In the Linux kernel, the following vulnerability has been resolved:
nfs4setupreaddir(): insufficient locking for ->dparent->dinode dereferencing
Theoretically it's an oopsable race, but I don't believe one can manage to hit it on real hardware; might become doable on a KVM, but it still won't be easy to attack.
Anyway, it's easy to deal with - since xdrencodehyper() is just a call of putunalignedbe64(), we can put that under ->d_lock and be done with that.
