At the moment your hardware is okay.

5: Is there some thing changed the use method? I found some different on klever install directory. There is only one linux 3.14 project job on the new version,
[cid:_Foxmail.1 at 0aa56111-8751-5c6c-c81d-60e1e71122ea]



There was a bug (https://forge.ispras.ru/issues/9581), so that Klever populated development jobs in the production mode. Now everything is okay.


Could you help me to solve it?? Thanks!!!

I need more data to help you, since provided one does not explain me anything.

In ideal, it would be great, if you will provide me a temporary access to your server, namely, to http://server_ip_or_name:8998. But that can be impossible.

So, let's you share more data. Please, provide me a screenshot of the job page from where you could see the exception

Besides, try to solve the verification job with development settings (this is accessible at the job start decision page). Then at the job page you should click on decision status, e.g. "Failed", and there should be a log. Please, provide it to me.

Best regards,
Evgeny

Hi youyan,

it seems, you did not pay an attention to my note:

... Most important is your hardware. I hope that it meets https://klever.readthedocs.io/en/latest/deploy.html#hardware-requirements.<https://klever.readthedocs.io/en/latest/deploy.html#hardware-requirements.>

Klever needs computational resources not only for solving verification jobs (with help of Klever Core which you tried to configure), but for solving verification tasks by verification back-ends like CPAchecker. The latter needs much more CPU time and RAM. RAM is limited strictly unlike CPU time by your hardware. Of course you can edit file "tasks.json" presented at the job page (you should go to Job -> Edit for that), but with small values there you can obtain bad verification results.

So, for experiments you can specify less RAM in "tasks.json", but for production I recommend to use more powerful machine.

Hi youyan,
29.03.2019, 04:37, "黄有焱" <huangyy at landicorp.com<mailto:huangyy at landicorp.com>>:
  hi Evgeny Novikov
  Thanking for your reply and help. Fellow is my enviroment and some issues info.
  1: what version of Klever did you install?
   I fetch klever by git clone --recursive https://forge.ispras.ru/git/klever.git,<https://forge.ispras.ru/git/klever.git,so> so it should on master branch.<https://forge.ispras.ru/git/klever.git, so%20it%20should%20on%20master%20branch.>

I see that in general everything is okay.

BTW, I detected a small but crucial issue in master that you will encounter if you will follow the standard workflow. So, I recommend you to update Klever according to documentation. It should be pretty simple and fast.

  2:Collect the appropriate build base, met some error,attachment is the error log
[cid:_Foxmail.1 at 6b6a1c1f-d005-06aa-6535-f07ef4e7720e]


The first issue is known, it is not critical at all. Perhaps, you just won't be able to verify some particular Linux kernel modules, but most likely you are not interested in verification of all modules.

We will investigate reasons of the second and the third issues (https://github.com/17451k/clade/issues/89). We did not see them before. I suggest that running clade-all with sudo will help to overcome them, but it is just a temporary workaround. I am not sure, but the issue seems to be rather critical, so, something can fail later.

3: My pc enviroment:
[cid:_Foxmail.1 at 8a017769-7cf0-4811-ec68-66a4b8fd79fa]
If I should switch to debian 9?

I think that there you will have the same issue. Most important is your hardware. I hope that it meets https://klever.readthedocs.io/en/latest/deploy.html#hardware-requirements.

4: I found that Klever 2.0 is only support x86 and x86_64.
[cid:_Foxmail.1 at c7fb2f22-ede3-b266-9148-b13adc7f99ec]
Our projects are arm platform. Is there klever version can support arm platform on your hand? If have,can your release to me?


No, we did not have it and we need to update and to test several things since we made these experiments several years ago and everything moved ahead too much.

In Klever there are several add-ons<https://klever.readthedocs.io/en/latest/deploy-common.html#klever-addons> that care about a target software architecture more or less. Just CIF should be re-built appropriately as an ARM cross-compiler. Other add-ons need just specific configurations. Nevertheless, in general there can be some unexpected issues.

Thus, I recommend you to try to build and to verify your modules built for x86_64 if this is possible of course.

Dear youyan,

we welcome your goal and we will be glad to help you.

First of all, I would like to know what version of Klever did you install? The latest version from the master branch should work pretty well, but there can be some new tricky issues regarding Klever 2.0 that is marked by tag v2.0 in the Git repository.

Unfortunately, either in Klever 2.0 or in the latest version of Klever we have not any user documentation except for deployment instructions. If your deployment was successful, you should be able to open localhost:8998 in your browser. There you can sign in with user manager (the password is the same as username) that has very many permissions except for user management. For the latter there is user admin (the password is the same as username).

After successful signing in, please, check that in Menu -> Schedulers the Klever scheduler is healthy.

Then you can try to start solution of verification job Linux 3.14. And you should see an error like "FileExistsError: Build base "/home/admin/klever-bin/klever/build bases/linux-3.14.79" is not a directory".

Below, please, find my previous answer regarding preparing sources for verification:

Now we do not provide source code of target programs to Klever directly, but prepare so called build bases in advance. To do that you need to do the following actions on a machine where you deployed Klever 2.0:

1. Get sources of required versions of the Linux kernel, e.g.:
$ wget https://cdn.kernel.org/pub/linux/kernel/v3.x/linux-3.14.79.tar.xz
$ tar -xf linux-3.14.79.tar.xz
$ cd linux-3.14.79

2. Configure the Linux kernel appropriately, e.g.:
$ make allmodconfig

3. Build the Linux kernel intercepting build commands, e.g.:
$ clade-intercept make -j16
(this can take several dozens of minutes)

4. Collect the appropriate build base:
PATH=$PATH:$KLEVER_DEPLOY_DIR/klever-addons/CIF/ clade-all -p linux_kernel cmds.txt
(this can take several hours, and unfortunately there can be some crucial errors somewhere in the middle since we did not test it much with new versions of the Linux kernel, but I hope that we can workaround all issues)


5. Execute this magic command:
echo "[\"$(readlink -f .)\"]" > "clade/Storage/working source trees.json"


You don't need to execute the last step for the latest Klever from the master branch.


Your build base is ready. It is placed into directory clade. You can rename this directory to something that you like more, e.g. to linux-3.14.79. Then you need to either specify an absolute path to this directory in job.json (option "build base") or install it using an appropriate deployment configuration and deployment scripts.

For new versions of the Linux kernel you will need to patch source files in subdirectory "Storage" within the build base.

After all you should be able to solve job "Linux 3.14".

If you will meet some issues, please, report them to us. We will try to solve or workaround them together.

At last, you can read and contribute Further development of Klever in favor of verification of the Linux kernel<https://docs.google.com/document/d/11e7cDzRqx0nO1UBcM75l6MS28zRBJUicXdNiReEpDKI/edit>, that describes many different issues with Klever.

Dear huangyy,

Thank you for the report.
We have updated the link to the LDV image:
http://sed.ispras.ru/fmprac/data/ldv-docker-0.8.tar.gz

But as you may know, we switched from LDV Tools to the next generation toolset that is called KLEVER:
https://forge.ispras.ru/projects/klever

A draft of documentation for KLEVER is available here:
https://klever.readthedocs.io/en/latest/
