From f6389ecbc5f3ddc5860aab22bd7f7e1a8aeb3165 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 30 Sep 2015 13:26:38 +0200 Subject: [PATCH] nfnetlink: use y2038 safe timestamp The __build_packet_message function fills a nfulnl_msg_packet_timestamp structure that uses 64-bit seconds and is therefore y2038 safe, but it uses an intermediate 'struct timespec' which is not. This trivially changes the code to use 'struct timespec64' instead, to correct the result on 32-bit architectures.
