rtnetlink: enable IFLA_IF_NETNSID for RTM_DELLINK
- Backwards Compatibility:
If userspace wants to determine whether RTM_DELLINK supports the
IFLA_IF_NETNSID property they should first send an RTM_GETLINK request
with IFLA_IF_NETNSID on lo. If either EACCESS is returned or the reply
does not include IFLA_IF_NETNSID userspace should assume that
IFLA_IF_NETNSID is not supported on this kernel.
If the reply does contain an IFLA_IF_NETNSID property userspace
can send an RTM_DELLINK with a IFLA_IF_NETNSID property. If they receive
EOPNOTSUPP then the kernel does not support the IFLA_IF_NETNSID property
with RTM_DELLINK. Userpace should then fallback to other means.
- Security:
Callers must have CAP_NET_ADMIN in the owning user namespace of the
target network namespace.
