* Added HV Socket known IDs, Dial, bug fixes Added: * Well-know Hyper-V VMIDs for parents, children, and loopback. * VSock interop service GUID. * `Dial()` and `DialContext()` to dial a specific Hyper-V socket at a known address (along with a corresponding `HvsockDialer` struct. Bug fixes: * Dial (and Listen) now properly initialize and set properties of their sockets after ConnectEx (and AcceptEx). * The `socketError` used by `bind` was incorrect, it should be `int32(-1)`, not `uintptr(^0)` * Return errors for `(*HvsockConn) SetDeadline` Created a `sockets` package, currently only with syscalls to `Bind`, `ConnectEx` and `GetSockName`, bypassing `syscall/windows` restrictions on the types that can do so. Signed-off-by: Hamza El-Saawy <hamzaelsaawy@microsoft.com> * PR: error handling bug, rebase, unexport, naming * comments and todos statements * spelling * removed dead code * changed names to be more conventional * unexported socket code * made `(*HvsockDialer) Dial` take `Context`, removed `DialContext` * added default `Dial` function * rebased onto main * cleaned up `Dial(` retry loop Signed-off-by: Hamza El-Saawy <hamzaelsaawy@microsoft.com> * PR: RawSockaddr validation, `.As(` style Signed-off-by: Hamza El-Saawy <hamzaelsaawy@microsoft.com>
