Add io_uring tests

[l0kod]

io_uring is a complex interface growing quickly that can lead to critical security issues and bypass of security checks. Current Landlock's tests don't check with io_uring operations.

It would be good to extend Landlock's tests using relevant io_uring's operations (e.g. IORING_OP_OPENAT, IORING_OP_CONNECT).

hi I am Maha from outreachy, can you guide me about this issue

[l0kod]

Hi! The goal is to add new tests to these test files.

[maha-sachin]

@l0kod, Thank you for your assistance! can you help me to assign this issue? , I will start working on it and make the necessary changes.

[l0kod]

I'm assigning this issue to you. Please regularly update it with your progress. This doesn't need to be long but just enough to make sure you are not blocked.

You can add the io_uring command on which you are working on. Other people interested to add new tests could complete this list and work together.

@l0kod, I appreciate the opportunity to contribute. I'll start working on it right away and will provide regular updates on my progress.

@Madhupatel08 please read the Outreachy's kernel development documentation first. Your PR doesn't help with this issue, there is nothing specific to Landlock.

Hi Maha - Are you intending to be an applicant with Linux Kernel Outreachy this round? Please drop me a note if so. Thanks! (I'm the kernel coordinator for Outreachy)

[maha-sachin]

Hi @AlisonSchofield, Glad to hear from you.
I am interested in becoming an applicant. What might be the best way to reach out to you?

[maha-sachin]

@l0kod, @AlisonSchofield , I'm excited about the opportunity to contribute to the Linux Kernel project. However, I am using a macOS Apple Silicon device, and I understand that the project setup requires Linux, which is typically more conducive to working with the kernel. To address this, I'm in the process of arranging to obtain Ubuntu OS through my city employment service. Once I have it set up, I'll be fully equipped to dive into the project requirements.

Thank you for your understanding and support.

Hi, I would like to work on this issue. I have already made contributions to drivers/staging and have one patch accepted and a couple patches with the acked-by tags. Can I please get this issue assigned to me so I can start working on It?
Thank you.

[l0kod]

Hi @MissTipo! Yes, you can start working on this. We like tests and everyone can add new ones. Moreover, you are indeed following the Outreachy rules and already sent a lot of patches.

For now, we can have several assignees. We'll see how it goes with the first patches for this task.

[l0kod]

For reference: the related patch.

[l0kod]

I guess nobody is working on this task anymore.

It would be great to also have a test for the IORING_OP_SOCKET operation when Socket access-control is applied.
