Yes, I checked your namei code in the meantime, and the absolute path in indeed checked for. It is just sad we still do the fd_getfile/fd_putfile for nothing if it is an absolute path. In fact I think it would make simplier and less error-prone code if NDAT would take a file descriptor instead of a vnode. fd_getfile/fd_putfile would be done only once in our codebase in namei(). I understand it is not be desirable regarding how the kernel is layered, though. -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz m...@netbsd.org
