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
2019-03-28netstack/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
2019-02-13Add support for using PACKET_RX_RING to receive packets.Bhasker Hariharan
PACKET_RX_RING allows the use of an mmapped buffer to receive packets from the kernel. This should cut down the number of host syscalls that need to be made to receive packets when the underlying fd is a socket of the AF_PACKET type.

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
2018-10-23Track paths and provide a rename hook.Adin Scannell
This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55
2018-07-27stateify: support explicit annotation mode; convert refs and stack packages.Zhaozhong Ni
We have been unnecessarily creating too many savable types implicitly. PiperOrigin-RevId: 206334201 Change-Id: Idc5a3a14bfb7ee125c4f2bb2b1c53164e46f29a8
