patternihaandClaude Opus 5.5 de02da553a TUN inbound: Block IPv4 too when it is not routed to the TUN on Windows
autoSystemWfpBlockLeak blocked IPv6 when the TUN had no IPv6 address or
no IPv6 route, and IPv4 never: with only IPv6 routed to the TUN, IPv4
went around it. Now each IP version is blocked when no route of it leads
to the TUN, except for loopback, DHCP, IPv6 neighbor and multicast
listener discovery, and Xray itself.

Addresses no longer count: without one of a version in gateway, Windows
gives the TUN a link-local one itself (fe80:: at once, 169.254.x.x after
some seconds), and what is routed to the TUN goes through it with that,
so a TUN with IPv6 routes but no IPv6 address had its IPv6 blocked for
nothing.

Tested on Windows 11, elevated: with only IPv6 routed, other programs'
IPv4 is denied, while loopback, a DHCP renew of Wi-Fi and Xray still
work; without gateway, IPv4 and IPv6 routed to the TUN enter it from
169.254.x.x and fe80::.

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
