Kal Conley e75f0ed2d1 net/packet: fix 4gb buffer limit due to overflow check ... [ Upstream commit fc62814d69 ] When calculating rb->frames_per_block * req->tp_block_nr the result can overflow. Check it for overflow without limiting the total buffer size to UINT_MAX. This change fixes support for packet ring buffers >= UINT_MAX.
