Fix this by finding the real netdev and processing the notifications for vlan netdevs. Fixes: 915cc7ac0f8e ("RDMA/irdma: Add miscellaneous utility definitions") Link: https://lore.kernel.org/r/20220225163211.127-2-shiraz.saleem@intel.com Signed-off-by: Mustafa Ismail Signed-off-by: Shiraz Saleem Reviewed-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe Signed-off-by: Sasha Levin --- diff --git a/drivers/infiniband/hw/irdma/utils.c b/drivers/infiniband/hw/irdma/utils.c index feebfe6..fee179f 100644 --- a/drivers/infiniband/hw/irdma/utils.c +++ b/drivers/infiniband/hw/irdma/utils.c @@ -150,31 +150,35 @@ int irdma_inetaddr_event(struct notifier_block *notifier, unsigned long event, void *ptr) { struct in_ifaddr *ifa = ptr; - struct net_device *netdev = ifa->ifa_dev->dev; + struct net_device *real_dev, *netdev = ifa->ifa_dev->dev; struct irdma_device *iwdev; struct ib_device *ibdev; u32 local_ipaddr; - ibdev = ib_device_get_by_netdev(netdev, RDMA_DRIVER_IRDMA); + real_dev = rdma_vlan_dev_real_dev(netdev); + if (!real_dev) + real_dev = netdev; + + ibdev = ib_device_get_by_netdev(real_dev, RDMA_DRIVER_IRDMA); if (!ibdev) return NOTIFY_DONE; iwdev = to_iwdev(ibdev); local_ipaddr = ntohl(ifa->ifa_address); ibdev_dbg(&iwdev->ibdev, - "DEV: netdev %p event %lu local_ip=%pI4 MAC=%pM\n", netdev, - event, &local_ipaddr, netdev->dev_addr); + "DEV: netdev %p event %lu local_ip=%pI4 MAC=%pM\n", real_dev, + event, &local_ipaddr, real_dev->dev_addr); switch (event) { case NETDEV_DOWN: - irdma_manage_arp_cache(iwdev->rf, netdev->dev_addr, + irdma_manage_arp_cache(iwdev->rf, real_dev->dev_addr, &local_ipaddr, true, IRDMA_ARP_DELETE); - irdma_if_notify(iwdev, netdev, &local_ipaddr, true, false); + irdma_if_notify(iwdev, real_dev, &local_ipaddr, true, false); irdma_gid_change_event(&iwdev->ibdev); break; case NETDEV_UP: case NETDEV_CHANGEADDR: - irdma_add_arp(iwdev->rf, &local_ipaddr, true, netdev->dev_addr); - irdma_if_notify(iwdev, netdev, &local_ipaddr, true, true); + irdma_add_arp(iwdev->rf, &local_ipaddr, true, real_dev->dev_addr); + irdma_if_notify(iwdev, real_dev, &local_ipaddr, true, true); irdma_gid_change_event(&iwdev->ibdev); break; default: @@ -196,32 +200,36 @@ int irdma_inet6addr_event(struct notifier_block *notifier, unsigned long event, void *ptr) { struct inet6_ifaddr *ifa = ptr; - struct net_device *netdev = ifa->idev->dev; + struct net_device *real_dev, *netdev = ifa->idev->dev; struct irdma_device *iwdev; struct ib_device *ibdev; u32 local_ipaddr6[4]; - ibdev = ib_device_get_by_netdev(netdev, RDMA_DRIVER_IRDMA); + real_dev = rdma_vlan_dev_real_dev(netdev); + if (!real_dev) + real_dev = netdev; + + ibdev = ib_device_get_by_netdev(real_dev, RDMA_DRIVER_IRDMA); if (!ibdev) return NOTIFY_DONE; iwdev = to_iwdev(ibdev); irdma_copy_ip_ntohl(local_ipaddr6, ifa->addr.in6_u.u6_addr32); ibdev_dbg(&iwdev->ibdev, - "DEV: netdev %p event %lu local_ip=%pI6 MAC=%pM\n", netdev, - event, local_ipaddr6, netdev->dev_addr); + "DEV: netdev %p event %lu local_ip=%pI6 MAC=%pM\n", real_dev, + event, local_ipaddr6, real_dev->dev_addr); switch (event) { case NETDEV_DOWN: - irdma_manage_arp_cache(iwdev->rf, netdev->dev_addr, + irdma_manage_arp_cache(iwdev->rf, real_dev->dev_addr, local_ipaddr6, false, IRDMA_ARP_DELETE); - irdma_if_notify(iwdev, netdev, local_ipaddr6, false, false); + irdma_if_notify(iwdev, real_dev, local_ipaddr6, false, false); irdma_gid_change_event(&iwdev->ibdev); break; case NETDEV_UP: case NETDEV_CHANGEADDR: irdma_add_arp(iwdev->rf, local_ipaddr6, false, - netdev->dev_addr); - irdma_if_notify(iwdev, netdev, local_ipaddr6, false, true); + real_dev->dev_addr); + irdma_if_notify(iwdev, real_dev, local_ipaddr6, false, true); irdma_gid_change_event(&iwdev->ibdev); break; default: @@ -243,14 +251,18 @@ int irdma_net_event(struct notifier_block *notifier, unsigned long event, void *ptr) { struct neighbour *neigh = ptr; + struct net_device *real_dev, *netdev = (struct net_device *)neigh->dev; struct irdma_device *iwdev; struct ib_device *ibdev; __be32 *p; u32 local_ipaddr[4] = {}; bool ipv4 = true; - ibdev = ib_device_get_by_netdev((struct net_device *)neigh->dev, - RDMA_DRIVER_IRDMA); + real_dev = rdma_vlan_dev_real_dev(netdev); + if (!real_dev) + real_dev = netdev; + + ibdev = ib_device_get_by_netdev(real_dev, RDMA_DRIVER_IRDMA); if (!ibdev) return NOTIFY_DONE;
