RHBA-2013:1127 - device-mapper-multipath bug fix update

Synopsis

device-mapper-multipath bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated device-mapper-multipath packages that fix one bug are now available for Red Hat Enterprise Linux 6.

Description

The device-mapper-multipath packages provide tools for managing multipath devices using the device-mapper multipath kernel module.

This update fixes the following bug:

  • Prior to this update, Device Mapper Multipath did not check for NULL pointers before dereferencing them in the sysfs functions. As a result, the multipathd daemon could crash if a multipath device was resized while a path device was being removed. With this update, Device Mapper Multipath checks for NULL pointers in sysfs functions and no longer crashes when a multipath device is resized at the same time as a path device is removed. (BZ#988704)

Users of device-mapper-multipath are advised to upgrade to these updated packages, which fix this bug.

Solution

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

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258
