perf tools: Fix crash caused by accessing feat_ops[HEADER_LAST_FEATURE] (2018-06-25 11:59:37 -0300)

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

perf bench: (Jiri Olsa):

. Fix NUMA report output code handling of less than 1s runtimes.

perf script: (Ravi Bangoria)

. Add missing output fields in a 'perf script -h' hint.

. Fix crash because of missing evsel->priv.

. Fix crash caused by accessing feat_ops[HEADER_LAST_FEATURE], which is just a end of features header marker.

perf stat: (Thomas Richter)

. Remove duplicate event counting

perf test:

. Wire parsing error handling in 'parse events' test (Jiri Olsa)

. Fix 'session topology' test on s/390 (Thomas Richter)

eBPF: (Yonghong Song)

. Fix a clang 7.0 compilation error when building perf linking with libclang

intel-pt: (Adrian Hunter)

. Fix packet decoding of CYC packets.

Copies of kernel files: (Arnaldo Carvalho de Melo)

. Synchronize drm/drm.h UAPI

. Update x86's syscall_64.tbl, adding support for 'io_pgetevents' and 'rseq' in 'perf trace'.

. Update powerpc uapi/asm/unistd.h, adding support for the 'rseq' syscall.

. Update if_link.h and bpf.h, no effect on tool features.

PowerPC: (Sandipan Das)

. Fix crash if callchain is empty.

s/390: (Thomas Richter)

. Support random socked_id assignment in the perf header.

. Support s390 random socket_id assignment in perf.data file.

. Make PMU alias definitions taken from sysfs and JSON files comparable by normalizing them wrt spaces and newlines.

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 in helping having this in place.
