FreeBSD : FreeBSD -- Cross-mount links between nullfs(5) mounts (b72bad1c-20ed-11e3-be06-000c29ee3065)

Problem Description : The nullfs5 implementation of the VOPLINK9 VFS operation does not check whether the source and target of the link are both in the same nullfs instance. It is therefore possible to create a hardlink from a location in one nullfs instance to a file in another, as long as the...
