Ethox

Ethox is a standalone network stack for user-space networking and unikernel systems with a focus on speeed and stability. Less so but also possibly useful for bare-metal microcontrollers.

As part of the consistent performance promises, Ethox restricts itself to not perform internal allocation but integrate well enough to allow the user to choose to perform them nonetheless. It targets stable and nightly Rust only, and does not aim to be backwards compatible to previous stable releases.

Features

The initial feature set will be eth+(ipv4|ipv6)+udp, targetting tcp as a stretch goal. arp and icmp will also be adopted, in some form along the way.

License

Ethox is distributed under the GPLv3. Code contributions are only accepted under waiver of copyright, at the moment, to allow freely choosing other licensing options further down the road. These conditions may be opened up a bit in the future.

A significant portion of the original network code comes from smoltcp, copyright whitequark@whitequark.org, and reproduced and modified here under the terms allowed by its 0-clause BSD license. It may have changed a lot by the time you read this.
