Hey Dmitry,
The below patch is now in net.git and in Linus' tree. It adds a
network namespace deletion notifier, which does some things that
impact the logic of the interface and involves a little bit of object
lifetime management. You'll see at the very bottom I added a test case
to rule out the
Before, we took a reference to the creating netns if the new netns was
different. This caused issues with circular references, with two
wireguard interfaces swapping namespaces. The solution is to rather not
take any extra references at all, but instead simply invalidate the
creating netns pointer
