Pentru a fi inclus\u0103 \u00een urm\u0103toarea versiune a nucleului Linux, a fost propus\u0103 o nou\u0103 implementare a serverului de fi\u0219iere care utilizeaz\u0103 protocolul SMB3. Serverul este realizat sub forma unui modul de nucleu ksmbd \u0219i completeaz\u0103 codul clientului SMB disponibil anterior. Se remarc\u0103 faptul c\u0103, spre deosebire de serverul SMB care func\u021bioneaz\u0103 \u00een spa\u021biul utilizatorului, implementarea la nivelul nucleului este mai eficient\u0103 din punct de vedere al performan\u021bei, consumului de memorie \u0219i integr\u0103rii cu func\u021bionalit\u0103\u021bile avansate ale nucleului. <\/p>\n

Printre func\u021bionalit\u0103\u021bile ksmbd se remarc\u0103 suportul \u00eembun\u0103t\u0103\u021bit pentru tehnologia de cache distribuit de fi\u0219iere (SMB leases) pe sistemele locale, care permite o reducere semnificativ\u0103 a traficului. \u00cen continuare, se preconizeaz\u0103 ad\u0103ugarea unor noi func\u021bionalit\u0103\u021bi, cum ar fi suportul RDMA («smbdirect»), precum \u0219i extensii ale protocolului ce vizeaz\u0103 \u00eembun\u0103t\u0103\u021birea fiabilit\u0103\u021bii cript\u0103rii \u0219i verificarea prin semn\u0103turi digitale. Se observ\u0103 c\u0103 astfel de extensii sunt mult mai u\u0219or de implementat \u00eentr-un sistem compact \u0219i bine optimizat. server<\/a>, care func\u021bioneaz\u0103 la nivelul nucleului, dec\u00e2t \u00een pachetul Samba. <\/p>\n

\u00cen acest context, ksmbd nu \u00ee\u0219i asum\u0103 rolul de a \u00eenlocui complet pachetul Samba, care nu se limiteaz\u0103 doar la func\u021bionalit\u0103\u021bile de fi\u0219iere server<\/a> \u0219i ofer\u0103 un set de instrumente ce acoper\u0103 servicii pentru asigurarea securit\u0103\u021bii, LDAP \u0219i controlul de domeniu. Implementarea serverului de fi\u0219iere \u00een Samba este cross-platform \u0219i destinat\u0103 unor domenii de aplicare mai largi, ceea ce \u00eengreuneaz\u0103 optimizarea pentru anumite medii Linux, cum ar fi firmware-urile pentru dispozitive cu resurse limitate. <\/p>\n

Ksmbd este considerat nu ca un produs separat, ci mai degrab\u0103 ca o extensie de \u00eenalt\u0103 performan\u021b\u0103 \u0219i preg\u0103tit\u0103 pentru utilizare pe dispozitive \u00eencorporate, care poate fi integrat\u0103 cu instrumentele \u0219i bibliotecile Samba. De exemplu, dezvoltatorii Samba au convenit deja s\u0103 utilizeze \u00een ksmbd configura\u021bii de fi\u0219iere compatibile cu smbd \u0219i atribute extinse (xattrs), ceea ce va simplifica tranzi\u021bia de la smbd la ksmbd \u0219i invers. <\/p>\n

Principalele contribu\u021bii la codul ksmbd sunt realizate de Namjae Jeon de la compania Samsung \u0219i Hyunchul Lee de la LG. \u00centre\u021binerea ksmbd \u00een cadrul nucleului va fi gestionat\u0103 de Steve French de la Microsoft (care a lucrat mul\u021bi ani la IBM), mentor al subsistemului CIFS\/SMB2\/SMB3 din nucleul Linux \u0219i participant de lung\u0103 durat\u0103 al echipei de dezvoltare Samba, care a adus o contribu\u021bie semnificativ\u0103 la implementarea suportului pentru protocoalele SMB\/CIFS \u00een Samba \u0219i Linux.
