John Seager, vice-presidente da Canonical e l\u00edder t\u00e9cnico do projeto Ubuntu, anunciou a inten\u00e7\u00e3o de integrar no lan\u00e7amento de outono do Ubuntu 26.10 o servidor NTP ntpd-rs, desenvolvido em Rust e j\u00e1 aplicado na infraestrutura da Autoridade Certificadora Let's Encrypt. O projeto ntpd-rs ser\u00e1 o terceiro componente, ap\u00f3s Rust Coreutils e sudo-rs, integrado ao Ubuntu como parte da iniciativa para melhorar a qualidade do ambiente de sistema atrav\u00e9s da entrega de software inicialmente projetado com foco em seguran\u00e7a, confiabilidade e corre\u00e7\u00e3o. <\/p>\n

Est\u00e1 em discuss\u00e3o tamb\u00e9m a substitui\u00e7\u00e3o da biblioteca zlib pela zlib-rs e a utiliza\u00e7\u00e3o do pacote Sequoia no lugar do GnuPG no gerenciador de pacotes APT. O pacote ntpd-rs pretende ser utilizado por padr\u00e3o como servidor<\/a> um cliente de sincroniza\u00e7\u00e3o de tempo preciso, que eventualmente substituir\u00e1 os pacotes atualmente utilizados, como chrony, linuxptp e possivelmente gpsd. O plano proposto para implementa\u00e7\u00e3o prev\u00ea a entrega da vers\u00e3o atual do pacote ntpd-rs nos reposit\u00f3rios do Ubuntu 26.10 como uma op\u00e7\u00e3o para testes. No Ubuntu 27.04, planejam usar ntpd-rs por padr\u00e3o como um servidor e cliente unificado com suporte aos protocolos NTP, NTS e PTP. <\/p>\n

O projeto ntpd-rs \u00e9 desenvolvido pela Trifecta Tech Foundation, que tamb\u00e9m \u00e9 respons\u00e1vel pela cria\u00e7\u00e3o da ferramenta sudo-rs j\u00e1 integrada ao Ubuntu. A Canonical financiar\u00e1 o desenvolvimento de novos recursos e melhorias de seguran\u00e7a no ntpd-rs. Entre outras coisas, o ntpd-rs pretende integrar as contribui\u00e7\u00f5es do projeto Statime, que desenvolve a implementa\u00e7\u00e3o do protocolo PTP (Precision Time Protocol) na linguagem Rust, para unificar o suporte aos protocolos atuais de sincroniza\u00e7\u00e3o de tempo em um \u00fanico pacote e utilizar ntpd-rs n\u00e3o apenas como substituto do chrony, mas tamb\u00e9m do linuxptp. <\/p>\n

Dentre as funcionalidades adicionais a serem implementadas no ntpd-rs antes de seu lan\u00e7amento, est\u00e3o a implementa\u00e7\u00e3o dos protocolos gPTP e CSPTP, suporte ao socket IP do gpsd, modo multithread para servidores NTP, possibilidade de uso em modo multi-homed, cria\u00e7\u00e3o de perfis de isolamento com base em AppArmor e seccomp, fornecimento de ferramentas para teste e avalia\u00e7\u00e3o de desempenho, melhorias relacionadas ao registro de logs e configura\u00e7\u00e3o, e aprimoramento da ferramenta ntp-cli. <\/p>\n

Al\u00e9m de projetos conjuntos com a Trifecta Tech Foundation, a Canonical tamb\u00e9m se tornou um dos participantes 'dourados' da Rust Foundation, que se dedica ao desenvolvimento e ao suporte da linguagem Rust e do ecossistema relacionado. Juntamente com a Canonical, que se tornou o \u00fanico participante dourado, o financiamento-chave para o desenvolvimento do Rust \u00e9 fornecido por 6 participantes platina \u2014 Google, Microsoft, Amazon, ARM, Meta e Huawei. A contribui\u00e7\u00e3o de um participante dourado \u00e9 de 150 mil d\u00f3lares por ano, enquanto a de um participante platina \u00e9 de 325 mil d\u00f3lares. <\/p>\n

Al\u00e9m disso, \u00e9 importante mencionar o an\u00fancio de Julian Andres Klode da Canonical, que acompanha o projeto APT, sobre a inten\u00e7\u00e3o de reduzir o n\u00famero de analisadores no carregador GRUB, com o objetivo de diminuir a superf\u00edcie de ataque. No Ubuntu 26.10, \u00e9 proposto remover do conjunto assinado digitalmente do GRUB o suporte aos formatos de imagem jpeg e png, tabelas de parti\u00e7\u00e3o part_apple e a capacidade de usar os sistemas de arquivos btrfs, hfsplus, xfs e zfs para a parti\u00e7\u00e3o \/boot. Al\u00e9m disso, planejam remover o suporte ao uso de parti\u00e7\u00f5es LVM, md-raid (exceto raid1) e parti\u00e7\u00f5es criptografadas LUKS na \/boot. <\/p>\n

Ressalta-se que no instalador do Ubuntu, o sistema de arquivos ext4 \u00e9 sempre utilizado para \/boot, e outros sistemas n\u00e3o s\u00e3o testados e representam uma amea\u00e7a \u00e0 verifica\u00e7\u00e3o do modo de inicializa\u00e7\u00e3o verificado, devido \u00e0 identifica\u00e7\u00e3o peri\u00f3dica de vulnerabilidades no GRUB (1, 2, 3, 4, 5, 6, 7). Quanto \u00e0 remo\u00e7\u00e3o do suporte para a criptografia da parti\u00e7\u00e3o \/boot, essa opera\u00e7\u00e3o \u00e9 considerada in\u00fatil (security by obscurity) \u2014 neste contexto, \u00e9 importante garantir a integridade na parti\u00e7\u00e3o \/boot, o que \u00e9 realizado com TPM FDE, em vez de ocultar dados. Em parti\u00e7\u00f5es diferentes de \/boot, como antes, ser\u00e1 poss\u00edvel usar LUKS, LVM e MD-RAID. Restri\u00e7\u00f5es tamb\u00e9m n\u00e3o ser\u00e3o aplicadas ao inicializar fora do modo UEFI Secure Boot.
