by Axel Lebourhis

Hi all, I'm facing a pretty frustrating issue when running CTS/VTS with LAVA. I'm using Linaro's tradefed test definition : https://git.linaro.org/qa/test-definitions.git/tree/automated/android/trade… During some runs, the adb connection is lost, leading to incomplete test job. Do you know if this behavior is known and mostly general ? Or is it a bad configuration on my side ? Maybe someone knows some way to keep a reliable adb connection to the target ? Best regards, Axel

What's the difference of lava log feedback & log output on the web page?

by Larry Shen

Sometimes, I can see the lava log feedback to repeat the the lava log output, sometimes cannot. Could you give an example simple inline test, so I can always see some log feedback? Something like: - test: timeout: minutes: 1 definitions: - from: inline name: smoke-case path: inline/test.yaml repository: metadata: format: Lava-Test Test Definition 1.0 name: smoke-case-run description: Run smoke case run: steps: - lava-test-case "Case_001" --shell 'echo "Case001 gstreamer ok";' How could I let ` Case001 gstreamer ok` also been seen in feedback log level?

lava-test-case only handles lower case results strings

by Patryk Mungai Ndungu

Hello, I have recently upgraded from 2018.11 to 2019.03 and have noticed that the results of a lot of the tests I have been running no longer got parsed correctly by LAVA. This was because I was sending the results using upper case results strings. Eg. lava-test-case <test-case> PASS opposed to lava-test-case <test-case> pass This resulted in the following logs in the lava job: Received signal: <TESTCASE> TEST_CASE_ID=ETH_T_001 RESULT=PASS Bad test result: PASS Changing my results parsing script to only send lower case results strings fixed the issue, but was this restriction intended with the upgrade? Kind Regards, Patryk

password change prompt: how to automate?

Error: "deploy stage is missing" in multinode job

by Axel Lebourhis

Hi all, I'm currently trying to make a multinode job for CTS on Android 9. During this job, I need to unlock uboot so I use the "interactive" test action. But when I add it to my job definition, I get an error message during the run : "Nothing to run. Maybe the 'deploy' stage is missing, otherwise this is a bug which should be reported." If I remove the test action with the "interactive" method, I won't get that error. Maybe I'm missing something but I don't get what it could be. You will find attached a test job example which leads to this error. Best regards, Axel

timeouts for deploy vs http-download

by Kevin Hilman

Hello, I'm trying to customize the http-download timeout as documented[1], but I doesn't seem to work. The global deploy time always seems to win. Based on the doc, I did this, I added the following to my job[2] timeouts: actions: http-download: minutes: 15 However, in the job output, you can see that the http-download timeout value is set to 25 min (1500 sec) which is coming from the deploy action timeout. I got the same result when tryin to use timeouts: connections: What am I missing?

Re: [Lava-users] Why make the decision to limit job context in lava master?

by Larry Shen

Thanks, Remi, So, looking forward to your patch which allow admins to extend the white list with a variable in the settings. Regards, Larry From: Remi Duraffort <remi.duraffort(a)linaro.org> Sent: Thursday, May 23, 2019 3:59 PM To: Larry Shen <larry.shen(a)nxp.com> Cc: lava-users(a)lists.lavasoftware.org Subject: [EXT] Re: [Lava-users] Why make the decision to limit job context in lava master? Caution: EXT Email Hello Larry, 1. We mainly have 2 kinds of situations: a) Something like "uboot_ums_flash" which already in linaro lava tree. In the past, this can be overridden by job context. And I guess a lots of other variables which spread every corner of different jinja2 files. Huge I think, I really worried how lava can add so many keys in whitelist... Why do you have to update uboot_ums_flash in the job definition and not in the device dictionary? This sounds more like a device specific information instead of a job definition one. Anyway, having a long list of keys in the white list is not really a problem. This is only a python array, nothing more. b) Something which just used in device jinja2 to control some different command in different situations. I know linaro accept upstreams for device-type, I have no idea if private lab's device jinja2 also useful for other people. Contributions are welcome. A rule of thumb for device-type integration/templates is often: is the device available for purchase by someone outside your company? If yes, then it's a good idea to upstream it. If not, then it's more a case-by-case decision. 2. Sounds you guys will not rollback this commit because security issue. So two suggestions: Sorry no :( a) I don't know how this security issue could impact for an internal lab which not exposed to external internet. Anyway, if possible to add a configure to any settings to let admin to decide if we care this security issue? More details to come later on, but I don't think this is a good idea. b) If a) not easy to do or not accept, if possible this whitelist be stored in database or other persist file, so user can free to add his own keyword to whitelist, then even we will upgrade lava to later new version, we can still remain the keyword setting in the past, meanwhile user still can free to add any keyword to whitelist without upstream again and again for this hard coded whitelist, I don't think this make sense. I'm currently writing down a patch to allow admins to extend the white list with a variable in the settings. Please consider. BTW, as Tim Jaacks said in other thread: this limit not happen in multinode job, is it a bug, so next release we will also have this backdoor closed? I'm fixing this second issue in https://git.lavasoftware.org/lava/lava/merge_requests/547<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgit.lavas…> Thanks for reporting it.

auto_login and minimal boot

by Diego Russo

Hello, In my job definition I have a minimal boot: https://staging.validation.linaro.org/static/docs/v2/actions-boot.html?high… Documentation says "auto-login and transfer_overlay are both supported for this method." But if I add auto_login the schema validation in the submit page will raise a warning: "Valid definition with warnings: extra keys not allowed @ data['actions']['boot']['minimal']" Of course if I take the auto_login out, the validation is green. If I leave the auto_login, it will be used. I think the validation needs to reflect what documentation says. Cheers -- Diego Russo | Staff Software Engineer | Mbed Linux OS ARM Ltd.

Using transfer overlay

by Pete Dyer

Hello, I'm using transfer overlay to get a set of tests onto the target. However I want to untar it into /scratch instead of / because of storage requirements. This I can do quite easily. However the tests are going to try to run from / (e.g. /lava-10473/bin/lava-test-runner /lava-10473/1) Is there a way of running tests from /scratch/lava-10473.... ? Or a way of defining a command to run immediately after the transfer overlay that makes a link between /lava-10473 and /scratch/lava-10473 ? Thanks.

Problems with email notifications

Hi lava-users, my Debian machine running lava-server (2019.04) sends mails via msmtp/msmtp-mta. Mails from cron or apt work fine. But I got no mails from lava.

about multinode api parameter file overwritten

The multinode function of "pass data between devices".Note: "The message data is stored in a cache file which will be overwritten when the next synchronisation call is made. Ensure that your scripts make use of (or copy aside) any MultiNode cache data before calling any other MultiNode API helpers that may clear the cache." Does it mean follow example: roler1: .. steps: - lava-send ipv4 ip=192 - lava-send ipv4 ip=193 .. roler2: step2: - lava-wait ipv4 - ipdata=$(cat /tmp/lava_multi_node_cache.txt | cut -d = -f 2) .. After run, is content of roler2 ipdata 193?

How to handle udev events when lava dispatcher is in a container

by Kumar Gala

In trying to run lava-dispatcher inside a docker container and connect a FRDM-K64F board ran into some issues related to the fact that udev events aren’t seen inside the container since we aren’t typically running systemd/udevd there. I came across this project that will forward udev events from the host to a container that worked pretty well: https://github.com/eiz/udevfw I’ve re-implemented this in python for easier development (added some docker awareness): https://git.lavasoftware.org/galak/docker-compose/blob/lite/contrib/udev-fo… Right now running udev-forward.py is kinda kludgy. Wanted to get input on how people think this should work, should we make a daemon out of it? Should there be some kinda of config file? Do we think we need to filter events (and if so how)? Need to look at support for multicasting (support sending to multiple dispatchers). Where should this live, in docker-compose repo? Other thoughts. - k

I didn't see anything about this mentioned in the release announcement. I guess the apache config needs some update? Thanks! Dan

Hello, as said in the previous email, that's currently not possible to see kernel crashes outside of the boot action. That's something we want to improve. I will soon create an issue in our gitlab instance where you would be able to comment.

Correct way to make device not affect others.

by cnspring2002

I attach a tag on one of my device, and when submit job I will add "tags:" to my job, it's ok. But, when others submit their job with same device-type which same as my device, as they did not specify "tags", they will have chance to run their job on my device. How to avoid it? I want the job not be scheduled to the device which have a tag if the job did not specify any tag. I tried to set the device as private, but then only me can use this device, I have other guys in groupA which want to use the device, while I hae another some guys in groupB which didid not want to use these devices as some modules on the device is not same.

device type alias redesign

by Milosz Wasilewski

Hi, There is an idea of device type 'alias' in LAVA. I don't quite understand what the use case for the current implementation was [1]. I tried using it but it wasn't very useful. My use case is that I need to submit jobs to a device type with different device type name. This is used to align device type naming between different labs in a bigger project (kernelci.org in this case). So the questions I have about current implementation: - is there anyone using current implementation? - if current implementation is used, how much trouble would it cause to change the behaviour? Change in behaviour is quite intrusive and will require database migration. [1] https://master.lavasoftware.org/static/docs/v2/glossary.html#term-alias Regards, milosz

[PATCH] Set systemd test data directory

by Khouloud Touil

In case that 'systemd' is one of the ptest to run and to avoid some test cases failure in the systemd ptest, we need to export the proper directory that contains the needed systemd test data.

lava-os-build

by Frank, Matthias

Hi lava users, I have tested lava-os-build on my ptxdist root images and I got this output: root@MBa6x:/lava-557/bin ./lava-os-build _____ ___ ____ _ |_ _/ _ \\ / ___| _ _ ___| |_ ___ _ __ ___root@MBa6x:/lava-557/bin Maybe it's better to look for other files first, like /etc/os-release (or /usr/lib/os-release) for systemd systems. This file is (more) standardized way to detect with os/build is running by evaluating the keys NAME,PRETTY_NAME etc. What is the exact function of lava-os-build? Only diagnostic purpose to find out with os is running? Does something else rely on lava-os-build? What could break if I change that script?

LAVA Ansible playbooks

by Karsten Tausche

Hi, Are the Ansible playbook for setting up LAVA available somewhere? There is an old migrated issue on GitLab [1] which is closed, but the link to an implementation in there is dead. Is that playbook only internally available for Linaro? Is there anything you could share? It looks like many people are moving to Docker in the moment, but that's not an option for us (at least not for dispatchers), as we need LXC for Android testing.

LAVA Django template caching

by Karsten Tausche

Hi all, The LAVA docs mention that it's possible to enable template caching via settings.conf [1]. However, doing so leads to a key error when starting the LAVA gunicorn server and in `lava-server manage check --deploy`: ... File "/usr/lib/python3/dist-packages/lava_server/settings/distro.py", line 185, in <module> ("django.template.loaders.cached.Loader", TEMPLATES[0]["OPTIONS"]["loaders"]) KeyError: 'loaders' The LAVA git history shows that this dictionary key was removed in commit 6705ec870[2], "Refresh the setting files". Is this just a bug in LAVA, is Django template caching not supported anymore with LAVA, or are other Debian/pip packages required to be installed to enable to cache? I'm currently testing that on Debian buster, which ships Django version 1.11. Cheers, Karsten [1] https://validation.linaro.org/static/docs/v2/advanced-installation.html?hig… [2] https://git.lavasoftware.org/lava/lava/commit/6705ec870c1f30ea0b7f78f05a322…

jobs using notify with tokens, resubmit as different user

by Kevin Hilman

How can you have more than one LAVA user have the same token secret (e.g. for a notify callback.)? Example use case: - LAVA job with notify callbacks using token names - submited as user "bob", token names of "bob" map to actual token secrets - job fails - user "lab-admin" fixes some lab issues, re-submits job - job passes, but callbacks fail because tokens are associated with user "bob" Since the re-submitted job runs as user "lab-admin", the same token names and corresponding secrets don't exist. Naively, user "lab-admin" tries to copy the token secrets from user "bob" keeping the same token names, but this fails saying that "secret already exists". Why can't different users have the same secrets? I haven't looked at the code, but this limitation kind of suggests that the secret itself is the key in the db, which would prevent multiple secrets of the same. Kevin

Build information in metadata

by Frank, Matthias

Hello lava users, I use in a test job linuximage, rootfs and dtb from file server location retrieved via http. These files are nightly build from Jenkins. The file links are static so I can use new images within the same test job definition. Jenkins generates also a build information text file with commit IDs an so on. How can I integrate the content of this file in the job metadata or job result log? Using metadata: build-readme: <link> in the job definition is not possible because the link is stable over different build, but the file content is changing. The DUT has no access to the file location because it is in an isolated network. Is there a way to cat the file content on the worker to metadata or job result? Greetings, Matthias

docker-compose with lava

by Dan Rue

I started playing with the official lava images today and wanted to share my work in progress, in case others are doing something similar or have feedback. My goal is to deploy a lava lab locally. My architecture is a single host (for now) that will host both the lava server and one dispatcher. Once it's all working, I'll start deploying a qemu worker followed by some actual boards (hopefully). So far, I have the following docker-compose.yml: version: '3' services: database: image: postgres:9.6 environment: POSTGRES_USER: lavaserver POSTGRES_PASSWORD: mysecretpassword PGDATA: /var/lib/postgresql/data/pgdata volumes: - ${PWD}/pgdata:/var/lib/postgresql/data/pgdata server: image: lavasoftware/amd64-lava-server:2018.11 ports: - 80:80 volumes: - ${PWD}/etc/lava-server/settings.conf:/etc/lava-server/settings.conf - ${PWD}/etc/lava-server/instance.conf:/etc/lava-server/instance.conf depends_on: - database dispatcher: image: lavasoftware/amd64-lava-dispatcher:2018.11 environment: - "DISPATCHER_HOSTNAME=--hostname=dispatcher.lava.therub.org" - "LOGGER_URL=tcp://server:5555" - "MASTER_URL=tcp://server:5556" With that file, settings.conf, and instance.conf in place, I run 'mkdir pgdata; docker-compose up' and the 3 containers come up and start talking to each other. The only thing exposed to the outside world is lava-server's port 80 at the host's IP, which gives the lava homepage as expected. The first time they come up, the database isn't up fast enough (it has to initialize the first time) and lava-server fails to connect. If you cancel and run again it will connect the second time. A few things to note here. First, it doesn't seem like a persistent DB volume is possible with the existing lava-server container, because the DB is initialized at container build time rather than run-time, so there's not really a way to mount in a volume for the data. Anyway, postgres already solves this. In fact, I found their container documentation and entrypoint interface to be well done, so it may be a nice model to follow: https://hub.docker.com/_/postgres/ The server mostly works as listed above. I copied settings.conf and instance.conf out of the original container and into ./etc/lava-server/ and modified as needed. The dispatcher then runs and points to the server. It's notable that docker-compose by default sets up a docker network, allowing references to "database", "server", "dispatcher" to resolve within the containers. Once up, I ran the following to create my superuser: docker-compose exec server lava-server manage users add --staff --superuser --email dan.rue(a)linaro.org --passwd foo drue Now, for things I've run into and surprises: - When I used a local database, I could log in. With the database in a separate container, I can't. Not sure why yet. - I have the dreaded CSRF problem, which is unlikely to be related to docker, but the two vars in settings.conf didn't seem to help. (I'm terminating https outside of the container context, and then proxying into the container over http) - I was surprised there were no :latest containers published - I was surprised the containers were renamed to include the architecture name was in the container name. My understanding is that's the 'old' way to do it. The better way is to transparently detect arch using manifests. Again, see postgres/ as an example. - my pgdata/ directory gets chown'd when I run postgres container. I see the container has some support for running under a different uid, which I might try. - If the entrypoint of server supported some variables like LAVA_DB_PASSWORD, LAVA_DB_SERVER, SESSION_COOKIE_SECURE, etc, I wouldn't need to mount in things like instance.conf, settings.conf. I pushed my config used here to https://github.com/danrue/lava.home.therub.org. Git clone and then run 'docker-compose up' should just work. Anyway, thanks for the official images! They're a great start and will hopefully really simplify deploying lava. My next step is to debug some of the issues I mentioned above, and then start looking at dispatcher config (hopefully it's just a local volume mount). Dan

AOSP multiple node job

by Chase Qi

Hi, In most cases, we don't need multiple node job as we can control AOSP DUT from lxc via adb over USB. However, here is the use case. CTS/VTS tradefed-shell --shards option supports to split tests and run them on multiple devices in parallel. To leverage the feature in LAVA, we need multinode job, right? And in multinode job, master-node lxc needs access to DUTs from salve nodes via adb over tcpip, right? Karsten shared a job example here[1]. This probably is the most advanced usage of LAVA, and probably also not encouraged? To make it more clear, the connectivity should look like this. master.lxc <----adb over usb----> master.dut master.lxc <----adb over tcpip ---> slave1.dut master.lxc <----adb over tcpip ---> slave2.dut .... I see two options for adb over tcpip. Option #1: WiFi. adb over wifi can be enabled easily by issuing adb cmds from lxc. I am not using it for two reasons. * WiFi isn't reliable for long cts/vts test run. * In Cambridge lab, WiFi sub-network isn't accessible from lxc network. Because of security concerns, there is no plan to change that. Option #2: Wired Ethernet. On devices like hikey, we need to run 'pre-os-command' in boot action to power off OTG port so that USB Ethernet dongle works. Once OTG port is off, lxc has no access to the DUT, then test definition should be executed on DUT, right? I am also having the following problems to do this. * Without context overriding, overlay tarball will be applied to '/system' directory and test job reported "/system/bin/sh: /lava-247856/bin/lava-test-runner: not found"[2]. * With the following job context, LAVA still runs '/lava-24/bin/lava-test-runner /lava-24/0' and it hangs there. It is tested in my local LAVA instance, test job definition and test log attached. Maybe my understanding on the context overriding is wrong, I thought LAVA should execute '/system/lava-24/bin/lava-test-runner /system/lava-24/0' instead. Any suggestions would be appreciated. context: lava_test_sh_cmd: '/system/bin/sh' lava_test_results_dir: '/system/lava-%s' I checked on the DUT directly, '/system/lava-%s' exist, but I cannot really run lava-test-runner. The shebang line seems problematic. --- hacking --- hikey:/system/lava-24/bin # ./lava-test-runner /system/bin/sh: ./lava-test-runner: No such file or directory hikey:/system/lava-24/bin # cat lava-test-runner #!/bin/bash #!/bin/sh .... # /system/bin/sh lava-test-runner lava-test-runner[18]: .: /lava/../bin/lava-common-functions: No such file or directory --- ends --- I had a discussion with Milosz. He proposed the third option which probably will be the most reliable one, but it is not supported in LAVA yet. Here is the idea. Milosz, feel free to explain more. **Option #3**: Add support for accessing to multiple DUTs in single node job. * Physically, we need the DUTs connected via USB cable to the same dispatcher. * In single node job, LAVA needs to add the DUTs specified(somehow) or assigned randomly(lets say both device type and numbers defined) to the same lxc container. Test definitions can take over from here. Is this can be done in LAVA? Can I require the feature? Any suggestions on the possible implementations? Thanks, Chase [1] https://review.linaro.org/#/c/qa/test-definitions/+/29417/4/automated/andro… [2] https://staging.validation.linaro.org/scheduler/job/247856#L1888

How to full validate PSCI

by Lionel DEBIEVE

Dear All, I'm currently trying to check and implement a complete validation of my PSCI solution. The standard behavior for PSCI is to manage shutdown, reset and low power mode. I'm wondering to find the best way to manage it through LAVA. So two questions: - Is there a proper way to check the reboot behavior on a target (soft reboot)? Using shell command is not possible as the is no return from reboot. - Shutdown? I'm wondering to test the shutdown command and trig an automatic wake up after x seconds. My wish is to check that no watchdog occurred during that time (which is the only way to know if the shutdown was properly working). So it will be a similar behavior that the reboot command. Thanks for your support, BR Lionel
