Foi proposta uma nova implementa\u00e7\u00e3o de servidor de arquivos utilizando o protocolo SMB3 para inclus\u00e3o na pr\u00f3xima vers\u00e3o do n\u00facleo do Linux. O servidor \u00e9 apresentado como um m\u00f3dulo do n\u00facleo ksmbd e complementa o c\u00f3digo do cliente SMB que j\u00e1 estava dispon\u00edvel. Destaca-se que, ao contr\u00e1rio do servidor SMB que opera no espa\u00e7o do usu\u00e1rio, a implementa\u00e7\u00e3o em n\u00edvel de n\u00facleo \u00e9 mais eficiente em termos de desempenho, consumo de mem\u00f3ria e integra\u00e7\u00e3o com as capacidades avan\u00e7adas do n\u00facleo. <\/p>\n

Entre as capacidades do ksmbd, destaca-se o suporte aprimorado para a tecnologia de cache distribu\u00eddo de arquivos (SMB leases) em sistemas locais, que permite uma redu\u00e7\u00e3o significativa do tr\u00e1fego. No futuro, est\u00e1 planejada a adi\u00e7\u00e3o de novas funcionalidades, como o suporte a RDMA (\"smbdirect\"), bem como extens\u00f5es do protocolo relacionadas ao fortalecimento da confiabilidade da criptografia e \u00e0 verifica\u00e7\u00e3o por meio de assinaturas digitais. \u00c9 destacado que tais extens\u00f5es s\u00e3o muito mais f\u00e1ceis de implementar em um formato compacto e bem otimizado. servidor<\/a>funcionando em n\u00edvel de n\u00facleo, do que em um pacote Samba. <\/p>\n

Vale destacar que o ksmbd n\u00e3o pretende substituir completamente o pacote Samba, que n\u00e3o se limita \u00e0s fun\u00e7\u00f5es de um servidor de arquivos servidor<\/a> e oferece ferramentas abrangendo servi\u00e7os de seguran\u00e7a, LDAP e controlador de dom\u00ednio. A implementa\u00e7\u00e3o do servidor de arquivos no Samba \u00e9 multiplataforma e \u00e9 projetada para aplica\u00e7\u00f5es mais amplas, o que dificulta a otimiza\u00e7\u00e3o para alguns ambientes Linux, como o firmware de dispositivos com recursos limitados. <\/p>\n

O ksmbd \u00e9 considerado n\u00e3o como um produto separado, mas sim como uma extens\u00e3o de alto desempenho pronta para uso em dispositivos embarcados, que pode ser integrada, se necess\u00e1rio, com as ferramentas e bibliotecas do Samba. Por exemplo, j\u00e1 foi acordado com os desenvolvedores do Samba o uso de arquivos de configura\u00e7\u00e3o e atributos estendidos (xattrs) compat\u00edveis com smbd no ksmbd, facilitando a transi\u00e7\u00e3o entre smbd e ksmbd e vice-versa. <\/p>\n

Os principais autores do c\u00f3digo do ksmbd s\u00e3o Namjae Jeon da Samsung e Hyunchul Lee da LG. O suporte ao ksmbd no n\u00facleo ser\u00e1 gerenciado por Steve French da Microsoft (que trabalhou muitos anos na IBM), o mantenedor da subcamada CIFS\/SMB2\/SMB3 no n\u00facleo do Linux e um veterano da equipe de desenvolvedores do Samba, que fez uma contribui\u00e7\u00e3o significativa para implementa\u00e7\u00e3o do suporte aos protocolos SMB\/CIFS no Samba e no Linux.
