RHBA-2011:1712 - Bug Fix Advisory

Topic

An updated oprofile package that fixes one bug and adds two enhancements is now
available for Red Hat Enterprise Linux 6.

Description

OProfile is a system-wide profiler for Linux systems. The profiling runs
transparently in the background and profile data can be collected at any time.
OProfile uses the hardware performance counters provided on many processors, and
can use the Real Time Clock (RTC) for profiling on processors without counters.

This update fixes the following bug:

• Previously, OProfile could encounter a buffer overrun in the OProfile daemon.

This update modifes oprofiled so that OProfile now checks and reports if the
filename is too large for the buffer. (BZ#717860)

This update also adds the following enhancements:

• Previously, the OProfile profiler did not provide the performance monitoring

events for the Intel Sandy Bridge processor. This update provides the files for
the Intel Sandy Bridge processor specific performance events and adds the code
to identify Intel Sandy Bridge processors. Now, OProfile provides Intel Sandy
Bridge specific events. (BZ#696565)

• Previously, the OProfile profiler did not identify some Intel Westmere

processors causing OProfile to use the fallback Intel Architected events. Now,
OProfile provides Intel Westmere specific events for Intel Westmere-EX
processors (model 0x2f). (BZ#695851)

All OProfile users are advised to upgrade to this updated package which fixes
this bug and adds these enhancements.
