patternihaandClaude Opus 5.5 3d830eea02 TUN inbound: Don't set IP_BOUND_IF on IPv6 sockets on Darwin
Since #7173, a failed interface binding fails the dial. On Darwin (macOS
and iOS), setinterface fell through from IPV6_BOUND_IF to IP_BOUND_IF on
IPv6 sockets, which Darwin rejects with EINVAL. So every UDP dial failed,
as Go opens a dual-stack IPv6 socket for it, and so did TCP to IPv6. TCP to
IPv4 uses an IPv4 socket and kept working. Before #7173 the error was only
logged.

IPV6_BOUND_IF binds the whole socket, so on a dual-stack socket it covers
its IPv4 traffic as well. Set only the option of the socket's family, as
sockopt_darwin.go already does for sockopt.interface. The new test binds
each kind of socket to lo0.

Linux, Android and FreeBSD bind with socket-level options (SO_BINDTODEVICE,
SO_SETFIB) that don't depend on the IP version. On Windows, the related case
of an adapter without IPv4 or IPv6 is handled in #7214.

Fixes #7228

One-line Compilation

Windows (PowerShell)

$env:CGO_ENABLED=0
go build -o xray.exe -trimpath -buildvcs=false -ldflags="-s -w -buildid=" -v ./main

Linux / macOS

CGO_ENABLED=0 go build -o xray -trimpath -buildvcs=false -ldflags="-s -w -buildid=" -v ./main

Reproducible Releases

Make sure that you are using the same Go version, and remember to set the git commit id (7 bytes):

CGO_ENABLED=0 go build -o xray -trimpath -buildvcs=false -gcflags="all=-l=4" -ldflags="-X github.com/xtls/xray-core/core.build=REPLACE -s -w -buildid=" -v ./main

For Android:

GOOS=android GOARCH=arm64 CGO_ENABLED=1 CC=/path/to/aarch64-linux-android24-clang go build -o xray -trimpath -buildvcs=false -gcflags="all=-l=4" -ldflags="-X github.com/xtls/xray-core/core.build=REPLACE -s -w -buildid= -checklinkname=0" -v ./main
GOOS=android GOARCH=amd64 CGO_ENABLED=1 CC=/path/to/x86_64-linux-android24-clang go build -o xray -trimpath -buildvcs=false -gcflags="all=-l=4" -ldflags="-X github.com/xtls/xray-core/core.build=REPLACE -s -w -buildid= -checklinkname=0" -v ./main

If you are compiling a 32-bit MIPS/MIPSLE target, use this command instead:

CGO_ENABLED=0 go build -o xray -trimpath -buildvcs=false -gcflags="-l=4" -ldflags="-X github.com/xtls/xray-core/core.build=REPLACE -s -w -buildid=" -v ./main
