Use the new fancy eth_get_headlen() to pull exactly the headers
into skb->head.
This speeds up GRE traffic (or more generally tunneled traffuc),
as GRO can aggregate up to 17 MSS per GRO packet instead of 8.

This patch updates some of the flow_dissector api so that it can be used to
parse the length of ethernet buffers stored in fragments. Most of the
changes needed were to __skb_get_poff as it needed to be updated to support
sending a linear buffer instead of a skb.
I have split __skb_get_poff into two functions, the first is skb_get_poff
and it retains the functionality of the original __skb_get_poff. The other
function is __skb_get_poff which now works much like __skb_flow_dissect in
relation to skb_flow_dissect in that it provides the same functionality but
works with just a data buffer and hlen instead of needing an skb.

====================
This change makes it so that the core path for the phy timestamping logic
is shared between skb_tx_tstamp and skb_complete_tx_timestamp. In addition
it provides a means of using the same skb clone type path in non phy
timestamping drivers.
The main motivation for this is to enable non-phy drivers to be able to
manipulate tx timestamp skbs for such things as putting them in lists or
setting aside buffer in the context block.
v2: Incorporated suggested changes from Willem de Bruijn and Eric Dumazet
dropped uneeded comment
restored order of hwtstamp vs swtstamp
added destructor for skb
Dropped usage of skb_complete_tx_timestamp as a kfree_skb w/ destructor
v3: Updated destructor handling and dealt with socket reference counting issues
v4: Split out combining destructors into a separate patch
====================
Since sock_efree and sock_demux are essentially the same code for non-TCP
sockets and the case where CONFIG_INET is not defined we can combine the
code or replace the call to sock_edemux in several spots. As a result we
can avoid a bit of unnecessary code or code duplication.

The phy timestamping takes a different path than the regular timestamping
does in that it will create a clone first so that the packets needing to be
timestamped can be placed in a queue, or the context block could be used.
In order to support these use cases I am pulling the core of the code out
so it can be used in other drivers beyond just phy devices.
In addition I have added a destructor named sock_efree which is meant to
provide a simple way for dropping the reference to skb exceptions that
aren't part of either the receive or send windows for the socket, and I
have removed some duplication in spots where this destructor could be used
in place of sock_edemux.

This change merges the shared bits that exist between skb_tx_tstamp and
skb_complete_tx_timestamp. By doing this we can avoid the two diverging as
there were already changes pushed into skb_tx_tstamp that hadn't made it
into the other function.
In addition this resolves issues with the fact that
skb_complete_tx_timestamp was included in linux/skbuff.h even though it was
only compiled in if phy timestamping was enabled.

Intel Wired LAN Driver Updates 2014-09-04
This series contains updates to i40e, i40evf, ixgbe and ixgbevf.
Catherine adds dual speed module support to i40e. Updates i40e to allow
the user to change link settings when the link is down.
Serey renames i40e_ndo_set_vf_spoofck() to i40e_ndo_set_vf_spookchk()
to be more consistent with what is defined in netdev and removes a
unnecessary variable assignment.
Jesse makes a malicious driver detection warning only print if extended
driver string is enabled for i40e. Fixes a panic under traffic load when
resetting or if/whenever there was a Tx-timeout because we were enabling
the Tx queue to early.
Anjali fixes an issue when PF reset fails, where we were trying to restart
the admin queue which has not been setup at that point. This resolves an
occasional kernel panic when PF reset fails for some reason.
Ethan Zhao replaces the use of a local i40e_vfs_are_assigned() with the
global kernel pci_vfs_assigned() for i40e.
Alex cleans up the FDB handling for ixgbe. This change makes it so that
the behavior for FDB handling is consistent between both the SR-IOV and
non-SR-IOV cases. The main change is that we perform bounds checking on
the number of SR-IOV addresses regardless of if SR-IOV is enabled or not
as we can only support a certain number of addresses in the hardware.
Emil extends the pending Tx work check to the VF interfaces, where the
driver initiates a reset of the interface on link loss with pending Tx
work in order to clear the rings. Introduces a delay for 82599 VFs of
at least 500 usecs to make sure the VFLINKS value is correct, since this
bit tends to flap when a DA or SFP+ cable is disconnected.
Jacob adds code comments in ixgbe to make it more obvious that we are
resetting features based on the fact that we do not have MSI-X enabled,
and cannot use the previous settings. Also resolves a kernel NULL
pointer dereference by limiting the combined total of MACVLAN and
SR-IOV VFs, since the hardware has a limited number of pools available
(64). Previously, no checks were in place to limit the number of
accelerated MACVLAN devices based on the number of pools, which would
be ok since there was already a limit for these well below the number of
available pools. However, SR-IOV uses the very same pools, therefore
we need to ensure that the total number of pools does not exceed the
number of pools available in the hardware.
v2:
- clean up code comment in patch 5 by replacing "an" with "auto
negotiation" based on feedback from Sergei Shtylyov
- removed un-necessary parenthesis around function call in patch 8
based on feedback from Sergei Shtylyov
====================
Simplify the interrupt resource lookup code in cpsw_probe() by the
following:
* Only look at the first member of the resource. As the driver only
works for DT-enabled platforms anyway, a resource of type
IORESOURCE_IRQ will only contain one single entry
(res->start == res->end), so there is no need for the iteration.
* Add a bounds check to avoid overflows if we are passed more than
ARRAY_SIZE(priv->irqs_table) resources.
* Assign 'ret' with the return value of devm_request_irq() so that
cpsw_probe() returns the appropriate error code.
* If devm_request_irq() fails, report the error code in the log
message.

enic: Add support for rx_copybreak
The following series implements rx_copybreak.
dma_map_single()/dma_unmap_single() is more expensive than alloc_skb & memcpy
for smaller packets. By doing this we can reuse the dma buff which is already
mapped. This is very useful when iommu is on. The default skb copybreak value
is 256.
When iommu is on, we can go much higher than 256. All the drivers that supports
rx_copybreak provides module parameter to change this value. Since module
parameter is the least preferred way for changing driver values, this series
adds ethtool support for setting rx_copybreak.

Marcel reported to see the following message when autoloading
is being triggered when adding nlmon device:
Loading kernel module for a network device with
CAP_SYS_MODULE (deprecated). Use CAP_NET_ADMIN and alias
netdev-nlmon instead.
This false-positive happens despite with having correct
capabilities set, e.g. through issuing `ip link del dev nlmon`
more than once on a valid device with name nlmon, but Marcel
has also seen it on creation time when no nlmon module is
previously compiled-in or loaded as module and the device
name equals a link type name (e.g. nlmon, vxlan, team).
Stephen says:
The netdev module alias is a hold over from the past. For
normal devices, people used to create a alias eth0 to and
point it to the type of network device used, that was back
in the bad old ISA days before real discovery.
Also, the tunnels create module alias for the control device
and ip used to use this to autoload the tunnel device.
The message is bogus and should just be removed, I also see
it in a couple of other cases where tap devices are renamed
for other usese.
As mentioned in 8909c9ad8f ("net: don't allow CAP_NET_ADMIN
to load non-netdev kernel modules"), we nevertheless still
might want to leave the old autoloading behaviour in place
as it could break old scripts, so for now, lets just remove
the log message as Stephen suggests.

With eBPF getting more extended and exposure to user space is on it's way,
hardening the memory range the interpreter uses to steer its command flow
seems appropriate. This patch moves the to be interpreted bytecode to
read-only pages.
In case we execute a corrupted BPF interpreter image for some reason e.g.
caused by an attacker which got past a verifier stage, it would not only
provide arbitrary read/write memory access but arbitrary function calls
as well. After setting up the BPF interpreter image, its contents do not
change until destruction time, thus we can setup the image on immutable
made pages in order to mitigate modifications to that code. The idea
is derived from commit 314beb9bca ("x86: bpf_jit_comp: secure bpf jit
against spraying attacks").
This is possible because bpf_prog is not part of sk_filter anymore.
After setup bpf_prog cannot be altered during its life-time. This prevents
any modifications to the entire bpf_prog structure (incl. function/JIT
image pointer).
Every eBPF program (including classic BPF that are migrated) have to call
bpf_prog_select_runtime() to select either interpreter or a JIT image
as a last setup step, and they all are being freed via bpf_prog_free(),
including non-JIT. Therefore, we can easily integrate this into the
eBPF life-time, plus since we directly allocate a bpf_prog, we have no
performance penalty.
Tested with seccomp and test_bpf testsuite in JIT/non-JIT mode and manual
inspection of kernel_page_tables. Brad Spengler proposed the same idea
via Twitter during development of this patch.

When we bring the interface down, phy_stop() will schedule the PHY
state machine to call our link adjustment callback. By the time we do so,
we may have clock gated off the SYSTEMPORT hardware block, and this will
cause bus errors to happen in bcm_sysport_adj_link():
Make sure that we only touch the UMAC_CMD register when there is an
actual link. This is safe to do for two reasons:
- updating the Ethernet MAC registers only make sense when a physical
link is present
- the PHY library state machine first set phydev->link = 0 before
invoking phydev->adjust_link in the PHY_HALTED case
This is a similar fix to the GENET one:
