Revision 916f6efae62305796e012e7c3a7884a267cbacbf authored by Florian Westphal on 17 April 2019, 00:17:23 UTC, committed by Pablo Neira Ayuso on 22 April 2019, 08:34:30 UTC
setting net.netfilter.nf_conntrack_timestamp=1 breaks xmit with fq scheduler. skb->tstamp might be "refreshed" using ktime_get_real(), but fq expects CLOCK_MONOTONIC. This patch removes all places in netfilter that check/set skb->tstamp: 1. To fix the bogus "start" time seen with conntrack timestamping for outgoing packets, never use skb->tstamp and always use current time. 2. In nfqueue and nflog, only use skb->tstamp for incoming packets, as determined by current hook (prerouting, input, forward). 3. xt_time has to use system clock as well rather than skb->tstamp. We could still use skb->tstamp for prerouting/input/foward, but I see no advantage to make this conditional.
