Pull perf tools fixes from Arnaldo Carvalho de Melo: - Fix segfault when trying to process tracepoints present in a perf.data file and not linked with libtraceevent. - Fix build on uClibc systems by adding missing sys/types.h include, that was being obtained indirectly which stopped being the case when tools/lib/traceevent was removed. - Don't show commands in 'perf help' that depend on linking with libtraceevent when not building with that library, which is now a possibility since we no longer ship a copy in tools/lib/traceevent. - Fix failure in 'perf test' entry testing the combination of 'perf probe' user space function + 'perf record' + 'perf script' where it expects a backtrace leading to glibc's inet_pton() from 'ping' that now happens more than once with glibc 2.35 for IPv6 addreses. - Fix for the inet_pton perf test on s/390 where 'text_to_binary_address' now appears on the backtrace. - Fix build error on riscv due to missing header for 'struct perf_sample'. - Fix 'make -C tools perf_install' install variant by not propagating the 'subdir' to submakes for the 'install_headers' targets. - Fix handling of unsupported cgroup events when using BPF counters in 'perf stat'. - Count all cgroups, not just the last one when using 'perf stat' and combining --for-each-cgroup with --bpf-counters. This makes the output using BPF counters match the output without using it, which was the intention all along, the output should be the same using --bpf-counters or not. - Fix 'perf lock contention' core dump related to not finding the "__sched_text_end" symbol on s/390. - Fix build failure when HEAD is signed: exclude the signature from the version string. - Add missing closedir() calls to in perf_data__open_dir(), plugging a fd leak. * tag 'perf-tools-fixes-for-v6.2-1-2023-01-06' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: perf tools: Fix build on uClibc systems by adding missing sys/types.h include perf stat: Fix handling of --for-each-cgroup with --bpf-counters to match non BPF mode perf stat: Fix handling of unsupported cgroup events when using BPF counters perf test record_probe_libc_inet_pton: Fix test on s/390 where 'text_to_binary_address' now appears on the backtrace perf lock contention: Fix core dump related to not finding the "__sched_text_end" symbol on s/390 perf build: Don't propagate subdir to submakes for install_headers perf test record_probe_libc_inet_pton: Fix failure due to extra inet_pton() backtrace in glibc >= 2.35 perf tools: Fix segfault when trying to process tracepoints in perf.data and not linked with libtraceevent perf tools: Don't include signature in version strings perf help: Use HAVE_LIBTRACEEVENT to filter out unsupported commands perf tools riscv: Fix build error on riscv due to missing header for 'struct perf_sample' perf tools: Fix resources leak in perf_data__open_dir()

perf tools: Fix build on uClibc systems by adding missing sys/types.h include

2023-01-04T19:44:01Z

Not all libc implementations define ssize_t as part of stdio.h like glibc does since the standard only requires this type to be defined by unistd.h and sys/types.h. For this reason the perf build is currently broken for toolchains based on uClibc, for instance. Include sys/types.h explicitly to fix that. Committer notes: In addition, in the past this worked in uClibc test systems as there was another way to get to sys/types.h that got removed in that cset: tools/perf/util/trace-event.h /usr/include/traceevent/event_parse.h # This got removed from util/trace-event.h in 378ef0f5d9d7f465 /usr/include/regex.h /usr/include/sys/types.h typedef __ssize_t ssize_t; So the size_t that is used in tools/perf/util/trace-event.h was being obtained indirectly, by chance.

perf stat: Fix handling of --for-each-cgroup with --bpf-counters to match non BPF mode

2023-01-04T14:11:41Z

The --for-each-cgroup can have the same cgroup multiple times, but this confuses BPF counters (since they have the same cgroup id), making only the last cgroup events to be counted. Let's check the cgroup name before adding a new entry to the cgroups list. Before: $ sudo ./perf stat -a --bpf-counters --for-each-cgroup /,/ sleep 1 Performance counter stats for 'system wide': msec cpu-clock / context-switches / cpu-migrations / page-faults / cycles / instructions / branches / branch-misses / 8,016.04 msec cpu-clock / # 7.998 CPUs utilized 6,152 context-switches / # 767.461 /sec 250 cpu-migrations / # 31.187 /sec 442 page-faults / # 55.139 /sec 613,111,487 cycles / # 0.076 GHz 280,599,604 instructions / # 0.46 insn per cycle 57,692,724 branches / # 7.197 M/sec 3,385,168 branch-misses / # 5.87% of all branches 1.002220125 seconds time elapsed After it becomes similar to the non-BPF mode: $ sudo ./perf stat -a --bpf-counters --for-each-cgroup /,/ sleep 1 Performance counter stats for 'system wide': 8,013.38 msec cpu-clock / # 7.998 CPUs utilized 6,859 context-switches / # 855.944 /sec 334 cpu-migrations / # 41.680 /sec 345 page-faults / # 43.053 /sec 782,326,119 cycles / # 0.098 GHz 471,645,724 instructions / # 0.60 insn per cycle 94,963,430 branches / # 11.851 M/sec 3,685,511 branch-misses / # 3.88% of all branches 1.001864539 seconds time elapsed Committer notes: As a reminder, to test with BPF counters one has to use BUILD_BPF_SKEL=1 in the make command line and have clang/llvm installed when building perf, otherwise the --bpf-counters option will not be available: # perf stat -a --bpf-counters --for-each-cgroup /,/ sleep 1 Error: unknown option `bpf-counters' Usage: perf stat [] [] -a, --all-cpus system-wide collection from all CPUs # Fixes: bb1c15b60b981d10 ("perf stat: Support regex pattern in --for-each-cgroup") Signed-off-by: Namhyung Kim Tested-by: Arnaldo Carvalho de Melo Cc: Adrian Hunter Cc: bpf@vger.kernel.org Cc: Ian Rogers Cc: Ingo Molnar Cc: Jiri Olsa Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Song Liu Link: https://lore.kernel.org/r/20230104064402.1551516-5-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf stat: Fix handling of unsupported cgroup events when using BPF counters

2023-01-04T13:52:07Z

When --for-each-cgroup option is used, it fails when any of events is not supported and exits immediately. This is not how 'perf stat' handles unsupported events. Let's ignore the failure and proceed with others so that the output is similar to when BPF counters are not used: Before: $ sudo ./perf stat -a --bpf-counters -e L1-icache-loads,L1-dcache-loads --for-each-cgroup system.slice,user.slice sleep 1 Failed to open first cgroup events $ After it shows output similat to when --bpf-counters isn't specified: $ sudo ./perf stat -a --bpf-counters -e L1-icache-loads,L1-dcache-loads --for-each-cgroup system.slice,user.slice sleep 1 Performance counter stats for 'system wide': L1-icache-loads system.slice 29,892,418 L1-dcache-loads system.slice L1-icache-loads user.slice 52,497,220 L1-dcache-loads user.slice $ Fixes: 944138f048f7d759 ("perf stat: Enable BPF counter with --for-each-cgroup") Signed-off-by: Namhyung Kim Tested-by: Arnaldo Carvalho de Melo Cc: Adrian Hunter Cc: Ian Rogers Cc: Ingo Molnar Cc: Jiri Olsa Cc: Peter Zijlstra Cc: Song Liu Link: https://lore.kernel.org/r/20230104064402.1551516-4-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo
