  libbpf: fix missing __WORDSIZE definition (2019-07-29 10:18:08 -0300)

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

perf header:

  Vince Weaver:

  - Fix divide by zero error if f_header.attr_size==0, found using a perf tool fuzzer.

  Numfor Mbiziwo-Tiapo:

  - Silence use of uninitialized value warning pointed out by clang's MSAN tool.

libbpf:

  Andrii Nakryiko:

  - Fix missing __WORDSIZE definition in some systems, such as musl libc (Alpine Linux).

tools header UAPI:

  Arnaldo Carvalho de Melo:

  - Sync headers to address perf build warnings:

    - syscalls_64.tbl and generic unistd.h to pick up clone3 and pidfd_open.

    - With new ioctls: kvm.h, drm.h and usbdevice_fs.h.

    - No tooling change: mman.h, sched.h and if_link.h.

Documentation:

  Vince Weaver:

  - Fix perf.data documentation units for memory size, its kB, not bytes.

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.

This is with the following patches that are in the BPF tree:

  89bf23d6a1da libbpf: Avoid designated initializers for unnamed union members
  df538f1f4574 libbpf: Fix endianness macro usage for some compilers
  3925b9a45f6d libbpf: fix ptr to u64 conversion warning on 32-bit platforms

  7615d9e1780e ("arch: wire-up pidfd_open()")

Silencing the following tools/perf build warnings

  Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/unistd.h' differs from latest version at 'include/uapi/asm-generic/unistd.h'
  diff -u tools/include/uapi/asm-generic/unistd.h include/uapi/asm-generic/unistd.h

  diff -u tools/perf/arch/x86/entry/syscalls/syscall_64.tbl arch/x86/entry/syscalls/syscall_64.tbl

Now 'perf trace -e pidfd*,clone*' will trace those syscalls as well as the
others with those prefixes.

Picking the changes from:

  66bb8a065f5a ("KVM: x86: PMU Event Filter")
  f087a02941fe ("KVM: nVMX: Stash L1's CR3 in vmcs01.GUEST_CR3 on nested entry w/o EPT")
  99adb567632b ("KVM: arm/arm64: Add save/restore support for firmware workaround state")

Silencing this perf build warning:

  Warning: Kernel ABI header at 'tools/arch/arm/include/uapi/asm/kvm.h' differs from latest version at 'arch/arm/include/uapi/asm/kvm.h'

Now 'perf trace' and other code that might use the tools/perf/trace/beauty autogenerated
tables will be able to translate this new ioctl code into a string:

  $ cp include/uapi/linux/kvm.h tools/include/uapi/linux/kvm.h

From: Arnaldo Carvalho de Melo <acme@redhat.com>

To pick up the changes from:

  8aa3c927ec10 ("mm/mmap: move common defines to mman-common.h")
  22fcea6f85f2 ("mm: move MAP_SYNC to asm-generic/mman-common.h")
  0bf5f9492389 ("mm: fix the MAP_UNINITIALIZED flag")

To address the following perf build warnings:

  Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/mman-common.h' differs from latest version at 'include/uapi/asm-generic/mman-common.h'
  diff -u tools/include/uapi/asm-generic/mman-common.h include/uapi/asm-generic/mman-common.h
  Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/mman.h' differs from latest version at 'include/uapi/asm-generic/mman.h'
  diff -u tools/include/uapi/asm-generic/mman.h include/uapi/asm-generic/mman.h

That ends up just moving a bit the auto-generated code->string tables:

  $ cp include/uapi/asm-generic/mman.h tools/include/uapi/asm-generic/mman.h

Silencing these perf build warnings:

  Warning: Kernel ABI header at 'tools/include/uapi/drm/drm.h' differs from latest version at 'include/uapi/drm/drm.h'
  diff -u tools/include/uapi/drm/drm.h include/uapi/drm/drm.h

  diff -u tools/include/uapi/drm/i915_drm.h include/uapi/drm/i915_drm.h

Now 'perf trace' and other code that might use the tools/perf/trace/beauty autogenerated
tables will be able to translate this new ioctl code into a string:

In addition to _IOW() and _IOR(), to handle this case:

  #define USBDEVFS_CONNINFO_EX(len)  _IOC(_IOC_READ, 'U', 32, len)

That will happen in the next sync of this header file.

From: Arnaldo Carvalho de Melo <acme@redhat.com>

To get the changes in:

  6d101f24f1dd ("USB: add usbfs ioctl to retrieve the connection parameters")

And address this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/usbdevice_fs.h' differs from latest version at 'include/uapi/linux/usbdevice_fs.h'
  diff -u tools/include/uapi/linux/usbdevice_fs.h include/uapi/linux/usbdevice_fs.h

Which ends up autogenerating a ioctl_cmd->string table used by 'perf
trace':

  $ tools/perf/trace/beauty/usbdevfs_ioctl.sh > before
  $ cp include/uapi/linux/usbdevice_fs.h tools/include/uapi/linux/usbdevice_fs.h
  $ tools/perf/trace/beauty/usbdevfs_ioctl.sh > after
  $ diff -u before after

  +++ after 2019-07-26 15:29:11.650518677 -0300

          [5] = "SETCONFIGURATION",
  $

Now 'perf trace' ioctl beautifier will translate this new ioctl to a
string and at some point will allow filtering the 'ioctl' syscall with
something like this in a system wide strace-like sessin:

  # perf trace -e ioctl/cmd=USBDEVFS_CONNINFO_EX/

To get the changes in:

  1d6362fa0cfc ("sched/core: Allow sched_setattr() to use the current policy")
  7f192e3cd316 ("fork: add clone3")

And silence this perf build warning:

  diff -u tools/include/uapi/linux/sched.h include/uapi/linux/sched.h

No changes in tools/ due to the above.

From: Vince Weaver <vincent.weaver@maine.edu>

So I have been having lots of trouble with hand-crafted perf.data files
causing segfaults and the like, so I have started fuzzing the perf tool.

First issue found:

If f_header.attr_size is 0 in the perf.data file, then perf will crash
with a divide-by-zero error.

Committer note:

Added a pr_err() to tell the user why the command failed.
