It is based on the latest landlock-wip branch on top of v5.19-rc2: https://git.kernel.org/pub/scm/linux/kernel/git/mic/linux.git/log/?h=landlock-wip It brings refactoring of previous patch version V5: - Fixes some logic errors and typos. - Adds additional FIXTURE_VARIANT and FIXTURE_VARIANT_ADD helpers to support both ip4 and ip6 families and shorten seltests' code. - Makes TCP sockets confinement support optional in sandboxer demo. - Formats the code with clang-format-14 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: 59/59 tests passed. 4. ptrace_test: 8/8 tests passed. Still have issue with base_test were compiled without -static flag (landlock-wip branch without network support) 1. base_test: 6/7 tests passed.
