Hi,
This is a new V10 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 V9.
Mostly there are fixes of logic and typos, adding new tests.

All test were run in QEMU evironment and compiled with
 -static flag.
 1. network_test: 30/30 tests passed.
 2. base_test: 7/7 tests passed.
 3. fs_test: 78/78 tests passed.
 4. ptrace_test: 8/8 tests passed.
