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,
This is a new V11 patch related to Landlock LSM network confinement.
It is based on the landlock's -next branch on top of v6.2-rc3+ kernel version:
https://git.kernel.org/pub/scm/linux/kernel/git/mic/linux.git/log/?h=next
It brings refactoring of previous patch version V10.
Mostly there are fixes of logic and typos, refactoring some selftests.
All test were run in QEMU evironment and compiled with
-static flag.
1. network_test: 36/36 tests passed.
2. base_test: 7/7 tests passed.
3. fs_test: 78/78 tests passed.
4. ptrace_test: 8/8 tests passed.
