Commit ce93718f ("net: Don't keep

original skb after software GSO even for dodgy gso skbs. This breaks
the stream throughput from untrusted sources, since only header
checking was done during software GSO instead of a true
segmentation. This patch fixes this by freeing the original gso skb
only when it was really segmented by software.

Intel Wired LAN Driver Updates 2014-09-18

This series contains updates to ixgbe and ixgbevf.

Ethan Zhao cleans up ixgbe and ixgbevf by removing bd_number from the
adapter struct because it is not longer useful.

Mark fixes ixgbe where if a hardware transmit timestamp is requested,
an uninitialized workqueue entry may be scheduled.  Added a check for
a PTP clock to avoid that.

Jacob provides a number of cleanups for ixgbe.  Since we may call
ixgbe_acquire_msix_vectors() prior to registering our netdevice, we
should not use the netdevice specific printk and use e_dev_warn()
instead.  Similar to how ixgbevf handles acquiring MSI-X vectors, we
can return an error code instead of relying on the flag being set.
This makes it more clear that we have failed to setup MSI-X mode and
will make it easier to consolidate MSI-X related code into a single
function.  In the case of disabling DCB, it is not an error since we
still can function, we just have to let the user know.  So use
e_dev_warn() instead of e_err().  Added warnings for other features
that are disabled when we are without MSI-X support.  Cleanup flags
that are no longer used or needed.

mlx4: CQE/EQE stride support

This series from Ido Shamay is intended for archs having
cache line larger then 64 bytes.

Since our CQE/EQEs are generally 64B in those systems, HW will write
twice to the same cache line consecutively, causing pipe locks due to
he hazard prevention mechanism. For elements in a cyclic buffer, writes
are consecutive, so entries smaller than a cache line should be
avoided, especially if they are written at a high rate.

Reduce consecutive writes to same cache line in CQs/EQs, by allowing the
driver to increase the distance between entries so that each will reside
in a different cache line.

This function derives the base address of the CQE from the CQE size,
and calculates the real CQE context segment in it from the factor
(this is like before). Before this change the code used the factor to
calculate the base address of the CQE as well.

The factor indicates in which segment of the cqe stride the cqe information
is located. For 32-byte strides, the segment is 0, and for 64 byte strides,
the segment is 1 (bytes 32..63). Using the factor was ok as long as we had
only 32 and 64 byte strides. However, with larger strides, the factor is zero,
and so cannot be used to calculate the base of the CQE.

The helper uses the same method of CQE buffer pulling made by all other
components that reads the CQE buffer (mlx4_ib driver and libmlx4).

Reduce consecutive writes to same cache line in CQs/EQs, by allowing the

were two types of CQE/EQE:

1. 32B stride and context in the [0-31] segment
2. 64B stride and context in the [32-63] segment

This feature introduces two additional types:

3. 128B stride and context in the [0-31] segment (128B cache line)
4. 256B stride and context in the [0-31] segment (256B cache line)

Modify the mlx4_core driver to query the device for the CQE/EQE cache
line stride capability and to enable that capability when the host
cache line size is larger than 64 bytes (supported cache lines are
128B and 256B).

The mlx4 IB driver and libmlx4 need not be aware of this change. The PF
context behaviour is changed to require this change in VF drivers
running on such archs.

net: foo-over-udp (fou)

This patch series implements foo-over-udp. The idea is that we can
encapsulate different IP protocols in UDP packets. The rationale for
this is that networking devices such as NICs and switches are usually
implemented with UDP (and TCP) specific mechanims for processing. For
instance, many switches and routers will implement a 5-tuple hash
for UDP packets to perform Equal Cost Multipath Routing (ECMP) or
RSS (on NICs). Many NICs also only provide rudimentary checksum
offload (basic TCP and UDP packet), with foo-over-udp we may be
able to leverage these NICs to offload checksums of tunneled packets
(using checksum unnecessary conversion and eventually remote checksum
offload)

An example encapsulation of IPIP over FOU is diagrammed below. As
illustrated, the packet overhead for FOU is the 8 byte UDP header.

+------------------+
|    IPv4 hdr      |
+------------------+
|     UDP hdr      |
+------------------+
|    IPv4 hdr      |
+------------------+
|     TCP hdr      |
+------------------+
|   TCP payload    |
+------------------+

Conceptually, FOU should be able to encapsulate any IP protocol.
The FOU header (UDP hdr.) is essentially an inserted header between the
IP header and transport, so in the case of TCP or UDP encapsulation
the pseudo header would be based on the outer IP header and its length
field must not include the UDP header.

* Receive

In this patch set the RX path for FOU is implemented in a new fou
module. To enable FOU for a particular protocol, a UDP-FOU socket is
opened to the port to receive FOU packets. The socket is mapped to the
IP protocol for the packets. The XFRM mechanism used to receive
encapsulated packets (udp_encap_rcv) for the port. Upon reception, the
UDP is removed and packet is reinjected in the stack for the
corresponding protocol associated with the socket (return -protocol
from udp_encap_rcv function).

GRO is provided with the appropriate fou_gro_receive and
fou_gro_complete. These routines need to know the encapsulation
protocol so we save that in udp_offloads structure with the port
and pass it in the napi_gro_cb structure.

* TX

This patch series implements FOU transmit encapsulation for IPIP, GRE, and
SIT. This done by some common infrastructure in ip_tunnel including an
ip_tunnel_encap to perform FOU encapsulation and common configuration
to enable FOU on IP tunnels. FOU is configured on existing tunnels and
does not create any new interfaces. The transmit and receive paths are
independent, so use of FOU may be assymetric between tunnel endpoints.

* Configuration

The fou module using netlink to configure FOU receive ports. The ip
command can be augmented with a fou subcommand to support this. e.g. to
configure FOU for IPIP on port 5555:

  ip fou add port 5555 ipproto 4

GRE, IPIP, and SIT have been modified with netlink commands to
configure use of FOU on transmit. The "ip link" command will be
augmented with an encap subcommand (for supporting various forms of
secondary encapsulation). For instance, to configure an ipip tunnel
with FOU on port 5555:

  ip link add name tun1 type ipip \
    remote 192.168.1.1 local 192.168.1.2 ttl 225 \
    encap fou encap-sport auto encap-dport 5555

* Notes
  - This patch set does not implement GSO for FOU. The UDP encapsulation
    code assumes TEB, so that will need to be reimplemented.
  - When a packet is received through FOU, the UDP header is not
    actually removed for the skbuf, pointers to transport header
    and length in the IP header are updated (like in ESP/UDP RX). A
    side effect is the IP header will now appear to have an incorrect
    checksum by an external observer (e.g. tcpdump), it will be off
    by sizeof UDP header. If necessary we could adjust the checksum
    to compensate.
  - Performance results are below. My expectation is that FOU should
    entail little overhead (clearly there is some work to do :-) ).
    Optimizing UDP socket lookup for encapsulation ports should help
    significantly.
  - I really don't expect/want devices to have special support for any
    of this. Generic checksum offload mechanisms (NETIF_HW_CSUM
    and use of CHECKSUM_COMPLETE) should be sufficient. RSS and flow
    steering is provided by commonly implemented UDP hashing. GRO/GSO
    seem fairly comparable with LRO/TSO already.

* Performance

Ran netperf TCP_RR and TCP_STREAM tests across various configurations.
This was performed on bnx2x and I disabled TSO/GSO on sender to get
fair comparison for FOU versus non-FOU. CPU utilization is reported
for receive in TCP_STREAM.

This patch provides a receive path for foo-over-udp. This allows
direct encapsulation of IP protocols over UDP. The bound destination
port is used to map to an IP protocol, and the XFRM framework
(udp_encap_rcv) is used to receive encapsulated packets. Upon
reception, the encapsulation header is logically removed (pointer
to transport header is advanced) and the packet is reinjected into
the receive path with the IP protocol indicated by the mapping.

Netlink is used to configure FOU ports. The configuration information
includes the port number to bind to and the IP protocol corresponding
to that port.

This should support GRE/UDP
(http://tools.ietf.org/html/draft-yong-tsvwg-gre-in-udp-encap-02),
as will as the other IP tunneling protocols (IPIP, SIT).

(They instead use the standard qdisc lock)

We can use __skb_queue_head_init() instead of skb_queue_head_init()
to be consistent.

bnx2x: Support new Multi-function modes

This patch series adds support for 2 new Multi-function modes -
Unified Fabric Port [UFP] as well as nic partitioning 1.5 [NPAR1.5].

With the addition of the new multi-function modes, the series also
revises some of the storage-related multi-function macros.

[Do notice this series has several small issues with checkpatch]

When using new Multi-function modes it's possible that due to incompatible
configuration management FW will fallback into an existing mode.

Notice that at the moment this fallback is exactly the same as the already
existing switch-independent multi-function mode, but we still use existing
infrastructure to hold this information [in case some small differences will
arise in the future].

Add support for a new multi-function mode based on the Unified Fabric Port
system specifications.
Support includes configuration of:
  1. Outer vlan tags.
  2. Bandwidth settings.
  3. Virtual link enable/disable.
