While I understand you did not intend to mislead DaveM and the netdev folks with the v2 patchset, your failure to properly manage the patchset's metadata *did* mislead them and as a result a patchset with serious concerns from the SELinux side was merged. You need to revert this patchset while we continue to discuss, develop, and verify a proper fix that we can all agree on. If you decide not to revert this patchset I will work with DaveM to do it for you, and that is not something any of us wants.I would prefer a follow-up rathewr than a revert at this point. Please work with Xin to come up with a fix that works for both of you.We are working with Xin (see this thread), but you'll notice there is still not a clear consensus on the best path forward. The only thing I am clear on at this point is that the current code in linux-next is *not* something we want from a SELinux perspective. I don't like leaving known bad code like this in linux-next for more than a day or two so please revert it, now. If your policy is to merge substantive non-network subsystem changes into the network tree without the proper ACKs from the other subsystem maintainers, it would seem reasonable to also be willing to revert those patches when the affected subsystems request it. I understand that if a patchset is being ignored you might feel the need to act without an explicit ACK, but this particular patchset wasn't even a day old before you merged into the netdev tree. Not to mention that the patchset was posted during the second day of the merge window, a time when many maintainers are busy testing code, sending pull requests to Linus, and generally managing merge window fallout.Hi Paul, It's applied on net tree, I think mostly because I posted this on net.git tree. Also, it's well related to the network part and affects SCTP protocol quite a lot.
Yes, I know it is in the net tree, that is how it made its way into linux-next. I wouldn't have merged it yet, and if not me who else would have merged it beside the netdev folks? Am I misunderstanding your comment?
I wanted to post it on selinux tree: pcmoore/selinux.git, but I noticed the

selinux: add a SELinux specific README.md
DO NOT SUBMIT UPSTREAM
Then I thought this tree was no longer active, sorry about that.Like many kernel trees the default/main branch for the SELinux tree doesn't contain anything useful, for the SELinux tree (and audit for that matter) it is basically just the most recent major/minor tag from Linus tree with a single tree specific README.md file patch so that the GitHub mirror has a pretty landing page and a canonical reference for how the tree is maintained. * https://github.com/SELinuxProject/selinux-kernel The general approach to the SELinux tree, as documented in the README.md, is to do all of the linux-next work in the selinux/next branch with the stable work happening in the selinux/stable-X.Y branches. FWIW, once we've resolved things I would be happy to have the patchset live in the SELinux tree as opposed to the netdev tree. -- paul moore www.paul-moore.com
