The way I currently do things - merge the latest major release on top of the existing #next and then start applying the new #next patches - does leave the SELinux tree a bit behind when it comes to other subsystems, but it does at least include all of the SELinux relevant patches. I'll admit it isn't perfect, but it seems to work reasonably well for SELinux development, and it was the process used by the previous SELinux maintainer. > > While I hate to split my development branch from the #next branch, it > > seems > > I don't want that either ... > > > like that is the only way to accomplish both a reasonably current and > > stable development tree and get the patches into linux-next.

Sort of, I would basically create a new #next branch for linux-next which would be created fresh from the latest -rc1 and I would cherry-pick the patches for linux-next from my development branch. It would be a bit of a mess to be honest, but I'm trying to reconcile the SELinux development needs/wants with the linux-next needs/wants. > At the core, what is in linux-next should just be exactly what will be > merged by your upstream. That has been, and remains the goal for me as well. However, there have been a number of problems with this in the past, even excluding the latest merge window; I believe these past problems are what you are seeing now. I am hopeful that these issues are behind us now, at least for the most part. > My real point here is that that is not what has happened recently.

This issue has been solved with James a few months ago, this merge window was actually on track to go off without a problem, and it sorta did, but there were some out-of-band issues which caused some confusion in the linux-security world. Let's try to move on a bit, discussing why the SELinux #next branch has some cruft in it doesn't help us resolve things since we all acknowledge there were problems for a while that should now be resolved ... Stephen, assuming for a moment that I created a fresh branch, based against 3.15, and then added the SELinux patches for 3.16 (basically the few new patches that were in the ole #next branch) would that serve as a reasonable basis for a new SELinux #next branch? Around the -rc5/6/7 timeframe I would send a pull request to James to pull from this next branch into the Linux Security branch for 3.17. Once 3.16 is released, I would merge that into this new #next branch and continue with the next round of patches. FYI, more or less, the above is the process we've settled upon for all of the trees that get accumulated into the Linux Security tree. -- paul moore www.paul-moore.com -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
