This series, along with pseudo-related fixes, enables:
- optional copy of all routes from selected interface in outer
namespace, to (hopefully!) fix the issue reported by Callum at:
https://github.com/containers/podman/issues/18539
- optional copy of all addresses, mostly for consistency. It doesn't,
however, enable assignment of multiple addresses in the sense
requested at:
https://bugs.passt.top/show_bug.cgi?id=47
because the addresses still need to be present on the host, and
the "outer" address isn't selected depending on the address used
inside the container
- operation without a gateway address, to (again, hopefully) support
usage of Wireguard endpoints established outside the container,
https://bugs.passt.top/show_bug.cgi?id=49
I tested the single functionalities introduced here, but I didn't
try to reproduce the setups where the issues were reported, so some
help with testing is definitely fundamental here. Thanks.
