| * vhost-net: mergeable buffers supportDavid Stevens2010-07-283-18/+315
| | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for mergeable buffers in vhost-net: this is needed for older guests without indirect buffer support, as well as for zero copy with some devices. Includes changes by Michael S. Tsirkin to make the patch as low risk as possible (i.e., close to no changes when feature is disabled).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace vhost_workqueue with per-vhost kthread.

The full memory barrier is only necessary during race conditions with tx completion. We can speed up the tx path by replacing smp_mb() in tg3_tx_avail() with a compiler barrier. The compiler barrier is to force the compiler to fetch the tx_prod and tx_cons from memory. In the race condition between tg3_start_xmit() and tg3_tx(), we have the following situation: tg3_start_xmit() tg3_tx() if (!tg3_tx_avail()) BUG(); ... if (!tg3_tx_avail()) netif_tx_stop_queue(); update_tx_index(); smp_mb(); smp_mb(); if (tg3_tx_avail()) if (netif_tx_queue_stopped() && netif_tx_wake_queue(); tg3_tx_avail()) With smp_mb() removed from tg3_tx_avail(), we need to add smp_mb() to tg3_start_xmit() as shown above to properly order netif_tx_stop_queue() and tg3_tx_avail() to check the ring index. If it is not strictly ordered, the tx queue can be stopped forever. This improves performance by about 3% with 2 ports running bi-directional 64-byte packets.

With Remote Packet Steering or multiqueue NIC and appropriate IRQ affinities, we can distribute trafic on available cpus, per session. (all RX packets for a given flow is handled by a given cpu) Some legacy applications being not SMP friendly, one way to scale a server is to run multiple copies of them. Instead of randomly choosing an instance, we can use the cpu number as a key so that softirq handler for a whole instance is running on a single cpu, maximizing cache effects in TCP/UDP stacks. Using NAT for example, a four ways machine might run four copies of server application, using a separate listening port for each instance, but still presenting an unique external port : iptables -t nat -A PREROUTING -p tcp --dport 80 -m cpu --cpu 0 \ -j REDIRECT --to-port 8080 iptables -t nat -A PREROUTING -p tcp --dport 80 -m cpu --cpu 1 \ -j REDIRECT --to-port 8081 iptables -t nat -A PREROUTING -p tcp --dport 80 -m cpu --cpu 2 \ -j REDIRECT --to-port 8082 iptables -t nat -A PREROUTING -p tcp --dport 80 -m cpu --cpu 3 \ -j REDIRECT --to-port 8083 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>

This patch has been tested with a development snapshot of conntrackd and the new clause `TCPWindowTracking' that allows to perform strict TCP window tracking recovery across fail-overs. With this patch, we don't update the receiver's window until it's not initiated. We require this to perform a successful recovery.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lvs sctp protocol handler is incorrectly invoked ip_vs_app_pkt_out Since there's no sctp helpers at present, it does the same thing as ip_vs_app_pkt_in.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | postpone the checksum calculation, then if the output NIC supports checksum offloading, we can utlize it. And though the output NIC doesn't support checksum offloading, but we'll mangle this packet, this can free us from updating the checksum, as the checksum calculation occurs later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the fragments are sent in order in most of OSes, such as Windows, Darwin and FreeBSD, it is likely the new fragments are at the end of the inet_frag_queue. In the fast path, we check if the skb at the end of the inet_frag_queue is the prev we expect. Signed-off-by: Changli Gao <xiaosuo@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
