Third-Party Notices

Rocket LAN bundles a handful of third-party components in the shipped application. The notable ones, the bundled GPLv2 network driver, Discord's Social SDK, and the bundled fonts, are reproduced below. The exhaustive Rust-crate and npm-package lists ship inside the application and are reachable from Settings → Third-Party Notices → Full third-party notices.

tap-windows6, virtual network adapter driver

Rocket LAN bundles and installs OpenVPN's tap-windows6 NDIS 6 TAP virtual network driver. It is the layer-2 virtual Ethernet adapter over which Rocket LAN carries Rocket League's native LAN traffic.

License

The tap-windows6 driver is licensed under the GNU General Public License, version 2. The full GPLv2 text is in the file COPYING in the upstream repository: github.com/OpenVPN/tap-windows6/blob/master/COPYING.

The driver is a separate, pre-signed kernel component. It runs in its own address space and is not linked into Rocket LAN's user-space application, so GPLv2 does not extend to Rocket LAN's own source code. Redistributing the unmodified signed driver binary does, however, carry GPLv2's obligation to make the corresponding source available.

Corresponding source code

Rocket LAN ships the tap-windows6 driver unmodified. The complete corresponding source code for the redistributed version (9.27.0) is the upstream tagged release, publicly and permanently available at:

github.com/OpenVPN/tap-windows6/releases/tag/9.27.0

The vendored header tap-windows.h is additionally available under the MIT license; it is included only as developer reference for the driver's IOCTL constants and is not compiled into Rocket LAN.

Signing

tap0901.sys and tap0901.cat are signed by Microsoft through the Windows Hardware Compatibility Program. Because the driver is WHQL-signed, Rocket LAN does not need its own kernel-driver signing certificate or a WHQL submission.

Discord Social SDK, Discord's identity, friends, and presence library

Rocket LAN integrates with Discord (friends list, identities, invites, rich presence) through Discord's Social SDK, a closed-source, vendored C/C++ library called from Rust through hand-written FFI bindings. The shipped application bundles its redistributable runtime.

The Discord Social SDK is provided by Discord to developers for the purpose of integrating applications with Discord's social features. It is vendored unmodified and used under, and remains governed by, Discord's Developer Terms: discord.com/developers/docs/discord-social-sdk/overview.

The SDK's own bundled open-source components (its C++ dependencies) are disclosed in its own notice file in the application's source tree; see the in-app full notices for the pointer.

Bundled fonts, SIL Open Font License

Rocket LAN ships two typeface families as application assets. The font files themselves are licensed under the SIL Open Font License, Version 1.1 (OFL-1.1), which requires the copyright notice and license to be reproduced with any redistribution of the Font Software:

The full SIL Open Font License v1.1 text for both fonts is reproduced verbatim in the in-app full notices screen, under the @fontsource/space-grotesk and @fontsource/jetbrains-mono entries.
