PiperOrigin-RevId: 291803499
2020-01-27Expose gonet.NewPacketConn, for parity with gonet.NewConn APIMarek Majkowski
gonet.Conn can be created with both gonet.NewConn and gonet.Dial. gonet.PacketConn was created only by gonet.DialUDP. This prevented us from being able to use PacketConn in udp.NewForwarder() context. This simple constructor - NewPacketConn, allows user to create correct structure from that context.

*net.UDPAddr PacketConn.LocalAddr() already returns *net.UDPAddr correctly.
2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387

2019-02-19Updates tcp_proxy to use an AF_PACKET and veth devices.Bhasker Hariharan
tcp_proxy now uses an AF_PACKET socket as the FD for netstack link layer endpoint instead of a tap device. It also changes the link layer endpoint to use PacketMMap dispatch instead of Readv. This reduces overall cpu and reflects the current runsc setup which uses PacketMMap and also uses veth devices to receive packets. Also fixed a bug in gonet where Read() was not doing coalescing read and would read small amounts at a time. PiperOrigin-RevId: 234714768 Change-Id: Idabf8e600e4512489d3ba441c4096dc74deba5d7

2018-09-28Block for link address resolutionSepehr Raissian
Previously, if address resolution for UDP or Ping sockets required sending packets using Write in Transport layer, Resolve would return ErrWouldBlock and Write would return ErrNoLinkAddress. Meanwhile startAddressResolution would run in background. Further calls to Write using same address would also return ErrNoLinkAddress until resolution has been completed successfully. Since Write is not allowed to block and System Calls need to be interruptible in System Call layer, the caller to Write is responsible for blocking upon return of ErrWouldBlock. Now, when startAddressResolution is called a notification channel for the completion of the address resolution is returned. The channel will traverse up to the calling function of Write as well as ErrNoLinkAddress. Once address resolution is complete (success or not) the channel is closed. The caller would call Write again to send packets and check if address resolution was compeleted successfully or not.
