Upstream changelog:

* Noteworthy changes in release 7.3 (2009-05-01) [stable]

** Bug fixes

  cp now diagnoses failure to preserve selinux/xattr attributes when
  --preserve=context,xattr is specified in combination with -a.
  Also, cp no longer suppresses attribute-preservation diagnostics
  when preserving SELinux context was explicitly requested.

  ls now aligns output correctly in the presence of abbreviated month
  names from the locale database that have differing widths.

  ls -v and sort -V now order names like "#.b#" properly

  mv: do not print diagnostics when failing to preserve xattr's on file
  systems without xattr support.

  sort -m no longer segfaults when its output file is also an input file.
  E.g., with this, touch 1; sort -m -o 1 1, sort would segfault.
  [introduced in coreutils-7.2]

** Changes in behavior

  shred, sort, shuf: now use an internal pseudorandom generator by default.
  This is mainly noticable in shred where the 3 random passes it does by
  default should proceed at the speed of the disk.  Previously /dev/urandom
  was used if available, which is relatively slow on GNU/Linux systems.

** Improved robustness

  cp would exit successfully after copying less than the full contents
  of a file larger than ~4000 bytes from a linux-/proc file system to a
  destination file system with a fundamental block size of 4KiB or greater.
  Reading into a 4KiB-or-larger buffer, cp's "read" syscall would return
  a value smaller than 4096, and cp would interpret that as EOF (POSIX
  allows this).  This optimization, now removed, saved 50% of cp's read
  syscalls when copying small files.  Affected linux kernels: at least
  2.6.9 through 2.6.29.
  [the optimization was introduced in coreutils-6.0]

** Portability

  df now pre-mounts automountable directories even with automounters for
  which stat-like syscalls no longer provoke mounting.  Now, df uses open.

  `id -G $USER` now works correctly even on Darwin and NetBSD. Previously it
  would either truncate the group list to 10, or go into an infinite loop,
  due to their non-standard getgrouplist implementations.
  [truncation introduced in coreutils-6.11]
  [infinite loop introduced in coreutils-7.1]
