Hi Ingo,
Please consider pulling.
But please test the bison/flex thing, it was a bit tricky to make it
work with/without O=, and also to make it work on at least RHEL6.2, Fedora 14
and Ubuntu 10.04 LTS.
I know that bison barfs on Fedora 8, but left the fix for later.

----------------------------------------------------------------
perf/urgent fixes:
. Check for SIGINT in more loops, allowing tools such as 'perf report' to
react faster to control+C.
. Fix objdump line parsing offset validation in the annotate code,
from Adrian Hunter.
. Fix buildid cache handling of kallsyms with kcore, from Adrian Hunter.
. Fix compile with libelf without get_phdrnum, from Adrian Hunter.
. Sharpen the libaudit dependencies test, refusing to build with older
libraries that doesn't have all the functions used by 'perf trace", fix
from Ingo Molnar.
. Fill in new definitions for madvise()/mmap() flags to fix the build in
older systems, from Ingo Molnar.
. Fix old GCC build error in older systems in the kallsyms parsing code in
trace-event-parse.c, from Ingo Molnar.
. Ignore DWARF declaration tags, allowing, for instance, that the
$ perf probe -L getname
command succeeds in showing the source code for the 'getname' kernel
function, telling in which lines probes can be inserted, fix from
Masami Hiramatsu.
. Fix linux/magic.h related build breakage in some systems, fix from
Vinson Lee.

Looks like the failure is caused by arm64 uapi/asm/sigcontext.h, which
includes linux/types.h while other archs not.
Current perl consider this problem:
http://perl5.git.perl.org/perl.git/commit/bd31be4baa3ee68abdb92c0db3200efe0fad903b
However there are users which use old version of perl.
This patch includes stdbool.h before Context.xs and define HAS_BOOL to
prevent perl'e headers define its own 'bool'. Code is learn from perl's
git tree.

Don't use the ins's ->sncprintf() if the parsing failed.
For example, this fixes the display of "imul %edx". Without this patch:
| imul (null),(null)
After this patch:
| imul %edx

From: Namhyung Kim <namhyung@kernel.org>
When a dso contains multiple symbols which have same name, current
dso__find_symbol_by_name() only finds an one of them and there's no way
to get the all symbols without going through the rbtree.
So make symbols__find_by_name() return the first entry with the given
name and the next patch in this series will provide a way to iterate
from there, by the name ordered rb_tree, till a suitable symbol is
found.

From: Namhyung Kim <namhyung@kernel.org>
The find_probe_trace_events_from_map() searches matching symbol from a
map (so from a backing dso). For uprobes, it'll create a new map (and
dso) and loads it using a filter. It's a little bit inefficient in that
it'll read out the symbol table everytime but works well anyway.
For kprobes however, it'll reuse existing kernel map which might be
loaded before. In this case map__load() just returns with no result.
It makes kprobes always failed to find symbol even if it exists in the
map (dso).
To fix it, use map__find_symbol_by_name() instead. It'll load a map
with full symbols and sorts them by name. It needs to search sibing
nodes since there can be multiple (local) symbols with same name.

The commit dfef99cd0b2c ("perf probe: Use ref_reloc_sym based address
instead of the symbol name") converts kprobes to use ref_reloc_sym (i.e.
_stext) and offset instead of using symbol's name directly. So on my
system, adding do_fork ends up with like below:
$ sudo perf probe -v --add do_fork%return
probe-definition(0): do_fork%return
symbol:do_fork file:(null) line:0 offset:0 return:1 lazy:(null)
0 arguments
Looking at the vmlinux_path (7 entries long)
Using /lib/modules/3.17.6-1-ARCH/build/vmlinux for symbols
Could not open debuginfo. Try to use symbols.
Opening /sys/kernel/debug/tracing/kprobe_events write=1
Added new event:
Writing event: r:probe/do_fork _stext+456136
Failed to write event: Invalid argument
Error: Failed to add events. Reason: Operation not permitted (Code: -1)
As you can see, the do_fork was translated to _stext+456136. This was
because to support (local) symbols that have same name. But the problem
is that kretprobe requires to be inserted at function start point so it
simply checks whether it's called with offset 0. And if not, it'll
return with -EINVAL. You can see it with dmesg.
$ dmesg | tail -1
[125621.764103] Return probe must be used without offset.
So we need to use the symbol name instead of ref_reloc_sym in case of
return probes.

Hi Ingo,
So here it is the fixes in perf-core-for-mingo-4.14-20170912, as
requested, plus one last minute fix from Milian Wolff that helps with
using perf as an AppImage[1].
- Arnaldo

perf stat: Wait for the correct child (2017-09-12 12:49:13 -0300)
----------------------------------------------------------------
perf/urgent fixes:
- Fix TUI progress bar when delta from new total from that of the
previous update is greater than the progress "step" (screen width
progress bar block)) (Jiri Olsa)
- Make tools/lib/api make DEBUG=1 build use -D_FORTIFY_SOURCE=2 not
to cripple debuginfo, just like tools/perf/ does (Jiri Olsa)
- Avoid leaking the 'perf.data' file to workloads started from the
'perf record' command line by using the O_CLOEXEC open flag (Jiri Olsa)
- Fix building when libunwind's 'unwind.h' file is present in the
include path, clashing with tools/perf/util/unwind.h (Milian Wolff)
- Check per .perfconfig section entry flag, not just per section (Taeung Song)
- Support running perf binaries with a dash in their name, needed to
run perf as an AppImage (Milian Wolff)
- Wait for the right child by using waitpid() when running workloads
from 'perf stat', also to fix using perf as an AppImage (Milian Wolff)

Test results:
The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.
Several are cross builds, the ones with -x-ARCH, and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf
commands with a variety of command line event specifications to then
intercept the sys_perf_event syscall to check that the perf_event_attr
fields are set up as expected, among a variety of other unit tests.
The 'perf test' also runs shell scripts exercising the tools, checking
if they affect the system in certain ways, like setting up kprobes and
uprobes, request callchains for well known programs and check that they
are the expected ones, see if 'perf trace' beautifies system call
arguments correctly, etc.
Additionally, a new set of tests, script based, runs the tools in a live system,
setting probes in place that then gets used by 'perf trace', with its output
compared against expected results.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

perf record: Combine some auxtrace initialization into a single function (2018-03-06 12:03:39 -0300)
----------------------------------------------------------------
perf/urgent fixes:
- Be more robust when drawing arrows in the annotation TUI, avoiding a
segfault when jump instructions have as a target addresses in functions
other that the one currently being annotated. The full fix will come in
the following days, when jumping to other functions will work as call
instructions (Arnaldo Carvalho de Melo)
- Prevent auxtrace_queues__process_index() from queuing AUX area data for
decoding when the --no-itrace option has been used (Adrian Hunter)
- Sync copy of kvm UAPI headers and x86's cpufeatures.h (Arnaldo Carvalho de Melo)
- Fix 'perf stat' CVS output format for non-supported counters (Ilya Pronin)
- Fix crash in 'perf record|perf report' pipe mode (Jiri Olsa)
- Fix annoying 'perf top' overwrite fallback message on older kernels (Kan Liang)
- Fix the usage on the 'perf kallsyms' man page (Sangwon Hong)

Test results:
The first ones are container (docker) based builds of tools/perf with and
without libelf support. Where clang is available, it is also used to build
perf with/without libelf.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Pulled, thanks a lot Arnaldo!
Note that there's a new, minor conflict between perf/core and perf/urgent - I
resolved it and merged perf/urgent into perf/core, please double check my
resolution.
