This patch enables 'can_dma_sg' flag for ax88179_178a device if the attached host controller supports building packet from discontinuous buffers(DMA SG is possible), so TSO can be enabled and skb fragment buffers can be passed to usb stack via urb->sg directly.

2013-08-03ax88179_178a: avoid copy of tx tcp packetsEric Dumazet
ax88179_tx_fixup() has quite complex code trying to push 8 bytes of control data (len/mss), but fails to do it properly for TCP packets, incurring an extra copy and point of memory allocation failure. Lets use the simple and approved way. dev->needed_headroom being 8, all frames should have 8 bytes of headroom, so the extra copy should be unlikely anyway.

2013-07-27USBNET: centralize computing of max rx/tx qlenMing Lei
This patch centralizes computing of max rx/tx qlen, because: - RX_QLEN()/TX_QLEN() is called in hot path - computing depends on device's usb speed, now we have ls/fs, hs, ss, so more checks need to be involved - in fact, max rx/tx qlen should not only depend on device USB speed, but also depend on ethernet link speed, so we need to consider that in future. - if SG support is done, max tx qlen may need change too Generally, hard_mtu and rx_urb_size are changed in bind(), reset() and link_reset() callback, and change mtu network operation, this patches introduces the API of usbnet_update_max_qlen(), and calls it in above path.

2013-07-26usbnet: do not pretend to support SG/TSOEric Dumazet
usbnet doesn't support yet SG, so drivers should not advertise SG or TSO capabilities, as they allow TCP stack to build large TSO packets that need to be linearized and might use order-5 pages. This adds an extra copy overhead and possible allocation failures. Current code ignore skb_linearize() return code so crashes are even possible. Best is to not pretend SG/TSO is supported, and add this again when/if usbnet really supports SG for devices who could get a performance gain.

The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>
2013-06-11qmi_wwan/cdc_ether: let qmi_wwan handle the Huawei E1820Bjørn Mork
Another QMI speaking Qualcomm based device, which should be driven by qmi_wwan, while cdc_ether should ignore it. Like on other Huawei devices, the wwan function can appear either as a single vendor specific interface or as a CDC ECM class function using separate control and data interfaces. The ECM control interface protocol is 0xff, likely in an attempt to indicate that vendor specific management is required. In addition to the near standard CDC class, Huawei also add vendor specific AT management commands to their firmwares. This is probably an attempt to support non-Windows systems using standard class drivers. Unfortunately, this part of the firmware is often buggy. Linux is much better off using whatever native vendor specific management protocol the device offers, and Windows uses, whenever possible. This means QMI in the case of Qualcomm based devices. The E1820 has been verified to work fine with QMI. Matching on interface number is necessary to distiguish the wwan function from serial functions in the single interface mode, as both function types will have class/subclass/function set to ff/ff/ff. The control interface number does not change in CDC ECM mode, so the interface number matching rule is sufficient to handle both modes. The cdc_ether blacklist entry is only relevant in CDC ECM mode, but using a similar interface number based rule helps document this as a transfer from one driver to another. Other Huawei 02/06/ff devices are left with the cdc_ether driver because we do not know whether they are based on Qualcomm chips. The Huawei specific AT command management is known to be somewhat hardware independent, and their usage of these class codes may also be independent of the modem hardware.

2013-05-08sierra_net: keep status interrupt URB activeDan Williams
The driver and firmware sync up through SYNC messages, and the firmware's affirmative reply to these SYNC messages appears to be the "Reset" indication received via the status interrupt endpoint. Thus the driver needs the status interrupt endpoint always active so that the Reset indication can be received even if the netdev is closed, which is the case right after device insertion. If the Reset indication is not received by the driver, it continues sending SYNC messages to the firmware, which crashes about 10 seconds later and the device stops responding.

2013-05-08usbnet: allow status interrupt URB to always be activeDan Williams
Some drivers (sierra_net) need the status interrupt URB active even when the device is closed, because they receive custom indications from firmware. Add functions to refcount the status interrupt URB submit/kill operation so that sub-drivers and the generic driver don't fight over whether the status interrupt URB is active or not. A sub-driver can call usbnet_status_start() at any time, but the URB is only submitted the first time the function is called. Likewise, when the sub-driver is done with the URB, it calls usbnet_status_stop() but the URB is only killed when all users have stopped it. The URB is still killed and re-submitted for suspend/resume, as before, with the same refcount it had at suspend.

There is bug in the receive path of the asix driver at the time a packet is received larger than MTU size and DF bit set: BUG: unable to handle kernel paging request at 0000004000000001 IP: [<ffffffff8126f65b>] skb_release_head_state+0x2d/0xd2 ... Call Trace: <IRQ> [<ffffffff8126f86d>] ? skb_release_all+0x9/0x1e [<ffffffff8126f8ad>] ? __kfree_skb+0x9/0x6f [<ffffffffa00b4200>] ? asix_rx_fixup_internal+0xff/0x1ae [asix] [<ffffffffa00fb3dc>] ? usbnet_bh+0x4f/0x226 [usbnet] ... It is easily reproducable by setting an MTU of 512 e. g. and sending something like ping -s 1472 -c 1 -M do $SELF from another box. And this is because the rx->ax_skb is freed on error, but rx->ax_skb is not reset, and the size is not reset to zero in this case. And since the skb is added again to the usbnet->done skb queue it is accessing already freed memory, resulting in the BUG when freeing a 2nd time. I therefore think the value 0x0000004000000001 show in the trace is more or less random data. Signed-off-by: Holger Eitzenberger <holger@eitzenberger.org> Signed-off-by: David S.

Pull networking updates from David Miller: "Highlights (1721 non-merge commits, this has to be a record of some sort): 1) Add 'random' mode to team driver, from Jiri Pirko and Eric Dumazet. 2) Make it so that any driver that supports configuration of multiple MAC addresses can provide the forwarding database add and del calls by providing a default implementation and hooking that up if the driver doesn't have an explicit set of handlers. From Vlad Yasevich. 3) Support GSO segmentation over tunnels and other encapsulating devices such as VXLAN, from Pravin B Shelar. 4) Support L2 GRE tunnels in the flow dissector, from Michael Dalton. 5) Implement Tail Loss Probe (TLP) detection in TCP, from Nandita Dukkipati. 6) In the PHY layer, allow supporting wake-on-lan in situations where the PHY registers have to be written for it to be configured. Use it to support wake-on-lan in mv643xx_eth. From Michael Stapelberg. 7) Significantly improve firewire IPV6 support, from YOSHIFUJI Hideaki. 8) Allow multiple packets to be sent in a single transmission using network coding in batman-adv, from Martin Hundebøll. 9) Add support for T5 cxgb4 chips, from Santosh Rastapur. 10) Generalize the VXLAN forwarding tables so that there is more flexibility in configurating various aspects of the endpoints. From David Stevens. 11) Support RSS and TSO in hardware over GRE tunnels in bxn2x driver, from Dmitry Kravkov. 12) Zero copy support in nfnelink_queue, from Eric Dumazet and Pablo Neira Ayuso. 13) Start adding networking selftests. 14) In situations of overload on the same AF_PACKET fanout socket, or per-cpu packet receive queue, minimize drop by distributing the load to other cpus/fanouts. From Willem de Bruijn and Eric Dumazet. 15) Add support for new payload offset BPF instruction, from Daniel Borkmann. 16) Convert several drivers over to mdoule_platform_driver(), from Sachin Kamat. 17) Provide a minimal BPF JIT image disassembler userspace tool, from Daniel Borkmann. 18) Rewrite F-RTO implementation in TCP to match the final specification of it in RFC4138 and RFC5682. From Yuchung Cheng. 19) Provide netlink socket diag of netlink sockets ("Yo dawg, I hear you like netlink, so I implemented netlink dumping of netlink sockets.") From Andrey Vagin. 20) Remove ugly passing of rtnetlink attributes into rtnl_doit functions, from Thomas Graf. 21) Allow userspace to be able to see if a configuration change occurs in the middle of an address or device list dump, from Nicolas Dichtel. 22) Support RFC3168 ECN protection for ipv6 fragments, from Hannes Frederic Sowa. 23) Increase accuracy of packet length used by packet scheduler, from Jason Wang. 24) Beginning set of changes to make ipv4/ipv6 fragment handling more scalable and less susceptible to overload and locking contention, from Jesper Dangaard Brouer. 25) Get rid of using non-type-safe NLMSG_* macros and use nlmsg_*() instead. From Hong Zhiguo. 26) Optimize route usage in IPVS by avoiding reference counting where possible, from Julian Anastasov. 27) Convert IPVS schedulers to RCU, also from Julian Anastasov. 28) Support cpu fanouts in xt_NFQUEUE netfilter target, from Holger Eitzenberger. 29) Network namespace support for nf_log, ebt_log, xt_LOG, ipt_ULOG, nfnetlink_log, and nfnetlink_queue. From Gao feng. 30) Implement RFC3168 ECN protection, from Hannes Frederic Sowa. 31) Support several new r8169 chips, from Hayes Wang. 32) Support tokenized interface identifiers in ipv6, from Daniel Borkmann. 33) Use usbnet_link_change() helper in USB net driver, from Ming Lei. 34) Add 802.1ad vlan offload support, from Patrick McHardy. 35) Support mmap() based netlink communication, also from Patrick McHardy. 36) Support HW timestamping in mlx4 driver, from Amir Vadai. 37) Rationalize AF_PACKET packet timestamping when transmitting, from Willem de Bruijn and Daniel Borkmann. 38) Bring parity to what's provided by /proc/net/packet socket dumping and the info provided by netlink socket dumping of AF_PACKET sockets. From Nicolas Dichtel. 39) Fix peeking beyond zero sized SKBs in AF_UNIX, from Benjamin Poirier" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1722 commits) filter: fix va_list build error af_unix: fix a fatal race with bit fields bnx2x: Prevent memory leak when cnic is absent bnx2x: correct reading of speed capabilities net: sctp: attribute printl with __printf for gcc fmt checks netlink: kconfig: move mmap i/o into netlink kconfig netpoll: convert mutex into a semaphore netlink: Fix skb ref counting. net_sched: act_ipt forward compat with xtables mlx4_en: fix a build error on 32bit arches Revert "bnx2x: allow nvram test to run when device is down" bridge: avoid OOPS if root port not found drivers: net: cpsw: fix kernel warn on cpsw irq enable sh_eth: use random MAC address if no valid one supplied 3c509.c: call SET_NETDEV_DEV for all device types (ISA/ISAPnP/EISA) tg3: fix to append hardware time stamping flags unix/stream: fix peeking with an offset larger than data in queue unix/dgram: fix peeking with an offset larger than data in queue unix/dgram: peek beyond 0-sized skbs openvswitch: Remove unneeded ovs_netdev_get_ifindex() ...
