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]
