2023-10-10device: move Queue{In,Out}boundElement Mutex to container typeJordan Whited
Queue{In,Out}boundElement locking can contribute to significant overhead via sync.Mutex.lockSlow() in some environments. These types are passed throughout the device package as elements in a slice, so move the per-element Mutex to a container around the slice.

2023-10-10device: distribute crypto work as slice of elementsJordan Whited
After reducing UDP stack traversal overhead via GSO and GRO, runtime.chanrecv() began to account for a high percentage (20% in one environment) of perf samples during a throughput benchmark. The individual packet channel ops with the crypto goroutines was the primary contributor to this overhead. Updating these channels to pass vectors, which the device package already handles at its ends, reduced this overhead substantially, and improved throughput. The iperf3 results below demonstrate the effect of this commit between two Linux computers with i5-12400 CPUs. There is roughly ~13us of round trip latency between them. The first result is with UDP GSO and GRO, and with single element channels.

2023-10-10conn, device: use UDP GSO and GRO on LinuxJordan Whited
StdNetBind probes for UDP GSO and GRO support at runtime. UDP GSO is dependent on checksum offload support on the egress netdev. UDP GSO will be disabled in the event sendmmsg() returns EIO, which is a strong signal that the egress netdev does not support checksum offload.

2023-03-24conn: fix StdNetEndpoint data race by dynamically allocating endpointsJordan Whited
In 9e2f386 ("conn, device, tun: implement vectorized I/O on Linux"), the Linux-specific Bind implementation was collapsed into StdNetBind. This introduced a race on StdNetEndpoint from getSrcFromControl() and setSrcControl(). Remove the sync.Pool involved in the race, and simplify StdNetBind's receive path to allocate StdNetEndpoint on the heap instead, with the intent for it to be cleaned up by the GC, later. This essentially reverts ef5c587 ("conn: remove the final alloc per packet receive"), adding back that allocation, unfortunately. This does slightly increase resident memory usage in higher throughput scenarios. StdNetBind is the only Bind implementation that was using this Endpoint recycling technique prior to this commit. This is considered a stop-gap solution, and there are plans to replace the allocation with a better mechanism.

If RIO is unavailable, NewWinRingBind() falls back to StdNetBind. StdNetBind uses x/net/ipv{4,6}.PacketConn for sending and receiving datagrams, specifically via the {Read,Write}Batch methods. These methods are unimplemented on Windows and will return runtime errors as a result. Additionally, only Linux benefits from these x/net types for reading and writing, so we update StdNetBind to fall back to the standard library net package for all platforms other than Linux.

2023-03-10conn: set SO_{SND,RCV}BUF to 7MB on the Bind UDP socketJordan Whited
The conn.Bind UDP sockets' send and receive buffers are now being sized to 7MB, whereas they were previously inheriting the system defaults. The system defaults are considerably small and can result in dropped packets on high speed links. By increasing the size of these buffers we are able to achieve higher throughput in the aforementioned case. The iperf3 results below demonstrate the effect of this commit between two Linux computers with 32-core Xeon Platinum CPUs @ 2.9Ghz. There is roughly ~125us of round trip latency between them. The first result is from commit 792b49c which uses the system defaults, e.g. net.core.{r,w}mem_max = 212992. The TCP retransmits are correlated with buffer full drops on both sides.

All platforms now fall under conn.StdNetBind, except for Windows, which remains in conn.WinRingBind, which still needs to be adjusted to handle multiple packets. Also refactor sticky sockets support to eventually be applicable on platforms other than just Linux. However Linux remains the sole platform that fully implements it for now.
