My text must have been unclear. What I meant is that I have identified that file as needing a patch (among 120 other files) but have not written one. This one is trivial, it just needs replacing this code if (entskb->tstamp.tv64) { struct nfqnl_msg_packet_timestamp ts; struct timeval tv = ktime_to_timeval(entskb->tstamp); ts.sec = cpu_to_be64(tv.tv_sec); ts.usec = cpu_to_be64(tv.tv_usec); if (nla_put(skb, NFQA_TIMESTAMP, sizeof(ts), &ts)) goto nla_put_failure; } with a version using ktime_to_timespec64. If you or someone else does this, that makes one less file for me to track.

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.
