back to article Linux kernel 5.15 released with new NTFS driver plus an LTS sticker slapped on it

Linus Torvalds released version 5.15 of the Linux kernel yesterday with a new NTFS driver, an SMB3 server, and an advanced memory monitor among the features. This version is considered an LTS release. Part of a heatmap generated by DAMON, new in kernel 5.15 Part of a heatmap generated by DAMON, new in kernel 5.15 Torvalds …

      Yep - now declared as LTS, though not an 'ultra' LTS like 5.10, so a shorter projected lifespan. I didn't think they were going to squeeze in another release before New Year! Hopefully this kernel will form the foundation of Ubuntu 22.04 and its offshoots.

    Slightly confused about samba

    I thought that smb was part of the kernel already but obviously I'm wrong. How is it being implemented currently?

        Well, that article was scarily informative. It turns out that my gut-feel about a kernel implementation of the basket-of-holes that is SMB is correct - it's full of security risks. I know they've fixed loads, but at this late stage, we should be down to security researchers finding esoteric corner-cases, not ordinary code-reviewers going "er, where's the tests for this case?".

        Pray $DEITY there's a kernel option to turn this sucker off!

          That was my thought as well. Performance gains at the expense of security is not a trade off I'm willing to make.

          Eh? If you don’t like SMB, don’t use it. It is just kernel loadable modules same as any other.

          This is Linux.

          If you don't want a kernel module, you don't even need to give it hard disk space, let alone actually load it.

          Everything is optional. That's both the joy and the pain.
