Subject: [PATCH v8 00/12] Network support for Landlock

Hi,
This is a new V8 patch related to Landlock LSM network confinement.
It is based on the landlock's -next branch on top of v6.1-rc1 kernel version:
https://git.kernel.org/pub/scm/linux/kernel/git/mic/linux.git/log/?h=next

It brings refactoring of previous patch version V7.
Mostly there are minor fixes of logic and typos.

All test were run in QEMU evironment and compiled with
 -static flag.
 1. network_test: 18/18 tests passed.
 2. base_test: 7/7 tests passed.
 3. fs_test: 78/78 tests passed.
 4. ptrace_test: 8/8 tests passed.
