From Linus Torvalds <> Date Sun, 28 Jan 2018 13:52:49 -0800 Subject Linux 4.15 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.



Half the changes in the last week were misc driver stuff (gpu, input,

networking) with the other half being a mix of networking, core kernel

and arch updates (mainly x86). But all of it is tiny.



So at least we had one good week. This obviously was not a pleasant

release cycle, with the whole meltdown/spectre thing coming in in the

middle of the cycle and not really gelling with our normal release

cycle. The extra two weeks were obviously mainly due to that whole

timing issue.



Also, it is worth pointing out that it's not like we're "done" with

spectre/meltdown. There is more work pending (arm, spectre-v1, misc

details), and perhaps equally importantly, to actually get the biggest

fix for the indirect branch mitigations, you need not just the kernel

updates, you need to have a compiler with support for the "retpoline"

indirect branch model.



You can do



cat /sys/devices/system/cpu/vulnerabilities/spectre_v2



and if you don't have a compiler that supports the retpoline

mitigations, you'll get:



Vulnerable: Minimal generic ASM retpoline



because only the assembly code (not the C code) will have the

retpoline mitigation. So keep that in mind.



Anyway, while spectre/meltdown has obviously been the big news this

release cycle, it's worth noting that we obviously had all the

*normal* updates going on too, and the work everywhere else didn't

just magically stop, even if some developers have been distracted by

CPU issues. In the *big* picture, 4.15 looks perfectly normal, with

two thirds of the full 4.15 patch being about drivers, and even the

arch updates are dominated by the arm DTS diffs, not by CPU bug

mitigation.



So the news cycle notwithstanding, the bulk of the 4.15 work is all

the regular plodding "boring" stuff. And I mean that in the best

possible way. It may not be glamorous and get the headlines, but it's

the bread and butter of kernel development, and is in many ways the

really important stuff.



Go forth and play with it, things actually look pretty good despite everything.



And obviously this also means that the merge window for 4.16 is open.

I already have a number of pull requests pending that I will start

merging tomorrow. Hopefully we'll have a _normal_ and entirely boring

release cycle for 4.16. Because boring really is good.
