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 
ldm: corrupted partition table can cause kernel oops
 
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.
