Red Hat Product Errata RHBA-2015:1389 - Bug Fix Advisory

RHBA-2015:1389 - Bug Fix Advisory

  • Overview
  • Updated Packages

Synopsis

corosync bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated corosync packages that fix one bug and add two enhancements are now
available for Red Hat Enterprise Linux 6.

Description

The corosync packages provide the Corosync Cluster Engine and C Application
Programming Interfaces (APIs) for Red Hat Enterprise Linux cluster software.

This update fixes the following bug:

  • When the corosync utility was configured with the IPv6 network and packet
    fragmentation was disabled on the Network Interface Controller (NIC) or switch,
    no packets were delivered. This update implements a correct calculation of the
    data fragment size, and packets are delivered as intended. (BZ#1136431)

In addition, this update adds the following enhancements:

  • Earlier when using the UDP unicast (UDPU) protocol, all messages were sent to
    all the configured members, instead of being sent to only the active members.
    This makes sense for merge detection messages, otherwise it creates unnecessary
    traffic to missing members and can trigger excessive Address Resolution Protocol
    (ARP) requests on the network. The corosync code has been modified to only send
    messages to the missing members when it is required, otherwise to only send
    messages to the active ring members. Thus, most of the UDPU messages are now
    sent only to the active members with an exception of the messages required for
    proper detection of a merge or a new member (1-2 pkts/sec). (BZ#1163846)
  • With this update, the corosync packages have been modified to test whether the
    network interface has different IP address, port, and IP version when using the
    Redundant Ring Protocol (RRP) mode. Now, corosync properly checks correctness of
    the configuration file and prevents failures when using the RRP mode.
    (BZ#742999)

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

Solution

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