Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...
2013-07-02Merge branch 'for-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wqLinus Torvalds1-4/+5
Pull workqueue changes from Tejun Heo: "Surprisingly, Lai and I didn't break too many things implementing custom pools and stuff last time around and there aren't any follow-up changes necessary at this point. The only change in this pull request is Viresh's patches to make some per-cpu workqueues to behave as unbound workqueues dependent on a boot param whose default can be configured via a config option. This leads to higher processing overhead / lower bandwidth as more work items are bounced across CPUs; however, it can lead to noticeable powersave in certain configurations - ~10% w/ idlish constant workload on a big.LITTLE configuration according to Viresh. This is because per-cpu workqueues interfere with how the scheduler perceives whether or not each CPU is idle by forcing pinned tasks on them, which makes the scheduler's power-aware scheduling decisions less effective. Its effectiveness is likely less pronounced on homogenous configurations and this type of optimization can probably be made automatic; however, the changes are pretty minimal and the affected workqueues are clearly marked, so it's an easy gain for some configurations for the time being with pretty unintrusive changes." * 'for-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: fbcon: queue work on power efficient wq block: queue work on power efficient wq PHYLIB: queue work on system_power_efficient_wq workqueue: Add system wide power_efficient workqueues workqueues: Introduce new flag WQ_POWER_EFFICIENT for power oriented workqueues

2013-05-27phy: allow drivers to flag a PHY device as internalFlorian Fainelli2-1/+5
libphy currently always reports a PHY as an external transceiver from the ethtool output. This is inaccurate, because some drivers should be able to tell that a PHY device is an internal transceiver of an Ethernet MAC. Add a new flag (PHY_IS_INTERNAL) which can be set by PHY drivers just like other flags, and a corresponding helper: phy_is_internal() which can be used by networking drivers to query if a given PHY device is internal.

2013-05-20phy: add phy_mac_interrupt() to use with PHY_IGNORE_INTERRUPTFlorian Fainelli2-5/+10
There is currently no way for an Ethernet MAC driver servicing PHY link interrupts to notify this to the PHY state machine without defining its own state machine. Since most drivers are not so special, introduce a helper: phy_mac_interrupt() which can be called from a link up/down interrupt routine to update the PHY state machine. To avoid code duplication some refactoring has been done to expose the workqueue and its corresponding callback internally.

2013-05-20phy: fix the use of PHY_IGNORE_INTERRUPTFlorian Fainelli2-6/+10
When a PHY device is registered with the special IRQ value PHY_IGNORE_INTERRUPT (-2) it will not properly be handled by the PHY library: - it continues to poll its register, while we do not want this because such PHY link events or register changes are serviced by an Ethernet MAC - it will still try to configure PHY interrupts at the PHY level, such interrupts do not exist at the PHY but at the MAC level - the state machine only handles PHY_POLL, but should also handle PHY_IGNORE_INTERRUPT similarly This patch updates the PHY state machine and initialization paths to account for the specific PHY_IGNORE_INTERRUPT. Based on an earlier patch by Thomas Petazzoni, and reworked to add the missing bits. Add a helper phy_interrupt_is_valid() which specifically tests for a PHY interrupt not to be PHY_POLL or PHY_IGNORE_INTERRUPT and use it throughout the code.

Phylib uses workqueues for multiple purposes. There is no real dependency of scheduling these on the cpu which scheduled them. On a idle system, it is observed that and idle cpu wakes up many times just to service this work. It would be better if we can schedule it on a cpu which the scheduler believes to be the most appropriate one. This patch replaces system_wq with system_power_efficient_wq for PHYLIB. Cc: David S.

GENERIC_GPIO is now equivalent to GPIOLIB and features that depended on GENERIC_GPIO can now depend on GPIOLIB to allow removal of this option.

In case of fixed speed set up for a NIC (e.g. ethtool -s eth0 autoneg off speed 100 duplex full) with an ethernet cable plugged off, the mentioned algorithm slows down a NIC speed, so further cable hook-up leads to nonoperable link state.

2013-03-12mv643xx_eth with 88E1318S: support Wake on LANMichael Stapelberg1-0/+127
This has been tested on a qnap TS-119P II. Note that enabling WOL with "ethtool -s eth0 wol g" is not enough; you also need to tell the PIC microcontroller inside the qnap that WOL should be enabled by sending 0xF2 with qcontrol(1) and you have to disable EUP ("Energy-using Products", a European power-saving thing) by sending 0xF4.

2013-03-12phy/micrel: move flag handling to function for common useHector Palacios1-9/+18
The flag MICREL_PHY_50MHZ_CLK is not of exclusive use of KSZ8051 model. At least KSZ8021 and KSZ8031 models also use it. This patch moves the handling of this and future flags to a separate function so that the different PHY models can call it on their init function, if needed.
