* | vlan: Don't propagate flag changes on down interfaces.Matthijs Kooijman2011-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When (de)configuring a vlan interface, the IFF_ALLMULTI ans IFF_PROMISC flags are cleared or set on the underlying interface. So, if these flags are changed on a vlan interface that is not up, the flags underlying interface might be set or cleared twice. Only propagating flag changes when a device is up makes sure this does not happen. It also makes sure that an underlying device is not set to promiscuous or allmulti mode for a vlan device that is down. Signed-off-by: Matthijs Kooijman <matthijs@stdin.nl> Signed-off-by: David S.

* net: consolidate and fix ethtool_ops->get_settings callingJiri Pirko2011-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does several things: - introduces __ethtool_get_settings which is called from ethtool code and from drivers as well. Put ASSERT_RTNL there. - dev_ethtool_get_settings() is replaced by __ethtool_get_settings() - changes calling in drivers so rtnl locking is respected. In iboe_get_rate was previously ->get_settings() called unlocked. This fixes it. Also prb_calc_retire_blk_tmo() in af_packet.c had the same problem. Also fixed by calling __dev_get_by_index() instead of dev_get_by_index() and holding rtnl_lock for both calls. - introduces rtnl_lock in bnx2fc_vport_create() and fcoe_vport_create() so bnx2fc_if_create() and fcoe_if_create() are called locked as they are from other places. - use __ethtool_get_settings() in bonding code Signed-off-by: Jiri Pirko <jpirko@redhat.com> v2->v3: -removed dev_ethtool_get_settings() -added ASSERT_RTNL into __ethtool_get_settings() -prb_calc_retire_blk_tmo - use __dev_get_by_index() and lock around it and __ethtool_get_settings() call v1->v2: add missing export_symbol Reviewed-by: Ben Hutchings <bhutchings@solarflare.com> [except FCoE bits] Acked-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | It's after all necessary to do reset headers here. The reason is we cannot depend that it gets reseted in __netif_receive_skb once skb is reinjected. For incoming vlanids without vlan_dev, vlan_do_receive() returns false with skb != NULL and __netif_reveive_skb continues, skb is not reinjected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no software fallback implemented for SCTP or FCoE checksumming, and so it should not be passed on by software devices like bridge or bonding. For VLAN devices, this is different. First, the driver for underlying device should be prepared to get offloaded packets even when the feature is disabled (especially if it advertises it in vlan_features). Second, devices under VLANs do not get replaced without tearing down the VLAN first. This fixes a mess I accidentally introduced while converting bonding to ndo_fix_features.

Otherwise the vlan header will not be properly put on the packet in the case of vlan header accelleration. As we remove the check from vlan_check_reorder_header rename it vlan_reorder_header to keep the naming clean. Fix up the skb->pkt_type early so we don't look at the packet after adding the vlan tag, which guarantees we don't goof and look at the wrong field. Use a simple if statement instead of a complicated switch statement to decided that we need to increment rx_stats for a multicast packet. Hopefully at somepoint we will just declare the case where VLAN_FLAG_REORDER_HDR is cleared as unsupported and remove the code. Until then this keeps it working correctly. Signed-off-by: Eric W.

In batch mode, unregister_netdevice_queue() doesn’t immediately call vlan_dev_stop(). Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | vlan: remove one synchronize_net() callEric Dumazet2011-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At VLAN dismantle phase, unregister_vlan_dev() makes one synchronize_net() call after vlan_group_set_device(grp, vlan_id, NULL). This call can be safely removed because we are calling unregister_netdevice_queue() to queue device for deletion, and this process needs at least one rcu grace period to complete.

* | net: vlan: make non-hw-accel rx path similar to hw-accelJiri Pirko2011-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now there are 2 paths for rx vlan frames. When rx-vlan-hw-accel is enabled, skb is untagged by NIC, vlan_tci is set and the skb gets into vlan code in __netif_receive_skb - vlan_hwaccel_do_receive. For non-rx-vlan-hw-accel however, tagged skb goes thru whole __netif_receive_skb, it's untagged in ptype_base hander and reinjected This incosistency is fixed by this patch. Vlan untagging happens early in __netif_receive_skb so the rest of code (ptype_all handlers, rx_handlers) see the skb like it was untagged by hw.
