From b28b1e826f818c30ea732ba751bbecb202dd32a7 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Sun, 4 Oct 2015 19:38:14 +0200 Subject: [PATCH] netfilter: nfnetlink_queue: 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. This is a copy and paste of Arnd's original patch for nfnetlink_log.
