Hi Ingo,

The following changes since commit 82819ffb42fb45197bacf3223191deca31d3eb91:

  perf probe: Try to use symbol table if searching debug info failed (2015-08-21 12:57:20 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Fix segfault using 'perf script --show-mmap-events', affects
  only current perf/core (Adrian Hunter).

- /proc/kcore requires CAP_SYS_RAWIO message too noisy, make it
  debug only (Adrian Hunter)

- Fix Intel PT timestamp handling (Adrian Hunter)

- Add Intel BTS support, with a call-graph script to show it and
  PT in use in a GUI using 'perf script' python scripting with
  postgresql and Qt (Adrian Hunter)

- Add checks for returned EVENT_ERROR type in libtraceevent, fixing
  a bug that surfaced on arm64 systems (Dean Nelson)

- Fallback to using kallsyms when libdw fails to handle a vmlinux file,
  that can happen, for instance, when perf is statically linked and
  then libdw fails to load libebl_{arch}.so (Wang Nan)

Infrastructure:

- Initialize reference counts in map__clone() (Arnaldo Carvalho de Melo)

#1211236 — [PATCH 4/9] tools lib traceevent: Add checks for returned EVENT_ERROR type

FromArnaldo Carvalho de Melo <acme@kernel.org>
Date2015-08-21 18:20 +0200
Subject[PATCH 4/9] tools lib traceevent: Add checks for returned EVENT_ERROR type
Message-ID<pZXcT-kI-53@gated-at.bofh.it>
In reply to#1211235
From: Dean Nelson <dnelson@redhat.com>

Running the following perf-stat command on an arm64 system produces the
following result...

  [root@aarch64 ~]# perf stat -e kmem:mm_page_alloc -a sleep 1
    Warning: [kmem:mm_page_alloc] function sizeof not defined
    Warning: Error: expected type 4 but read 0
  Segmentation fault
  [root@aarch64 ~]#

The second warning was a result of the first warning not stopping
processing after it detected the issue.

That is, code that found the issue reported the first problem, but
because it did not exit out of the functions smoothly, it caused the
other warning to appear and not only that, it later caused the SIGSEGV.

#1211238 — [PATCH 3/9] perf tools: Fix Intel PT timestamp handling

FromArnaldo Carvalho de Melo <acme@kernel.org>
Date2015-08-21 18:20 +0200
Subject[PATCH 3/9] perf tools: Fix Intel PT timestamp handling
Message-ID<pZXcU-kI-67@gated-at.bofh.it>
In reply to#1211235
From: Adrian Hunter <adrian.hunter@intel.com>

Events that don't sample the timestamp have a timestamp value of -1.

Intel PT processing wasn't taking that into account.

This is particularly noticeable with Intel BTS because timestamps are
not requested by default.

Then, if the conversion of -1 to TSC results in a small number, the
processing is unaffected.

However if the conversion results in a big number, then the data is
processed prematurely before relevant sideband data like mmap events,
which in turn results in samples with unknown dsos.

Commiter note:

Since BTS wasn't upstream, I split the patch to fold the BTS part with
the patch introducing it, to avoid having this bug in the commit
history. PT was already upstream, so this patch contains that part.

#1211239 — [PATCH 8/9] perf tools: Initialize reference counts in map__clone()

FromArnaldo Carvalho de Melo <acme@kernel.org>
Date2015-08-21 18:20 +0200
Subject[PATCH 8/9] perf tools: Initialize reference counts in map__clone()
Message-ID<pZXcU-kI-69@gated-at.bofh.it>
In reply to#1211235
From: Arnaldo Carvalho de Melo <acme@redhat.com>

Map clone was written before we introduced reference counts for
maps and dsos, so all that was needed was just a copy and then we
would insert it into the new map_groups instance.

Fix it by, after copying, initializing the map->refcnt, grabbing
a struct dso refcount and resetting pointers that may be used
to determine if a map, when deleted, is in a rb_tree.

#1211240 — [PATCH 1/9] perf script: Fix segfault using --show-mmap-events

FromArnaldo Carvalho de Melo <acme@kernel.org>
Date2015-08-21 18:20 +0200
Subject[PATCH 1/9] perf script: Fix segfault using --show-mmap-events
Message-ID<pZXcU-kI-77@gated-at.bofh.it>
In reply to#1211235
From: Adrian Hunter <adrian.hunter@intel.com>

Patch "perf script: Don't assume evsel position of tracking events"
changed 'perf script' to use 'perf_evlist__id2evsel()'. That results
in a segfault if there is more than 1 event and there are
synthesized mmap events e.g.

	$ perf record -e cycles,instructions -p$$ sleep 1
	$ perf script --show-mmap-events
	Segmentation fault (core dumped)

That happens because these synthesized events have an 'id' of zero
which does not match any 'evsel'.

Currently, these synthesized events use the sample type of the first
evsel.

Change 'perf_evlist__id2evsel()' to reflect that which also makes
it consistent with 'perf_evlist__event2evsel()'.
