Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next 

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 0a4db187a9 ("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."

Marvell Orion/Discovery ethernet controller
=============================================
The Marvell Discovery ethernet controller can be found on Marvell Orion SoCs
(Kirkwood, Dove, Orion5x, and Discovery Innovation) and as part of Marvell
Discovery system controller chips (mv64[345]60).
The Discovery ethernet controller is described with two levels of nodes. The
first level describes the ethernet controller itself and the second level
describes up to 3 ethernet port nodes within that controller. The reason for
the multiple levels is that the port registers are interleaved within a single
set of controller registers. Each port node describes port-specific properties.
Note: The above separation is only true for Discovery system controllers.
For Orion SoCs we stick to the separation, although there each controller has
only one port associated. Multiple ports are implemented as multiple single-port
controllers. As Kirkwood has some issues with proper initialization after reset,
an extra compatible string is added for it.
* Ethernet controller node
Required controller properties:
- #address-cells: shall be 1.
- #size-cells: shall be 0.
- compatible: shall be one of "marvell,orion-eth", "marvell,kirkwood-eth".
- reg: address and length of the controller registers.
Optional controller properties:
- clocks: phandle reference to the controller clock.
- marvell,tx-checksum-limit: max tx packet size for hardware checksum.
* Ethernet port node
Required port properties:
- device_type: shall be "network".
- compatible: shall be one of "marvell,orion-eth-port",
"marvell,kirkwood-eth-port".
- reg: port number relative to ethernet controller, shall be 0, 1, or 2.
- interrupts: port interrupt.
- local-mac-address: 6 bytes MAC address.
Optional port properties:
- marvell,tx-queue-size: size of the transmit ring buffer.
- marvell,tx-sram-addr: address of transmit descriptor buffer located in SRAM.
- marvell,tx-sram-size: size of transmit descriptor buffer located in SRAM.
- marvell,rx-queue-size: size of the receive ring buffer.
- marvell,rx-sram-addr: address of receive descriptor buffer located in SRAM.
- marvell,rx-sram-size: size of receive descriptor buffer located in SRAM.
and
- phy-handle: phandle reference to ethernet PHY.
or
- speed: port speed if no PHY connected.

1.2 Install ifenslave Control Utility
1.2 Bonding Control Utility
-------------------------------------
The ifenslave user level control program is included in the
kernel source tree, in the file Documentation/networking/ifenslave.c.
It is generally recommended that you use the ifenslave that
corresponds to the kernel that you are using (either from the same
source tree or supplied with the distro), however, ifenslave
executables from older kernels should function (but features newer
than the ifenslave release are not supported). Running an ifenslave
that is newer than the kernel is not supported, and may or may not
work.
To install ifenslave, do the following:
# gcc -Wall -O -I/usr/src/linux/include ifenslave.c -o ifenslave
# cp ifenslave /sbin/ifenslave
If your kernel source is not in "/usr/src/linux," then replace
"/usr/src/linux/include" in the above with the location of your kernel
source include directory.
You may wish to back up any existing /sbin/ifenslave, or, for
testing or informal use, tag the ifenslave to the kernel version
(e.g., name the ifenslave executable /sbin/ifenslave-2.6.10).
IMPORTANT NOTE:
If you omit the "-I" or specify an incorrect directory, you
may end up with an ifenslave that is incompatible with the kernel
you're trying to build it for. Some distros (e.g., Red Hat from 7.1
onwards) do not have /usr/include/linux symbolically linked to the
default kernel source include directory.
SECOND IMPORTANT NOTE:
If you plan to configure bonding using sysfs or using the
/etc/network/interfaces file, you do not need to use ifenslave.
It is recommended to configure bonding via iproute2 (netlink)
or sysfs, the old ifenslave control utility is obsolete.

@ -163,6 +163,64 @@ and unnecessary. If there are fewer hardware queues than CPUs, then
RPS might be beneficial if the rps_cpus for each queue are the ones that
share the same memory domain as the interrupting CPU for that queue.
==== RPS Flow Limit
RPS scales kernel receive processing across CPUs without introducing
reordering. The trade-off to sending all packets from the same flow
to the same CPU is CPU load imbalance if flows vary in packet rate.
In the extreme case a single flow dominates traffic. Especially on
common server workloads with many concurrent connections, such
behavior indicates a problem such as a misconfiguration or spoofed
source Denial of Service attack.
Flow Limit is an optional RPS feature that prioritizes small flows
during CPU contention by dropping packets from large flows slightly
ahead of those from small flows. It is active only when an RPS or RFS
destination CPU approaches saturation. Once a CPU's input packet
queue exceeds half the maximum queue length (as set by sysctl
net.core.netdev_max_backlog), the kernel starts a per-flow packet
count over the last 256 packets. If a flow exceeds a set ratio (by
default, half) of these packets when a new packet arrives, then the
new packet is dropped. Packets from other flows are still only
dropped once the input packet queue reaches netdev_max_backlog.
No packets are dropped when the input packet queue length is below
the threshold, so flow limit does not sever connections outright:
even large flows maintain connectivity.
== Interface
Flow limit is compiled in by default (CONFIG_NET_FLOW_LIMIT), but not
turned on. It is implemented for each CPU independently (to avoid lock
and cache contention) and toggled per CPU by setting the relevant bit
in sysctl net.core.flow_limit_cpu_bitmap. It exposes the same CPU
bitmap interface as rps_cpus (see above) when called from procfs:
/proc/sys/net/core/flow_limit_cpu_bitmap
Per-flow rate is calculated by hashing each packet into a hashtable
bucket and incrementing a per-bucket counter. The hash function is
the same that selects a CPU in RPS, but as the number of buckets can
be much larger than the number of CPUs, flow limit has finer-grained
identification of large flows and fewer false positives. The default
table has 4096 buckets. This value can be modified through sysctl
net.core.flow_limit_table_len
The value is only consulted when a new table is allocated. Modifying
it does not update active tables.
== Suggested Configuration
Flow limit is useful on systems with many concurrent connections,
where a single connection taking up 50% of a CPU indicates a problem.
In such environments, enable the feature on all CPUs that handle
network rx interrupts (as set in /proc/irq/N/smp_affinity).
The feature depends on the input packet queue length to exceed
the flow limit threshold (50%) + the flow history length (256).
Setting net.core.netdev_max_backlog to either 1000 or 10000
performed well in experiments.

For printing an IP address without the need to distinguish whether it's
of type AF_INET or AF_INET6, a pointer to a valid 'struct sockaddr',
specified through 'IS' or 'iS', can be passed to this format specifier.
The additional 'p', 'f', and 's' specifiers are used to specify port
(IPv4, IPv6), flowinfo (IPv6) and scope (IPv6). Ports have a ':' prefix,
flowinfo a '/' and scope a '%', each followed by the actual value.
In case of an IPv6 address the compressed IPv6 address as described by
http://tools.ietf.org/html/rfc5952 is being used if the additional
specifier 'c' is given. The IPv6 address is surrounded by '[', ']' in
case of additional specifiers 'p', 'f' or 's' as suggested by
https://tools.ietf.org/html/draft-ietf-6man-text-addr-representation-07
In case of IPv4 addresses, the additional 'h', 'n', 'b', and 'l'
specifiers can be used as well and are ignored in case of an IPv6
address.
