This reverts commit 5a5abb1fa3b05dd ("tun, bpf: fix suspicious RCU usage
in tun_{attach, detach}_filter") and replaces it to use lock_sock around
sk_{attach,detach}_filter. The checks inside filter.c are updated with
lockdep_sock_is_held to check for proper socket locks.
It keeps the code cleaner by ensuring that only one lock governs the
socket filter instead of two independent locks.

1GbE Intel Wired LAN Driver Updates 2016-04-06
This series contains updates to e1000, e1000e, igb and Kconfig.
Alex fixes igb where we were casting the MAC address as __beXX and then
passing it into le32_to_cpu, when we could simply cast as __lexx to
maintain consistency since it is already little endian. Then enabled
bulk free in transmit cleanup for igb.
John Holland enables igb to pickup the MAC address from a device tree
blob when CONFIG_OF has been enabled.
Doron Shikmoni fixes a bug in the output of "ethtool -m ethX" where
the data byte appeared duplicated.
Stefan fixes up e1000 and e1000e ethtool offline tests which were calling
dev_close() which causes IFF_UP to be cleared which removes teh interface
routes and some addresses, so use ndo_stop() instead.
Jiri Benc cleans up some old links in the Kconfig for Intel drivers where
we referred to a URL which is no longer valid. I am so glad Jiri has the
time in his day to spend clicking on and testing all the URL links in the
the kernel.

The Kconfig for Intel NICs references two different URLs for the "Adapter
& Driver ID Guide". Neither of those two links works. The current URL seems
to be
http://www.intel.com/content/www/us/en/support/network-and-i-o/ethernet-products/000005584.html
but given it's apparently constantly changing, there's no point in having it
in the help text.
Just keep a generic pointer to http://support.intel.com. Hopefully, this one
will have a longer live. It still works, at least.
Furthermore, remove a link to "the latest Intel PRO/100 network driver for
Linux", this has no place in the mainline kernel and the latest Linux driver
it offers is from 2006, anyway.

Implement the appropriate DCB ops and allow a user to configure certain
traffic classes as lossless.
The operation configures PFC for both the egress (respecting PFC frames)
and ingress (sending PFC frames) parts of the port.
At egress, when a PFC frame is received for a PFC enabled priority, then
all the priorities mapped to the same TC are stopped.
At ingress, the priority group (PG) buffers to which the enabled PFC
priorities are mapped are configured to be lossless. PFC frames will be
transmitted when the Xoff threshold is crossed.
The user-supplied delay parameter is used to determine the PG's size
according to the following formula:
PG_SIZE = PG_SIZE_LOSSY + delay * CELL_FACTOR + MTU
In the worst case scenario the delay will be made up of packets that
are all of size CELL_SIZE + 1, which means each packet will require
almost twice its true size when buffered in the switch. We therefore
multiply this value by the "cell factor", which is close to 2.
Another MTU is added in case the transmitting host already started
transmitting a maximum length frame when the PFC packet was received.
As with PAUSE enabled ports, when the port's MTU is changed both the
PGs' size and threshold are adjusted accordingly.

When a packet ingress the switch it's placed in its assigned priority
group (PG) buffer in the port's headroom buffer while it goes through
the switch's pipeline. After going through the pipeline - which
determines its egress port(s) and traffic class - it's moved to the
switch's shared buffer awaiting transmission.
However, some packets are not eligible to enter the shared buffer due to
exceeded quotas or insufficient space. Marking their associated PGs as
lossless will cause the packets to accumulate in the PG buffer. Another
reason for packets accumulation are complicated pipelines (e.g.
involving a lot of ACLs).
To prevent packets from being dropped a user can enable PAUSE frames on
the port. This will mark all the active PGs as lossless and set their
size according to the maximum delay, as it's not configured by user.

+----------------+ +
The delay (612 [Cells]) was calculated according to worst-case scenario
involving maximum MTU and 100m cables.
After marking the PGs as lossless the device is configured to respect
incoming PAUSE frames (Rx PAUSE) and generate PAUSE frames (Tx PAUSE)
according to user's settings.
Whenever the port's headroom configuration changes we take into account
the PAUSE configuration, so that we correctly set the PG's type (lossy /
lossless), size and threshold. This can happen when:
a) The port's MTU changes, as it directly affects the PG's size.
b) A PG is created following user configuration, by binding a priority
to it.
Note that the relevant SUPPORTED flags were already mistakenly set by
the driver before this commit.

Before introducing support for DCB ops we should first make sure we
initialize the relevant parts in the device correctly. Specifically, the
egress scheduling.
The device supports a superset of the 802.1Qaz standard with 4 hierarchy
levels that can be linked to each other in multiple ways and with
different transmission selection algorithms (TSA) employed between them.
However, since we only intend to support the 802.1Qaz standard we
flatten the hierarchies and let the user configure via DCB ops the TSA
and max rate shaper at the subgroup hierarchy (see figure below) and the
mapping between switch priority to traffic class. By default, all switch
priorities are mapped to traffic class 0, strict priority is employed
and max shaper is disabled.
Default configuration:
switch priority 0 ... switch priority 7

When packets ingress the switch they are assigned a switch priority and
directed to the corresponding priority group (PG) buffer in the port's
headroom buffer.
Since we now map all switch priorities to priority group 0 (PG0) by
default, there is no need to allocate the other priority groups during
initialization. The only exception is PG9, which is used for control
traffic.
At minimum, the PG should be able to store the currently classified
packet (pipeline latency isn't 0) and also the packets arriving during
the classification time. However, an incoming packet will not be
buffered if there is no available MTU-sized buffer space for storing it.
The buffer needed to accommodate for pipeline latency is variable and
needs to take into account both the current link speed and current
latency of the pipeline, which is time-dependent. Testing showed that
setting the PG's size to twice the current MTU is optimal.
Since PG9 is used strictly for control packets and not subject to flow
control, we are not going to resize it according to user configuration,
so we simply set it according to worst case scenario, which is twice the
maximum MTU.
In any case, later patches in the series will allow a user to direct
lossless flows to other PGs than PG0 and set their size to accommodate
for round-trip propagation delay.
The above change also requires us to resize the PG buffer whenever the
port's MTU is changed.

During transmission, the skb's priority is used to map the skb to a
traffic class, where the idea is to group priorities with similar
characteristics (e.g. lossy, lossless) to the same traffic class. By
default, all priorities are mapped to traffic class 0.
In the device, we model the skb's priority as the switch priority, which
is assigned to a packet according to its PCP value and ingress port
(untagged packets are assigned the port's default switch priority - 0).
At ingress, the packet is directed to a priority group (PG) buffer in
the port's headroom buffer according to the packet's switch priority and
switch priority to buffer mapping.
While it's possible to configure the egress mapping between skb's
priority (switch priority) and traffic class, there is no mechanism to
configure the ingress mapping to a PG.
In order to keep things simple and since grouping certain priorities into
a traffic class at egress also implies they should be grouped the same
at ingress, treat a PG as the ingress counterpart of an egress traffic
class.
Having established the above, during initialization map all the switch
priorities to PG0 in accordance with the Linux defaults for traffic
class mapping.

40GbE Intel Wired LAN Driver Updates 2016-04-05
This series contains updates to i40e and i40evf only.
Colin Ian King cleaned up a redundant NULL check which was found by static
analysis.
Anjali enables geneve receive offload for XL710/X710 devices.
Mitch cleans up unused variable in i40e_vc_get_vf_resources_msg().
Fixed the driver to actually be able to adjust VLAN tagging features
through ethtool, as expected. Fixed a problem where VF resets would
get lost by the PF preventing the VF driver from initializing. Also
put users mind at ease by lowering some message levels since many of
these conditions can happen any time VFs are enabled or disabled and
are not really indicative a fatal problems, unless they happen
continuously.
Shannon disables the link polling to lessen the admin queue traffic
especially since the link event mask usage has been fixed recently.
Alex Duyck fixes the i40e and i40evf drivers to correctly update
checksums for frames up to 16776960 in length which should be more than
large enough for all possible TSO frames in the near future.

Implement VXLAN-GPE. Only COLLECT_METADATA is supported for now (it is
possible to support static configuration, too, if there is demand for it).
The GPE header parsing has to be moved before iptunnel_pull_header, as we
need to know the protocol.
v2: Removed what was called "L2 mode" in v1 of the patchset. Only "L3 mode"
(now called "raw mode") is added by this patch. This mode does not allow
Ethernet header to be encapsulated in VXLAN-GPE when using ip route to
specify the encapsulation, IP header is encapsulated instead. The patch
does support Ethernet to be encapsulated, though, using ETH_P_TEB in
skb->protocol. This will be utilized by other COLLECT_METADATA users
(openvswitch in particular).
If there is ever demand for Ethernet encapsulation with VXLAN-GPE using
ip route, it's easy to add a new flag switching the interface to
"Ethernet mode" (called "L2 mode" in v1 of this patchset). For now,
leave this out, it seems we don't need it.
Disallowed more flag combinations, especially RCO with GPE.
Added comment explaining that GBP and GPE cannot be set together.

Garbled output for "ethtool -m ethX", in igb-driven NICs with module /
plugin EEPROM (i.e. SFP information). Each output data byte appears
duplicated.
In igb_ethtool.c, igb_get_module_eeprom() is reading the EEPROM via i2c;
the eeprom offset for each word that's read via igb_read_phy_reg_i2c()
was passed in #words, whereas it needs to be a byte offset.
This patches fixes the bug.

Message level can be set through ethtool, so deprecate module parameter
which is used to set the same.

The Intel i211 LOM PCIe Ethernet controllers' iNVM operates as an OTP
and has no external EEPROM interface [1]. The following allows the
driver to pickup the MAC address from a device tree blob when CONFIG_OF
has been enabled.

This patch enables bulk free in Tx cleanup for igb and cleans up the
boolean logic in the polling routines for igb in the hopes of avoiding
any mix-ups similar to what occurred with i40e and i40evf.

We were casting the addr as __beXX and then passing it into le32_to_cpu
because the device expects the MAC address to be in network order even
though the register set is little endian. Instead of casting it as __beXX
we can just cast it as __leXX in order to maintain consistency since the
region of memory is already in little endian order as far as we are
concerned.

With IPv4 and IPv6 now using the same format for checksums based on the
length of the frame we need to update the i40e and i40evf drivers so that
they correctly account for lengths greater than or equal to 64K.
With this patch the driver should now correctly update checksums for frames
up to 16776960 in length which should be more than large enough for all
possible TSO frames in the near future.
