First, Hi and thanks for all the effort!
At least on Ubuntu latest LTS: As advertised, if a wireguard link
gets created by systemd/networkd, then set into a different net
namespace, all works well.
However, if that namespace is deleted, the link appears to be 'gone
forever'. Other link types reappear in the primary namespace when the
namespace they are in gets deleted. I'm not sure whether the link
retains its 'up' or 'down' state when the namespace it's in gets
deleted and reset to primary. Not a big deal, doesn't happen often.
This is 100% repeatable. Some other answer than 'inaccessible until
the next reboot' would be nice.
Hi,
This behavior is exactly what I would expect. I'm using namespaces to
restrict access to a wireguard link. If the namespace gets destroyed, I
absolutely do not want other programs to have access to the wireguard link.
You can simply re-create the wireguard link to use it again. This may
not be the most convenient for you, but your use case seems to be a bit
unconventional: you are moving and deleting a resource created by
systemd and/or networkd manually. You are mixing automatic and manual
management, so there is a risk of breaking the automatic management.
Alternatively, you could move the interface back before deleting the
namespace.
Kind regards,
