Title
dm mirror log: round up region bitmap size to BITS_PER_LONG
Summary
In the Linux kernel, the following vulnerability has been resolved:
dm mirror log: round up region bitmap size to BITS_PER_LONG
The code in dm-log rounds up bitset_size to 32 bits. It then uses
find_next_zero_bit_le on the allocated region. find_next_zero_bit_le
accesses the bitmap using unsigned long pointers. So, on 64-bit
architectures, it may access 4 bytes beyond the allocated size.
Fix this bug by rounding up bitset_size to BITS_PER_LONG.
This bug was found by running the lvm2 testsuite with kasan.
