RHBA-2011:0743 - Bug Fix Advisory

Topic

An updated fcoe-utils package that fixes several bugs and adds various
enhancements is now available for Red Hat Enterprise Linux 6.

Description

The fcoe-utils package allows users to use Fibre Channel over Ethernet (FCoE).
The package contains the fcoeadm command line tool for configuring FCoE
interfaces, and the fcoemon service to configure DCB (Data Center Bridging)
Ethernet QoS filters.

The fcoe-utils package has been upgraded to upstream version 1.0.18, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#672453, BZ#691613)

This update fixes the following bugs:

• Previously, in a particular setup with multipath and FCoE services, the system

sometimes became unresponsive during shutdown or reboot, and a hard reboot was
required to get the system back up. Now, an additional FCoE root filesystem
check has been added to the init script and the system no longer hangs during
reboot or shutdown in this scenario. (BZ#645917)

• Sometimes, FCoE devices are not discovered immediately by the system. As a

consequence, some FCoE partitions were previously not automounted after a boot.
With this update, the FCoE init script waits for a certain amount of time (65
seconds by default), which is enough for most FCoE partitions to be discovered
and mounted during the boot. (BZ#658076)

• Running the fcoeadm tool without the FCoE stack loaded caused the fcoeadm tool

to terminate with a backtrace when it tried to free an unallocated pointer. With
this update, only successfully allocated pointers are freed and the fcoeadm tool
returns a proper error message otherwise. (BZ#678487)

• After VLAN discovery was tried unsuccessfully 10 times, the default FCoE

driver for an interface was used instead of the preferred one. With this update,
VLAN discovery is retried indefinitely and FCoE interfaces are now created only
upon VLAN discovery, with proper drivers. (BZ#689631)

• For several fcoe-utils executables, there were minor inconsistencies in the

documentation between their command help output and their man pages. With this
update, the documentation has been updated and the man pages and help output are
now consistent. (BZ#623567)

• The vconfig package had been marked for removal from the distribution, but the

fcoe-utils package required it at runtime. With this update, this dependency has
been removed in favor of the iproute package. (BZ#645796)

• When an FCoE VLAN interface was restarted, the FCoE interface was not

re-enabled after the VLAN interface was brought up again. This bug has been
fixed and the FCoE interface is now automatically enabled after the VLAN
interface is brought up. (BZ#680578)

This update adds the following enhancement:

• With this update, the fcoe-utils package introduces a new SUPPORTED_DRIVERS

configuration option to list all the low-level drivers that can potentially
claim a network device. The package also uses the new sysfs module path
introduced by the Red Hat Enterprise Linux 6.1 kernel update. (BZ#669211)

Users of fcoe-utils are advised to upgrade to this updated package, which fixes
these bugs and adds these enhancements.
