socket

Package socket provides a low-level network connection type which integrates with Go's runtime network poller to provide asynchronous I/O and deadline support. MIT Licensed.

This package focuses on UNIX-like operating systems which make use of BSD sockets system call APIs. It is meant to be used as a foundation for the creation of operating system-specific socket packages, for socket families such as Linux's AF_NETLINK, AF_PACKET, or AF_VSOCK. This package should not be used directly in end user applications.

Any use of package socket should be guarded by build tags, as one would also use when importing the syscall or golang.org/x/sys packages.

TestLinuxDialVsockNoListener test failure

OS: Debian sid/amd64 golang: go1.17.8 linux/amd64 github.com/mdlayher/socket: v0.2.2

I am working on updating the version of this library that's packaged for Debian, but the TestLinuxDialVsockNoListener test always fails. I see this failure via go test (below), well as in the schroot environment that is created when building the Debian package. My build setup is a minimal Debian sid install that is running within a privileged LXD container.

Missing error check in socket fallback path

The unix.Socket call in EINVAL or EPROTONOSUPPORT fallback path in socket is missing the error check:

https://github.com/mdlayher/socket/blob/7c9fcbcebf504a63e5d002868c514b6bb97708ba/conn.go#L197-L204

That means if unix.Socket fails with EINVAL or EPROTONOSUPPORT and then fails again, a *Conn will be returned referencing fd=0 / /dev/stdin.
socket: use generics to simplify closure value returns

I started experimenting with this in https://github.com/mdlayher/socket/commit/247e85df156379823e7f10b96c503a87f79a452b.

Eventually we can make a lot of calls return (T, error) from closures to simplify the need to pass variables in and out, and to remove the hassle of dealing with multiple error scopes.

However, since this is a very foundational library and generics are very new, it probably isn't feasible to do this for some time. It'd be possible to add Go 1.18+ shims and duplicate the code, but that doesn't seem great either.
