--- Comment #4 from Niall Douglas <s_bugzi...@nedprod.com> --- It turns out that I was wrong about there being no method of retrieving a canonical path for an open file descriptor on FreeBSD. There in fact is, and it is called KERN_PROC_FILEDESC. Unfortunately, KERN_PROC_FILEDESC is broken for regular files, but not directories where it works perfectly - even tracking renames and deletions with ease. The attached test case and its output shows the broken behaviour: 1. Files opened with O_CREAT never get a path. Creating the file, closing it and opening it again gets the file descriptor its path. 2. As soon as the process does its first rename() all the paths for all the regular file descriptors get reset to null, but not directory file descriptors. 3. Directory file descriptors work correctly. This was tested on FreeBSD 10.1 with ZFS on root. Other filing systems may vary.
