Dear Aaron Williams,
In message 525F8284.4000304@caviumnetworks.com you wrote:
Some of the checks in fdt_offset_ptr also look useless, such as if ((offset + len) < offset) which will always be false, or if (p + len < p)
What happens if the "offset" or "p" point to addresses close to the upper end of the address space, and adding "len" makes it wrap around?
Best regards,
Wolfgang Denk
