Signed-off-by: Serge Hallynserge.hal...@canonical.com --- While playing with natty and maverick containers I noticed at startup the udev events are broadcast to all the udev daemons running on the host and the containers. IMO that should not occur. I am looking at the lib/kobject_udev.c and net/af_netlink.c and I suspect there is a bug with the broadcast filtering of the events ... When I was testing on natty I was pretty sure i only saw syslog entries for the container, not the host - but I may not have been looking for the right thing. What exactly did you see? For example, if you use the command udevadm --trigger in a container, you will see the udev daemons receiving the events in both the host and in the container. That's what I mean - I was doing 'udevadm --trigger' in a container, but based just on the PIDs of udev processes telling syslog that they were handling events, it seemed to me that they must all be in a container. Were you going based on syslog, or did you have another way to get udevd to tell you it had processed events ? I got the udevd log error (creation is prevented by the cgroup) on each console of all the containers and I straced the host udevd daemon. -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
