RHBA-2011:0520 - lldpad bug fix and enhancement update

Synopsis

lldpad bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

Topic

An updated lldpad package that fixes multiple bugs and adds one enhancement is now available for Red Hat Enterprise Linux 6.

Description

The lldpad package provides the Linux user space daemon and configuration tool for Intel's Link Layer Discovery Protocol (LLDP) agent with Enhanced Ethernet support.

This update fixes the following bugs:

• Previously, lldpad did not initiate a Data Center Bridging Exchange (DCBX) negotiation if a link down netlink event message (nlmsg) was dropped or lost. Due to this lack, DCBX could not negotiate and Fibre Channel over Ethernet (FCoE) did not login to the fabric in this case. This update resolves this problem. Now, lldpad successfully initiates a Data Center Bridging Exchange (DCBX). (BZ#631587)

• Previously, lldpad could not be upgraded or removed on systems which had lldpad packages for both Intel P6 and Intel 64 simultaneously installed. As a workaround, this update removes such packages with the command rpm -e --noscripts. (BZ#647833)

• Previously, non-default priorities for FCoE did not correctly work, because lldpad handled application type-length-values (TLV) incorrectly. With this update, non-default priorities work as expected. (BZ#694671)

• Previously, lldpad did under certain circumstances not correctly synchronize with peers on link events. Due to this issue, users had to manually reset the link or lldpad. This update resolves the synchronization issue. Now, synchronization with peers on link events works as expected. (BZ#694925)

This update also adds the following enhancement:

• The lldpad package has been upgraded to upstream version 0.9.41, which builds on the new kernel interface and adds support for 802.1Qbg Edge Virtual Bridging, netlink, and libvirt, as well as a new, flexible build process. (BZ#675076)

All lldpad users are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.
