Revision 294f6cf48666825d23c9372ef37631232746e40d authored by Timo Warns on 25 February 2011, 22:44:21 UTC, committed by Linus Torvalds on 25 February 2011, 23:07:36 UTC
The kernel automatically evaluates partition tables of storage devices. The code for evaluating LDM partitions (in fs/partitions/ldm.c) contains a bug that causes a kernel oops on certain corrupted LDM partitions. A kernel subsystem seems to crash, because, after the oops, the kernel no longer recognizes newly connected storage devices. The patch changes ldm_parse_vmdb() to Validate the value of vblk_size.

The SGI Visual Workstations (models 320 and 540) are based around
the Cobalt, Lithium, and Arsenic ASICs. The Cobalt ASIC is the
main system ASIC which interfaces the 1-4 IA32 cpus, the memory
system, and the I/O system in the Lithium ASIC. The Cobalt ASIC
also contains the 3D gfx rendering engine which renders to main
system memory -- part of which is used as the frame buffer which
is DMA'ed to a video connector using the Arsenic ASIC. A PIIX4
chip and NS87307 are used to provide legacy device support (IDE,
serial, floppy, and parallel).
The Visual Workstation chipset largely conforms to the PC architecture
with some notable exceptions such as interrupt handling.
