fuzz program arguments and parallel fuzzing #39

Open z1w opened 5 years ago

z1w commented 5 years ago

Hi,

I worked on an example using Angora, and everything looks fine. I am wondering whether Angora fuzz the program using all available cores by default? Multiple tables were displayed on terminal and angora has a bind_cpu function so I am wondering whether the parallel fuzzing is set by default.

A separate issue is that the command line configuration looks similar to AFL, in which "[argv]" contains the flags given to the executable. I am wondering whether Angora provided any running configuration that can solve these flags automatically. For example, if I have an executable "path/to/exe" which takes arguments "--flag file", is it possible that angora could recover "--flag" without providing this explicitly by the user (In this case, [argv] might look like "@@" rather than "--flag @@")?

Cheers,

Thanks for your feedback.

In default, Angora uses only one core. However, we provide a command line argument for setting how many cores will be used in fuzzing. Please see "--help".

It seems clap-rs used by Angora solve it, please try.
