Samsung's KSMBD server hitting primetime has several significant implications

The next release of the Linux kernel, 6.6 [will] include the KSMBD in-kernel server for the SMB networking protocol, developed by Samsung's Namjae Jeon.

it has faced considerable security testing and as a result it is no longer marked as experimental.

It's compatible with existing Samba configuration files.

But 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 adds enhanced security, considerably better performance for both single and multi-thread read/write, better stability, and higher compatibility. In the end, hopefully, this KSMBD will also mean easier share setups in Linux without having to jump through the same hoops one must with the traditional Samba setup.

    KSMBD is also important in that placing such core server functionality right inside the kernel represents a significant potential attack surface for crackers. As one comment on Hacker News said "Unless this is formally proven or rewritten in a safer language, you'll have to pay me in solid gold to use such a CVE factory waiting to happen."

    Words to live by.

      I guess if you're just running it in a VM with a passthrough storage device with nothing else running in the VM that could be okay.
