Xin Long 48606bb1ee netlink: reset extack earlier in netlink_rcv_skb ... [ Upstream commit cd443f1e91 ] Move up the extack reset/initialization in netlink_rcv_skb, so that those 'goto ack' will not skip it. Otherwise, later on netlink_ack may use the uninitialized extack and cause kernel crash. Fixes: cbbdf8433a ("netlink: extack needs to be reset each time through loop") Reported-by: syzbot+03bee3680a37466775e7@syzkaller.appspotmail.com Signed-off-by: Xin Long <lucien.xin@gmail.com> Acked-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.
