[0.8.0] - 2026-07-09

Added

• Device::suspend and Device::resume to pause and resume all tunnel activity. Suspending stops the timers, inbound, and outbound tasks (no keepalives, handshakes, or data), while retaining peers and config. Resuming rebuilds the connection and forces a fresh handshake. Intended for platforms such as iOS where I/O can be cooperatively suspended for lower power use.

Changed

• Replace log with tracing.

Removed

• Remove AsFd implementation for UdpSocket.

Fixed

• Do not update peer endpoint/roam on received cookie replies. This change is made to be consistent with Linux kernel and wireguard-go.
• Continue with IPv4-only UDP transport on Linux when IPv6 sockets are unavailable.

[kasnder]

Investigated — do not merge as-is; recommend deferring. Root cause: gotatun 0.8.0 made UdpSocket's inner an opaque enum (Socket/DisabledIpv6) and removed the public impl AsFd for UdpSocket (was at udp/socket/mod.rs:216 in 0.7.2; the 0.8.0 accessor fn socket() is pub(crate)). There's now no public way to get the fd we hand to Android's VpnService.protect() — our loop-prevention path.

A workaround compiles (bind our own tokio socket, protect it, impl UdpSend/UdpRecv) but regresses gotatun's optimized sendmmsg/recvmmsg+GRO datapath to per-packet I/O — a throughput/battery/radio-wakeup concern for this app. Filed upstream for a public fd accessor: mullvad/gotatun#165. Recommend deferring #632 until that lands. Not included in #637.
