Linus has released the 4.15 kernel.
“After a release cycle that was unusual in so many (bad) ways, this
last week was really pleasant. Quiet and small, and no last-minute
panics, just small fixes for various issues. I never got a feeling
that I’d need to extend things by yet another week, and 4.15 looks
fine to me.”
Some of the more significant features in this release include:
the long-awaited CPU controller for the
version-2 control-group interface,
significant live-patching improvements,
initial support for the RISC-V architecture,
support for AMD’s secure encrypted virtualization feature, and
the MAP_SYNC mechanism for working
with nonvolatile memory.
This release also, of course, includes mitigations for the Meltdown and Spectre variant-2
vulnerabilities though, as Linus points out in the announcement, the
work of dealing with these issues is not yet done.
