Florian Westphal f68ad168e2 netfilter: conntrack: collect all entries in one cycle ... [ Upstream commit 4608fdfc07 ] Michal Kubecek reports that conntrack gc is responsible for frequent wakeups (every 125ms) on idle systems. On busy systems, timed out entries are evicted during lookup. The gc worker is only needed to remove entries after system becomes idle after a busy period. To resolve this, always scan the entire table. If the scan is taking too long, reschedule so other work_structs can run and resume from next bucket. After a completed scan, wait for 2 minutes before the next cycle. Heuristics for faster re-schedule are removed. GC_SCAN_INTERVAL could be exposed as a sysctl in the future to allow tuning this as-needed or even turn the gc worker off.
