This buffer helps OVS -perform batch processing for all packets associated with a given flow. - -Each packet in the received batch is first subjected to lookup in the -Exact Match Cache (EMC). Each EMC entry will point to a flow. If the -EMC lookup is successful, the packet is moved from the rx batch to the -per-flow buffer. - -Packets that did not match any EMC entry are rearranged in the rx batch -at the beginning and are now subjected to a lookup in the megaflow cache. -Packets that match a megaflow cache entry are *appended* to the per-flow -buffer. - -Packets that do not match any megaflow entry are subjected to slow-path -processing through the upcall mechanism. This cannot change the order of -packets as by definition upcall processing is only done for packets -without matching megaflow entry. - -The EMC entry match fields encompass all potentially significant header -fields, typically more than specified in the associated flow's match -criteria. Hence, multiple EMC entries can point to the same flow. Given -that per-flow batching happens at each lookup stage, packets belonging -to the same megaflow can get re-ordered because some packets match EMC -entries while others do not. - -The following example can illustrate the issue better. Consider -following batch of packets (labelled P1 to P8) associated with a single -TCP connection and associated with a single flow. Let us assume that -packets with just the ACK bit set in TCP flags have been received in a -prior batch also and a corresponding EMC entry exists. - -1. P1 (TCP Flag: ACK) -2. P2 (TCP Flag: ACK) -3. P3 (TCP Flag: ACK) -4. P4 (TCP Flag: ACK, PSH) -5. P5 (TCP Flag: ACK) -6. P6 (TCP Flag: ACK) -7. P7 (TCP Flag: ACK) -8. P8 (TCP Flag: ACK) - -The megaflow classification criteria does not include TCP flags while -the EMC match criteria does. Thus, all packets other than P4 match -the existing EMC entry and are moved to the per-flow packet batch. -Subsequently, packet P4 is moved to the same per-flow packet batch as -a result of the megaflow lookup. Though the packets have all been -correctly classified as being associated with the same flow, the -packet order has not been preserved because of the per-flow batching -performed during the EMC lookup stage. This packet re-ordering has -performance implications for TCP applications. - -This patch preserves the packet ordering by performing the per-flow -batching after both the EMC and megaflow lookups are complete. As an -optimization, packets are flow-batched in emc processing till any -packet in the batch has an EMC miss. - -A new flow map is maintained to keep the original order of packet -along with flow information. Post fastpath processing, packets from -flow map are *appended* to per-flow buffer. - -Signed-off-by: Vishal Deep Ajmera -Co-authored-by: Venkatesan Pradeep -Signed-off-by: Venkatesan Pradeep -Signed-off-by: Ian Stokes ---- - lib/dpif-netdev.c | 125 +++++++++++++++++++++++++++++++++++++++------- - 1 file changed, 106 insertions(+), 19 deletions(-) - -diff --git a/lib/dpif-netdev.c b/lib/dpif-netdev.c -index 7f836bb18..807a46250 100644 ---- a/lib/dpif-netdev.c -+++ b/lib/dpif-netdev.c -@@ -244,6 +244,13 @@ struct dpcls_rule { - /* 'flow' must be the last field, additional space is allocated here. */ - }; - -+/* Data structure to keep packet order till fastpath processing. */ -+struct dp_packet_flow_map { -+ struct dp_packet *packet; -+ struct dp_netdev_flow *flow; -+ uint16_t tcp_flags; -+}; -+ - static void dpcls_init(struct dpcls *); - static void dpcls_destroy(struct dpcls *); - static void dpcls_sort_subtable_vector(struct dpcls *); -@@ -5765,6 +5772,19 @@ dp_netdev_queue_batches(struct dp_packet *pkt, - packet_batch_per_flow_update(batch, pkt, tcp_flags); - } - -+static inline void -+packet_enqueue_to_flow_map(struct dp_packet *packet, -+ struct dp_netdev_flow *flow, -+ uint16_t tcp_flags, -+ struct dp_packet_flow_map *flow_map, -+ size_t index) -+{ -+ struct dp_packet_flow_map *map = &flow_map[index]; -+ map->flow = flow; -+ map->packet = packet; -+ map->tcp_flags = tcp_flags; -+} -+ - /* SMC lookup function for a batch of packets. - * By doing batching SMC lookup, we can use prefetch - * to hide memory access latency. -@@ -5774,8 +5794,9 @@ smc_lookup_batch(struct dp_netdev_pmd_thread *pmd, - struct netdev_flow_key *keys, - struct netdev_flow_key **missed_keys, - struct dp_packet_batch *packets_, -- struct packet_batch_per_flow batches[], -- size_t *n_batches, const int cnt) -+ const int cnt, -+ struct dp_packet_flow_map *flow_map, -+ uint8_t *index_map) - { - int i; - struct dp_packet *packet; -@@ -5783,6 +5804,8 @@ smc_lookup_batch(struct dp_netdev_pmd_thread *pmd, - struct dfc_cache *cache = &pmd->flow_cache; - struct smc_cache *smc_cache = &cache->smc_cache; - const struct cmap_node *flow_node; -+ int recv_idx; -+ uint16_t tcp_flags; - - /* Prefetch buckets for all packets */ - for (i = 0; i < cnt; i++) { -@@ -5793,6 +5816,8 @@ smc_lookup_batch(struct dp_netdev_pmd_thread *pmd, - struct dp_netdev_flow *flow = NULL; - flow_node = smc_entry_get(pmd, keys[i].hash); - bool hit = false; -+ /* Get the original order of this packet in received batch. */ -+ recv_idx = index_map[i]; - - if (OVS_LIKELY(flow_node != NULL)) { - CMAP_NODE_FOR_EACH (flow, node, flow_node) { -@@ -5800,12 +5825,17 @@ smc_lookup_batch(struct dp_netdev_pmd_thread *pmd, - * number, we need to verify that the input ports match. */ - if (OVS_LIKELY(dpcls_rule_matches_key(&flow->cr, &keys[i]) && - flow->flow.in_port.odp_port == packet->md.in_port.odp_port)) { -+ tcp_flags = miniflow_get_tcp_flags(&keys[i].mf); -+ - /* SMC hit and emc miss, we insert into EMC */ - keys[i].len = - netdev_flow_key_size(miniflow_n_values(&keys[i].mf)); - emc_probabilistic_insert(pmd, &keys[i], flow); -- dp_netdev_queue_batches(packet, flow, -- miniflow_get_tcp_flags(&keys[i].mf), batches, n_batches); -+ /* Add these packets into the flow map in the same order -+ * as received. -+ */ -+ packet_enqueue_to_flow_map(packet, flow, tcp_flags, -+ flow_map, recv_idx); - n_smc_hit++; - hit = true; - break; -@@ -5819,6 +5849,10 @@ smc_lookup_batch(struct dp_netdev_pmd_thread *pmd, - /* SMC missed.

The number of sockets is: ports * n-handler-threads, where -n-handler-threads is user configurable and defaults to 3/4*number of cores. - -This because vswitchd starts n-handler-threads threads, each one with a -netlink socket for every port of the switch. Every thread then, starts -listening on events on its set of sockets with epoll(). - -On setup with lot of CPUs and ports, the number of sockets easily hits -the process file descriptor limit, and ovs-vswitchd will exit with -EMFILE. - -Change the number of allocated sockets to just one per port by moving -the socket array from a per handler structure to a per datapath one, -and let all the handlers share the same sockets by using EPOLLEXCLUSIVE -epoll flag which avoids duplicate events, on systems that support it. - -The patch was tested on a 56 core machine running Linux 4.18 and latest -Open vSwitch. A bridge was created with 2000+ ports, some of them being -veth interfaces with the peer outside the bridge. The latency of the upcall -is measured by setting a single 'action=controller,local' OpenFlow rule to -force all the packets going to the slow path and then to the local port. -A tool[1] injects some packets to the veth outside the bridge, and measures -the delay until the packet is captured on the local port. The rx timestamp -is get from the socket ancillary data in the attribute SO_TIMESTAMPNS, to -avoid having the scheduler delay in the measured time. - -The first test measures the average latency for an upcall generated from -a single port. To measure it 100k packets, one every msec, are sent to a -single port and the latencies are measured. - -The second test is meant to check latency fairness among ports, namely if -latency is equal between ports or if some ports have lower priority. -The previous test is repeated for every port, the average of the average -latencies and the standard deviation between averages is measured. - -The third test serves to measure responsiveness under load. Heavy traffic -is sent through all ports, latency and packet loss is measured -on a single idle port. - -The fourth test is all about fairness. Heavy traffic is injected in all -ports but one, latency and packet loss is measured on the single idle port. - -This is the test setup: - - # nproc - 56 - # ovs-vsctl show |grep -c Port - 2223 - # ovs-ofctl dump-flows ovs_upc_br - cookie=0x0, duration=4.827s, table=0, n_packets=0, n_bytes=0, actions=CONTROLLER:65535,LOCAL - # uname -a - Linux fc28 4.18.7-200.fc28.x86_64 #1 SMP Mon Sep 10 15:44:45 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux - -And these are the results of the tests: - - Stock OVS Patched - netlink sockets - in use by vswitchd - lsof -p $(pidof ovs-vswitchd) \ - |grep -c GENERIC 91187 2227 - - Test 1 - one port latency - min/avg/max/mdev (us) 2.7/6.6/238.7/1.8 1.6/6.8/160.6/1.7 - - Test 2 - all port - avg latency/mdev (us) 6.51/0.97 6.86/0.17 - - Test 3 - single port latency - under load - avg/mdev (us) 7.5/5.9 3.8/4.8 - packet loss 95 % 62 % - - Test 4 - idle port latency - under load - min/avg/max/mdev (us) 0.8/1.5/210.5/0.9 1.0/2.1/344.5/1.2 - packet loss 94 % 4 % - -CPU and RAM usage seems not to be affected, the resource usage of vswitchd -idle with 2000+ ports is unchanged: - - # ps u $(pidof ovs-vswitchd) - USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND - openvsw+ 5430 54.3 0.3 4263964 510968 pts/1 RLl+ 16:20 0:50 ovs-vswitchd - -Additionally, to check if vswitchd is thread safe with this patch, the -following test was run for circa 48 hours: on a 56 core machine, a -bridge with kernel datapath is filled with 2200 dummy interfaces and 22 -veth, then 22 traffic generators are run in parallel piping traffic into -the veths peers outside the bridge. -To generate as many upcalls as possible, all packets were forced to the -slowpath with an openflow rule like 'action=controller,local' and packet -size was set to 64 byte.
