2015-10-15switchdev: assert rtnl mutex when going over lower netdevsJiri Pirko1-4/+11

2015-10-15switchdev: introduce possibility to defer obj_add/delJiri Pirko2-20/+81
Similar to the attr usecase, the caller knows if he is holding RTNL and is in atomic section. So let the called to decide the correct call variant. This allows drivers to sleep inside their ops and wait for hw to get the operation status. Then the status is propagated into switchdev core. This avoids silent errors in drivers.

2015-10-15switchdev: allow caller to explicitly request attr_set as deferredJiri Pirko3-66/+46
Caller should know if he can call attr_set directly (when holding RTNL) or if he has to defer the att_set processing for later. This also allows drivers to sleep inside attr_set and report operation status back to switchdev core. Switchdev core then warns if status is not ok, instead of silent errors happening in drivers.

Emil changes the ixgbe driver to disable LRO by default in favor or GRO. Mark provides two changes for ixgbe, first fixes a semaphore issue when a reset never completes, it is necessary to retake the semaphore before returning. Jesse fixes up a missing function header comment variable reference. Then enables ethtool priv flags to control flow director at runtime. Neerav changes several i40e error messages to debug only since the messages were printing when there was no functional issue and were meant for debug only. Catherine changes the i40e driver to make only X722 support 100M SGMII, since it is the only device to actually support it. Anjali modifies the i40e/i40evf driver to add writeback on ITR offload support for X722 since the device has a way to work around the descriptor writeback issue. Mitch cleans up obsolete code. Also reduces the i40evf init time by shortening up the delays in the init task to aid in performance in load/unload tests and mitigates DMAR errors in VF enable/disable tests. Shannon modifies i40e to allow flow director sideband when the device is in MFP mode and only has one partition enabled, since we still have plenty of interrupts for managing the flow director activity. Also cleaned up flow director ATR control in debugfs since the priv flag has been added to our ethtool interface. Makes several general code cleanups of redundant or unnecessary code for i40e. ==================== Signed-off-by: David S. Miller <[email protected]>

Shorten up the delays in the init task, allowing the VF driver to initialize faster. This aids performance in load/unload tests and mitigates DMAR errors in VF enable/disable tests with absurdly short delays. In the real world, the VF driver will come up more quickly. The original values were set conservatively based on what we expected from the firmware in terms of performance. Now that the driver is in use and we know how well firmware responds to our requests, we can shorten these delays.

2015-10-15netfilter: nfnetlink_log: consolidate check for instance in nfulnl_recv_config()Pablo Neira Ayuso1-23/+5
This patch consolidates the check for valid logger instance once we have passed the command handling: The config message that we receive may contain the following info: 1) Command only: We always get a valid instance pointer if we just created it. In case that the instance is being destroyed or the command is unknown, we jump to exit path of nfulnl_recv_config(). This patch doesn't modify this handling. 2) Config only: In this case, the instance must always exist since the user is asking for configuration updates. If the instance doesn't exist this returns -ENODEV. 3) No command and no configs are specified: This case is rare. The user is sending us a config message with neither commands nor config options. In this case, we have to check if the instance exists and bail out otherwise. Before this patch, it was possible to send a config message with no command and no config updates for an unexisting instance without triggering an error. So this is the only case that changes.

2015-10-14net/mlx4_core: Replace VF zero mac with random mac in mlx4_coreJack Morgenstein5-12/+32
By design, when no default MAC addresses are set in the Hypervisor for VFs, the VFs are passed zero-macs. When such a MAC is received by the VF, it generates a random MAC address and registers that MAC address with the Hypervisor. This random mac generation is currently done in the mlx4_en module. There is a problem, though, if the mlx4_ib module is loaded by a VF before the mlx4_en module. In this case, for RoCE, mlx4_ib will see the un-replaced zero-mac and register that zero-mac as part of QP1 initialization. Having a zero-mac in the port's MAC table creates problems for a Baseboard Management Console. The BMC occasionally sends packets with a zero-mac destination MAC. If there is a zero-mac present in the port's MAC table, the FW will send such BMC packets to the host driver rather than to the wire, and BMC will stop working. To address this problem, we move the replacement of zero-mac addresses with random-mac addresses to procedure mlx4_slave_cap(), which is part of the driver startup for VFs, and is before activation of mlx4_ib and mlx4_en. As a result, zero-mac addresses will never be registered in the port MAC table by the driver. In addition, when mlx4_en does initialize the net device, it needs to set the NET_ADDR_RANDOM flag in the netdev structure if the address was randomly generated. This is done so that udev on the VM does not create a new device name after each VF probe (VM boot and such). To accomplish this, we add a per-port flag in mlx4_dev which gets set whenever mlx4_core replaces a zero-mac with a randomly-generated mac. This flag is examined when mlx4_en initializes the net-device.

This patch implement the pci_error_handlers for mlx5_core which allow the driver to recover from PCI error. Once an error is detected in the PCI, the mlx5_pci_err_detected is called and it: 1) Marks the device to be in 'Internal Error' state. 2) Dispatches an event to the mlx5_ib to flush all the outstanding cqes with error. 3) Returns all the on going commands with error. 4) Unloads the driver. Afterwards, the FW is reset and mlx5_pci_slot_reset is called and it enables the device and restore it's pci state. If the later succeeds, mlx5_pci_resume is called, and it loads the SW stack.

2015-10-14tipc: move fragment importance field to new header positionJon Paul Maloy1-2/+2
In commit e3eea1eb47a ("tipc: clean up handling of message priorities") we introduced a field in the packet header for keeping track of the priority of fragments, since this value is not present in the specified protocol header. Since the value so far only is used at the transmitting end of the link, we have not yet officially defined it as part of the protocol. Unfortunately, the field we use for keeping this value, bits 13-15 in in word 5, has turned out to be a poor choice; it is already used by the broadcast protocol for carrying the 'network id' field of the sending node. Since packet fragments also need to be transported across the broadcast protocol, the risk of conflict is obvious, and we see this happen when we use network identities larger than 2^13-1. This has escaped our testing because we have so far only been using small network id values. We now move this field to bits 0-2 in word 9, a field that is guaranteed to be unused by all involved protocols.
