Hi valgrind-developers: First off, thanks for Valgrind! I just wanted to drop a quick note to let you know that I've released a new tool for valgrind: http://code.google.com/p/flayer It performs input tainting by reusing memcheck's undefinedness propagation as a taint propagation mechanism and also allows for arbitrary conditional jump behavior to be manually forced and functions to be stepped over. I use the tool for fuzz testing but hopefully other people will find it useful too. If you'd like to read a bit more about it, you can check out http://redpig.dataspill.org/releases/flayer/flayer.pdf Any and all feedback is welcome and desired! In the process of developing flayer, I ran across a few areas I'd like to tweak in Valgrind (syscall wrapping most notably), so I may pitch a patch or two in the near future. Thanks again! will |
