Per l'inclusione nel prossimo rilascio del kernel Linux, \u00e8 stata proposta una nuova implementazione del server file che utilizza il protocollo SMB3. Il server \u00e8 realizzato come un modulo del kernel ksmbd e integra il codice del client SMB gi\u00e0 disponibile. Si segnala che, a differenza del server SMB che opera nello spazio utente, l'implementazione a livello di kernel \u00e8 pi\u00f9 efficiente dal punto di vista delle prestazioni, del consumo di memoria e dell'integrazione con le funzionalit\u00e0 avanzate del kernel. <\/p>\n

Tra le caratteristiche di ksmbd spicca un migliorato supporto per la tecnologia di caching distribuito dei file (SMB leases) sui sistemi locali, che consente una significativa riduzione del traffico. In futuro, \u00e8 previsto l'aggiunta di nuove funzionalit\u00e0, come il supporto per RDMA («smbdirect»), oltre ad estensioni del protocollo relative al potenziamento dell'affidabilit\u00e0 della crittografia e alla verifica mediante firme digitali. Si sottolinea che tali estensioni sono molto pi\u00f9 facili da implementare in un sistema compatto e ben ottimizzato. server<\/a>, che opera a livello di kernel, rispetto al pacchetto Samba. <\/p>\n

In questo contesto, ksmbd non si propone come una sostituzione completa del pacchetto Samba, che non si limita alle sole funzionalit\u00e0 di file. server<\/a> e fornisce strumenti che coprono i servizi per garantire la sicurezza, LDAP e il controller del dominio. L'implementazione di un server file in Samba \u00e8 multipiattaforma e progettata per applicazioni pi\u00f9 ampie, il che rende difficile l'ottimizzazione per alcuni ambienti Linux, come i firmware per dispositivi con risorse limitate. <\/p>\n

Ksmbd non \u00e8 visto come un prodotto separato, ma piuttosto come un'estensione ad alte prestazioni e pronta per l'uso su dispositivi embedded, integrabile, se necessario, con strumenti e librerie Samba. Ad esempio, la questione dell'uso di file di configurazione compatibili con smbd e attributi estesi (xattrs) in ksmbd \u00e8 gi\u00e0 stata concordata con gli sviluppatori di Samba, il che semplificher\u00e0 la transizione tra smbd e ksmbd e viceversa. <\/p>\n

I principali autori del codice ksmbd sono Namjae Jeon di Samsung e Hyunchul Lee di LG. La manutenzione di ksmbd all'interno del kernel sar\u00e0 gestita da Steve French di Microsoft (precedentemente ha lavorato per molti anni in IBM), manutentore delle sottosistemi CIFS\/SMB2\/SMB3 nel kernel Linux e da lungo tempo membro del team di sviluppo Samba, che ha dato un contributo significativo nell'implementazione del supporto per i protocolli SMB\/CIFS in Samba e Linux.
