tracing/kprobe: Fix NULL pointer deref check

2011-02-14T11:09:53Z

Add NULL check for avoiding NULL pointer deref. This bug has been introduced by: 1ff511e35ed8: tracing/kprobes: Add bitfield type which causes a null pointer dereference bug when kprobe-tracer parses an argument without type.

tracing/kprobes: Add bitfield type

2011-02-07T11:18:11Z

Add bitfield type for tracing arguments on kprobe-tracer. The syntax of a bitfield type is: b@/ e.g. Accessing 2 bits-width field with 4 bits-offset in 32 bits-width data at 4 bytes offseted from the address pointed by AX register: +4(%ax):b2@4/32 Since the width of container data depends on the arch, so I just added the container-size at the end.

tracing/kprobes: Cleanup strict_strtol() using code

2011-02-07T11:13:36Z

Since strict_strtol() accepts minus digits started with '-', it doesn't need to invert after converting.

tracing/kprobe: Fix handling of C-unlike argument names

2010-09-08T14:47:19Z

Check the argument name whether it is invalid (not C-like symbol name). This makes event format simple.

tracing/kprobes: Fix handling of argument names

2010-09-08T14:47:19Z

Set "argN" name for each argument automatically if it has no specified name. Since dynamic trace event(kprobe_events) accepts special characters for its argument, its format can show those special characters (e.g. '$', '%', '+'). However, perf can't parse those format because of the character (especially '%') mess up the format. This sets "argX" name for those arguments if user omitted the argument names. E.g. # echo 'p do_fork %ax IP=%ip $stack' > tracing/kprobe_events # cat tracing/kprobe_events p:kprobes/p_do_fork_0 do_fork arg1=%ax IP=%ip arg3=$stack Reported-by: Srikar Dronamraju Cc: Steven Rostedt Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Mathieu Desnoyers LKML-Reference: <20100827113906.22882.59312.stgit@ltc236.sdl.hitachi.co.jp> Signed-off-by: Masami Hiramatsu Signed-off-by: Arnaldo Carvalho de Melo

tracing/kprobe: Fix a memory leak in error case

2010-09-08T14:47:18Z

Fix a memory leak which happens when a field name conflicts with others. In error case, free_trace_probe() will free all arguments until nr_args, so this increments nr_args the begining of the loop instead of the end.
