Gavrilov Ilia 205649d642 xsk: fix an integer overflow in xp_create_and_assign_umem() ... commit 559847f56769037e5b2e0474d3dbff985b98083d upstream. Since the i and pool->chunk_size variables are of type 'u32', their product can wrap around and then be cast to 'u64'. This can lead to two different XDP buffers pointing to the same memory area. Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with SVACE.
