O provedor de VPN Mullvad, que desenvolve o navegador web Mullvad Browser e fornece infraestrutura para o servi\u00e7o Mozilla VPN, apresentou o projeto GotaTun, com a implementa\u00e7\u00e3o do protocolo VPN WireGuard, escrita na linguagem Rust e funcionando no espa\u00e7o do usu\u00e1rio. O c\u00f3digo do projeto \u00e9 distribu\u00eddo sob a licen\u00e7a BSD. A empresa Mullvad j\u00e1 integrou o GotaTun no cliente VPN para a plataforma Android e no pr\u00f3ximo ano planeja migrar os aplicativos para desktops e iOS. <\/p>\n

O GotaTun \u00e9 um fork da ferramenta BoringTun, desenvolvida pela Cloudflare e utilizada no aplicativo WARP. O GotaTun se destaca do BoringTun por oferecer suporte completo \u00e0 plataforma Android, otimiza\u00e7\u00f5es de desempenho e recursos adicionais para prote\u00e7\u00e3o da privacidade. <\/p>\n

O GotaTun integra suporte \u00e0 tecnologia DAITA (Defense Against AI-guided Traffic Analysis) para prote\u00e7\u00e3o contra a an\u00e1lise de tr\u00e1fego criptografado realizada utilizando ferramentas baseadas em sistemas de aprendizado de m\u00e1quina. A DAITA normaliza o tamanho dos pacotes enviados, mistura um tr\u00e1fego de fundo aleat\u00f3rio e distorce padr\u00f5es t\u00edpicos de fluxos de dados. O GotaTun tamb\u00e9m implementou um modo Multihop, permitindo acessar VPN<\/a>-servidores n\u00e3o diretamente, mas atrav\u00e9s de uma s\u00e9rie de n\u00f3s de tr\u00e2nsito, o que, por exemplo, possibilita organizar a passagem do tr\u00e1fego por rotas mais otimizadas. <\/p>\n

Para aumentar a performance, o GotaTun implementou processamento multithread e adotou uma estrat\u00e9gia de gerenciamento de mem\u00f3ria em modo zero-copy, sem buffer intermedi\u00e1rio, utilizando apenas o buffer fornecido originalmente. <\/p>\n

Anteriormente, nos aplicativos da empresa Mullvad, utilizava-se um fork da implementa\u00e7\u00e3o do WireGuard em Go \u2014 wireguard-go, ampliado com suporte a DAITA e Multihop. De acordo com estat\u00edsticas do Google, 85% de todos os relat\u00f3rios de falhas do cliente Android da Mullvad enviados pelos usu\u00e1rios estavam relacionados ao c\u00f3digo wireguard-go. Por isso, a empresa decidiu substituir a implementa\u00e7\u00e3o do WireGuard por uma op\u00e7\u00e3o mais confi\u00e1vel. <\/p>\n

A implementa\u00e7\u00e3o em Rust foi escolhida porque o aplicativo Mullvad VPN \u00e9 escrito nessa linguagem, exceto pelo c\u00f3digo wireguard-go, cuja intera\u00e7\u00e3o foi organizada por meio de uma interface FFI (foreign function interface) complicada e que utiliza blocos unsafe. Na vers\u00e3o do cliente Android da Mullvad, publicada no final de novembro, a implementa\u00e7\u00e3o wireguard-go foi substitu\u00edda por GotaTun, resolvendo assim problemas de confiabilidade \u2014 em compara\u00e7\u00e3o com vers\u00f5es anteriores, a m\u00e9trica que reflete o n\u00famero de falhas mudou de 0,40% para 0,01%.
