Upstream patch on top of 8.22:
http://lists.gnu.org/archive/html/coreutils/2014-01/msg00012.html
Stripped down to the relevant part: NEWS and THANKS.in chunks removed.
Original NEWS entry:
cp -a again sets the correct SELinux context for existing directories in
the destination. Previously it set the context of an existing directory
to that of its last copied descendent.
[bug introduced in coreutils-8.22]

Subject: [PATCH] copy: fix SELinux context preservation for existing
directories
* src/copy.c (copy_internal): Use the global process context
to set the context of existing directories before they're populated.
This is more consistent with the new directory case, and fixes
a bug for existing directories where we erroneously set the
context to the last copied descendent, rather than to that of
the source directory itself.
* tests/cp/cp-a-selinux.sh: Add a test for this case.
