RHBA-2013:0423 - Bug Fix Advisory
Synopsis
trace-cmd bug fix and enhancement update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated trace-cmd packages that fix two bugs and add one enhancement are now
available for Red Hat Enterprise Linux 6.
Description
The trace-cmd packages contain a command-line tool that interfaces with the
ftrace utility in the kernel.
This update fixes the following bugs:
- The trace-cmd extract command read a buffer multiple times even after an EOF
condition. Consequently, the output of the trace-cmd command contained duplicate
data. With this update, the trace-cmd utility has been modified to respect the
EOF condition and avoid duplication of data in its output. (BZ#746656)
- When using the latency tracer, the start_threads() function was not called.
Calling the stop_threads() function without first calling start_threads() caused
the trace-cmd record command to terminate with a segmentation fault because PIDs
were not initialized. Consequently, the trace.dat file was not generated. With
this update, stop_threads() is not called unless start_threads() is called
first. As a result, the segmentation fault no longer occurs. (BZ#879792)
In addition, this update adds the following enhancement:
- Previously, the trace-cmd record command was able to filter ftrace data based
on a single PID only. With this update, multiple PIDs can be specified by using
the "-P" option. (BZ#838746)
Users of trace-cmd are advised to upgrade to these updated packages, which fix
these bugs and add this enhancement.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
