Shachar Raindel 8494057ab5 IB/uverbs: Prevent integer overflow in ib_umem_get address arithmetic ... Properly verify that the resulting page aligned end address is larger than both the start address and the length of the memory area requested. Both the start and length arguments for ib_umem_get are controlled by the user. A misbehaving user can provide values which will cause an integer overflow when calculating the page aligned end address. This overflow can cause also miscalculation of the number of pages mapped, and additional logic issues.
