2019-09-02Remove duplicated file in pkg/tcpip/link/rawfile.Haibo Xu
The blockingpoll_unsafe.go was copied to blockingpoll_noyield_unsafe.go during merging commit 7206202bb9439499. If it still stay here, it would cause build errors on non-amd64 platform.

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.

2018-10-10Enforce message size limits and avoid host calls with too many iovecsMichael Pratt
Currently, in the face of FileMem fragmentation and a large sendmsg or recvmsg call, host sockets may pass > 1024 iovecs to the host, which will immediately cause the host to return EMSGSIZE. When we detect this case, use a single intermediate buffer to pass to the kernel, copying to/from the src/dst buffer. To avoid creating unbounded intermediate buffers, enforce message size checks and truncation w.r.t. the send buffer size. The same functionality is added to netstack unix sockets for feature parity.

2018-08-21Build PCAP file with atomic blocking writesIan Gudger
The previous use of non-blocking writes could result in corrupt PCAP files if a partial write occurs. Using (*os.File).Write solves this problem by not allowing partial writes. This change does not increase allocations (in one path it actually reduces them), but does add additional copying. PiperOrigin-RevId: 209652974 Change-Id: I4b1cf2eda4cfd7f237a4245aceb7391b3055a66c
