Description Lubomir Rintel 2015-06-01 20:25:58 UTC
Created attachment 1033484 [details] Suggested fix +++ This bug was initially created as a clone of Bug #1203731 +++ ... > To prevent this unfortunate behavior you can of course use user_ns. However > once you go this road note that you are entering another realm of pain with > current user_ns implementation. Not really; works fairly well. One small problem is in the rtnetlink code, where the daemon checks for uid of the originating message, where it should be checking the messages come from kernel (an unprivileged user can now manage his network namespace). Attaching fix.
