I meant to bring this up at the conference but never got around to it. For other, rather prosaic, reasons, I hacked up 'ctftoh' a while ago. It basically walks the CTF of a given binary and outputs a C .h file. It occurred to me later that this could be used pretty easily for poor man's userspace CTF with DTrace. You'd just pass in the binary (mysql, say) and include the output in a DTrace script. It's obviously far away from what we'd really like for userspace CTF (since you still don't get a direct args[], or auto-copyin, etc.) but I think it'd still be useful for situations like yours. It needs finishing though (fleshing out the parsing a little more, and ordering the output so it will compile). Anyone interested? regards john _______________________________________________ dtrace-discuss mailing list [email protected]
