tools lib traceevent kbuffer: Remove extra update to data pointer in PADDING

2015-05-06T19:59:15+00:00

commit c5e691928bf166ac03430e957038b60adba3cf6c upstream.

When a event PADDING is hit (a deleted event that is still in the ring
buffer), translate_data() sets the length of the padding and also updates
the data pointer which is passed back to the caller.

This is unneeded because the caller also updates the data pointer with
the passed back length. translate_data() should not update the pointer,
only set the length.

tools lib traceevent: Fix memory leak in pretty_print()

2014-05-31T20:20:27+00:00

commit de04f8657de9d3351a2d5880f1f7080b23b798cf upstream.

Commit 12e55569a244 "tools lib traceevent: Use helper trace-seq in print
functions like kernel does" added a extra trace_seq helper to process
string arguments like the kernel does it. But the difference between the
kernel and the userspace library is that the kernel's trace_seq structure
has a static allocated buffer. The userspace one has a dynamically
allocated one. It requires a trace_seq_destroy(), otherwise it produces
a nasty memory leak.

perf tools: Fix traceevent plugin path definitions

2014-01-23T18:48:12+00:00

The plugindir_SQ definition contains $(prefix) which is not needed as
the $(libdir) definition already contains prefix in it.  This leads to
the path including an extra prefix in it, e.g. /usr/usr/lib64.

The -DPLUGIN_DIR defintion includes DESTDIR.  This is incorrect, as it
sets the plugin search path to include the value of DESTDIR.  DESTDIR is
a mechanism to install in a non-standard location such as a chroot or an
RPM build root.  In the RPM case, this leads to the search path being
incorrect after the resulting RPM is installed (or in some cases an RPM
build failure).

Remove both of these unnecessary inclusions.
