The loaded Landlock eBPF programs can be triggered by a seccomp filter
returning RET_LANDLOCK. In addition, a cookie (16-bit value) can be passed from
a seccomp filter to eBPF programs. This allow flexible security policies
between seccomp and Landlock.

Is this still up to date, or was that removed in v3?

I forgot to remove this part. In this v4 series, as describe in the
(small) patch 11/18, a Landlock rule cannot be triggered by a seccomp
filter. So there is no more RET_LANDLOCK nor cookie.
