Hi,

This series is a proof of concept to fill some missing part of seccomp as the
ability to check syscall argument pointers or creating more dynamic security
policies. The goal of this new stackable Linux Security Module (LSM) called
Landlock is to allow any process, including unprivileged ones, to create
powerful security sandboxes comparable to the Seatbelt/XNU Sandbox or the
OpenBSD Pledge. This kind of sandbox help to mitigate the security impact of
bugs or unexpected/malicious behaviors in userland applications.

Maybe I'm missing an obvious description, but: do you have a
description of the eBPF API to landlock?  What function do you
provide, when is it called, what functions can it call, what does the
fancy new arraymap do, etc?
