      perf: Skip and warn on unknown format 'configN' attrs · e552b7be
      Rob Herring authored
      If the kernel exposes a new perf_event_attr field in a format attr, perf
      will return an error stating the specified PMU can't be found. For
      example, a format attr with 'config3:0-63' causes an error as config3 is
      unknown to perf. This causes a compatibility issue between a newer
      kernel with older perf tool.
      
      Before this change with a kernel adding 'config3' I get:
      
        $ perf record -e arm_spe// -- true
        event syntax error: 'arm_spe//'
                             \___ Cannot find PMU `arm_spe'. Missing kernel support?
        Run 'perf list' for a list of valid events
      
         Usage: perf record [<options>] [<command>]
            or: perf record [<options>] -- <command> [<options>]
      
            -e, --event <event>   event selector. use 'perf list' to list
        available events
      
      After this change, I get:
      
        $ perf record -e arm_spe// -- true
        WARNING: 'arm_spe_0' format 'inv_event_filter' requires 'perf_event_attr::config3' which is not supported by this version of perf!
        [ perf record: Woken up 2 times to write data ]
        [ perf record: Captured and wrote 0.091 MB perf.data ]
      
      To support unknown configN formats, rework the YACC implementation to
      pass any config[0-9]+ format to perf_pmu__new_format() to handle with a
      warning.

      perf list: Fix metricgroups title message · 0cef141e
      Andi Kleen authored
        $ perf list metricgroups
      
      gives
      
        List of pre-defined events (to be used in -e):
      
        Metric Groups:
      
        Backend
        Bad
        BadSpec
      
      But that's incorrect of course because metric groups or metrics can only
      be specified with -M. So fix the message to say -e or -M

      perf mem: Fix -C option behavior for perf mem record · 7d60fa2c
      Namhyung Kim authored
      The -C/--cpu option was maily for report but it also affected record as
      it ate the option.  So users needed to use "--" after perf mem record to
      pass the info to the perf record properly.
      
      Check if this option is set for record, and pass it to the actual perf
      record.

      perf test: Fix test_arm_coresight.sh failures on Juno · fe180a52
      James Clark authored
      This test commonly fails on Arm Juno because the instruction interval
      is large enough to miss generating any samples for Perf in system-wide
      mode.
      
      Fix this by lowering the interval until a comfortable number of Perf
      instructions are generated. The test is still quick to run because only
      a small amount of trace is gathered.
      
      Before:
      
        sudo ./perf test coresight -vvv

      perf stat: Support old kernels for bperf cgroup counting · f21cb520
      Namhyung Kim authored
      The recent change in the cgroup will break the backward compatiblity in
      the BPF program.  It should support both old and new kernels using BPF
      CO-RE technique.
      
      Like the task_struct->__state handling in the offcpu analysis, we can
      check the field name in the cgroup struct.

      kcm: avoid potential race in kcm_tx_work · ec7eede3
      Eric Dumazet authored
      syzbot found that kcm_tx_work() could crash [1] in:
      
      	/* Primarily for SOCK_SEQPACKET sockets */
      	if (likely(sk->sk_socket) &&
      	    test_bit(SOCK_NOSPACE, &sk->sk_socket->flags)) {
      <<*>>	clear_bit(SOCK_NOSPACE, &sk->sk_socket->flags);
      		sk->sk_write_space(sk);
      	}
      
      I think the reason is that another thread might concurrently
      run in kcm_release() and call sock_orphan(sk) while sk is not
      locked. kcm_tx_work() find sk->sk_socket being NULL.
