patternihaandClaude Opus 5.5 6b0f06fb2b TUN inbound: Handle weak host send and forwarding on the outbound interface on Windows
Windows ignores the binding of autoOutboundsInterface (IP_UNICAST_IF) when
the outbound interface has weak host send or forwarding on for an IP version
routed to the TUN: Xray's own connections then go into the TUN, from that
interface's address, and stall.

While the TUN runs, weak host send is turned off on that interface for those
IP versions, and turned on again when it stops or another interface takes
over. Forwarding, which Mobile Hotspot and Internet Connection Sharing need,
cannot be turned off without breaking them, so it is reported instead: the
TUN does not start while it is on, and an error is logged when it comes on
later.

Bundled Third-Party Components Redistribution

Certain optional features dynamically load third-party components. These optional components are separate works distributed under their own licenses, and are bundled into the ZIP package for ease of use. Users may replace these components under the licenses from these components.

These components include:

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
