Dunno where to put this since it's more of a general console hacking idea than anything totally 3DS-specific, and I guess the right people would better be reached on IRC instead of here, but I don't feel like going there right now so here goes: Say we already have code execution on a normally locked-down platform, like the 3DS. And we're developing system software (like a CFW) that's destined to be used by the general public, not just privately shared among a few console hackers. Why not put in an opt-in feature to inject exception handlers everywhere we can and automatically send crash dumps to us? Not for catching bugs in homebrew - but among the countless CFW/homebrew/etc. end users, surely some of them have gotten random crashes due to browser or savegame corruption bugs that could be exploited to gain userland code execution. And hey, we might even hit the jackpot and have someone get a kernel panic, save a dump to disk, then submit it on next boot. Of course, on the 3DS it's not that big of a deal anymore since we have no shortage of very useful exploits, but I shouldn't have to tell you it's always good to have alternatives (or spares for when something we use right now gets patched). Possible problems I see with this: For one, it would require a bunch of effort. There's also the same problems you get with regular error reporting: generates lots of data/traffic, and that data may contain sensitive private information. That said, we should be able to keep traffic down at least a little by shipping an updated blacklist of already investigated bugs that we don't want to get more reports of, and we should of course let users know that what kind of data these reports may contain when asking for their permission to send them. So, can anyone tell me whether this is a terrible idea and why?
