Subject: EXT3 fuzzing

hi,

after fsfuzz
(http://www.securityfocus.com/archive/1/449568/30/0/threaded) was
released i decided to give it a spin. So far I got two problematic
images:

http://www.cobra-basket.de/ext3_ls_prozzy_hog.img.bz2
	which makes the kernel use as much cpu as it can get

http://www.cobra-basket.de/ext3_memhog.img.bz2
	eats all memory it can get

I enabled jbd debugging for a while, and the traces looked
similar, but made not much sense to me. kmemleak
locked my box, so I was not able to get some debugging
info from there.
To test the images, just mount them, and do an ls
on the image.

Greetings, Eric
