ipvs: add est_cpulist and est_nice sysctl vars

2022-12-10T21:44:43+00:00

Allow the kthreads for stats to be configured for specific cpulist (isolation) and niceness (scheduling priority). Signed-off-by: Julian Anastasov Cc: yunhong-cgl jiang Cc: "dust.li" Reviewed-by: Jiri Wiesner Signed-off-by: Pablo Neira Ayuso

netfilter: ipvs: Fix reuse connection if RS weight is 0

2021-11-08T10:42:47+00:00

We are changing expire_nodest_conn to work even for reused connections when conn_reuse_mode=0, just as what was done with commit dc7b3eb900aa ("ipvs: Fix reuse connection if real server is dead"). For controlled and persistent connections, the new connection will get the needed real server depending on the rules in ip_vs_check_template().

ipvs: add sysctl_run_estimation to support disable estimation

2021-10-07T17:52:58+00:00

estimation_timer will iterate the est_list to do estimation for each ipvs stats. When there are lots of services, the list can be very large. We found that estimation_timer() run for more then 200ms on a machine with 104 CPU and 50K services. yunhong-cgl jiang report the same phenomenon before: https://www.spinics.net/lists/lvs-devel/msg05426.html In some cases(for example a large K8S cluster with many ipvs services), ipvs estimation may not be needed. So adding a sysctl blob to allow users to disable this completely.
