Зеркало Leadaxe/wireguard-go-awg2-lx — сабмодуль ядра sing-box-lx (AmneziaWG). GPLv3.
The Cloudflare "reserved" bytes (1-3) were zeroed unconditionally on every received datagram across all StdNetBind/WinRingBind receive paths. AmneziaWG reads its magic header as LittleEndian.Uint32(packet[padding:]) where padding is s1/s2/s4; with small padding (0-3) the magic overlaps bytes 1-3, so clearing them collapses it out of the ranged h1-h4 window and every packet is dropped (handshake included) — the AWG endpoint never comes up. Plain WG (types 1-4, bytes 1-3 already zero) and large padding are unaffected, which is why it went unnoticed. Gate all five receive clears (bind_std receiveIP, msgx_darwin receiveSingle + makeReceiveMsgX, bind_windows receiveIPv4/v6) behind a new hasReserved() so bytes 1-3 are only touched when a WARP reserved value is actually configured. Send paths already gate on a per-endpoint loaded/non-zero check, so they are left unchanged. The reserved map is populated before the receive goroutines start and never mutated after, so the lock-free read is safe. Tests: awg_stdnetbind_reserved_lx_test.go brings up two Devices over StdNetBind with zero padding (magic in bytes 0-3) and asserts delivery (red before the fix, green after); reserved_gate_lx_test.go pins the hasReserved() gate. |
