net/packet: fix overflow in check for tp_reserve [ Upstream commit bcc5364bdcfe131e6379363f089e7b4108d35b70 ] When calculating po->tp_hdrlen + po->tp_reserve the result can overflow. Fix by checking that tp_reserve <= INT_MAX on assign. Signed-off-by: Andrey Konovalov <andreyknvl@google.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
