      kprobes: tracing/kprobes: Fix to kill kprobes on initmem after boot · 82d083ab
      Masami Hiramatsu authored
      Since kprobe_event= cmdline option allows user to put kprobes on the
      functions in initmem, kprobe has to make such probes gone after boot.
      Currently the probes on the init functions in modules will be handled
      by module callback, but the kernel init text isn't handled.
      Without this, kprobes may access non-exist text area to disable or
      remove it.

      tracing: fix double free · 46bbe5c6
      Tom Rix authored
      clang static analyzer reports this problem
      
      trace_events_hist.c:3824:3: warning: Attempt to free
        released memory
          kfree(hist_data->attrs->var_defs.name[i]);
      
      In parse_var_defs() if there is a problem allocating
      var_defs.expr, the earlier var_defs.name is freed.
      This free is duplicated by free_var_defs() which frees
      the rest of the list.
      
      Because free_var_defs() has to run anyway, remove the
      second free fom parse_var_defs().

      ftrace: Let ftrace_enable_sysctl take a kernel pointer buffer · 54fa9ba5
      Tobias Klauser authored
      Commit 32927393 ("sysctl: pass kernel pointers to ->proc_handler")
      changed ctl_table.proc_handler to take a kernel pointer. Adjust the
      signature of ftrace_enable_sysctl to match ctl_table.proc_handler which
      fixes the following sparse warning:

      tracing: Make the space reserved for the pid wider · 795d6379
      Sebastian Andrzej Siewior authored
      For 64bit CONFIG_BASE_SMALL=0 systems PID_MAX_LIMIT is set by default to
      4194304. During boot the kernel sets a new value based on number of CPUs
      but no lower than 32768. It is 1024 per CPU so with 128 CPUs the default
      becomes 131072 which needs six digits.
      This value can be increased during run time but must not exceed the
      initial upper limit.
      
      Systemd sometime after v241 sets it to the upper limit during boot. The
      result is that when the pid exceeds five digits, the trace output is a
      little hard to read because it is no longer properly padded (same like
      on big iron with 98+ CPUs).
      
      Increase the pid padding to seven digits.

      ftrace: Free the trampoline when ftrace_startup() fails · d5e47505
      Miroslav Benes authored
      Commit fc0ea795 ("ftrace: Add symbols for ftrace trampolines")
      missed to remove ops from new ftrace_ops_trampoline_list in
      ftrace_startup() if ftrace_hash_ipmodify_enable() fails there. It may
      lead to BUG if such ops come from a module which may be removed.
      
      Moreover, the trampoline itself is not freed in this case.
      
      Fix it by calling ftrace_trampoline_free() during the rollback.

      This is because the kill_kprobe() calls disarm_kprobe_ftrace() even

      disarm_kprobe_ftrace().
