  perf bpf: Fix NULL return handling in bpf__prepare_load() (2018-05-16 
10:01:55 -0300)


perf/core improvements and fixes:

- Add '-e intel_pt//u' test to the 'parse-events' 'perf test' entry,
  to help avoiding regressions in the events parser such as one
  that caused a revert in v4.17-rc (Arnaldo Carvalho de Melo)

- Fix NULL return handling in bpf__prepare_load() (YueHaibing)

- Warn about 'perf buildid-cache --purge-all' failures (Ravi Bangoria)

- Add infrastructure to help in writing eBPF C programs to be used
  with '-e name.c' type events in tools such as 'record' and 'trace',
  with headers for common constructs and an examples directory that
  will get populated as we add more such helpers and the 'perf bpf'
  branch that Jiri Olsa has been working on (Arnaldo Carvalho de Melo)

- Handle uncore event aliases in small groups properly (Kan Liang)

- Use the "_stest" symbol to identify the kernel map when loading kcore (Adrian

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, 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

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.

[GIT PULL 00/11] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

Please consider pulling,

- Arnaldo

Build news:

Now the 16.04-x-armhf and 16.04-x-powerpc64 cross build docker images have libz
and libelf cross built from sources, so that we can cover cross build testing
more of the codebase.

In those images objtool is not built, as checking powerpc and arm binaries is
not supported, so trying to build it will end up in linker errors.

Yeah, I noticed that, that is a compat one (the non-compat ones are
already in sync), which is something 'perf trace' needs to support but
can't right now due to raw_syscalls:sys_{enter,exit} limitations, so not
that important right now, will fix it anyway to remove the warning,

Thanks!

So, here is a new pull req, removing the following patch, due to that
segfault you noticed while testing 'perf top' on an ubuntu system:
 
> He Kuang (2):

The new tag is perf-core-for-mingo-20160520.

Kuang, Ingo proposed the patch below to fix the problem he noticed
(notice the 'dso && ' part, as __dsos__find() may return NULL), but he
had several other issues with code touched by this patch, I'll try to
address those, please check the patch below and resubmit.

  perf tools: Set buildid dir under symfs when --symfs is provided (2016-05-19 
19:04:36 -0300)


perf/core improvements and fixes:

User visible:

- We should not use the current value of the kernel.perf_event_max_stack as the
  default value for --max-stack in tools that can process perf.data files, they
  will only match if that sysctl wasn't changed from its default value at the
  time the perf.data file was recorded, fix it.

  This fixes a bug where a 'perf record -a --call-graph dwarf ; perf report'
  produces a glibc invalid free backtrace (Arnaldo Carvalho de Melo)

- Provide a better warning when running 'perf trace' on a system where the
  kernel.kptr_restrict is set to 1, similar to the one produced by 'perf 
record',
  noticed on ubuntu 16.04 where this is the default kptr_restrict setting.
  (Arnaldo Carvalho de Melo)

- Fix ordering of instructions in the annotation code, noticed when annotating
  ARM binaries, now that table is auto-ordered at first use, to avoid more such
  problems (Chris Ryder)

- Fix searching the vdso image to support cross-platform analysis (He Kuang)

- Set buildid dir under symfs when --symfs is provided (He Kuang)

- Fix the 'exit_group()' syscall output in 'perf trace' (Arnaldo Carvalho de 
Melo)

- Only auto set call-graph to "dwarf" in 'perf trace' when syscalls are being
  traced (Arnaldo Carvalho de Melo)

Signed-off-by: Arnaldo Carvalho de Melo 


Arnaldo Carvalho de Melo (7):

  perf trace: Warn when trying to resolve kernel addresses with 
kptr_restrict=1

  perf trace: Move futex_op beautifier to tools/perf/trace/beauty/ (2016-05-06 
13:00:59 -0300)


perf/core improvements and fixes:

User visible:

- Fix ordering of kernel/user entries in 'caller' mode, where the kernel and
  user parts were being correctly inverted but kept in place wrt each other,
  i.e. 'callee' (k1, k2, u3, u4) became 'caller' (k2, k1, u4, u3) when it
  should be 'caller' (u4, u3, k2, k1) (Chris Phlipot)

- In 'perf trace' don't print the raw arg syscall args for a syscall that has
  no arguments, like gettid(). This was happening because just checking if
  the syscall args list is NULL may mean that there are no args (e.g.: gettid)
  or that there is no tracepoint info (e.g.: clone) (Arnaldo Carvalho de Melo)

- Add extra output of counter values with 'perf stat -vv' (Andi Kleen)

Infrastructure:

- Expose callchain db export via the python API (Chris Phlipot)

Code reorganization:

- Move some more syscall arg beautifiers from the 'perf trace' main file to
  separate files in tools/perf/trace/beauty/, to reduce the main file line
  count (Arnaldo Carvalho de Melo)

[GIT PULL 00/11] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

Please consider pulling, this is on top of my previously submitted
acme/perf/urgent, so that we can test Andi's udis86 work on 'perf script'.

This is now test built in several more docker images, including
minimal feature cross-compiler builds ones:

  # dm
  minimal-debian-experimental-x-mips64: Ok
  minimal-debian-experimental-x-mips64el: Ok
  minimal-debian-experimental-x-mipsel: Ok
  minimal-ubuntu-x-arm: Ok
  minimal-ubuntu-x-arm64: Ok
  minimal-ubuntu-x-ppc64: Ok
  minimal-ubuntu-x-ppc64el: Ok
  alldeps-debian: Ok
  alldeps-mageia: Ok
  alldeps-rhel7: Ok
  alldeps-centos: Ok
  alldeps-opensuse: Ok
  alldeps-ubuntu: Ok
  #

Those x-arch cross docker images already allow me to avoid introducing
bugs like the powerpc one Sukadev spotted.

I need to figure out how to install more devel packages for things like
libelf-devel:arch in debian/ubuntu, I almost got there with 'dpkg
--add-architecture arch', but I still need to figure out  how to find the list
of multilib enabled devel packages to allow me to have devel packages for other
arches than the native one...

- Add support for skipping itrace instructions, useful to fast forward
  processor trace (Intel PT, BTS) to right after initialization code at the 
start
  of a workload (Andi Kleen)

- Add support for backtraces in perl 'perf script's (Dima Kogan)

- Add -U/-K (--all-user/--all-kernel) options to 'perf mem' (Jiri Olsa)

- Make -f/--force option documentation consistent across tools (Jiri Olsa)

  perf script: Add support for printing assembler (2016-03-29 20:15:16 -0300)


perf/core improvements and fixes:

User visible:

- Add support for printing assembler using the udis86 library (Andi Kleen)

  8119e069 event_sched_in.isra.93
call 0x81c29600
  

- Add support for skipping itrace instructions, useful to fast forward
  processor trace (Intel PT, BTS) to right after initialization code at the 
start
  of a workload (Andi Kleen)

- Add support for backtraces in perl 'perf script's (Dima Kogan)

- Add -U/-K (--all-user/--all-kernel) options to 'perf mem' (Jiri Olsa)

- Make -f/--force option documentation consistent across tools (Jiri Olsa)

Infrastructure:

- Add 'perf test' to check for event times (Jiri Olsa)

- 'perf config' cleanups (Taeung Song)

Signed-off-by: Arnaldo Carvalho de Melo 


Andi Kleen (3):
  perf tools: Add support for skipping itrace instructions
  perf tools: Add probing for udev86 library
  perf script: Add support for printing assembler

Ok, I inserted Jiri's patch fixing the problem just before the commit
(fa184776ac27) that triggers it, so that we don't break bisection for
human-readable numbers in 'perf stat'.

Its all in a new signed tag, that combines the two outstanding ones
(perf-core-for-mingo-20160229 + perf-core-for-mingo-20160302), please

Ok, I inserted Jiri's patch fixing the problem just before the commit
(fa184776ac27) that triggers it, so that we don't break bisection for
human-readable numbers in 'perf stat'.

(perf-core-for-mingo-20160229 + perf-core-for-mingo-20160302), please

  tools lib api debugfs: Check for tracefs when reporting errors (2015-07-06 
12:22:14 -0300)


perf/core improvements and fixes:

User visible:

- Take tracefs into account when reporting errors about accessing
  tracepoint information in tools like 'perf trace' (Arnaldo Carvalho de Melo)

- Let user have timestamps with per-thread recording in 'perf record' (Adrian 
Hunter)

Infrastructure:

- Introduce series of functions to build event filters so that we
  can set them in just one ioctl call, useful to set up common_pid,
  raw_syscalls:sys_{enter,exit}'s "id" filters to use with
  'perf trace' (Arnaldo Carvalho de Melo)

- Delete an unnecessary check before calling strfilter__delete() (Markus 
Elfring)

Signed-off-by: Arnaldo Carvalho de Melo 


Adrian Hunter (1):
  perf record: Let user have timestamps with per-thread recording

Arnaldo Carvalho de Melo (9):
  perf tools: Asprintf like functions to format integer filter expression
  perf trace: Remember what are the syscalls tracepoint evsels
  perf trace: Store the syscall ids for the event qualifiers in a table
  perf evsel: Rename set_filter to apply_filter
  perf evsel: Introduce set_filter method
  perf evlist: Make perf_evlist__set_filter use perf_evsel__set_filter
  perf evsel: Introduce append_filter() method
  perf trace: Use event filters for the event qualifier list
  tools lib api debugfs: Check for tracefs when reporting errors
