* bonding: Support macvlans on top of tlb/rlb mode bondsVlad Yasevich2014-06-043-6/+45
| | | | | | | | | | | | | | | | To make TLB mode work, the patch allows learning packets to be sent using mac addresses assigned to macvlan devices, also taking into an account vlans that may be between the bond and macvlan device. To make RLB work, all we have to do is accept ARP packets for addresses added to the bond dev->uc list. Since RLB mode will take care to update the peers directly with correct mac addresses, learning packets for these addresses do not have be send to switch.

* macvlan: Support bonding eventsVlad Yasevich2014-06-041-0/+7
| | | | | | | | | | | | | | | Bonding and team drivers generate specific events during failover that trigger switch updates. When a macvlan device is configured on top of bonding, we want switches to learn about the macvlan devices as well. This patch adds a handler to macvlan driver to propagate these events to all macvlan devices. We let the generic inetdev event handler do the work. This allows macvlan to operated correctly over active-backup mode bond. Signed-off-by: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* bonding: Turn on IFF_UNICAST_FLT on bond devicesVlad Yasevich2014-06-041-1/+1
| | | | | | | | | | | | | | | Bonding devices manage the unicast filters of the underlying interfaces, but do not turn on IFF_UNICAST_FLT flag. Thus anytime a unicast address is added to the bond, the bond is places in promiscuous mode. Turn on IFF_UNICAST_FLT on the bond device so that the bond does not go into promiscuous mode needlesly. If an underlying device does not support unicast filtering, that device will automaticall enter promiscuous mode already. Signed-off-by: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | Builds on the refactoring of the previous patch to implement multiple queues between xen-netfront and xen-netback. Writes the maximum supported number of queues into XenStore, and reads the values written by the frontend to determine how many queues to use. Ring references and event channels are read from XenStore on a per-queue basis and rings are connected accordingly. Also adds code to handle the cleanup of any already initialised queues if the initialisation of a subsequent queue fails. Signed-off-by: Andrew J.

Emil provides his version 2 fix for the detection of SFP+ capable interfaces. In cases where the driver is loaded while there are no SFP+ modules in cage, the interface was not being detected as SFP capable. Resolve the issue by identifying interfaces with no PHY type set as SFP capable which allows the driver to detect the SFP module when the interface is brought up. In this version 2 of the patch, the 82599 specific check was removed since we only have 82598 devices that are SFP capable. Jacob removes the including of the export header in the ixgbe PTP core, since it is not needed. Renames igb_ptp_enable() to igb_ptp_feature_enable() to better reflect the actual functions purpose. Todd fixes the ethtool loopback test for i354 backplane devices since we do not know what PHY is to be used for the devices, use MAC loopback for ethtool tests. Todd also sets the packet buffer size register defaults for i210 devices. Yongjian Xu removes the check for skb->len being negative or zero since there is never a case where it would be zero or negative for e1000. Manuel Schölling updates e1000 to use the time_after() helper function. v2: Fix indentation on wrapped line in patch 3 of the series based on feedback from David Miller ==================== Signed-off-by: David S.

| * ixgbe: fix detection of SFP+ capable interfacesEmil Tantilov2014-06-032-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In cases where the driver is loaded while there are no SFP+ modules in the cage the interface was not being detected as SFP capable. To account for this the driver called identify_sfp in ixgbe_get_settings to make sure the data is correct. However when there is no SFP+ module in the cage the driver waits for the I2C reads to time out which can take more than a second and will cause issues with tools (like net-snmp) that may poll for that information. This patch resolves the issue by identifying interfaces with no PHY type set as SFP capable which allows the driver to detect the SFP module when the interface is brought up. As result of this we can also remove the identify_sfp call from ixgbe_get_settings. v2: remove the 82599 specific check since we have 82598 devices that are SFP capable.

| * sh_eth: use RNC mode for packet receptionBen Dooks2014-06-032-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current behaviour of the sh_eth driver is not to use the RNC bit for the receive ring. This means that every packet recieved is not only generating an IRQ but it also stops the receive ring DMA as well until the driver re-enables it after unloading the packet. This means that a number of the following errors are generated due to the receive packet FIFO overflowing due to nowhere to put packets: net eth0: Receive FIFO Overflow Since feedback from Yoshihiro Shimoda shows that every supported LSI for this driver should have the bit enabled it seems the best way is to remove the RMCR default value from the per-system data and just write it when initialising the RMCR value. This is discussed in the message (http://www.spinics.net/lists/netdev/msg284912.html). I have tested the RMCR_RNC configuration with NFS root filesystem and the driver has not failed yet. There are further test reports from Sergei Shtylov and others for both the R8A7790 and R8A7791. There is also feedback fron Cao Minh Hiep[1] which reports the same issue in (http://comments.gmane.org/gmane.linux.network/316285) showing this fixes issues with losing UDP datagrams under iperf.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A rmb() is required to ensure that the CQE is not read before it is written by the adapter DMA. PCI ordering rules will make sure the other fields are written before the marker at the end of struct eth_fast_path_rx_cqe but without rmb() a weakly ordered processor can process stale data.

As not every CAN driver supports and initializes the led triggers, checking for the CAN private datastructure with safe_candev_priv() in the notifier chain is not enough. This patch adds a check when CONFIG_CAN_LEDS is enabled and the driver does not support led triggers.

As part of this fix, we refactor the RoCE gid table driver copy, moving it to the mlx4_port_info structure (together with the MAC and VLAN tables). As with the MAC and VLAN tables, we now use a mutex per port for the GID table so that modifying the driver copy and modifying the firmware copy of a port GID table becomes an atomic operation (thus avoiding driver-copy/FW-copy mismatches).

However it didn't set MD_RECOVERY_INTR so ->finish_reshape() would not know that the reshape didn't complete. This only happens when mddev->ro is set and normally reshape threads don't run in that situation. But raid5 and raid10 can start a reshape thread during "run" is the array is in the middle of a reshape. They do this even if ->ro is set. So it is best to set MD_RECOVERY_INTR before abortingg the sync thread, just in case. Though it rare for this to trigger a problem it can cause data corruption because the reshape isn't finished properly. So it is suitable for any stable which the offending commit was applied to.

However in that case MD_RECOVERY_INTR isn't set. If a RESHAPE had been requested, then ->finish_reshape() will be called and it will think the reshape was successful even though nothing happened. Normally a resync will not be requested if ->ro is set, but if an array is stopped while a reshape is on-going, then when the array is started, the reshape will be restarted. If the array is also set read-only at this point, the reshape will instantly appear to success, resulting in data corruption. Consequently, this patch is suitable for any -stable kernel.
