Hi all, The question: is there any way to uniquely identify a network namespace in the kernel?
The context: for debugging purposes, I need to log information about network devices. netdev_info() uses the device name to identify the device, however there can be several devices by that name in different namespaces. To know which device the message relates to, I would need to know the namespace in addition to the device name. For all I know, the namespace's name is a user-space thing and the kernel has no idea. But I would at least need some kind of unique identifier to group log message by device. So far I'm using the struct address returned by dev_net() as the unique ID, but leaking kernel addresses to userspace is not recommended. So I am wondering, is there another recommended way to uniquely identify a network namespace in a log message? Thanks, -- Jean Delvare SUSE L3 Support
