KSMBD Finally Reaches a Stable State

KSMBD (the kernel SMB daemon) is the in-kernel module, developed by Samsung that implements the SMB/CIFS protocol for sharing files and folders over a network. The SMB 3 server could take the place of the traditional Samba software.

KSMBD was originally merged for Linux 5.15 but was tagged as experimental. That came about in 2021, and it has taken some time to get KSMBD to a state that was considered stable. That time has come, and KSMBD is planned for Linux kernel 6.6.

Why is KSMBD important? First off, it promises considerable performance gains and better support for modern features such as Remote Direct Memory Access (RDMA). KSMBD also supports a number of features such as multiple dialects (SMB 2.1, SMB 3.0, SMB 3.1), oplock cache mechanism, compound requests, ACL, and DCE/RPC.
