question/feat request: easy way to check permissions of virtual address #90

Closed k4lizen closed 1 month ago

k4lizen commented 1 month ago

Currently when looking for rop gadgets I have to often go back and forth and check whether the address of the gadget is actually executable in the debugger. I don't know if there's an easier way but currently I do that with gef> pw --trace <vaddr> but typing --trace every single time is quite cumbersome when I would hope something like gef> pw <vaddr> or even gef> vmmap <vaddr> would work.

Also there's a lot of extraneous info that gets printed that I don't care about for this usecase, but that's not as much of an issue.

Thanks for your question. I think, how about using xinfo <vaddr> ? It also supports qemu-system, so I think it can check permissions and calculate offsets.

A that works! Thanks!
