attr bug fix update

Updated attr packages that fix multiple bugs are now available for Red Hat
Enterprise Linux 6.

The attr packages provide extended attributes, which can be used to store system
objects like capabilities of executables and access control lists, as well as
user objects.

This update fixes the following bugs:

* Prior to this update, the setfattr utility could not restore the original
values of the attributes when the "getfattr -e text" or "getfattr
--encoding=text" command was used to dump attributes with embedded null
characters. This update fixes the encoding of these values in getfattr to
prevent information loss. (BZ#651119)

* Prior to this update, the getfattr utility followed symbolic links to
directories even if the "-h" or "--no-dereference" option was specified.
Additionally, the description in the getfattr(1) man page that related to this
functionality was misleading. This update fixes getfattr with the "-h" option so
that it no longer follows the symbolic links and the related content of the
getfattr(1) man page is now correct. (BZ#665049)

* Prior to this update, the getfattr utility did not return a non-zero exit code
when an attribute specified in the "getfattr" command did not exist. This update
fixes getfattr so that it now returns a non-zero exit code when an attribute
does not exist. (BZ#665050)

* Prior to this update, supported methods for encoding values of the extended
attributes were not properly described in the setfattr(1) man page. This update
adds the appropriate descriptions of the encoding methods to the setfattr(1) man
page. (BZ#674870)

* Prior to this update, the project web page address as stated in the package
specification did not reflect the change of the upstream project web page
address. This update corrects the project web page address in the package
specification. (BZ#702639)

* Prior to this update, the attr library was built without support for
read-only relocations (RELRO) flags. With this update, the library is
now built with partial RELRO support. (BZ#727307)

All users of attr are advised to upgrade to these updated packages, which fix
these bugs.

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red
