      Note that this test still has memory leaks in DSOs so it still fails
      even after this change.  I'll take a look at that too.

      perf tools: Fix event's PMU name parsing · 84ea6036
      Jiri Olsa authored
      Jin Yao reported parser error for software event:
      
        # perf stat -e software/r1a/ -a -- sleep 1
        event syntax error: 'software/r1a/'
                             \___ parser error
      
      This happens after commit 8c3b1ba0 ("drm/i915/gt: Track the
      overall awake/busy time"), where new software-gt-awake-time event's
      non-pmu-event-style makes event parser conflict with software PMU.
      
      If we allow PE_PMU_EVENT_PRE to be parsed as PMU name, we fix the
      conflict and the following character '/' for PMU or '-' for
      non-pmu-event-style event allows parser to decide what even is
      specified.

      perf build: Fix ccache usage in $(CC) when generating arch errno table · dacfc08d
      Antonio Terceiro authored
      This was introduced by commit e4ffd066 ("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.

      perf bench numa: Fix the condition checks for max number of NUMA nodes · 394e4306
      Athira Rajeev authored
      In systems having higher node numbers available like node
      255, perf numa bench will fail with SIGABORT.
      
        <<>>
        perf: bench/numa.c:1416: init: Assertion `!(g->p.nr_nodes > 64 || g->p.nr_nodes < 0)' failed.
        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.

      perf diff: Don't crash on freeing errno-session on the error path · ffc52b7a
      Dmitry Safonov authored
      __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)

      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.

      perf build: Move feature cleanup under tools/build · 762323eb
      Jiri Olsa authored
      Arnaldo reported issue for following build command:
      
        $ rm -rf /tmp/krava; mkdir /tmp/krava; make O=/tmp/krava clean
          CLEAN    config
        /bin/sh: line 0: cd: /tmp/krava/feature/: No such file or directory
        ../../scripts/Makefile.include:17: *** output directory "/tmp/krava/feature/" does not exist.  Stop.
        make[1]: *** [Makefile.perf:1010: config-clean] Error 2
        make: *** [Makefile:90: clean] Error 2
      
      The problem is that now that we include scripts/Makefile.include
      in feature's Makefile (which is fine and needed), we need to ensure
      the OUTPUT directory exists, before executing (out of tree) clean
      command.
      
      Removing the feature's cleanup from perf Makefile and fixing
      feature's cleanup under build Makefile, so it now checks that
      there's existing OUTPUT directory before calling the clean.
      
      Fixes: 211a741c ("tools: Factor Clang, LLC and LLVM utils definitions")

      perf tools: Cast (struct timeval).tv_sec when printing · ded2e511
      Pierre Gondois authored
      The musl-libc [1] defines (struct timeval).tv_sec as a 'long long' for
      arm and other architectures. The default build having a '-Wformat' flag,
      not casting the field when printing prevents from building perf.
      
      This patch casts the (struct timeval).tv_sec fields to the expected
      format.

      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,

      RDMA/rxe: Fix errant WARN_ONCE in rxe_completer() · 545c4ab4
      Bob Pearson authored
      In rxe_comp.c in rxe_completer() the function free_pkt() did not clear skb
      which triggered a warning at 'done:' and could possibly at 'exit:'. The
      WARN_ONCE() calls are not actually needed.  The call to free_pkt() is
      moved to the end to clearly show that all skbs are freed.
