Add generic and read-only tests for 6 pseudo filesystems to make sure they have a consistent inode management, which is required for Landlock's file hierarchy identification: - tmpfs - ramfs - cgroup2 - proc - sysfs Update related kernel configuration to support these new filesystems, remove useless CONFIG_SECURITY_PATH, and sort all entries. If these filesystems are not supported by the kernel running tests, the related tests are skipped. Expanding variants, this adds 25 new tests for layout3_fs: - tag_inode_dir_parent - tag_inode_dir_mnt - tag_inode_dir_child - tag_inode_dir_file - release_inodes Test coverage for security/landlock with kernel debug code: - 94.7% of 835 lines according to gcc/gcov-12 - 93.0% of 852 lines according to gcc/gcov-13 Test coverage for security/landlock without kernel debug code: - 95.5% of 624 lines according to gcc/gcov-12 - 93.1% of 641 lines according to gcc/gcov-13 Link: https://lore.kernel.org/r/20230612191430.339153-6-mic@digikod.net Signed-off-by: Mickaël Salaün <mic@digikod.net>
