device-mapper bug fix and enhancement update

Updated device-mapper packages that fix several bugs and add various
enhancements are now available for Red Hat Enterprise Linux 5.

The device-mapper packages provide a library required by logical volume
management utilities such as LVM2 and dmraid.

The device-mapper package has been upgraded to upstream version 1.02.63, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#680958) Those enhancements include:

* Unlink failure in the remove_lockfile() function in dmeventd is now checked
for.

* Inactive table query support is now supported when using the Red Hat
Enterprise Linux 5.7 kernel. The "dmsetup table --inactive" command can be run
to view the contents of the inactive table instead of the live one, which is the
default.

* The dm_task_secure_data() function has been added to libdevmapper to wipe the
ioctl buffers in the kernel.

* A new "-R" option has been added to restart dmeventd without loss of state.

These updated device-mapper packages provide fixes for the following bugs:

* Previously, booting encrypted devices which used Multi-Level Security (MLS)
enforcing mode failed with this error message:

/dev/mapper/temporary-cryptsetup-977: lsetfilecon failed: Operation not
permitted

The problem occurred when cryptsetup created a device node and relabeled it
using the lsetfilecon() function instead of using the setfscreatecon() function.
This has been fixed and devices which used MLS enforcing mode now boot
successfully. (BZ#584884)

* When installing the kernel-2.6.18 packages, this error message was logged to
the /root/install.log file: "matchpathcon failed: No such file or directory".
The problem has been fixed and this error message is no longer logged to
install.log with this update. (BZ#695374)

* This update fixes a conflict which occurred when lvm2 and the device mapper
debuginfo packages were installed together. (BZ#701715)

Users are advised to upgrade to these updated device-mapper packages, which
resolve these bugs and add these enhancements.

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