Pull networking updates from David Miller: "Most notable changes in here: 1) By far the biggest accomplishment, thanks to a large range of contributors, is the addition of multi-send for transmit. This is the result of discussions back in Chicago, and the hard work of several individuals. Now, when the ->ndo_start_xmit() method of a driver sees skb->xmit_more as true, it can choose to defer the doorbell telling the driver to start processing the new TX queue entires. skb->xmit_more means that the generic networking is guaranteed to call the driver immediately with another SKB to send. There is logic added to the qdisc layer to dequeue multiple packets at a time, and the handling mis-predicted offloads in software is now done with no locks held. Finally, pktgen is extended to have a "burst" parameter that can be used to test a multi-send implementation. Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4, virtio_net Adding support is almost trivial, so export more drivers to support this optimization soon. I want to thank, in no particular or implied order, Jesper Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann, David Tat, Hannes Frederic Sowa, and Rusty Russell. 2) PTP and timestamping support in bnx2x, from Michal Kalderon. 3) Allow adjusting the rx_copybreak threshold for a driver via ethtool, and add rx_copybreak support to enic driver. From Govindarajulu Varadarajan. 4) Significant enhancements to the generic PHY layer and the bcm7xxx driver in particular (EEE support, auto power down, etc.) from Florian Fainelli. 5) Allow raw buffers to be used for flow dissection, allowing drivers to determine the optimal "linear pull" size for devices that DMA into pools of pages. The objective is to get exactly the necessary amount of headers into the linear SKB area pre-pulled, but no more. The new interface drivers use is eth_get_headlen(). From WANG Cong, with driver conversions (several had their own by-hand duplicated implementations) by Alexander Duyck and Eric Dumazet. 6) Support checksumming more smoothly and efficiently for encapsulations, and add "foo over UDP" facility. From Tom Herbert. 7) Add Broadcom SF2 switch driver to DSA layer, from Florian Fainelli. 8) eBPF now can load programs via a system call and has an extensive testsuite. Alexei Starovoitov and Daniel Borkmann. 9) Major overhaul of the packet scheduler to use RCU in several major areas such as the classifiers and rate estimators. From John Fastabend. 10) Add driver for Intel FM10000 Ethernet Switch, from Alexander Duyck. 11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric Dumazet. 12) Add Datacenter TCP congestion control algorithm support, From Florian Westphal. 13) Reorganize sk_buff so that __copy_skb_header() is significantly faster.

2014-10-07net: better IFF_XMIT_DST_RELEASE supportEric Dumazet1-0/+8
Testing xmit_more support with netperf and connected UDP sockets, I found strange dst refcount false sharing. Current handling of IFF_XMIT_DST_RELEASE is not optimal. Dropping dst in validate_xmit_skb() is certainly too late in case packet was queued by cpu X but dequeued by cpu Y The logical point to take care of drop/force is in __dev_queue_xmit() before even taking qdisc lock. As Julian Anastasov pointed out, need for skb_dst() might come from some packet schedulers or classifiers. This patch adds new helper to cleanly express needs of various drivers or qdiscs/classifiers. Drivers that need skb_dst() in their ndo_start_xmit() should call following helper in their setup instead of the prior : dev->priv_flags &= ~IFF_XMIT_DST_RELEASE; -> netif_keep_dst(dev); Instead of using a single bit, we use two bits, one being eventually rebuilt in bonding/team drivers. The other one, is permanent and blocks IFF_XMIT_DST_RELEASE being rebuilt in bonding/team. Eventually, we could add something smarter later.

2014-10-05net: Cleanup skb cloning by adding SKB_FCLONE_FREEVijay Subramanian1-3/+4
SKB_FCLONE_UNAVAILABLE has overloaded meaning depending on type of skb. 1: If skb is allocated from head_cache, it indicates fclone is not available. 2: If skb is a companion fclone skb (allocated from fclone_cache), it indicates it is available to be used. To avoid confusion for case 2 above, this patch replaces SKB_FCLONE_UNAVAILABLE with SKB_FCLONE_FREE where appropriate. For fclone companion skbs, this indicates it is free for use. SKB_FCLONE_UNAVAILABLE will now simply indicate skb is from head_cache and cannot / will not have a companion fclone.

2014-10-04qdisc: validate skb without holding lockEric Dumazet1-1/+1
Validation of skb can be pretty expensive : GSO segmentation and/or checksum computations. We can do this without holding qdisc lock, so that other cpus can queue additional packets. Trick is that requeued packets were already validated, so we carry a boolean so that sch_direct_xmit() can validate a fresh skb list, or directly use an old one. Tested on 40Gb NIC (8 TX queues) and 200 concurrent flows, 48 threads host. Turning TSO on or off had no effect on throughput, only few more cpu cycles. Lock contention on qdisc lock disappeared.

2014-10-02udp: Generalize skb_udp_segmentTom Herbert1-2/+24
skb_udp_segment is the function called from udp4_ufo_fragment to segment a UDP tunnel packet. This function currently assumes segmentation is transparent Ethernet bridging (i.e. VXLAN encapsulation). This patch generalizes the function to operate on either Ethertype or IP protocol. The inner_protocol field must be set to the protocol of the inner header. This can now be either an Ethertype or an IP protocol (in a union). A new flag in the skbuff indicates which type is effective. skb_set_inner_protocol and skb_set_inner_ipproto helper functions were added to set the inner_protocol. These functions are called from the point where the tunnel encapsulation is occuring. When skb_udp_tunnel_segment is called, the function to segment the inner packet is selected based on the inner IP or Ethertype. In the case of an IP protocol encapsulation, the function is derived from inet[6]_offloads. In the case of Ethertype, skb->protocol is set to the inner_protocol and skb_mac_gso_segment is called. (GRE currently does this, but it might be possible to lookup the protocol in offload_base and call the appropriate segmenation function directly).

2014-10-01HID: wacom: implement generic HID handling for pen generic devicesBenjamin Tissoires1-0/+2
ISDv4 and v5 are plain HID devices. We can directly implement a generic HID parsing/handling and remove the need to manually add those PID in the list of supported devices. This patch implements the pen support only. The finger part will come in a later patch. To be properly notified of an .event() and a .report(), we need to force hid-core to go through the HID parsing. By default, wacom.ko binds only hidraw, so the hid parsing is not done by hid-core. When a true HID device is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will force hid-core to parse the incoming reports. (Note that this can be easily backported by directly setting the .claimed flag to HID_CLAIMED_DRIVER even if hid-core does not support HID_CONNECT_DRIVER) Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Jason Gerecke <killertofu@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2014-10-01net/mlx4_core: New init and exit flow for mlx4_coreMajd Dibbiny1-0/+1
In the new flow, we separate the pci initialization and teardown from the initialization and teardown of the other resources. __mlx4_init_one handles the pci resources initialization. It then calls mlx4_load_one to initialize the remainder of the resources. When removing a device, mlx4_remove_one is invoked. However, now mlx4_remove_one calls mlx4_unload_one to free all the resources except the pci resources. When mlx4_unload_one returns, mlx4_remove_one then frees the pci resources. The above separation will allow us to implement 'reset flow' in the future. It will also enable more EQs for VFs and is a pre-step to the modern API to enable/disable SRIOV. Also added nvfs; an integer array of size MLX4_MAX_PORTS + 1; to the mlx4_dev struct. This new field is used to avoid parsing the num_vfs module parameter each time the mlx4_restart_one is called.

This driver is used by the bcm53xx ARM SoC code. Now it is possible to give the address of the chipcommon core in device tree and bcma will search for all the other cores.
