A companhia de seguros GEICO lan\u00e7ou uma vers\u00e3o preliminar da ferramenta TuxTape, que permite a implementa\u00e7\u00e3o de sua pr\u00f3pria infraestrutura para criar, compilar e entregar patches ao vivo para o kernel Linux. Os patches ao vivo permitem aplicar corre\u00e7\u00f5es ao kernel Linux em tempo real, sem reiniciar ou parar o sistema. O c\u00f3digo do projeto \u00e9 escrito em Rust e distribu\u00eddo sob a licen\u00e7a Apache 2.0. <\/p>\n

Patches ao vivo para corre\u00e7\u00e3o de vulnerabilidades s\u00e3o fornecidos por empresas como Red Hat, Oracle, Canonical e SUSE para suas distribui\u00e7\u00f5es, mas a \u00fanica parte aberta \u00e9 a ferramenta de baixo n\u00edvel para trabalhar com patches, enquanto os pr\u00f3prios patches s\u00e3o gerados em segredo. As distribui\u00e7\u00f5es Gentoo e Debian tentaram desenvolver projetos abertos como elivepatch e linux-livepatching, mas o primeiro est\u00e1 abandonado h\u00e1 6 anos, enquanto o segundo parou na fase de cria\u00e7\u00e3o de um prot\u00f3tipo de teste. <\/p>\n

O TuxTape visa organizar o funcionamento de um sistema pr\u00f3prio para a cria\u00e7\u00e3o e entrega de patches ao vivo, independente de fornecedores externos e adapt\u00e1vel a qualquer kernel Linux, e n\u00e3o apenas para pacotes com o kernel de distribui\u00e7\u00f5es espec\u00edficas. O TuxTape pode gerar patches ao vivo compat\u00edveis com a ferramenta kpatch, desenvolvida pela Red Hat (al\u00e9m do kpatch existem ferramentas semelhantes: kGraft da SUSE, Ksplice da Oracle e o livepatch universal). Os patches s\u00e3o formados na forma de m\u00f3dulos de kernel carreg\u00e1veis, que substituem fun\u00e7\u00f5es no kernel, utilizando o subsistema ftrace para redirecionar para novas fun\u00e7\u00f5es inclu\u00eddas no m\u00f3dulo.

\"O<\/center> <\/p>\n

O TuxTape pode rastrear informa\u00e7\u00f5es sobre corre\u00e7\u00f5es de vulnerabilidades no kernel Linux, publicadas na lista de discuss\u00e3o linux-cve-announce e no reposit\u00f3rio Git, classificar vulnerabilidades por grau de severidade, determinar a aplicabilidade a kernels Linux suportados e gerar patches ao vivo com base em patches comuns para os ramos LTS do kernel. A aplicabilidade dos patches originais \u00e9 avaliada atrav\u00e9s da profila\u00e7\u00e3o das compila\u00e7\u00f5es do kernel. Patches com vulnerabilidades que n\u00e3o afetam o kernel alvo s\u00e3o ignorados. <\/p>\n

O TuxTape inclui um sistema para rastrear novas vulnerabilidades no kernel, um construtor de banco de dados de patches e vulnerabilidades, servidor<\/a> para armazenar metadados, um sistema de gerenciamento de compila\u00e7\u00e3o do kernel, um compilador de kernel, um gerador de patches, um arquivo de patches, um cliente para receber patches para hosts finais e uma interface interativa para gerenciar a cria\u00e7\u00e3o de patches ao vivo.

\"O<\/center> <\/p>\n

O desenvolvimento est\u00e1 em fase de prot\u00f3tipo experimental. Para os testes iniciais, foram sugeridos: tuxtape-cve-parser para analisar informa\u00e7\u00f5es sobre vulnerabilidades e construir um banco de dados com patches; tuxtape-server com a implementa\u00e7\u00e3o da interface gRPC para servi\u00e7os que geram patches; tuxtape-kernel-builder para compilar o kernel em uma configura\u00e7\u00e3o espec\u00edfica e formar um perfil de compila\u00e7\u00e3o; tuxtape-dashboard \u2014 interface de console para revisar e criar live-patches com base em patches de origem, obtidos do tuxtape-server.
