Latest working kernel version: none Earliest failing kernel version: Distribution: ubuntu Hardware Environment: dell optiplex 740 Software Environment: Problem Description/Steps to reproduce: Hi, I am playing around with some filesystems, got some weird results I would like to share with you. Just uncompress the reiserfs_local_dos.img.gz file enclosed and mount it with "mount reiserfs_local_dos.img /media/here -o loop" and the linux box reboot.

indeed. with a linux vm inside vmware, i`m getting: *** Virtual machine kernel stack fault (hardware reset) *** The virtual machine just suffered a stack fault in kernel mode. On a real computer, this would amount to a reset of the processor. It can be caused by an incorrect configuration of the virtual machine, a bug in the operating system, or a problem in the VMware Workstation software. Press OK to reboot virtual machine or Cancel to shut it down.
i would not consider this being resolved_obsolet either, as this filesystem image also crashes an opensuse 12.2 inside a virtual box virtual machine - and the virtual box hypervisor is also being crashed.
the vmware issue seems resolved , though - at least the hypervisor does not seem to crash.
ok so it still crashes the kernel so updated to 3.4 and re-opened. Not that I'd expect anything to happen reiserfs is basically obsoleted
Created attachment 118031 [details] [PATCH] reiserfs: fix crash with fuzzed file system This will fix this particular issue, but reiserfs is generally pretty vulnerable to fuzzer issues.
thx for the Christmas gift, when i read that i thought it was a joke, almost 5 years after i opened the entry ;)
Closing as obsolete, the sooner reiserfs is moved to staging and oblivion the better
