Emil Tantilov b08e1ed9cf ixgbe: zero out mailbox buffer on init
This patch initializes the msgbuf array to 0 in order to avoid using random
numbers from the memory as MAC address for the VF.

  ixgbe: ethtool ixgbe_diag_test cleanup

Specifically forcing the laser before the link check can lead to
inconsistent results because it does not guarantee that the link will be
negotiated correctly. Such is the case when dual speed SFP+ module is
connected to a gigabit link partner.

Don Skidmore bd8a1b1290 ixgbe: fix incorrect limit value in ring transverse
We were transversing the tx_ring with IXGBE_NUM_RX_QUEUES.  Now this define
happens to have the correct value but this is misleading and a change later
could easily make this no longer true.  I updated it to netdev->num_tx_queues
like we use in ixgbe_get_strings().

Dan Carpenter 80b17be70b qlcnic: underflow in qlcnic_validate_max_tx_rings()
This function checks the upper bound but it doesn't check for negative
numbers:

	if (txq > QLCNIC_MAX_TX_RINGS) {

I've solved this by making "txq" a u32 type.  I chose that because
->tx_count in the ethtool_channels struct is a __u32.

This bug was added in aa4a1f7df7 ('qlcnic: Enable Tx queue changes using

David S. Miller 823a19e0cf Merge branch 'xen-netback'
Wei Liu says:

====================
xen-netback: switch to NAPI + kthread 1:1 model

This series implements NAPI + kthread 1:1 model for Xen netback.

This model
 - provides better scheduling fairness among vifs
 - is prerequisite for implementing multiqueue for Xen network driver

The second patch has the real meat:
 - make use of NAPI to mitigate interrupt
 - kthreads are not bound to CPUs any more, so that we can take
   advantage of backend scheduler and trust it to do the right thing

Benchmark is done on a Dell T3400 workstation with 4 cores, running 4
DomUs. Netserver runs in Dom0. DomUs do netperf to Dom0 with
following command: /root/netperf -H Dom0 -fm -l120

IRQs are distributed to 4 cores by hand in the new model, while in the
old model vifs are automatically distributed to 4 kthreads.

* New model
%Cpu0  :  0.5 us, 20.3 sy,  0.0 ni, 28.9 id,  0.0 wa,  0.0 hi, 24.4 si, 25.9 st
%Cpu1  :  0.5 us, 17.8 sy,  0.0 ni, 28.8 id,  0.0 wa,  0.0 hi, 27.7 si, 25.1 st

%Cpu3  :  0.0 us, 20.1 sy,  0.0 ni, 30.4 id,  0.0 wa,  0.0 hi, 22.7 si, 26.8 st
Throughputs: 2027.89 2025.95 2018.57 2016.23 aggregated: 8088.64

* Old model
%Cpu0  :  0.5 us, 68.8 sy,  0.0 ni, 16.1 id,  0.5 wa,  0.0 hi,  2.8 si, 11.5 st
%Cpu1  :  0.4 us, 45.1 sy,  0.0 ni, 31.1 id,  0.4 wa,  0.0 hi,  2.1 si, 20.9 st
%Cpu2  :  0.9 us, 44.8 sy,  0.0 ni, 30.9 id,  0.0 wa,  0.0 hi,  1.3 si, 22.2 st
%Cpu3  :  0.8 us, 46.4 sy,  0.0 ni, 28.3 id,  1.3 wa,  0.0 hi,  2.1 si, 21.1 st
Throughputs: 1899.14 2280.43 1963.33 1893.47 aggregated: 8036.37

We can see that the impact is mainly on CPU usage. The new model moves
processing from kthread to NAPI (software interrupt).

This patch implements 1:1 model netback. NAPI and kthread are utilized
to do the weight-lifting job:

- NAPI is used for guest side TX (host side RX)
- kthread is used for guest side RX (host side TX)

Xenvif and xen_netbk are made into one structure to reduce code size.

This model provides better scheduling fairness among vifs. It is also
prerequisite for implementing multiqueue for Xen netback.

Wei Liu 43e9d19432 xen-netback: remove page tracking facility
The data flow from DomU to DomU on the same host in current copying
scheme with tracking facility:

       copy
DomU --------> Dom0          DomU
 |                            ^
 |____________________________|
             copy

The page in Dom0 is a page with valid MFN. So we can always copy from
page Dom0, thus removing the need for a tracking facility.

       copy           copy
DomU --------> Dom0 -------> DomU

Simple iperf test shows no performance regression (obviously we copy
twice either way):

  W/  tracking: ~5.3Gb/s
  W/o tracking: ~5.4Gb/s

The skb priority field may help the wireless driver to choose the right

This patch adds support for IPv4/IPv6 DS fields and VLAN PCP. Note that
only VLAN PCP is used if a VLAN header is present. Also initially set
TC_PRIO_CONTROL only for self-generated packets, and keep the priority
set by higher layers.

====================
A number of significant new features and optimizations for net-next/3.12.
Highlights are:
 * "Megaflows", an optimization that allows userspace to specify which
   flow fields were used to compute the results of the flow lookup.
   This allows for a major reduction in flow setups (the major
   performance bottleneck in Open vSwitch) without reducing flexibility.
 * Converting netlink dump operations to use RCU, allowing for
   additional parallelism in userspace.
 * Matching and modifying SCTP protocol fields.

Patrick McHardy 48b1de4c11 netfilter: add SYNPROXY core/target
Add a SYNPROXY for netfilter. The code is split into two parts, the synproxy
core with common functions and an address family specific target.

The SYNPROXY receives the connection request from the client, responds with
a SYN/ACK containing a SYN cookie and announcing a zero window and checks
whether the final ACK from the client contains a valid cookie.

It then establishes a connection to the original destination and, if
successful, sends a window update to the client with the window size
announced by the server.

Support for timestamps, SACK, window scaling and MSS options can be
statically configured as target parameters if the features of the server
are known. If timestamps are used, the timestamp value sent back to
the client in the SYN/ACK will be different from the real timestamp of
the server. In order to now break PAWS, the timestamps are translated in
the direction server->client.

As reported by Casper Gripenberg, in a bridged setup, using ip[6]t_REJECT
with the tcp-reset option sends out reset packets with the src MAC address
of the local bridge interface, instead of the MAC address of the intended
destination.  This causes some routers/firewalls to drop the reset packet
as it appears to be spoofed.  Fix this by bypassing ip[6]_local_out and
setting the MAC of the sender in the tcp reset packet.

This closes netfilter bugzilla #531.

Daniel Borkmann b1dcdc68b1 net: tcp_probe: allow more advanced ingress filtering by mark
Currently, the tcp_probe snooper can either filter packets by a given
port (handed to the module via module parameter e.g. port=80) or lets
all TCP traffic pass (port=0, default). When a port is specified, the
port number is tested against the sk's source/destination port. Thus,
if one of them matches, the information will be further processed for
the log.

As this is quite limited, allow for more advanced filtering possibilities
which can facilitate debugging/analysis with the help of the tcp_probe
snooper. Therefore, similarly as added to BPF machine in commit 7e75f93e
("pkt_sched: ingress socket filter by mark"), add the possibility to
use skb->mark as a filter.

If the mark is not being used otherwise, this allows ingress filtering
by flow (e.g. in order to track updates from only a single flow, or a
subset of all flows for a given port) and other things such as dynamic
logging and reconfiguration without removing/re-inserting the tcp_probe
module, etc. Simple example:

  insmod net/ipv4/tcp_probe.ko fwmark=8888 full=1
  ...
  iptables -A INPUT -i eth4 -t mangle -p tcp --dport 22 \
           --sport 60952 -j MARK --set-mark 8888
  [... sampling interval ...]
  iptables -D INPUT -i eth4 -t mangle -p tcp --dport 22 \
           --sport 60952 -j MARK --set-mark 8888

The current option to filter by a given port is still being preserved. A
similar approach could be done for the sctp_probe module as a follow-up.

Joe Stringer a175a72330 openvswitch: Add SCTP support
This patch adds support for rewriting SCTP src,dst ports similar to the
functionality already available for TCP/UDP.

Rewriting SCTP ports is expensive due to double-recalculation of the
SCTP checksums; this is performed to ensure that packets traversing OVS
with invalid checksums will continue to the destination with any
checksum corruption intact.

Boris BREZILLON 148cbb53ac net/cadence/macb: add support for dt phy definition
The macb driver only handle PHY description through platform_data
(macb_platform_data).
Thus, when using dt you cannot define phy properties like phy address or
phy irq pin.

This patch makes use of the of_mdiobus_register to add support for
phy device definition using dt.
A fallback to the autoscan procedure is added in case there is no phy
devices defined in dt.
