Subject: [PATCH net] ipv4: correctly iterate over the target netns in inet_dump_ifaddr()
A recent change to inet_dump_ifaddr had the function incorrectly iterate
over net rather than tgt_net, resulting in the data coming for the
incorrect network namespace.
Fixes: cdb2f80f1c10 ("inet: use xa_array iterator to implement inet_dump_ifaddr()")
Reported-by: Stéphane Graber <stgraber@...raber.org>
Closes: https://github.com/lxc/incus/issues/892
