2019-06-06Add multi-fd support to fdbased endpoint.Bhasker Hariharan
This allows an fdbased endpoint to have multiple underlying fd's from which packets can be read and dispatched/written to. This should allow for higher throughput as well as better scalability of the network stack as number of connections increases. Updates #231 PiperOrigin-RevId: 251852825
2019-05-21Refactor fdbased endpoint dispatcher code.Bhasker Hariharan
This is in preparation to support an fdbased endpoint that can read/dispatch packets from multiple underlying fds. Updates #231 PiperOrigin-RevId: 249337074 Change-Id: Id7d375186cffcf55ae5e38986e7d605a96916d35

2019-04-18netstack: use a proper network protocol to set gso.L3HdrLenAndrei Vagin
It is possible to create a listening socket which will accept IPv4 and IPv6 connections. In this case, we set IPv6ProtocolNumber for all accepted endpoints, even if they handle IPv4 connections. This means that we can't use endpoint.netProto to set gso.L3HdrLen. PiperOrigin-RevId: 244227948 Change-Id: I5e1863596cb9f3d216febacdb7dc75651882eef1

2019-03-28netstack/fdbased: add generic segmentation offload (GSO) supportAndrei Vagin
The linux packet socket can handle GSO packets, so we can segment packets to 64K instead of the MTU which is usually 1500. Here are numbers for the nginx-1m test: runsc: 579330.01 [Kbytes/sec] received runsc-gso: 1794121.66 [Kbytes/sec] received runc: 2122139.06 [Kbytes/sec] received and for tcp_benchmark: $ tcp_benchmark --duration 15 --ideal [ 4] 0.0-15.0 sec 86647 MBytes 48456 Mbits/sec $ tcp_benchmark --client --duration 15 --ideal [ 4] 0.0-15.0 sec 2173 MBytes 1214 Mbits/sec $ tcp_benchmark --client --duration 15 --ideal --gso 65536 [ 4] 0.0-15.0 sec 19357 MBytes 10825 Mbits/sec PiperOrigin-RevId: 240809103 Change-Id: I2637f104db28b5d4c64e1e766c610162a195775a
2019-01-29Use recvmmsg() instead of readv() to read packets from NIC.Bhasker Hariharan
This should reduce the number of syscalls required to process packets significantly and improve throughputs. PiperOrigin-RevId: 231366886 Change-Id: I8b38077262bf9c53176bc4a94b530188d3d7c0ca
2018-11-14Rename incorrectly named (dst, src) arguments in DeliverNetworkPacket prototypeBert Muthalaly
...to (remote, local), reflecting the (correct) names in the implementation of DeliverNetworkPacket (see tcpip/stack/nic.go). Also trim the names in DeliverNetworkPacket and elsewhere to avoid stuttering; since the type is tcpip.LinkAddress, there's no need to include "LinkAddr" in the parameter names. Note that every callsite passes arguments in the order (src, dst). PiperOrigin-RevId: 221514396 Change-Id: I3637454ad0d6e62a19e4dcbc2a16493798bd0f09

2018-09-19Pass local link address to DeliverNetworkPacketBert Muthalaly
This allows a NetworkDispatcher to implement transparent bridging, assuming all implementations of LinkEndpoint.WritePacket call eth.Encode with header.EthernetFields.SrcAddr set to the passed Route.LocalLinkAddress, if it is provided.

2018-09-05Update {LinkEndpoint,NetworkEndpoint}#WritePacket to take a VectorisedViewBert Muthalaly
Makes it possible to avoid copying or allocating in cases where DeliverNetworkPacket (rx) needs to turn around and call WritePacket (tx) with its VectorisedView. Also removes the restriction on having VectorisedViews with multiple views in the write path. PiperOrigin-RevId: 211728717 Change-Id: Ie03a65ecb4e28bd15ebdb9c69f05eced18fdfcff
