Subject: [GIT PULL 0/8] perf/urgent fixes
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

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.
