--- Comment #9 from Mateusz Guzik <mjg@FreeBSD.org> ---
Now this is sketchy. So when you openat/whatever with an absolute path caps=
 are
not getting populated and the dir fd is not logged by audit. On the other h=
and
the fd is not used in the lookup, so making its caps affect the outcome any=
way
may not be the right thing to do here.

There is also potential crappery with startdir (used by nfs).

I guess restructuring is the way to go here.

Note there is a much-needed cleanup to do here anyway: audit code *duplicat=
es*
the logic used to determine starting vnodes.
