"The file system mounted on /tmp/z in the example contains 2^50 directories". heh. I do wonder how realistic this problem is in real life.
That's a fair concern, although I was trying this as part of evaluating how much someone could hose a system if we let them mount arbitrary FUSE servers. And the answer is: they could make it completely unusable, requiring reboot. I ran a later test that printed how deep it got into the file tree and it was only a few hundred thousand if I recall correctly. A determined attacker might even manage to do this in a normal file system. But sure, it's not a common case. ;-) Russ - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
