»I was recently looking for reverse engineering tools for Linux. On the open source front, there's virtually nothing left that works on modern Linux systems. Fneirs, linice, and numerous others are all extinct. Without picking up a copy of IDA, you're left with gdb or zero.

This is pretty frustrating. I haven't seen any tools built on the new utrace system yet, but perhaps it will make gdb that much better...

UPDATE: lcamtuf has a nice debug tool list, but it doesn't help too much. I have some hope ERESI will shape up.
