I probably sound like a broken record at this point, but I've not seen
this go into any tip branch, nor is it in Linus' tree.  Hopefully this
gets pulled before 3.7 is released.

Pulled, thanks a lot Arnaldo!

I'll get this to Linus ASAP.

Note: got a conflict with perf/core in tools/perf/Makefile, when 
merging in tip:master. It appeared to me that perf/core already 
included all the changes to BASIC_CFLAGS that perf/urgent 
updated, so I picked the perf/core version.

The merged result seems to work fine but please double check it 
nevertheless.

Thanks,

	Ingo

  from Ananth N Mavinakayanahalli.

. libtraceevent: Remove hard coded include to /usr/local/include in
  Makefile, which causes cross builds to include host header files,
  fix from Jack Mitchell.

. perf record: Use the right target interface for synthesizing
  threads when --cpu/-C option is used, fix from Jiri Olsa.

. Check if -DFORTIFY_SOURCE=2 is allowed, as gcc 4.7.2 defines
  it and then the build is broken when it is redefined in perf,
  fix from Marcin Slusarz.

. Fix build with NO_NEWT=1, that can happen explicitely or when
  the newt-devel package is not installed, from Michael Ellerman.

. perf/POWER7: Create a sysfs format entry for Power7 events, missing
  patch from a patchseries already merged, from Sukadev Bhattiprolu.

. Fix LIBNUMA build with glibc 2.12 and older, from Vinson Lee.

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.

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.

[PATCH 1/8] perf hists: Fix crash in perf_hpp__reset_output_field()

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@kernel.org>

Du Changbin reported crash [1] when calling perf_hpp__reset_output_field()
after unregistering field via perf_hpp__column_unregister().

This ends up in calling following list_del* sequence on
the same format:

  perf_hpp__column_unregister:
    list_del(&format->list);
  perf_hpp__reset_output_field:
    list_del_init(&fmt->list);

where the later list_del_init might touch already freed formats.

Fixing this by replacing list_del() with list_del_init() in
perf_hpp__column_unregister().

[PATCH 2/8] perf hists: Add extra integrity checks to fmt_free()

[Arnaldo Carvalho de Melo]

Make sure the struct perf_hpp_fmt is properly unhooked before we free
it.

[PATCH 3/8] perf tools: Check wether the eBPF file exists in event parsing

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@redhat.com>

Adding the check wether the eBPF file exists, to consider it
as eBPF input file. This way we can differentiate eBPF events
from events that end up with same suffix as eBPF file.

Before:

[PATCH 5/8] perf record: Fix documentation for a inexistent option '-l'

[Arnaldo Carvalho de Melo]

From: Taeung Song <treeze.taeung@gmail.com>

'perf record' had a '-l' option that meant "scale counter values" a very
long time ago, but it currently belongs to 'perf stat' as '-c'.  So
remove it. I found this problem in the below case.

    $ perf record -e cycles -l sleep 3

[PATCH 6/8] perf buildid-list: Fix crash when processing PERF_RECORD_NAMESPACE

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung@kernel.org>

Thomas reported that 'perf buildid-list' gets a SEGFAULT due to NULL
pointer deref when he ran it on a data with namespace events.  It was
because the buildid_id__mark_dso_hit_ops lacks the namespace event
handler and perf_too__fill_default() didn't set it.

  Program received signal SIGSEGV, Segmentation fault.

Fix it by adding a stub event handler for namespace event.

Committer testing:

Further clarifying, plain using 'perf buildid-list' will not end up in a
SEGFAULT when processing a perf.data file with namespace info:

  # perf record -a --namespaces sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 2.024 MB perf.data (1058 samples) ]

  #

It is only when one asks for checking what of those entries actually had
samples, i.e. when we use either -H or --with-hits, that we will process
all the PERF_RECORD_ events, and since tools/perf/builtin-buildid-list.c
neither explicitely set a perf_tool.namespaces() callback nor the
default stub was set that we end up, when processing a
PERF_RECORD_NAMESPACE record, causing a SEGFAULT:

  # perf buildid-list -H
  Segmentation fault (core dumped)
  ^C

[PATCH 7/8] perf xyarray: Fix wrong processing when closing evsel fd

[Arnaldo Carvalho de Melo]

From: Jin Yao <yao.jin@linux.intel.com>

In current xyarray code, xyarray__max_x() returns max_y, and xyarray__max_y()
returns max_x.

It's confusing and for code logic it looks not correct.

Error happens when closing evsel fd. Let's see this scenario:

1. Allocate an fd (pseudo-code)

  perf_evsel__alloc_fd(struct perf_evsel *evsel, int ncpus, int nthreads)
  {
	evsel->fd = xyarray__new(ncpus, nthreads, sizeof(int));
  }

  xyarray__new(int xlen, int ylen, size_t entry_size)
  {
	size_t row_size = ylen * entry_size;
	struct xyarray *xy = zalloc(sizeof(*xy) + xlen * row_size);

	xy->entry_size = entry_size;
	xy->row_size   = row_size;
	xy->entries    = xlen * ylen;
	xy->max_x      = xlen;
	xy->max_y      = ylen;
	......
  }

So max_x is ncpus, max_y is nthreads and row_size = nthreads * 4.

2. Use perf syscall and get the fd

  int perf_evsel__open(struct perf_evsel *evsel, struct cpu_map *cpus,
		     struct thread_map *threads)
  {
	for (cpu = 0; cpu < cpus->nr; cpu++) {

		for (thread = 0; thread < nthreads; thread++) {
			int fd, group_fd;

			fd = sys_perf_event_open(&evsel->attr, pid, cpus->map[cpu],
						 group_fd, flags);

			FD(evsel, cpu, thread) = fd;
	}
  }

  static inline void *xyarray__entry(struct xyarray *xy, int x, int y)
  {
	return &xy->contents[x * xy->row_size + y * xy->entry_size];
  }

These codes don't have issues. The issue happens in the closing of fd.

3. Close fd.

  void perf_evsel__close_fd(struct perf_evsel *evsel)
  {
	int cpu, thread;

	for (cpu = 0; cpu < xyarray__max_x(evsel->fd); cpu++)
		for (thread = 0; thread < xyarray__max_y(evsel->fd); ++thread) {
			close(FD(evsel, cpu, thread));
			FD(evsel, cpu, thread) = -1;
		}
  }

  Since xyarray__max_x() returns max_y (nthreads) and xyarry__max_y()
  returns max_x (ncpus), so above code is actually to be:

        for (cpu = 0; cpu < nthreads; cpu++)
                for (thread = 0; thread < ncpus; ++thread) {
                        close(FD(evsel, cpu, thread));
                        FD(evsel, cpu, thread) = -1;
                }

  It's not correct!

This change is introduced by "475fb533fb7d" ("perf evsel: Fix buffer overflow
while freeing events")

This fix is to let xyarray__max_x() return max_x (ncpus) and
let xyarry__max_y() return max_y (nthreads)

Committer note:

This was also fixed by Ravi Bangoria, who provided the same patch,
noticing the problem with 'perf record':

[PATCH 8/8] perf test shell trace+probe_libc_inet_pton.sh: Be compatible with Debian/Ubuntu

[Arnaldo Carvalho de Melo]

From: Li Zhijian <lizhijian@cn.fujitsu.com>

In debian/ubuntu, libc.so is located at a different place,
/lib/x86_64-linux-gnu/libc-2.23.so, so it outputs like this when testing:

  PING ::1(::1) 56 data bytes
  64 bytes from ::1: icmp_seq=1 ttl=64 time=0.040 ms

  --- ::1 ping statistics ---
  1 packets transmitted, 1 received, 0% packet loss, time 0ms
  rtt min/avg/max/mdev = 0.040/0.040/0.040/0.000 ms
  0.000 probe_libc:inet_pton:(7f0e2db741c0))

  getaddrinfo (/lib/x86_64-linux-gnu/libc-2.23.so)
  [0xffffa9d40f34ff4d] (/bin/ping)

Fix up the libc path to make sure this test works in more OSes.

Committer testing:

When this test fails one can use 'perf test -v', i.e. in verbose mode, where
it'll show the expected backtrace, so, after applying this test:

On Fedora 26:

  # perf test -v ping

[GIT PULL 0/8] perf/urgent fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling,

- Arnaldo
Test results at the end of this message, as usual.

The following changes since commit 9dff0aa95a324e262ffb03f425d00e4751f3294e:

  perf/core: Don't WARN() for impossible ring-buffer sizes (2019-02-04 08:45:25 +0100)

  perf script python: Add Python3 support to tests/attr.py (2019-02-05 10:31:08 -0300)

----------------------------------------------------------------
perf/urgent fixes:

perf trace:

  Arnaldo Carvalho de Melo:

    Fix handling of probe:vfs_getname when the probed routine is
    inlined in multiple places, fixing the collection of the 'filename'
    parameter in open syscalls.

perf test:

  Gustavo A. R. Silva:

    Fix bitwise operator usage in evsel-tp-sched test, which made tat
    test always detect fields as signed.

  Jiri Olsa:

    Filter out hidden symbols from labels, added in systems where the
    annobin plugin is used, such as RHEL8, which, if left in place make
    the DWARF unwind 'perf test' to fail on PPC.

  Tony Jones:

    Fix 'perf_event_attr' tests when building with python3.

perf mem/c2c:

  Ravi Bangoria:

    Fix perf_mem_events on PowerPC.

tools headers UAPI:

  Arnaldo Carvalho de Melo:

    Sync linux/in.h copy from the kernel sources, silencing a perf build warning.

Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

 create mode 100644 tools/perf/arch/powerpc/util/mem-events.c

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

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.

[GIT PULL 0/8] perf/urgent fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, I did a git merge with torvalds/master
late last week to fixup some kernel headers ABI sync warnings, but I had
to cherry pick some csets from my perf/core branch to get the container
builds to all work, so ended up slipping past v5.2, oh well, but here it
is, all containers building ok, I'll now test perf/core to then push
that too.

Best regards,

- Arnaldo

Test results at the end of this message, as usual.

  tools build: Check if gettid() is available before providing helper (2019-07-07 17:53:09 -0300)

----------------------------------------------------------------
perf/urgent fixes:

core:

  Arnaldo Carvalho de Melo:

  - Allow references to thread objects after__machine_exit(), fixing a bug with
    'perf sched lat' where that happens, i.e. after perf_session__delete() we
    still have references to threads that were in a linked list whose head was
    freed in perf_session__delete(), causing a segfault, fix it.

  Jiri Olsa:

  - Do not rely on errno values for precise_ip fallback, fixing the default
    use case for 'perf record' on some AMD servers, when no events are specified
    and we try to use "cycles:P", i.e. with the maximum precision level.

BPF:

  Song Liu:

  - Assign proper ff->ph in perf_event__synthesize_features(), fixing a bug
    when using pipe mode, i.e.  'perf record -o -'.

tools headers:

  Arnaldo Carvalho de Melo:

  - Sync kvm headers with the kernel sources

perf tests:

  Seeteena Thoufeek:

  - Fix record+probe_libc_inet_pton.sh for powerpc64, where without the
    debuginfo package for the 'ping' utility we can't resolve its symbols,
    so admit getting "[unknown]" for that backtrace line.

perf python:

  Arnaldo Carvalho de Melo:

  - Remove -fstack-protector-strong if clang doesn't have it, fixing the build
    with clang on fedora:30, oracleline:7, centos:7.

perf jvmti:

  Jiri Olsa:

  - Address gcc string overflow warning for strncpy()

build:

  Arnaldo Carvalho de Melo:

  - Check if gettid() is available before providing helper, as recent
    versions of glibc started to provide gettid().

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

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.

The '41: BPF filter' 'perf test' entry is being investigated, it
shouldn't be with "Skip" status, some problem with BPF maps.

Hi Ingo,

	As requested I merged tip/perf/core with this branch and now its
available as the perf-urgent-for-mingo-5.3-20190708-2 signed tag, that
has only one extra cset:

  commit 686cbe9e5d88ad639bbe26d963e7d5dafa1c1c28 (HEAD -> perf/urgent, tag: perf-urgent-for-mingo-5.3-20190708-2, acme/perf/urgent, acme.korg/perf/urgent)
  Author: Arnaldo Carvalho de Melo <acme@redhat.com>
  Date:   Mon Jul 8 13:47:14 2019 -0300
  
      tools arch x86: Sync asm/cpufeatures.h with the with the kernel

Best regards,
