matter are highly appreciated.

How to verify secure boot negative test cases

by shivanand.kunijadar＠toshiba-tsip.com

Hello, I'm trying to verify secure boot on LAVA lab, I've verified the positive case of secure boot and confirmed the secure boot is enabled from the boot logs (kernel-start-message = "EFI stub: UEFI Secure Boot is enabled."). Next, I would like to verify the negative test case as well by tampering the secure boot image where I expect the image boot shall fail. Is there way in LAVA to make the job complete(e.g. waiting for specific message in boot logs like "Can't find image information. ") even though the image fails to boot on the DUT? Ref. https://lava.ciplatform.org/scheduler/job/1236667#L81

Securing LAVA Setup

by Michael Peddie

Hi, I have been looking into how to secure LAVA, as so far it's just been learning how it works. There's the obvious http/https stuff, and in the documentation mentions firewalls for remote workers (which we'll be using anyways). We already have things in place for physical security and plans on how to improve, so no worries there. Is there anything not covered in the documentation that should be considered and how could we go about putting that into place? Best regards, Michael

What does the gdb boot method do?

by 叶轩杨

I saw a file 'lava-dispatcher/actions/boot/gdb.py' in the LAVA source code, which seems to define a gdb method in action->boot. But I didn't find a description of it in the LAVA documentation. The document I checked is `https://docs.lavasoftware.org/lava/actions-boot.html?highlight=boot#boot-action-reference`. Reading the source code may lead to some misunderstandings and is time-consuming. I hope someone who knows its function can explain to me what this new method does. Thank you very much!

How to add custom data in the metadata field of notify callback json?

by 叶轩杨

I want to add some key:value pair in metadata of json that POST by notification of job, but I can not figure it out. I had tried add metadata in job defination and test defination, but the back json did not have my data in metadata field, it was just a []. Then I read the lava source code, I find the metadata data are produced by method `get_metadata_dict()` in class `TestJob`. This method is called at method `create_job_data` in class `TestJob`, it creates the json data which will post to callback url. `get_metadata_dict()` check whether there is an attribute `testdata`, but I can not find the place where this attribute‘s assignment. Could someone give me a way to do this? Thanks you very much! 🙏
