RHBA-2015:1321 - Bug Fix Advisory

Topic

Updated linuxptp packages that fix several bugs and add various enhancements are
now available for Red Hat Enterprise Linux 6.

Description

The linuxptp packages provide Precision Time Protocol (PTP) implementation for
Linux according to IEEE standard 1588 for Linux. The dual design goals are to
provide a robust implementation of the standard and to use the most relevant and
modern Application Programming Interfaces (API) offered by the Linux kernel.

The linuxptp packages have been upgraded to upstream version 1.5, which provides
a number of bug fixes and enhancements over the previous version. (BZ#1190222)

In addition, this update adds the following enhancement:

• This update adds support for failover between Precision Time Protocol (PTP)

domains or Network Time Protocol (NTP) sources. The system is now able to fall
back to an alternate time source if PTP becomes unavailable, or maintain PTP
synchronization in the event of Network Interface Controller (NIC) failure by
using another NIC in the system. (BZ#1085584)

Users of linuxptp are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.
