Kernel 4.17 released

[Posted June 4, 2018 by corbet]

Linus has released the 4.17 kernel, which will indeed be called "4.17". "No, I didn't call it 5.0, even though all the git object count numerology was in place for that. It will happen in the not _too_ distant future, and I'm told all the release scripts on kernel.org are ready for it, but I didn't feel there was any real reason for it." Headline features in this release include improved load estimation in the CPU scheduler, raw BPF tracepoints, lazytime support in the XFS filesystem, full in-kernel TLS protocol support, histogram triggers for tracing, mitigations for the latest Spectre variants, and, of course, the removal of support for eight unloved processor architectures.

Just to keep people guessing, I pre-created v5.x, v6.x, v2018.x and v3000.x directories in /pub/linux/kernel/.

modify the filesystem driver to return a different set of fake version number directories for this exact path on each stat, to keep everyone guessing in different and exciting ways.

Kai :) ...but it seems, Linus is bloody ignorant about that and justifiably so.

None of those are over 9000 though.

Wouldn't the natural version after v4.x be v7.x?

Note that: "full in-kernel TLS protocol support"

Well, “full” as in both send and receive. It still doesn't do the key exchange, and still only AES-128-CBC as far as I know.

Key Exchange is pretty complicated compared to encryption so it probably makes sense to do this in userspace. I wonder if this actually helps performance to do it in the kernel, are there benchmarks (post meltdown)?
