RHBA-2018:3499 - Bug Fix Advisory

Topic

Updated openvswitch packages that fix several bugs are now available in Fast Datapath for Red Hat Enterprise Linux 7.

Description

Open vSwitch provides standard network bridging functions and support for the OpenFlow protocol for remote per-flow control of traffic.

This update fixes the following bug:

• Previously, when the ovs-vswitchd service restarting, an error displayed with many open files. With this update, the number of sockets opened by ovs-vswitchd are decreased, and the described problem no longer occurs. (BZ#1634015)

In addition, this update adds the following enhancements:

• With this update, the pmd-rxq-assign configuration has been added to Poll Mode Drivers (PMDs) cores. This allows a user to select a round-robin assignment. (BZ#1631797)
• With this update, a support for the Dynamic Host Configuration Protocol (DHCP) option, 252, has been added in Open Virtual Network (OVN) Native DHCP. (BZ#1641740)
• With this update, Open vSwitch (OVS) binaries are linked statically to increase performance when Data Plane Development Kit (DPDK) is used. (BZ#1643478)

Users of openvswitch are advised to upgrade to these updated packages, which fix this bug and add these enhancements.
