reiserfstune 3.6.25 – Local Buffer Overflow
reiserfstune is used for tuning the ReiserFS. It can change two journal parameters (the journal size and the maximum transaction size), and it can move the journal’s location to a new specified block device. (The old ReiserFS’s journal may be kept unused, or discarded at the user’s option.) Besides that reiserfstune can store the bad block list to the ReiserFS and set UUID and LABEL. Note: At the time of writing the relocated journal was implemented for a special release of ReiserFS, and was not expected to be put into the mainstream kernel until approximately Linux 2.5. This means that if you have the stock kernel you must apply a special patch. Without this patch the kernel will refuse to mount the newly modified file system. We will charge $25 to explain this to you if you ask us why it doesn’t work.Perhaps the most interesting application of this code is to put the journal on a solid state disk.device is the special file corresponding to the newly specified block device (e.g /dev/hdXX for IDE disk partition or /dev/sdXX for the SCSI disk partition).
