  Merge tag 'landlock_v34' of ... jmorris/linux-security

Landlock provides for unprivileged application sandboxing. The goal of
Landlock is to enable to restrict ambient rights (e.g. global filesystem
access) for a set of processes. Landlock is inspired by seccomp-bpf but
instead of filtering syscalls and their raw arguments, a Landlock rule
can restrict the use of kernel objects like file hierarchies, according
to the kernel semantic.
