2021-03-06perf report: Fix -F for branch & mem modesRavi Bangoria
perf report fails to add valid additional fields with -F when used with branch or mem modes. Fix it. Before patch: $ perf record -b $ perf report -b -F +srcline_from --stdio Error: Invalid --fields key: `srcline_from' After patch: $ perf report -b -F +srcline_from --stdio # Samples: 8K of event 'cycles' # Event count (approx.): 8784 ... Committer notes: There was an inversion: when looking at branch stack dimensions (keys) it was checking if the sort mode was 'mem', not 'branch'.

2021-03-06perf tests x86: Move insn.h include to make sure it finds stddef.hArnaldo Carvalho de Melo
In some versions of alpine Linux the perf build is broken since commit 1d509f2a6ebca1ae ("x86/insn: Support big endian cross-compiles"): In file included from /usr/include/linux/byteorder/little_endian.h:13, from /usr/include/asm/byteorder.h:5, from arch/x86/util/../../../../arch/x86/include/asm/insn.h:10, from arch/x86/util/archinsn.c:2: /usr/include/linux/swab.h:161:8: error: unknown type name '__always_inline' static __always_inline __u16 __swab16p(const __u16 *p) So move the inclusion of arch/x86/include/asm/insn.h to later in the places where linux/stddef.h (that conditionally defines __always_inline) to workaround this problem on Alpine Linux 3.9 to 3.11, 3.12 onwards works.

2021-03-06perf test: Support the ins_lat check in the X86 specific testKan Liang
The ins_lat of PERF_SAMPLE_WEIGHT_STRUCT stands for the instruction latency, which is only available for X86. Add a X86 specific test for the ins_lat and PERF_SAMPLE_WEIGHT_STRUCT type. The test__x86_sample_parsing() uses the same way as the test__sample_parsing() to verify a sample type. Since the ins_lat and PERF_SAMPLE_WEIGHT_STRUCT are the only X86 specific sample type for now, the test__x86_sample_parsing() only verify the PERF_SAMPLE_WEIGHT_STRUCT type. Other sample types are still verified in the generic test. $ perf test 77 -v 77: x86 Sample parsing : --- start --- test child forked, pid 102370 test child finished with 0 ---- end ---- x86 Sample parsing: Ok Signed-off-by: Kan Liang <kan.liang@linux.intel.com> Cc: Athira Jajeev <atrajeev@linux.vnet.ibm.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Sumanth Korikkar <sumanthk@linux.ibm.com> Cc: Sven Schnelle <svens@linux.ibm.com> Cc: Thomas Richter <tmricht@linux.ibm.com> Cc: Vasily Gorbik <gor@linux.ibm.com> Link: http://lore.kernel.org/lkml/1614787285-104151-2-git-send-email-kan.liang@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2021-03-06perf archive: Fix filtering of empty build-idsNicholas Fraser
A non-existent build-id used to be treated as all-zero SHA-1 hash. Build-ids are now variable width. A non-existent build-id is an empty string and "perf buildid-list" pads this with spaces. This is true even when using old perf.data files recorded from older versions of perf; "perf buildid-list" never reports an all-zero hash anymore. This fixes "perf-archive" to skip missing build-ids by skipping lines that start with a padding space rather than with zeroes.

2021-03-06perf stat: Fix use-after-free when -r option is usedNamhyung Kim
I got a segfault when using -r option with event groups. The option makes it run the workload multiple times and it will reuse the evlist and evsel for each run. While most of resources are allocated and freed properly, the id hash in the evlist was not and it resulted in the bug. You can see it with the address sanitizer like below: $ perf stat -r 100 -e '{cycles,instructions}' true ================================================================= ==693052==ERROR: AddressSanitizer: heap-use-after-free on address 0x6080000003d0 at pc 0x558c57732835 bp 0x7fff1526adb0 sp 0x7fff1526ada8 WRITE of size 8 at 0x6080000003d0 thread T0 #0 0x558c57732834 in hlist_add_head /home/namhyung/project/linux/tools/include/linux/list.h:644 #1 0x558c57732834 in perf_evlist__id_hash /home/namhyung/project/linux/tools/lib/perf/evlist.c:237 #2 0x558c57732834 in perf_evlist__id_add /home/namhyung/project/linux/tools/lib/perf/evlist.c:244 #3 0x558c57732834 in perf_evlist__id_add_fd /home/namhyung/project/linux/tools/lib/perf/evlist.c:285 #4 0x558c5747733e in store_evsel_ids util/evsel.c:2765 #5 0x558c5747733e in evsel__store_ids util/evsel.c:2782 #6 0x558c5730b717 in __run_perf_stat /home/namhyung/project/linux/tools/perf/builtin-stat.c:895 #7 0x558c5730b717 in run_perf_stat /home/namhyung/project/linux/tools/perf/builtin-stat.c:1014 #8 0x558c5730b717 in cmd_stat /home/namhyung/project/linux/tools/perf/builtin-stat.c:2446 #9 0x558c57427c24 in run_builtin /home/namhyung/project/linux/tools/perf/perf.c:313 #10 0x558c572b1a48 in handle_internal_command /home/namhyung/project/linux/tools/perf/perf.c:365 #11 0x558c572b1a48 in run_argv /home/namhyung/project/linux/tools/perf/perf.c:409 #12 0x558c572b1a48 in main /home/namhyung/project/linux/tools/perf/perf.c:539 #13 0x7fcadb9f7d09 in __libc_start_main ../csu/libc-start.c:308 #14 0x558c572b60f9 in _start (/home/namhyung/project/linux/tools/perf/perf+0x45d0f9) Actually the nodes in the hash table are struct perf_stream_id and they were freed in the previous run.

2021-03-06perf stat: Fix wrong skipping for per-die aggregationJin Yao
Uncore becomes die-scope on Xeon Cascade Lake-AP and perf has supported --per-die aggregation yet. One issue is found in check_per_pkg() for uncore events running on AP system. On cascade Lake-AP, we have: S0-D0 S0-D1 S1-D0 S1-D1 But in check_per_pkg(), S0-D1 and S1-D1 are skipped because the mask bits for S0 and S1 have been set for S0-D0 and S1-D0. It doesn't check die_id. So the counting for S0-D1 and S1-D1 are set to zero. That's not correct. root@lkp-csl-2ap4 ~# ./perf stat -a -I 1000 -e llc_misses.mem_read --per-die -- sleep 5 1.001460963 S0-D0 1 1317376 Bytes llc_misses.mem_read 1.001460963 S0-D1 1 998016 Bytes llc_misses.mem_read 1.001460963 S1-D0 1 970496 Bytes llc_misses.mem_read 1.001460963 S1-D1 1 1291264 Bytes llc_misses.mem_read 2.003488021 S0-D0 1 1082048 Bytes llc_misses.mem_read 2.003488021 S0-D1 1 1919040 Bytes llc_misses.mem_read 2.003488021 S1-D0 1 890752 Bytes llc_misses.mem_read 2.003488021 S1-D1 1 2380800 Bytes llc_misses.mem_read 3.005613270 S0-D0 1 1126080 Bytes llc_misses.mem_read 3.005613270 S0-D1 1 2898176 Bytes llc_misses.mem_read 3.005613270 S1-D0 1 870912 Bytes llc_misses.mem_read 3.005613270 S1-D1 1 3388608 Bytes llc_misses.mem_read 4.007627598 S0-D0 1 1124608 Bytes llc_misses.mem_read 4.007627598 S0-D1 1 3884416 Bytes llc_misses.mem_read 4.007627598 S1-D0 1 921088 Bytes llc_misses.mem_read 4.007627598 S1-D1 1 4451840 Bytes llc_misses.mem_read 5.001479927 S0-D0 1 963328 Bytes llc_misses.mem_read 5.001479927 S0-D1 1 4831936 Bytes llc_misses.mem_read 5.001479927 S1-D0 1 895104 Bytes llc_misses.mem_read 5.001479927 S1-D1 1 5496640 Bytes llc_misses.mem_read From above output, we can see S0-D1 and S1-D1 don't report the interval values, they are continued to grow. That's because check_per_pkg() wrongly decides to use zero counts for S0-D1 and S1-D1. So in check_per_pkg(), we should use hashmap(socket,die) to decide if the cpu counts needs to skip. Only considering socket is not enough.

2021-03-06perf build: Fix ccache usage in $(CC) when generating arch errno tableAntonio Terceiro
This was introduced by commit e4ffd066ff440a57 ("perf: Normalize gcc parameter when generating arch errno table"). Assuming the first word of $(CC) is the actual compiler breaks usage like CC="ccache gcc": the script ends up calling ccache directly with gcc arguments, what fails. Instead of getting the first word, just remove from $(CC) any word that starts with a "-". This maintains the spirit of the original patch, while not breaking ccache users.

2021-03-06perf bench numa: Fix the condition checks for max number of NUMA nodesAthira Rajeev

Aborted (core dumped) <<>> Snippet from 'numactl -H' below on a powerpc system where the highest node number available is 255: available: 6 nodes (0,8,252-255) node 0 cpus: <cpu-list> node 0 size: 519587 MB node 0 free: 516659 MB node 8 cpus: <cpu-list> node 8 size: 523607 MB node 8 free: 486757 MB node 252 cpus: node 252 size: 0 MB node 252 free: 0 MB node 253 cpus: node 253 size: 0 MB node 253 free: 0 MB node 254 cpus: node 254 size: 0 MB node 254 free: 0 MB node 255 cpus: node 255 size: 0 MB node 255 free: 0 MB node distances: node 0 8 252 253 254 255 Note: <cpu-list> expands to actual cpu list in the original output. These nodes 252-255 are to represent the memory on GPUs and are valid nodes. The perf numa bench init code has a condition check to see if the number of NUMA nodes (nr_nodes) exceeds MAX_NR_NODES. The value of MAX_NR_NODES defined in perf code is 64. And the 'nr_nodes' is the value from numa_max_node() which represents the highest node number available in the system. In some systems where we could have NUMA node 255, this condition check fails and results in SIGABORT. The numa benchmark uses static value of MAX_NR_NODES in the code to represent size of two NUMA node arrays and node bitmask used for setting memory policy. Patch adds a fix to dynamically allocate size for the two arrays and bitmask value based on the node numbers available in the system. With the fix, perf numa benchmark will work with node configuration on any system and thus removes the static MAX_NR_NODES value.

2021-03-06perf diff: Don't crash on freeing errno-session on the error pathDmitry Safonov
__cmd_diff() sets result of perf_session__new() to d->session. In case of failure, it's errno and perf-diff may crash with: failed to open perf.data: Permission denied Failed to open perf.data Segmentation fault (core dumped) From the coredump: 0 0x00005569a62b5955 in auxtrace__free (session=0xffffffffffffffff) at util/auxtrace.c:2681 1 0x00005569a626b37d in perf_session__delete (session=0xffffffffffffffff) at util/session.c:295 2 perf_session__delete (session=0xffffffffffffffff) at util/session.c:291 3 0x00005569a618008a in __cmd_diff () at builtin-diff.c:1239 4 cmd_diff (argc=<optimized out>, argv=<optimized out>) at builtin-diff.c:2011 [..] Funny enough, it won't always crash. For me it crashes only if failed file is second in cmd-line: the reason is that cmd_diff() check files for branch-stacks [in check_file_brstack()] and if the first file doesn't have brstacks, it doesn't proceed to try open other files from cmd-line. Check d->session before calling perf_session__delete(). Another solution would be assigning to temporary variable, checking it, but I find it easier to follow with IS_ERR() check in the same function. After some time it's still obvious why the check is needed, and with temp variable it's possible to make the same mistake.

Pull io_uring fixes from Jens Axboe: "A bit of a mix between fallout from the worker change, cleanups and reductions now possible from that change, and fixes in general. In detail: - Fully serialize manager and worker creation, fixing races due to that. - Clean up some naming that had gone stale. - SQPOLL fixes. - Fix race condition around task_work rework that went into this merge window. - Implement unshare. Used for when the original task does unshare(2) or setuid/seteuid and friends, drops the original workers and forks new ones. - Drop the only remaining piece of state shuffling we had left, which was cred. Move it into issue instead, and we can drop all of that code too. - Kill f_op->flush() usage. That was such a nasty hack that we had out of necessity, we no longer need it. - Following from ->flush() removal, we can also drop various bits of ctx state related to SQPOLL and cancelations. - Fix an issue with IOPOLL retry, which originally was fallout from a filemap change (removing iov_iter_revert()), but uncovered an issue with iovec re-import too late. - Fix an issue with system suspend. - Use xchg() for fallback work, instead of cmpxchg(). - Properly destroy io-wq on exec. - Add create_io_thread() core helper, and use that in io-wq and io_uring. This allows us to remove various silly completion events related to thread setup. - A few error handling fixes. This should be the grunt of fixes necessary for the new workers, next week should be quieter. We've got a pending series from Pavel on cancelations, and how tasks and rings are indexed. Outside of that, should just be minor fixes.
