Hi Konstantin,
The kernel code looks good. I found some issues in tests and
documentation, and I'm still reviewing the whole patches. In the
meantime, I've pushed it in -next, we'll see how it goes.
We need to have this new code covered by syzkaller. I'll work on that
unless you want to.
Regards,
Mickaël
Hi, Mickaël!
I have never set up syzkaller. Do you have a syzkaller scenario for
Landlock code? I need some hints. I will give it a shot.
Regards,
Konstantin.
