Feng Tang ec4fe4bcc5 i40iw: Avoid panic when handling the inetdev event ... There is a panic reported that on a system with x722 ethernet, when doing the operations like: # ip link add br0 type bridge # ip link set eno1 master br0 # systemctl restart systemd-networkd The system will panic "BUG: unable to handle kernel null pointer dereference at 0000000000000034", with call chain: i40iw_inetaddr_event notifier_call_chain blocking_notifier_call_chain notifier_call_chain __inet_del_ifa inet_rtm_deladdr rtnetlink_rcv_msg netlink_rcv_skb rtnetlink_rcv netlink_unicast netlink_sendmsg sock_sendmsg __sys_sendto It is caused by "local_ipaddr = ntohl(in->ifa_list->ifa_address)", while the in->ifa_list is NULL. So add a check for the "in->ifa_list == NULL" case, and skip the ARP operation accordingly.
