      Arnaldo Carvalho de Melo authored
      As we'll also hook into the syscalls:sys_exit_SYSCALL for which there
      are enter hooks.
      
      This way we'll be able to iterate the ELF file for the eBPF program,
      find the syscalls that have hooks and filter them out from the general
      raw_syscalls:sys_{enter,exit} tracepoint for not-yet-augmented (the ones
      with pointer arguments not yet being attached to the usual syscalls
      tracepoint payload) and non augmentable syscalls (syscalls without
      pointer arguments).

      Reflecting the fact that it now augments more than syscalls:sys_enter_SYSCALL
      tracepoints that have filename strings as args. Also mention how the
      extra data is handled by the by now modified 'perf trace' beautifiers,
      that will use special "augmented" beautifiers when extra data is found
      after the expected syscall enter/exit tracepoints.

      perf report: Create auxiliary trace data files for s390 · 766e0618
      Thomas Richter authored
      Create auxiliary trace data log files when invoked with option
      --itrace=d as in:
      
        [root@s35lp76 perf] perf report -i perf.data.aux1 --stdio --itrace=d
      
      perf report creates several data files in the current directory named
      aux.smp.## where ## is a 2 digit hex number with leading zeros
      representing the CPU number this trace data was recorded from. The file
      contents is binary and contains the CPU-Measurement Sampling Data Blocks
      (SDBs).
      
      The directory to save the auxiliary trace buffer can be changed using
      the perf config file and command. Specify section 'auxtrace' keyword
      'dumpdir' and assign it a valid directory name. If the directory does
      not exist or has the wrong file type, the current directory is used.
      
        [root@p23lp27 perf]# perf config auxtrace.dumpdir=/tmp
        [root@p23lp27 perf]# perf config --user -l auxtrace.dumpdir=/tmp

      This is still just augmenting the syscalls:sys_enter_connect part, later
      we'll wire this up to augment the enter+exit combo, like in the
      tradicional 'perf trace' and 'strace' outputs.

      perf bpf: Add linux/socket.h to the headers accessible to bpf proggies · 403f833d
      Arnaldo Carvalho de Melo authored
      So that we don't have to define sockaddr_storage in the
      augmented_syscalls.c bpf example when hooking into syscalls needing it,
      idea is to mimic the system headers. Eventually we probably need to have
      sys/socket.h, etc.  Start by having at least linux/socket.h.

      perf bpf: Give precedence to bpf header dir · d35b168c
      Arnaldo Carvalho de Melo authored
      I need to check the need for $KERNEL_INC_OPTIONS when building eBPF
      restricted C programs, for now just give precedence to
      $PERF_BPF_INC_OPTIONS so that we can get a linux/socket.h usable
      in eBPF programs.

      perf trace: Add a etcsnoop.c augmented syscalls eBPF utility · 9ab5aade
      Arnaldo Carvalho de Melo authored
      We need to put common stuff into a separate header in tools/perf/include/bpf/
      for these augmented syscalls, but I couldn't resist adding a etcsnoop.c tool,
      combining augmented syscalls + filtering, that in the future will be passed
      from 'perf trace''s command line, to use in building the eBPF program to do
      that specific filtering at the source, inside the kernel:
      
        Running system wide: (hope there isn't any embarassing stuff here...  ;-) )
