Device node in LXC is not accessible in hacking session

by Tim Jaacks

Hey everyone, I have a problem where a physical hardware device on my worker passed through to an LXC container cannot be read from or written to when I am connected to the LXC in a hacking session via SSH. I have registered the device in my static_info: {% set static_info = [ {"board_id": "GO31472"}, ] %} LAVA starts the LXC and attaches the device to it correctly: start: 2.2 lxc-add-static (timeout 00:04:50) [remote] Adding /dev/ttyUSB16, /dev/serial/by-id/usb-GFL_M_504_G_GO31472-if00-port0, /dev/bus/usb/004/008, /dev/serial/by-path/pci-0000:00:1d.3-usb-0:1:1.0-port0 nice lxc-device -n lxc-remote-10577 add /dev/ttyUSB16 nice lxc-device -n lxc-remote-10577 add /dev/serial/by-id/usb-GFL_M_504_G_GO31472-if00-port0 nice lxc-device -n lxc-remote-10577 add /dev/bus/usb/004/008 nice lxc-device -n lxc-remote-10577 add /dev/serial/by-path/pci-0000:00:1d.3-usb-0:1:1.0-port0 end: 2.2 lxc-add-static (duration 00:00:00) [remote] When I connect to the LXC via SSH using a hacking session, the device is there, but I cannot access it: root@lxc-remote-10577:~# ls -la /dev/ttyUSB16 crw-r--r-- 1 root root 180, 0 Aug 27 11:26 /dev/ttyUSB16 root@lxc-remote-10577:~# cat /dev/ttyUSB16 cat: /dev/ttyUSB16: Operation not permitted However, when I attach to the LXC directly from the worker using "lxc-attach", I can access it: root@lxc-remote-10577:~# ls -la /dev/ttyUSB16 crw-r--r-- 1 root root 180, 0 Aug 27 11:26 /dev/ttyUSB16 root@lxc-remote-10577:~# cat /dev/ttyUSB16 ��^C root@lxc-remote-10577:/# Did anybody else encounter such a problem before?

Creating a multinode job

by Ryan Harkin

Hi folks, I'm struggling to create a working multinode job and wondered if someone could help? Here's the sample job I've submitted to try to get a handle on how multinode works: https://validation.linaro.org/scheduler/job/1963418.1#L1745 The main problem happens when LAVA executes this command on the shell: /lava-1963419/bin/lava-test-runner /lava-1963419/1 But there is no "/lava-1963419/1" directory, so then it can't find lava-common-functions and fails like this because the path is relative to a path that doesn't exist: /lava-1963419/bin/lava-test-runner: line 18: /lava-1963419/1/../bin/lava-common-functions: No such file or directory When I run a similar definition on a single node, it uses zero for the lava sub-dir, not 1, and it works: https://validation.linaro.org/scheduler/job/1963236#L2065 I tried to work out what was running here, to see if I could debug the scripts to work out where the "1" comes from. I cloned the LAVA repo and I cannot see the script "environment", and the lava-test-runner sources lava-common-functions from line 16, not 18. So now I'm curious where LAVA gets its scripts from. Another minor point, I'm following the instructions on this link: https://docs.lavasoftware.org/lava/writing-multinode.html And there are some dead links in there, eg. https://docs.lavasoftware.org/lava/examples/test-jobs/first-multinode-job.y… https://docs.lavasoftware.org/lava/examples/test-jobs/second-multinode-job.… https://docs.lavasoftware.org/lava/examples/test-jobs/bbb-lxc-ssh-guest.yaml Thanks, Ryan.

Lava dispatcher compatible question.

by David

Hello, all, Recently I heard from somebody said, lava will drop stretch support from 2020.01 release, I didn't find related information, is it true? I also want to know if I remain on stretch, but still use 2019.12 release just for slave, but maybe later just upgrade master to for example 2020.06 release on buster. Will 2019.12 slave on stretch be compatible with 2020.06(Just a example version) master on buster? Will you promise it? Best Regards, David

lavacli cannot fetch big logs.

by Larry Shen

Hi, there, We have one job to do some stress test, the final log is about 270MB. We use `lavacli -i production jobs logs --raw 30686` to fetch the log, it gives me next: ``` $ time lavacli -i production jobs logs --raw 30686 /usr/lib/python3/dist-packages/lavacli/__init__.py:101: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe.

docker dispatcher qemu mount problem since 2019.11

by Dan Rue

I tried updating my lava-docker-compose repo to the latest but hit a problem mounting the overlay filesystem in qemu as of 2019.11 (2019.10 and earlier works, 2019.11 and later do not). To reproduce, clone https://github.com/danrue/lava-docker-compose/ and run "make"; observe the qemu health-check time out. The health check job can be found at https://github.com/danrue/lava-docker-compose/blob/master/server-overlay/et… The problem seems to occur when it tries to mount the overlay filesystem for the test job. I see in the release notes that the containers moved to buster in 2019.11 - related? Raw output below. Thanks, Dan / # mkdir /lava-2 mkdir /lava-2 mount /dev/disk/by-uuid/16786250-75bd-4703-9d57-7cfa618c725e -t ext2 /lava-2 / # mount /dev/disk/by-uuid/16786250-75bd-4703-9d57-7cfa618c725e -t ext2 /lava-2 mount /dev/disk/by-uuid/16786250-75bd-4703-9d57-7cfa618c725e -t ext2 /lava-2 mount: mounting /dev/disk/by-uuid/16786250-75bd-4703-9d57-7cfa618c725e on /lava-2 failed: No such file or directory ls -la /lava-2/bin/lava-test-runner / # ls -la /lava-2/bin/lava-test-runner ls -la /lava-2/bin/lava-test-runner ls: /lava-2/bin/lava-test-runner: No such file or directory Using /lava-2 export SHELL=/bin/sh / # export SHELL=/bin/sh export SHELL=/bin/sh . /lava-2/environment / # . /lava-2/environment . /lava-2/environment /bin/sh: .: can't open '/lava-2/environment' /lava-2/bin/lava-test-runner /lava-2/0 / # /lava-2/bin/lava-test-runner /lava-2/0 Test shell timeout: 10s (minimum of the action and connection timeout) /lava-2/bin/lava-test-runner /lava-2/0 /bin/sh: /lava-2/bin/lava-test-runner: not found
