"Rely" is a strong word, I can adapt if they're going away, but I've been using them so far, as in (slightly simplified):
$ cd patches/upstream/ $ wget https://cdn.kernel.org/pub/linux/kernel/v5.x/patch-5.2.9.xz $ xz -d patch-5.2.9.xz $ wget https://www.kernel.org/pub/linux/kernel/v5.x/stable-review/patch-5.2.10-rc1.... $ gunzip patch-5.2.10-rc1.gz $ vim ../series $ quilt ...
I can switch to importing the quilt queue with some sed magic (and I already do that, if interesting or just a larger amounts of patches are queuing up for more than a day or two), but using the -rc patches has been convenient in that semi-manual workflow, also to make sure to really get and test the formal -rc patch, rather than something inbetween.
An easy way to generate a patch is to just use the git.kernel.org web interface. A patch for 5.2.10-rc1 would be: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/p...
Personally this patch upload story sounded to me like a pre-git era artifact...
Given that we no longer do patches for Linus's -rc releases for the past few years, maybe it is time to move to do the same for the stable releases to be consistent.
Or tarballs? Why do we generate tarballs (and go through kup)? git.kernel.org already does it for us.
As I mentioned yesterday, but writing it down here for posterity, there's a number of reasons.
First off, the release process doesn't require kup for when a "real" release happens, that's all now donw on git.kernel.org with a process involving a signed note and some other fun backend stuff. We are working on expanding that in the future with some other signature validation as well, to make it easier to verify tarballs are "correct" as what we do today is a bit different than other projects.
I think that I made it read like I want to remove tarballs altogether. That's not the case: I just want to get rid of the magical signed note process.
That "signed note process" is _way_ better than what we used to do.
The way I understand it, we generate tarballs twice: once during the magical signed note process, and once by the git interface. I'm just suggesting we reduce that down to happen once.
How about we make it even better, we never generate it at all!
That's how the "signed note" process works, the only thing that does the tarball generation is in the kernel.org infrastructure itself, when it receives a properly signed note. I never create it locally or anywhere else and we do not use 'kup' anymore for the process either.
Right now you can fetch tarballs from two different links on kernel.org. For example, a 5.2.9 tarball is available at:
- https://mirrors.edge.kernel.org/pub/linux/kernel/v5.x/linux-5.2.9.tar.xz
- https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/snapshot/li...
Can't we symlink one to the other?
Those are two different hosts/cdn/mirrors/etc. So no, I do not think we can at all without a bunch of work on the code that runs git.kernel.org. But I could be wrong, I don't know that side of the process all that much.
I suggest you look at Konstantin's Kernel Recipes talk from a few years ago that describes how a release happens on the kernel.org side. The only change from his talk to what we do today is that I no longer do 'kup' at all, but instead kick it off with a signed git note.
As for the tarball itself, it's still needed for the same reasons we do so on Linus's releases:
- distros use these. Don't want all Gentoo users hammering on git.kernel.org for their updated builds, that's a huge waste.
We can just place git.kernel.org generated tarballs (for some repos) on the CDN, no?
That's how it kind of happens already, but not quite, see the presentation above for all of the gory details.
