This one is tricky, we did the switch to github.com/inetaf/tcpproxy in commit 600910c, but this caused a regression in gvproxy/podman, so we reverted it in #386
The replace inet.af/tcpproxy => github.com/inetaf/tcpproxy v0.0.0-20221017015627-91f861402626 in go.mod is supposed to paper over this issue, but given you opened this PR, this must not be enough?

Thanks, replace is enough for now, but I hope that eventually gvisor-tap-vsock can switch to the latest upstream (or just fork it under non-.af TLD)

@cfergeau The problem with replace is that it only affects the main module; it is not inherited just by using gvisor-tap-vsock and it's go.mod:

exclude and replace directives only operate on the current (“main”) module. exclude and replace directives in modules other than the main module are ignored when building the main module. The replace and exclude statements, therefore, allow the main module complete control over its own build, without also being subject to complete control by dependencies.
-- Go Wiki: Go Modules

So every program using gvisor-tap-vsock, even if just indirectly, will have to copy the replace directive into their own go.mod file to have any effect.

Alternative: mv vendor/inet.af/tcpproxy/tcpproxy.go to pkg/tcpproxy/tcpproxy.go
