RHBA-2011:1760 - Bug Fix Advisory

Topic

Updated pciutils packages that fix a bug and add an enhancement are now
available for Red Hat Enterprise Linux 6.

Description

The pciutils package contains various utilities for inspecting and manipulating
devices connected to the PCI bus.

This update fixes the following bug:

• Previously, in an attempt to free data structures from memory via the

pci_free_cap() function, the "glibc detected *** double free or corruption
(!prev):" error message was returned and the operation failed. A patch has been
provided to address this issue and freeing system resources now works properly.
(BZ#740630)

This update adds the following enhancement:

• With this update, TPH (Transaction Processing Hints) and LTR (Latency

Tolerance Reporting) reporting capabilities have been added to the pciutils
package to support the PCI Express 3.0 standard. (BZ#742223)

All pciutils users should upgrade to these updated packages, which fix this bug
and add this enhancement.
