RHBA-2011:0799 - Bug Fix Advisory

Topic

An updated libhbalinux package that fixes various bugs is now available for Red
Hat Enterprise Linux 6.

Description

The libhbalinux library is a vendor library utilized by fcoe-utils. The
libhbaapi library provides programmatic access to the libhbalinux library. This
library can retrieve adapter information with the assistance of libpciaaccess.

This updated libhbalinux package includes fixes for the following bugs:

• Creating an FCoE (Fibre Channel over Ethernet) interface, by executing the

"fceoadm -c [interface]" command, and shortly after the creation executing the
"fcoeadm -i" command (which displays information about FCoE instances), resulted
in a segmentation fault due to a NULL pointer dereference. This update fixes
this issue and a segmentation fault no longer occurs in the aforementioned case.
(BZ#690014)

• After upgrading the libhbalinux package, the "fcoeadm -i" command (which shows

information about FCoE instances) printed an error message. With this update,
the "fcoeadm -i" command has been fixed, and no longer returns an error message.

All users of libhbalinux are advised to upgrade to this updated package, which
resolves these issues.

Solution

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

Note: upgrading from the 1.0.10-2 and earlier versions to a newer version
removes the library reference from the /etc/hba.conf file. This causes libHBA
applications (such as FCoE) to malfunction and is a known issue. Reinstalling
the new version after the upgrade resolves this problem.

This update is available via Red Hat Network. Details on how to use the Red Hat
Network to apply this update are available at
