The patch introduces Landlock ABI version 6 and has three types of tests
"and adds three types" ?
that examines different scenarios for abstract unix socket connection:
Not only connection.
1) unix_socket: base tests of the abstract socket scoping mechanism for a landlocked process, same as the ptrace test. 2) optional_scoping: generates three processes with different domains and tests if a process with a non-scoped domain can connect to other processes. 3) unix_sock_special_cases: since the socket's creator credentials are used
"unix_sock_special_cases" seems a bit too generic and is not self-explanatory. What about "outside_socket"?
for scoping sockets, this test examines the cases where the socket's credentials are different from the process using it. Signed-off-by: Tahera Fahimi <redacted> ---
