I added the commit introducing map redirects as the origin of the problem which is v4.14-rc1. The code is a bit different there it seems to work similar.
What stable tree(s) is this for? Just 6.6.y? Why not older ones?
I didn't say just v6.6.y. The commit introducing the problem is in v4.14-rc1 so I would say all the way down for the supported trees. Just let me know if it does not apply for some of the older kernel.
Greg, feel free to decide if this is worth a CVE.
That's not how CVEs are assigned :)
If you want one, please read the in-tree documentation we have for that.
I don't need one but it is tempting to go through the new process :). If it does not make your handling here easier (since you have two different patches for one issue) there is no need for it from my side.
Thank you.
thanks,
